## Authoritative Agent Contract

Guide: https://miosa.ai/docs/guides/agent-operating-guide

- Run `miosa capabilities --json`, `miosa app inspect`, and `miosa app plan` before reconstructing a workflow from old examples.
- Resolve one exact organization, workspace, application, and environment before mutating resources.
- Reuse the linked persistent sandbox unless it is proven terminal. Do not replace resources because an identifier or route was not resolved.
- Use `miosa app preview` to create and test an immutable candidate release. Preview never promotes production.
- Verify and promote one exact release ID. Never promote an inferred latest release.
- Call a release live only when the active release, running artifact digest, route contract, placement, data bindings, and required configuration agree.
- Recover interrupted operations with the recorded operation ID and idempotency key instead of starting duplicates.
- Use URLs returned by MIOSA. Do not construct preview, deployment, or custom-domain hostnames.

# Agent Development Kit (ADK)

URL: https://miosa.ai/docs/adk
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/adk
Source: src/routes/docs/adk/+page.md
Description: Build LLM agents that use MIOSA sandboxes, desktops, and deploys with the tool-call loop already wired. TypeScript ADK first; Python next.

# Agent Development Kit (ADK)

The MIOSA ADK lets you build production-ready LLM agents that natively use
MIOSA primitives  -  sandboxes, full desktop environments, and one-click
deploys  -  with the tool-call loop already wired.

If `@miosa/sdk` is "call MIOSA APIs from code", `@miosa/adk` is **"build an
AGENT that uses MIOSA"**.

```bash
npm install @miosa/adk @anthropic-ai/sdk
```

---

## 30-second example

```typescript

const agent = new Agent({
  provider: anthropicProvider({
    apiKey: process.env.ANTHROPIC_API_KEY!,
    model: "claude-opus-4-7",
  }),
  miosaApiKey: process.env.MIOSA_API_KEY!,
});

const result = await agent.run({
  prompt:
    "Create a MIOSA sandbox, write a Python hello-world, run it, then destroy the sandbox.",
  maxIterations: 10,
});

console.log(result.finalText);
```

That's it. The agent boots a sandbox, writes the file, runs it, prints
output, destroys the sandbox, returns the final response. No tool-loop
boilerplate.

---

## ADK vs SDK

The raw TypeScript SDK around MIOSA's REST API. You call methods:

```typescript
const computer = await client.computers.create({ name: "x" });
await computer.exec.bash("echo hello");
```

Use this when you're **writing application code** that talks to MIOSA.

Adds the agent loop on top. You give it a provider + prompt:

```typescript
const agent = new Agent({ provider, miosaApiKey });
await agent.run({ prompt: "build a flask app and run it" });
```

Use this when you're **building an agent** that should use MIOSA.

---

## Built-in MIOSA tools

When you pass `miosaApiKey`, the agent gets these tools out of the box:

| Tool | Does |
|------|------|
| `create_sandbox` | Boot a Debian 12 microVM (Python + Node). |
| `create_desktop` | Start a full desktop environment. |
| `list_sandboxes` | List your active computers. |
| `get_sandbox` | Fetch one sandbox by id (status / IP). |
| `destroy_sandbox` | Delete a computer. |
| `exec` | Run a bash command. |
| `exec_python` | Run a Python snippet inline. |
| `read_file` | Read a file from the VM. |
| `write_file` | Write a file inside the VM. |
| `list_files` | List a directory inside the VM. |

Get an API key at <https://miosa.ai/dashboard/api-keys>, or run
`npx -y @miosa/cli mcp install` to wire one via browser-based auth.

---

## Custom tools

Compose your own tool catalogue alongside (or instead of) the MIOSA tools:

```typescript

  Agent,
  anthropicProvider,
  miosaTools,
  type Tool,
} from "@miosa/adk";

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const sendSlack: Tool = {
  name: "send_slack",
  description: "Post a message to the #builds Slack channel.",
  inputSchema: {
    type: "object",
    properties: { text: { type: "string" } },
    required: ["text"],
  },
  async execute(args) {
    const text = String(args["text"] ?? "");
    // your Slack call here
    return `Sent: ${text}`;
  },
};

const agent = new Agent({
  provider: anthropicProvider({ apiKey: process.env.ANTHROPIC_API_KEY! }),
  tools: [...miosaTools({ client: miosa }), sendSlack],
});
```

---

## Streaming step events

Drive a live UI as the agent runs:

```typescript
const result = await agent.run({
  prompt: "...",
  onStep: (step) => {
    console.log(`[turn ${step.index}] ${step.text}`);
    for (const call of step.toolCalls) {
      console.log(
        `  → ${call.name}(${JSON.stringify(call.input)}) → ${call.output.slice(0, 80)}`,
      );
    }
  },
});
```

The `AgentStep` shape:

```typescript
interface AgentStep {
  index: number;
  text: string;
  toolCalls: Array<{
    id: string;
    name: string;
    input: Record<string, unknown>;
    output: string;
    isError: boolean;
  }>;
  usage?: { inputTokens: number; outputTokens: number };
}
```

---

## Providers

`@miosa/adk` ships with native tool-call providers for hosted, marketplace, and
local OpenAI-compatible models, plus Anthropic and Gemini-specific adapters. The
same provider interface also works for custom internal routers.

```typescript

const provider = anthropicProvider({
  apiKey: process.env.ANTHROPIC_API_KEY!,
  model: "claude-opus-4-7", // default
  maxTokens: 4096, // default
});
```

Uses `@anthropic-ai/sdk` Messages API with native tool-use. Supports any
Claude model that supports tool calling.

```typescript

const provider = surplusProvider({
  apiKey: process.env.SURPLUS_API_KEY!,
  model: "claude-opus-4.8",
});
```

Surplus uses the OpenAI-compatible chat completions contract. In platform
runtime profiles, prefer routing through MIOSA's Intelligence API/model route so
keys can be metered, audited, revoked, and used as fallback fuel for Claude Code,
Codex, Hermes, OSA, or custom harnesses inside MIOSA sandboxes.

```typescript

const provider = miosaRouteProvider({
  miosaApiKey: process.env.MIOSA_API_KEY!,
  model: "optimal",
});
```

Use this when the agent should call MIOSA's Intelligence API rather than a
third-party provider directly. As model routes ship, the model can become a
route id such as `route:cheap-claude-code`; MIOSA then owns provider selection,
fallbacks, metering, and secret handling.

```typescript

const openai = openAIProvider({
  apiKey: process.env.OPENAI_API_KEY!,
  model: "gpt-5",
});

const groq = groqProvider({
  apiKey: process.env.GROQ_API_KEY!,
  model: "moonshotai/kimi-k2-instruct-0905",
});

const internal = openAICompatibleProvider({
  name: "internal-router",
  baseUrl: "https://llm.example.com/v1/chat/completions",
  apiKey: process.env.INTERNAL_LLM_KEY,
  model: "best-agent-model",
});
```

The bundled OpenAI-compatible provider covers OpenAI, Groq, DeepSeek,
OpenRouter, Together, Fireworks, Mistral, Cerebras, Perplexity, xAI, Surplus,
MIOSA Intelligence, Ollama, LM Studio, and custom routers.

Implement the `Provider` interface directly when an endpoint needs a custom tool
or streaming protocol.

---

## Termination

`agent.run()` returns when:

- The model emits an `end_turn` with no further tool calls (normal completion)
- A `stop_sequence` is hit
- `maxIterations` is reached (default 10)  -  safety guard against runaway loops
- The provider throws (returned as `stopReason: "error"`)

```typescript
const result = await agent.run({ prompt: "...", maxIterations: 20 });
if (result.stopReason === "max_iterations") {
  console.warn("Agent didn't finish in 20 turns");
}
```

---

## Quick comparison

| | `@miosa/adk` | Anthropic Claude Agent SDK | OpenAI Agents SDK | Google ADK |
|--|--|--|--|--|
| Tool-call loop | ✓ | ✓ | ✓ | ✓ |
| MIOSA tools built-in | **✓** |  -  |  -  |  -  |
| Anthropic provider | ✓ | ✓ |  -  |  -  |
| OpenAI-compatible providers | ✓ |  -  | ✓ |  -  |
| Sub-agents | (roadmap) | ✓ | ✓ | ✓ |
| Memory | (roadmap) | ✓ | (basic) | ✓ |
| Cost | free | free | free | free |

The ADK is intentionally small. If you want MIOSA-as-execution-substrate
with a clean agent loop, you're in the right place.

---

## What's coming next

- **Python ADK** (`pip install miosa-adk`)  -  same surface, Python ergonomics.
- **Managed model routes**  -  route ADK and in-sandbox harness calls through MIOSA Intelligence API.
- **Sub-agents**  -  spawn child agents with scoped tool subsets.
- **Memory**  -  built-in conversation memory with TTL + summarization.
- **Streaming output**  -  token-by-token via provider.streamStep.

# Agent Studio

URL: https://miosa.ai/docs/agents/agent-studio
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/agents/agent-studio
Source: src/routes/docs/agents/agent-studio/+page.md
Description: Chat with an agent in a dedicated workspace, with one warm sandbox per chat and honest status and errors.

Agent Studio is the chat-first way to use a saved agent.
The chat is the main surface, and the canvas folds into a slim strip you can reopen.

## One sandbox per chat

A chat gets one warm sandbox, and follow-ups reuse it.
A paused sandbox is woken with its files.
Only a destroyed sandbox is replaced, and the chat says so.

## Honest status and errors

The status line shows what is happening: starting the sandbox, starting the agent, thinking.
A failed message shows the platform's own message, its code, and one hint, shown once on the turn.

## The workspace panel

A workspace panel sits beside the chat, with the same tabs as Optimal:

- Preview
- Files
- Code
- Terminal
- Machine
- Logs

It opens on the chat's first activity and shows the chat's own sandbox.

## A clean conversation

Harness wording such as Overdrive warnings and the stdin banner never reaches the chat.
Overdrive is one quiet chip beside the composer with a tooltip.
Tool rows stay inside the chat: a long argument can no longer widen it, and commands, arguments, and JSON output are readable.

Past chats are kept per agent in both Agent Studio and the agent page.

# Chat with an agent on a machine

URL: https://miosa.ai/docs/agents/chat-on-a-machine
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/agents/chat-on-a-machine
Source: src/routes/docs/agents/chat-on-a-machine/+page.md
Description: Open a computer, or the Agent section of a sandbox, and chat with an agent bound to that machine.

Opening a computer, or the Agent section of a sandbox, opens one chat bound to that machine.
The workspace panel sits beside it.

## Pick the brain in the chat

Before the first message you choose what powers the chat:

- **Optimal** runs a machine-bound chat on wallet credits.
- **A harness** runs on your own account: Claude Code, Codex, OSA, pi, OpenCode, Prime Agent, Kimi Code, or Mistral Vibe.
- **A saved agent** runs with its own instructions, tools, and permissions.

The chat is bound to the machine you opened, so there is no "where should you build?" step.

The brain is remembered per person, per workspace, and per machine.
It never changes the brain you picked on the [Optimal](/docs/optimal/) page.

## While it works

- Switching the brain stops the run, keeps the old thread above a divider, and starts a new thread.
- A Connect card opens when your account is not connected.
- Approvals appear inline, and you can approve or deny.
- **Stop** cancels the run.
- **Take over** hands control to you, and **Hand back** returns it.

## The panel follows the machine

The workspace panel opens on Desktop for a computer and on Terminal for a sandbox, then Preview once a URL exists.
It restores the layout you had on the Optimal page when you leave.

A machine that belongs to another workspace never gets a chat, a chat id, or a run.

# Agent confinement

URL: https://miosa.ai/docs/agents/confinement
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/agents/confinement
Source: src/routes/docs/agents/confinement/+page.md
Description: An agent runs inside its machine and cannot use MIOSA's own platform key unless an Environment grants it a scoped one.

An agent runs inside its machine and stays there.
It cannot use MIOSA's own platform key to reach the rest of the platform.

## The platform key is blanked

Every sandbox boots with a platform key and its ids in the environment, so a plain command can call MIOSA.

Harness runs do not get it.
When MIOSA starts a harness, it blanks the platform key and the ids at launch, and unsets them in the run script.
So Claude Code, Codex, OSA, pi, OpenCode, Prime Agent, Kimi Code, Mistral Vibe, and Hermes Agent cannot borrow MIOSA's key.

## Grant a scoped key with an Environment

When you want an agent to reach MIOSA on purpose, an [Environment](/docs/cli/environments/) can grant it a scoped machine key.
That key is bound to the machine, not to your account.

## What is kept

- A value the run itself supplies is kept.
- Environment grants are not touched.

# Harnesses and auth

URL: https://miosa.ai/docs/agents/harnesses
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/agents/harnesses
Source: src/routes/docs/agents/harnesses/+page.md
Description: The agents MIOSA can run on your machine, how each one authenticates, and how MIOSA gets each one ready.

A harness is a coding agent MIOSA runs on a machine, on your own account.
MIOSA never falls back to its own keys.

## The harnesses

| Harness | `runner` |
|---|---|
| Claude Code | `claude-code` |
| Codex | `codex` |
| OSA | `osa` |
| pi | `pi` |
| OpenCode | `opencode` |
| Prime Agent | `prime` |
| Kimi Code | `kimi` |
| Mistral Vibe | `mistral` |
| Hermes Agent | `hermes` |

There is also `custom` for a gateway model, which runs on MIOSA's AI Gateway.

## How MIOSA gets them ready

Runs are fast because a machine rarely installs anything at run time.

| Ready | Harnesses |
|---|---|
| Prebaked in the machine image | Claude Code, Codex, OSA |
| Installed on first use | pi, OpenCode, Prime Agent, Kimi Code, Mistral Vibe |
| Add-on, installed at create | Hermes Agent |

Hermes Agent is a large install, about 2.5 GB, so it is added at create and cached per host.

## Which account powers which harness

A Connection you make once is reused by every harness that accepts it.
Connect a ChatGPT plan once, and Codex, pi, OpenCode, Prime Agent, and Hermes Agent all use it.

| Harness | Plans | API keys |
|---|---|---|
| Claude Code | Claude plan | Anthropic, OpenRouter, DeepSeek; Amazon Bedrock |
| Codex | ChatGPT plan | OpenAI, DeepSeek; Amazon Bedrock |
| OSA | | Ollama Cloud; Anthropic, OpenAI, OpenRouter |
| pi | Claude plan, ChatGPT plan, Mistral Vibe key | Anthropic, OpenAI, OpenRouter, Mistral, LLM Gateway |
| OpenCode | ChatGPT plan, Mistral Vibe key | Anthropic, OpenAI, OpenRouter, Mistral, LLM Gateway |
| Prime Agent | Claude plan, ChatGPT plan, Mistral Vibe key | Anthropic, OpenAI, OpenRouter, Mistral, LLM Gateway |
| Kimi Code | Kimi Code plan | Moonshot |
| Mistral Vibe | Mistral Vibe key | Mistral |
| Hermes Agent | ChatGPT plan, Claude plan (Max with extra usage) | Anthropic, OpenAI, OpenRouter |

Two caveats to know:

- **OpenCode cannot use a Claude plan.** Anthropic does not allow it, and OpenCode removed the plugins that did it.
- **Hermes Agent on a Claude plan needs a Claude Max plan with extra usage credits.** A Claude Pro plan is refused.

## Hermes Agent

Hermes Agent is a first-class runner in the run API: send `runner: "hermes"` to `POST /api/v1/runs`.
It is not in the CLI `--harness` list yet, so use the API or the console until it is.

MIOSA runs the platform's pinned Hermes version, and never installs a newer one.
A Hermes run without an account returns `OWN_CREDENTIALS_REQUIRED`, the same as any other harness.

## The harness list as an API

`GET /api/v1/agents/harnesses` returns each harness with:

- `supported_auth`: the accounts that can power it, in the order the run path tries them.
  Each has `id`, `label`, `kind`, `vendor`, `injection`, `model`, `source`, and `note`.
- `also_supports`: what the agent's own CLI takes that MIOSA does not connect yet.
- `unsupported_auth`: what a person may expect to work but the vendor refuses, with `reason` and `source`.

Each model carries `served_by`, the account ids that can run it.

Refresh tokens never reach a machine.
The control plane is the single refresh owner, and hands the machine a short-lived access token that outlives the run.

# API Reference

URL: https://miosa.ai/docs/api-reference
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference
Source: src/routes/docs/api-reference/+page.md
Description: REST API reference for the MIOSA platform - base URL, auth, request/response envelopes, and endpoint guides.

Want to browse and try endpoints without writing code?
  The <a href="/docs/api">Interactive Sandbox API Reference</a> renders the
  allowlisted public Sandbox V1 OpenAPI contract with an in-browser request runner.
  Use the endpoint guides below for the wider platform API.

Every MIOSA API endpoint is REST over HTTPS, returns JSON, and follows a consistent envelope format. The SDKs wrap these endpoints  -  you can use them directly when you need low-level control or want to integrate from a language without an official SDK.

## Base URL
```

https://api.miosa.ai/api/v1
```

## Authentication

All requests require a Bearer token:
```http
Authorization: Bearer msk_u_...
```

MIOSA API keys (`msk_*`) and short-lived JWT tokens are both accepted. Keys are scoped to an organization and its workspaces/projects. See [API Keys](/docs/platform/api-keys/) for scope details.

## Request format

- `Content-Type: application/json` for all request bodies.
- File uploads use `multipart/form-data`.
- All field names are **snake_case**.
- Mutation requests (`POST`, `PUT`, `PATCH`, `DELETE`) should include an `Idempotency-Key` header to enable safe retries:
```http
POST /api/v1/sandboxes
Authorization: Bearer msk_u_...
Idempotency-Key: 550e8400-e29b-41d4-a716-446655440000
Content-Type: application/json

{
  "template": "miosa-sandbox",
  "workspace_slug": "acme-corp",
  "project_slug": "lead-magnet",
  "external_workspace_id": "acct_123",
  "external_user_id": "user-456",
  "external_project_id": "project_789"
}
```

Use a UUID v4 as the idempotency key. Repeating the same key within 24 hours returns the original response without re-executing the mutation.
The key also keeps a retry safe: an idempotent create whose placement outcome is uncertain answers a retryable `503 SANDBOX_PLACEMENT_RECONCILING` with `Retry-After` instead of a terminal `409`, so retrying with the same key resolves to the same sandbox.

## Response envelope

Single-resource responses:
```json
{
  "data": {
    "id": "550e8400-e29b-41d4-a716-446655440000",
    "name": "my-sandbox",
    "status": "running",
    "created_at": "2026-05-17T10:00:00Z"
  }
}
```

List responses include a pagination object:
```json
{
  "data": [ { "id": "...", "name": "..." } ],
  "page": {
    "page": 1,
    "page_size": 20,
    "total": 150
  }
}
```

Pagination parameters accepted by all list endpoints:

| Parameter | Type | Default | Max |
|---|---|---|---|
| `page` | integer | 1 |  -  |
| `page_size` | integer | 20 | 100 |

## Error envelope

All errors follow a single shape:
```json
{
  "error": {
    "code": "sandbox_not_found",
    "message": "No sandbox with id sbx_abc exists in this workspace.",
    "request_id": "req_01jv..."
  }
}
```

Include the `request_id` when contacting support.

### HTTP status codes

| Status | Meaning |
|---|---|
| 200 | Success |
| 201 | Created |
| 202 | Accepted  -  async operation started |
| 400 | Bad request  -  missing or invalid parameters |
| 401 | Unauthorized  -  invalid or missing token |
| 403 | Forbidden  -  valid token, insufficient scope |
| 404 | Not found |
| 409 | Conflict  -  invalid state transition (e.g. starting a running computer) |
| 413 | Payload too large  -  file upload exceeds 10 MB |
| 422 | Unprocessable entity  -  validation error |
| 429 | Rate limited |
| 500 | Internal server error |
| 502 | Bad gateway  -  command service unreachable |

## Rate limits

Rate limits apply per API key, tenant or organization, and endpoint family.
The current self-service defaults are 600 requests per minute for user keys and 30,000 requests per minute for platform keys.
Specific endpoint families and tenant policies can impose lower limits.
Treat `X-RateLimit-*` and `Retry-After` response headers as authoritative.

## IDs and timestamps

Canonical resource IDs returned by the current API are UUIDs.
Some older SDK examples and compatibility surfaces may still show human-readable aliases.
Pass the exact ID returned by the API instead of constructing or prefixing an identifier.
All timestamps are ISO 8601 in UTC: `2026-05-17T10:00:00Z`.

## Ownership fields

Create endpoints for resources accept the same ownership selectors:

| Field | Use |
|---|---|
| `workspace_id` | Existing MIOSA workspace UUID |
| `workspace_slug` | Existing or auto-created workspace slug |
| `workspace_name` | Display name used when auto-creating a workspace |
| `project_id` | Existing MIOSA project UUID |
| `project_slug` | Existing or auto-created project slug |
| `project_name` | Display name used when auto-creating a project |
| `external_workspace_id` | Your customer/account/workspace ID |
| `external_user_id` | Your end-user ID |
| `external_project_id` | Your project/app/document ID |

Responses include `workspace_id` and `project_id` when the resource is owned by a workspace/project. See [Ownership and Attribution](/docs/platform/attribution/).

# Agent Run Groups

URL: https://miosa.ai/docs/api-reference/agent-run-groups
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/agent-run-groups
Source: src/routes/docs/api-reference/agent-run-groups/+page.md
Description: Create durable multi-agent orchestration groups, dispatch run manifests, inspect counts, and cancel grouped work.

# Agent Run Groups

Agent Run Groups are the durable control-plane object for multi-agent fanout.
Use a group when one user request creates many related Agent Runs across
sandboxes, computers, or custom runtimes.

Base path: `/api/v1/agent-run-groups`

Use synchronous dispatch for small fanout where you want child run creation in
the response. Use `async: true` for queued fanout: MIOSA stores each manifest
entry, enforces the group's concurrency limit while workers claim entries, and
returns immediately with queued entry records.

## Endpoints

| Method | Path | Description |
|---|---|---|
| `GET` | `/api/v1/agent-run-groups` | List groups for the tenant |
| `POST` | `/api/v1/agent-run-groups` | Create a group |
| `GET` | `/api/v1/agent-run-groups/{id}` | Fetch one group |
| `POST` | `/api/v1/agent-run-groups/{id}/dispatch` | Dispatch a bounded manifest of child Agent Runs |
| `GET` | `/api/v1/agent-run-groups/{id}/events` | Replay or stream durable events from every child run in the group |
| `POST` | `/api/v1/agent-run-groups/{id}/cancel` | Cancel the group and running children |

## Create

```http
POST /api/v1/agent-run-groups
Authorization: Bearer msk_u_...
Content-Type: application/json
```

```json
{
  "name": "lumen-browser-checks",
  "workspace_id": "ws_123",
  "project_id": "proj_123",
  "concurrency_limit": 25,
  "expected_runs": 100,
  "metadata": {
    "user_task_id": "task_123"
  }
}
```

## Dispatch

Dispatch accepts a `runs` array. Each entry uses the same fields as
[Agent Runs](/docs/api-reference/agent-runs/), plus optional
`orchestration_role` and `parent_agent_run_id`.

```http
POST /api/v1/agent-run-groups/{id}/dispatch
Authorization: Bearer msk_u_...
Content-Type: application/json
```

```json
{
  "runs": [
    {
      "sandbox_id": "sbx_code_1",
      "provider": "claude-code",
      "cwd": "/workspace",
      "prompt": "Implement the pricing page and export /workspace/report.html",
      "orchestration_role": "coder",
      "metadata": {
        "artifact_paths": ["/workspace/report.html"]
      }
    },
    {
      "computer_id": "cmp_browser_1",
      "provider": "osa",
      "prompt": "Open the preview, test signup, and capture screenshots.",
      "orchestration_role": "browser-qa"
    }
  ],
  "async": true
}
```

Set `async` to `true` when the group should queue entries and return before the
child Agent Runs are created. MIOSA creates one durable entry per manifest item,
then dispatcher workers claim entries under the group's `concurrency_limit`.

Current dispatch batches are capped at `100` entries per request. For larger
fleets, shard logical work into multiple groups or dispatch batches from your
backend.

## Response

```json
{
  "data": {
    "group": {
      "id": "grp_123",
      "name": "lumen-browser-checks",
      "status": "running",
      "concurrency_limit": 25,
      "expected_runs": 100,
      "counts": {
        "total": 2,
        "running": 0,
        "succeeded": 2,
        "failed": 0,
        "canceled": 0
      },
      "entry_counts": {
        "total": 2,
        "queued": 0,
        "running": 0,
        "succeeded": 2,
        "failed": 0,
        "canceled": 0
      }
    },
    "results": [
      {
        "index": 0,
        "ok": true,
        "run": {
          "id": "run_123",
          "agent_run_group_id": "grp_123",
          "orchestration_role": "coder",
          "status": "succeeded"
        }
      }
    ],
    "entries": []
  }
}
```

Async dispatch returns `entries` immediately and usually returns an empty
`results` array:

```json
{
  "data": {
    "group": {
      "id": "grp_123",
      "status": "running",
      "concurrency_limit": 25,
      "entry_counts": {
        "total": 2,
        "queued": 2,
        "running": 0,
        "succeeded": 0,
        "failed": 0,
        "canceled": 0
      }
    },
    "results": [],
    "entries": [
      {
        "id": "agre_123",
        "agent_run_group_id": "grp_123",
        "index": 0,
        "status": "queued",
        "attempts": 0
      }
    ]
  }
}
```

## Events

Use group events when your UI needs one stream for an entire multi-agent task.
MIOSA records child Agent Run events and replays them through the group in
sequence order. This lets your product render progress from the coder, tester,
browser QA agent, and deployment verifier without opening one stream per child
run.

Replay existing events as JSON:

```http
GET /api/v1/agent-run-groups/{id}/events
Authorization: Bearer msk_u_...
```

Stream existing events plus live events with SSE:

```http
GET /api/v1/agent-run-groups/{id}/events?stream=true
Accept: text/event-stream
Authorization: Bearer msk_u_...
```

Event payloads include the group id, child run id, event sequence, event type,
message, payload, and timestamp:

```json
{
  "data": [
    {
      "id": "ev_123",
      "agent_run_group_id": "grp_123",
      "agent_run_id": "run_123",
      "sequence": 4,
      "type": "command_finished",
      "message": "Command completed",
      "payload": {
        "exit_code": 0
      },
      "created_at": "2026-06-15T21:20:00Z"
    }
  ]
}
```

Terminal group states close the SSE response after replay. Running groups keep
the stream open and emit heartbeat comments while waiting for new child events.

## SDK

```typescript
const group = await miosa.agentRunGroups.create({
  name: "lumen-browser-checks",
  workspaceId: "ws_123",
  concurrencyLimit: 25,

# Agent Runs

URL: https://miosa.ai/docs/api-reference/agent-runs
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/agent-runs
Source: src/routes/docs/api-reference/agent-runs/+page.md
Description: Dispatch prompts into MIOSA devices with a stable run response shape for agent work.

# Agent Runs

Agent Runs are the prompt-dispatch interface for MIOSA sandboxes and computers.
Use them when your product needs to send a natural-language task into a device, run it
through OSA, Codex, Claude Code, Pi, Hermes, or a custom runtime, and receive a
stable run response your UI can render.

This is the API behind:

- `miosa agent run --sandbox ...`
- `miosa agent run --computer ...`
- `miosa prompt`
- `client.agentRuns.run(...)` in the TypeScript SDK
- `client.agent_runs.run(...)` in the Python SDK
- `miosa run files <run-id>`
- `miosa run download <run-id> <file-id>`

Use raw exec when you already know the command. Use Agent Runs when the user
prompt should be handled by an agent runtime inside a MIOSA device. The run
response preserves prompt, provider, target, output, error, metadata, and
timestamps for your product UI and audit trail.

## Flow

## Create a run

```http
POST /api/v1/agent-runs
Authorization: Bearer msk_u_...
Content-Type: application/json
```

`POST /agent-runs` is live for sandbox and computer targets. Use sandbox targets
for code, files, tests, builds, artifacts, and preview servers. Use computer
targets when the task needs a browser, desktop, screenshots, or interactive UI
state. For customer-owned OpenComputers hosts, use
`POST /opencomputers/hosts/{id}/agent/dispatch`.

```json
{
  "target_kind": "sandbox",
  "target_id": "41026070-9bb0-4d62-90b4-8ceeb0a131b6",
  "provider": "claude-code",
  "prompt": "Update the landing page, run tests, and leave the preview running.",
  "cwd": "/workspace",
  "timeout": 1800,
  "metadata": {
    "workspace_id": "lumen",
    "task_id": "task_123"
  }
}
```

## Response

```json
{
  "data": {
    "id": "b1772e2f-89d1-4b59-9aa7-147eed4c902a",
    "agent_run_group_id": "grp_123",
    "parent_agent_run_id": null,
    "orchestration_role": "coder",
    "target_kind": "sandbox",
    "target_id": "41026070-9bb0-4d62-90b4-8ceeb0a131b6",
    "provider": "claude-code",
    "prompt": "Update the landing page, run tests, and leave the preview running.",
    "status": "succeeded",
    "output": "Updated app/page.tsx and started preview on port 3000.",
    "stderr": "",
    "exit_code": 0,
    "metadata": {
      "workspace_id": "lumen",
      "task_id": "task_123"
    },
    "started_at": "2026-06-14T10:30:00Z",
    "finished_at": "2026-06-14T10:31:42Z",
    "created_at": "2026-06-14T10:30:00Z",
    "updated_at": "2026-06-14T10:31:42Z"
  }
}
```

### Status values

| Status | Meaning |
|---|---|
| `running` | Reserved for async run history. |
| `succeeded` | The runtime completed successfully. |
| `failed` | The runtime returned a non-zero exit or backend error. |
| `canceled` | The run was canceled. For sandbox process-backed runs, MIOSA also stops the recorded sandbox process. |

## Artifacts

Agent runs can record generated files as artifacts. MIOSA captures declared
artifact bytes into managed storage when possible, then falls back to the live
target filesystem for older or unpersisted artifacts.

That matters for product UX: if `persisted` is `true`, your users can download
the file even after the sandbox or computer session has stopped. If `persisted`
is `false`, keep the target running until the file has been downloaded,
exported, or published.

Declare artifact paths in the request body:

```json
{
  "sandbox_id": "41026070-9bb0-4d62-90b4-8ceeb0a131b6",
  "provider": "claude-code",
  "prompt": "Create /workspace/report.html",
  "metadata": {
    "artifact_paths": ["/workspace/report.html"]
  }
}
```

List artifacts:

```http
GET /api/v1/agent-runs/{run_id}/artifacts
Authorization: Bearer msk_u_...
```

Download one artifact:

```http
GET /api/v1/agent-runs/{run_id}/artifacts/{artifact_id}/download
Authorization: Bearer msk_u_...
```

Use `?disposition=inline` when embedding an HTML/PDF/image artifact in your own
preview UI. The default response is an attachment.

Artifact list responses also include short-lived `signed_download_url` values
when the backend can mint them. Use these URLs for browser-facing downloads in
your own UI; they do not require exposing the user's API key.

Artifact records include persistence metadata:

| Field | Meaning |
|---|---|
| `status` | Artifact lifecycle status such as `created`, `available`, or `failed`. |
| `sha256` | Content hash when MIOSA captured bytes. |
| `persisted` | `true` when the bytes are stored outside the live runtime. |
| `storage_backend` | Storage backend label, for example `s3` or `local`. |
| `persisted_at` | Timestamp when MIOSA captured the bytes. |

MIOSA does not expose internal storage keys or bucket URLs in the public API.
Use the download endpoint or signed download URL instead.

## Events

Agent Run events are durable. Use them to build timelines, progress feeds,
audit trails, and orchestration UIs.

| Event | Meaning |
|---|---|
| `created` | Run record was created. |
| `command_started` | MIOSA started executing the runtime command. |
| `process_started` | Sandbox process-backed run started and recorded a sandbox process id. |
| `command_finished` | Runtime command finished and the run was marked succeeded or failed. |
| `artifacts_recorded` | Declared artifacts were captured or recorded. |
| `failed` | Run failed before normal command completion. |
| `canceled` | Run was canceled. |

List durable events:

```http
GET /api/v1/agent-runs/{run_id}/events
Authorization: Bearer msk_u_...
```

Stream events with SSE:

```http
GET /api/v1/agent-runs/{run_id}/events?stream=true
Accept: text/event-stream
Authorization: Bearer msk_u_...
```

The stream sends existing durable events first, then live PubSub events. Terminal
events such as `command_finished`, `failed`, and `canceled` close the stream.

## Cancellation

```http
POST /api/v1/agent-runs/{run_id}/cancel
Authorization: Bearer msk_u_...
```

Cancellation is best-effort by target type:

| Target | Behavior |
|---|---|
| Sandbox process-backed run | MIOSA stops the recorded sandbox process, marks the run `canceled`, and emits `canceled`. |
| Older synchronous sandbox path | MIOSA marks the run `canceled`; the command may already have completed by the time cancellation is received. |
| Computer/BYOC target | MIOSA marks the run `canceled`; computer runtime interruption depends on the target agent implementation. |

For sandbox process-backed runs, the run metadata includes:

```json
{
  "agent_process": {
    "target_kind": "sandbox",
    "target_id": "41026070-9bb0-4d62-90b4-8ceeb0a131b6",
    "process_id": "proc_123",
    "pid": 123,
    "started_at": "2026-06-15T16:45:00Z"
  }
}
```

## Run history

Use the response from `POST /agent-runs` for the immediate task result. For
long-running browser or desktop conversations, keep using the Computer session
APIs alongside Agent Runs so your UI can show both the interactive session and
the per-prompt run result.

## SDK examples

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const run = await client.agentRuns.run({
  sandboxId: "41026070-9bb0-4d62-90b4-8ceeb0a131b6",
  targetKind: "sandbox",
  agentRunGroupId: "grp_123",
  orchestrationRole: "coder",
  agentRuntimeProfileId: "arp_123",
  provider: "claude-code",
  cwd: "/workspace",
  timeout: 1800,
  prompt: "Build the dashboard, run tests, and keep the preview live.",
  metadata: {
    artifact_paths: ["/workspace/report.html"],
  },
});

console.log(run.id, run.status, run.output);

const artifacts = await client.agentRuns.artifacts(run.id);
const report = await client.agentRuns.downloadArtifact(run.id, artifacts[0].id);
```

```python
from miosa import Miosa

client = Miosa()

run = client.agent_runs.run(
    sandbox_id="41026070-9bb0-4d62-90b4-8ceeb0a131b6",
    target_kind="sandbox",
    agent_run_group_id="grp_123",
    orchestration_role="coder",
    agent_runtime_profile_id="arp_123",
    provider="claude-code",
    cwd="/workspace",
    timeout=1800,
    prompt="Build the dashboard, run tests, and keep the preview live.",
    metadata={"artifact_paths": ["/workspace/report.html"]},
)

print(run["id"], run["status"], run.get("output", ""))

artifacts = client.agent_runs.artifacts(run["id"])
report = client.agent_runs.download_artifact(run["id"], artifacts[0]["id"])
```

## CLI

Use `miosa prompt` when choosing the target the run executes on:

```bash
miosa prompt "Build the dashboard, run tests, and keep the preview live." \
  --sandbox 41026070-9bb0-4d62-90b4-8ceeb0a131b6 \
  --harness claude-code \
  --max-time 1800 \
  --json

miosa prompt "Open the CRM and verify the lead import" \
  --computer desktop-prod-1 \
  --harness osa \
  --json

miosa api POST /opencomputers/hosts/host_abc123/agent/dispatch \
  -d '{"task": "Audit the local browser workflow"}'

miosa run files <run-id> --json
miosa run download <run-id> <file-id> --output ./report.html
```

Use `miosa agent run` when you have a saved agent to run with the standard
harness:

```bash
miosa agent run builder \
  --sandbox 41026070-9bb0-4d62-90b4-8ceeb0a131b6 \
  --json \
  "Build the dashboard, run tests, and keep the preview live."
```

Use the API-level `command` field with `provider: "custom"` when you bring your
own runtime harness. The CLI exposes the built-in providers first.

## Product guidance


    Render the run status, provider, target, prompt, output, and request id in
    your task stream so users can see what the agent did.


    The agent should write files and run commands inside the sandbox, not build
    locally and upload a finished result afterward.


    Store your workspace, user, project, artifact, or task ids in metadata so
    you can connect MIOSA runs to your product records.


    Store your own dispatch id in `metadata` when sending work from queues. The
    queryable run store will use the same response shape when retry-safe
    history lands.

# Agent Runtime Profiles

URL: https://miosa.ai/docs/api-reference/agent-runtime-profiles
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/agent-runtime-profiles
Source: src/routes/docs/api-reference/agent-runtime-profiles/+page.md
Description: Configure reusable agent runtime defaults for sandboxes, computers, and custom agent sessions.

# Agent Runtime Profiles

Agent Runtime Profiles define how MIOSA should prepare an agent runtime for a
tenant, workspace, or project. Use profiles to standardize OSA, Codex, Claude
Code, Pi, Hermes, or custom runtimes across sandboxes and computers without
passing the same model, tools, connectors, policy, and environment on every run.

Base path: `/api/v1/agent-runtime-profiles`

Profiles configure runtime shape. Agent Runs still provide the prompt, target,
timeout, and task-specific metadata.

## Endpoints

| Method | Path | Description |
|---|---|---|
| `GET` | `/api/v1/agent-runtime-profiles` | List profiles for the tenant |
| `POST` | `/api/v1/agent-runtime-profiles` | Create a profile |
| `GET` | `/api/v1/agent-runtime-profiles/{id}` | Fetch one profile |
| `PUT` | `/api/v1/agent-runtime-profiles/{id}` | Update a profile |
| `DELETE` | `/api/v1/agent-runtime-profiles/{id}` | Delete a profile |

List can be filtered with `workspace_id` or `project_id`.

## Create

```http

## Fields

| Field | Description |
|---|---|
| `name` | Human-readable profile name. Unique within the relevant tenant/workspace/project scope. |
| `runtime` | One of `osa`, `codex`, `claude`, `claude-code`, `pi`, `hermes`, or `custom`. |
| `workspace_id` | Optional workspace scope. |
| `project_id` | Optional project scope. |
| `description` | Operator-facing explanation. |
| `applies_to` | Resource selector, commonly `{ "resources": ["sandbox", "computer"] }`. |
| `tools` | Tool ids the runtime should expect, such as `filesystem`, `shell`, `browser`, `artifacts`, or `deployments`. |
| `connectors` | Connector UIDs to bind when the target runtime is created. |
| `env` | Non-secret runtime defaults. Put provider keys in runtime env/secrets, not here. |
| `policy` | Product policy such as approvals, max child runs, or external-write rules. |
| `metadata` | Product-specific labels and ids. |
| `is_default` | Whether MIOSA should resolve this profile by default for the scope and resource family. |

## Resolution

Agent Runs can pass `agent_runtime_profile_id` explicitly. If they do not,
MIOSA resolves defaults by scope and target family:

```text
explicit run profile
  -> project default
  -> workspace default
  -> tenant default
  -> no profile
```

The profile can be applied when creating or running sandboxes, computers, and
OpenComputer/BYOC agent sessions. Request-level `env` values override non-secret
profile env values for that single run.

## CLI

Agent Runtime Profiles have no dedicated `miosa` subcommand; drive them with
`miosa api` against the `/agent-runtime-profiles` endpoint.

```bash
miosa api GET /agent-runtime-profiles?workspace_id=ws_123

miosa api POST /agent-runtime-profiles -d '{
  "name": "lumen-claude",
  "runtime": "claude-code",
  "workspace_id": "ws_123",
  "project_id": "proj_123",
  "tools": ["filesystem", "shell", "browser", "artifacts"],
  "connectors": ["anthropic/lumen", "refero/managed"],
  "env": {"ANTHROPIC_MODEL": "claude-sonnet-4.6"},
  "policy": {"approval_required_for": ["deploy", "external_write"]},
  "is_default": true
}'

miosa api PUT /agent-runtime-profiles/arp_123 -d '{"runtime": "codex"}'
miosa api DELETE /agent-runtime-profiles/arp_123
```

## Next


    Store inherited environment variables for tenant, workspace, project, and target scopes.


    Dispatch prompts into a sandbox, computer, or custom runtime.


    Use runtime profiles with groups, events, artifacts, and multi-agent fanout.

---

## Pagination

Audit events are returned newest-first. To page forward:

1. Issue the initial request without `after`.
2. If `next_cursor` is present, re-issue with `after={next_cursor}`.
3. Stop when `next_cursor` is absent.

Cursors are opaque base64url strings encoding a timestamp. Do not parse or construct them.

# Cloud and BYOC API

URL: https://miosa.ai/docs/api-reference/cloud
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/cloud
Source: src/routes/docs/api-reference/cloud/+page.md
Description: Organization-scoped AWS and GCP accounts, regions, pools, nodes, preflight, and host provisioning.

Base path: `/api/v1/cloud`

All resources belong to the active organization, which is returned as both `organization_id` and the compatibility field `tenant_id`.
Cloud reads require `cloud:read` and mutations require `cloud:write`.
Organization members can read inventory.
Organization owners and admins can mutate it.
Workspace-scoped credentials cannot mutate organization cloud capacity.

AWS and GCP BYOC are gated private previews.
Provider connection and preflight do not make workload placement selectable.
Each exact organization, region, provider, and workload combination needs a current verification receipt from a real accepted host.

## Accounts

- `GET /cloud/accounts` lists organization cloud accounts.
- `POST /cloud/accounts` creates an AWS or GCP customer BYOC trust boundary.
- `POST /cloud/accounts/{id}/aws-role` attaches an AWS AssumeRole ARN and generated external ID.
- `POST /cloud/accounts/{id}/gcp-workload-identity` attaches the GCP project, customer actuator service account, and separate least-privilege worker service account without storing a service-account key.

## Regions

- `GET /cloud/regions?cloud_account_id={id}` lists configured regions.
- `POST /cloud/regions` records provider region, zone, network, host image, and exact immutable artifact configuration.
- `PATCH /cloud/regions/{id}` updates that configuration and clears stale preflight readiness.

Every launchable region must provide an HTTPS manifest URI, lowercase SHA-256 digest, version bound into the URI, and positive artifact generation.

## Pools

- `GET /cloud/pools?cloud_region_id={id}` lists desired host pools.
- `POST /cloud/pools` creates a pool configuration.
- `PATCH /cloud/pools/{id}` updates organization capacity and placement guardrails.
- `POST /cloud/pools/{pool_id}/provision` explicitly launches between 1 and 50 hosts.

```json
{
  "count": 1
}
```

Provisioning returns one result per requested host.
A successful launch starts in `provider_pending` and is not schedulable until host acceptance passes.

## Nodes

- `GET /cloud/nodes?cloud_pool_id={id}` lists provider and acceptance state for a pool.

Important node states include `provider_pending`, `acceptance_running`, `active`, `draining`, `terminated`, and `failed`.
Only `active` nodes with a durable organization cell and accepted host session are eligible for placement.

## Preflight

- `GET /cloud/preflights` lists account and region preflight evidence.
- `POST /cloud/preflights` runs server-side account or region verification and records immutable evidence.

Preflight and host acceptance are different gates.
Preflight validates AWS or GCP identity, real provider API access, zone and machine availability, configured network and image references, and the immutable artifact contract before launch.
Host acceptance validates the actual launched machine and promoted MIOSA runtime before placement.
Sandbox, Computer, and Deployment placement are certified separately because one working runtime does not prove another workload contract.

## SDK

```typescript
const result = await miosa.cloud.provisionPool(poolId, 1);
const nodes = await miosa.cloud.listNodes({ cloudPoolId: poolId });
```

```python
result = client.cloud.provision_pool(pool_id, count=1)
nodes = client.cloud.list_nodes(cloud_pool_id=pool_id)
```

Sandbox creation does not take a pool ID.
An active BYOC organization is automatically and exclusively placed into its configured scheduling cell.

# Computers API

URL: https://miosa.ai/docs/api-reference/computers
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/computers
Source: src/routes/docs/api-reference/computers/+page.md
Description: API reference for creating, managing, and controlling MIOSA computers  -  full lifecycle, desktop control, files, metrics, and env vars.

Computers are persistent desktop VMs with a Linux desktop, streamed desktop access, and APIs for exec, files, apps, metrics, and desktop control. Base path: `/api/v1/computers`.

Verbs supported: **GET** (list/get/config), **POST** (create/start/stop/restart/resize), **PATCH** (update), **PUT** (update), **DELETE** (delete).

Selected mutation endpoints (sandbox templates and migration) accept an `Idempotency-Key` header. Use a UUID v4. Repeating the same key within 24 hours returns the original response without re-executing the mutation.

Rate limits vary by key, tenant policy, and endpoint family. Exceeding the limit returns HTTP 429 with a `Retry-After` header; honor it when you back off.

---

## Create a Computer

**`POST /api/v1/computers`**

Creates a new computer and begins provisioning.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `name` | string | Yes | Display name |
| `template_type` | string | Yes | Template (`"miosa-desktop"`) |
| `size` | string | No | `"small"` (4GB/1CPU), `"medium"` (8GB/2CPU), `"large"` (16GB/4CPU). Default: `"small"` |
| `selected_apps` | string[] | No | Applications to install after boot |
| `workspace_id` | UUID | No | Workspace to assign this computer to. Defaults to the tenant's default workspace. |
| `workspace_slug` | string | No | Existing or auto-created workspace slug. |
| `workspace_name` | string | No | Workspace display name if auto-created. |
| `project_id` | UUID | No | Project to assign this computer to. Defaults to the workspace default project. |
| `project_slug` | string | No | Existing or auto-created project slug. |
| `project_name` | string | No | Project display name if auto-created. |
| `external_workspace_id` | string | No | Your own customer/account/workspace ID. |
| `external_user_id` | string | No | Your own end-user ID. |
| `external_project_id` | string | No | Your own project/app/document ID. |
| `agent_runtime_profile_id` | UUID/string | No | Force a specific agent runtime profile for this computer. Alias: `agent_profile_id`. |
| `skip_agent_runtime_profile` | boolean | No | If `true`, do not apply the tenant/workspace default runtime profile. |

If a default agent runtime profile exists for the workspace or tenant and it
applies to computers, MIOSA applies it automatically. Profile env vars are
stored in the encrypted computer env store and synced into the VM after OSA is
healthy. Profile connectors are bound through MIOSA egress as opaque
`miosa-tok-*` placeholder tokens.

### Response  -  `201 Created`

## Credit Pricing

MIOSA prices sandboxes and computers per size: every size has one hourly price, billed per second while the machine runs, and the price does not change with how busy the machine is. Apps and databases are billed on the CPU and memory they use, and never more than the price of their size. One credit always equals one US cent. There are no per-product prices and no plan discounts.

### Size prices

| Size | vCPU | RAM | Price / hour | Always on (730 h) |
|------|------|-----|--------------|-------------------|
| `micro` | 1 | 0.5 GiB | $0.0316 | $23.05 |
| `tiny` | 1 | 1 GiB | $0.0359 | $26.22 |
| `xs` | 1 | 2 GiB | $0.0446 | $32.58 |
| `small` | 2 | 4 GiB | $0.0893 | $65.16 |
| `quad` | 4 | 4 GiB | $0.1437 | $104.90 |
| `medium` | 4 | 8 GiB | $0.1785 | $130.32 |
| `large` | 8 | 16 GiB | $0.3570 | $260.65 |
| `xl` | 16 | 32 GiB | $0.7141 | $521.29 |

A size's price is $0.027216 per vCPU-hour plus $0.0087075 per GiB-hour of RAM, so a shape that is not in the table (for example 2 vCPU / 8 GiB) costs the same formula. `GET /api/v1/pricing` returns every size with `usd_per_hour` and `usd_per_month`.

### Other rates

| Resource | Rate |
|----------|------|
| Disk (running; also volumes) | $0.09 / GiB-month (about 0.0123 credits / GiB-hour) |
| Data at rest (paused disk, snapshots, backups, run artifacts) | $0.018 / GiB-month (about 0.00247 credits / GiB-hour) |
| Object storage (buckets, static sites) | $0.0162 / GiB-month (about 0.00222 credits / GiB-hour) |
| Network egress | 5.4 credits / GB (no free allowance) |
| Builds | Free |
| Optimal tokens | $1.50 / 1M input, $6.00 / 1M output |

**Billing basis.** A sandbox or computer is billed the price of its size, metered per second with a 1-second minimum, and settled against your credit balance on a 5-minute tick. A stopped or paused machine is not billed for compute. Memory and disk are GiB (1024-based).

### Plans

| Plan | Price | Included credits |
|------|-------|------------------|
| Free | $0/month | $1 of usage each month (100 credits) |
| Developer | $20/month | 2,000 credits/month |
| Business | $500/month | 50,000 credits/month |
| Enterprise | $2,000/month | 200,000 credits/month |

Every plan pays the same price for a size. Plans differ only in caps and concurrency, never in price. Free includes $1 of usage each month; add credits any time. Pay only for what you use. See the [pricing page](/pricing) for the live numbers and the cost calculator.

### Credit expiry

Expiry depends on how the credits were granted:

- **Credits you add** do not expire.
- **Recurring plan credits** expire at the start of the UTC day after the 30-day billing period in which they were granted.
- **Promotional credits** (the one-time welcome grant and promo-code redemptions) expire 180 days after they are granted.

The nearest expiry is reported as `credit_expiry_at` on `GET /api/v1/credits/balance`. See [Pricing and limits](/docs/pricing/) for how usage is metered and billed.

# Custom Domains API

URL: https://miosa.ai/docs/api-reference/custom-domains
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/custom-domains
Source: src/routes/docs/api-reference/custom-domains/+page.md
Description: API reference for mapping tenant-owned FQDNs to MIOSA previews with automatic TLS.

Custom domains let you expose MIOSA previews, computers, and deployments under tenant-owned FQDNs. There are four related surfaces:

- **Computer custom domains** map one fully qualified domain, such as `app.yourdomain.com`, to one Computer service.
- **Deployment custom domains** map one fully qualified domain, such as `program.example.net`, to one Deployment.
- **Tenant preview domains** white-label generated preview links for the whole organization. After configuration, sandbox `/expose` responses use URLs such as `https://5173-sbx01j9x.sandbox.example.com`.

MIOSA handles verification and automatic TLS certificate issuance via Caddy on-demand TLS.

Nested base paths: `/api/v1/computers/{id}/domains` and `/api/v1/deployments/{id}/domains`.

Flat frontend-compatible base path: `/api/v1/custom-domains`.

Custom domains must not end in `miosa.ai`  -  that namespace is reserved for platform subdomains. Use a domain you control.

---

## Quick Start
```typescript

const client = new Miosa();

// 1. Register the domain
const domain = await client.domains.register(computerId, {
  domain: 'app.yourcompany.com',
});
console.log(domain.verificationTarget); // e.g. "verify.miosa.ai"

// 2. Add a CNAME record at your DNS provider:
//    app.yourcompany.com → verify.miosa.ai

// 3. Trigger verification
const verified = await client.domains.verify(computerId, domain.id);
console.log(verified.status); // "verified" or "failed"
```
```bash
# Register
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/domains \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain": "app.yourcompany.com"}'
```

---

## Endpoints

| `POST` | `/custom-domains` | Register a domain with `computer_id` or `deployment_id` |
| `DELETE` | `/custom-domains/{id}` | Remove a domain |

### Tenant preview domains

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/tenant/preview-domain` | Read the tenant preview domain |
| `PUT` | `/tenant/preview-domain` | Set the tenant preview domain |
| `DELETE` | `/tenant/preview-domain` | Clear the tenant preview domain |

The preview domain is an organization setting. There is no workspace-level or project-level preview-domain endpoint.

---

## White-label Managed Links

Use a tenant preview domain when generated app/artifact preview URLs should use your organization's domain instead of the MIOSA-managed fallback.
```bash
curl -X PUT https://api.miosa.ai/api/v1/tenant/preview-domain \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"preview_domain":"preview.yourcompany.com"}'
```

Then expose a sandbox port:
```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/expose \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"port":5173}'
```

Response:
```json
{
  "url": "https://5173-sbx01j9x.sandbox.preview.yourcompany.com"
}
```

For a single deployment under its own FQDN (not the shared preview domain), register a deployment custom domain instead:

```bash
curl -X POST https://api.miosa.ai/api/v1/deployments/$DEPLOYMENT_ID/domains \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"program.example.net"}'
```

DNS must delegate wildcard traffic to the MIOSA preview router:

| Record type | Name | Value | Used for |
|---|---|---|---|
| `CNAME` | `*` | `proxy.miosa.ai` | `https://{slug}.{domain}` managed deployment/computer/default preview URLs, and `https://{port}-{slug}.sandbox.{domain}` sandbox port previews |

If no tenant preview domain is configured, MIOSA returns the managed fallback URL for that resource. This fallback remains available even after custom domains are attached.

Exact deployment and computer custom domains always win over the organization-wide preview domain.

**`GET /api/v1/computers/{id}/domains`**

### Response  -  `200 OK`
```json
{
  "data": [
    {
      "id": "...",
      "fqdn": "app.yourcompany.com",
      "status": "active",
      "verified_at": "2026-04-11T01:00:00Z",
      "tls_issued_at": "2026-04-11T01:05:00Z",
      "created_at": "2026-04-11T00:00:00Z"
    }
  ],
  "total": 1
}
```
```bash
curl https://api.miosa.ai/api/v1/computers/{id}/domains \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Verify a Domain

**`POST /api/v1/computers/{id}/domains/{domain_id}/verify`**

Checks that the CNAME record at `fqdn` resolves to `verification_target`. On success the domain transitions to `"verified"` and Caddy will issue a TLS certificate on the next HTTPS request to the FQDN.

### Path Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `id` | UUID | Computer ID |
| `domain_id` | UUID | Domain ID |

### Response  -  `200 OK`
```json
{
  "data": {
    "id": "...",
    "fqdn": "app.yourcompany.com",
    "status": "verified",
    "verified_at": "2026-04-11T01:00:00Z"
  }
}
```

### Errors

| Status | Error | Cause |
|--------|-------|-------|
| 409 | `domain is already verified` | Already completed |
| 422 | `CNAME not found` | DNS record missing or not yet propagated |
```bash
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/domains/{domain_id}/verify \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Remove a Domain

**`DELETE /api/v1/computers/{id}/domains/{domain_id}`**

Detaches the domain from the computer. The certificate is not revoked immediately (Caddy lets it expire naturally), but the domain will no longer route to the computer.

### Response  -  `200 OK`
```json
{
  "data": { "id": "...", "fqdn": "app.yourcompany.com", "status": "removed" }
}
```
```bash
curl -X DELETE https://api.miosa.ai/api/v1/computers/{id}/domains/{domain_id} \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## DNS Setup Reference

After registering a domain, add the following DNS record at your registrar or DNS provider:

| Record | Host | Value |
|--------|------|-------|
| CNAME | `app` (or full subdomain) | `verify.miosa.ai` |

DNS propagation typically takes 1-60 minutes. Call `verify` once propagation is complete. If verification fails, wait a few minutes and retry  -  the endpoint is idempotent.

---

## Common Recipes

### Automate full domain onboarding
```python

from miosa import Miosa

client = Miosa()

domain = client.domains.register(computer_id, fqdn="api.yourcompany.com")
print(f"Add CNAME: {domain.fqdn} → {domain.verification_target}")
print("Waiting for DNS propagation...")

while True:
    result = client.domains.verify(computer_id, domain.id)
    if result.status == "verified":
        print("Domain verified! TLS will be issued on first HTTPS request.")
        break
    elif result.status == "failed":
        raise RuntimeError("Verification failed  -  check your DNS records.")
    time.sleep(30)
```

### List all pending domains (potential stuck ACME issuances)
```typescript
const computers = await client.computers.list();
for (const computer of computers.data) {
  const { data: domains } = await client.domains.list(computer.id);
  const pending = domains.filter(d => d.status === 'pending');
  if (pending.length > 0) {
    console.log(`${computer.name}: ${pending.length} domain(s) pending verification`);
  }
}
```

# Databases API

URL: https://miosa.ai/docs/api-reference/databases
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/databases
Source: src/routes/docs/api-reference/databases/+page.md
Description: Provision and operate managed databases, backups, restores, branches, replicas, credentials, and placement.

Managed databases have a lifecycle independent from sandboxes and deployment runtime instances.
Deleting or replacing compute does not implicitly delete an attached database.

Base path: `/api/v1/databases`

The `managed-databases` alias is not available: use `/api/v1/databases`.

## Core lifecycle

| Method | Path | Purpose |
|---|---|---|
| `GET` | `/databases` | List databases visible to the current tenant and workspace scope |
| `POST` | `/databases` | Create a managed database |
| `GET` | `/databases/{id}` | Inspect one database |
| `DELETE` | `/databases/{id}` | Permanently delete one database |
| `POST` | `/databases/{id}/start` | Start a stopped or recoverable database |
| `POST` | `/databases/{id}/stop` | Stop a running database while preserving its volume |
| `POST` | `/databases/{id}/restart` | Restart the database runtime |
| `POST` | `/databases/{id}/wake` | Wake a database that can be resumed |
| `POST` | `/databases/{id}/resize-compute` | Change its compute allocation |
| `POST` | `/databases/{id}/move` | Move the database through the managed placement workflow |

## Data topology and recovery

| Method | Path | Purpose |
|---|---|---|
| `POST` | `/databases/{id}/branch` | Create an independent database branch |
| `POST` | `/databases/{id}/replicas` | Create a replica |
| `POST` | `/databases/{id}/backups` | Create an on-demand backup |
| `GET` | `/databases/{id}/backups` | List backups |
| `GET` | `/databases/{id}/backups/{backup_id}` | Inspect one backup |
| `POST` | `/databases/{id}/restore` | Restore from a selected backup |
| `GET` | `/databases/{id}/restores` | List restore operations |
| `GET` | `/databases/{id}/credentials` | Return the current connection contract |

Logs and metrics use the common observability endpoints:

```http
GET /api/v1/databases/{id}/logs
GET /api/v1/databases/{id}/logs/stream
GET /api/v1/databases/{id}/metrics
```

## Create

```bash
curl -X POST https://api.miosa.ai/api/v1/databases \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"app-production","engine":"postgresql"}'
```

Creation is asynchronous.
Wait until the returned database reaches `running` before connecting.

```bash
miosa api POST /databases -d '{"name":"app-production","engine":"postgresql"}'
```

## Credentials

```bash
curl https://api.miosa.ai/api/v1/databases/$DATABASE_ID/credentials \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Use the returned recommended connection URL.
Do not construct hostnames, ports, usernames, or database names from resource metadata.

## Backup and restore

```bash
miosa db backup <database-id> --json
miosa api POST /databases/<database-id>/restore \
  -d '{"backup_id": "<backup-id>", "allow_overwrite": true}'
```

Restore replaces the target database contents with the selected backup.
Confirm the database ID and backup ID before approving the operation.

Database restore does not change the active application release.
Application rollback does not reverse database migrations.
Use backward-compatible expand, migrate, and contract changes when releases must remain rollback-safe.

## Permissions

| Action | Required scope |
|---|---|
| List, inspect, read metrics, or fetch credentials | `databases:read` |
| Create, resize, branch, back up, restore, move, or delete | `databases:write` |

# Desktop API

URL: https://miosa.ai/docs/api-reference/desktop
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/desktop
Source: src/routes/docs/api-reference/desktop/+page.md
Description: API reference for all desktop control endpoints  -  screenshot, mouse, keyboard, clipboard, windows, accessibility tree.

Desktop control endpoints proxy commands to the computer command service inside the computer VM via the MIOSA control plane. All coordinates are in screen pixels (0,0 = top-left).

Base path: `/api/v1/computers/{id}/desktop`

All desktop endpoints require the computer to be in `"running"` status. Returns `409 COMPUTER_NOT_RUNNING` if the computer is stopped or provisioning.

Rate limits vary by key, tenant policy, and endpoint family. Honor `X-RateLimit-*` and `Retry-After` response headers. Individual desktop actions are fast but high-frequency AI agents should batch operations where possible.

# API Reference / Docker Host

URL: https://miosa.ai/docs/api-reference/docker-deploy
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/docker-deploy
Source: src/routes/docs/api-reference/docker-deploy/+page.md
Description: REST API for Docker Host templates, workspace hosts, and sandbox-to-container publishing.

Docker Host is the dedicated workspace host for customers who need many containerized apps on one always-on MIOSA-managed runtime.

Use the regular Deployments API for the deployment object.
Use the Docker Host API to choose templates and provision the workspace host.

Docker Host apps still return normal MIOSA deployment URLs and custom-domain records.
The workspace host runs the app containers while MIOSA owns DNS, TLS, routing, health checks, and deployment records.

## Endpoints

```http
GET  /api/v1/docker-deploy/templates
GET  /api/v1/docker-deploy/templates/:id
GET  /api/v1/docker-deploy/hosts?workspace_id=:workspace_id
POST /api/v1/docker-deploy/hosts/ensure
GET  /api/v1/docker-deploy/hosts/:id

POST /api/v1/sandboxes/:id/publish
POST /api/v1/deployments/:id/publish
```

All endpoints require `Authorization: Bearer <msk_*>`. Mutations should include an `Idempotency-Key` header.

## List templates

```http
GET /api/v1/docker-deploy/templates
```

Returns curated container deployment templates such as Next.js app, Next.js static site, React/Vite, static HTML, Python API, Node API, and compose-backed app patterns.

Response:

```json
{
  "data": [
    {
      "id": "nextjs-app",
      "name": "Next.js App",
      "runtime": "node",
      "build_command": "npm install && npm run build",
      "run_command": "npm start",
      "port": 3000,
      "health_check_path": "/"
    }
  ]
}
```

## Get template

```http
GET /api/v1/docker-deploy/templates/:id
```

Use this when your UI needs the template defaults before creating or publishing a deployment.

## List workspace hosts

```http
GET /api/v1/docker-deploy/hosts?workspace_id=550e8400-e29b-41d4-a716-446655440000
```

Returns Docker Host hosts visible to the caller.

Response:

```json
{
  "data": [
    {
      "id": "78745c76-d5e6-4541-b651-1018f7cc0d89",
      "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
      "computer_id": "cmp_...",
      "status": "active",
      "runtime_status": "healthy",
      "runtime_version": "2026.07"
    }
  ]
}
```

## Ensure workspace host

```http
POST /api/v1/docker-deploy/hosts/ensure
```

Creates or returns the dedicated Docker Host host for a workspace.
One host can run many deployments for that workspace.

Body:

```json
{
  "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
  "region": "us-central",
  "size": "standard",
  "metadata": {
    "customer": "Lumen"
  }
}
```

Response:

```json
{
  "data": {
    "id": "78745c76-d5e6-4541-b651-1018f7cc0d89",
    "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
    "computer_id": "cmp_...",
    "status": "provisioning",
    "runtime_status": "booting"
  }
}
```

## Get host

```http
GET /api/v1/docker-deploy/hosts/:id
```

Returns the latest status for one Docker Host host.
A deployment is not ready until the host is active and the deployed app health check passes through that host.

## Publish from sandbox

```http
POST /api/v1/sandboxes/:id/publish
```

Body:

```json
{
  "name": "Acme Lead Magnet",
  "deployment_type": "docker_deploy",
  "docker_deploy_template_id": "nextjs-app",
  "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
  "project_id": "660e8400-e29b-41d4-a716-446655440001",
  "build_command": "npm install && npm run build",
  "run_command": "npm start",
  "port": 3000,
  "health_check_path": "/",
  "external_workspace_id": "acct_123",
  "external_project_id": "lead_magnet_456"
}
```

MIOSA packages the sandbox, ensures the workspace Docker Host host exists, installs the release, waits for the app route health check, then returns the deployment and public URL.

## Publish existing deployment

```http
POST /api/v1/deployments/:id/publish
```

Use the same Docker Host fields when publishing a new version of an existing deployment:

```json
{
  "source_sandbox_id": "sbx_...",
  "deployment_type": "docker_deploy",
  "docker_deploy_template_id": "nextjs-app",
  "build_command": "npm install && npm run build",
  "run_command": "npm start",
  "port": 3000,
  "health_check_path": "/"
}
```

# Egress (Security) API

URL: https://miosa.ai/docs/api-reference/egress
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/egress
Source: src/routes/docs/api-reference/egress/+page.md
Description: API reference for the MIOSA Egress credential vault, network allowlist, OAuth Connect, and audit log.

The Egress API powers the **Security** tab on every Computer and Sandbox: encrypted credential vault, OAuth Connect, network allowlist with audit-only / enforce modes, and a live-tail audit log.

Base path: `/api/v1/egress`

All endpoints require `Authorization: Bearer &lt;msk_*&gt;`. See [Authentication](/docs/authentication). For higher-level access, use the [SDKs](/docs/sdks/egress).

For the architecture overview, walkthroughs, and white-label patterns, see the [Security guides](/docs/security).

---

## Secrets

### Create a secret

**`POST /api/v1/egress/secrets`**

Stores an encrypted credential and optionally binds it to a resource as an environment variable. The raw value is encrypted with ChaCha20-Poly1305 and never returned again.

```bash
curl -X POST https://api.miosa.ai/api/v1/egress/secrets \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "openai_key",
    "value": "sk-proj-...",
    "type": "api_key",
    "scope": "user",
    "expose_as_env": "OPENAI_API_KEY"
  }'
```

Required body fields: `name`, `value`, `type`, `scope`.

| Field | Values | Notes |
|---|---|---|
| `type` | `api_key`, `oauth_connect`, `oauth_machine` | OAuth flows are usually initiated via `/oauth/start` instead. |
| `scope` | `tenant`, `workspace`, `user`, `external_user`, `external_workspace` | The 5-tier scoping model. |
| `expose_as_env` | shell-safe upper-snake-case | If set, auto-creates a binding. |

Optional scoping fields based on `scope`: `workspace_id`, `owner_user_id`, `external_user_id`, `external_workspace_id`.

Returns `201 Created` with `{data: <public_secret>, binding: <binding_or_null>}`. The `data.preview` is the first-6 + last-4 of the value; the full value is never returned.

### List secrets

**`GET /api/v1/egress/secrets`**

Query params: `scope`, `workspace_id`, `owner_user_id`, `external_user_id`, `external_workspace_id`.

Returns metadata only (no values).

### Get a secret

**`GET /api/v1/egress/secrets/:id`**  -  metadata for one secret.

### Rotate

**`PATCH /api/v1/egress/secrets/:id`**

Re-encrypts with a new value. The bound `placeholder_token` does not change; every sandbox using it picks up the new value on its next outbound request.

```json
{ "value": "sk-proj-new-value", "expires_at": "2026-12-31T00:00:00Z" }
```

### Delete

**`DELETE /api/v1/egress/secrets/:id`**

---

## Bindings

A binding links a secret to a Computer or Sandbox and surfaces it as an environment variable (or opaque header token).

### Create a binding

**`POST /api/v1/egress/bindings`**

```json
{
  "secret_id": "<uuid>",
  "resource_id": "<computer-or-sandbox-id>",
  "resource_type": "sandbox",
  "exposure": "env_var",
  "expose_as_env": "OPENAI_API_KEY"
}
```

Returns the binding including its `placeholder_token`  -  the opaque `miosa-tok-…` value the workload sees in env.

### List + delete

- `GET /api/v1/egress/bindings?resource_id=<id>&resource_type=sandbox`
- `DELETE /api/v1/egress/bindings/:id`

---

## OAuth Connect

### List provider catalog

**`GET /api/v1/egress/oauth/providers`**  -  returns providers visible to the calling tenant (platform defaults merged with tenant overrides). No client secrets exposed.

### Start an OAuth flow

**`POST /api/v1/egress/oauth/start`**

```json
{
  "provider": "github",
  "expose_as_env": "GITHUB_TOKEN",
  "scope": "user",
  "owner_user_id": "<uuid>"
}
```

Returns `{authorize_url, state}`. Open `authorize_url` in a browser; the user approves; the upstream redirects to `/api/v1/egress/oauth/callback?code=&state=`. On success the tokens are encrypted into a new `oauth_connect` secret + binding.

### Status

**`GET /api/v1/egress/oauth/status?state=<state>`**  -  poll while the user is completing the flow. Returns `pending`, `complete`, or `failed`.

### Admin: tenant-override providers (white-label)

- `POST /api/v1/egress/oauth/admin/providers`  -  register your own OAuth app credentials so end-users see your brand on the consent screen.
- `DELETE /api/v1/egress/oauth/admin/providers/:id`

Requires admin (`msk_a_*`) credentials.

---

## Network policies + allowlist

### Policies

- `GET /api/v1/egress/policies`  -  list (optionally filter by `resource_id`)
- `POST /api/v1/egress/policies`  -  create
- `GET /api/v1/egress/policies/:id`
- `PATCH /api/v1/egress/policies/:id`  -  set `mode` (`audit_only` / `enforce`), `default_action` (`allow` / `deny`)

Each Computer or Sandbox resolves the policy in this order: resource override → tenant default. Tenant default starts in `audit_only` mode.

### Allowlist rules

- `GET /api/v1/egress/allowlist?policy_id=<uuid>`
- `POST /api/v1/egress/allowlist`
- `DELETE /api/v1/egress/allowlist/:id`

```json
{
  "policy_id": "<uuid>",
  "pattern": "*.openai.com",
  "kind": "wildcard",
  "method": "POST",
  "path_glob": "/v1/*",
  "action": "allow",
  "warn_only": false,
  "priority": 100
}
```

Pattern kinds: `exact` (literal host), `wildcard` (`*.example.com`), `cidr` (IP literal targets only).

---

## Audit log

### Query

**`GET /api/v1/egress/audit`**

Query params: `resource_id`, `host`, `action` (`allow`/`reject`/`stub`/`error`), `since` (relative like `1h` / `7d` or ISO timestamp), `until`, `limit` (default 100, max 1000), `external_user_id`, `external_workspace_id`.

Each row includes the full identity chain (`tenant_id`, `workspace_id`, `owner_user_id`, `external_user_id`, `external_workspace_id`), request metadata (`host`, `method`, `path`, `sni`, `mode`, `remote_addr`), outcome (`action`, `rejected_by`, `status_code`, `duration_ms`, `bytes_in`, `bytes_out`, `error_message`), and the transform trace JSONB (`request_transforms`, `response_transforms`, `mcp`).

### Get a single event

**`GET /api/v1/egress/audit/:id`**

### Allowlist suggestions

**`GET /api/v1/egress/audit/suggestions?resource_id=<id>`**  -  returns the hosts a resource has contacted recently, ranked by frequency. The basis for the one-click "Lock down with selected as allowlist" UX.

### Live tail (WebSocket)

**`wss://api.miosa.ai/api/v1/egress/audit/resource/:resource_id?token=<jwt>`**

Subprotocol: `miosa-egress-audit-v1`. Intended to push `{"type":"audit_event","data":{...}}` frames in real time as outbound requests are recorded. Egress audit capture is not yet enabled in the current release, so no frames are emitted yet.

Tenant-scoped variant (admin only): `wss://api.miosa.ai/api/v1/egress/audit/tenant/:tenant_id?token=<jwt>`.

---

## Rate limits + retention

| Scope | Limit |
|---|---|
| All `/egress/*` endpoints | Current limit is returned through `X-RateLimit-*` headers |
| Audit retention | 90 days for every tenant; longer on enterprise |
| Audit live-tail (WebSocket) | unlimited; does not count against REST quota |

---

## Errors

Same envelope as the rest of the API  -  `{"error": "...", "details": ...}` with the appropriate status code.

| Status | When |
|---|---|
| `400` | invalid body, unknown scope, malformed env var name |
| `401` | missing / invalid credential |
| `403` | role does not allow the operation (e.g., creating tenant-scoped secret as a non-admin) |
| `404` | secret / binding / policy / event not found in this tenant |
| `409` | secret name collision within scope (unique partial index) |
| `422` | scope ↔ identity column mismatch (e.g., scope=user without owner_user_id) |

---

## SDK shortcut

All endpoints above are wrapped by the [Egress SDK reference](/docs/sdks/egress) with idiomatic methods in Python, TypeScript, Go, Java, and Elixir.

# Error Codes

URL: https://miosa.ai/docs/api-reference/errors
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/errors
Source: src/routes/docs/api-reference/errors/+page.md
Description: Every error code the MIOSA API returns, what it means, and how to handle it.

Most MIOSA API errors follow a single envelope shape, `{error: {code, message, request_id}}`. The HTTP status indicates the broad class; the `code` field is the machine-readable reason. A few families differ: authentication failures return a flat `{error: {type, code}}` shape, and snapshot errors can return a flat message string.

```json
{
  "error": {
    "code": "NOT_FOUND",
    "message": "sandbox not found",
    "request_id": "req_01jv..."
  }
}
```

Include `request_id` whenever you contact support. It correlates the request across all internal services.

---

## Authentication errors

Returned by the `ApiKeyAuth` plug before the request reaches any controller.

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `invalid_token` | 401 | `Authorization` header missing, malformed, or the key/JWT is invalid | Verify the header is `Authorization: Bearer msk_...` |
| `invalid_token` | 401 | Refresh token used on a non-auth endpoint | Use a workspace API key (`msk_*`), not a refresh token |
| `insufficient_scope` | 403 | Key exists but lacks the required scope for this operation | Adjust key scopes in the dashboard |
| `RATE_LIMIT_EXCEEDED` | 429 | Too many requests from this key or IP | Back off and retry after `Retry-After` seconds |

All API endpoints are rate-limited.
Limits vary by key family, tenant policy, and endpoint family.
Honor `X-RateLimit-*` and `Retry-After` instead of hardcoding a client-side limit.

---

## General resource errors

These codes appear across all resource types (computers, sandboxes, deployments, workspaces, etc.).

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `NOT_FOUND` | 404 | Resource does not exist or belongs to a different tenant | Confirm the ID and that the key's tenant owns the resource |
| `FORBIDDEN` | 403 | Authenticated but not authorized to access this resource | Check membership or ownership |
| `INVALID_ID` | 400 | Path parameter is not a valid UUID | Use a UUID v4 ID, not a slug or name |
| `MISSING_PARAM` | 400 | A required request body field is absent | Check the field name in the request body schema |
| `VALIDATION_ERROR` | 422 | One or more fields failed schema validation | Inspect `details` for per-field messages |
| `VALIDATION_FAILED` | 422 | Changeset validation failed (alias of `VALIDATION_ERROR` in some controllers) | Inspect `details` |
| `TENANT_RESOLUTION_FAILED` | 422 | Cannot determine the tenant for the authenticated identity | The API key may belong to a workspace that has been deleted or suspended |
| `INTERNAL_ERROR` | 500 | Unexpected server-side error | Retry with exponential backoff; report if persistent |

---

## Sandbox errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `INSUFFICIENT_CREDITS` | 402 | Not enough credits to provision this sandbox | Top up credits in the dashboard or reduce the resource request |
| `SANDBOX_LIMIT_REACHED` | 429 | Tenant has hit the concurrent sandbox cap for its plan (Developer 10, Business 250, Enterprise 500) | Destroy idle sandboxes, upgrade the plan, or contact support to raise the limit |
| `SANDBOX_NOT_RUNNING` | 409 | Operation requires the sandbox to be in `running` state | Wait until state is `running`; poll `GET /sandboxes/{id}` or subscribe to events |
| `AGENT_UNAVAILABLE` | 502 | The computer command service is reachable but not responding | Wait and retry; if persistent, destroy and recreate the sandbox |
| `INVALID_TEMPLATE` | 400 | `template_id` is not a recognized template | Use `GET /api/v1/sandbox-templates` to list valid IDs |
| `MISSING_PATH` | 400 | `path` field is required but absent | Include `path` in the request body |
| `INVALID_PATH` | 400 | `path` is not a valid absolute filesystem path | Use an absolute path (starts with `/`) |
| `MISSING_FILE` | 400 | Multipart upload missing the `file` part | Include the file part in the multipart form |
| `INVALID_BODY` | 400 | Request body could not be parsed or decoded | Verify JSON or base64 encoding |
| `MISSING_MODE` | 400 | `chmod` call missing `mode` field | Include an octal mode string, e.g. `"0644"` |
| `INVALID_PORT` | 422 | Expose port is outside `1`-`65535` | Use a port in the valid range |
| `MISSING_PARAM` | 400 | `port` omitted on `/expose` and template has no default preview port | Provide `port` explicitly |
| `SANDBOX_NOT_RUNNING` | 409 | `/deploy` called but sandbox is not running | Confirm sandbox state before promoting |
| `SANDBOX_PLACEMENT_UNCERTAIN` | 409 | A create without an `Idempotency-Key` could not confirm its placement outcome, so the sandbox may or may not exist | List your sandboxes to reconcile before creating another; retrying without a key risks a duplicate |
| `SANDBOX_PLACEMENT_RECONCILING` | 503 | A create that carried an `Idempotency-Key` could not confirm its placement outcome yet | Retry with the same `Idempotency-Key` after `Retry-After` seconds; the retry resolves to the same sandbox |
| `INVALID_SANDBOX_RUNTIME_PROFILE` | 422 | `runtime_profile` is not `standard`, `soma`, or `auto` | Send one of the allowed values; `details.allowed` names them |
| `SOMA_RUNTIME_UNSUPPORTED_REQUEST` | 422 | The requested shape is above the runtime's maximum, or the runtime cannot serve it | Request a smaller shape, or use `runtime_profile "standard"`; `details.max_shape` names the ceiling |

When a sandbox create cannot confirm its placement outcome, the answer depends on whether you sent an `Idempotency-Key` header.

- With a key, the API returns a retryable `503 SANDBOX_PLACEMENT_RECONCILING` with `Retry-After`. Retry with the same key and it resolves to the same sandbox.
- Without a key, the API returns a terminal `409 SANDBOX_PLACEMENT_UNCERTAIN`. List your sandboxes to reconcile before creating another, since a retry could create a duplicate.

Send an `Idempotency-Key` on every create so an uncertain outcome is retryable instead of terminal.

---

## Sandbox template build errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `TEMPLATE_NOT_FOUND` | 404 | Template ID does not exist | Verify the template ID |
| `BUILD_NOT_FOUND` | 404 | Build record does not exist | Verify the build ID |
| `BUILD_ALREADY_TERMINAL` | 409 | Cannot cancel a build that is already `ready`, `failed`, or `cancelled` | No action needed; build is in a terminal state |
| `BUILD_NOT_RETRYABLE` | 409 | Build is not in a state that allows retry (`failed` or `cancelled` only) | Only `failed` or `cancelled` builds may be retried |
| `UNAUTHORIZED` | 401 | SSE ticket missing, invalid, or expired | Re-issue a ticket via `POST /auth/sse-ticket` and reconnect |

---

## Computer errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `INSUFFICIENT_CREDITS` | 402 | Not enough credits to start this computer | Top up credits |
| `COMPUTER_NOT_RUNNING` | 409 | Desktop or exec operation requires a running computer | Start the computer first |
| `COMPUTER_NOT_FOUND` | 404 | Computer does not exist in this tenant | Verify the computer ID |
| `AGENT_UNAVAILABLE` | 502 | computer command service unreachable | Computer may be starting; retry after a few seconds |

---

## Deployment errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `DEPLOYMENT_NOT_FOUND` | 404 | Deployment ID does not exist | Verify the deployment ID |
| `VALIDATION_ERROR` | 422 | Deployment fields failed validation | Check `details` for field-level messages |
| `SANDBOX_NOT_RUNNING` | 409 | Publishing requires a running sandbox | Confirm sandbox state |
| `RUNTIME_TARGET_UNAVAILABLE` | 409 | Sandbox has no IP yet  -  cannot route to it | Retry after a few seconds |
| `RUNTIME_LOGS_UNAVAILABLE` | 502 | Cannot fetch runtime logs from the sandbox | Retry or check sandbox health |
| `EMPTY_ARTIFACT` | 422 | Publish output contained no files | Verify your build step produces output files |
| `SERVICE_UNAVAILABLE` | 503 | A required internal service (e.g. encryption) is not configured | Contact support |

---

## Snapshot errors

Direct snapshot create, list, restore, and delete operations apply to desktop Computers under `/api/v1/computers/{id}/snapshots`.
Canonical sandbox V1 exposes snapshot-backed fork at `/api/v1/sandboxes/{id}/fork`, not customer-managed snapshot IDs.

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `NOT_FOUND` (snapshot) | 404 | Snapshot does not exist or belongs to a different computer | Verify snapshot ID and computer ID |
| `FORBIDDEN` | 403 | Authenticated tenant does not own this snapshot | Check ownership |
| `already_deleted` | 409 | Snapshot has already been deleted | No action; already in terminal state |
| `snapshot is not in ready state` | 409 | Restore attempted before snapshot reached `ready` | Poll snapshot status until `ready` |
| `missing sse ticket` | 401 | SSE stream opened without a ticket | Issue a ticket via `POST /auth/sse-ticket` first |

---

## Custom domain errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `DOMAIN_NOT_FOUND` | 404 | Custom domain record not found | Verify the domain ID |
| `COMPUTER_NOT_FOUND` | 404 | The computer this domain is attached to was not found | Verify the computer ID |
| `FORBIDDEN` | 403 | Domain belongs to a different tenant | Verify ownership |
| `VALIDATION_FAILED` | 422 | `fqdn` missing or invalid | Include a valid fully-qualified domain name |

---

## Workspace errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `VALIDATION_FAILED` | 422 | Workspace creation or update fields are invalid | Inspect `details` |
| `TEMPLATE_NAME_TAKEN` | 409 | A template with that name already exists in this workspace | Choose a different name |

---

## Rate-limit and quota errors

| Code | HTTP | Meaning | What to do |
|---|---|---|---|
| `RATE_LIMIT_EXCEEDED` | 429 | General API rate limit hit | Respect the `Retry-After` response header |
| `SANDBOX_LIMIT_REACHED` | 429 | Concurrent sandbox cap reached | Destroy idle sandboxes or upgrade plan |
| `INSUFFICIENT_CREDITS` | 402 | Credit balance depleted | Purchase credits from the billing dashboard |

All 429 responses include a `Retry-After` header (seconds). Honor it  -  repeated violations may result in temporary IP blocks.

# Events (SSE)

URL: https://miosa.ai/docs/api-reference/events
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/events
Source: src/routes/docs/api-reference/events/+page.md
Description: Server-Sent Event streams for real-time updates from sandboxes, computers, deployments, and builds.

MIOSA exposes SSE streams for resources that produce timed events: sandboxes, computer sessions, deployment builds, sandbox-template builds, and computer logs. All streams follow the same authentication and envelope pattern.

---

## Authentication pattern

The browser `EventSource` API cannot send an `Authorization` header. Use the two-step ticket flow for all SSE connections:
Diagram:
sequenceDiagram
  participant Client
  participant MIOSA API
  Client->>MIOSA API: POST /api/v1/auth/sse-ticket<br/>Authorization: Bearer msk_u_...
  MIOSA API-->>Client: { "ticket": "sset_..." }
  Client->>MIOSA API: GET <stream-endpoint>?ticket=sset_...<br/>Accept: text/event-stream
  MIOSA API-->>Client: text/event-stream (open connection)

**Step 1  -  Mint a ticket:**
```bash
curl -X POST https://api.miosa.ai/api/v1/auth/sse-ticket \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json"
# Response: { "ticket": "sset_01hx9z...", "expires_in": 60 }
```

Tickets are single-use and expire in 60 seconds. Mint one immediately before opening the `EventSource`.

**Step 2  -  Open the stream:**
```bash
curl -N "https://api.miosa.ai/api/v1/sandboxes/{id}/events?ticket=sset_01hx9z..." \
  -H "Accept: text/event-stream"
```

---

## Live SSE streams

| Stream | Endpoint | Description |
|---|---|---|
| Sandbox events | `GET /sandboxes/{id}/events` | Exec progress, file change notifications, preview readiness |
| Computer agent events | `GET /computers/{id}/agent/events` | Agent task progress and computer lifecycle |
| Computer logs | `GET /computers/{id}/logs/stream` | stdout/stderr from computer processes |
| Sandbox logs | `GET /sandboxes/{id}/logs/stream` | stdout/stderr from sandbox template lifecycle |
| Build events | `GET /sandbox-template-builds/{id}/logs/stream` | Custom template build progress |

---

## Event envelope

All events arrive in standard SSE format:
```

event: <event_type>
data:
id: <monotonic ULID>
```

All payloads are JSON. The `id:` line allows clients to resume with `Last-Event-ID` on reconnect.

---

## Sandbox event types

| Event | Payload | Description |
|---|---|---|
| `sandbox.started` | `{sandbox_id, region}` | Boot complete; ready to accept exec |
| `sandbox.exec.started` | `{exec_id, command}` | Command began |
| `sandbox.exec.stdout` | `{exec_id, line}` | stdout chunk |
| `sandbox.exec.stderr` | `{exec_id, line}` | stderr chunk |
| `sandbox.exec.completed` | `{exec_id, exit_code, duration_ms}` | Command exited |
| `sandbox.preview.ready` | `{preview_id, url, port}` | Preview URL available |
| `sandbox.idle` | `{sandbox_id, last_activity_at}` | Going to auto-suspend |
| `sandbox.suspended` | `{sandbox_id}` | Auto-suspended after idle window |

---

## Deployment event types

| Event | Payload | Description |
|---|---|---|
| `deployment.publish.queued` | `{version_id}` | Publish accepted, waiting for builder |
| `deployment.publish.building` | `{version_id, stage}` | Builder running |
| `deployment.publish.uploading` | `{version_id, size_bytes}` | Release artifact upload |
| `deployment.publish.promoting` | `{version_id}` | Switching active version |
| `deployment.publish.completed` | `{version_id, deployment_id, url}` | Live |
| `deployment.publish.failed` | `{version_id, error_code, message}` | Build or health-check failure |

---

## Computer event types

| Event | Payload | Description |
|---|---|---|
| `computer.started` | `{computer_id, region}` | VM booted, desktop ready |
| `computer.stream.token_ready` | `{token, expires_at}` | New short-lived stream credential |
| `computer.idle` | `{computer_id, idle_seconds}` | Approaching auto-stop |
| `computer.stopped` | `{computer_id, reason}` | Stopped (manual or auto) |

---

## Reconnect and replay

Send `Last-Event-ID: &lt;ULID&gt;` on the resubscribe request. The server replays all events since that ID. Events are retained for **15 minutes** per resource.
```bash
curl -N "https://api.miosa.ai/api/v1/sandboxes/{id}/events?ticket=sset_..." \
  -H "Accept: text/event-stream" \
  -H "Last-Event-ID: 01hwqz4b3c2v1x..."
```

---

## Error handling

If the connection drops or the ticket expires, the next request returns `401`. Mint a fresh ticket and resubscribe:
```typescript
async function openStream(sandboxId: string): Promise<void> {
  const { ticket } = await fetch('/api/v1/auth/sse-ticket', {
    method: 'POST',
    headers: { Authorization: `Bearer ${process.env.MIOSA_API_KEY}` },
  }).then(r => r.json());

  const es = new EventSource(
    `https://api.miosa.ai/api/v1/sandboxes/${sandboxId}/events/stream?ticket=${ticket}`
  );

  es.addEventListener('error', () => {
    es.close();
    setTimeout(() => openStream(sandboxId), 1000);
  });

  es.addEventListener('sandbox.exec.completed', (e) => {
    console.log('Exec done:', JSON.parse(e.data));
  });
}
```

## Sandbox events stream

**`GET /api/v1/sandboxes/{id}/events`**

Opens a Server-Sent Events (SSE) stream that emits sandbox lifecycle events. The connection closes automatically when the sandbox reaches `destroyed` or `error`.

### Auth

Bearer token required (sent as `Authorization: Bearer &lt;key&gt;` header).

### Path Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `id` | string | Sandbox ID. |

### Response  -  `200 OK` (event stream)

`Content-Type: text/event-stream`

**Event: `state_changed`**
```

event: state_changed
data: {"state":"running","previous_state":"provisioning","timestamp":"2026-04-25T10:00:07Z"}
```

**Event: `exec_output`**
```

event: exec_output
data: {"exec_id":"exec_abc","stream":"stdout","data":"2\n","timestamp":"2026-04-25T10:00:10Z"}
```

**Event: `error`**
```

event: error
data: {"message":"VM terminated unexpectedly","timestamp":"2026-04-25T10:05:00Z"}
```
```bash
curl -N "https://api.miosa.ai/api/v1/sandboxes/sbx_01j9xr2t4fk8me3n5q/events" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Accept: text/event-stream"

# Exec API

URL: https://miosa.ai/docs/api-reference/exec
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/exec
Source: src/routes/docs/api-reference/exec/+page.md
Description: API reference for executing bash commands and Python code on MIOSA computers.

Run commands and scripts directly on a computer without desktop interaction. Both endpoints block until the command exits and return combined stdout+stderr.

Base path: `/api/v1/computers/{id}/exec`

The computer must be in `"running"` status. Commands run as the default user inside the VM. The bash exec timeout is capped at 86,400 s; the Python exec timeout is capped at 300 s.

Rate limits vary by key, tenant policy, and endpoint family. Honor `X-RateLimit-*` and `Retry-After` response headers. For long-running output, prefer the streaming exec endpoint which avoids holding an HTTP connection open for the full duration.

---

## Execute Bash Command

**`POST /api/v1/computers/{id}/exec`**

Runs a shell command on the computer.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `command` | string | Yes | Shell command to execute |
| `timeout` | integer | No | Timeout in seconds (default: 30, max: 86400) |

### Response  -  `200 OK`
```json
{
  "output": "total 24\ndrwxr-xr-x 6 user user 4096 Apr 11 10:00 .\n",
  "exit_code": 0
}
```

The `output` field contains combined stdout and stderr.

### Errors

| Status | Code | Description |
|--------|------|-------------|
| 409 | `COMPUTER_NOT_RUNNING` | Computer is not running |
| 502 |  -  | In-VM agent unreachable |
```bash
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/exec \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "ls -la /workspace", "timeout": 30}'
```

### Examples
```bash
# Install a package
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/exec \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "sudo apt-get install -y jq", "timeout": 120}'

# Check disk space
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/exec \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "df -h"}'

# Multi-line script
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/exec \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "cd /workspace && mkdir -p project && echo done"}'
```

---

## Execute Python Code

**`POST /api/v1/computers/{id}/exec/python`**

Runs Python code on the computer. The code is written to a temporary file and executed with `python3`.

### Request Body

|-------|------|----------|-------------|
| `code` | string | Yes | Python source code |
| `timeout` | integer | No | Timeout in seconds (default: 30, max: 300) |

### Response  -  `200 OK`
```json
{
  "output": "42\n",
  "exit_code": 0
}
```

### How It Works

1. Code is written to `/tmp/miosa_exec_&lt;random&gt;.py`
2. Executed via `timeout &lt;N&gt; python3 /tmp/miosa_exec_&lt;random&gt;.py 2&gt;&1`
3. Temporary file is deleted after execution
4. stdout and stderr are captured in `output`

### Errors

  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "code": "import os\nfor f in os.listdir(\"/workspace\"):\n    print(f)",
    "timeout": 10
  }'

# Long-running computation
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/exec/python \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "code": "total = sum(range(10_000_000))\nprint(f\"Sum: {total}\")",

  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"cols": 120, "rows": 40}'
```

---

## Timeout Behavior

- Commands exceeding the timeout are killed with SIGTERM
- The bash exec timeout is capped at **86,400 seconds**
- The Python exec timeout is clamped: `min(requested, 300)`
- If no timeout is specified, the default is **30 seconds**

## Pre-installed Software

The default template includes:

- Python 3 with pip
- Node.js (if installed via selected_apps)
- Common CLI tools: curl, wget, git, vim, jq
- System utilities: htop, tree, zip/unzip

Install additional packages via the bash exec endpoint:
```bash
# Python packages
{"command": "pip install requests pandas numpy"}

# System packages
{"command": "sudo apt-get install -y postgresql-client"}
```

---

---

## Sandbox exec

The same exec surface exists for sandboxes under `/api/v1/sandboxes/{id}`.

On a SOMA sandbox the executable and each argument are limited to 4096 bytes, and a longer shell command answers `502 AGENT_UNAVAILABLE`, which looks retryable but is not.
Send the command as a file, or on standard input, instead.
See [Choosing a runtime](/docs/soma/choosing-a-runtime/).

### Execute a Command (sandbox)

**`POST /api/v1/sandboxes/{id}/exec`**

Runs a shell command inside the sandbox. Blocks until the process exits.

#### Path Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `id` | string | Sandbox ID. Must be in `running` state. |

#### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `command` | string | Yes | Shell command to execute. |
| `timeout` | integer | No | Per-command timeout in seconds. Default `3600`, max `86400`. |
| `cwd` | string | No | Working directory inside the VM. |
| `env` | object | No | Env vars for this invocation only. |

#### Response  -  `200 OK`
```json
{
  "data": {
    "sandbox_id": "sbx_01j9xr2t4fk8me3n5q",
    "stdout": "2\n",
    "stderr": "",
    "exit_code": 0
  }
}
```

#### Errors

| Status | Code | Cause |
|--------|------|-------|
| 409 | `SANDBOX_NOT_RUNNING` | Sandbox is not in `running` state. |
| 504 |  -  | Command timed out. |

  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "python3 -c \"print(1+1)\"", "timeout": 30}'
```

### Open a Terminal Session (sandbox)

**`POST /api/v1/sandboxes/{id}/terminal`**

Creates a PTY session inside a running sandbox and returns a short-lived stream
token for browser WebSocket clients.

#### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `cols` | integer | No | Initial terminal width. Defaults to `80`. |
| `rows` | integer | No | Initial terminal height. Defaults to `24`. |

  "stream_auth": "eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9...",
  "stream_auth_expires_at": "2026-05-13T12:30:00Z"
}
```

Open the WebSocket with:
```text
wss://api.miosa.ai/api/v1/sandboxes/{id}/terminal/stream?session_id={session_id}&cols=120&rows=32&token={stream_auth}
```

Clients should send raw terminal input as binary frames. Resize events are sent
as JSON text frames:
```json
{"type":"resize","cols":120,"rows":32}
```

Delete the session when finished:
```bash
curl -X DELETE https://api.miosa.ai/api/v1/sandboxes/{id}/terminal/{session_id} \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

## Delete a File

**`DELETE /api/v1/computers/{id}/files`**

Removes a file from the computer.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `path` | string | Yes | Full path to the file to delete |

### Response  -  `200 OK`
```json
{
  "success": true,
  "path": "/workspace/old-file.txt"
}
```

### Errors

| Status | Code | Description |
|--------|------|-------------|
| 400 | `MISSING_PATH` | No path in request body |
| 403 | `FORBIDDEN_PATH` | Path outside allowed directories |
| 502 | `AGENT_UNAVAILABLE` | In-VM agent unreachable |

```

---

## Path Security

All paths are validated before execution:

1. **Expansion**  -  `Path.expand` resolves `..`, `~`, and symlinks
2. **Prefix check**  -  Expanded path must start with `/home/user`, `/home/ubuntu`, or `/tmp`
3. **Rejection**  -  Paths outside these prefixes return `403 FORBIDDEN_PATH`

This prevents path traversal attacks. For example, `/workspace/../../etc/passwd` expands to `/etc/passwd` and is rejected.

---

# Filesystem API

URL: https://miosa.ai/docs/api-reference/filesystem
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/filesystem
Source: src/routes/docs/api-reference/filesystem/+page.md
Description: Complete API reference for file and directory operations on MIOSA computers  -  upload, download, stat, mkdir, rename, copy, chmod, and readdir.

The Filesystem API gives you full programmatic access to files and directories inside a running computer. All operations are proxied through the computer command service and restricted to allowed paths.

Base path: `/api/v1/computers/{id}/files`

**Allowed paths:** `/workspace`, `/home`, `/root`, `/tmp`, `/opt`, `/srv`

The computer must be in `"running"` status. Paths outside the allowed prefixes return `403 FORBIDDEN_PATH`.

---

## Quick Start
```typescript

const client = new Miosa();

// Write a file
await client.files.write(computerId, {
  path: '/workspace/hello.py',
  content: 'print("Hello from MIOSA")',
});

// List the directory
const { files } = await client.files.list(computerId, '/workspace');

// Download it back
const content = await client.files.download(computerId, '/workspace/hello.py');
```

## Common Recipes

### Scaffold a project directory
```typescript
// Create structure
await client.files.mkdir(computerId, { path: '/workspace/app/src', recursive: true });
await client.files.mkdir(computerId, { path: '/workspace/app/tests', recursive: true });

// Write files
await client.files.write(computerId, { path: '/workspace/app/src/main.py', content: mainPy });
await client.files.write(computerId, { path: '/workspace/app/requirements.txt', content: reqs });

// Make entrypoint executable
await client.files.chmod(computerId, { path: '/workspace/app/src/main.py', mode: '755' });
```

### Retrieve build artifacts
```python
# List the build output directory
files = client.files.list(computer_id, path="/workspace/app/dist")
for f in files["files"]:
    if f["type"] == "file":
        content = client.files.export(computer_id, path=f"/workspace/app/dist/{f['name']}")
        save_artifact(f["name"], content["content_base64"])
```

---

## Sandbox filesystem

The sandbox primitive exposes the same list and stat operations under `/api/v1/sandboxes/{id}`.

### List Files (sandbox)

**`GET /api/v1/sandboxes/{id}/files?path=/workspace`**

Lists files and directories in a sandbox directory.
```bash
curl "https://api.miosa.ai/api/v1/sandboxes/{id}/files?path=/workspace" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Response:
```json
{
  "data": {
    "path": "/workspace",
    "entries": [
      {"name": "index.html", "path": "/workspace/index.html", "is_dir": false, "size": 128}
    ]
  }
}
```

### Stat a File (sandbox)

**`POST /api/v1/sandboxes/{id}/files/stat`**

Returns metadata for one file or directory.
```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/files/stat \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"path":"/workspace/index.html"}'
```

# Invites API

URL: https://miosa.ai/docs/api-reference/invites
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/invites
Source: src/routes/docs/api-reference/invites/+page.md
Description: API reference for the workspace invite and org invite flows  -  send, list, revoke, preview, and accept email invitations.

MIOSA has two parallel invite flows:

- **Workspace invites**  -  invite a user to a specific workspace. If the email already belongs to an org member, the user is added directly (no email sent). If not, an invite email is dispatched and accepting it creates both the `tenant_members` and `workspace_members` rows atomically.
- **Org invites**  -  invite a user to join the org (tenant) without pre-selecting a workspace. The accept step only creates the `tenant_members` row.

Both flows produce opaque tokens. The `GET /invites/:token` and `GET /workspace-invites/:token` preview endpoints are **public**  -  they can be called without an API key to render a landing page before the user signs in.

Email invite links should point at the MIOSA frontend, not the API host.
Use `https://miosa.ai/invites/{token}` for org invites and `https://miosa.ai/workspace-invites/{token}` for workspace invites.
Legacy `https://miosa.ai/invite/{token}` links redirect to the org invite landing page for compatibility.

---

## Workspace Invite Endpoints

| Method | Path | Auth | Description |
|--------|------|------|-------------|
| `POST` | `/workspaces/{id}/invites` | Required | Send a workspace invite |
| `GET` | `/workspaces/{id}/invites` | Required | List pending invites |
| `DELETE` | `/workspaces/{id}/invites/{invite_id}` | Required | Revoke an invite |
| `GET` | `/workspace-invites/{token}` | None (public) | Preview invite details |
| `POST` | `/workspace-invites/{token}/accept` | Required | Accept the invite |

## Org Invite Endpoints

| Method | Path | Auth | Description |
|--------|------|------|-------------|
| `POST` | `/tenants/{id}/invites` | Required (admin/owner) | Send an org invite |
| `GET` | `/tenants/{id}/invites` | Required (admin/owner) | List pending org invites |
| `DELETE` | `/tenants/{id}/invites/{invite_id}` | Required (admin/owner) | Revoke an org invite |
| `GET` | `/invites/{token}` | None (public) | Preview org invite details |
| `POST` | `/invites/{token}/accept` | Required | Accept the org invite |

---

## Workspace Invite Flow

### Send Workspace Invite

**`POST /api/v1/workspaces/{id}/invites`**

Sends an invite email and returns the invite record. If the `email` already belongs to a tenant member the user is added directly (response `type = "added"`, no email sent).

#### Request Body

| Field | Type | Required | Description |

# Workspace Members API

URL: https://miosa.ai/docs/api-reference/members
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/members
Source: src/routes/docs/api-reference/members/+page.md
Description: API reference for managing workspace member rosters  -  add, remove, and update roles for users inside a workspace.

Workspace members are the user roster for a specific workspace. A user must already be an org member (`tenant_members` row) before they can be added to a workspace. The last `owner` in a workspace cannot be removed until another member is promoted to owner.

Base path: `/api/v1/workspaces/:id/members`

To invite a new user who is not yet an org member, use the [Workspace Invites API](/docs/api-reference/invites) instead. Accepting a workspace invite automatically creates the `tenant_members` row when the user is new to the org.

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/workspaces/{id}/members` | List workspace members |
| `POST` | `/workspaces/{id}/members` | Add an existing org member to the workspace |
| `PATCH` | `/workspaces/{id}/members/{user_id}` | Update a member's role |
| `DELETE` | `/workspaces/{id}/members/{user_id}` | Remove a member |

---

## Roles

| Role | Description |
|------|-------------|
| `owner` | Full admin including transfer and deletion |
| `admin` | Can manage members and resources |
| `member` | Can create and manage resources |
| `viewer` | Read-only access |

---

## List Members

**`GET /api/v1/workspaces/{id}/members`**

Returns all members of the workspace.

### Response  -  `200 OK`

```json
{
  "data": [
    {
      "user_id": "usr_abc123",
      "email": "alice@example.com",
      "name": "Alice",
      "avatar_url": null,
      "role": "owner",
      "joined_at": "2026-05-01T10:00:00Z",

      "added_by": "usr_abc123"
    }
  ]
}
```


```bash
curl https://api.miosa.ai/api/v1/workspaces/{id}/members \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```


```typescript

const client = new Miosa();

const members = await client.workspaceMembers.list('ws-uuid');
console.log(members);
```


```python

client = miosa.Miosa()
members = client.workspace_members.list("ws-uuid")
print(members)

```go

client := miosa.NewClient(os.Getenv("MIOSA_API_KEY"))
members, err := client.WorkspaceMembers.List(ctx, "ws-uuid")
```


```elixir
client = Miosa.client("msk_u_...")
{:ok, members} = Miosa.WorkspaceMembers.list(client, "ws-uuid")
```


```java
MiosaClient miosa = new MiosaClient("msk_u_...");
List<Map<String,Object>> members = miosa.workspaceMembers().list("ws-uuid");
```


---

## Add Member

**`POST /api/v1/workspaces/{id}/members`**

Adds an existing org member to the workspace with the given role.

The user must already hold a `tenant_members` row for this org. If they are not yet an org member, send a workspace invite via `POST /workspaces/{id}/invites` instead  -  accepting the invite creates the org membership atomically.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `user_id` | UUID | Yes | The user's ID  -  must already be a tenant member |
| `role` | string | Yes | `owner`, `admin`, `member`, or `viewer` |

```json
{
  "data": {

# Network Policy API

URL: https://miosa.ai/docs/api-reference/network-policy
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/network-policy
Source: src/routes/docs/api-reference/network-policy/+page.md
Description: API reference for configuring per-computer network access controls on MIOSA computers.

Network policies control what external hosts and ports a computer can reach. Use them to sandbox untrusted workloads, enforce egress restrictions, or prevent AI agents from making unexpected outbound connections.

Base path: `/api/v1/computers/{id}/network-policy`

Network policies apply at the microVM level. Changing a policy takes effect within seconds without restarting the computer.

---

## Quick Start
```typescript

const client = new Miosa();

// Restrict to only allow HTTPS to GitHub and PyPI
await client.networkPolicy.update(computerId, {
  mode: 'allowlist',
  rules: [
    { host: 'github.com',  port: 443, protocol: 'tcp' },
    { host: 'pypi.org',    port: 443, protocol: 'tcp' },
    { host: 'files.pythonhosted.org', port: 443, protocol: 'tcp' },
  ],
});
```
```bash
curl -X PUT https://api.miosa.ai/api/v1/computers/{id}/network-policy \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \

## Common Recipes

### Sandbox an untrusted AI task
```python
# Lock down before running untrusted code
client.network_policy.update(computer_id, mode="isolated")

# Run the task
result = client.exec(computer_id, command="python3 /workspace/untrusted.py")

# Restore after
client.network_policy.delete(computer_id)
```

### Allow only package registries for a build environment
```typescript
const packageHosts = [
  { host: 'registry.npmjs.org', port: 443, protocol: 'tcp' as const },
  { host: 'pypi.org',           port: 443, protocol: 'tcp' as const },
  { host: 'files.pythonhosted.org', port: 443, protocol: 'tcp' as const },
  { host: 'pkg.go.dev',         port: 443, protocol: 'tcp' as const },
  { host: 'proxy.golang.org',   port: 443, protocol: 'tcp' as const },
];

await client.networkPolicy.update(computerId, {
  mode: 'allowlist',
  rules: packageHosts,
});
```

### Block a known malicious IP range
```typescript
await client.networkPolicy.update(computerId, {
  mode: 'denylist',
  rules: [
    { host: '185.220.0.0/16' },
  ],
});
```

# OpenComputers API

URL: https://miosa.ai/docs/api-reference/open-computers
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/open-computers
Source: src/routes/docs/api-reference/open-computers/+page.md
Description: Register and control customer-owned machines, including on-premises servers, via the MIOSA API  -  exec, files, tunnels, AI agents, inference clusters, and secrets.

# OpenComputers API

OpenComputers lets you register physical or virtual machines you already own (Mac, Linux, Windows) and control them through MIOSA's API  -  run commands, manage files, expose HTTP tunnels, dispatch AI agents, build inference clusters, and manage secrets.

Hosts may be on-premises servers, workstations, or existing machines at a hosting provider.
Available operations depend on the installed agent and the host's capabilities.
See [OpenComputers](/docs/opencomputers/) for hardware, connectivity, and data responsibilities.

Base path: `/api/v1/opencomputers`

Verbs supported: **GET** (list/show), **POST** (register/create/exec/dispatch), **PATCH** (update tags/tunnels), **DELETE** (revoke/cancel).

Rate limits vary by key, tenant policy, and endpoint family. Honor `X-RateLimit-*` and `Retry-After` response headers. Exec jobs and agent sessions run asynchronously  -  poll or stream for results rather than holding the connection.

Register the host and follow the generated instructions to connect the supported OpenComputers agent on the target machine. The **host key** returned on registration is shown exactly
once  -  store it securely.

---

## Hosts

### List hosts

**`GET /api/v1/opencomputers/hosts`**

Returns an object with a `hosts` array.
Inspect each host's `id`, `state`, `capabilities`, and `last_heartbeat` before selecting it.
Use the returned ID exactly; examples below use placeholders.

```json
{
  "hosts": [
    {
      "id": "<host-id>",
      "name": "lab-server",
      "state": "active",
      "capabilities": ["exec"],
      "last_heartbeat": "2026-09-08T12:00:00Z"
    }
  ]
}
```

This is an abbreviated response.
A recent heartbeat and a completed operation are stronger evidence of readiness than a host record alone.

---

### Register a host

**`POST /api/v1/opencomputers/hosts`**

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `name` | string | Yes | Display name for the host |
| `region` | string | No | Region label |
| `platform` | string | No | Host operating-system selection |

Registration returns `{ host, host_key, control_url, warning }`.
The `host` object contains the new host ID; `host_key` authenticates the installed agent.
Use your platform API key for REST requests, not the host key.

`host_key` is returned **only once** at registration time. The host agent uses
it to authenticate. Store it immediately  -  it cannot be retrieved later.

---

### Get a host

**`GET /api/v1/opencomputers/hosts/{id}`**

---

### Revoke a host

**`DELETE /api/v1/opencomputers/hosts/{id}`**

Returns `204 No Content`. The host agent will no longer be able to authenticate.

---

### Host event stream (SSE)

**`GET /api/v1/opencomputers/hosts/{id}/events`**

Streams real-time lifecycle events from the host as Server-Sent Events.
```

event: status_change
data: {"type":"status_change","host_id":"host_abc","data":{"status":"online"},"timestamp":"..."}
```

---

## Jobs

Run shell commands on a registered host and retrieve output.

### Run a job

**`POST /api/v1/opencomputers/hosts/{id}/exec`**

| Field | Type | Required | Description |
|---|---|---|---|
| `cmd` | string | Yes | Command to execute |
| `args` | string[] | No | Arguments passed separately |
| `env` | string[] | No | Environment entries in `KEY=VALUE` format |
| `cwd` | string | No | Working directory |
| `timeout_ms` | integer | No | Timeout in milliseconds; default 30000 |
| `stream` | boolean | No | Default `true`: stream SSE; `false`: collect output as JSON |

With `stream: true`, the POST response carries `exec_chunk`, `exec_result`, or `exec_error` events.
Keep the connection open until the terminal result.
With `stream: false`, a completed command returns:

```json
{
  "job_id": "<job-id>",
  "exit_code": 0,
  "stdout": "lab-server\n",
  "stderr": ""
}
```

A timeout or disconnected client is not proof that the process stopped.
Inspect the job and host before retrying an operation with side effects.

### List jobs

**`GET /api/v1/opencomputers/hosts/{id}/jobs`**

---

### Get a job

**`GET /api/v1/opencomputers/hosts/{id}/exec/{job_id}`**

**`GET /api/v1/opencomputers/hosts/{id}/exec/{job_id}/stream`**

Streams stdout/stderr in real time while the job is running.

---

### Cancel a job

**`DELETE /api/v1/opencomputers/hosts/{id}/exec/{job_id}`**

Returns `204 No Content`.

---

# Preview Tokens API

URL: https://miosa.ai/docs/api-reference/preview-tokens
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/preview-tokens
Source: src/routes/docs/api-reference/preview-tokens/+page.md
Description: Generate short-lived signed tokens for iframe embedding without exposing an API key.

Preview tokens (`mp_*`) are short-lived signed credentials that allow you to embed a running sandbox in an `<iframe>` from a third-party frontend without exposing your `msk_*` API key to the browser.

Base path: `/api/v1/sandboxes/{id}/preview-token`

Preview tokens are single-resource. Each token is scoped to the sandbox it was minted for. Tokens expire after at most 24 hours.

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `POST` | `/api/v1/sandboxes/{id}/preview-token` | Mint a preview token |

---

## Mint a Preview Token

**`POST /api/v1/sandboxes/{id}/preview-token`**

Generates a signed preview token tied to the sandbox. The returned `url` is ready to use as an iframe `src`.

### Auth

Requires an API key or JWT with the `previews:write` scope.

```
Authorization: Bearer msk_...
```

### Request Body

| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `expires_in` | integer | No | `3600` | Token TTL in seconds (max `86400`) |
| `scope` | string | No | `"read"` | `"read"` or `"interact"` |

```json
{
  "expires_in": 3600,
  "scope": "read"
}
```

### Response  -  `200 OK`

```json
{
  "token": "mp_eyJhbGciOiJIUzI1NiJ9...",
  "url": "https://sbx-abc123.sandbox.miosa.ai?mt=mp_eyJ...",
  "expires_at": "2026-05-26T04:00:00Z",
  "scope": "read"
}
```

| Field | Type | Description |
|-------|------|-------------|
| `token` | string | Signed preview token (`mp_<base64url>`) |
| `url` | string | Iframe-ready URL with token pre-embedded as `?mt=` query param |
| `expires_at` | string | ISO 8601 expiry timestamp |
| `scope` | string | `"read"` or `"interact"` |

### Scopes

| Scope | Description |
|-------|-------------|
| `read` | View-only. Mouse and keyboard input are blocked. |
| `interact` | Full mouse/keyboard input forwarded into the sandbox. |

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 404 | `sandbox_not_found` | Sandbox does not exist or belongs to a different tenant |
| 403 | `forbidden` | Tenant mismatch |
| 422 | `invalid_scope` | `scope` is not `"read"` or `"interact"` |

---

## Examples

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/preview-token \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{"expires_in": 3600, "scope": "read"}'
```

```python

client = miosa.Miosa()

token = client.sandboxes.preview_token(
    "sbx_abc123",
    expires_in=3600,
    scope="read",
)

print(token.url)  # embed this in your frontend
```

```typescript

const client = new Miosa();

const token = await client.sandboxes.previewToken('sbx_abc123', {
  expiresIn: 3600,
  scope: 'read',
});

// Pass token.url to your frontend  -  safe to expose in the browser
console.log(token.url);
```

---

## Token Format

Preview tokens use the prefix `mp_` followed by a base64url-encoded signed payload. The token is consumed by the sandbox proxy when passed as the `?mt=` query parameter. Do not parse the token body  -  treat it as opaque.

---

## Iframe Embedding

```html
<!-- Read-only embed  -  no API key in the browser -->
<iframe
  src="https://sbx-abc123.sandbox.miosa.ai?mt=mp_eyJ..."
  width="1280"
  height="800"
  allow="clipboard-read; clipboard-write"
></iframe>
```

The token is verified by the sandbox proxy on every request during the token's lifetime. Once it expires, the iframe will show an access-denied page.

# Previews and publish API

URL: https://miosa.ai/docs/api-reference/previews
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/previews
Source: src/routes/docs/api-reference/previews/+page.md
Description: Expose a sandbox port as a preview URL, publish a sandbox to a stable deployment, and promote a running sandbox to a deployment route.

# Previews and publish

Base path: `/api/v1/sandboxes/{id}`

For preview token minting (embedding a sandbox in an iframe without an API key), see the [Preview Tokens API](/docs/api-reference/preview-tokens/).

## Expose a Preview Port

**`POST /api/v1/sandboxes/{id}/expose`**

Returns a public, tenant-aware preview URL for a server running inside the sandbox. Use this when an agent generated a Vite/Next/FastAPI/Flask app and started it on a local port.

Inside the sandbox, bind dev servers to `0.0.0.0`, not `localhost`:
```bash
npm run dev -- --host 0.0.0.0 --port 5173
python -m http.server 8000 --bind 0.0.0.0
```

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `port` | integer | No | Port inside the sandbox to expose. If omitted, MIOSA uses the template lifecycle preview port when available. Must be `1` through `65535` when provided. |

### Response  -  `200 OK`
```json
{
  "url": "https://5173-sbx01j9x.sandbox.miosa.ai"
}
```

If the tenant has a white-label preview domain configured, the same endpoint returns that domain instead of the platform default. Default app ports such as `3000`, `5173`, `8080`, `8000`, and `80` may be returned as `https://{slug}.sandbox.{domain}`; non-default ports use `https://{port}-{slug}.sandbox.{domain}`.

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 400 | `MISSING_PARAM` | `port` was omitted and the sandbox template has no default preview port. |
| 409 | `SANDBOX_NOT_RUNNING` | Sandbox is not in `running` state. |
| 422 | `INVALID_PORT` | Port is outside `1` through `65535`. |
```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_01j9xr2t4fk8me3n5q/expose \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"port": 5173}'
```

For static artifacts such as PDFs, images, Markdown, CSV, or ZIP files, write them under `/workspace` and download them through the files API. For web apps, start a server and expose the port.

---

## Publish a Sandbox

**`POST /api/v1/sandboxes/{id}/publish`**

Freezes sandbox source, creates an immutable release and deployment version, verifies the candidate, and promotes it behind a stable deployment URL.
Use this endpoint for production publishing.

The CLI is the recommended happy path:

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name <deployment> \
  --type docker_deploy \
  --wait \
  --json
```

Use the same `--name` on every publish so MIOSA preserves the deployment ID and canonical URL.

See [Publishing](/docs/docker-host/publishing/) for request options, proof, and failure behavior.

## Promote a Sandbox Runtime to a Deployment

**`POST /api/v1/sandboxes/{id}/deploy`**

This compatibility bridge routes a persistent deployment URL directly to a running sandbox.
The sandbox remains the runtime behind the route and its auto-destroy timer is cancelled.

Use it only when the sandbox itself must remain the runtime.
For immutable production versions and Docker Host, use `/publish`.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `name` | string | Yes | Human-readable deployment name. Used to create the deployment slug. |
| `port` | integer | No | Runtime port to route. Defaults to the template lifecycle preview port, then `80`. |
| `domain` | string | No | Custom domain to attach. |
| `custom_domain` | string | No | Alias for `domain`, used by frontend clients. |

### Response  -  `201 Created`
```json
{
  "deployment_id": "dep_01j9xr2t4fk8me3n5q",
  "url": "https://my-app-a1b2c3.acme.miosa.app",
  "state": "running"
}
```

Managed deployment URLs are tenant-scoped: `https://{deployment-slug}.{tenant-slug}.miosa.app`. MIOSA persists the sandbox runtime target on the deployment and reconciles running routes, so a temporary proxy restart or admin API outage can be repaired from the database.

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 400 | `MISSING_PARAM` | `name` was omitted. |
| 409 | `SANDBOX_NOT_RUNNING` | Sandbox is not in `running` state. |
| 409 | `SANDBOX_RUNTIME_UNAVAILABLE` | Sandbox is marked running but has no VM IP yet. |
| 422 | `INVALID_PORT` | Port is outside `1` through `65535`. |
| 422 | `VALIDATION_ERROR` | Deployment record validation failed. |
```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_01j9xr2t4fk8me3n5q/deploy \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"my-app","port":8000}'
```

# Projects API

URL: https://miosa.ai/docs/api-reference/projects
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/projects
Source: src/routes/docs/api-reference/projects/+page.md
Description: API reference for creating and managing projects inside MIOSA workspaces.

A **Project** is the app, website, lead magnet, document, workflow, or customer build inside a workspace. Projects own sandboxes, computers, deployments, databases, storage buckets, volumes, functions, jobs, auth configuration, integrations, and custom domains.

Base path: `/api/v1/projects`

If a resource create call includes `project_slug`, `project_name`, or `external_project_id`, MIOSA resolves or creates the project before creating the resource. You can also create projects explicitly with this API.

## Endpoints

| Method | Path | Description |
|---|---|---|
| `GET` | `/projects` | List projects for the organization |
| `POST` | `/projects` | Create a project inside a workspace |
| `GET` | `/projects/{id}` | Get one project |
| `PATCH` | `/projects/{id}` | Update a project |
| `GET` | `/workspaces/{id}/projects` | List projects in one workspace |

---

## List Projects

**`GET /api/v1/projects`**

### Query Parameters

| Parameter | Type | Description |
|---|---|---|

Returns one project if it belongs to the authenticated organization.

```bash
curl https://api.miosa.ai/api/v1/projects/{id} \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Update a Project

**`PATCH /api/v1/projects/{id}`**

### Request Body

| Field | Type | Description |
|---|---|---|
| `name` | string | New display name |
| `slug` | string | New URL-safe slug, unique inside the workspace |

  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "Summer Lead Magnet"}'
```

---

## Use Projects on Resource Create

Most create endpoints accept the same ownership fields:

```json
{
  "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
  "project_id": "660e8400-e29b-41d4-a716-446655440001",
  "external_workspace_id": "acct_123",
  "external_project_id": "project_789"
}
```

You can use slugs instead of UUIDs:

```json
{
  "workspace_slug": "acme-corp",
  "workspace_name": "Acme Corp",
  "project_slug": "lead-magnet",
  "project_name": "Lead Magnet"
}
```

This applies to sandboxes, computers, deployments, databases, storage buckets, volumes, edge functions, cron jobs, project auth, and integrations. Derived records inherit ownership automatically.

---

## Domains

Projects do not own a preview domain. Preview domains are an organization
setting, and per-deployment custom domains are attached to the deployment:

- [Custom Domains API](/docs/api-reference/custom-domains/) - the organization preview domain and deployment/computer custom domains.

# Quotas API

URL: https://miosa.ai/docs/api-reference/quotas
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/quotas
Source: src/routes/docs/api-reference/quotas/+page.md
Description: Set per-end-user resource limits for white-label multi-tenant deployments.

Quotas let you cap how many sandboxes an individual end-user of your product can create and run. They are keyed by `external_user_id`  -  the same opaque identifier you pass when creating sandboxes on behalf of your users.

Base path: `/api/v1/quotas/external/{external_user_id}`

Quotas are enforced at sandbox creation time. Setting a quota does not affect sandboxes already running. Deleting a quota removes all limits for that user.

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/quotas/external/{external_user_id}` | Get quota and current usage |
| `PUT` | `/api/v1/quotas/external/{external_user_id}` | Create or update a quota |
| `DELETE` | `/api/v1/quotas/external/{external_user_id}` | Remove quota (unlimited) |

---

## Get Quota

**`GET /api/v1/quotas/external/{external_user_id}`**

Returns the configured limits and live usage counters for the user.

### Auth

```
Authorization: Bearer msk_...
```

### Response  -  `200 OK`

```json
{
  "data": {
    "external_user_id": "user_42",
    "limits": {
      "max_sandboxes": 10,
      "max_concurrent": 3,
      "max_storage_gb": 50,
      "max_credit_cents": 5000
    },
    "usage": {
      "total_sandboxes": 4,
      "concurrent": 1
    }
  }
}
```

| Field | Type | Description |
|-------|------|-------------|
| `limits.max_sandboxes` | integer\|null | Lifetime sandbox creation limit |
| `limits.max_concurrent` | integer\|null | Max sandboxes running simultaneously |
| `limits.max_storage_gb` | integer\|null | Total attached storage cap in GiB |
| `limits.max_credit_cents` | integer\|null | Spend cap in cents (platform credits) |
| `usage.total_sandboxes` | integer | Total sandboxes created by this user |
| `usage.concurrent` | integer | Currently running sandboxes |

A `null` limit means no cap is applied for that dimension.

---

## Set Quota

**`PUT /api/v1/quotas/external/{external_user_id}`**

Creates or replaces the quota. All limit fields are optional  -  omit a field to leave it uncapped.

### Request Body

```json
{
  "max_sandboxes": 10,
  "max_concurrent": 3,
  "max_storage_gb": 50,
  "max_credit_cents": 5000
}
```

### Response  -  `200 OK`

Same shape as GET response.

---

## Delete Quota

**`DELETE /api/v1/quotas/external/{external_user_id}`**

Removes all limits for the user. Future sandbox creation is governed only by your tenant plan.

### Response  -  `204 No Content`

---

## Errors

| Status | Code | Cause |
|--------|------|-------|
| 404 | `not_found` | No quota exists for this `external_user_id` (GET/DELETE) |
| 422 | validation errors | A limit value is non-integer or negative |

---

## Examples

```bash
# Set
curl -X PUT https://api.miosa.ai/api/v1/quotas/external/user_42 \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{"max_sandboxes": 10, "max_concurrent": 3}'

# Get
curl https://api.miosa.ai/api/v1/quotas/external/user_42 \
  -H "Authorization: Bearer msk_u_..."

# Remove
curl -X DELETE https://api.miosa.ai/api/v1/quotas/external/user_42 \
  -H "Authorization: Bearer msk_u_..."
```

```python

client = miosa.Miosa()

# Set quota when user signs up
client.quotas.set("user_42", max_sandboxes=10, max_concurrent=3)

# Check quota + usage
quota = client.quotas.get("user_42")
print(quota.usage.concurrent)

# Remove limits
client.quotas.delete("user_42")
```

```typescript

const client = new Miosa();

// Set
await client.quotas.set('user_42', {
  maxSandboxes: 10,
  maxConcurrent: 3,
  maxStorageGb: 50,
});

// Get
const quota = await client.quotas.get('user_42');
console.log(quota.usage.concurrent);

// Remove
await client.quotas.delete('user_42');
```

# Regions API

URL: https://miosa.ai/docs/api-reference/regions
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/regions
Source: src/routes/docs/api-reference/regions/+page.md
Description: List available regions and pin Computers and Sandboxes to a specific region.

MIOSA Computers and Sandboxes run in geographic regions. Every Computer (and every Sandbox, since a Sandbox is a lightweight Computer flavor) is created in exactly one region and stays there for its lifetime.

Base path: `/api/v1/regions`

---

## Overview

- **3 regions are live today.** All have equal status  -  none are preview, none are restricted.
- **Default region** when you don't specify one: `us-west`.
- **All VM sizes** (XS, S, M, L, XL) are available in every region for both Computers and Sandboxes.
- **Latency** is roughly equidistant for US users  -  pick by data residency or proximity preference rather than performance.
- **No multi-region resources.** A Computer lives in exactly one region. To run workloads in multiple regions, create multiple Computers.

---

## Available Regions

| Slug             | Location          | City             | Status |
|------------------|-------------------|------------------|--------|
| `us-west`     | US West           | Los Angeles, CA  | Live   |
| `us-east`     | US East           | New York, NY     | Live   |
| `us-mia`  | US East 2        | Miami         | Live   |

The region slug is what you pass on create and what comes back on read  -  every Computer and Sandbox response includes a `region` field, e.g. `"region": "us-west"`.

---

## Specify a region on create

Pass `region` in the request body when creating a Computer or Sandbox. If omitted, the default (`us-west`) is used.

```python
  computer = client.computers.create(
      name="ny-build-box",
      size="M",
      region="us-east",
  )
  print(computer.region)  # "us-east"
```

```typescript
  const computer = await client.computers.create({
    name: 'ny-build-box',
    size: 'M',
    region: 'us-east',
  });
  console.log(computer.region); // "us-east"
```

```bash
  curl -X POST https://api.miosa.ai/api/v1/computers \
    -H "Authorization: Bearer $MIOSA_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
      "name": "ny-build-box",
      "size": "M",
      "region": "us-east"
    }'
```

The same `region` field works on `POST /api/v1/sandboxes`.

### Errors

| Status | Error                | Cause                                          |
|--------|----------------------|------------------------------------------------|
| 400    | `invalid_region`     | Slug not in the list above                     |
| 409    | `region_unavailable` | Transient capacity issue  -  retry or pick another |

---

## Default region behavior

If `region` is omitted from the create request:

- The resource resolves to your tenant's default region (`us-west` by default; change it in dashboard settings  -  that override applies to API calls that omit `region`).
- The response still includes the resolved `region` so you always know where the resource lives.

---

## List regions

**`GET /api/v1/regions`**

Returns the regions available to your tenant. Useful for region pickers in UIs.

### Response  -  `200 OK`
```json
{
  "regions": [
    {
      "id": "us-west",
      "label": "US-West (Los Angeles)",

```bash
curl https://api.miosa.ai/api/v1/regions \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

The list endpoint is unauthenticated-friendly  -  you can use a short-lived ticket or a public token to populate region pickers without exposing your `msk_*` key.

## FAQ

### Why these 3 regions?

We picked Los Angeles, New York, and Miami to cover the US west coast, east coast, and central corridor. The three sites are roughly equidistant for the median US user, and they each sit on independent network and power footprints  -  so a regional outage at one doesn't take the others down.

### How do I pick a region?

Pick by **data residency** first. If you have a customer or compliance requirement that pins data to a coast, that decides for you.

If you have no residency requirement, pick by **proximity to your users or your CI runners**  -  shorter physical distance means lower RTT for VNC streaming and PTY round-trips. Compute performance itself is identical across regions.

### Can a Computer span multiple regions?

No. A Computer (or Sandbox) lives in exactly one region for its lifetime. To run workloads in multiple regions:

- Create one Computer per region.
- Use OpenComputers federation if you want a single logical workspace across them (see [OpenComputers](/docs/api-reference/open-computers/)).

There's no live migration between regions today.

### Will more regions ship?

Yes  -  EU and APAC regions are on the roadmap. When they ship they'll appear in `GET /api/v1/regions` alongside the current three. Watch the [changelog](/docs/changelog/) for announcements.

# Releases API

URL: https://miosa.ai/docs/api-reference/releases
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/releases
Source: src/routes/docs/api-reference/releases/+page.md
Description: Inspect and activate exact immutable deployment artifacts.

A **Release** is the immutable artifact produced from a build or sandbox publish.
It records the artifact digest, runtime command, port, health check, source attribution, and readiness state used for an exact promotion.

Base path: `/api/v1/deployments/{deployment_id}/releases`

## Endpoints

| Method | Path | Purpose |
|---|---|---|
| `GET` | `/deployments/{deployment_id}/releases` | List releases for one deployment |
| `GET` | `/deployments/{deployment_id}/releases/{release_id}` | Inspect one exact release |
| `POST` | `/deployments/{deployment_id}/releases/{release_id}/promote` | Activate one exact release |

Publish creates the candidate release.
Promotion changes the active production artifact only after the requested release is ready and the configured runtime accepts it.

## List releases

```bash
curl https://api.miosa.ai/api/v1/deployments/$DEPLOYMENT_ID/releases \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

The response contains `data`, a compatibility `releases` array, and `total`.

```json
{

}
```

## Inspect one release

```bash
curl \
  https://api.miosa.ai/api/v1/deployments/$DEPLOYMENT_ID/releases/$RELEASE_ID \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Use this endpoint to confirm the exact artifact digest, runtime contract, source sandbox, build, and readiness state before promotion.

## Promote one exact release

Promotion is a mutation and requires an idempotency key.

```bash
curl -X POST \
  https://api.miosa.ai/api/v1/deployments/$DEPLOYMENT_ID/releases/$RELEASE_ID/promote \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY"
```

The response contains the deployment plus the durable operation record.
Repeating the same request with the same idempotency key returns the existing result instead of activating the release twice.

Promotion uses the deployment's configured runtime product.
For Docker Host, the release is activated through the workspace Docker Host host.
For standard MIOSA Deploy, it is activated through the standard dynamic or static runtime.

## CLI

```bash
miosa deploy releases <deployment-id> --json
miosa deploy versions <deployment-id> --json
miosa deploy promote <deployment-id> <release-id> --json
miosa deploy rollback <deployment-id> --to <release-id> --yes --json
```

## Immutability

A release is content-addressed by `artifact_sha256`.
Changing application content creates a new release.
Promotion never mutates the bytes of an existing release.

Rollback selects a previously ready release and activates that exact artifact through the same runtime-aware path.

# Runtime Env

URL: https://miosa.ai/docs/api-reference/runtime-env
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/runtime-env
Source: src/routes/docs/api-reference/runtime-env/+page.md
Description: Store inherited runtime environment variables for sandboxes, computers, agents, and deployments.

# Runtime Env

Runtime Env stores inherited environment variables for tenant, workspace, and
project scopes. Values are encrypted at rest and are never returned in
plaintext. MIOSA materializes them into sandboxes, computers, agents, or
deployments according to the target you choose.

Base path: `/api/v1/runtime-env`

Runtime Env can hold provider keys such as Anthropic, OpenAI, Higgsfield,
Resend, Stripe, or customer API tokens. Scope them as narrowly as possible and
avoid putting tenant admin credentials into broad defaults.

## Endpoints

| Method | Path | Description |
|---|---|---|
| `GET` | `/api/v1/runtime-env` | List inherited env variables |
| `POST` | `/api/v1/runtime-env` | Create or update one variable |
| `GET` | `/api/v1/runtime-env/{id}` | Show one variable without plaintext |
| `DELETE` | `/api/v1/runtime-env/{id}` | Delete one variable |

List supports these filters:

| Query | Values |
|---|---|
| `scope` | `tenant`, `workspace`, `project` |
| `workspace_id` | Workspace id for workspace-scoped variables |
| `project_id` | Project id for project-scoped variables |
| `target` | `all`, `sandbox`, `computer`, `agent`, `deployment` |

## Create

```http
POST /api/v1/runtime-env
Authorization: Bearer msk_u_...
Content-Type: application/json
```

```json
{
  "scope": "workspace",
  "workspace_id": "ws_123",
  "target": "sandbox",
  "name": "ANTHROPIC_API_KEY",
  "value": "sk-ant-...",
  "metadata": {
    "provider": "anthropic",
    "owner": "lumen"
  }
}
```

Environment variable names must be uppercase shell-safe names matching
`/^[A-Z][A-Z0-9_]*$/`.

## Scope model

| Scope | Required id | Use it for |
|---|---|---|
| `tenant` | none | Organization-wide defaults. |
| `workspace` | `workspace_id` | A customer/workspace provider key or tool config. |
| `project` | `project_id` | A single app or deployment pipeline. |

| Target | Receives the variable |
|---|---|
| `all` | All supported runtime targets. |
| `sandbox` | Sandbox sessions and sandbox agent runs. |
| `computer` | Desktop computer sessions and computer agent runs. |
| `agent` | Agent runtime sessions. |
| `deployment` | Production deployment/runtime boot. |

Use narrower scopes for spend-capable keys. For example, set
`ANTHROPIC_API_KEY` at workspace scope for Lumen instead of tenant scope if
that key should only power Lumen sandboxes and computers.

## CLI

Runtime Env has no dedicated `miosa` subcommand; drive it with `miosa api`
against the `/runtime-env` endpoint.

```bash
miosa api POST /runtime-env -d '{
  "name": "ANTHROPIC_API_KEY",
  "value": "sk-ant-...",
  "scope": "workspace",
  "workspace_id": "ws_123",
  "target": "sandbox"
}'

miosa api POST /runtime-env -d '{
  "name": "HIGGSFIELD_API_KEY",
  "value": "hgf_...",
  "scope": "project",
  "project_id": "proj_123",
  "target": "agent"
}'

miosa api GET /runtime-env?scope=workspace&workspace_id=ws_123
miosa api GET /runtime-env/env_123
miosa api DELETE /runtime-env/env_123
```

## Relationship to profiles and connectors

Runtime Env, Agent Runtime Profiles, and managed connectors are separate:

| Primitive | Owns |
|---|---|
| Runtime Env | Inherited environment variables and encrypted provider keys. |
| Agent Runtime Profile | Runtime choice, tools, connectors, default env, and policy. |
| Managed connector | Brokered provider access and scoped token exchange. |

Use Runtime Env for direct provider environment variables. Use connectors when
MIOSA should broker provider access or restrict egress. Use profiles to attach
the right defaults to new sandboxes, computers, and agent runs.

## Next


    Standardize runtimes, tools, connectors, and policy for each workspace or project.


    Dispatch prompts with inherited env and runtime profile resolution.


    Put inherited env, profiles, groups, events, and artifacts together.

# Sandbox Env API

URL: https://miosa.ai/docs/api-reference/sandbox-env
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandbox-env
Source: src/routes/docs/api-reference/sandbox-env/+page.md
Description: CRUD for per-sandbox environment variables, encrypted at rest.

The sandbox env API manages a key-value store of environment variables attached to a sandbox. Variables are encrypted at rest and injected into the sandbox process environment on start. The API never returns plaintext values  -  only key names and metadata.

Base path: `/api/v1/sandboxes/{id}/env`

Variable names must match `[A-Z][A-Z0-9_]*`  -  uppercase letters, digits, and underscores, starting with a letter. This mirrors POSIX shell environment variable conventions.

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/sandboxes/{id}/env` | List all env vars (names only, no values) |
| `PUT` | `/api/v1/sandboxes/{id}/env` | Bulk set or update env vars |
| `DELETE` | `/api/v1/sandboxes/{id}/env/{key}` | Delete a single env var |

---

## List Env Vars

**`GET /api/v1/sandboxes/{id}/env`**

# Sandbox Files (Advanced) API

URL: https://miosa.ai/docs/api-reference/sandbox-files-advanced
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandbox-files-advanced
Source: src/routes/docs/api-reference/sandbox-files-advanced/+page.md
Description: Upload a file, write bytes as well as text, traverse the file tree, batch write, and watch file-change events in a sandbox.

These advanced file operations extend the core [Files API](/docs/api-reference/files) with IDE-oriented capabilities: recursive tree listing, atomic batch writes, and a live file-change event stream.

Base path: `/api/v1/sandboxes/{id}/files`, and `/api/v1/sandboxes/{id}/fs` for the upload route.

These routes use `:sandbox_id` as the path parameter internally but are accessed as `/sandboxes/{id}/files/...`  -  the `{id}` segment is the sandbox UUID.

File read, write, list, mkdir, and remove work on a SOMA sandbox through these routes.
They no longer answer `501 FILES_UNSUPPORTED_ON_RUNTIME`.
Files on SOMA are kept only while the sandbox runs, because SOMA does not persist state across a stop yet.
See [Choosing a runtime](/docs/soma/choosing-a-runtime/).

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/sandboxes/{id}/files/tree` | Recursive file tree |
| `POST` | `/api/v1/sandboxes/{id}/files/write-many` | Batch write multiple files |
| `GET` | `/api/v1/sandboxes/{id}/files/watch` | SSE stream of file-change events |
| `POST` | `/api/v1/sandboxes/{id}/fs/upload` | Upload a file (multipart) |

---

## Upload a file

**`POST /api/v1/sandboxes/{id}/fs/upload`**

Send the bytes as multipart form data.
This is the route the SDKs use, and the only upload route today.

| Field | Type | Required | Description |
|---|---|---|---|
| `file` | file | Yes | The bytes to write. A missing part answers `400 MISSING_FILE`. |
| `path` | string | No | Destination. Defaults to `/home/user/`. A trailing slash appends the uploaded filename; without one, `path` is the exact destination. |

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/fs/upload \
  -H "Authorization: Bearer msk_u_..." \
  -F "path=/workspace/assets/" \
  -F "file=@./logo.png"
```

### Errors

| Status | Code | Cause |
|---|---|---|
| 400 | `MISSING_FILE` | No `file` part. |
| 400 | `INVALID_PATH` | `path` contains a null byte. |
| 413 | `FILE_TOO_LARGE` | The upload exceeds the size limit. |

`/api/v1/sandboxes/{id}/files/upload` is an alias of this route.

---

## Write bytes, not text

`/files/write` stores `content` verbatim, so it is for text.
For anything binary, send `content_base64` instead; `/files/write-many` takes it per file.

```bash
# macOS uses `base64 -i`, GNU coreutils uses `base64 -w0`
B64=$(base64 -i ./logo.png | tr -d '\n')
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/files/write \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  --data "$(jq -n --arg p /workspace/logo.png --arg b "$B64" '{path: $p, content_base64: $b}')"
```

---

## File Tree

**`GET /api/v1/sandboxes/{id}/files/tree`**

Returns a recursive directory listing up to a configurable depth. Useful for populating an IDE file-explorer panel.

### Auth

```
Authorization: Bearer msk_...
```

### Query Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `path` | string | `/workspace` | Root directory to list |

            "modified_at": "2026-05-26T09:12:01Z"
          }
        ]
      },
      {
        "name": "package.json",
        "path": "/workspace/package.json",
        "type": "file",
        "size": 512,
        "modified_at": "2026-05-25T18:00:00Z"
      }
    ]
  }
}
```

---

## Batch Write

**`POST /api/v1/sandboxes/{id}/files/write-many`**

Writes multiple files in a single request. All writes are applied atomically from the guest's perspective  -  either all succeed or an error is returned for the failing file.

Maximum 50 files per request. Files larger than 90 KB should be uploaded individually via `POST /files/write`.

### Request Body

```json
{
  "files": [
    {
      "path": "/workspace/src/index.ts",
      "content": "export const hello = () => 'world';\n",
      "encoding": "utf8"
    },
    {
      "path": "/workspace/src/utils.ts",
      "content": "ZXhwb3J0IGZ1bmN0aW9uIG5vb3AoKSB7fQo=",
      "encoding": "base64"
    }
  ]
}
```

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `files[].path` | string | Yes | Absolute path inside the sandbox |
| `files[].content` | string | Yes | File content (UTF-8 text or base64-encoded binary) |

  "data": {
    "written": 2,
    "paths": [
      "/workspace/src/index.ts",
      "/workspace/src/utils.ts"
    ]
  }
}
```

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 400 | `INVALID_BODY` | `files` is missing or not an array |
| 400 | `TOO_MANY_FILES` | More than 50 files in one request |
| 400 | `INVALID_PATH` | A path contains a null byte or traverses outside the sandbox |

---

## File Watch (SSE)

**`GET /api/v1/sandboxes/{id}/files/watch`**

Streams file-system change events as SSE. Useful for syncing editor state in real time.

### Auth

```
Authorization: Bearer msk_...
```

(Browser `EventSource` cannot set this header  -  use a server-side client or a scoped session token.)

### Query Parameters

| Parameter | Type | Default | Description |
|-----------|------|---------|-------------|
| `path` | string | `/workspace` | Directory to watch |

### Response  -  `200 OK` (`text/event-stream`)

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandbox-processes
Source: src/routes/docs/api-reference/sandbox-processes/+page.md
Description: Start, monitor, and stream logs for long-running background processes inside sandboxes.

The processes API lets you launch long-running background commands inside a sandbox and inspect their output  -  useful for starting dev servers, watchers, or any process that runs beyond a single exec call.

Base path: `/api/v1/sandboxes/{id}/processes`

Processes are managed by the sandbox runtime and survive for the lifetime of the sandbox. They are not preserved across snapshots or forks.

# Sandbox Shares API

URL: https://miosa.ai/docs/api-reference/sandbox-shares
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandbox-shares
Source: src/routes/docs/api-reference/sandbox-shares/+page.md
Description: Create and manage public share URLs for sandboxes.

Sandbox shares are publicly accessible URLs that give read-only access to a running sandbox. Unlike preview tokens, share URLs are not scoped to an iframe and do not require the recipient to hold any credentials.

Share tokens use the prefix `ms_` followed by a base64url-encoded payload. The public URL pattern is:

```
https://{sandbox-id}.sandboxes.miosa.ai?ms=ms_<token>
```

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `POST` | `/api/v1/sandboxes/{id}/shares` | Create a share URL |
| `GET` | `/api/v1/sandboxes/{id}/shares` | List active shares |
| `DELETE` | `/api/v1/sandboxes/{id}/shares/{share_id}` | Revoke a share |

---

## Create a Share

**`POST /api/v1/sandboxes/{id}/shares`**

Creates a public share link. The `share_url` field is safe to distribute  -  it contains the token as a query parameter.

### Auth

```
Authorization: Bearer msk_...
```

### Request Body

| Field | Type | Required | Default | Description |
|-------|------|----------|---------|-------------|
| `expires_in` | integer | No | `3600` | TTL in seconds |
| `scope` | string | No | `"read"` | Must be `"read"` (only supported value) |

```json
{
  "expires_in": 86400
}
```

### Response  -  `201 Created`

```json
{
  "share_id": "shr_01hx9m7n3k...",
  "share_url": "https://sbx-abc123.sandboxes.miosa.ai?ms=ms_eyJ...",
  "expires_at": "2026-05-27T12:00:00Z",
  "scope": "read"
}
```

| Field | Type | Description |
|-------|------|-------------|
| `share_id` | string | Opaque share identifier used to revoke |
| `share_url` | string | Publicly accessible URL with token embedded |
| `expires_at` | string | ISO 8601 expiry, or `null` for no expiry |
| `scope` | string | Always `"read"` |

---

## List Shares

**`GET /api/v1/sandboxes/{id}/shares`**

Returns all active (non-revoked, non-expired) shares for the sandbox.

### Response  -  `200 OK`

```json
{
  "data": [
    {
      "share_id": "shr_01hx9m7n3k...",
      "share_url": "https://sbx-abc123.sandboxes.miosa.ai?ms=ms_eyJ...",
      "expires_at": "2026-05-27T12:00:00Z",
      "scope": "read"
    }
  ]
}
```

---

## Revoke a Share

**`DELETE /api/v1/sandboxes/{id}/shares/{share_id}`**

Immediately invalidates the share. Any visitor using the share URL will receive a 403 after revocation.

### Response  -  `204 No Content`

No response body.

---

## Errors

| Status | Code | Cause |
|--------|------|-------|
| 404 | `sandbox_not_found` | Sandbox does not exist or wrong tenant |
| 403 | `forbidden` | Tenant mismatch |
| 404 | `not_found` | Share ID does not exist (on DELETE) |
| 422 | `invalid_scope` | `scope` value is not `"read"` |

---

## Examples

```bash
# Create
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/shares \

# Sandbox Templates API

URL: https://miosa.ai/docs/api-reference/sandbox-templates
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandbox-templates
Source: src/routes/docs/api-reference/sandbox-templates/+page.md
Description: The templates that stage content inside the one sandbox image, the legacy image ids that are aliases, and how to create a sandbox from a template.

Sandbox templates are pre-built images with toolchains, dependencies, and configuration baked in. Launching from a template is faster than installing packages at runtime and ensures reproducible environments.

Every sandbox boots the same main image. A template is content staged inside that image at create time, never a separate image. See the [Templates guide](/docs/develop/templates/).

Templates are read-only marketplace items managed by MIOSA. To build your own custom templates, see the [Templates guide](/docs/develop/templates).

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/sandbox-templates` | List the templates available to you |
| `GET` | `/api/v1/sandbox-templates/{id}` | Get a specific template |
| `POST` | `/api/v1/sandboxes` | Create a sandbox from a template (via `template_id`) |

---

## List templates

**`GET /api/v1/sandbox-templates`**

Returns the built-in catalog plus any custom templates your workspace has built, as a JSON array.
Each row carries the template `slug`, its `source` (`builtin` or `workspace`), and the registry `status`.

Alias ids are left out by default. Pass `include_aliases=true` to include them; each alias is nested on the row it resolves to, under `aliases`.

```bash
curl "https://api.miosa.ai/api/v1/sandbox-templates?include_aliases=true" \
  -H "Authorization: Bearer msk_u_..."
```

---

## Listed templates

Five templates are listed, and all five run the one image:

| `template_id` | Kind | What it is |
|---|---|---|
| `miosa-sandbox` | `image` | The default sandbox. Everything inside, and what you get when you omit `template_id`. |
| `nextjs` | `starter` | Stages a Next.js app in the sandbox and starts it on port 3000. |
| `nextjs-postgres` | `starter` | A Next.js app with Postgres client tooling on port 3000; bind `DATABASE_URL`. |
| `static-html` | `starter` | Static HTML, CSS, and JavaScript served from `/workspace` on port 8000. |
| `fastapi-auth` | `starter` | A FastAPI starter with signup, login, me, and dashboard routes, on port 8000. Its health check does not work yet. |

The four starter templates add only content inside the image: the scaffold, the install command, and the start command.
Templates your workspace builds are returned with kind `custom`.
`miosa-desktop` is a separate Computer product, not a sandbox template; see [Computers](/docs/computers/overview/).

---

## Aliases

Alias ids are never listed, and still work as `template_id`.

These resolve to `miosa-sandbox`, the plain image:

`miosa-sandbox-prod-1`, `miosa-sandbox-docker`, `agent-browser`, `instant-code`, `bookworm`, `debian-12`, `docker`, `sandbox-docker`, `browser-agent`, `code`, `instant`, `instant-node`, `node-20`, `postgres-15`, `postgres-16`, `ubuntu-22.04`, `ubuntu-24.04`.

These resolve to a starter, which stays listed:

`static` to `static-html`; `next-postgres` and `fullstack-next-postgres` to `nextjs-postgres`; `python-auth` and `fastapi-auth-starter` to `fastapi-auth`.

---

## Create a sandbox from a template

**`POST /api/v1/sandboxes`**

```json
{
  "template_id": "nextjs",
  "size": "small"
}
```

Omit `template_id` for a sandbox with nothing staged, or pass a content template to stage a scaffold inside the same image.
For a desktop, create a Computer with `template_type: "miosa-desktop"`; see [Computers](/docs/computers/overview/).

See the [Sandboxes API](/docs/api-reference/sandboxes) for the full creation reference.

---

## Errors

| Status | Code | Cause |
|--------|------|-------|
| 404 | `not_found` | Template ID does not exist |

---

## Examples

```bash
# List templates, including the legacy alias ids
curl "https://api.miosa.ai/api/v1/sandbox-templates?include_aliases=true" \
  -H "Authorization: Bearer msk_u_..."

# Get one template
curl https://api.miosa.ai/api/v1/sandbox-templates/nextjs \
  -H "Authorization: Bearer msk_u_..."

# Create a sandbox with the Next.js template staged
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{"template_id": "nextjs", "size": "small"}'
```

```python

client = miosa.Miosa()

# Browse templates

for t in templates:
    print(t.slug, "-", t.description)

# Create the default sandbox
sandbox = client.sandboxes.create(template_id="nextjs", size="small")
```

```typescript

const client = new Miosa();

// Browse
const templates = await client.sandboxTemplates.list();
for (const t of templates) {
  console.log(t.slug, '-', t.description);
}

// Create a sandbox with the Next.js template staged
const sandbox = await client.sandboxes.create({
  templateId: 'nextjs',
  size: 'small',
});
```

# Sandboxes API

URL: https://miosa.ai/docs/api-reference/sandboxes
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandboxes
Source: src/routes/docs/api-reference/sandboxes/+page.md
Description: API reference for creating, managing, and executing code in MIOSA sandboxes - persistent-by-default isolated microVM workspaces.

Sandboxes are persistent-by-default isolated microVM workspaces that restore from pre-seeded snapshots, accept exec and file operations, expose previews, and are billed by compute/runtime usage. They are designed for AI-agent code execution workloads, artifact generation, and app previews.

Base path: `/api/v1/sandboxes`

All endpoints require `Authorization: Bearer &lt;api_key&gt;`. Get a key from the [MIOSA dashboard](https://miosa.ai/settings/api-keys).

For higher-level access, use the official SDKs: [Python](/docs/sdks/python/), [TypeScript](/docs/sdks/typescript/), [Go](/docs/sdks/go/), [Java](/docs/sdks/java/), [Elixir](/docs/sdks/elixir/).


    Create a sandbox, the fused run endpoint, template apps, artifacts, and custom templates.


    List, get, destroy, pause, resume, fork, extend the timeout, and read usage.


---

## List sandbox templates and sizes

**`GET /api/v1/templates`**

This is the canonical catalog for sandbox template IDs, template defaults, per-template size support, readiness, and exact versioned resource contracts.
Clients need no secondary catalog endpoint to discover or admit a sandbox configuration.
```bash
curl https://api.miosa.ai/api/v1/templates
```

### Response  -  `200 OK`
```json
{
  "data": [
    {
      "id": "miosa-sandbox",
      "name": "MIOSA Sandbox",
      "product": "sandbox",
      "default_size": "small",
      "primitive": "sandbox",
      "sdk_name": "miosa-sandbox",
      "cli_name": "miosa-sandbox",
      "readiness": "fast_ready",
      "sizes": [
        {
          "size": "small",
          "state": "fast_ready",
          "resource_contract": {
            "contract_id": "sandbox/small@v1",
            "contract_version": "v1",
            "product": "sandbox",
            "size": "small",
            "vcpus": 2,
            "memory_mb": 4096,
            "disk_size_mb": 10240
          }
        }
      ]
    }
  ],
  "templates": [
    {
      "id": "miosa-sandbox",
      "name": "MIOSA Sandbox",
      "product": "sandbox",
      "default_size": "small",
      "primitive": "sandbox",
      "sdk_name": "miosa-sandbox",
      "cli_name": "miosa-sandbox",
      "readiness": "fast_ready",
      "sizes": [
        {
          "size": "small",
          "state": "fast_ready"
        }
      ]
    }
  ],
  "shape_contracts": {
    "sandbox": [],
    "computer": []
  },
  "readiness_states": ["fast_ready", "cold_boot_only", "missing"]
}
```

`fast_ready` sizes are creatable through the fast start path.
`cold_boot_only` sizes are also creatable but start more slowly.
`missing` means unavailable and must not be submitted.
Use that template's `default_size` when the caller does not have a stronger requirement.
Do not combine a size advertised by one template with another template.

---

## Configuration and request parameters

`GET /api/v1/templates` returns platform configuration: available templates, the default size, readiness, and versioned resource contracts.
Applications select that configuration with sandbox parameters; they do not send internal host, provider, network, or placement fields.

Prefer `size` for create requests.
The default `small` contract is 2 vCPU, 4096 MiB RAM, and 10240 MiB disk.
`xs` is selectable when the catalog reports it as available.
Compatibility resource fields must include `cpu_count`, `memory_mb`, and `disk_size_mb` together and exactly match one published contract.

Responses include the resolved contract under `resource_contract`.
Contract IDs are versioned, for example `sandbox/small@v1`; persist that identity when usage or audit records must remain reproducible.

---

## Sandbox Object

The full sandbox object returned by create, get, and list endpoints:

| Field | Type | Description |
|-------|------|-------------|
| `id` | string | Unique sandbox identifier. |
| `tenant_id` | string | Owning tenant ID. |
| `owner_id` | string | Creating user ID. |
| `template_id` | string | Boot template name. |
| `state` | string | Current lifecycle state. |
| `size` | string | Canonical named size: `xs`, `small`, `medium`, `large`, or `xl`. |

| `cpu_count` | integer | Allocated vCPUs. |
| `memory_mb` | integer | Allocated RAM in MB. |
| `disk_size_mb` | integer | Allocated root disk in MB. |
| `ready` | boolean | Whether command and readiness checks are accepting work. |
| `ready_at` | string/null | ISO timestamp when `ready` became true. |
| `preview_url` | string/null | Tenant-aware base preview URL for the sandbox slug. Use `/expose` for a specific port. |
| `timeout_sec` | integer | Max seconds for the active session. Persistent timeout pauses; non-persistent timeout destroys. |
| `timeout_remaining_ms` | integer \| null | Remaining active-session time; null before start or when timeout enforcement is disabled. |
| `always_on` | boolean | Whether timeout and idle-timeout enforcement are disabled. |
| `persistent` | boolean | Whether the sandbox preserves filesystem state across stop/timeout. |
| `idle_timeout_sec` | integer | Seconds without activity before the sandbox pauses. `0` disables it; accounts created on or after October 11, 2026 default to `1800` (30 minutes) when unset. |
| `total_runtime_sec` | integer \| null | Billed seconds. Set only after destruction. |
| `metadata` | object | Caller-supplied metadata. |
| `created_at` | string | ISO-8601 creation timestamp. |
| `started_at` | string \| null | ISO-8601 timestamp when VM entered `running`. |
| `destroyed_at` | string \| null | ISO-8601 timestamp when VM was destroyed. |

---

## Lifecycle States

| State | Description |
|-------|-------------|
| `provisioning` | VM is booting. Exec and file operations are not yet available. |
| `running` | VM is reachable. All operations allowed. |
| `paused` | Compute is stopped and filesystem state is preserved. Can be resumed. |
| `destroyed` | Terminal. VM is gone, billing is settled. |
| `error` | Terminal failure. Destroy and create a new sandbox. |

---

## Error Response Format

All error responses use this shape:
```json
{
  "error": {
    "code": "NOT_FOUND",
    "message": "sandbox not found",
    "details": null
  }
}
```

The `x-request-id` response header is set on every request. Include it in support requests.

---

## Code interpreter

**`POST /api/v1/sandboxes/{id}/code/run`** (alias: `POST /api/v1/sandboxes/{id}/code`)

Runs one cell in a persistent interpreter and returns its output.
The kernel starts lazily on first use, and variables, imports and definitions persist across calls in the same context.
`language` is `python` (the default) or `javascript`; an unsupported value returns `400 UNKNOWN_LANGUAGE`.
`context` names an independent namespace, `default` unless you pass one; `timeout` is capped at 300 seconds.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/code/run \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "code": "total = sum(range(10))\ntotal", "language": "python" }'
```

```json
{
  "data": {
    "ok": true,
    "stdout": "",
    "stderr": "",
    "result": "45",
    "language": "python"
  }
}
```

| Endpoint | What it does |
|---|---|
| `GET /api/v1/sandboxes/{id}/code` | Report interpreter state. Never starts a kernel. Returns `sandbox_not_running` when the sandbox is not running. |
| `GET /api/v1/sandboxes/{id}/code/contexts?language=` | List the contexts that exist for a language. |
| `POST /api/v1/sandboxes/{id}/code/contexts` | Create or reuse a context. |
| `DELETE /api/v1/sandboxes/{id}/code/contexts/{context}` | Reset one context. |
| `DELETE /api/v1/sandboxes/{id}/code?language=` | Reset every context for a language. |

Reading (`GET`) needs `sandboxes:read`; running and resetting need `sandboxes:exec`.
The sandbox must be running: the interpreter does not wake a paused sandbox.

---

## Rate Limits

| Limit | Value |
|-------|-------|
| Request rate | Enforced per workspace and per endpoint group; an over-limit response carries `Retry-After` |
| Concurrent sandboxes per tenant | Plan cap: 10 (Developer), 250 (Business), 500 (Enterprise) |
| `timeout_sec` | 1-86400 seconds; default 3600 |
| Default resource shape | `small`: 2 vCPU, 4 GiB RAM, 10 GiB disk |
| Named resource schema | `xs` through `xl`; actual availability comes from `GET /templates` and tenant policy |
| Max exec timeout | 1-86400 seconds; default 3600 |
| Max file upload size | 500 MB |

Rate-limited responses return HTTP `429` with a `Retry-After` header indicating seconds to wait.

# Sandboxes API - create and run

URL: https://miosa.ai/docs/api-reference/sandboxes/create
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/sandboxes/create
Source: src/routes/docs/api-reference/sandboxes/create/+page.md
Description: Create a MIOSA sandbox, use the fused run endpoint, start a template app, get artifacts, and the custom-template boundary.

# Create and run

Base path: `/api/v1/sandboxes`

All endpoints require `Authorization: Bearer &lt;api_key&gt;`.

## Create a Sandbox

**`POST /api/v1/sandboxes`**

Spawns a new sandbox VM. The API returns the sandbox record immediately after the create request is accepted; poll `GET /api/v1/sandboxes/{id}` or subscribe to events until `state` is `running` and `ready` is `true`.

The production alias `miosa-sandbox` resolves to a certified immutable artifact generation.

### Auth

Bearer token required.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `template_id` | string | No | Template to stage inside the sandbox image at create. Omit it for a sandbox with nothing staged. See templates below. |
| `size` | string | No | Canonical resource configuration. Defaults to `small` (`2 vCPU`, `4096 MiB`, `10240 MiB` disk). |
| `cpu_count` | integer | No | Exact vCPU compatibility input. Supply the full matching resource triple. |
| `memory_mb` | integer | No | Exact RAM override. It must match the selected canonical size. |
| `disk_size_mb` | integer | No | Exact disk override. It must match the selected canonical size. `disk_mb` is deprecated. |
| `timeout_sec` | integer | No | Active-session timeout. Defaults to `3600`; minimum `1`, maximum `86400`. |
| `always_on` | boolean | No | Disable timeout and idle-timeout enforcement until an explicit lifecycle action. Defaults to `false` and remains subject to policy. |
| `persistent` | boolean | No | Defaults to `true`. Preserve filesystem state across stop/timeout and allow resume. Set `false` only for disposable one-off jobs. |
| `idle_timeout_sec` | integer | No | Seconds without activity before the sandbox pauses. Left unset, it defaults to `0` (disabled), or `1800` (30 minutes) for accounts created on or after October 11, 2026; set `0` to disable. |
| `env` | object | No | Key-value env vars injected at boot. |
| `metadata` | object | No | Arbitrary caller-supplied metadata stored on the record. |
| `agent_runtime_profile_id` | UUID/string | No | Force a specific agent runtime profile for this sandbox. Alias: `agent_profile_id`. |
| `skip_agent_runtime_profile` | boolean | No | If `true`, do not apply the tenant/workspace default runtime profile. |
| `auto_start` | boolean | No | If `true`, MIOSA starts the selected template after the sandbox reaches `running`. Generated-app platforms usually keep this false, write files first, then call `/template/start`. |
| `workspace_id` | UUID | No | Existing MIOSA workspace that owns the sandbox. Defaults to the organization default workspace. |
| `workspace_slug` | string | No | Existing or auto-created workspace slug. |
| `workspace_name` | string | No | Workspace display name if auto-created. |
| `project_id` | UUID | No | Existing MIOSA project that owns the sandbox. Defaults to the workspace default project. |
| `project_slug` | string | No | Existing or auto-created project slug inside the workspace. |
| `project_name` | string | No | Project display name if auto-created. |
| `external_workspace_id` | string | No | Your customer/account/workspace ID. |
| `external_user_id` | string | No | Your end-user ID. |
| `external_project_id` | string | No | Your project/app/document ID. |

If a default agent runtime profile exists for the workspace or tenant, MIOSA
applies it automatically during create. Profile env vars are merged with request
env vars, request env wins on conflict, profile metadata is recorded under
`metadata.agent_runtime_profile`, and profile connectors are attached through
egress placeholder tokens rather than copied as plaintext secrets.

**Available templates:**

| `template_id` | Description |
|---------------|-------------|
| `miosa-sandbox` | The default sandbox, and the default when you omit `template_id`. Everything inside: Docker Engine 29.9 with `docker compose` and `docker buildx`, a live browser with CDP on a virtual display, the persistent code interpreter, Node, and Python. |

Every other built-in id is an alias of `miosa-sandbox`, kept so existing code keeps working; the [Sandbox Templates API](/docs/api-reference/sandbox-templates/) lists them.
For a desktop, create a Computer with `template_type: "miosa-desktop"`; see [Computers](/docs/computers/overview/).

### Request Headers

| Header | Description |
|--------|-------------|
| `Idempotency-Key` | Client-generated key (UUID recommended). Same key within 24 h returns the existing sandbox instead of creating a new one. |

## Create and Run

**`POST /api/v1/sandboxes/run`**

Creates a sandbox, waits for it to become `running`, executes the first command, and returns the sandbox record plus the command result in one request. Use this for agent loops where the first useful action is "create a sandbox and run code now."

This is the production fast path for agents that need a sandbox and an immediate first command.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/run \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: run-2026-06-09-001" \
  -d '{
    "template_id": "miosa-sandbox",
    "command": "python3 -c \"print(1+1)\"",
    "size": "small",
    "timeout_sec": 300,
    "wait_timeout_ms": 30000,
    "metadata": { "agent_run": "abc123" }
  }'
```

### Request Body

`/run` accepts the same sandbox creation fields as `POST /api/v1/sandboxes`, plus:

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `command` | string | Yes | First command to execute after the sandbox reaches `running`. |
| `cwd` | string | No | Working directory for the command. Defaults to `/workspace`. |
| `timeout` | integer | No | Command timeout in milliseconds. |
| `wait_timeout_ms` | integer | No | Max time to wait for sandbox readiness before returning `504 SANDBOX_READY_TIMEOUT`. |

### Response  -  `201 Created`

```json
{
  "data": {
    "id": "sbx_01j9xr2t4fk8me3n5q",
    "state": "running",
    "ready": true,
    "template_id": "miosa-sandbox",
    "cpu_count": 2,
    "memory_mb": 4096
  },
  "exec": {

    "stderr": "",
    "exit_code": 0
  },
  "timings": {
    "server_wait_and_exec_ms": 512
  }
}
```

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 400 | `MISSING_PARAM` | `command` is missing. |
| 400 | `INVALID_TEMPLATE` | `template_id` is not recognized. |
| 402 | `INSUFFICIENT_CREDITS` | Not enough credits to provision the VM. |
| 429 | `SANDBOX_LIMIT_REACHED` | Tenant has reached the concurrent sandbox limit. |
| 409 | `SANDBOX_NOT_RUNNING` | The sandbox failed to reach a running state for exec. |
| 502 | `SANDBOX_BOOT_FAILED` | VM boot failed before the command could run. |
| 502 | `AGENT_UNAVAILABLE` | The sandbox agent was not reachable for exec. |
| 504 | `SANDBOX_READY_TIMEOUT` | The sandbox did not become ready before `wait_timeout_ms`. |

---

## Start a Template App

**`POST /api/v1/sandboxes/{id}/template/start`**

A sandbox created from a template that has a start command does not wait on the app at create: nothing has started it yet, so a `wait: true` create returns as soon as the sandbox is running instead of timing out.
The template's own readiness probe applies when you call `/template/start`; a probe you pass to create always wins.

After your platform writes generated files into `/workspace`, call this endpoint to run the selected template lifecycle. MIOSA runs the template install command, launches the start command in the background, stores PID/log paths, and returns the preview URL.
```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/template/start \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"install":true}'
```

Response:
```json
{
  "data": {
    "status": "started",
    "template_id": "nextjs",
    "workdir": "/workspace",
    "preview_port": 3000,
    "preview_url": "https://abc12345.sandbox.miosa.ai",
    "logs_path": "/tmp/miosa-run/template.log",
    "pid_path": "/tmp/miosa-run/template.pid",
    "artifact_paths": ["/workspace"]
  }
}
```

You can override `install_command`, `start_command`, `port`, or `workdir` in the request body when your generated project needs a custom command.

---

## Get Artifacts

**`GET /api/v1/sandboxes/{id}/artifacts`**

Returns the template artifact contract and current lifecycle metadata.
```bash
curl https://api.miosa.ai/api/v1/sandboxes/{id}/artifacts \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

The response includes `preview.url`, `preview.port`, artifact paths, and template lifecycle log/PID paths.

A create request with white-label attribution and env:

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "template_id": "miosa-sandbox",
    "workspace_slug": "acme-corp",
    "workspace_name": "Acme Corp",
    "project_slug": "lead-magnet",
    "project_name": "Lead Magnet",
    "external_workspace_id": "acct_123",
    "external_user_id": "user-456",
    "external_project_id": "project_789",
    "size": "small",
    "env": {"MY_VAR": "hello"}
  }'
```

---

## Custom templates

The canonical public V1 contract exposes only promoted templates returned by `GET /api/v1/templates`.
Standalone custom-template build, validation, log, retry, and cancellation endpoints are not part of that contract.
Do not make a public integration depend on those operations.

  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Get a Sandbox

**`GET /api/v1/sandboxes/{id}`**

### Auth

Bearer token required.

### Path Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `id` | string | Sandbox ID. |

### Response  -  `200 OK`

Full sandbox object (same shape as the create response with current `state`).

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 404 | `NOT_FOUND` | Sandbox does not exist or belongs to a different tenant. |
```bash
curl https://api.miosa.ai/api/v1/sandboxes/sbx_01j9xr2t4fk8me3n5q \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Destroy a Sandbox

**`DELETE /api/v1/sandboxes/{id}`**

Permanently deletes the sandbox, removes saved state, and settles billing. Use `POST /pause` when the user is done for now but may resume later.

### Auth

Bearer token required.

### Path Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `id` | string | Sandbox ID. |

### Response  -  `200 OK`
```json
{
  "id": "sbx_01j9xr2t4fk8me3n5q",
  "state": "destroyed",
  "total_runtime_sec": 42
}
```

### Errors

| Status | Code | Cause |
|--------|------|-------|
| 404 | `NOT_FOUND` | Sandbox does not exist or belongs to a different tenant. |
```bash
curl -X DELETE https://api.miosa.ai/api/v1/sandboxes/sbx_01j9xr2t4fk8me3n5q \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Pause and Resume

**`POST /api/v1/sandboxes/{id}/pause`** suspends guest vCPU execution for a running persistent sandbox while preserving its workspace.
It returns `409` if the sandbox is not running.

**`POST /api/v1/sandboxes/{id}/resume`** transitions a paused sandbox back to `running` and returns `409` if it is not paused.
Command and file operations can automatically resume a paused persistent sandbox before dispatch.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/pause \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/resume \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Idempotency-Key: resume-session-001"
```

---

## Restart

**`POST /api/v1/sandboxes/{id}/restart`** power-cycles a running sandbox under the same id.
It stops the sandbox keeping its disk, then boots that disk again.
Files, packages and enabled services survive; running processes do not.
Use it when a sandbox stops answering.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/restart \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

| Status | Code | Meaning |
|---|---|---|
| `200` | | Restarted: `{"id", "state": "running", "restarted": true}`. |
| `202` | | Still booting: `state` is `resuming` or `starting`; poll `GET /sandboxes/{id}`. |
| `409` | `SANDBOX_NOT_RUNNING` | Only a running sandbox restarts; use `POST /resume`. |
| `409` | `RESTART_NOT_POWER_CYCLED` | Its host stopped it with a memory checkpoint, so it was resumed from memory: running again, processes not restarted. |
| `502` | `RESTART_BOOT_FAILED` | It stopped and kept its disk but did not boot; `POST /resume` boots it again. |
| `503` | `RESTART_STOP_IN_PROGRESS` | It is still stopping; resume it once it is `stopped`. |

---

## Fork a Sandbox

**`POST /api/v1/sandboxes/{id}/fork`** creates a new sandbox from a copy-on-write snapshot of a running sandbox.
The optional body accepts `timeout_sec` and `template_id` for the new sandbox.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/fork \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: fork-experiment-001" \
  -d '{"timeout_sec":3600}'
```

Canonical public V1 exposes standalone snapshot create, list, inspect, delete, and restore operations.
Use fork when a customer needs an independent branch of current running state without managing the intermediate snapshot directly.

---

## Extend the Timeout

**`POST /api/v1/sandboxes/{id}/extend`**

Replaces the active-session timeout with `timeout_sec` from 1 through 86400.
The operation does not add duration to the old value.
Omitting the body preserves the current timeout.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/{id}/extend \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"timeout_sec":7200}'
```

---

## Get Sandbox Usage

**`GET /api/v1/sandboxes/{id}/usage`**

Returns measured runtime, provisioned vCPU time, active CPU, network traffic, estimated cost, and timeout visibility.

```json
{
  "data": {
    "sandbox_id": "3fa85f64-5717-4562-b3fc-2c963f66afa6",
    "state": "running",
    "runtime_sec": 47,
    "provisioned_vcpu_ms": 94000,
    "active_cpu_ms": 12000,
    "network_ingress_bytes": 2048,
    "network_egress_bytes": 4096,
    "measurement_status": {
      "active_cpu": "measured",
      "network": "measured",
      "provisioned_resources": "measured"
    },
    "estimated_cost_cents": 1,
    "timeout_sec": 3600,
    "timeout_remaining_ms": 3553000
  }
}
```

Interpret nullable measurements through `measurement_status`.
`unavailable` means no trustworthy value exists and the related field is `null`, not zero.
`stale` means the retained value is not current and must be labeled as such.
`timeout_remaining_ms` can be `null` before start or when timeout enforcement is disabled.

# Services API

URL: https://miosa.ai/docs/api-reference/services
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/services
Source: src/routes/docs/api-reference/services/+page.md
Description: API reference for managing long-running systemd services inside MIOSA computers.

Services are persistent processes managed by systemd inside a computer. Use them for web servers, background workers, databases, or any daemon that should survive across exec calls and restart automatically on failure.

Base path: `/api/v1/computers/{id}/services`

Services map directly to systemd unit files (`/etc/systemd/system/miosa-{name}.service`) managed by the computer command service. The computer must be **running** to interact with services.

---

## Quick Start
```typescript

const client = new Miosa();

// Register and start a web server
const svc = await client.services.create(computerId, {
  name: 'webserver',
  command: 'python3 -m http.server 8080',
  cwd: '/workspace/app',
  restart: 'always',
});

console.log(svc.status); // "starting"

// Check status later
const updated = await client.services.get(computerId, svc.id);
console.log(updated.status); // "running"
```
```bash
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/services \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "webserver",

## Common Recipes

### Deploy a Node.js app as a service
```typescript
// Upload app files first
await client.files.write(computerId, {
  path: '/workspace/app/server.js',
  content: serverJsContent,
});

// Register and start
const svc = await client.services.create(computerId, {
  name: 'node-app',
  command: 'node /workspace/app/server.js',
  env: { PORT: '3000' },
  restart: 'on-failure',
});
```

### Wait until a service is running
```python

svc = client.services.create(computer_id, name="worker", command="/usr/bin/worker")
while svc.status == "starting":
    time.sleep(1)
    svc = client.services.get(computer_id, svc.name)

if svc.status != "running":
    raise RuntimeError(f"Service failed to start: {svc.status}")
```

### Check for failed services in a fleet
```typescript
const computers = await client.computers.list();
for (const computer of computers.data) {
  if (computer.status !== 'running') continue;
  const services = await client.services.list(computer.id);
  const failed = services.data.filter(s => s.status === 'failed');
  if (failed.length > 0) {
    console.log(`${computer.name}: ${failed.length} failed services`);
  }
}
```

# Snapshots API

URL: https://miosa.ai/docs/api-reference/snapshots
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/snapshots
Source: src/routes/docs/api-reference/snapshots/+page.md
Description: API reference for creating, listing, and restoring microVM snapshots (checkpoints).

Snapshots capture the full in-memory state of a running computer  -  CPU state, RAM, and filesystem  -  and store it durably. Restore a snapshot to spin up an identical computer in seconds.

This page documents desktop Computer snapshots only.
Canonical sandbox V1 does not expose direct snapshot CRUD; use [Persistence, pause, and forks](/docs/develop/snapshots/) and the [fork endpoint](/docs/api-reference/sandboxes/#fork-a-sandbox).

Base path: `/api/v1/computers/{id}/snapshots`

Snapshots require the computer to be **running**. Creating a snapshot does not stop the computer.

---

## Quick Start
```typescript

const client = new Miosa();

// Create a snapshot
const snap = await client.snapshots.create(computerId, {
  comment: 'before-deploy-v2',
});

// Poll until ready
let status = snap.status;
while (status !== 'ready') {
  await new Promise(r => setTimeout(r, 3000));
  const updated = await client.snapshots.get(computerId, snap.id);
  status = updated.status;
}

// Restore  -  creates a new computer from the snapshot
const restored = await client.snapshots.restore(computerId, snap.id);
console.log(`Restored computer: ${restored.id}`);
```
```bash
# Create a snapshot
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/snapshots \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"comment": "before-deploy-v2"}'
```

| Parameter | Type | Description |
|-----------|------|-------------|
| `id` | UUID | Computer ID |
| `snap_id` | UUID | Snapshot ID |

### Response  -  `200 OK`

Full snapshot object (same shape as create response).

### Errors

| Status | Error | Cause |

---

## Delete a Snapshot

**`DELETE /api/v1/computers/{id}/snapshots/{snap_id}`**

Soft-deletes the snapshot (transitions to `"deleted"` status). S3 objects are cleaned up asynchronously.

### Response  -  `200 OK`
```json
{
  "data": {
    "id": "...",
    "status": "deleted"
  }
}
```

### Errors

| Status | Error | Cause |
|--------|-------|-------|
| 404 | `snapshot not found` | Does not exist |
| 409 | `snapshot is not in a deletable state` | Snapshot is being restored |
```bash
curl -X DELETE https://api.miosa.ai/api/v1/computers/{id}/snapshots/{snap_id} \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Restore from Snapshot

**`POST /api/v1/computers/{id}/restore/{snap_id}`**

    "status": "provisioning",
    "size": "small"
  },
  "snapshot": {
    "id": "snap-uuid",
    "status": "restoring"
  }
}
```

### Errors

| Status | Error | Cause |
|--------|-------|-------|
| 404 | `snapshot not found` | Does not exist |
| 409 | `snapshot is not ready` | Snapshot must be in `ready` state |
```bash
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/restore/{snap_id} \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## SSE Progress Stream

**`GET /api/v1/computers/{id}/snapshots/{snap_id}/events`**

Subscribe to real-time snapshot progress. Requires a short-lived ticket rather than a Bearer token (browsers cannot set Authorization on EventSource connections).

### Event Types

| Event | Description |
|-------|-------------|
| `snapshot_creating` | VM writing memory and VM state to disk |
| `snapshot_uploading` | Compressing and uploading to object storage |
| `snapshot_ready` | Upload complete; snapshot is usable |
| `snapshot_failed` | Unrecoverable error  -  see `error` field |

---

## Common Recipes

### Automated checkpoint before risky operations
```python
from miosa import Miosa

client = Miosa()

snap = client.snapshots.create(computer_id, comment="pre-migration")
while snap.status not in ("ready", "failed"):
    time.sleep(2)
    snap = client.snapshots.get(computer_id, snap.id)

if snap.status == "failed":
    raise RuntimeError(f"Snapshot failed: {snap.error}")

# Proceed with risky operation knowing you can restore
do_migration(computer_id)
```

### Snapshot-based parallelism (clone a baseline)
```typescript
// Build a baseline environment once, clone it N times for parallel jobs
const baseline = await client.snapshots.create(setupComputerId, {
  comment: 'baseline-env',
});

// Each restore creates an independent computer from the same state
const workers = await Promise.all(
  Array.from({ length: 5 }, () =>
    client.snapshots.restore(setupComputerId, baseline.id)
  )
);
```

# Streaming Exec API

URL: https://miosa.ai/docs/api-reference/streaming-exec
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/streaming-exec
Source: src/routes/docs/api-reference/streaming-exec/+page.md
Description: API reference for streaming command output in real-time from MIOSA computers via SSE.

Streaming exec runs a command on a computer and delivers output line-by-line via Server-Sent Events. Use it for long-running builds, installs, or any command where you want incremental output rather than waiting for completion.

Base path: `/api/v1/computers/{id}/exec/stream`

Standard `POST /computers/{id}/exec` waits for the command to finish before returning. Streaming exec is better for commands that run longer than a few seconds or that you want to monitor interactively.

---

## Quick Start
```typescript

const client = new Miosa();

// Stream a long-running build
for await (const event of client.exec.stream(computerId, {
  command: 'pip install torch',
  timeout: 300,
})) {
  if (event.type === 'output') {
    process.stdout.write(event.data.line);
  } else if (event.type === 'exit') {
    console.log(`Exit code: ${event.data.exitCode}`);
    break;
  }
}
```
```bash
# Obtain a streaming ticket first, then connect
TICKET=$(curl -s -X POST https://api.miosa.ai/api/v1/computers/{id}/exec/stream \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "pip install torch", "timeout": 300}' | jq -r .ticket)

curl -N "https://api.miosa.ai/api/v1/computers/{id}/exec/stream/events?ticket=$TICKET" \
  -H "Accept: text/event-stream"
```

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `POST` | `/computers/{id}/exec/stream` | Start a streaming exec and obtain a ticket |
| `GET` | `/computers/{id}/exec/stream/events` | SSE stream (requires ticket) |
| `POST` | `/computers/{id}/exec` | Non-streaming exec (waits for completion) |
| `POST` | `/computers/{id}/exec/python` | Non-streaming Python exec |

---

## Start Streaming Exec

**`POST /api/v1/computers/{id}/exec/stream`**

Starts the command and returns a short-lived ticket for the SSE stream.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `command` | string | Yes | Shell command to execute |
| `timeout` | integer | No | Timeout in seconds (default: 30, max: 86400) |
| `shell` | string | No | Shell to use (default: `/bin/bash`) |

### Response  -  `202 Accepted`
```json
{
  "ticket": "exec_short_lived_token",
  "expires_at": 1712700060,
  "stream_url": "/api/v1/computers/{id}/exec/stream/events?ticket=exec_short_lived_token"
}
```

The ticket expires in 60 seconds  -  open the EventSource connection immediately.

### Errors

| Status | Error | Cause |
|--------|-------|-------|
| 409 | `COMPUTER_NOT_RUNNING` | Computer is not running |
| 502 | `AGENT_UNAVAILABLE` | In-VM agent unreachable |
```bash
curl -X POST https://api.miosa.ai/api/v1/computers/{id}/exec/stream \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command": "npm install", "timeout": 120}'
```

---

## Connect to SSE Stream

**`GET /api/v1/computers/{id}/exec/stream/events?ticket={ticket}`**

### Event Types

| Event | Payload Fields | Description |
|-------|---------------|-------------|
| `output` | `line`, `stream` | A line of stdout or stderr |
| `exit` | `exit_code`, `duration_ms` | Command finished; stream closes after this |
| `timeout` | `timeout_seconds` | Command killed after timeout |
| `error` | `message` | Internal error before command started |

### Event Payload Examples
```

event: output
data: {"line": "Collecting torch\n", "stream": "stdout"}

event: output
data: {"line": "  Downloading torch-2.3.0-...\n", "stream": "stdout"}

event: exit
data: {"exit_code": 0, "duration_ms": 45312}
```

### `stream` Values

| Value | Description |
|-------|-------------|
| `stdout` | Standard output |
| `stderr` | Standard error |
```javascript
// Browser
const es = new EventSource(`/api/v1/computers/${id}/exec/stream/events?ticket=${ticket}`);

es.addEventListener('output', e => {
  const { line, stream } = JSON.parse(e.data);
  console.log(`[${stream}] ${line}`);
});

es.addEventListener('exit', e => {
  const { exit_code } = JSON.parse(e.data);
  console.log(`Exited with code ${exit_code}`);
  es.close();
});

es.addEventListener('error', () => {
  // Connection dropped or ticket expired
  es.close();
});
```

---

## Comparison: Streaming vs Non-Streaming

| Aspect | `POST /exec` | `POST /exec/stream` |
|--------|-------------|---------------------|
| Response timing | After command completes | Immediate (ticket) |
| Output delivery | All at once | Line by line via SSE |
| Max timeout | 86400 s | 86400 s |
| Best for | Quick commands | Long builds, installs |
| SDK method | `exec.run()` | `exec.stream()` |

---

## Common Recipes

### Monitor a build
```python
for event in client.exec.stream(computer_id, command="make build", timeout=300):
    if event.type == "output":
        print(event.data["line"], end="")
    elif event.type == "exit":
        if event.data["exit_code"] != 0:
            raise RuntimeError(f"Build failed with exit code {event.data['exit_code']}")
        print("Build succeeded")
        break
```

### Capture both streams separately
```typescript
const stdout: string[] = [];
const stderr: string[] = [];

for await (const event of client.exec.stream(computerId, { command: 'myapp 2>&1 | tee /tmp/output.log' })) {
  if (event.type === 'output') {
    if (event.data.stream === 'stdout') stdout.push(event.data.line);
    else stderr.push(event.data.line);
  } else if (event.type === 'exit') {
    break;
  }
}
```

### Timeout handling
```python
try:
    for event in client.exec.stream(computer_id, command="long-task", timeout=60):
        if event.type == "timeout":
            print(f"Command killed after {event.data['timeout_seconds']}s")
            break
        elif event.type == "exit":
            break
except Exception as e:
    print(f"Stream error: {e}")
```

---

## Sandbox streaming exec

Sandboxes stream command output directly over SSE, without a separate ticket step.

**`POST /api/v1/sandboxes/{id}/exec/stream`**

Runs a command and streams stdout/stderr events as Server-Sent Events. Use this for installer output, long-running agent tasks, and build logs that should show progress before the command exits. Request body is the same as `/exec`.

```bash
curl -N -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_01j9xr2t4fk8me3n5q/exec/stream \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Accept: text/event-stream" \
  -H "Content-Type: application/json" \
  -d '{"command":"npm install && npm run build","working_dir":"/workspace","timeout":300}'
```

Example events:
```text
event: stdout
data: {"line":"added 342 packages"}

event: exit
data: {"exit_code":0}
```

# Tenant Events (SSE) API

URL: https://miosa.ai/docs/api-reference/tenant-events
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/tenant-events
Source: src/routes/docs/api-reference/tenant-events/+page.md
Description: Subscribe to a real-time server-sent event stream of all tenant-wide platform events.

The tenant events stream delivers real-time Server-Sent Events (SSE) for all activity across your tenant  -  sandbox lifecycle changes, deployments, webhook deliveries, and more. Subscribe once and receive events for all your resources.

Base path: `/api/v1/events/stream`

This endpoint uses `text/event-stream` (SSE). Set `Accept: text/event-stream` on your request, or use a native `EventSource` client.

The `Authorization` header cannot be set by browser `EventSource`. Use a server-side client or pass an SSE ticket obtained from `POST /api/v1/auth/sse-ticket` for browser usage.

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/events/stream` | Open tenant-wide SSE event stream |

---

## Open Event Stream

**`GET /api/v1/events/stream`**

Upgrades to an SSE stream. The connection stays open until the client disconnects or the server closes it. A `: heartbeat` comment is sent every 15 seconds to keep the connection alive through proxies.

### Auth

```
Authorization: Bearer msk_...
```

### Query Parameters

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `types` | string | No | Comma-separated glob patterns to filter events (e.g. `sandbox.*,webhook.delivered`) |

### Response  -  `200 OK` (`text/event-stream`)

Each event is a standard SSE frame:

```
id: evt_01hwxyz...
event: sandbox.ready
data: {"type":"sandbox.ready","id":"sbx_abc123","status":"running","tenant_id":"...","ts":"2026-05-26T10:14:23Z"}

id: evt_01hwyza...
event: deployment.succeeded
data: {"type":"deployment.succeeded","id":"dep_xyz456","url":"https://my-app.miosa.app","ts":"2026-05-26T10:15:01Z"}

: heartbeat
```

### Event Shape

All events share a common envelope:

```json
{
  "type": "sandbox.ready",
  "id": "sbx_abc123",
  "tenant_id": "ten_...",
  "ts": "2026-05-26T10:14:23Z"
}
```

Additional fields vary by event type (see table below).

---

## Event Types

### Sandbox Events

| Type | Description | Extra Fields |
|------|-------------|-------------|
| `sandbox.created` | Sandbox provisioned | `image`, `workspace_id` |
| `sandbox.ready` | Sandbox reached `running` status | `status` |
| `sandbox.error` | Sandbox failed to start | `error`, `reason` |
| `sandbox.destroyed` | Sandbox deleted |  -  |
| `sandbox.paused` | Sandbox vCPUs suspended |  -  |
| `sandbox.resumed` | Sandbox vCPUs resumed |  -  |

### Computer Events

| Type | Description | Extra Fields |
|------|-------------|-------------|
| `computer.created` | Computer provisioned | `size`, `workspace_id` |
| `computer.running` | Computer reached `running` status |  -  |
| `computer.stopped` | Computer stopped |  -  |
| `computer.deleted` | Computer deleted |  -  |

### Deployment Events

| Type | Description | Extra Fields |
|------|-------------|-------------|
| `deployment.build_started` | Build job enqueued | `version_id` |
| `deployment.succeeded` | Build completed and promoted | `url`, `version_id` |
| `deployment.failed` | Build or promotion failed | `error` |
| `deployment.rollback` | Version rolled back | `from_version`, `to_version` |

### Webhook Events

| Type | Description | Extra Fields |
|------|-------------|-------------|
| `webhook.delivered` | Outgoing webhook POST succeeded | `webhook_id`, `status_code` |
| `webhook.failed` | Outgoing webhook POST failed | `webhook_id`, `attempt`, `error` |

### Filtering with `types`

Pass a comma-separated list of glob patterns. The `*` wildcard matches any suffix segment:

```
?types=sandbox.*           # all sandbox events
?types=sandbox.*,computer.running
?types=deployment.succeeded,deployment.failed
```

An empty `types` parameter (or no parameter) delivers all events.

---

## Reconnection

On disconnect, reconnect using the `Last-Event-ID` header set to the last `id` you received. The server will resume from that cursor, replaying up to 60 seconds of backlogged events.

```
GET /api/v1/events/stream
Authorization: Bearer msk_...
Last-Event-ID: evt_01hwxyz...
```

---

## Examples

```bash
# All events

# Tenant Preview Domain API

URL: https://miosa.ai/docs/api-reference/tenant-preview-domain
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/tenant-preview-domain
Source: src/routes/docs/api-reference/tenant-preview-domain/+page.md
Description: Configure a custom apex domain for sandbox preview URLs (white-label).

The preview domain API lets you map your own apex domain (e.g. `example.com`) to sandbox preview URLs. When configured, sandboxes created under your tenant will be accessible at `{sandbox-slug}.{your-domain}` instead of the default `*.sandbox.miosa.ai`.

**Auth note:** These endpoints accept both `msk_*` API keys and JWT tokens. This matters for white-label integrations where you programmatically manage the domain from a backend service.

Only apex domains are accepted (e.g. `example.com`, not `app.example.com` or `https://example.com`). Wildcard and subdomain inputs are rejected with `422 invalid_domain`.

---

## Endpoints

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/tenant/preview-domain` | Get current domain and verification status |
| `PUT` | `/api/v1/tenant/preview-domain` | Set or replace the preview domain |
| `POST` | `/api/v1/tenant/preview-domain/verify` | Recheck DNS verification |
| `DELETE` | `/api/v1/tenant/preview-domain` | Remove the custom domain |

---

## Get Preview Domain

**`GET /api/v1/tenant/preview-domain`**

Returns the configured domain and its DNS verification status.

### Auth

```
Authorization: Bearer msk_...
```

### Response  -  `200 OK` (domain configured)

```json
{
  "preview_domain": "example.com",
  "status": "configured",
  "dns_instructions": {
    "type": "CNAME",
    "name": "*.example.com",
    "value": "proxy.miosa.ai"
  }
}
```

### Response  -  `200 OK` (not configured)

```json
{
  "preview_domain": null,
  "default_domain": "miosa.ai",
  "status": "not_configured",
  "dns_instructions": null
}
```

| Field | Type | Description |
|-------|------|-------------|
| `preview_domain` | string\|null | Configured apex domain, or `null` |
| `default_domain` | string | Fallback domain used when no custom domain is set |
| `status` | string | `"not_configured"`, `"pending_dns"`, or `"configured"` |
| `dns_instructions` | object\|null | CNAME record to add at your DNS registrar |

---

## Set Preview Domain

**`PUT /api/v1/tenant/preview-domain`**

Sets or replaces the custom preview domain. DNS verification is asynchronous  -  status transitions from `pending_dns` to `configured` once the CNAME resolves correctly.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `preview_domain` | string | Yes | Apex domain (e.g. `"example.com"`) |

```json
{
  "preview_domain": "example.com"
}
```

### Response  -  `200 OK`

```json
{
  "preview_domain": "example.com",
  "status": "pending_dns",
  "dns_status": "pending",
  "dns_instructions": {
    "type": "CNAME",
    "name": "*.example.com",
    "value": "proxy.miosa.ai"
  }
}
```

### DNS Setup

Add a wildcard CNAME at your registrar:

| Type | Name | Value |
|------|------|-------|
| `CNAME` | `*` (or `*.example.com`) | `proxy.miosa.ai` |

---

## Verify DNS

**`POST /api/v1/tenant/preview-domain/verify`**

Triggers an immediate DNS re-check. Returns the current verification status without waiting for the background poller.

### Response  -  `200 OK`

```json
{
  "preview_domain": "example.com",
  "status": "configured",
  "dns_status": "verified"
}
```

---

## Delete Preview Domain

**`DELETE /api/v1/tenant/preview-domain`**

Removes the custom domain. Sandbox preview URLs revert to `*.sandbox.miosa.ai`.

### Response  -  `200 OK`

```json
{
  "preview_domain": null,
  "status": "removed"
}
```

---

## Errors

| Status | Code | Cause |
|--------|------|-------|
| 400 | `preview_domain is required` | Missing body field |
| 422 | `invalid_domain` | Protocol prefix, wildcard, path, or subdomain detected |
| 404 | `tenant not found` | Tenant does not exist |

# API Reference / Versions

URL: https://miosa.ai/docs/api-reference/versions
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/versions
Source: src/routes/docs/api-reference/versions/+page.md
Description: Immutable deployment version sub-resource. List, get, promote, archive.

A **Deployment Version** is the immutable record of one publish. See [Versions](/docs/docker-host/versions/) for the conceptual model.

## Endpoints
```http
GET  /api/v1/deployments/:id/versions
GET  /api/v1/deployments/:id/versions/:version_id
POST /api/v1/deployments/:id/versions/:version_id/promote
```

## List
```http
GET /api/v1/deployments/:id/versions
GET /api/v1/deployments/:id/versions?state=ready
GET /api/v1/deployments/:id/versions?workspace_id=550e8400-e29b-41d4-a716-446655440000
GET /api/v1/deployments/:id/versions?external_workspace_id=acct_123
GET /api/v1/deployments/:id/versions?limit=50
```

Response:
```json
{
  "data": [
    {
      "id": "ver_...",
      "deployment_id": "dep_...",
      "version_number": 17,
      "kind": "static",
      "state": "ready",
      "artifact_sha256": "a5e6f0c1...",
      "source_sha256": "f1a3b8c2...",

      "created_at": "2026-05-14T18:19:48Z"
    }
  ],
  "total": 17
}
```

## Get
```http
GET /api/v1/deployments/:id/versions/:version_id
```

Returns the full version row including `artifact_manifest`, `runtime_image`, `runtime_command`, `runtime_port`, `health_check_path`, `build_log_uri`.

## Promote

Make a specific ready version the active one for the deployment.
```http
POST /api/v1/deployments/:id/versions/:version_id/promote
```

Body: empty, or optionally `{ "environment": "production" }`.

Scopes: `deployments:write`. Requires `Idempotency-Key` for safety on retries.

Promotion is different from publish:
- **Publish** creates a new version from a sandbox source.
- **Promote** points an existing ready version as active in an environment.

Use promote for canary / staged rollouts: publish to a non-production environment first, validate, then promote to production.

## States

| State | Meaning |
|---|---|
| `created` | Row exists, build not started |
| `building` | Build in progress |
| `ready` | Build succeeded, artifact uploaded, promotable |
| `failed` | Build or health check failed |
| `archived` | Promoted-out-of; still bootable for rollback |

State transitions are one-way. Once `ready` or `failed`, a version stays that way.

## Permissions

| Action | Scope |
|---|---|
| List, Get | `deployments:read` |
| Promote | `deployments:write` |

# Webhooks API

URL: https://miosa.ai/docs/api-reference/webhooks
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/webhooks
Source: src/routes/docs/api-reference/webhooks/+page.md
Description: Subscribe to platform lifecycle events via outgoing HTTP callbacks with HMAC signature verification.

Webhooks fire outgoing HTTP POST requests to your endpoint when platform events occur  -  sandbox lifecycle changes, deployment completions, billing events, and more. Each delivery is signed with HMAC-SHA256 so you can verify authenticity.

Base path: `/api/v1/webhooks`

The webhook `secret` is returned **only once**  -  in the response to `POST /webhooks`. Store it immediately in a secure location. It cannot be retrieved later (only a masked preview is shown afterward).

---

## Endpoints

| Method | Path | Description |

    }
  ]
}
```

---

## Create a Webhook

**`POST /api/v1/webhooks`**

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `url` | string | Yes | HTTPS endpoint to POST events to |
| `name` | string | No | Human-readable label |
| `events` | string[] | No | Event type filter; empty = all events |
| `headers` | object | No | Extra headers to include in deliveries |
| `retry_count` | integer | No | Consecutive failed deliveries before the webhook is marked `failed` (0-10, default `3`) |
| `metadata` | object | No | Arbitrary key-value metadata |

```json
{
  "url": "https://api.myapp.com/hooks/miosa",
  "name": "Sandbox lifecycle",
  "events": ["sandbox.created", "sandbox.ready", "sandbox.error", "sandbox.destroyed"],
  "retry_count": 3
}
```

### Response  -  `201 Created`

```json
{
  "data": {
    "id": "wh_01hwxyz...",
    "name": "Sandbox lifecycle",
    "url": "https://api.myapp.com/hooks/miosa",
    "events": ["sandbox.created", "sandbox.ready", "sandbox.error", "sandbox.destroyed"],
    "secret": "sk_live_abc123def456...",
    "secret_preview": "sk_live_••••••••3456",
    "retry_count": 3,
    "created_at": "2026-05-26T10:14:23Z",
    "updated_at": "2026-05-26T10:14:23Z"
  }
}
```

The `secret` field appears only in this response. Save it securely.

---

## Update a Webhook

**`PATCH /api/v1/webhooks/{id}`**

Partial update  -  include only fields you want to change.

### Request Body

Same fields as create, all optional.

### Response  -  `200 OK`

Webhook object without the `secret` field.

---

## Delete a Webhook

**`DELETE /api/v1/webhooks/{id}`**

### Response  -  `204 No Content`

---

## Send a Test Delivery

**`POST /api/v1/webhooks/{id}/test`**

Sends a synthetic `webhook.test` event to the configured URL to verify connectivity and signature verification.

The attempt is recorded in the delivery log like any other delivery, marked as a test, so what the endpoint received is always visible at `GET /api/v1/webhooks/{id}/deliveries`. A test does not count toward `retry_count` and never moves the webhook to `failed`: a test against an endpoint that is temporarily down must not pause a live subscription.

### Response  -  `200 OK`

```json
{
  "delivered": true,
  "status_code": 200,
  "duration_ms": 143
}
```

---

## List Deliveries

**`GET /api/v1/webhooks/{id}/deliveries`**

Returns recent delivery attempts with status codes and timing.

### Response  -  `200 OK`

```json
{
  "data": [
    {
      "id": "del_01hwyza...",
      "event_type": "sandbox.ready",
      "status": "delivered",
      "status_code": 200,
      "attempt": 1,
      "duration_ms": 98,
      "delivered_at": "2026-05-26T10:14:24Z"
    },
    {
      "id": "del_01hwyzb...",
      "event_type": "sandbox.created",
      "status": "failed",
      "status_code": 500,
      "attempt": 3,
      "duration_ms": 5012,
      "delivered_at": "2026-05-26T10:14:20Z"
    }
  ]
}
```

---

## Signature Verification

Every delivery includes an `X-Miosa-Signature` header. Verify it on your server before trusting the payload:

```
X-Miosa-Signature: sha256=<hex_digest>
```

Compute the expected signature:

```
hmac = HMAC-SHA256(secret, raw_request_body_bytes)
expected = "sha256=" + hex(hmac)
assert constant_time_equals(expected, request.headers["X-Miosa-Signature"])
```

Always compare signatures using a constant-time function to prevent timing attacks. Never use `==` for string comparison.

### Example verification (Python)

```python

def verify_signature(secret: str, body: bytes, header: str) -> bool:
    expected = "sha256=" + hmac.new(
        secret.encode(), body, hashlib.sha256
    ).hexdigest()
    return hmac.compare_digest(expected, header)
```

### Example verification (TypeScript)

```typescript

function verifySignature(secret: string, body: Buffer, header: string): boolean {
  const expected = 'sha256=' + createHmac('sha256', secret).update(body).digest('hex');
  return timingSafeEqual(Buffer.from(expected), Buffer.from(header));
}
```

---

## Retry Policy

Failed deliveries are retried on a fixed backoff schedule:

| Attempt | Delay |
|---------|-------|
| 1 (initial) | Immediate |
| 2 | 1 minute |
| 3 | 5 minutes |
| 4 | 30 minutes |
| 5 | 1 hour |
| 6 | 2 hours |
| 7 | 4 hours |
| 8 | 8 hours |

MIOSA makes up to eight delivery attempts over roughly 15.5 hours (within a 24-hour window), then drops the event.

A delivery is considered failed if your endpoint returns a non-2xx status code or does not respond within 10 seconds. `retry_count` (0-10, default 3) is the number of consecutive failed deliveries after which MIOSA marks the webhook `failed`; it is not the per-delivery retry cap. Set it to `0` to mark the webhook failed on the first failed delivery.

---

## Subscribed Event Types

`GET /api/v1/webhooks/events` returns this list, grouped by product surface. It is the same list the API validates a subscription against, so an event that is not here cannot be subscribed to.

`forge.*` payloads carry `repository_id`, `repository_slug` and `organization_slug`, so one subscription can route each event to the right repository.

`webhook.test` is the synthetic event sent by `POST /api/v1/webhooks/:id/test`. It is not subscribable and appears in the delivery log as a test delivery.

Subscribe to all events by omitting the `events` field. Subscribe to a subset by listing specific event types.

# Workspaces API

URL: https://miosa.ai/docs/api-reference/workspaces
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/api-reference/workspaces
Source: src/routes/docs/api-reference/workspaces/+page.md
Description: API reference for creating and managing MIOSA workspaces - the customer/client layer inside an organization.

Workspaces group resources inside an organization. In a white-label platform, a workspace usually represents one downstream customer or client, such as `Acme Corp` inside the `Lumen` organization. Projects live inside workspaces, and sandboxes, computers, deployments, databases, storage buckets, volumes, functions, jobs, and domains belong to projects.

Base path: `/api/v1/workspaces`

A **default** workspace is created automatically when you sign up. Resources are assigned to the default workspace and its default project unless you specify workspace/project ownership at creation time.

---

## Quick Start
```typescript

const client = new Miosa(); // reads MIOSA_API_KEY

// Create a workspace for a downstream customer
const ws = await client.workspaces.create({
  name: 'Acme Corp',
  slug: 'acme-corp',
  externalWorkspaceId: 'acct_123',
});

// Create a computer inside a project in that workspace
const computer = await client.computers.create({
  name: 'workspace-builder',
  template_type: 'miosa-desktop',
  workspaceId: ws.id,
  projectSlug: 'lead-magnet',
  projectName: 'Lead Magnet',
});

// List computers in the workspace
const { data } = await client.workspaces.listComputers(ws.id);
```
```bash
# curl equivalent
curl -X POST https://api.miosa.ai/api/v1/workspaces \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "Acme Corp", "slug": "acme-corp", "external_workspace_id": "acct_123"}'
```

  -d '{"name": "production-us-east"}'
```

---

## Delete a Workspace

**`DELETE /api/v1/workspaces/{id}`**

```

---

## Update Workspace Settings

**`PUT /api/v1/workspaces/{id}/settings`**

Applies resource limits and default preferences for the workspace. These limits cap what any computer inside the workspace can do. Tenant-level limits still apply as a ceiling.

### Request Body

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `max_computers` | integer | No | Maximum number of computers allowed in this workspace. `null` = no workspace-level cap (tenant limit applies). |
| `max_computer_size` | string | No | Maximum `size` value a computer in this workspace may be created with: `"small"`, `"medium"`, or `"large"`. |
| `default_computer_size` | string | No | Default `size` applied when creating a computer without an explicit `size`. |
| `default_auto_stop_seconds` | integer | No | Auto-stop idle timeout (seconds) applied to new computers by default. `0` = no auto-stop. |
| `allowed_template_types` | string[] | No | Allowlist of template names that can be used in this workspace. Empty array = all templates allowed. |
| `monthly_spend_cap_cents` | integer | No | Monthly cap, in credits (1 credit = 1 US cent), on hosted sandbox spend in this workspace. `null` clears it. |
| `monthly_total_spend_cap_cents` | integer | No | Monthly cap, in credits, on everything settled against this workspace: sandboxes, computers, deployments, databases, storage, snapshots, backups and functions. `null` clears it. |
| `spend_cap_action` | string | No | What reaching a cap does: `"pause"` (the default) refuses new resources in the workspace with HTTP 402 and stops what is running there, `"alert"` only sends threshold alerts. |
| `entity_spend_caps` | object | No | Monthly caps per `entity` tag, for example `{"customer-a": 5000}`. |

Nothing is destroyed and nothing resumes by itself. The setting is named `spend_cap_action`, not `action`.

### Response  -  `200 OK`
```json
{
  "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
  "settings": {
    "max_computers": 10,
    "max_computer_size": "large",
    "default_computer_size": "small",
    "default_auto_stop_seconds": 3600,
    "allowed_template_types": []
  },
  "updated_at": "2026-05-17T10:00:00Z"
}
```

---

## Domains

Workspaces do not own a preview domain. Preview domains are an organization
setting, and per-deployment custom domains are attached to the deployment:

- [Custom Domains API](/docs/api-reference/custom-domains/) - the organization preview domain and deployment/computer custom domains.

---

### Errors

| Status | Error | Cause |
|--------|-------|-------|
| 403 | `FORBIDDEN` | The caller is not an organization owner or admin (`Only workspace admins may update workspace limits`) |
| 403 | `forbidden` | Wrong tenant |
| 404 | `workspace not found` | Does not exist |
| 422 | `VALIDATION_FAILED` | Unknown size value or invalid limit |
| 422 | `UNKNOWN_WORKSPACE_SETTING` | A setting name the API does not know. The `message` names the closest accepted key (sending `action` answers `Did you mean "spend_cap_action"?`) and `allowed` lists every accepted setting. |
```bash
curl -X PUT https://api.miosa.ai/api/v1/workspaces/{id}/settings \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "max_computers": 10,
    "max_computer_size": "large",
    "default_auto_stop_seconds": 3600

  -H "Authorization: Bearer $MIOSA_API_KEY"
```

---

## Common Recipes

### Move all computers to a new workspace

Computers do not yet support a `move` operation on workspace assignment via `PATCH /computers/{id}`. Use the `POST /computers/{id}/move` endpoint instead:
```bash
curl -X POST https://api.miosa.ai/api/v1/computers/{computer_id}/move \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"workspace_id": "target-workspace-id"}'
```

### Enumerate all workspaces and their sizes
```typescript
const { data: workspaces } = await client.workspaces.list();
for (const ws of workspaces) {
  console.log(`${ws.name}: ${ws.computerCount} computers`);
}
```

### Default workspace ID lookup

If you need the default workspace ID programmatically:
```typescript
const { data } = await client.workspaces.list();
const defaultWs = data.find(ws => ws.isDefault);
console.log(defaultWs.id);
```

---

## Common Errors

| Status | Code | Cause |
|--------|------|-------|
| 403 | `forbidden` | Workspace belongs to a different tenant |
| 404 | `workspace not found` | Does not exist |
| 409 | `workspace has computers` | Cannot delete a workspace that contains computers |
| 422 | `VALIDATION_FAILED` | Name or slug failed schema validation |

# Authentication

URL: https://miosa.ai/docs/authentication
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/authentication
Source: src/routes/docs/authentication/+page.md
Description: How to authenticate with the MIOSA API using msk_ API keys or JWT tokens.

# Authentication

Every MIOSA API request carries a single `Authorization: Bearer &lt;token&gt;` header.
The token is either an **API key** (prefix `msk_`) or a **JWT** from `POST /auth/login`.

One key covers the entire platform  -  computers, desktop, files, exec, CUA agent,
OSA, credits, and (with the right role) admin. No separate keys for AI, no
per-product configuration.

## Credential hierarchy

Diagram:
graph TB
    MSK[msk_* workspace key] -->|server-side only| API[MIOSA API calls]
    MSK -->|mints via POST /api/v1/browser-tokens| BT[Browser token - scoped + short-lived]
    BT -->|browser only| EP[Specific sandbox endpoint]
    MSK -->|mints via POST /api/v1/auth/sse-ticket| ST[SSE ticket - single use]
    ST -->|EventSource| SS[SSE stream]
    MSK -->|mints via POST /api/v1/sandboxes/:id/preview-token| MP[mp_ Preview token]
    MP -->|iframe embed - no msk_ exposed| Preview[MiosaPreview component]
    MSK -->|mints via POST /api/v1/sandboxes/:id/shares| MS[ms_ Share token]
    MS -->|URL param - public read-only| ShareURL[Public share URL]

## API Keys

### Key format
```

msk_<role>_<random>
```

| Prefix | Role | Capabilities |
|--------|----------|---------------------------------------------------|
| `msk_u_...` | user | Compute, desktop, files, CUA, OSA, credits |
| `msk_a_...` | admin | Everything above **+** `/api/v1/admin/*` |
| `msk_p_...` | platform | Tenant-wide automation issued by the MIOSA platform |

The public self-service endpoint creates normal API-purpose keys.
Specialized operator or intelligence credentials use separate controlled flows.

### Creating an API key
```bash
curl -X POST https://api.miosa.ai/api/v1/api-keys \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Production SDK Key",
    "key_type": "user"
  }'
```
```json
{
  "data": {
    "id": "550e8400-e29b-41d4-a716-446655440000",
    "key": "msk_u_a1b2c3d4e5f6g7h8i9j0k1l2m3n4o5p6",
    "key_prefix": "msk_u_a1b2c3",
    "name": "Production SDK Key",
    "key_type": "user",
    "key_purpose": "api",
    "rate_limit_rpm": 600,
    "status": "active",
    "created_at": "2026-04-17T00:00:00Z"
  }
}
```

The raw key is **only returned once** at creation. Store it securely. If lost,
revoke it and create a new one  -  the original cannot be recovered.

Users can mint personal `user` keys.
Tenant owners and administrators can also mint `platform` keys for backend automation.
Admin keys remain operator-internal and are not created through the public self-service endpoint.

### Using an API key

Pass the key in the `Authorization` header:
```bash
curl https://api.miosa.ai/api/v1/computers \
  -H "Authorization: Bearer msk_u_a1b2c3d4e5f6..."
```

All five SDKs read `MIOSA_API_KEY` from the environment by default:

```python
  from miosa import Miosa

  # Explicit key
  client = Miosa(api_key="msk_u_...")

  # Or from environment: export MIOSA_API_KEY="msk_u_..."
  client = Miosa()
```

```ts

  // Explicit key
  const miosa = new Miosa({ apiKey: 'msk_u_...' });
```

```go

  // Explicit key
  client := miosa.NewClient("msk_u_...")

  // Or from environment
  client := miosa.NewClient(os.Getenv("MIOSA_API_KEY"))
```

```elixir
  # Explicit key
  client = Miosa.client("msk_u_...")

  # Or from environment
  client = Miosa.client(System.fetch_env!("MIOSA_API_KEY"))
```

```java

  MiosaClient miosa = new MiosaClient("msk_u_...");
```

### Managing keys

| Action | Endpoint |
|--------|----------|
| List your keys | `GET /api/v1/api-keys` |
| Create a key | `POST /api/v1/api-keys` |
| Revoke a key | `DELETE /api/v1/api-keys/{id}` |

Revoking a key flips its status to `revoked`. The change is cached and
enforced within seconds  -  subsequent requests return `401 Unauthorized`.
Revocation is irreversible; create a new key if you need access restored.

### Admin keys

`msk_a_*` keys unlock operator-admin endpoints.
`msk_p_*` keys are trusted tenant automation credentials, but they do not automatically make a caller a MIOSA operator.

User-role callers hitting an admin endpoint receive `403 Forbidden`.

Admin endpoints are operator-internal and not documented publicly.

## Preview tokens

Preview tokens (`mp_<base64url>`) are short-lived signed tokens for embedding a sandbox preview in an `<iframe>` without exposing an `msk_*` key to the browser.

Your backend mints a preview token server-side and passes it to the `` UI component. The component includes it automatically  -  no `Authorization` header needed in browser code.

### Minting a preview token

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/preview-token \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{"expires_in": 3600}'
```
```json
{
  "data": {
    "token": "mp_eyJhbGciOiJFZERTQSIs...",
    "expires_at": "2026-05-25T13:00:00Z",
    "sandbox_id": "sbx_abc123"
  }
}
```

```python
from miosa import Miosa

client = Miosa(api_key="msk_u_...")

preview = client.sandboxes.create_preview_token(
    sandbox_id="sbx_abc123",
    expires_in=3600,
)
# Pass preview.token to the browser  -  never the msk_ key.
```

```typescript

const miosa = new Miosa({ apiKey: 'msk_u_...' });

const preview = await miosa.sandboxes.createPreviewToken('sbx_abc123', {
  expiresIn: 3600,
});
// Pass preview.token to the browser  -  never the msk_ key.
```

In the browser, pass the token to the `` component:
```html

```

See [`` and other UI components](/docs/ui-components) and the [Preview Tokens API reference](/docs/api-reference/preview-tokens) for the full component API and token validation spec.

- **Format:** `mp_<base64url>`  -  signed, not opaque; do not attempt to decode.
- **TTL:** Default 1 hour; configurable via `expires_in` (max 24 hours).
- **Scope:** Read-only access to the specific sandbox's preview port. Cannot create or mutate resources.
- **Revocation:** Preview tokens cannot be individually revoked. Destroying the sandbox invalidates all outstanding tokens for it.

---

## Share tokens

Share tokens (`ms_<base64url>`) turn a sandbox preview into a public read-only URL that anyone with the link can visit  -  no MIOSA account required.

### Minting a share URL

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/shares \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{"expires_in": 86400}'
```
```json
{
  "data": {
    "token": "ms_eyJhbGciOiJFZERTQSIs...",
    "url": "https://sbx-abc123.sandboxes.miosa.ai?ms=ms_eyJhbGciOiJFZERTQSIs...",
    "expires_at": "2026-05-26T00:00:00Z",
    "sandbox_id": "sbx_abc123"
  }
}
```

```python
from miosa import Miosa

client = Miosa(api_key="msk_u_...")

share = client.sandboxes.create_share(
    sandbox_id="sbx_abc123",
    expires_in=86400,
)
print(share.url)  # Hand this URL to the end user.
```

```typescript

const miosa = new Miosa({ apiKey: 'msk_u_...' });

const share = await miosa.sandboxes.createShare('sbx_abc123', {
  expiresIn: 86400,
});
console.log(share.url); // Hand this URL to the end user.
```

- **Format:** `ms_<base64url>`  -  the token IS the URL query parameter (`?ms=ms_...`).
- **Access:** Public, read-only, unauthenticated  -  anyone with the URL can view the preview.
- **TTL:** Set via `expires_in` in seconds. No maximum enforced; omit for a non-expiring share.
- **Revocation:** `DELETE /api/v1/sandboxes/:id/shares/:share_id` revokes immediately.

See the [Sandbox Shares API reference](/docs/api-reference/sandbox-shares) and [Integrations: Preview Tokens](/docs/develop/previews).

## Token comparison

| Token | Scope | TTL | Who uses it |
|---|---|---|---|
| `msk_*` API key | Full workspace | Until revoked | Server |
| JWT | User session | ~1 h (refresh 7 d) | Server / browser (UI) |
| Browser token | Single sandbox | Configurable (default 1 h) | Browser |
| `mp_` Preview token | Single sandbox preview | Configurable (default 1 h) | Browser / iframe |
| `ms_` Share token | Single sandbox preview | Configurable | Anyone (unauthenticated) |

| Token | How to mint | Can revoke | Creates resources |
|---|---|---|---|
| `msk_*` API key | Dashboard or `POST /api/v1/api-keys` | Yes | Yes |
| JWT | `POST /api/v1/auth/login` | No (short TTL) | Yes |
| Browser token | `POST /api/v1/browser-tokens` | No (short TTL) | No |
| `mp_` Preview token | `POST /api/v1/sandboxes/:id/preview-token` | No | No |
| `ms_` Share token | `POST /api/v1/sandboxes/:id/shares` | Yes | No |

---

## White-label auth note

The `tenant.preview_domain.*` and `tenant.branding.*` configuration endpoints accept **both** `msk_*` API keys and JWTs. These are the only tenant-level config routes accessible with an API key  -  all other tenant administration routes require a JWT from an admin session.

```bash
# Setting a preview domain with an API key (allowed)
curl -X PUT https://api.miosa.ai/api/v1/tenant/preview-domain \
  -H "Authorization: Bearer msk_a_..." \
  -H "Content-Type: application/json" \
  -d '{"domain": "preview.yourdomain.com"}'

# Fetching tenant branding with an API key (allowed)
curl https://api.miosa.ai/api/v1/tenant/branding \
  -H "Authorization: Bearer msk_a_..."
```

See the [Tenant Preview Domain](/docs/api-reference/tenant-preview-domain) and [Tenant Branding](/docs/api-reference/tenant-branding) API references for the full configuration spec.

---

## JWT Tokens

JWT tokens are used by the MIOSA web UI and SSE ticket flows. They are issued
on login and carry user identity + tenant context.

### Obtaining a token
```bash
curl -X POST https://api.miosa.ai/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"email": "user@example.com", "password": "your_password"}'
```
```json
{
  "token": "eyJhbGciOiJIUzUxMiIs...",
  "refresh_token": "eyJhbGciOiJIUzUxMiIs...",
  "user": { "id": "...", "email": "user@example.com" }
}
```

### Token lifecycle

| Token | Lifetime | Refresh |
|-------|----------|---------|
| Access token | ~1 hour | Use refresh token |
| Refresh token | 7 days | Re-login required |
```bash
curl -X POST https://api.miosa.ai/api/v1/auth/refresh \
  -H "Content-Type: application/json" \
  -d '{"refresh_token": "eyJhbGciOiJIUzUxMiIs..."}'
```

For programmatic access, use **API keys**. JWTs are designed for browser
sessions and expire frequently.

## SSE streams

Server-Sent Event endpoints (CUA session events) cannot use a standard
`Authorization` header because `EventSource` does not support custom headers.
Instead, mint a one-time ticket first:
```bash
# 1. Ask for a ticket (Bearer-authed  -  API key or JWT both work)
curl -X POST \
  https://api.miosa.ai/api/v1/computers/{id}/cua/sessions/{session_id}/sse-ticket \
  -H "Authorization: Bearer msk_u_..."

# {"ticket":"sset_abc123","expires_in":3600,"session_id":"..."}

# 2. Open the stream with the ticket as a query param
curl https://api.miosa.ai/api/v1/computers/{id}/cua/sessions/{session_id}/events?ticket=sset_abc123
```

The ticket is single-use and expires after one hour.

## Rate limits

| Scope | Current default | Notes |
|-------|-------|--------|
| User API key | 600 requests per minute | Tenant and endpoint-family policy can lower it |
| Platform API key | 30,000 requests per minute | Restricted to tenant owners and administrators |
| Public auth endpoints | 60 requests per minute per IP | Individual auth actions may have separate controls |

When rate limited, the API returns `429 Too Many Requests` with a
`Retry-After` header.

Rate-limit status is surfaced in every response:
```

X-RateLimit-Limit: 600
X-RateLimit-Remaining: 587
X-RateLimit-Reset: 1712700060
```

## Error codes

| Status | Code | Meaning |
|--------|------|---------|
| 401 | `UNAUTHORIZED` | Missing / invalid / revoked credential |
| 403 | `FORBIDDEN` | Valid credential but insufficient role |
| 429 | `RATE_LIMITED` | Too many requests |

## Security best practices

1. **Never commit API keys** to version control.
2. **Use environment variables** or a secrets manager.
3. **Rotate keys** on exposure  -  revoke and create a new one.
4. **Scope by role**  -  hand out `msk_u_*` keys to most callers; reserve
   `msk_a_*` / `msk_p_*` for operational tooling.
5. **Separate keys for dev and prod**  -  easier to revoke blast radius.
6. **Restrict by IP** (admin keys)  -  pass `allowed_ips` when minting via
   `POST /admin/api-keys` to reject traffic from unexpected sources.

# Availability & Roadmap

URL: https://miosa.ai/docs/availability
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/availability
Source: src/routes/docs/availability/+page.md
Description: Current MIOSA product availability, what is generally available, what is in hardening, and what is planned next.

# Availability & Roadmap

This page gives customers a clean read on what is ready for production today, what is available for selected partners, and what is still on the roadmap.

Last updated: 2026-07-25.
We update this page when a platform capability changes release stage.

## Release stages

| Stage | Meaning |
|---|---|
| **Generally available** | Supported for production use with documented APIs and normal support paths. |
| **Partner preview** | Available to approved customers while we finish polish, SDK parity, or operating runbooks. |
| **In hardening** | Built or partially available, but not ready to promise as a stable public surface. |
| **Planned** | On the roadmap, not available for production use yet. |

## Generally available


    Create isolated Linux workspaces for code generation, build steps, test runs, long-running commands, file operations, and live previews.



    Expose a running process on a public preview URL, with private preview tokens for embedded product experiences.



    Turn a sandbox into a durable deployment version, promote it, list versions, and roll back when needed.



    Use Postgres, MySQL, Redis, Qdrant, object storage, per-project auth, and persistent volumes with credentials injected into runtime.



    Use external IDs, browser tokens, custom branding, preview domains, webhooks, and usage rollups to build MIOSA into your own product.


## Partner preview

These surfaces are being used with selected customers while we continue polishing public docs and SDK parity.

| Surface | Current scope |
|---|---|
| **Computers** | Full Linux desktops for browser automation, screenshot loops, and computer-use agents. |
| **Dynamic deployments** | Production server processes created from a sandbox publish. |
| **Docker Host** | Workspace-scoped container runtime for apps that need Docker, server processes, background workers, or database-backed production hosting. |
| **Tenant deployment domains** | Branded app domains for generated apps, separate from sandbox preview domains. Routing exists; tenant-level self-service remains operator-assisted while exact deployment domains are self-service. |
| **External computer providers** | Bring third-party computer providers into the same MIOSA computer abstraction. |
| **Evaluations** | Desktop and agent workflow benchmarks using reproducible tasks, traces, and scoring. |

## In hardening

| Area | Status |
|---|---|
| **Desktop computer provisioning** | Computers preserve disks and snapshots across stop, resume, and failed recovery. Start latency and stream readiness continue to be hardened. |
| **Dynamic runtime routing** | Dynamic runtimes keep the active healthy version serving while candidates build. Route evidence and automated recovery continue to be hardened. |
| **Docker Host fleet maintenance** | Host upgrades preserve deployment records and desired state, restore desired-running apps, and verify workloads before returning a host to active service. |
| **Customer-cloud regions** | AWS and Google Cloud foundations exist, but production placement remains gated on a real provider canary and per-host acceptance evidence. |
| **Managed data recovery** | Database IDs, credentials, volumes, bindings, and desired state survive host maintenance. Recovery visibility continues to be expanded across product surfaces. |
| **Deployment proof** | CLI, TypeScript SDK, Python SDK, and Go SDK expose proof checks. Java and Elixir parity is still in progress. |
| **SDK parity** | Python and TypeScript are deepest today. Go, Java, Elixir, and UI packages are being brought to the same coverage over time. |
| **Cross-workspace analytics** | Resource attribution is live. Higher-level dashboards and billing views are expanding. |

## What is live in Release 4

Recent platform changes customers can rely on now.
Each is a result, not a promise of future work.

| Change | Result |
|---|---|
| Disk corruption guard | Restoring a memory snapshot onto a disk that grew after the snapshot is refused instead of corrupting the filesystem. Live on the control plane and all hosts. |
| Guest isolation from the internal network | A sandbox cannot reach the platform's own network except the managed-database proxy range. The Firecracker rule ordering that stops an older allow rule from shadowing the deny is live fleet-wide, and SOMA already enforced it. |
| Preview fallback for white-label staff | Preview access for a white-label organization's own staff falls back to the authenticated console path instead of failing. |
| Disk larger than the pre-built slot | A request for a disk larger than the pre-built slot boots at the requested size instead of failing or returning the wrong size. |
| Learn credits cooldown | An expired Learn attempt is timed from its expiry, and an expired attempt with no answers no longer counts as a failure. |
| Function pool | The per-host function pool is deployed but dark: it is not a customer surface yet. |
| SOMA catalog accuracy | The runtime catalog no longer advertises pause or snapshots for SOMA, which has neither. |

## Planned

| Capability | Notes |
|---|---|
| Native GPU sandboxes | Targeted early 2027, for workloads that need accelerated inference or rendering. |
| Edge functions | Targeted Q1 2027, as a deployment target separate from origin runtimes. |
| Native nameservers | Targeted Q4 2026, for customers who want MIOSA to manage more of the domain lifecycle. |
| OTLP export | Planned for teams that want platform traces in their own observability stack. |
| Test-mode API keys | Planned to separate production billing from integration testing. |

## Deliberate product boundaries

MIOSA is focused on AI-generated software, isolated execution, live previews, desktop automation, white-label SaaS infrastructure, and durable deployment. It is deliberately not:

- **Managed Kubernetes**. Sandboxes and Deployments cover the workloads people would otherwise use K8s for.
- **Generic VPS hosting**. Compute is always tied to a tenant identity (workspace or `external_workspace_id`).
- **Cryptocurrency or blockchain primitives**.

# Browser use

URL: https://miosa.ai/docs/browser-use
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/browser-use
Source: src/routes/docs/browser-use/+page.md
Description: A live browser inside any MIOSA sandbox - watch it, take control, share a view-only link, and let agents drive the same browser over CDP.

# Browser use

**Browser use** gives a sandbox a real, interactive browser.
It is available on **every sandbox**, on any template, with nothing to choose at create time: the browser is part of the sandbox, not a separate machine. The live viewer is the one exception on SOMA today, noted below.

Inside the sandbox the browser runs on a virtual display (`Xvfb :99`), so it needs no desktop session.
That display ships in the sandbox image.
One exception today: a SOMA sandbox ships Docker and Chromium but not the virtual display the live viewer renders, so the live viewer is not available on SOMA yet.

A person can watch it, take control, or share a view-only link.
An agent connects to the **same** browser over CDP, so automation and a human share one session, one set of cookies, and one page.

Browser use is a single browser inside a sandbox and bills as ordinary sandbox usage.
If a task needs a full desktop, other apps, or takeover of the whole screen, use [Computer use](/docs/computer-use/) instead.
See [Which to pick](/docs/computer-use/vs-browser-use/).

## 1. Create a sandbox

Any sandbox works, on any template.

```bash
miosa create my-box --wait
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
})
console.log(sandbox.id, sandbox.state)
```

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sandbox = miosa.sandboxes.create(template_id="miosa-sandbox")
print(sandbox.id, sandbox.state)
```

Wait until the sandbox `state` is `running`.

## 2. Start the browser

The browser starts lazily on the first `POST`.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

The response carries `state`, `viewport`, `stream_url`, `cdp_url`, and a short-lived `stream_auth` token.
See [Quickstart](/docs/browser-use/quickstart/) for every field.

## 3. Open it or drive it

A person opens the viewer, or an agent connects over CDP.

```bash
# The viewer is a WebSocket on api.miosa.ai, authenticated with the stream token.
wss://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser/stream?token=$STREAM_AUTH
```

Take control or share a view-only link in the [Live viewer](/docs/browser-use/live-viewer/).

```javascript

const cdpUrl = `${browser.cdp_url}?token=${browser.stream_auth}`

const browserConn = await chromium.connectOverCDP(cdpUrl)
const context = browserConn.contexts()[0]
const page = context.pages()[0] ?? (await context.newPage())

await page.goto("https://example.com")
console.log(await page.title())

await browserConn.close()   // detaches; it does not stop the sandbox browser
```

```python
from playwright.sync_api import sync_playwright

cdp_url = f"{browser['cdp_url']}?token={browser['stream_auth']}"

with sync_playwright() as p:
    browser_conn = p.chromium.connect_over_cdp(cdp_url)
    context = browser_conn.contexts[0]
    page = context.pages[0] if context.pages else context.new_page()

    page.goto("https://example.com")
    print(page.title())

    browser_conn.close()   # detaches; it does not stop the sandbox browser
```

Stopping the browser with `DELETE /browser` frees its memory while the sandbox keeps running.
The browser survives **pause and resume**.

# Drive a sandbox browser over CDP

URL: https://miosa.ai/docs/browser-use/cdp
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/browser-use/cdp
Source: src/routes/docs/browser-use/cdp/+page.md
Description: Connect Playwright and Puppeteer to a live sandbox browser over CDP and drive the same session a viewer is watching.

# Drive it over CDP

The sandbox browser speaks the Chrome DevTools Protocol.
Point Playwright or Puppeteer at the browser's CDP endpoint and your agent drives the **same** browser the live viewer shows - same tabs, same logins, same page.

The CDP endpoint is a WebSocket on `api.miosa.ai`:

```
wss://api.miosa.ai/api/v1/sandboxes/{id}/browser/cdp
```

It is control only. A view-only share token is refused here.

## Get the endpoint

`POST /browser` starts the browser and returns `cdp_url` and `stream_auth`:

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

## Authenticate the CDP socket

The socket takes the same credentials as the stream:

- `?token=<stream_auth>` - the token returned by `POST` (1 hour). Simplest for an agent.
- `Authorization: Bearer <msk_* API key>` - API keys need the `sandboxes:exec` scope; a browser can reach anything the sandbox can, so the scope is deliberate.

## Playwright

The browser is already running with a page. Use the existing context and page instead of launching a new browser, so you act on the session the viewer sees.

```python
from playwright.sync_api import sync_playwright

cdp_url = f"{browser['cdp_url']}?token={browser['stream_auth']}"

with sync_playwright() as p:
    browser_conn = p.chromium.connect_over_cdp(cdp_url)
    context = browser_conn.contexts[0]
    page = context.pages[0] if context.pages else context.new_page()

    page.goto("https://example.com")
    print(page.title())

    browser_conn.close()   # detaches; it does not stop the sandbox browser
```

```javascript

const cdpUrl = `${browser.cdp_url}?token=${browser.stream_auth}`

const browserConn = await chromium.connectOverCDP(cdpUrl)
const context = browserConn.contexts()[0]
const page = context.pages()[0] ?? (await context.newPage())

await page.goto("https://example.com")
console.log(await page.title())

await browserConn.close()   // detaches; it does not stop the sandbox browser
```

You can pass the token as a header instead of a query parameter when your client supports it, for example Playwright's `connect_over_cdp(cdp_url, headers={"Authorization": "Bearer " + api_key})`.

## Puppeteer

```javascript

const browser = await puppeteer.connect({
  browserWSEndpoint: `${browserInfo.cdp_url}?token=${browserInfo.stream_auth}`,
})

const [page] = await browser.pages()
await page.goto("https://example.com")
console.log(await page.title())

await browser.disconnect()   // detaches; it does not stop the sandbox browser
```

`browser.close()` in Playwright and `browser.disconnect()` in Puppeteer detach the agent.
They do not stop the sandbox browser, so a viewer stays connected.
To stop the browser and free its memory, `DELETE /browser` - see [Limits](/docs/browser-use/limits/).

## One browser, two drivers

Because the viewer and the agent share one browser:

- A person can open the live viewer while an agent is running and watch the agent work.
- If a person takes control, the agent's next action lands on the same page.
- Cookies and logins persist across both, and across pause and resume of the sandbox.

Keep the agent and the human from acting at the same instant by taking control only when the automation is idle.

## Close codes

If the socket closes before it is ready, the close code says why:

| Code | Meaning |
|---|---|
| `4001` | Unauthorized |
| `4003` | Forbidden (the key lacks `sandboxes:exec`) |
| `4004` | Sandbox not found |
| `4009` | Sandbox not running |
| `4012` | Browser not started - call `POST /browser` first |
| `4013` | Tenant stream limit reached |
| `4014` | Share link expired or revoked |
| `1011` | Upstream failure |

# How browser use works

URL: https://miosa.ai/docs/browser-use/how-it-works
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/browser-use/how-it-works
Source: src/routes/docs/browser-use/how-it-works/+page.md
Description: The parts of a sandbox browser, the three surfaces that see it, and how the live view and CDP sockets are exposed.

# How browser use works

## What you get


    Start it in any running sandbox and watch the page render in real time on the Sandbox page.


    A viewer can take control and use the browser directly, or share a revocable view-only link.


    Playwright and Puppeteer connect over CDP and drive the same browser the viewer is watching.


    It runs inside the sandbox you already have, so it bills as plain sandbox usage.


## How it fits together

- **Start.** Ask the sandbox to start its browser. It starts lazily on the first request, stays up across pause and resume, and stops when you stop it.
- **Watch and drive.** The Sandbox page shows the live browser. A viewer can take control; a view-only link can watch but never drive.
- **Automate.** Playwright or Puppeteer connect to the live browser over CDP and act on the same session a person sees.

Because the viewer and the automation share one browser, a person can open the page mid-run, watch, and take control without losing cookies, logins, or page state.

## The three viewers of one browser

| Surface | Who | What they can do |
|---|---|---|
| Live viewer on the Sandbox page | The signed-in owner | Watch the browser, take control |
| View-only share link | Anyone with the link | Watch only; cannot drive the browser |
| CDP endpoint | An agent (Playwright, Puppeteer) | Drive the browser over the Chrome DevTools Protocol |

A view-only share link cannot type, click, or navigate. Input is rejected inside the browser process in the sandbox, not just hidden in the UI.

Both sockets - the live-view stream and the CDP endpoint - are on `api.miosa.ai`, with normal API authentication.
Nothing is exposed on the sandbox's own host or on a template port.

Source: src/routes/docs/browser-use/integrations/+page.md
Description: Connect a Chrome DevTools Protocol client to a MIOSA sandbox browser. Only clients verified end to end are listed.

# Integrations

Any client that speaks the Chrome DevTools Protocol can drive a sandbox browser.
Only clients verified end to end on MIOSA are listed here; more will be added as they are proven.

## Compatibility

Each client below was run against a live sandbox browser: connect, navigate, click, type, screenshot, and confirm a live viewer sees the same page.

| Client | Language | Version | Status |
|---|---|---|---|
| Playwright | JavaScript | 1.64.0 | **Tested** |
| Playwright | Python | 1.63.0 | **Tested** |
| Puppeteer | JavaScript | 25.13.0 | **Tested** |
| Raw CDP | Node (no library) | Node 24 | **Tested** |
| Stagehand | JavaScript | 3.7.3 | **Tested** |
| browser-use | Python | 0.13.11 | **Tested** |
| Computer use (screenshot + actions) | Any HTTP client | - | **Tested** |

## Connect

Every CDP client connects to the same endpoint on `api.miosa.ai`:

```
wss://api.miosa.ai/api/v1/sandboxes/{id}/browser/cdp
```

`POST /browser` starts the browser and returns `cdp_url` and `stream_auth`.
Authenticate the socket one of two ways:

- **Token in the URL.** Append the `stream_auth` token as `?token=`:

  ```
  wss://api.miosa.ai/api/v1/sandboxes/{id}/browser/cdp?token=<stream_auth>
  ```

- **Authorization header.** `Authorization: Bearer <msk_* API key>` (the key needs the `sandboxes:exec` scope), for clients that can set headers on the WebSocket.

Both go through `api.miosa.ai`; nothing is exposed on the sandbox's own host.
The endpoint is control only: a view-only share token is refused here.

`POST /browser` also returns `cdp_ws_url` and `cdp_http_url`, which carry the token in the path for clients that cannot set headers or append a query string.
`cdp_http_url` answers `/json/version`, `/json/list`, `/json/new`, and `/json/protocol`, and rewrites every advertised `webSocketDebuggerUrl` to itself, so clients that follow discovery stay authenticated.

The browser is already running with a page. Use the existing context and page instead of launching a new browser, so you act on the session the live viewer shows.

## Client examples

```javascript

const cdpUrl = `${browser.cdp_url}?token=${browser.stream_auth}`

const browserConn = await chromium.connectOverCDP(cdpUrl)
const context = browserConn.contexts()[0]
const page = context.pages()[0] ?? (await context.newPage())

await page.goto("https://example.com")
console.log(await page.title())
await page.screenshot({ path: "page.png" })

await browserConn.close()   // detaches; it does not stop the sandbox browser
```

Or authenticate with a header, avoiding the token in the URL:

```javascript
const browserConn = await chromium.connectOverCDP(browser.cdp_url, {
  headers: { Authorization: `Bearer ${process.env.MIOSA_API_KEY}` },
})
```

```python
from playwright.sync_api import sync_playwright

cdp_url = f"{browser['cdp_url']}?token={browser['stream_auth']}"

with sync_playwright() as p:
    browser_conn = p.chromium.connect_over_cdp(cdp_url)
    context = browser_conn.contexts[0]
    page = context.pages[0] if context.pages else context.new_page()

    page.goto("https://example.com")
    print(page.title())
    page.screenshot(path="page.png")

    browser_conn.close()   # detaches; it does not stop the sandbox browser
```

```javascript

const browser = await puppeteer.connect({
  browserWSEndpoint: `${browserInfo.cdp_url}?token=${browserInfo.stream_auth}`,
})

const [page] = await browser.pages()
await page.goto("https://example.com")
console.log(await page.title())

await browser.disconnect()   // detaches; it does not stop the sandbox browser
```

Puppeteer can also discover the socket for you: pass `browserURL: cdp_http_url`, and Puppeteer reads `/json/version` and follows the rewritten `webSocketDebuggerUrl`.

```javascript
// Plain WebSocket, no client library.
const url = `${browser.cdp_url}?token=${browser.stream_auth}`

const ws = new WebSocket(url)
const pending = new Map()
let nextId = 1

ws.addEventListener("message", (event) => {
  const message = JSON.parse(event.data)
  pending.get(message.id)?.(message)
  pending.delete(message.id)
})

const send = (method, params = {}) =>
  new Promise((resolve) => {
    const id = nextId++
    pending.set(id, resolve)
    ws.send(JSON.stringify({ id, method, params }))
  })

await new Promise((resolve) => ws.addEventListener("open", resolve))
console.log((await send("Browser.getVersion")).result.product)

// Page-level work: discover a page target through /json/list,
// then open a second socket to its page-level URL.
const list = await (await fetch(`${browser.cdp_http_url}/json/list`)).json()
console.log(list[0].webSocketDebuggerUrl)
```

```javascript

const stagehand = new Stagehand({
  env: "LOCAL",
  localBrowserLaunchOptions: {
    cdpUrl: `${browser.cdp_url}?token=${browser.stream_auth}`,
  },
})

await stagehand.init()
const page = (await stagehand.context.pages())[0]
await page.goto("https://example.com")
console.log(await page.title())
```

```python

from browser_use import Browser

async def main():
    # `browser` is the POST /browser response: { "cdp_url": ..., "stream_auth": ... }
    cdp_url = f"{browser['cdp_url']}?token={browser['stream_auth']}"

    agent = Browser(cdp_url=cdp_url, is_local=True)
    await agent.start()
    page = await agent.get_current_page()
    await page.goto("https://example.com")
    print(await page.get_title())
    # browser-use evaluates with the function form:
    print(await page.evaluate("(...a) => document.title"))
    await agent.stop()

asyncio.run(main())
```

```javascript
// OpenAI/Anthropic computer-use style loop: screenshots plus coordinate actions.
// No CDP in the client at all.
const base = `https://api.miosa.ai/api/v1/sandboxes/${sandboxId}/browser`
const headers = { Authorization: `Bearer ${apiKey}` }

// A screenshot of the current page
const shot = await fetch(`${base}/screenshot?format=png`, { headers })

// Navigate, type, and click by coordinate
await fetch(`${base}/actions`, {
  method: "POST",
  headers: { ...headers, "content-type": "application/json" },
  body: JSON.stringify({
    actions: [
      { type: "navigate", url: "https://example.com" },
      { type: "wait", ms: 600 },
      { type: "type", text: "miosa" },
      { type: "click", x: 140, y: 270 },
    ],
  }),
})
```

Action types are `click`, `double_click`, `triple_click`, `move`, `drag`, `scroll`, `type`, `key` (for example `"ctrl+a"` or `"Enter"`), `navigate`, `back`, `forward`, `reload`, and `wait`.
`GET /browser/screenshot` takes `format=png|jpeg`, `encoding=base64`, and `tab=ID`.

## Stagehand 4.x

Stagehand 4.x is not supported: it requires pipe-only CDP.
Use Stagehand 3.x.

`browser.close()` in Playwright and `browser.disconnect()` in Puppeteer detach your driver. They do not stop the sandbox browser, so a viewer stays connected.
To stop the browser and free its memory, `DELETE /browser` - see [Limits](/docs/browser-use/limits/).

# Browser use limits, billing, and security

URL: https://miosa.ai/docs/browser-use/limits
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/browser-use/limits
Source: src/routes/docs/browser-use/limits/+page.md
Description: Availability and size, lifecycle across pause and resume, how browser use is billed, and how access is enforced.

# Limits, billing, and security

## Availability

Browser use is available on every running sandbox, on any template.
One exception today: a SOMA sandbox ships Docker and Chromium but not the virtual display the live viewer renders, so the live viewer is not available on SOMA yet.
The browser starts lazily on the first `POST /browser`, so sandboxes that never use it pay nothing and boot as fast as before.

The sandbox image must include a Chromium-family browser and Node.
Every MIOSA sandbox image ships them; a custom image that removed them returns `501 BROWSER_NOT_AVAILABLE`.

No template publish is needed to use the browser: the daemon ships with the control plane and is written into the sandbox on start, on every launchable template.

## Size

A real Chromium needs room. `small` (2 vCPU, 4 GB) or larger is recommended for a comfortable browser.

| Size | vCPU | RAM | Browser use |
|---|---|---|---|
| `xs` | 1 | 2 GB | Tight; a single light page at most |
| `small` | 2 | 4 GB | **Recommended minimum** |
| `medium` | 4 | 8 GB | Comfortable |
| `large` | 8 | 16 GB | Heavy pages and parallel tabs |

## Lifecycle

| Action | Effect on the browser |
|---|---|
| `POST /browser` | Starts the browser lazily (idempotent) |
| Pause sandbox | Browser state is preserved; the session survives resume |
| Resume sandbox | The same browser comes back, with its tabs and logins |
| `DELETE /browser` | Stops the browser and frees its memory; the sandbox keeps running |
| Destroy sandbox | Removes everything, including browser state |

Pause and resume keep the browser; stopping the browser is what releases its memory.

## Saved website sign-ins

The platform stores a person's saved website sign-ins so the sandbox browser can fill them without the agent ever seeing the password.
`GET /api/v1/signins` lists them, `PUT /api/v1/signins/{site}` saves one, and `DELETE /api/v1/signins/{site}` removes one.
Send `workspace_id`; a request without it answers `422 WORKSPACE_REQUIRED`.
Responses are masked: they carry a username preview and `last_used_at`, never the password.
`POST /api/v1/sandboxes/{id}/browser/signin` with `{"site": "..."}` fills the saved sign-in into the open tab, only on your own running sandbox and only on an HTTPS page of that site.

The browser is also a process inside the sandbox, so if the sandbox is restarted the browser must be started again. `GET /browser` reports the current state (`running`, `stopped`, `unavailable`, or `sandbox_not_running`) without starting anything.

## Billing

Browser use bills as **plain sandbox usage**.
There is no separate browser line item: while the sandbox is running, you pay the sandbox rate you already pay for that size, and the browser runs inside it.
Stopping the browser frees memory but does not by itself stop the sandbox.

## Security

- Nothing is exposed publicly. Both sockets - the live-view stream and the CDP endpoint - go through `api.miosa.ai` with normal API authentication, never through the sandbox's own host.
- The control plane connects to the browser daemon on the sandbox's loopback only, and hands it a 60-second token each time. Callers never see that token.
- An **API key on a socket needs `sandboxes:exec`**, because a browser can reach anything the sandbox can.
- Share tokens are **view-only**. Their input is refused inside the sandbox's browser process, not merely hidden in the UI.
- Share links are **revocable**: revoke one link by its `share_id`, or revoke every share and CDP link at once. Revoking bumps the browser's share epoch, so an outstanding link stops working immediately.
- Live-view and CDP sockets share a per-tenant stream limit; exceeding it closes the socket with `4013`.

Mint viewer and CDP access on your backend.
Send only the short-lived `stream_auth` token or a share link to the browser or the agent.
Never ship a MIOSA API key to the frontend.

# Browser use live viewer

URL: https://miosa.ai/docs/browser-use/live-viewer
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/browser-use/live-viewer
Source: src/routes/docs/browser-use/live-viewer/+page.md
Description: Watch a sandbox browser live, take control, share a revocable view-only link, and go full screen.

# Live viewer

The live viewer renders the sandbox browser in a page you can watch.
It needs the sandbox's virtual display (`Xvfb :99`), which ships in the sandbox image, and which a SOMA sandbox does not have yet.
It lives on the Sandbox page in the MIOSA console, and the same protocol serves any client you build.

The viewer is a WebSocket at `wss://api.miosa.ai/api/v1/sandboxes/{id}/browser/stream`: JPEG frames and JSON events come down, JSON input goes up.
It goes through `api.miosa.ai`, never the sandbox's own host.

## Three ways to open it

| Surface | How | Capability |
|---|---|---|
| Sandbox page | Open the sandbox, then its browser panel | Take control |
| Stream URL | `stream_url` from the browser API, with `stream_auth` | Take control |
| View-only share link | Minted for someone else | Watch only |

## Authenticate the stream

Two ways, both on `api.miosa.ai`:

- `Authorization: Bearer <msk_* API key | session JWT>`, or
- `?token=<stream_auth>` for clients that cannot set headers (the `stream_auth` value from `POST`).

API keys used here need the `sandboxes:exec` scope.
A viewer that only watches can pass `?mode=view`, which reaches the view-only listener in the sandbox.

## Take control

A viewer opened on the Sandbox page, or with a control-mode stream, can take control: click, type, scroll, and navigate the live page.
Input goes straight to the browser process, so the page the agent is driving is the page you are steering.

## Share a view-only link

Mint a share link to let someone watch without touching the browser.
No MIOSA login is required to use it.

```bash
curl -X POST "https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser/share?ttl_seconds=600" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

```json
{
  "data": {
    "mode": "view",
    "share_token": "bs1.1783000000.0.9f3c...",
    "expires_at": "2026-10-10T13:00:00Z",
    "stream_url": "wss://api.miosa.ai/api/v1/sandboxes/sbx_01j9x/browser/stream"
  }
}
```

| Field | Meaning |
|---|---|
| `mode` | Always `view`. |
| `share_token` | The view-only token; pass it as `?share=<share_token>` on `stream_url`. |
| `expires_at` | When the link stops working. |
| `stream_url` | The stream WebSocket the link connects to. |

`ttl_seconds` is optional: it defaults to `3600` and must be between `60` and `604800` (7 days).
Out of range is `400 INVALID_TTL`.

The share link opens the same stream as a view-only viewer:

```
wss://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser/stream?share=$SHARE_TOKEN
```

A view-only link is **revocable**: revoking it stops every outstanding link for that browser immediately.

```bash
curl -X DELETE https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser/share \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

```json
{ "data": { "revoked": true, "epoch": 1 } }
```

Revocation bumps the sandbox's share `epoch`; every token minted at an earlier epoch is rejected from then on.

View-only is enforced inside the sandbox's browser process, not in the page. A view-only viewer receives frames; its input is refused on the machine, so it can never type, click, or navigate - whatever mode it asks for.

## Full screen

The viewer has a full-screen control that expands the browser to the whole screen for closer inspection or a kiosk-style display.
Toggle it off to return to the embedded frame.

- [Limits, billing, security](/docs/browser-use/limits/) - what the viewer can and cannot do.

# Browser use quickstart

URL: https://miosa.ai/docs/browser-use/quickstart
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/browser-use/quickstart
Source: src/routes/docs/browser-use/quickstart/+page.md
Description: Start a live browser in any MIOSA sandbox, read its stream and CDP endpoints, and stop it when you are done.

# Quickstart

Browser use runs inside a sandbox, on every template, with no extra setup.
You create a sandbox as usual, then start its browser.

The browser starts lazily on the first `POST`. Sandboxes that never use a browser pay nothing, and sandbox boot stays as fast as it is today.

## 1. Start a sandbox

Any sandbox works, on any template. Nothing about the browser is chosen at create time.
The live viewer needs the sandbox's virtual display, which a SOMA sandbox does not have yet.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "template_id": "miosa-sandbox", "size": "small" }'
```

Wait until the sandbox `state` is `running`.

## 2. Start the browser

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

The response carries everything you need:

```json
{
  "data": {
    "state": "running",
    "epoch": 0,
    "viewport": { "width": 1280, "height": 720 },
    "stream_url": "wss://api.miosa.ai/api/v1/sandboxes/sbx_01j9x/browser/stream",
    "cdp_url": "wss://api.miosa.ai/api/v1/sandboxes/sbx_01j9x/browser/cdp",
    "stream_auth": "miosa_stream_...",
    "stream_auth_expires_at": 1783000000
  }
}
```

| Field | Meaning |
|---|---|
| `state` | `running` when the browser is up. |
| `epoch` | Share-link epoch. Bumping it revokes every outstanding share link. |
| `viewport` | Browser viewport, `1280` by `720`. |
| `stream_url` | WebSocket for the live view (`wss://api.miosa.ai/...`). |
| `cdp_url` | WebSocket Chrome DevTools Protocol endpoint for agents. |
| `stream_auth` | A short-lived token for the viewer or CDP socket. |
| `stream_auth_expires_at` | Unix seconds when `stream_auth` expires (1 hour). |

`POST` is idempotent: calling it again on a running browser returns the same endpoints without restarting it.

`GET` needs the `sandboxes:read` scope.
`POST` and `DELETE` need `sandboxes:write`.
The WebSocket endpoints need `sandboxes:exec` when you authenticate with an API key.

## 3. Open the viewer

In the MIOSA console, open the sandbox and use its browser panel.
To open the viewer yourself, connect to `stream_url` and authenticate.

```bash
# The viewer protocol is a WebSocket: JPEG frames and JSON events down, JSON input up.
# Pass the token as a query parameter...
wss://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser/stream?token=$STREAM_AUTH
# ...or as a header: Authorization: Bearer $STREAM_AUTH
```

From there a viewer can **take control** of the browser or share a **view-only link**.
See [Live viewer](/docs/browser-use/live-viewer/).

## 4. Let an agent drive it

The browser a person is watching is the same browser an agent connects to over CDP.
Connect to `cdp_url` with Playwright or Puppeteer - see [Drive it over CDP](/docs/browser-use/cdp/).

## 5. Check the state without starting it

`GET` only reports state; it never starts the browser.

```bash
curl https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

```json
{
  "data": { "state": "running", "epoch": 0, "viewport": { "width": 1280, "height": 720 } }
}
```

For a sandbox that is not running, `state` is `sandbox_not_running` and no guest is touched:

```json
{ "data": { "state": "sandbox_not_running", "epoch": 0 } }
```

## 6. Stop the browser

```bash
curl -X DELETE https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

```json
{
  "data": { "state": "stopped", "epoch": 0, "viewport": { "width": 1280, "height": 720 } }
}
```

Stopping the browser frees its memory while the sandbox keeps running.
The browser survives **pause and resume** of the sandbox; stopping it is what releases the memory.

## Errors

| Status | Code | Cause |
|---|---|---|
| `400` | `INVALID_ID` | The sandbox id is not a UUID |
| `404` | `NOT_FOUND` | Unknown sandbox, or one owned by another tenant |
| `401`/`403` | - | Missing or insufficient credentials |
| `409` | `SANDBOX_NOT_RUNNING` | The sandbox must be running to start or stop the browser |
| `501` | `BROWSER_NOT_AVAILABLE` | The sandbox image has no Chromium or Node |
| `502` | `BROWSER_START_FAILED` | The browser daemon did not come up in time |

`501` names a template that ships the browser prerequisites: the sandbox image includes Chromium and Node.

# Build an app like...

URL: https://miosa.ai/docs/build
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/build
Source: src/routes/docs/build/+page.md
Description: Guides for platform builders. Run open-source agents and frameworks on MIOSA, or build familiar AI products like Lovable, Manus and Perplexity - app builders, coding agents, autonomous and computer-use agents, chat and companions, answer engines, multi-agent, voice, design, video, vertical apps, and an internal Business OS.

Every guide is one of two kinds:

- **Run X on MIOSA.** Open-source agents, frameworks and tools you can actually install and use (OpenClaw, Hermes Agent, OpenHands, Claude Code, Codex, Cursor's CLI agent, CrewAI, AutoGen, LangGraph, Pipecat, Browser Use, Stagehand, Steel). The guide and its agent prompt install the real tool from its official docs, run it on a MIOSA sandbox or computer, and then wrap it for your team or your customers.
- **Build an app like X.** Closed products you cannot run yourself (Lovable, Bolt, v0, Manus, Perplexity, Character.AI and others). The guide names the product, maps each of its capabilities onto a MIOSA primitive, and builds your own version.

Either kind can be set up **two ways, on the same architecture**:

- **For your own company (internal).** One organization, a workspace per team, access control and SSO, and an internal domain. No billing.
- **As a product (for your customers).** Multi-tenant: white-label branding, an organization or workspace per customer, custom domains, and usage metering.

Each guide ships an **agent prompt tailored to what you are building** - pick the shape and a name, and hand the brief to OSA, Claude Code, Codex, or Cursor. Browse the apps and platforms below.

MIOSA is the execution layer underneath AI products. The core idea runs through every guide:
**build your product powered by Claude Code, Codex, Hermes, OpenClaw, OSA, or your own model**.
The harness runs inside a MIOSA sandbox or computer, and your product wraps it.

There are two paths, and they are not exclusive:


    Background coding agents, parallel sessions per sandbox, and a persistent workspace per developer. No product to build: just run Claude Code, Codex, Cursor, or your own harness in the cloud and watch the work.


    Wrap a harness in your own UI, model, and billing: a Lovable-style builder, an internal workspace, or a customer-facing product, using Claude Code, Hermes, OpenClaw, or your own model under the hood.


## Ideas to build


    A branded desktop/web app where your users chat with an agent that works in its own cloud computer, with a browser and files.


    The agent builds something (a site, a doc, a dashboard, or an app), shares it at a preview URL, then promotes it to a deployment on your own branded domain.


    An Acme Corp-style internal platform: one place for your team's agents, apps, and data, behind your own login.


    The same shape, Lumen-style and white-label: your brand, your domains, and your end users, with MIOSA running behind them.


    Put Claude Code, Codex, or Cursor agents in sandboxes: background work, parallel sessions, and a persistent workspace each.


    An orchestrator that fans work out to child agents in their own machines and joins the results.


Each guide has the same shape: a **prompt builder**, **What you're building**, a
**What you need on MIOSA** checklist with a create command per resource, an **architecture
diagram**, six numbered steps (**create an account and API key → create the resources → wire
the agent loop → preview → deploy → custom domain**), **costs and limits**, and **next steps**.

# Run Browser Use on MIOSA

~15 min TypeScript Python

> **What you're building**: Install the open-source library and let an agent drive a real browser.
>
> **Primitives you'll use**: Computer, Sandbox

This guide runs **Browser Use** on MIOSA. You don't have to use it.
You can build your own browser agent instead, on MIOSA alone: drive the [live browser inside a sandbox](/docs/browser-use) over CDP, or a full [computer](/docs/computer-use) with screenshots, clicks and typing.
You own the loop, the prompts, the model and the product.
See [Build a browser and computer-use agent](/docs/build/chatgpt-agent).

# Build an internal Business OS

sequenceDiagram
  participant T as Your team
  participant B as BusinessOS (Go + SvelteKit)
  participant S as MIOSA Sandbox
  participant D as MIOSA Deploy

  T->>S: clone Miosa-osa/BusinessOS and run make onboard
  S->>B: start Go backend, SvelteKit frontend, Postgres and Redis
  B-->>T: the internal OS on a preview URL
  T->>B: work in modules, then customize them in the clone
  T->>D: publish the web frontend
  D-->>T: https os.example.net

## Customizing it

BusinessOS is a template, not a fixed product: the meaning of a module comes from your company, not from the repo. A fresh install shows an intentional unshaped-module screen until you give it shape. Everything you edit lives in the clone you already have:

- **Frontend and modules** live in `frontend/` (SvelteKit). A module is a route plus the people, agents, records, states, and policies it owns; start from an existing foundational route as a template.
- **Go backend** lives in `desktop/`: the API your modules call for their data.
- **Knowledge and agents** come from the bundled Optimal Engine in `optimal-engine/`, which gives the assistant memory, search, and agent context over your own data.
- **Workspace shape** lives in `workspaces/`: teams, roles, and the private projections a workspace starts from.

Change code in the running machine and restart the stack to see it:

```bash
miosa exec business-os-box --cwd /workspace/BusinessOS -- make dev-local-restart
```

The repository's own [docs/](https://github.com/Miosa-osa/BusinessOS/tree/main/docs) cover the architecture, module authoring, and operations in depth.

# CLI overview

URL: https://miosa.ai/docs/cli
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli
Source: src/routes/docs/cli/+page.md
Description: The miosa command line tool. Install, sign in, and drive sandboxes, computers, agents, deployments and every platform resource from the terminal.

`miosa` covers the whole platform: sandboxes and computers, files and previews, agents and their runs, deployments, databases, storage, API keys, webhooks, billing and the organization you work in.

## Quick start

```bash
npm i -g @miosa/cli               # or Homebrew, the install script, or a release archive
miosa --version                   # prints 2.3.1
miosa login                       # browser device-code sign in
miosa whoami                      # user, organization, plan and scopes
miosa create my-box --wait        # provision a sandbox
miosa exec my-box -- echo hello   # run a command
miosa destroy my-box --yes
```







## Use the CLI from agents

The CLI is not only for humans. [OSA](/docs/mcp#osa), MIOSA's open-source agent, runs shell commands, so it can drive `miosa` from your machine or from a MIOSA computer. `osa run "..."` runs it headless with no TUI. Any agent with shell access can do the same, and drive the entire platform with `miosa`: it covers every resource the API and the SDKs expose, not just a tool surface, and it composes with the shell and the tools the agent already has.

- **Install inside a sandbox or CI.** `npm i -g @miosa/cli` is the fastest path in a container or CI job. Sandbox images ship Node, so a fresh agent machine has the CLI in one command.
- **Authenticate with a key.** Set `MIOSA_API_KEY` and every command is authenticated with no browser. Never pass a key as an argument.
- **Get JSON and exit codes.** Add `--json` for machine-readable output and branch on the exit code. `exec` and `ssh` exit with the remote command's status.

```bash
export MIOSA_API_KEY="msk_u_..."
npm i -g @miosa/cli

# An agent provisioning, using and cleaning up a machine, all scriptable
ID=$(miosa create agent-box --size small --ttl 1h --wait --json | jq -r .id)
miosa exec "$ID" -- npm ci
miosa preview create "$ID" 3000 --visibility public --json | jq -r .url
miosa destroy "$ID" --yes
```

An agent running in Claude Code or Codex with shell access uses exactly these commands: provision a sandbox, run a build, publish a preview, read the JSON, clean up. No MCP setup required.

### When the CLI beats MCP

Use the **CLI** when the agent already has a shell. It reaches the whole platform rather than one tool surface, its output is scriptable and composes with `jq`, pipes and files, and `miosa api  <path>` covers any endpoint the high-level commands do not. Use **MCP** when the client has no shell, or when you want the model to choose tools rather than write commands. See [CLI or MCP: which to use](/docs/cli/cli-vs-mcp).

## Command groups

Every top-level command, grouped the way the CLI organises them.

| Group | Commands |
|---|---|
| Account | `login`, `logout`, `whoami`, `org`, `limits`, `profile`, `config`, `doctor`, `open`, `update`, `version` |
| Lifecycle | `create`, `list`, `info`, `use`, `destroy`, `stop`, `pause`, `resume`, `fork`, `recover`, `extend`, `tag`, `wait`, `usage`, `computer`, `device` |
| Work inside | `exec`, `ssh`, `console`, `files`, `process` (`ps`), `services`, `logs`, `events`, `ports`, `preview`, `url`, `proxy`, `desktop` |
| State | `snapshot`, `checkpoint`, `restore`, `env`, `policy` |
| Sandbox resources | `sandbox` (`resources`, `resize`) |
| Agents | `prompt`, `run`, `chat`, `agent`, `connections`, `mcp` |
| Platform | `deploy`, `batch`, `host`, `db`, `storage`, `volume`, `workflow`, `schedule`, `function`, `template`, `project`, `workspace`, `forge`, `catalog`, `regions`, `egress`, `cloud`, `gateway` |
| Access and billing | `api-key`, `service-account`, `webhook`, `member`, `billing`, `audit`, `alerts`, `notifications` |
| Raw | `api  <path>` with `-d` (`@file` or `-`) and `-H` |

## Machine arguments

Anywhere a sandbox is expected you may give its name, its id, `current` (set with `miosa use`) or `self` (inside a sandbox). Commands that act on a computer take `--computer`.

```bash
miosa exec my-box -- npm test      # by name
miosa exec sbox_abc123 -- npm test # by id
miosa use my-box                   # then omit the name
miosa exec -- npm test
```

## Global flags

These apply to every command.

```text
--api-key string      API key (overrides MIOSA_API_KEY and config)
--api-url string      API base URL (overrides MIOSA_BASE_URL and config)
--profile string      Config profile to use (MIOSA_PROFILE)
--org string          Organization to bill for this command (MIOSA_ORG)
--json                Machine-readable JSON (same as -o json)
-o, --output string   text (default) or json (MIOSA_OUTPUT)
-q, --quiet           Suppress informational output
--retries int         Retries on 429 and transient 5xx (default 3, MIOSA_RETRIES)
--timeout int         Request timeout in seconds; for exec and ssh the command timeout
--no-update-notice    Silence the new-version notice
```

## Exit codes

| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | Error |
| 2 | Usage |
| 3 | Not signed in, or forbidden |
| 4 | Not found |
| 5 | Conflict or invalid input |
| 6 | Rate limited (after retries) |
| 7 | Server or network error |

`miosa exec` and `miosa ssh` exit with the remote command's status.

# Access, org and billing

URL: https://miosa.ai/docs/cli/access-billing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/access-billing
Source: src/routes/docs/cli/access-billing/+page.md
Description: API keys, service accounts, webhooks, members, billing, audit log, alerts and notifications from the miosa CLI.

## API keys

```bash
miosa api-key create my-key --preset cli
miosa api-key list
miosa api-key presets
miosa api-key rotate <key>
miosa api-key update <key> --name renamed --rate-limit 600
miosa api-key rm <key> --yes
```

`api-key create` takes `--preset` (`read-only`, `ci`, `agent` or `cli`), `--scope` (repeatable, for example `sandboxes:exec`), `--expires-in` (days), `--rate-limit`, `--allowed-ip` (repeatable), `--workspace-id` and `--quiet-key` (print only the secret).

Scoped keys for external users:

```bash
miosa api-key scoped --external-user-id <id> --workspace-id <id> --scope sandboxes:exec --expires-at 2027-01-01T00:00:00Z
```

## Service accounts

Non-human accounts that own API keys for pipelines and programs.

```bash
miosa service-account new deploy-pipeline
miosa service-account list
miosa service-account key new <account> --preset ci --expires-in 90 --quiet-key
miosa service-account keys <account>
miosa service-account update <account> --description "..." --name renamed
miosa service-account rm <account> --yes
```

`service-account key new` takes the same scoping flags as `api-key create`.

## Webhooks

Send events to your own HTTPS endpoints.

```bash
miosa webhook create https://example.com/hook --name deploys --event sandbox.created
miosa webhook list
miosa webhook get <webhook>
miosa webhook events
miosa webhook deliveries <webhook>
miosa webhook test <webhook>
miosa webhook replay <webhook> <delivery>
miosa webhook update <webhook> --active --event sandbox.created --retries 5
miosa webhook rm <webhook> --yes
```

`webhook create` takes `--event` (repeatable, see `webhook events`), `--header NAME=VALUE` (repeatable), `--retries` (0 to 10) and `--workspace-id`.

## Members

```bash
miosa member list
miosa member add <email> --role member
miosa member role <member> --role admin
miosa member rm <member> --yes
```

Roles are `admin`, `member` or `viewer`.

## Billing

```bash
miosa billing plan
miosa billing balance
miosa billing spend
miosa billing usage
miosa billing breakdown
miosa billing invoices
miosa billing upcoming
miosa billing transactions -n 50 --page 1
```

`miosa billing usage` shows model usage by day and takes no filters. To filter the product catalog by `--product`, `--size`, `--state` or `--template`, use `miosa catalog`.

## Audit log

```bash
miosa audit -n 50 --type sandbox.created --workspace-id <id>
```

## Alerts and notifications

```bash
miosa alerts list
miosa alerts resolve <alert>

miosa notifications list
miosa notifications unread
miosa notifications read <notification>
miosa notifications read-all
```

Billing reads the organization new machines bill. Pin it with `miosa org bill <org>`, or override per command with `--org`. See [Account and environment](/docs/cli/account).

| `miosa org members` | Members of the organization |
| `miosa org invite <email> --role member` | Invite a person (`owner`, `admin` or `member`) |
| `miosa org caps` | Show member caps |

`--org` on any command overrides the pinned organization for that command:

```bash
miosa --org acme list
miosa --org acme create build-box
```

Member caps limit what one person can spend or run:

```bash
miosa org caps set dana --spend 25            # dollars per billing period
miosa org caps set dana --concurrent 10       # most machines at once
miosa org caps set dana --no-spend-cap
miosa org caps set dana --no-concurrency-cap
```

## Limits

```bash
miosa limits
```

Shows the limits of the organization a new machine would bill.

## Open the console

```bash
miosa open            # open the web console in a browser
miosa open --print    # print the URL instead
```

## Version and updates

```bash
miosa version
miosa update          # download and replace the binary
miosa update --check  # report only
```

## Doctor

```bash
miosa doctor
```

Checks configuration, connectivity and authentication, and prints a fix for each failure.

Members and their roles live under `miosa member` for day to day changes, and under the organization for invites and caps. API keys and service accounts live under their own pages: [Access, org and billing](/docs/cli/access-billing).

# Agents, chats and runs

URL: https://miosa.ai/docs/cli/agents
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/agents
Source: src/routes/docs/cli/agents/+page.md
Description: Run agents on a sandbox or computer, manage saved agent definitions, chats and durable runs, and see how runs stream.

## Bring your own model

Agent runs use your own model-provider connections, never MIOSA platform keys. Mint a key that can do this with `miosa api-key create NAME --preset cli`. Add a connection with `miosa connections add models` (the key is read from a prompt or stdin, never from an argument). A run without a usable connection fails with a message that names this command.

```bash
miosa api-key create agent-key --preset cli
miosa connections add models
```

## Prompt

Run an agent on a sandbox or computer and follow it.

```bash
miosa prompt --sandbox my-box "fix the failing test"
miosa prompt --new-machine --harness codex "write a README"
miosa prompt --sandbox my-box --continue
```

| Flag | Meaning |
|---|---|
| `-s, --sandbox string` | Sandbox to run in (default: the current sandbox) |
| `--computer string` | Computer to run in |
| `--agent string` | Run a saved agent (name or id) instead of an ad hoc one |
| `--harness string` | `claude-code`, `codex` or `osa` (default: the agent's, or `claude-code`) |
| `--model string` | Model for the harness (default: the harness default) |
| `--new-machine` | Provision a machine for this run |
| `--machine string` | Kind of new machine: `sandbox` or `computer` |
| `--size string` | Size of a new machine |
| `--template string` | Template of a new machine |
| `--chat string` | Chat id; continues the chat if it has runs |
| `--new-chat` | Start a chat (a new chat id is printed) |
| `--reuse string` | New machine lifetime: `run` (one per run) or `chat` (one per `--chat`, files persist) |
| `--after-run string` | What happens to a new machine when the run ends: `destroy`, `pause` or `keep` |
| `--max-time int` | Stop the run after this many seconds |
| `--no-follow` | Print the run id and return without waiting |
| `--notify-email` | Email you when the run finishes |
| `--notify-webhook string` | Webhook id to notify when the run finishes |

## Saved agents

An agent is a saved, versioned definition: harness, model, instructions, the machine it runs on, and what it may do. `<agent>` is a name or an id.

```bash
miosa agent new reviewer --harness claude-code --instructions-file review.md
miosa agent publish reviewer --file config.yaml
miosa agent list
miosa agent diff reviewer 2 3
miosa agent run reviewer "review PR 42" --sandbox my-box
miosa agent harnesses
```

`miosa agent new` takes `--harness` (`claude-code`, `codex`, `osa` or `custom`), `--model`, `--instructions` or `--instructions-file`, `--overdrive` (run the harness without approval prompts), `--timeout-sec`, `--description`, and a full `--file` (YAML or JSON).

Other subcommands: `agent get`, `agent versions`, `agent version`, `agent update`, `agent duplicate`, `agent rm`, `agent runs`, `agent templates`, `agent triggers`, `agent approvals`, `agent authority`, `agent defaults`, `agent harness-versions`.

## Runs

List, follow and stop agent runs.

```bash
miosa run list --status running
miosa run get <id>
miosa run follow <id>
miosa run events <id>
miosa run logs <id>
miosa run messages <id>
miosa run outputs <id>
miosa run files <id>
miosa run diagnostics <id>
miosa run download <id> -O out.tar
miosa run steer --sandbox my-box "also add tests"   # queue the next turn for the running agent
miosa run interrupt --sandbox my-box                # stop the agent attached to a machine
miosa run stop <id>
miosa run usage --group-by model
```

`miosa run list` filters with `--agent-id`, `--chat`, `--harness`, `--source`, `--status`, `--target`, `--workspace-id` and `--limit`.

## Chats

Chats are agent conversations that remember.

```bash
miosa chat list
miosa chat start --sandbox my-box --harness claude-code
miosa chat show <chat-id>
miosa chat context <chat-id>     # how full the context is
miosa chat compact <chat-id>     # compact it so the chat can go on
```

## Connections

Model providers, apps and tool servers your agents use.

```bash
miosa connections add models
miosa connections list --kind models
miosa connections test <name>
miosa connections share <name>
miosa connections rm <name>
```

`miosa connections add` takes `--key-stdin` (never a key on the command line), `--label`, `--workspace-id`, `--url` (for an MCP tool server) and `--header-env HEADER=ENV_VAR` (repeatable).

Runs are the canonical agent execution contract. `miosa prompt`, `miosa agent run` and `miosa chat` all create runs; `miosa run` reads and controls them.

# Raw API access

URL: https://miosa.ai/docs/cli/api
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/api
Source: src/routes/docs/cli/api/+page.md
Description: Call any MIOSA API endpoint from the CLI with your stored credentials, using miosa api.

`miosa api` sends a request to the MIOSA API with your stored credentials and prints the response body. The path is relative to the API base URL (`/api/v1`). Use it for anything the CLI has no command for yet.

```bash
miosa api [METHOD] <path> [flags]
```

The method defaults to GET, or POST when `--data` is given.

```bash
miosa api /credits/balance
miosa api GET /sandboxes/my-box/ports
miosa api POST /webhooks -d '{"url":"https://example.com/hook","events":["sandbox.ready"]}'
miosa api PATCH /sandboxes/my-box/tags -d @tags.json
echo '{"name":"x"}' | miosa api POST /workspaces -d -
```

| Flag | Meaning |
|---|---|
| `-X, --method string` | HTTP method (default GET, or POST with `--data`) |
| `-d, --data string` | Request body: JSON, `@file`, or `-` for stdin |
| `-H, --header stringArray` | Extra header, `'Name: value'` (repeatable) |
| `-i, --include` | Print the status line and response headers first |

A failing status exits non-zero (see exit codes) and still prints the body.

## When to reach for the raw API

| Need | Use |
|---|---|
| Code/build/test/runtime workspace | `miosa create`, `miosa exec`, `miosa files`, `miosa services`, `miosa url` |
| Full GUI/browser computer | `miosa api /computers ...` or an SDK (`client.computers`) |
| Docker Host appliance | SDK or API Docker Host endpoints; publish from a sandbox to Docker Host |
| Product/template readiness | `miosa catalog` |
| Anything else | `miosa api  <path>` |

`miosa api` uses the same profile, key and organization as every other command. Combine it with `--json` and `jq` for scripting. See [JSON output and scripting](/docs/cli/scripting).

# CLI or MCP: which to use

URL: https://miosa.ai/docs/cli/cli-vs-mcp
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/cli-vs-mcp
Source: src/routes/docs/cli/cli-vs-mcp/+page.md
Description: The miosa CLI is for humans and scripts in a terminal; MCP gives AI clients the same capabilities as tools. Both use the same API key and scopes.

- The **CLI** (`miosa`) is for humans, scripts and agents with a shell. You type commands, read text or JSON, and branch on exit codes.
- **MCP** gives AI clients (Claude Code, Codex, Cursor, Claude Desktop) the same capabilities as tools. The model calls tools by name instead of running shell commands.

Both use the **same API key and the same scopes**. A key that can create a sandbox from the CLI can create one over MCP, and the reverse. The only difference is the surface.

## Which should an agent use?

- **Has a shell? Use the CLI.** Claude Code, Codex, Cursor's terminal and any CI job can run `miosa`. The CLI is often the better choice: it reaches the whole platform, not just one tool surface; output is scriptable; and it composes with `jq`, pipes and files.
- **No shell? Use MCP.** Claude Desktop chat and other hosted chat products have no shell, so tools are the only path. MCP lets the model call capabilities by name.

Nothing is lost either way, because the key, the scopes and the resources are identical.

## Comparison

| | CLI | MCP |
|---|---|---|
| Who drives it | A person, a script, or an agent with a shell | An AI client without a shell (Claude Desktop), or one that prefers tools |
| Interface | `miosa <command> [flags]` | JSON-RPC tools over Streamable HTTP or stdio |
| Install | npm, Homebrew, install script, Releases | Hosted endpoint, no install, or `pip install miosa-mcp` |
| Output | Text or JSON, with exit codes | Structured tool results and images |
| Coverage | The whole platform, plus `miosa api` for any endpoint | The MCP tool surface |
| Best for | Agents with shell access, build loops, CI, one-off operations | Clients without a shell |
| Auth | `msk_u_*` key or a profile | `msk_u_*` key as a Bearer token |
| Scope model | Same key scopes | Same key scopes |

## Use both

A common split: an agent with a shell drives the platform with the CLI, and a client without a shell reaches the same account over MCP with the same key.

```bash
ID=$(miosa create agent-box --size small --wait --json | jq -r .id)   # CLI, from a shell agent
miosa exec "$ID" -- npm test
# the same account over MCP: exec(sandbox_id=ID, command="npm run build")
miosa list --json | jq -r '.data[].name'                              # CLI, read back
```




Both surfaces inherit the same tenant scoping, plan limits, credit checks and audit logging, because both sit in front of the MIOSA REST API.

# Config and profiles

URL: https://miosa.ai/docs/cli/config
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/config
Source: src/routes/docs/cli/config/+page.md
Description: Named sign-ins and defaults in ~/.miosa/config.toml, plus the config commands, options and environment variables.

Settings live in `~/.miosa/config.toml` (mode 0600). The API key is never printed by `config`; sign in with `miosa login`.

## Config commands

```bash
miosa config list            # effective settings of the current profile (alias ls)
miosa config get <key>       # print one setting
miosa config set <key> <value>
miosa config path            # print the config file path
```

Keys: `api_url`, `current_sandbox`, `default_workspace`.

```toml
api_url           = "https://api.miosa.ai/api/v1"
api_key           = "msk_u_..."
default_workspace = "default"
current_sandbox   = "my-box"
```

## Profiles

A profile is a named sign-in with its own API URL, organization and defaults. Several profiles let you keep accounts or environments apart.

```bash
miosa login --profile work
miosa profile list
miosa profile use work
miosa --profile default list
```

| Command | What it does |
|---|---|
| `miosa profile add <name>` | Create an empty profile (then `miosa login --profile <name>`) |
| `miosa profile list` | List profiles (alias `ls`) |
| `miosa profile show [name]` | Show a profile's settings (the key is masked) |
| `miosa profile use <name>` | Make a profile the default for new commands |
| `miosa profile rm <name>` | Delete a profile and its stored key |

`miosa profile add` takes `--api-url` and `--workspace`.

### Which profile is in effect

1. `--profile`
2. `MIOSA_PROFILE`
3. the one set with `miosa profile use`
4. `default`

## Credential resolution

1. `--api-key`
2. `MIOSA_API_KEY`
3. the active profile in `~/.miosa/config.toml`

## Environment variables

```text
MIOSA_API_KEY          API key
MIOSA_BASE_URL         API base URL
MIOSA_PROFILE          Profile to use
MIOSA_ORG              Organization to bill
MIOSA_OUTPUT           Output format (text or json)
MIOSA_RETRIES          Retries on 429 and transient 5xx
MIOSA_NO_UPDATE_NOTICE Set to 1 to silence the new-version notice
```

## Sign out

```bash
miosa logout                # remove the stored key of the active profile
miosa logout --all          # delete the config file (all profiles)
```

`miosa doctor` checks configuration, connectivity and authentication, and prints a fix for each failure.

# Devices

URL: https://miosa.ai/docs/cli/devices
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/devices
Source: src/routes/docs/cli/devices/+page.md
Description: miosa device is one surface over every runtime kind you can run work on - sandboxes, computers and more - for listing, exec, files, ports and lifecycle.

A device is any runtime MIOSA can run a command on: a sandbox, a computer or another kind. `miosa device` is one surface over all of them, so a script does not need to know which kind it is talking to. `<device>` is an id.

```bash
miosa device list
miosa device list --status running
miosa device capabilities <device>
miosa device exec <device> -- uname -a
```

Aliases: `devices`.

## Commands

| Command | What it does |
|---|---|
| `miosa device list` | List devices (`-n, --limit`, `--name`, `--status`) |
| `miosa device get <device>` | Show one device (alias `show`) |
| `miosa device capabilities <device>` | What this device can do (alias `caps`) |
| `miosa device exec <device>` | Run a command (`-c, --command`, `--timeout-ms`) |
| `miosa device files <device>` | List a directory (`--path`, default `/workspace`; alias `ls`) |
| `miosa device read <device>` | Read a file, base64 (`--path`) |
| `miosa device write <device>` | Write a file (`--path`, `--content`, or `--file`) |
| `miosa device expose <device> <port>` | Publish a port |
| `miosa device browser <device>` | Show a device's browser URL (computers) |
| `miosa device extend <device>` | Replace the time to live (`--timeout`, for example `30m` or `2h`) |
| `miosa device pause <device>` / `resume <device>` | Pause or resume |
| `miosa device stop <device>` | Stop, keeping the disk |
| `miosa device rm <device> --yes` | Destroy permanently (aliases `delete`, `destroy`) |

## exec

```bash
miosa device exec <device> -- uname -a
miosa device exec <device> -c "npm test" --timeout-ms 120000
```

`miosa device exec` exits with the remote command's status, like `miosa exec`.

## Files

```bash
miosa device files <device> --path /workspace
miosa device read <device> --path /workspace/out.json
miosa device write <device> --path /workspace/app.py --content "print(1)"
```

`miosa device read` returns the file contents base64-encoded. `miosa device write` takes the contents from `--content`, or a JSON body with `--file`.

## When to use device or the typed command

Use `miosa device` when a script should work across runtime kinds, or when you have an id and do not know what it is. Use `miosa exec`, `miosa files` or `miosa computer` when you know the kind and want the fuller, kind-specific surface.

Machines are also addressable by name in the typed commands (`miosa exec my-box -- ...`). `miosa device` takes an id. See [Machines and lifecycle](/docs/cli/machines).

# Environments

URL: https://miosa.ai/docs/cli/environments
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/environments
Source: src/routes/docs/cli/environments/+page.md
Description: The template a new sandbox or computer starts from: repositories, variables, secret files and credentials, with immutable versions.

An environment is the template a new sandbox or computer starts from. It decides which repositories are cloned, which variables and secret files are injected, and which of your credentials the machine may use. Every workspace has one default environment named `base`. A machine without `--env` uses the default of its workspace.

## Commands

```bash
miosa env list
miosa env new staging
miosa env info staging
miosa env rename staging stage
miosa env rm staging
miosa env default
```

Commands that edit one environment take `--env <name>`, and edit the default environment when it is omitted. `--workspace <slug>` scopes any `miosa env` command to one workspace. Without it the API uses the workspace of a workspace-bound key, and the organization level otherwise.

## Variables and secret files

```bash
miosa env set --env staging STRIPE_KEY       # value is asked for, input hidden
miosa env set --env staging --from-file .env
miosa env unset --env staging STRIPE_KEY
miosa env file put --env staging hello-world/backend/.env ./backend.env
miosa env info staging                        # masked
miosa env info staging --reveal               # print values; written to the audit log
```

A value is never accepted as an argument, because arguments end up in shell history. Give the `NAME` and enter the value when asked, pipe it on stdin, or load a `.env` file with `--from-file`.

`miosa env info` masks variable values and never prints secret file contents. `--reveal` prints variable values and writes each reveal to the audit log.

## Repositories

```bash
miosa env repo add --env staging octocat/hello-world --branch develop --setup-file ./repo-setup.sh --blocking
```

`--source` selects `github` or `forge` (default `github`). `--blocking` means the machine is not usable until the setup script finishes; `--non-blocking` runs it alongside everything else.

## Toggles and protection

```bash
miosa env toggle --env staging github off
miosa env protect --env staging on
```

The four toggles are `github`, `secrets`, `machine-key` and `agent-connections`. `protect on` passes nothing of yours, whatever the toggles say. `miosa create --no-env` gives the same guarantee to one sandbox. `miosa env new --safe-for-third-parties` gives it to the environment itself.

## Versions and upgrades

```bash
miosa env versions staging     # how many machines sit on each version
miosa info my-box              # shows "staging v1", and whether an upgrade is available
miosa env upgrade my-box       # move one machine to the latest version
miosa env upgrade --all staging
```

Every save that changes what a machine receives creates a new immutable version. A machine pins the latest version when it starts and keeps it. Saving never reaches into a running machine.

An upgrade is not reversible on the machine's disk. A secret the new version withholds is deleted from the machine, so `miosa env upgrade` asks you to confirm unless you pass `--force`.

## Start a machine from an environment

```bash
miosa create my-box --env staging
miosa computer create --env staging --size small
```

## Setup scripts

`--setup-file ./setup.sh` runs a script (UTF-8, at most 64KB) once, in the background, after the machine is ready. It never delays `ready`. Watch it with `miosa info`: the setup status is `pending`, `running`, `done` or `failed`, and a failed run shows its error. The CLI checks the size and encoding before it sends anything.

```bash
miosa create my-box --env staging --setup-file ./setup.sh
miosa info my-box
miosa env repo add --env staging octocat/hello-world --setup-file ./repo-setup.sh --blocking
```

# Install and authenticate

URL: https://miosa.ai/docs/cli/install
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/install
Source: src/routes/docs/cli/install/+page.md
Description: Install the miosa CLI from npm, Homebrew, the install script or a release archive on macOS, Linux and Windows, verify 2.3, then sign in.

`miosa` is the official MIOSA command line tool. There is one `miosa` CLI: version 2.3. It runs on macOS, Linux and Windows.

## 1. Install

```bash
curl -fsSL https://raw.githubusercontent.com/Miosa-osa/miosa-cli-go/main/install.sh | sh
```

macOS and Linux. Installs to `~/.local/bin/miosa` for non-root users and `/usr/local/bin/miosa` for root. Override with `INSTALL_DIR=/usr/local/bin`.

```bash
npm i -g @miosa/cli
```

Installs the `miosa` 2.3 CLI. The package resolves the right native build for your platform, including Windows x64. Works the same on macOS, Linux and Windows.

The installer does these steps:

1. Detects your OS and CPU.
2. Downloads the matching `miosa` binary and checks its SHA-256.
3. Installs the binary onto your `$PATH`.

Then sign in with `miosa login` (step 3 below): it opens your browser, and the key for this machine is stored in `~/.miosa/config.toml`.

Prefer another install path?

```bash
brew install --cask Miosa-osa/homebrew-tap/miosa
```

macOS only.

Download the archive for your platform from [GitHub Releases](https://github.com/Miosa-osa/miosa-cli-go/releases/latest) and place the binary in a directory on your `$PATH`.

```text
miosa_2.3.1_darwin_arm64.tar.gz
miosa_2.3.1_darwin_amd64.tar.gz
miosa_2.3.1_linux_arm64.tar.gz
miosa_2.3.1_linux_amd64.tar.gz
miosa_2.3.1_windows_amd64.zip
```

## 2. Verify

```bash
miosa --version
miosa version
```

These print `2.3.1`. If they print `1.x`, run `npm i -g @miosa/cli@latest` or `brew upgrade` to move onto the 2.x line.

## Windows

The npm install is the simplest path on Windows: `npm i -g @miosa/cli` resolves the `win32-x64` build (`@miosa/cli-win32-x64`) and puts `miosa` on your PATH.

To install by hand, download `miosa_2.3.1_windows_amd64.zip` from [GitHub Releases](https://github.com/Miosa-osa/miosa-cli-go/releases/latest), extract `miosa.exe`, and add its folder to your `PATH`. In PowerShell:

```powershell
$dir = "$env:USERPROFILE\miosa"
Expand-Archive -Path "$env:USERPROFILE\Downloads\miosa_2.3.1_windows_amd64.zip" -DestinationPath $dir
[Environment]::SetEnvironmentVariable("Path", "$env:Path;$dir", "User")

# open a new terminal, then
miosa --version
```

`SetEnvironmentVariable` with the `User` scope makes the change permanent without admin rights; it only affects terminals opened after you run it. For the current session only, use `$env:Path += ";$dir"` instead.

Windows builds are x64 only. There is no windows/arm64 archive.

## Upgrading from 1.x

1.x was the Node CLI. 2.x is the same `miosa` command with a rewritten command surface, and the installs above now all give you 2.3.x.

What changed:

- **Sandbox commands lost the `sandbox` prefix.** `miosa sandbox create` is now `miosa create`.
- **Deployment work moved under `miosa deploy`.** The old `miosa app` and top-level `releases`, `rollback` and `builds` commands are now `miosa deploy` subcommands. New in 2.2: `miosa deploy create` publishes a sandbox, a git repository or a local directory.
- **Contexts became profiles.** `miosa context` is now `miosa profile`, stored in `~/.miosa/config.toml`.
- **Restored in 2.1.** Several 1.x command families came back, renamed: `miosa device` (any runtime kind), `miosa mcp`, and the `miosa host` families for containers, meshes, GitHub Actions runners, backups and tunnels.
- **Still removed from the public CLI:** the internal OSA tooling `actions`, `blueprint`, `changes`, `drift`, `evidence`, `capabilities` and `command-overview`. Action authority is server-side, and `miosa --help` replaces `command-overview`.

Renamed commands:

| `miosa actions ...` | removed (authority is server-side) |

## Update

```bash
miosa update            # download and replace the binary
miosa update --check    # report only
miosa version
```

`miosa update` verifies the SHA-256 of the download against the release `checksums.txt`, and refuses to replace a Homebrew-managed binary (use `brew upgrade` there). A one-line notice appears at most once a day when a newer version exists; silence it with `--no-update-notice` or `MIOSA_NO_UPDATE_NOTICE=1`.

## Shell completion

```bash
miosa completion zsh      # bash, fish, powershell
```

Sandbox names, profiles, templates and agents complete from the live API.

## 3. Sign in

```bash
miosa login               # opens the browser, device-code sign in
miosa whoami              # organization, plan, credits, and the scopes your key holds
```

`miosa whoami` shows the user, organization, workspace, plan and the scopes the key holds.

### Sign in with a key

`miosa login --with-key` asks for a key with hidden input, and `--key-stdin` reads it from stdin. A key is never accepted as an argument.

```bash
miosa login --with-key
echo "$MIOSA_KEY" | miosa login --key-stdin
```

### Credential resolution

Credentials resolve in this order:

1. `--api-key`
2. `MIOSA_API_KEY`
3. the active profile in `~/.miosa/config.toml`

CI and other non-interactive environments use `MIOSA_API_KEY`. See [Config and profiles](/docs/cli/config) for multi-account setups.

## Sign out

```bash
miosa logout
```

Removes the stored key of the active profile. `miosa logout --all` deletes the config file for every profile.

## Diagnose

```bash
miosa doctor
```

Checks configuration, connectivity and authentication, and prints a fix for each failure.

# Machines and lifecycle

URL: https://miosa.ai/docs/cli/machines
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/machines
Source: src/routes/docs/cli/machines/+page.md
Description: Create, list, inspect, stop, fork, recover and destroy sandboxes and computers with the miosa CLI.

A machine is either a sandbox (code and headless work) or a computer (a full GUI desktop). Lifecycle commands work on both.

## Create a sandbox

```bash
miosa create [name] [flags]
```

```bash
miosa create my-box --wait
miosa create ci-box --size small --template miosa-sandbox --ttl 2h --wait
miosa create my-box --env staging --setup-file ./setup.sh
```

| Flag | Meaning |
|---|---|
| `--size string` | `micro`, `tiny`, `xs`, `small`, `quad`, `medium`, `large`, `xl` (default `small`) |
| `--template string` | Template staged inside the sandbox image, for example `nextjs` or `static-html` (default `miosa-sandbox`) |
| `--env string` | Environment the sandbox starts from (default: your default environment) |
| `--no-env` | Pass nothing of yours to the sandbox (safe to hand to third parties) |
| `--setup-file string` | Shell script (UTF-8, max 64KB) run in the background once the sandbox is ready |
| `--ttl string` | Time to live: seconds, `90m`, `2h` or `2d` (default: the plan's) |
| `--idle-timeout string` | Pause after this much inactivity: seconds, `15m`, `1h` |
| `--meta stringArray` | Metadata, `KEY=VALUE` (repeatable) |
| `--workspace string` | Workspace slug to assign the sandbox to |
| `--wait` | Wait until the sandbox is ready for commands |
| `--wait-timeout duration` | How long `--wait` may take (default `3m0s`) |

## List and inspect

```bash
miosa list --state running
miosa list --json | jq -r '.data[].name'
miosa info my-box            # state, environment and setup status
miosa usage my-box           # runtime, time left and estimated cost
```

`miosa list` takes `--state`, `--tag`, `--template`, `--search`, `--workspace`, `--workspace-id`, `--limit`, `--page`, `--ids` (print only ids) and `--errored` (include sandboxes in the error state).

`miosa info` shows the pinned environment version (for example `staging v1`) and whether an upgrade is available.

## Current sandbox

```bash
miosa use my-box     # set the current sandbox
miosa use            # show it
miosa exec -- npm test
```

Anywhere a sandbox is expected you may give its name, its id, `current` or `self` (inside a sandbox).

## Start, stop, pause, resume, restart

```bash
miosa stop my-box     # keep the disk
miosa pause my-box    # keep disk and memory state
miosa resume my-box
miosa restart my-box --wait   # power-cycle in place: same id, same disk
```

`miosa restart` stops the sandbox keeping its disk and boots that disk again, so files, packages and enabled services survive and running processes start fresh.
Use it when a sandbox stops answering.
If its host stopped it with a memory checkpoint instead, the sandbox comes back from memory and the command says so, with the next step.

## Extend, tag and wait

```bash
miosa extend my-box --for 2h    # replace the time to live
miosa tag my-box --set team=ci
miosa wait my-box --for running
```

`miosa extend --for` accepts seconds, `90m`, `2h` or `2d`, and replaces the old value rather than adding to it.

## Fork and recover

```bash
miosa fork my-box copy-box      # a running copy of a sandbox
miosa recover my-box            # recover the disk into a NEW sandbox
```

## Destroy

```bash
miosa destroy my-box --yes
miosa destroy my-box other-box
```

`--yes` is required when there is no terminal. Destroy is permanent.

## Computers

Computers are the GUI machines. Every command that acts on one takes `--computer` where a machine argument appears.

| Command | What it does |
|---|---|
| `miosa computer create --size small` | Create a computer (`--size`, `--template`, `--env`, `--setup-file`) |
| `miosa computer list` | List computers |
| `miosa computer get <id>` | Details and status |
| `miosa computer start` / `stop` / `restart` | Power states |
| `miosa computer logs` | Recent VM-level logs |
| `miosa computer ports` / `urls` | Exposed ports and public URLs |
| `miosa computer auto-stop` | Auto-stop settings |
| `miosa computer rm --yes` | Destroy permanently |

To drive the desktop (screenshot, click, type), use an SDK or the MCP tools. The CLI exposes computer lifecycle, logs, ports and URLs. See [sdks overview](/docs/sdks).

# Platform resources

URL: https://miosa.ai/docs/cli/platform
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/platform
Source: src/routes/docs/cli/platform/+page.md
Description: Deployments, databases, storage, volumes, workflows, schedules, functions, templates, hosts, forge, cloud, egress and the AI gateway from the miosa CLI.

## Deployments

```bash
miosa deploy create --from-sandbox <sandbox> --wait
miosa deploy create --git <url> --branch main --wait
miosa deploy create --dir ./dist --name my-site
miosa deploy                          # deploy the current directory
miosa deploy list
miosa deploy get <deployment>
miosa deploy logs <deployment> -n 200
miosa deploy env <deployment>          # environment variable names
miosa deploy env-set <deployment> --set KEY=VALUE
miosa deploy redeploy <deployment>
miosa deploy rollback <deployment> --to <version-id>
miosa deploy versions <deployment>
miosa deploy releases <deployment>
miosa deploy observe <deployment>
miosa deploy builds <deployment>       # build logs
miosa deploy requests <deployment>
miosa deploy promote <deployment>
miosa deploy stop <deployment> --yes
miosa deploy rm <deployment> --yes
miosa deploy domains <deployment>
miosa deploy domain-add <deployment> <domain>
miosa deploy domain-verify <deployment> <domain>
miosa deploy domain-rm <deployment> <domain>
```

`miosa deploy rollback --to` returns to a named version; without it, the previous one.

`miosa deploy env` lists the deployment's environment variable names. `miosa deploy env-set <deployment> --set KEY=VALUE` sets them, and values are encrypted at rest. `--set` is repeatable.

```bash
miosa deploy env my-app
miosa deploy env-set my-app --set DATABASE_URL=postgres://... --set LOG_LEVEL=info
```

### Create a deployment

`miosa deploy create` (alias `miosa deploy publish`) publishes a new deployment and makes it live. Give it one source:

- `--from-sandbox <sandbox>` publishes a running sandbox's output. Add `--port <n>` and `--run-command` to publish a running server, `--entrypoint <file>` to pick the entry file of a static publish, or `--type docker_deploy` for Docker Host.
- `--git <url>` connects a repository and queues its first build. Add `--branch` and `--build-command`.
- `--dir <path>` packages a local directory and uploads it, for pre-built static output with no repository.

With `--from-sandbox`, `--dir` is the path the app lives at inside the sandbox (default `/workspace`). On its own, `--dir` is a local directory to upload.

```bash
miosa deploy create --from-sandbox my-box --wait
miosa deploy create --from-sandbox my-box --port 3000 --run-command "npm start"
miosa deploy create --git https://github.com/me/app --branch main --wait
miosa deploy create --dir ./dist --name my-site
```

Common flags: `--name`, `--env KEY=VALUE` (repeatable, encrypted at rest), `--domain`, and `--wait` to block until the deployment is live and print its public URL. `--json` prints the result as JSON.

`miosa deploy` with no subcommand deploys the current directory: the git repository when the directory is one, otherwise a directory upload. It asks before publishing unless you pass `--yes`.

## Databases

```bash
miosa db list
miosa db get <db>
miosa db connection <db>        # connection string
miosa db logs <db>
miosa db backups <db>
miosa db backup <db>
miosa db restart <db>
miosa db start <db>
miosa db stop <db> --yes
miosa db wake <db>
miosa db rm <db> --yes
```

## Storage

Object storage buckets.

```bash
miosa storage list
miosa storage create assets --visibility private --region <region>
miosa storage get assets
miosa storage objects assets --prefix uploads/ -n 50
miosa storage rm assets --yes
```

## Volumes

Persistent volumes shared between machines.

```bash
miosa volume list
miosa volume create data --size-gb 20
miosa volume get <volume>
miosa volume rm <volume> --yes
```

## Functions

Edge functions.

```bash
miosa function list
miosa function get <function>
miosa function invoke <function> -d '{"key":"value"}'
miosa function rm <function> --yes
```

## Workflows

Automations made of steps, agents and tools.

```bash
miosa workflow list
miosa workflow get <workflow>
miosa workflow run <workflow> --input '{"branch":"main"}'
miosa workflow runs <workflow>
miosa workflow run-get <workflow> <run>
miosa workflow run-cancel <workflow> <run>
miosa workflow pause <workflow> / resume <workflow>
miosa workflow rm <workflow> --yes
```

## Schedules

Scheduled jobs.

```bash
miosa schedule list
miosa schedule get <schedule>
miosa schedule executions <schedule>
miosa schedule run <schedule>
miosa schedule pause <schedule> / resume <schedule>
miosa schedule rm <schedule> --yes
```

## Templates

```bash
miosa template list
miosa template get <template>
miosa template build <template>
miosa template builds <template>
miosa template build-logs <template> <build>
miosa template custom <template>
miosa template promote <template>
miosa template rollback <template> --yes
miosa template warm-pool
miosa template rm <template> --yes
```

## Batch

Create many sandboxes in one request.

```bash
miosa batch new --count 50 --size small --name-prefix ci --wait
miosa batch status <batch>
miosa batch items <batch> --limit 20
miosa batch watch <batch> --timeout 15m
miosa batch cancel <batch>
```

`batch new` takes `--count`, `--size`, `--template`, `--name-prefix`, `--region`, `--ttl`, `--idle-timeout`, `--tag KEY=VALUE`, `--concurrency`, `--workspace`, `--wait` and `--wait-timeout`.

## Projects and workspaces

```bash
miosa project list
miosa project create <name> --description "..." --workspace-id <id>
miosa project get <project>

miosa workspace list
miosa workspace create <slug>
miosa workspace get <slug>
miosa workspace members <slug>
miosa workspace stats <slug>
miosa workspace usage <slug>
miosa workspace inventory <slug>
miosa workspace activity <slug>
miosa workspace use <slug>
miosa workspace delete <slug>
```

## Catalog and regions

```bash
miosa catalog --product sandbox --template nextjs
miosa catalog --state fast_ready
miosa catalog --output json | jq '.data[] | select(.state == "fast_ready")'
miosa regions
```

`miosa catalog` is the canonical catalog for products, templates, sizes and readiness.

## Forge (beta)

```bash
miosa forge repo list
miosa forge repo create platform --visibility private
miosa forge pr new platform --head fix-redirect --title "Fix redirect loop"
miosa forge pr review platform 12 --decision approved
miosa forge pr merge platform 12
miosa forge check report platform --commit <sha> --name unit-tests --conclusion passed --file evidence.json
miosa forge release new platform --tag v1.2.0
miosa forge policy set platform --branch main --approvals 2 --check unit-tests
```

Forge repository commands always return a `{ "data": ... }` success envelope. Repository mutations accept `--idempotency-key`, and delete requires interactive confirmation or `--yes`. Forge clone is not exposed until MIOSA provides a credential-helper flow that keeps credentials out of URLs, arguments, shell history, logs and persistent Git configuration.

## Egress

Outbound network policy for sandboxes.

```bash
miosa egress policies
miosa egress allowlist --policy <id>
miosa egress suggestions
miosa egress audit -n 50
```

## Your own hosts

```bash
miosa host register studio --platform macos    # prints the host key once
miosa host list --tag studio
miosa host get <host>
miosa host metrics <host>
miosa host runtime <host>
miosa host services <host>
miosa host jobs <host>
miosa host ssh-key
miosa host secret
miosa host tag <host>
miosa host app catalog
miosa host cluster ...
miosa host group ...
miosa host fs ...
miosa host rm <host> --yes
```

`miosa host register --platform` takes `macos`, `linux` or `windows`.

### Containers

Containers on a host.

```bash
miosa host container list <host>
miosa host container run <host> --image nginx:alpine --name web --set PORT=8080
miosa host container get <host> <container>
miosa host container logs <host> <container>
miosa host container stats <host> <container>
miosa host container start <host> <container>
miosa host container stop <host> <container>
miosa host container restart <host> <container>
miosa host container rm <host> <container> --force --yes
```

`miosa host container logs` and `miosa host container stats` stream until the connection ends or Ctrl-C is pressed. With `--json` each event is one JSON object per line. `miosa host container run` takes `--image`, `--name`, `--cmd` (repeatable), `--set KEY=VALUE` (repeatable) and `--restart`.

### Meshes

Private encrypted host-to-host networks over WireGuard.

```bash
miosa host mesh list
miosa host mesh new lab --host <host> --host <host>
miosa host mesh get lab
miosa host mesh add-host lab <host>
miosa host mesh remove-host lab <host> --yes
miosa host mesh events lab
miosa host mesh rm lab --yes
```

`miosa host mesh events` streams host joins, key rotation and state changes until Ctrl-C.

### GitHub Actions runners

Self-hosted GitHub Actions runners on a host, registered for one repository.

```bash
miosa host gha-runner list <host>
miosa host gha-runner new <host> --repo https://github.com/acme/app --token <token>
miosa host gha-runner new <host> --repo https://github.com/acme/app --token-secret GH_TOKEN --ephemeral
miosa host gha-runner get <host> <runner>
miosa host gha-runner events <host> <runner>
miosa host gha-runner refresh <host> <runner>
miosa host gha-runner rm <host> <runner> --yes
```

`miosa host gha-runner new` takes `--repo`, `--token` (sent to the host, not stored) or `--token-secret` (the name of a host secret holding the token), `--name`, `--label` (repeatable) and `--ephemeral` (deregister after one job). `miosa host gha-runner events` streams as the runner picks up and finishes jobs.

### Backups and snapshots

Scheduled backups of directories on a host. A configuration names a directory, a schedule and how many snapshots to keep. Snapshots can be forked onto a host.

```bash
miosa host backup list <host>
miosa host backup new <host> --name nightly --path /data --schedule "0 3 * * *" --keep 7
miosa host backup update <host> nightly --schedule "0 4 * * *"
miosa host backup trigger <host> nightly
miosa host backup pause <host> nightly / resume <host> nightly
miosa host backup snapshot list <host> nightly
miosa host backup snapshot get <snapshot>
miosa host backup snapshot fork <snapshot> --to-host <host> --to-path /restore
miosa host backup snapshot rm <snapshot> --yes
miosa host backup rm <host> nightly --yes
```

`miosa host backup new` takes `--path`, `--schedule` (a cron expression), `--timezone`, `--keep` (how many snapshots), `--keep-days`, `--exclude` (repeatable globs) and `--compression` (0-9). `miosa host backup snapshot list` takes `--limit` and `--before`.

### Tunnels

```bash
miosa host tunnel new <host> --port 3000 --access organization
```

Exposes a host port at an address. `--access` is `organization` (default) or `public`, and `--slug` sets the address name.

## Your own cloud

Bring your own cloud (BYOC). Accounts, regions and host pools.

```bash
miosa cloud account new prod --provider aws      # also --provider gcp
miosa cloud accounts
miosa cloud region ...
miosa cloud regions
miosa cloud pool provision <pool> --count 1
miosa cloud pools
miosa cloud nodes
miosa cloud capabilities
miosa cloud preflight run --account <id> --region <id>
miosa cloud preflights
```

Bring your own cloud and host provisioning are a private preview and need host provisioning activated for you.

## AI gateway

Model routing policies, budget, limits and request traces.

```bash
miosa gateway policy new fast --primary-model claude-haiku --alias fast
miosa gateway policy new ... --strategy weighted --fallback-model <model>
miosa gateway budget show
miosa gateway budget ...
miosa gateway limit ...
miosa gateway health
miosa gateway provider-health
miosa gateway environments
miosa gateway requests --model <model> --status <status>
miosa gateway request <id>
miosa gateway settings ...
```

## Raw API

For capabilities broader than the high-level commands, use `miosa api` with the same authenticated config. See [Raw API access](/docs/cli/api).

# JSON output and scripting

URL: https://miosa.ai/docs/cli/scripting
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/scripting
Source: src/routes/docs/cli/scripting/+page.md
Description: Machine-readable output, streaming, error shapes, exit codes and CI patterns for the miosa CLI.

## Machine-readable output

`--json` (or `-o json`, or `MIOSA_OUTPUT=json`) prints machine-readable JSON on stdout.

```bash
miosa list --json | jq -r '.data[].name'
miosa create ci-box --wait --json | jq -r .id
```

Output is never switched to JSON automatically when piped. Commands that stream print one JSON object per line.

## Errors

Errors go to stderr with the API error code. With `--json` they are an `{"error":{...}}` object.

```bash
if ! miosa exec my-box --json -- ./flaky.sh > out.json 2> err.json; then
  jq -r '.error.code' err.json
fi
```

Destructive commands need `--yes` when there is no terminal.

## Exit codes

| Code | Meaning |
|---|---|
| 0 | Success |
| 1 | Error |
| 2 | Usage |
| 3 | Not signed in, or forbidden |
| 4 | Not found |
| 5 | Conflict or invalid input |
| 6 | Rate limited (after retries) |
| 7 | Server or network error |

`miosa exec` and `miosa ssh` exit with the remote command's status, so they drop straight into a pipeline:

```bash
miosa exec ci-box -- npm test || echo "tests failed with $?"
```

## Retries and timeouts

`--retries` (default 3) retries on 429 and transient 5xx. `--timeout` bounds a request in seconds, and for `exec` and `ssh` it also bounds the command (1 to 300).

## A CI pattern

```bash
export MIOSA_API_KEY="$MIOSA_CI_KEY"
miosa create "ci-${CI_PIPELINE_ID}" --size small --ttl 1h --wait --json | jq -r .id
miosa exec "ci-${CI_PIPELINE_ID}" -- ./build.sh
status=$?
miosa destroy "ci-${CI_PIPELINE_ID}" --yes
exit $status
```

## Raw calls from scripts

`miosa api` uses the same credentials and prints the body:

```bash
miosa api GET /sandboxes/ci-box/ports --json | jq -r '.data[].port'
miosa api POST /webhooks -d @hook.json
```

For non-interactive use, set `MIOSA_API_KEY` and avoid browser login entirely. See [Config and profiles](/docs/cli/config) for profiles and credential order.

# Snapshots, checkpoints and restore

URL: https://miosa.ai/docs/cli/snapshots
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/snapshots
Source: src/routes/docs/cli/snapshots/+page.md
Description: Browse, name, fork and delete snapshots of sandboxes and computers, plus checkpoints and restore.

## Snapshots

`miosa snapshot` works on sandboxes and computers alike. Every snapshot of a machine is its history. A named snapshot is a restore point you pin on purpose: it outlives the machine and never appears in history. Each organization keeps 10 named snapshots free.

```bash
miosa snapshot list my-box
miosa snapshot save my-box before-upgrade
miosa snapshot fork before-upgrade
miosa snapshot latest my-box
```

| Command | What it does |
|---|---|
| `miosa snapshot list [machine]` | History across machines, or for one; `--search`, `--workspace`, `--limit` |
| `miosa snapshot named` | Named snapshots and the free allowance |
| `miosa snapshot save <machine> <name>` | Pin a machine (running: captured now, stopped: its newest snapshot) under a name |
| `miosa snapshot save --snapshot <id> <name>` | Pin one existing snapshot |
| `miosa snapshot rm <name>` | Remove a name |
| `miosa snapshot latest <machine>` | Newest snapshot of a machine |
| `miosa snapshot info <id>` | One snapshot and what depends on it |
| `miosa snapshot tree <id> [path]` | List files inside a snapshot, machine stopped or gone |
| `miosa snapshot pull <id> <path> -d ./out` | Download a file, or a folder (extracted from a tar), without overwriting |
| `miosa snapshot fork <id>` | New machine from a snapshot |
| `miosa snapshot fork --name <name>` | New machine from a named snapshot |
| `miosa snapshot delete <id>... \| --all <machine>` | Delete what you name; anything still depended on is skipped and reported |

Deleting needs `--yes` when there is no terminal. Use `--computer` when the machine argument is a computer. `miosa snapshot save` captures a running machine now (waiting with `--wait`, on by default) or the newest snapshot of a stopped one.

## Checkpoints

Checkpoints are sandbox-local restore points.

```bash
miosa checkpoint create my-box --comment "before deps"
miosa checkpoint list my-box
miosa checkpoint info <checkpoint>
miosa checkpoint delete <checkpoint>
```

## Restore

```bash
miosa restore my-box <checkpoint>
```

Restores a sandbox from a checkpoint.

Snapshots are the portable, cross-machine history and the basis for forking. Checkpoints are the quick sandbox-local restore points. Use `miosa snapshot` when you want to move or fork a machine, and `miosa checkpoint` for a fast rollback in place.

# Run commands and move files

URL: https://miosa.ai/docs/cli/work-inside
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cli/work-inside
Source: src/routes/docs/cli/work-inside/+page.md
Description: exec, ssh, console, files, background processes, services, logs, ports and public previews in a sandbox.

## exec

```bash
miosa exec [name|id] -- <cmd> [args...] [flags]
```

Run a command inside a sandbox and print its output. `miosa` exits with the remote command's exit code, so it drops straight into scripts and CI. The `--` separator is required before the command.

```bash
miosa exec my-box -- echo hello
miosa exec -- ls -la /home                              # uses the current sandbox
miosa exec my-box --cwd my-repo -- npm run build
miosa exec my-box -- bash -c 'for i in 1 2 3; do echo $i; done'
```

`--cwd` sets the working directory, relative to the sandbox home directory (or absolute).
`exec` streams output until the command finishes.
For work that runs a long time, start it in the background so it keeps running after you disconnect.

A sandbox that is still starting refuses commands. `exec` retries with backoff until it is ready, up to 90 seconds.

## ssh

```bash
miosa ssh my-box
miosa ssh my-box -- bash -lc "cd app && npm test"
miosa ssh my-box -- bash -s < ./setup.sh
```

`miosa ssh` runs the system `ssh` through the authenticated tunnel with a one-time key and a short-lived certificate (15 minutes, valid for that sandbox only). Where the server has no certificate authority it authorizes the one-time key in the sandbox instead. The key, certificate and host file live in a private temporary directory removed when ssh ends.

Standard input is piped through, up to 80KB. `--api` runs the command over the MIOSA API instead, and so does a machine without `ssh`. There is no interactive login shell yet.

`ssh user@host` and `scp` against a sandbox directly do not work: there is no public SSH endpoint.

## console

```bash
miosa console my-box
```

An interactive shell in a sandbox using the miosa-terminal-v1 WebSocket relay, with a real PTY, resize handling and the remote exit code.

## files

```bash
miosa files [command]
```

Remote paths are written `<sandbox>:<path>`. The sandbox may be a name or id, and can be omitted for the current sandbox. Relative remote paths start in `/home/user`.

```bash
miosa files ls my-box:/workspace
miosa files cp ./app.py my-box:/workspace/app.py
miosa files cp -r ./src my-box:/workspace/
miosa files cp my-box:/workspace/out.json ./out.json
miosa files cat my-box:/workspace/out.json
cat config.yaml | miosa files write my-box:/workspace/config.yaml
```

| Command | What it does |
|---|---|
| `files ls [-l] <path>` | List a directory (`-l` shows modification times) |
| `files cp [-r] <src> <dst>` | Copy local to remote, remote to local, or remote to remote |
| `files cat <path>` | Print a file |
| `files write <path>` | Write stdin to a file, creating parent directories |
| `files mkdir <path>` | Create a directory and its parents |
| `files mv <from> <to>` | Move or rename (alias `rename`) |
| `files rm [-r] [-f] <path>...` | Delete files or directories |
| `files chmod <mode> <path>` | Change permissions (octal, for example `755`) |
| `files stat <path>` | Type, size, mode and modification time |

A directory needs `-r`. A path that does not exist is an error unless `-f` is given.

## Background processes

```bash
miosa process start --name build --cwd /workspace/app -- npm run build
miosa process list
miosa ps
miosa process logs <pid> --tail 50
miosa process kill <pid>
miosa process get <pid>
```

`miosa ps` is the same as `miosa process list`.

## Daemons

A sandbox daemon is a named long-lived process: start it with a name, then read
its output, restart it or stop it by that name.

```bash
miosa daemon create my-box --name web --command "npm run dev" --cwd /workspace/app
miosa daemon list my-box
miosa daemon logs my-box web
miosa daemon restart my-box web
miosa daemon stop my-box web
```

Named services belong to a Computer, where systemd owns them; `miosa services`
is the project Services command and does not take sandbox flags.

## Logs and events

```bash
miosa logs my-box -n 100 -f     # system log, follow
miosa events my-box             # stream lifecycle events
```

## Ports, previews and URLs

```bash
miosa ports my-box
miosa preview create my-box 3000 --visibility public
miosa preview list
miosa url my-box
```

`miosa preview` publishes a sandbox port at a public URL and is where visibility
is decided: `--visibility private|public`, `--ttl`, `--name`. `miosa url` prints
the URL a sandbox's endpoint answers on, and `miosa preview unshare` revokes a
public link.

## Proxy

```bash
miosa proxy my-box 5432:5432
```

Forwards local ports to sandbox ports over a WebSocket tunnel (any TCP service; the key needs `sandboxes:exec`).

## Desktop

```bash
miosa desktop start my-box
miosa desktop url my-box
```

Running a command over the API and over ssh have the same exit-code behaviour: both exit with the remote command's status.

# MIOSA vs other platforms

URL: https://miosa.ai/docs/compare
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare
Source: src/routes/docs/compare/+page.md
Description: How MIOSA compares to Railway, Render, Fly.io, E2B, Daytona, Modal, Vercel, Cloudflare, Freestyle, Runloop, Blaxel, Beam, boat and CodeSandbox, using independent benchmark data and each vendor's public documentation as of 2026-10-23.

<div style="margin:-0.5rem 0 2rem;"></div>

MIOSA is a runtime platform for AI products. The platforms below are the ones it is
most often measured against. This section is meant to help you pick the right tool,
not to score points: several of these products are excellent at what they do, and for
some jobs one of them is the better choice.

Two kinds of evidence appear here and nowhere else:

- **Measured performance** from the independent [ComputeSDK benchmark](/docs/benchmarks),
  run the same way against every provider. The latest figures are from **October 23, 2026**.
- **Product capabilities** that MIOSA documents in this site, each linked.

Competitor descriptions use each vendor's **own public documentation** and are stated
**as of October 2026**. Vendor docs and pricing change; check them before you decide.

## Where MIOSA stands

In the latest independent run (ComputeSDK, October 23, 2026), MIOSA ranked **#1 of 32** on
sandbox burst startup, the time from a create request to the first successful command
inside a fresh sandbox, under 100 concurrent creates:

| Metric | MIOSA | Date |
|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms** (#1 of 32) | 2026-10-23 |
| Burst startup, p95 / p99 | 68.81 ms / 72.20 ms | 2026-10-23 |
| Burst startup, success | 100 / 100 | 2026-10-23 |

Every figure is a committed JSON file in the open ComputeSDK repository. See
[Benchmarks](/docs/benchmarks) for the full leaderboard, method, and reproduction steps.

## Sandbox startup, side by side

The same independent benchmark, same workload, same date. Lower is better.

| Provider | Burst startup, median | Rank (of 32) | As of |
|---|---|---|---|
| **MIOSA** | **57.09 ms** | **#1** | 2026-10-23 |
| isorun | 74.93 ms | #2 | 2026-10-23 |
| Blaxel | 441.82 ms | #7 | 2026-10-23 |
| Beam | 707.07 ms | #11 | 2026-10-23 |
| Cloudflare Sandboxes | 682.13 ms | #12 | 2026-10-23 |
| Vercel Sandbox | 718.35 ms | #15 | 2026-10-23 |
| Modal | 1070.58 ms | #17 | 2026-10-23 |
| Daytona | 1094.64 ms | #19 | 2026-10-23 |
| E2B | 1439.39 ms | #20 | 2026-10-23 |
| Freestyle | 3237.49 ms | #28 | 2026-10-23 |
| CodeSandbox | 33771.52 ms | #29 | 2026-10-23 |

Source: ComputeSDK burst TTI, 2026-10-23, via [our benchmark page](/docs/benchmarks).
Runloop and boat do not appear in this run. These are one independent benchmark of one metric
under load; they are not a verdict on each product's overall fit.

## Full-build workload (DAX)

The DAX suite measures a full production build inside a fresh sandbox: clone, install,
typecheck, timed end to end. Lower is better. On the most recent run (October 23, 2026)
MIOSA was **#3 of 22** at 38.8 s; on the August 28, 2026 run MIOSA was **#1**.

| Provider | 2026-08-28 | 2026-10-23 |
|---|---|---|
| **MIOSA** | **39.3 s (#1 of 19)** | **38.8 s (#3 of 22)** |
| isorun | 39.5 s | 37.3 s (#2) |
| Blaxel | 45.6 s | no result |
| Beam | no result | 91.4 s (#19) |
| Vercel Sandbox | 69.7 s | no result |
| Daytona | 141.3 s | 79.5 s (#15) |
| E2B | 72.0 s | 75.0 s (#14) |
| Modal | 97.7 s | 82.3 s (#16) |
| Runloop | 114.4 s | not listed |
| CodeSandbox | 81.2 s | no result |

MIOSA's 2026-10-09 DAX run, the one that did not complete.

## What MIOSA adds

Some providers here list a lower hourly price for a bare machine.
That price buys the machine only; hosting, databases, agents, tenants and billing come from other services you add yourself.
MIOSA's price covers the platform around the machine, so you can build, deploy and run a full-stack, multi-tenant product in one place.
If all you need is a raw sandbox, a sandbox-only provider may suit you better.
See [why some providers list a lower hourly price](/docs/pricing#why-some-providers-list-a-lower-hourly-price).

Beyond the sandbox itself, these are the capabilities this site documents, and where
each competitor sits is best checked in that vendor's own docs:

- **Persistent computers with full Linux desktops** - browser, mouse, keyboard, screenshots,
  and human handoff, not just a headless shell. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host** - ship a sandbox to an immutable, versioned URL, or run
  many customer apps as containers. See [Deployments](/docs/docker-host/overview).
- **White-label platform** - your brand, domains, tenants, and end users on top of MIOSA.
  See [White-label setup](/docs/platform/white-label).
- **One interface for everyone** - MCP, a CLI, and six SDKs over the same API. See
  [MCP](/docs/mcp), [CLI](/docs/cli), and [SDKs](/docs/sdks).
- **Managed data** - Postgres, MySQL, Redis, MongoDB, and Qdrant with connection injection. See
  [Data](/docs/data/overview).
- **Regions and your own hardware** - MIOSA-managed regions and OpenComputers for machines
  you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## The comparisons

Two groups. **Deploy platforms** - Railway, Render and Fly.io - run apps and
services from a repository, which is the job Services does. **Sandbox platforms** -
E2B, Daytona, Modal, Vercel, Cloudflare, Freestyle, Runloop, Blaxel, Beam, boat
and CodeSandbox - run sandboxes for code and agents, which is the job Sandboxes does.
Each sandbox page has a capabilities table with a source link for every competitor answer.

Moving from one of them? The [Railway migration guide](/docs/migrate/railway) is the
written one today, and `miosa import railway` produces a reviewable plan without
copying secret values.

## Independent comparisons

For a broader, third-party view of the market, see
[**battleships.dev**](https://battleships.dev). It is a pricing estimator and comparison
site for cloud runtime, sandbox, and agent-compute platforms, with feature matrices and
machine-readable data. It is not neutral: it is built by boat.dev, a competing sandbox
provider, which states that all providers use the same engine and rules. We link to it as
a resource and do not quote its MIOSA figures, which have been wrong in the past; use it
to explore the field, and verify any number against the vendor.

Performance figures are the independent ComputeSDK benchmark, not our own testing, and
they measure startup and build time under load. Capability differences are the ones this
documentation can prove for MIOSA. Competitor capabilities are described from their public
docs as of October 2026 and should be verified with the vendor before you buy. If a claim
is uncertain, it is not made here.

# MIOSA vs Beam

URL: https://miosa.ai/docs/compare/beam
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/beam
Source: src/routes/docs/compare/beam/+page.md
Description: A factual comparison of MIOSA and Beam, using the independent ComputeSDK benchmark and Beam's public documentation as of October 2026.

## What Beam is

Beam ("On-Demand AI Compute") provides serverless sandboxes for running code and models, described in its public documentation at ([beam.cloud](https://beam.cloud), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Beam | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 707.07 ms (#11) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | no result | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | 91.4 s (#19) | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Beam performs well on the DAX build workload. These figures measure startup and build time under load only.

## Capabilities side by side

Each Beam answer comes from Beam's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

| Regions | [us-east, us-west, us-mia](/docs/regions) | United States by default | [Beam docs](https://docs.beam.cloud/v2/security/security.md) |

## Where MIOSA differs

These capabilities are documented for MIOSA on this site:

- **Persistent computers with a full Linux desktop**, not only headless sandboxes. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host**, so a machine becomes a versioned URL or a containerized app. See [Deployments](/docs/docker-host/overview).
- **White-label platform**, so your customers see your brand and domains. See [White-label setup](/docs/platform/white-label).
- **One interface for everyone**: MCP, a CLI, and six SDKs. See [MCP](/docs/mcp), [CLI](/docs/cli), [SDKs](/docs/sdks).
- **Managed data** with connection injection: Postgres, MySQL, Redis, MongoDB, Qdrant. See [Data](/docs/data/overview).
- **Regions and OpenComputers** for machines you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## When to choose each

- **Choose Beam** if you want serverless sandboxes for code and models and a GPU-adjacent compute platform.
- **Choose MIOSA** if you want sandboxes, full computers, agent runs, deployments, and managed data in one platform, with the measured startup figures above.

# MIOSA vs Blaxel

URL: https://miosa.ai/docs/compare/blaxel
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/blaxel
Source: src/routes/docs/compare/blaxel/+page.md
Description: A factual comparison of MIOSA and Blaxel, using the independent ComputeSDK benchmark and Blaxel's public documentation as of October 2026.

## What Blaxel is

Blaxel ("Infrastructure for autonomous agents") provides agent infrastructure for running code in sandboxes, described in its public documentation at ([blaxel.ai](https://www.blaxel.ai), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Blaxel | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 441.82 ms (#7) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | 45.6 s (#4) | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | no result | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Blaxel ranks well on the DAX build workload and is competitive on it. These figures cover startup and build time under load only, not API design, pricing, or fit.

## Capabilities side by side

Each Blaxel answer comes from Blaxel's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

## Where MIOSA differs

These capabilities are documented for MIOSA on this site:

- **Persistent computers with a full Linux desktop**, not only headless sandboxes. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host**, so a machine becomes a versioned URL or a containerized app. See [Deployments](/docs/docker-host/overview).
- **White-label platform**, so your customers see your brand and domains. See [White-label setup](/docs/platform/white-label).
- **One interface for everyone**: MCP, a CLI, and six SDKs. See [MCP](/docs/mcp), [CLI](/docs/cli), [SDKs](/docs/sdks).

- **Regions and OpenComputers** for machines you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## When to choose each

- **Choose Blaxel** if you want agent infrastructure focused on running autonomous agents, and the DAX build numbers are the metric you care about.
- **Choose MIOSA** if you want measured-fast sandbox startup plus computers with desktops, agent runs, deployments, managed data, and a branded platform in one place.

# MIOSA vs boat

URL: https://miosa.ai/docs/compare/boat
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/boat
Source: src/routes/docs/compare/boat/+page.md
Description: A factual comparison of MIOSA and boat (boat.dev), cloud sandboxes for AI agents, using boat's public documentation as of 2026-10-23.

Every boat statement below is from boat's own public site and documentation ([boat.dev](https://boat.dev), [docs.boat.dev](https://docs.boat.dev)), read on 2026-10-23.
MIOSA statements link to the page that documents them.

## What boat is

boat is a cloud sandbox product for AI agents: persistent Ubuntu VMs with SSH, Docker inside, a desktop, and disk-level forks from snapshots ([boat.dev](https://boat.dev)).
It was called Box until 2026-09-15; the old `box` CLI and endpoints still work until 2026-10-31 ([migrating from Box](https://docs.boat.dev/migrating-from-box.md)).
It is a sandbox product, not a deploy platform: there is no deploy, custom domain, rollback, or managed database command ([always-on services](https://docs.boat.dev/long-running-tasks/always-on-services.md), [host CLI](https://docs.boat.dev/hosting/host-cli.md)).

boat does not appear in the ComputeSDK runs our [benchmark page](/docs/benchmarks) reports, so this page has no measured comparison.

## Capabilities side by side

| Capability | MIOSA | boat | boat source |
|---|---|---|---|
| Persistent Linux machines | [Yes, sandboxes and computers](/docs/sandboxes-or-computers) | Yes, Ubuntu VMs with SSH | [boat.dev](https://boat.dev) |
| Docker inside the machine | [Yes](/docs/develop/sandboxes/docker) | Yes | [boat.dev](https://boat.dev) |
| Full desktop | [Yes, Computers](/docs/computers/overview) | Yes | [boat.dev](https://boat.dev) |

| Billing | [Per second while running, one price per size](/docs/pricing) | Per second while running; plans from $20 to $2000 a month come back as compute | [pricing](https://docs.boat.dev/pricing) |
| Regions | [us-east, us-west, us-mia](/docs/regions) | EU only | [pricing](https://docs.boat.dev/pricing) |

## Where boat leads

These are real differences, from boat's documentation:

- **Install signs you in.** The install script opens sign-in and checkout in one step ([quickstart](https://docs.boat.dev/quickstart.md)); MIOSA installs the CLI, then `miosa login` is a second step.
- **Agent self-sign-up is a documented protocol**, with a split start-then-wait login for agents ([agent auth](https://docs.boat.dev/agent-auth.md)).
- **Long commands.** `boat exec --timeout 0` runs without a limit and can detach and re-attach.
- **JSON output switches on when output is piped** ([CLI reference](https://docs.boat.dev/cli-reference.md)); MIOSA needs `--json`.
- **Fan-out from a snapshot** with `--count` up to 1000, and **per-sandbox variables** on create (`-e KEY=VALUE`).
- **Command history** with output, per sandbox (`boat history`).

## Where MIOSA differs

- **Deploy is a product**, not a recipe: deploy from a repository, a directory, or a sandbox, with releases, promote and rollback. See [Services](/docs/services/overview).
- **Custom domains** with DNS verification. See [Domains](/docs/services/domains).
- **Managed databases** with backups and connection strings. See [Databases](/docs/data/overview).
- **Live resize** of a running sandbox, and **checkpoints and restore**. See [Sizing](/docs/develop/sandboxes/sizing) and [Snapshots](/docs/develop/snapshots).
- **One interface for everyone**: MCP, a CLI, and six SDKs. See [MCP](/docs/mcp), [CLI](/docs/cli), [SDKs](/docs/sdks).
- **US regions**, and bring your own cloud on AWS and Google Cloud. See [Regions](/docs/regions) and [BYOC](/docs/infrastructure/byoc/overview).

## When to choose each

- **Choose boat** if you want EU-hosted sandboxes with SSH, unlimited-length commands, and a one-step agent sign-up, and you do not need deploys, domains, or databases from the same product.
- **Choose MIOSA** if you want sandboxes, full computers, deployments, domains, and managed data on one platform, in US regions.

boat's compare page lists MIOSA once, as "full VMs with /dev/kvm and no 24-hour timeout" ([boat.dev/compare](https://boat.dev/compare)).
boat also builds [battleships.dev](https://battleships.dev), a third-party-looking comparison site; see [the Compare overview](/docs/compare#independent-comparisons).

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/cloudflare
Source: src/routes/docs/compare/cloudflare/+page.md
Description: A factual comparison of MIOSA and Cloudflare Sandboxes, using the independent ComputeSDK benchmark and Cloudflare Sandboxes's public documentation as of October 2026.

## What Cloudflare Sandboxes is

Cloudflare's Sandbox SDK runs sandboxed code execution on Cloudflare's edge, described in its public documentation at ([developers.cloudflare.com/sandbox](https://developers.cloudflare.com/sandbox/), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Cloudflare Sandboxes | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 682.13 ms (#12) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | no result | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | 155.9 s (#21) | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Cloudflare's strength is the edge network and its integration with Workers. Where your architecture is already edge-first, that integration can outweigh a startup-time gap.

## Capabilities side by side

Each Cloudflare Sandboxes answer comes from Cloudflare Sandboxes's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

## Where MIOSA differs

These capabilities are documented for MIOSA on this site:

- **Persistent computers with a full Linux desktop**, not only headless sandboxes. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host**, so a machine becomes a versioned URL or a containerized app. See [Deployments](/docs/docker-host/overview).
- **White-label platform**, so your customers see your brand and domains. See [White-label setup](/docs/platform/white-label).
- **One interface for everyone**: MCP, a CLI, and six SDKs. See [MCP](/docs/mcp), [CLI](/docs/cli), [SDKs](/docs/sdks).
- **Managed data** with connection injection: Postgres, MySQL, Redis, MongoDB, Qdrant. See [Data](/docs/data/overview).
- **Regions and OpenComputers** for machines you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## When to choose each

- **Choose Cloudflare Sandboxes** if you build on Cloudflare Workers and want code execution close to your edge compute and data.
- **Choose MIOSA** if you want a runtime that covers sandboxes, full computers, agent runs, deployments, and managed data in one place, with a branded tenant surface and the measured startup figures above.

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/codesandbox
Source: src/routes/docs/compare/codesandbox/+page.md
Description: A factual comparison of MIOSA and CodeSandbox, using the independent ComputeSDK benchmark and CodeSandbox's public documentation as of October 2026.

## What CodeSandbox is

CodeSandbox provides instant cloud development environments and sandboxes, described in its public documentation at ([codesandbox.io](https://codesandbox.io), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | CodeSandbox | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 33771.52 ms (#29) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | 81.2 s (#13) | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | no result | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

The burst number here is under heavy concurrency; CodeSandbox is a mature product for interactive development that this benchmark does not fully represent.

## Capabilities side by side

Each CodeSandbox answer comes from CodeSandbox's own documentation, linked in the last column. codesandbox.io blocks automated fetches, so these answers were read from the archived copy of 2026-04-21 and may be out of date.
Each MIOSA answer links the page that documents it.

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/daytona
Source: src/routes/docs/compare/daytona/+page.md
Description: A factual comparison of MIOSA and Daytona, using the independent ComputeSDK benchmark and Daytona's public documentation as of October 2026.

## What Daytona is

Daytona provides sandboxes and infrastructure for running AI-generated code, described in its public documentation at ([daytona.io/docs](https://www.daytona.io/docs), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Daytona | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 1094.64 ms (#19) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | 141.3 s | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | 79.5 s (#15) | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Startup and build time are two metrics under load. Daytona’s build time improved to 70.0 s on the latest run, and these figures do not capture API design, pricing, or fit.

## Capabilities side by side

Each Daytona answer comes from Daytona's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

Description: A factual comparison of MIOSA and E2B, using the independent ComputeSDK benchmark and E2B's public documentation as of October 2026.

## What E2B is

E2B provides open-source sandboxes for AI agents to execute code, described in its public documentation at ([e2b.dev/docs](https://e2b.dev/docs), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

These numbers measure startup and build time under load only. They say nothing about correctness, API design, pricing, or support, where E2B may well be the better fit for your team.

## Capabilities side by side

Each E2B answer comes from E2B's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.

# MIOSA vs Fly.io

URL: https://miosa.ai/docs/compare/fly
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/fly
Source: src/routes/docs/compare/fly/+page.md
Description: A factual comparison of MIOSA and Fly.io for running apps and machines, using Fly.io's public documentation as of 2026-10-23.

Every competitor statement is from Fly.io's own public documentation ([fly.io/docs](https://fly.io/docs), as of 2026-10-23). MIOSA statements link to the page that documents them. Where MIOSA has no equivalent, the row says so.

## Workloads

| Capability | MIOSA | Fly.io |
|---|---|---|
| Long-running app from an image or repository | Yes, Services run modes `server`, `worker`, `cron`, `static` | Yes, apps on Machines |
| Direct control of a VM | Yes, Computers with a full Linux desktop | Yes, Machines |
| Ephemeral code execution | Yes, Sandboxes | Not the documented model; Machines are long-lived by default |
| Config as code | `miosa.json` / `miosa.app.yml` | `fly.toml` |
| Multiple regions | `us-east`, `us-west`, `us-mia` | A wider published region list |

Sources: [services](/docs/services/overview), [computers](/docs/computers/overview), [sandboxes](/docs/develop/sandboxes), and Fly.io's [Machines](https://fly.io/docs/machines/) and [fly.toml reference](https://fly.io/docs/reference/configuration/).

## Networking and data

| Capability | MIOSA | Fly.io |
|---|---|---|
| Private networking between a project's services | Same host today; wider private networking is not generally available | Documented private networking across a region |
| Public address per service | Yes, `<label>.<org>.miosa.app`, plus custom domains | Yes, `*.fly.dev` plus certificates |
| Managed Postgres, MySQL, Redis, MongoDB | Yes | Managed Postgres is documented; other engines are run by you |
| Public database endpoint with an allowlist | Yes, TLS only | Connections are documented through your own proxy or app |

Sources: [custom domains](/docs/docker-host/domains), [databases](/docs/data/overview), [public endpoint](/docs/data/public-endpoint).

## What MIOSA does not have

- **Fly.io's region coverage.** Three regions, named above; nothing else is claimed.
- **Cross-host private networking between services.** Same-host private networking works today.

## When to choose each

- **Choose Fly.io** if you need its region footprint or you already run your networking around it.
- **Choose MIOSA** if your product also needs sandboxes and agent workloads, a console for customers of your own, or one platform for machines, services and data.

Both products change. The links above are what this page was written from on 2026-10-23.

# MIOSA vs Freestyle

URL: https://miosa.ai/docs/compare/freestyle
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/freestyle
Source: src/routes/docs/compare/freestyle/+page.md
Description: A factual comparison of MIOSA and Freestyle, using the independent ComputeSDK benchmark and Freestyle's public documentation as of October 2026.

## What Freestyle is

Freestyle (freestyle.sh) provides "Full Linux VMs for AI Agents", aimed at agent platforms and app builders, described in its public documentation at ([freestyle.sh](https://freestyle.sh), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Freestyle | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 3237.49 ms (#28) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | not listed | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | no result | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Startup time under load is one metric. Freestyle leads on several capabilities MIOSA does not offer (below), and its own "ready in 65 ms" figure is measured by Freestyle, not by this benchmark. Compare on fit for your product, not on a single number.

## Capabilities side by side

Each Freestyle answer comes from Freestyle's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

## Where MIOSA differs

These capabilities are documented for MIOSA on this site:

- **Persistent computers with a full Linux desktop**, not only headless sandboxes. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host**, so a machine becomes a versioned URL or a containerized app. See [Deployments](/docs/docker-host/overview).
- **White-label platform**, so your customers see your brand and domains. See [White-label setup](/docs/platform/white-label).
- **One interface for everyone**: MCP, a CLI, and six SDKs. See [MCP](/docs/mcp), [CLI](/docs/cli), [SDKs](/docs/sdks).
- **Managed data** with connection injection: Postgres, MySQL, Redis, MongoDB, Qdrant. See [Data](/docs/data/overview).
- **Regions and OpenComputers** for machines you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## Where Freestyle leads

Freestyle documents capabilities that MIOSA does **not** document today. These are real differences:

- **Nested virtualization**: running K3s or VMs inside the machine. MIOSA runs Docker inside a sandbox ([Docker in sandboxes](/docs/develop/sandboxes/docker)), but does not document nested virtualization.
- **Live clone of a running VM including its memory.** MIOSA snapshots a sandbox and forks from that state, but it does not document a live in-memory clone of a running machine.
- **WireGuard access to private networks.** MIOSA does not document WireGuard private networking as a public capability.
- **A full Debian image with systemd.** MIOSA sandboxes are isolated Linux workspaces; it does not document a systemd-based image as a user-facing feature.

## When to choose each

- **Choose Freestyle** if you specifically need nested virtualization, live-memory cloning, WireGuard private networking, or a full systemd Debian image.
- **Choose MIOSA** if you want measured-fast sandbox startup, persistent computers with a desktop, deployments, managed data, and a white-label multi-tenant surface in one platform. If you need the features in "Where Freestyle leads", Freestyle is the better fit for those.

# MIOSA vs Modal

URL: https://miosa.ai/docs/compare/modal
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/modal
Source: src/routes/docs/compare/modal/+page.md
Description: A factual comparison of MIOSA and Modal, using the independent ComputeSDK benchmark and Modal's public documentation as of October 2026.

## What Modal is

Modal is a serverless cloud platform for running compute for AI workloads, including sandboxed containers, described in its public documentation at ([modal.com/docs](https://modal.com/docs), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Modal | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 1070.58 ms (#17) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | 97.7 s | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | 82.3 s (#16) | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Modal is broader than a sandbox platform: much of what teams use it for (GPU serving, scheduled jobs) is outside this comparison. This page compares only the sandbox workload the benchmark measures.

## Capabilities side by side

Each Modal answer comes from Modal's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

|---|---|---|---|
| Isolation | [Firecracker microVM by default](/docs/develop/sandboxes) | gVisor, or a VM runtime | [Modal docs](https://modal.com/docs/guide/sandboxes.md) |
| Sandbox lifetime | [Idle timeout, 1 hour by default and up to 24 hours, extendable; computers persist](/docs/develop/sandboxes/timeouts) | 5 minutes by default, up to 24 hours | [Modal docs](https://modal.com/docs/guide/sandboxes.md) |
| Pause, snapshots, forks | [Yes: pause and resume, snapshots, restore and fork](/docs/develop/snapshots) | Snapshots; no pause and resume | [Modal docs](https://modal.com/docs/guide/sandbox-snapshots) |
| Full Linux desktop and computer use | [Yes, Computers](/docs/computers/overview) | As an example (VNC in a VM sandbox), not a product | [Modal docs](https://modal.com/docs/examples/computer_use_vnc.md) |
| Public preview URL for a port | [Yes](/docs/develop/previews) | Yes, tunnels | [Modal docs](https://modal.com/docs/guide/sandbox-networking) |
| Deploy to a production URL | [Yes, Services and Docker Host, with releases and rollback](/docs/services/overview) | Not for sandboxes; apps deploy with modal deploy | [Modal docs](https://modal.com/docs/guide/sandboxes.md) |

| Billing | [Per second while running, one price per size](/docs/pricing) | Per second, per core and GiB | [Modal docs](https://modal.com/pricing) |
| Regions | [us-east, us-west, us-mia](/docs/regions) | Many, at a price multiplier; region routing does not apply to sandboxes | [Modal docs](https://modal.com/docs/guide/region-selection) |

## Where MIOSA differs

These capabilities are documented for MIOSA on this site:

- **Persistent computers with a full Linux desktop**, not only headless sandboxes. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host**, so a machine becomes a versioned URL or a containerized app. See [Deployments](/docs/docker-host/overview).
- **White-label platform**, so your customers see your brand and domains. See [White-label setup](/docs/platform/white-label).

- **Regions and OpenComputers** for machines you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## When to choose each

- **Choose Modal** if you need serverless GPU compute, model serving, or general batch infrastructure alongside sandboxes.
- **Choose MIOSA** if your product is agent- and app-shaped: sandboxes, full computers, agent runs, deployments, managed data, and a white-label surface, with the measured startup figures above.

# MIOSA vs Railway

URL: https://miosa.ai/docs/compare/railway
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/railway
Source: src/routes/docs/compare/railway/+page.md
Description: A factual comparison of MIOSA and Railway for running services, using Railway's public documentation as of 2026-10-23.

Every competitor statement below is from Railway's own public documentation ([docs.railway.com](https://docs.railway.com), as of 2026-10-23). MIOSA statements link to the page that documents them. Where MIOSA has no equivalent, the row says so.

## Services

| Capability | MIOSA | Railway |
|---|---|---|
| Web service from a repository | Yes, with a public address | Yes |
| Background worker | Yes, run mode `worker` | Yes |
| Scheduled job | Yes, run mode `cron` with a five-field schedule | Yes |
| Static site | Yes, built from git and served from the static lane | Yes |
| Per-pull-request preview | Yes, one per pull request, with the same cap and TTL controls | Yes, PR environments |

Sources: [databases](/docs/data/overview), [public endpoint](/docs/data/public-endpoint), [variables](/docs/services/variables).

## What MIOSA does not have

- **Cross-host private networking between services.** Same-host private networking works today; anything wider is not generally available, and this page will not claim otherwise.
- **Railway's full region list.** MIOSA runs in `us-east`, `us-west` and `us-mia`.

## When to choose each

- **Choose Railway** if you want its wider region set or you are already settled there.
- **Choose MIOSA** if you also want full Linux computers and sandboxes on the same platform, one set of credentials, and a white-label surface for your own customers.

Both products change. The links above are the documents this page was written from on 2026-10-23; read them, then decide.

Moving? [Read the Railway migration guide](/docs/migrate/railway), and `miosa import railway` writes a reviewable plan from a Railway project without copying secret values.

- **Cross-host private networking between services.** Same-host private networking works today; anything wider is not generally available.
- **Render's region list.** MIOSA runs in `us-east`, `us-west` and `us-mia`.

## When to choose each

- **Choose Render** if its regions or its Blueprint workflow fit your team already.
- **Choose MIOSA** if you also want full Linux computers and sandboxes beside the services, one credential set, and a white-label surface for your own customers.

Both products change. The links above are what this page was written from on 2026-10-23.

Moving? Start with [deploy a service](/docs/services/quickstart); `miosa import` reads a Railway project today, and the same plan format is what other importers will write.

# MIOSA vs Runloop

URL: https://miosa.ai/docs/compare/runloop
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/runloop
Source: src/routes/docs/compare/runloop/+page.md
Description: A factual comparison of MIOSA and Runloop, using the independent ComputeSDK benchmark and Runloop's public documentation as of October 2026.

## What Runloop is

Runloop ("Your AI Agent Accelerator") provides devboxes and sandboxes for AI coding agents, described in its public documentation at ([runloop.ai](https://runloop.ai), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Runloop | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | not listed | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | 114.4 s (#16) | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | not listed | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

Runloop does not appear in the latest burst run, so there is no like-for-like startup number here. Compare on the workloads and capabilities that matter to you.

## Capabilities side by side

Each Runloop answer comes from Runloop's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

## When to choose each

- **Choose Runloop** if you want managed devboxes tuned for coding agents and a focused agent-infrastructure product.
- **Choose MIOSA** if you want sandboxes, full computers with a desktop, agent runs, deployments, managed data, and a white-label surface in one platform, with the measured figures above.

# MIOSA vs Vercel Sandbox

URL: https://miosa.ai/docs/compare/vercel
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/compare/vercel
Source: src/routes/docs/compare/vercel/+page.md
Description: A factual comparison of MIOSA and Vercel Sandbox, using the independent ComputeSDK benchmark and Vercel Sandbox's public documentation as of October 2026.

## What Vercel Sandbox is

Vercel Sandbox runs ephemeral compute for AI agents as part of the Vercel platform, described in its public documentation at ([vercel.com/docs/vercel-sandbox](https://vercel.com/docs/vercel-sandbox), as of October 2026).

## Measured performance

The independent ComputeSDK benchmark runs the same workload against every provider. That is the only apples-to-apples number here.

| Metric | MIOSA | Vercel Sandbox | As of |
|---|---|---|---|
| Burst startup, median time-to-interactive | **57.09 ms (#1 of 32)** | 718.35 ms (#15) | 2026-10-23 |
| DAX full build, 2026-08-28 | **39.3 s (#1 of 19)** | 69.7 s | 2026-08-28 |
| DAX full build, 2026-10-23 | **38.8 s (#3 of 22)** | no result | 2026-10-23 |

Source: ComputeSDK, via [our benchmark page](/docs/benchmarks). Burst startup is the time from a create request to the first successful command inside a fresh sandbox, under 100 concurrent creates. Where a run is not listed, the provider did not appear in that run.

If your product already lives on Vercel, keeping the sandbox and the hosting in one vendor is a real benefit that no benchmark captures. Compare on fit, not only on milliseconds.

## Capabilities side by side

Each Vercel Sandbox answer comes from Vercel Sandbox's own documentation or pricing page, linked in the last column, fetched on 2026-10-23.
Each MIOSA answer links the page that documents it.
"Not documented" means the vendor's docs do not say, not that the feature is missing.

## Where MIOSA differs

These capabilities are documented for MIOSA on this site:

- **Persistent computers with a full Linux desktop**, not only headless sandboxes. See [Computers](/docs/computers/overview).
- **Deployments and Docker Host**, so a machine becomes a versioned URL or a containerized app. See [Deployments](/docs/docker-host/overview).
- **White-label platform**, so your customers see your brand and domains. See [White-label setup](/docs/platform/white-label).
- **One interface for everyone**: MCP, a CLI, and six SDKs. See [MCP](/docs/mcp), [CLI](/docs/cli), [SDKs](/docs/sdks).

- **Regions and OpenComputers** for machines you own. See [Regions](/docs/regions) and [OpenComputers](/docs/opencomputers).

## When to choose each

- **Choose Vercel Sandbox** if you are already all-in on Vercel and want the sandbox and the deploy surface under one account and one bill.
- **Choose MIOSA** if you want a platform-independent runtime for sandboxes, computers, agent runs, deployments, and data, with a branded multi-tenant surface and the measured startup figures above.

Description: MIOSA Foundation UI reference with design intent, Tailwind v4 tokens, CSS variables, and design tokens.

MIOSA Foundation is the internal component library for the platform frontend. It is the place to inspect components before deciding what to keep, remove, rename, or rebuild.

This is the product UI system for building MIOSA itself, not the drop-in `@miosa/*` packages that customers import to embed sandboxes in their own apps  -  those are documented in [UI Components](/docs/ui-components).

The live browser is maintained in the Foundation package:

```bash
cd miosa-platform/miosa-frontend/src/lib/foundations-components
npm run dev -- --host 127.0.0.1 --port 5174
```

Open:

```text
http://127.0.0.1:5174/component-library
```

The library is being cleaned up from a broad prototype set into a small, repeatable MIOSA UI system. Treat this page as the design contract for that cleanup work.

## Compact Reference

MIOSA UI should feel like an operator console for AI compute: precise, dark, dense, and fast to scan. Keep the system mostly neutral. Use a limited blue/cyan signal color only for active compute, selected state, focus, and live status. Avoid decorative gradients, oversized marketing sections, duplicate button variants, and one-off component styling.

| Token | Value | Role |
|---|---:|---|
| Canvas | `#07090d` | App background |
| Panel | `#10141c` | Primary component surface |
| Raised | `#151b25` | Elevated controls and selected rows |
| Border | `#263041` | Hairline structure |
| Text | `#f4f7fb` | Primary text |
| Muted | `#8d98aa` | Secondary labels |
| Signal | `#60a5fa` | Active compute, focus, selected state |
| Success | `#34d399` | Healthy/running status |
| Warning | `#fbbf24` | Attention state |
| Danger | `#f87171` | Destructive or failed state |

Core rules:

- Use one primary button per visual region.
- Prefer compact toolbars, segmented controls, tabs, tables, and split panes.
- Use 1px borders for structure; use shadows sparingly.
- Use status color only where state must be read quickly.
- Keep cards at `8px` radius unless the existing local pattern requires less.
- Remove duplicate button/component variants unless they encode meaning.

# MIOSA Foundation UI

Theme: dark operator console

MIOSA Foundation is a component system for AI compute, white-label workspaces,
sandboxes, deployments, file browsers, agents, and usage operations. It should
feel like a precise product surface, not a marketing page.

## Design Character

The UI is compact, structured, and status-rich. Components should look like
they belong in the same control plane: split panes, command bars, tables,
logs, terminals, inspectors, file trees, detail drawers, and focused panels.

The component library should not keep every prototype. It should converge on
the smallest set of primitives and domain components that can compose the real
MIOSA product.

## Keep

- Buttons with clear hierarchy: primary, secondary, ghost, icon, destructive.
- Inputs, selects, textareas, checkboxes, switches, sliders, tabs, menus.
- Tables and data grids for operational records.
- Split panes for preview + files, terminal + logs, list + detail.
- Status badges for sandbox, deployment, compute, billing, and security states.
- Drawers and dialogs for contained workflows.
- Command palette and Ask OSA controls.
- File tree, terminal, preview iframe, usage summary, and deployment panels.

## Remove Or Merge

- Duplicate button families that only differ visually.
- Decorative card variants with no product role.
- Repeated chat/input shells that should become one canonical agent composer.
- Demo-only modules that do not map to MIOSA product workflows.
- Any component that requires a special color, radius, or font rule by itself.

## Component Quality Bar

Each kept component needs:

- A real product role.
- A stable API.
- Keyboard/focus behavior where relevant.
- Loading, empty, error, disabled, and selected states.
- A single source of styling truth.
- No hidden dependency on app-only stores unless wrapped behind local adapters.

## Component Cleanup Checklist

Use this checklist when deciding what stays in the Foundation library.

| Decision | Keep When | Remove Or Merge When |
|---|---|---|
| Button variant | It maps to a real action hierarchy | It only changes color, radius, or vibe |
| Card/panel | It represents a reusable product surface | It is a one-off demo wrapper |
| Input/composer | It handles real data entry or agent prompts | It duplicates another composer shell |
| Table/list | It supports scan, sort, compare, or operate workflows | It is only visual filler |
| Status badge | It encodes real state | It is decorative labeling |
| Module page | It maps to a MIOSA product workflow | It is a generic SaaS mockup |

# Computer use

Source: src/routes/docs/computer-use/+page.md
Description: Let software operate a real Linux desktop on a MIOSA Computer - screenshots, mouse, keyboard, windows, accessibility, and a live viewer a human can take over.

# Computer use

A [Computer](/docs/computers/overview/) is a durable cloud desktop: a full Linux GUI streamed live from a MIOSA microVM.
**Computer use** is the perception-action loop that lets software operate that desktop the way a person would: look at the screen, decide, take one action, look again.

Use it when the task depends on pixels, a logged-in browser session, desktop apps, the accessibility tree, or a human taking over the same machine an agent was using.
For code execution and builds, use a [Sandbox](/docs/develop/sandboxes/) instead.
If you only need a browser, [Browser use](/docs/browser-use/) runs inside a sandbox without a full desktop.

If the user or agent must see and operate a real screen, use a Computer.
If the workload only needs a shell, filesystem, process, or preview port, use a Sandbox.
If it only needs a browser, use [Browser use](/docs/browser-use/).

## What a Computer gives you


    An Xfce desktop with Firefox and common Linux apps, streamed live and controllable through documented APIs.


    Screenshot, mouse, keyboard, scrolling, clipboard, window state, the accessibility tree, plus shell and files.


    A signed-in operator opens the same running desktop, watches, and takes over from where automation stopped.


    Agent harnesses and MCP clients drive the same desktop through the same control APIs and the same viewer.


## Control surfaces

Computer use is reachable from the Python SDK, TypeScript SDK, CLI, MCP tools, REST API, and the live viewer.
Pick the surface that matches the caller.

| Caller | Use | Example |
|---|---|---|
| Python agent | Python SDK | `computer.screenshot()` |
| Node app | TypeScript SDK | `await computer.leftClick(500, 500)` |
| Terminal operator | CLI | `miosa api GET /computers/cmp_123/desktop/screenshot > screen.png` |
| MCP agent | MCP tools | `computer_screenshot`, then `computer_click` |
| Custom backend | REST API | `POST /api/v1/computers/{id}/desktop/click` |
| Human operator | Live viewer | Open the Computer desktop and take control |

Capture a screenshot or read the accessibility tree first.
Decide from the observed state, perform one action, then capture again before the next action.
That keeps the agent grounded in the real desktop instead of assuming the UI changed.

## The perception-action loop

Diagram:
sequenceDiagram
    participant A as Agent / SDK
    participant API as Computer API
    participant X as X11 desktop

    A->>API: screenshot()
    API->>X: read screen
    X-->>API: pixels
    API-->>A: PNG

    A->>A: decide the next action
    A->>API: left_click(500, 300)
    API->>X: inject click
    X-->>API: ok
    API-->>A: ack

    A->>API: screenshot()
    API-->>A: PNG

Perceive, decide, act once, perceive again.
Every action is a synchronous, authenticated request against a running Computer.

## Live viewer

A Computer desktop is also a live pixel stream that a browser can render.
The platform workspace shows it behind a **desktop** button; your own app can embed the same stream with a short-lived URL minted on your backend.

- Platform desktop button: signed-in MIOSA users, normal session permissions.
- Embedded stream URL: your backend mints a short-lived desktop URL with the MIOSA API key.
- Raw external desktop link: direct viewer access, gated by a viewer password.

The operator sees the same machine the agent was using, can watch, and can take over input.
See [Embedding & streaming](/docs/computers/embedding/) for the iframe and token flow.

Mint stream URLs on your backend.
Send only the short-lived URL to the browser.
Never put a MIOSA API key in frontend code.

## Agent harness usage

An agent harness drives a Computer the same way any other client does: it calls the control APIs in a loop, and it can run headless or behind the live viewer.

| Harness entry point | What it does |
|---|---|
| MCP tools | `computer_screenshot`, `computer_click`, `computer_type`, `computer_key`, `computer_scroll`, and the rest of the desktop tools, in one model loop. |
| CLI | `miosa computer` covers create, start, screenshot, click, type, key, a11y tree, and exec. |
| SDK with a computer-use toolset | The Python and TypeScript SDKs ship a computer-use toolset that maps a model's actions onto the desktop methods. |
| In-VM agent (OSA) | Optional, disabled by default; activate it to run multi-step desktop tasks inside the Computer itself. |

Because the viewer and the harness share one machine, an operator can open the live desktop mid-run, observe, and take over without moving any state.

## Access model

| Access path | Who uses it | Authentication |
|---|---|---|
| Platform desktop button | Signed-in MIOSA users | Normal MIOSA session and workspace permissions |
| Embedded stream URL | Your app backend and frontend | Your backend mints a short-lived URL with the MIOSA API key |
| Raw external desktop link | Emergency or direct viewer access | Viewer password gate |

Authenticated platform links and stream URLs do not need the raw viewer password.
Use `viewer_password()` / `rotate_viewer_password()` only for raw external viewer links.

# Computer use API reference

URL: https://miosa.ai/docs/computer-use/api-reference
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computer-use/api-reference
Source: src/routes/docs/computer-use/api-reference/+page.md
Description: Every MIOSA Computer desktop control endpoint - screenshot, mouse, keyboard, scroll, clipboard, windows, accessibility tree, and the one-shot window-state read.

# API reference

Desktop control endpoints proxy authenticated commands to the agent inside the Computer.
All of them require the Computer to be `running`; a stopped or provisioning Computer returns `409 COMPUTER_NOT_RUNNING`.

Base path: `/api/v1/computers/{id}/desktop`.

Full surface is on `api.miosa.ai`.
The narrower developer host `sandboxes.miosa.ai` exposes the read and common-action endpoints only: screenshot, screenshot/region, click, type, key, scroll, drag, double-click, wait, windows, cursor, screen-size, accessibility-tree, window/focus, launch, and window-state.
The low-level endpoints listed below - hotkey, key-down/key-up, mouse-down/mouse-up, move, clipboard, wallpaper, environment, and per-window geometry - are on `api.miosa.ai`.

## Observation

| Method | Path | Purpose |
|---|---|---|
| `GET` | `/screenshot` | Full desktop as PNG (`Content-Type: image/png`) |
| `POST` | `/screenshot/region` | Rectangular region as PNG; body `{ x, y, width, height }` |
| `GET` | `/windows` | Open windows: `id`, `title`, `class`, `x`, `y`, `width`, `height`, `focused` |
| `GET` | `/cursor` | Cursor position `{ x, y }` in screen pixels |
| `GET` | `/screen-size` | Display resolution `{ width, height }` |
| `GET` | `/environment` | Desktop environment name and version (for example `xfce4`) |
| `GET` | `/accessibility-tree` | AT-SPI element tree as nested JSON |
| `GET` | `/window-state` | Screenshot **and** accessibility tree in one round trip |

### `GET /desktop/window-state`

Runs the screenshot and the accessibility tree in parallel and returns them together from the same moment, so an agent pays one round trip instead of two.

```json
{
  "data": {
    "screenshot": {
      "content_type": "image/png",
      "encoding": "base64",
      "bytes": 214733,
      "data": "iVBORw0KGgo..."
    },
    "accessibility_tree": { "role": "frame", "name": "Firefox", "children": [ ] },
    "captured_at": "2026-10-10T12:00:00.000000Z"
  }
}
```

A part that fails does not fail the request: it is `null` and named under an `errors` object, so the caller can still use the other half.
Only when both parts fail is the request a `502 AGENT_UNAVAILABLE`.

## Mouse

| Method | Path | Body |
|---|---|---|
| `POST` | `/click` | `x`, `y`, `button` (`left`\|`right`\|`middle`, default `left`) |
| `POST` | `/double-click` | `x`, `y` |
| `POST` | `/move` | `x`, `y` (move the pointer, no click) |
| `POST` | `/drag` | `from_x`, `from_y`, `to_x`, `to_y` |
| `POST` | `/mouse-down` | `x`, `y`, `button` (default `left`) |
| `POST` | `/mouse-up` | `x`, `y`, `button` (default `left`) |
| `POST` | `/scroll` | `x`, `y`, `direction` (`up`\|`down`\|`left`\|`right`), `clicks` |

The public endpoints are `/desktop/mouse-down` and `/desktop/mouse-up`.
Inside the Computer they map to the lower-level actions named `mouse-press` and `mouse-release`.
The names differ between the public contract and the on-machine action; the pair-and-release behavior is the same.
For a one-shot click, use `POST /desktop/click` - do not assume the request field is named `press`.

`mouse-down` / `mouse-up` hold and release a button with no click between them, so you can move the pointer mid-drag (`move` then `mouse-up`) or implement a long press.

## Keyboard

| Method | Path | Body |
|---|---|---|
| `POST` | `/type` | `text`, optional `delay` (ms between keys) |
| `POST` | `/key` | `key` - a single key or a `+` chord, for example `Return` or `ctrl+a` |
| `POST` | `/hotkey` | `keys` - a simultaneous combo, for example `["ctrl", "shift", "t"]` |
| `POST` | `/key-down` | `key` - press and hold |
| `POST` | `/key-up` | `key` - release |

Key names follow the X11 keysym convention: `Return`, `Tab`, `BackSpace`, `Delete`, `Home`, `End`, `Page_Up`, `Page_Down`, `Up`, `Down`, `Left`, `Right`, `F1`-`F12`, and the modifiers `super`, `ctrl`, `alt`, `shift`.
`type` types literal text and does not interpret key names; use `key` for those.

## Clipboard, windows, and desktop

| Method | Path | Body |
|---|---|---|
| `GET` | `/clipboard` | Read clipboard text |
| `POST` | `/clipboard` | `text` - write clipboard text |
| `POST` | `/window/focus` | `window_id` |
| `POST` | `/launch` | `command` - launch an app, runs in the background |
| `GET` | `/window/{window_id}/size` | Read a window's `{ width, height }` |
| `GET` | `/window/{window_id}/position` | Read a window's `{ x, y }` |
| `POST` | `/window/{window_id}/resize` | `width`, `height` |
| `POST` | `/window/{window_id}/move` | `x`, `y` |
| `POST` | `/window/{window_id}/maximize` | - |
| `POST` | `/window/{window_id}/minimize` | - |
| `POST` | `/window/{window_id}/close` | - |
| `POST` | `/wallpaper` | `path` - set the background from a file inside the VM |

## Timing

| Method | Path | Body |
|---|---|---|
| `POST` | `/wait` | `seconds` - sleep inside the Computer, capped at 30, to let UI animations settle |

## Related endpoints

| Method | Path | Purpose |
|---|---|---|
| `GET` | `/api/v1/computers/{id}/screenshot` | Alias for the full-desktop screenshot |
| `GET` | `/api/v1/computers/{id}/urls` | Signed desktop, VNC, terminal, and entry URLs |
| `POST` | `/api/v1/computers/{id}/stream-token` | Mint a short-lived viewer stream token |
| `GET` | `/api/v1/computers/{id}/vnc-credentials` | VNC credentials for the desktop |
| `GET` | `/api/v1/computers/{id}/viewer-password` | Read the raw external viewer password |
| `POST` | `/api/v1/computers/{id}/viewer-password/rotate` | Rotate the raw external viewer password |

## Coordinates

Coordinates are screen pixels with the origin at the top-left, matching what `screen-size` and `cursor` report.
A vision model may be shown a scaled-down screenshot; map its output back to screen pixels before sending an action.

## Errors

| Status | Code | Cause |
|---|---|---|
| `409` | `COMPUTER_NOT_RUNNING` | The Computer is stopped, provisioning, or recovering |
| `502` | `AGENT_UNAVAILABLE` | The agent inside the Computer did not answer |
| `429` | - | Rate limited; honor `X-RateLimit-*` and `Retry-After` |

# Computer use limits

URL: https://miosa.ai/docs/computer-use/limits
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computer-use/limits
Source: src/routes/docs/computer-use/limits/+page.md
Description: Latency, coordinate space, sizing, authentication, and rate limits for MIOSA Computer desktop control.

# Limits

## Latency

Desktop methods run synchronously over authenticated HTTP RPC. Typical round-trip from the MIOSA edge:

| Method type | Typical latency |
|---|---|
| Click, key, scroll, type | 30-80 ms |
| Screenshot | 100-300 ms (compression-bound) |
| Window list | 50-100 ms |
| `bash()` / `python()` | 50 ms plus command execution time |

For high-frequency loops, prefer `bash()` for multi-step operations over many individual GUI calls.
`GET /desktop/window-state` returns the screenshot and the accessibility tree together, so perception costs one round trip instead of two.

## Coordinate space

Coordinates are screen pixels with the origin at the top-left, matching what `GET /desktop/screen-size` and `GET /desktop/cursor` report.
A vision model may be shown a scaled-down screenshot; map its output back to screen pixels before sending an action.

## Screenshots

Screenshots are PNG.
A full desktop image is typically a few hundred kilobytes; regions are smaller.
Use `/desktop/screenshot/region` when only part of the screen matters, and `window-state` when you need pixels and structure at once.

## Sizing

| Size | vCPU | RAM | Disk | Typical use |
|---|---|---|---|---|
| `xs` | 1 | 2 GB | 10 GB | Lightweight headless tasks |
| `small` | 2 | 4 GB | 20 GB | **Default** for a single agent and basic browsing |
| `medium` | 4 | 8 GB | 40 GB | Heavier desktop apps, faster page loads |
| `large` | 8 | 16 GB | 80 GB | Multi-app, large-context workloads |
| `xl` | 16 | 32 GB | 160 GB | Intensive parallelism |

GPU support for accelerated desktop and GPU-aware workflows is plan-dependent.

## Lifecycle

Stopping a Computer pauses compute and preserves the filesystem and browser profile.
Restarting resumes from that state.
Desktop endpoints only accept requests while the Computer is `running`; otherwise they return `409 COMPUTER_NOT_RUNNING`.

## Authentication

Desktop methods require the same workspace API key as every other MIOSA resource.
Call them server-side.
For browser-side control, mint a scoped token instead of shipping the API key - see [Embedding & streaming](/docs/computers/embedding/).

Mint stream URLs and scoped tokens on your backend.
Send only the short-lived URL or token to the browser.

## Rate limits

Rate limits vary by key, tenant policy, and endpoint family.
Honor `X-RateLimit-*` and `Retry-After` response headers.
Individual desktop actions are fast, but a tight perceive-act loop still issues many requests; batch where the work does not need pixels.

## Errors

| Status | Code | Cause |
|---|---|---|
| `409` | `COMPUTER_NOT_RUNNING` | The Computer is stopped, provisioning, or recovering |
| `502` | `AGENT_UNAVAILABLE` | The agent inside the Computer did not answer |
| `429` | - | Rate limited |

# Computer use quickstart

URL: https://miosa.ai/docs/computer-use/quickstart
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computer-use/quickstart
Source: src/routes/docs/computer-use/quickstart/+page.md
Description: Create a MIOSA Computer, run the first screenshot-act-verify loop, and watch the live desktop a human can take over.

# Quickstart

Create a Computer, take a screenshot, act once, and screenshot again.
This is the loop every computer-use agent runs, whether it is headless or watched by a person.

## 1. Create and start a Computer

```python

client = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])

computer = client.computers.create(name="agent-1", template_type="miosa-desktop", size="small")
computer.start()
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const computer = await miosa.computers.create({
  name: "agent-1",
  template_type: "miosa-desktop",
  size: "small",
})
await computer.start()
```

`start()` returns once the desktop is running and accepting actions.
Computer state is `provisioning`, `running`, `stopped`, `recovering`, `error`, or `deleted`.

## 2. The first loop

Capture, decide, act once, capture again.
Do not issue several blind actions in a row.

```python
png = computer.screenshot()

# Decide from the screenshot, or read the accessibility tree for structured elements.
tree = computer.get_accessibility_tree()

computer.left_click(640, 480)
after = computer.screenshot()   # verify the UI changed
```

```typescript
const png = await computer.screenshot()

const tree = await computer.desktop.accessibilityTree()

await computer.leftClick(640, 480)
const after = await computer.screenshot()
```

```bash
curl https://api.miosa.ai/api/v1/computers/$CID/desktop/screenshot \
  -H "Authorization: Bearer $MIOSA_API_KEY" --output before.png

curl -X POST https://api.miosa.ai/api/v1/computers/$CID/desktop/click \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"x": 640, "y": 480, "button": "left"}'
```

Coordinates are screen pixels with the origin at the top-left.
Read the current resolution with `get_screen_size()` if you need to scale a model's output.

A loop that screenshots after every action is slower per step but far more reliable than a batch of guessed actions.
For multi-step shell work that does not need pixels, prefer `bash()` over a long chain of GUI calls.

## 3. Watch it live

The same running desktop can be shown to a browser.
On the platform, open the Computer and use the desktop button.
In your own app, mint a short-lived stream URL on your backend and embed it.

```python
urls = computer.urls()
print(urls["desktop_url"])   # pass this to your frontend, never your API key
```

```typescript
const urls = await computer.urls()
// <iframe src={urls.desktop_url} sandbox="allow-same-origin allow-scripts" />
```

See [Embedding & streaming](/docs/computers/embedding/) for the token flow, iframe policy, and expiry handling.

## 4. A full agent loop

```python

from miosa import Miosa

miosa_client  = Miosa(api_key=os.environ["MIOSA_API_KEY"])
claude_client = anthropic.Anthropic()

computer = miosa_client.computers.create(name="browser-agent", template_type="miosa-desktop", size="small")
computer.start()
computer.launch("firefox")

for _ in range(10):
    b64 = computer.screenshot_base64()

    response = claude_client.messages.create(
        model="claude-opus-4-5",
        max_tokens=1024,
        messages=[{
            "role": "user",
            "content": [
                {"type": "image", "source": {"type": "base64", "media_type": "image/png", "data": b64}},
                {"type": "text", "text": "Navigate to miosa.ai and screenshot the homepage."},
            ],
        }],
    )

    # Parse an action from the model output, then act once.
    text = response.content[0].text
    if "left_click" in text:
        computer.left_click(500, 500)
    elif "type" in text:
        computer.type("https://miosa.ai\n")

computer.stop()
```

tree = computer.get_accessibility_tree()

computer.left_click(500, 500)
after = computer.screenshot()
```

```typescript
const png = await computer.screenshot()
const tree = await computer.desktop.accessibilityTree()

await computer.leftClick(500, 500)
const after = await computer.screenshot()
```

## Feed a screenshot to a vision model

`Screenshot_base64` returns a string you can pass straight through as image data.

```python
b64 = computer.screenshot_base64()

client = anthropic.Anthropic()
response = client.messages.create(
    model="claude-opus-4-5",
    max_tokens=1024,
    messages=[{
        "role": "user",
        "content": [
            {"type": "image", "source": {"type": "base64", "media_type": "image/png", "data": b64}},
            {"type": "text", "text": "What is on screen, and where should I click?"},
        ],
    }],
)
```

## Keyboard and mouse

```python
computer.type("hello, world")     # literal text
computer.key("Return")            # one key
computer.key("ctrl+a")            # a chord
computer.hotkey("ctrl", "shift", "t")

computer.key_down("shift")
computer.left_click(800, 200)     # shift-click to extend a selection
computer.key_up("shift")

computer.mouse_down(200, 200)
computer.move_cursor(400, 400)    # move while held
computer.mouse_up(400, 400)
```

```typescript
await computer.type("hello, world")
await computer.key("Return")
await computer.desktop.hotkey("ctrl", "shift", "t")

await computer.desktop.keyDown("shift")
await computer.leftClick(800, 200)
await computer.desktop.keyUp("shift")

await computer.desktop.mouseDown(200, 200)
await computer.desktop.moveMouse(400, 400)
await computer.desktop.mouseUp(400, 400)
```

## Clipboard, scroll, and windows

```python
computer.set_clipboard("text to paste")
computer.hotkey("ctrl", "v")

computer.scroll("down", clicks=3)
computer.scroll_up(clicks=5)

w = computer.windows()[0]
computer.focus_window(w["id"])
computer.set_window_size(w["id"], 1280, 800)
computer.set_window_position(w["id"], 100, 50)
computer.maximize_window(w["id"])
```

```typescript
await computer.desktop.setClipboard("text to paste")
await computer.desktop.hotkey("ctrl", "v")

await computer.scroll("down", 3)

const w = (await computer.windows())[0]
await computer.focusWindow(w.id)
await computer.desktop.resizeWindow(w.id, 1280, 800)
await computer.desktop.moveWindow(w.id, 100, 50)
await computer.desktop.maximizeWindow(w.id)
```

## Shell, Python, and files

These run inside the VM with no GUI interaction and are usually the fastest way to do multi-step work.

```python
print(computer.bash("ls /workspace/Desktop"))
print(computer.python("print(1 + 1)"))

computer.write_file("/workspace/script.py", "print('hello')")
computer.bash("python3 /workspace/script.py")
print(computer.read_file("/workspace/.bashrc"))
```

## CLI

```bash
miosa api GET "/computers/$COMPUTER_ID/desktop/screenshot" > before.png
miosa api GET "/computers/$COMPUTER_ID/desktop/accessibility-tree"
miosa api POST "/computers/$COMPUTER_ID/desktop/click" -d '{"x": 500, "y": 500}'
miosa api GET "/computers/$COMPUTER_ID/desktop/screenshot" > after.png
```

# Computer use vs browser use: which to pick

URL: https://miosa.ai/docs/computer-use/vs-browser-use
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computer-use/vs-browser-use
Source: src/routes/docs/computer-use/vs-browser-use/+page.md
Description: A short comparison of MIOSA browser use inside a sandbox and full computer use on a durable desktop, to pick the right one for a task.

# Computer use vs browser use: which to pick

Both drive a real browser. They differ in how much machine you rent.

If the task is a web page an agent or a person should watch, use [Browser use](/docs/browser-use/) - it runs in any sandbox and bills as ordinary sandbox usage.
If the task needs a full desktop, other apps, or takeover of the whole screen, use [Computer use](/docs/computer-use/).

| | Browser use | Computer use |
|---|---|---|
| What runs | A live browser inside a sandbox | A full Linux desktop on a Computer |
| Where | Any sandbox, any template | A Computer you create and start |
| Setup | On by default; nothing to choose at create time | Create a Computer, then start it |
| Live viewer | On the Sandbox page: take control, view-only share links, full screen | A streamable desktop, embeddable with a short-lived URL |
| Agent access | Over CDP - Playwright, Puppeteer | Screenshot and control APIs: mouse, keyboard, windows, accessibility |
| Human takeover | The browser view | The whole desktop |
| Other apps | No - browser only | Yes - any installed Linux app |
| Persistence | Survives pause and resume | Survives stop and start |
| Billing | Plain sandbox usage | Computer compute while running |
| Best for | Web automation, scraping, logged-in browser work that should be watched | GUI apps, desktop workflows, screenshot QA, full human handoff |

## Pick browser use when

- The task lives entirely on web pages.
- You want the cheapest isolated environment: a sandbox you already use for code.
- A person should be able to watch, take control, or share a view-only link.
- Playwright or Puppeteer is your driver.

## Pick computer use when

- The task needs desktop apps, file pickers, extensions, or multiple windows.
- The agent works from pixels and the accessibility tree across the whole screen.
- A human must take over the exact machine an agent was using.
- You need a durable desktop that keeps its browser profile and installed tools across restarts.

## Next

- [Browser use](/docs/browser-use/) - start a live browser in any sandbox.
- [Computer use](/docs/computer-use/) - the desktop perception-action loop.

# Inside a Computer

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computers/anatomy
Source: src/routes/docs/computers/anatomy/+page.md
Description: What ships in a Computer and how the desktop, persistent disk, stream gateway, and control API fit together.

# Inside a Computer

## What is in the box

- **Xfce desktop** with Firefox and common Linux apps pre-installed.
- **Terminal** with `bash`, `python`, and a standard CLI toolchain.
- **Persistent storage** so files and browser state survive stop/start cycles through snapshot restore.
- **Desktop streaming** so the platform or your app can embed the live screen with short-lived tickets.
- **Desktop control API** for screenshots, clicks, typing, scrolling, clipboard, windows, accessibility, shell, and files.
- **OSA agent** pre-installed and disabled by default.
  Activate it when you want autonomous desktop task execution.

## What a Computer is, concretely

| Layer | What it gives you |
|---|---|
| Desktop VM | A real Linux graphical session with browser, files, packages, and user state |
| Persistent disk | Durable filesystem and browser profile across stop/start cycles |
| Stream gateway | Live desktop pixels and input forwarding for platform UI or embedded apps |
| Control API | Screenshots, clicks, typing, scrolling, clipboard, shell, files, windows, and accessibility |
| Workspace attribution | Tenant, workspace, user, metadata, and billing ownership attached to the machine |
| Human takeover | A signed-in operator can open the same running desktop an agent was using |

Computers are not disposable command runners.
They are long-lived desktop machines that can be resumed, inspected, embedded, and controlled.

## How it fits together

Diagram:

    SDK["Python / TypeScript SDK"] -->|REST| API["MIOSA API"]
    API --> Desktop["Desktop environment"]
    Desktop -->|input| Session["Desktop session"]
    Desktop -->|frame| Stream["Pixel stream"]
    Stream -->|WebSocket| Browser["Browser iframe"]

Your code talks to the MIOSA API.
MIOSA routes actions to a desktop command service.
The command service drives the X11 session and returns screenshots or action confirmations.
For embedded views, MIOSA streams the desktop over WebSocket to a browser iframe.

# Embedding & Streaming

URL: https://miosa.ai/docs/computers/embedding
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computers/embedding
Source: src/routes/docs/computers/embedding/+page.md
Description: Embed a live Computer desktop in your own UI with a short-lived stream URL. Pixel streaming and input forwarding are handled by MIOSA.

To show a live desktop session in your end-user's browser, embed MIOSA's desktop stream.
Use this for "watch the AI work" UI, manual takeover, internal support tools, and kiosk-style apps.

## Access model

There are three ways to enter a Computer desktop.
They are intentionally different because they protect different surfaces.

| Access path | Who uses it | Authentication |
|---|---|---|
| Platform desktop button | Signed-in MIOSA users | Normal MIOSA session and workspace permissions |
| Embedded stream ticket | Your app backend and frontend | Your backend mints a short-lived URL with the MIOSA API key |
| Raw external desktop URL | Emergency or direct viewer access | Viewer password gate |

Use embedding for your own UI.
Use `viewer_password()` / `rotate_viewer_password()` only for raw external desktop viewer links.
Authenticated platform desktop links and stream tickets do not need the raw viewer password.

Mint stream tickets on your backend.
Send only the short-lived stream URL to the browser.
Never put a MIOSA API key in frontend code.

## Quick example

```python

client = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])

# Create and start a desktop computer
computer = client.computers.create(name="agent-1", template_type="miosa-desktop", size="small")
computer.start()

# Capture the screen, interact with it
png_bytes = computer.screenshot()
computer.left_click(640, 480)
computer.double_click(100, 200)
computer.type("hello world")
computer.key("Return")
computer.scroll("down", clicks=3)
computer.hotkey("ctrl", "c")
computer.bash("firefox &")
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

// Create and start a desktop computer
const computer = await miosa.computers.create({
  name: "agent-1",
  template_type: "miosa-desktop",
  size: "small",
})
await computer.start()

// Capture the screen, interact with it
const png = await computer.screenshot()
await computer.leftClick(640, 480)
await computer.doubleClick(100, 200)
await computer.type("hello world")
await computer.key("Return")
await computer.scroll("down", 3)
await computer.hotkey("ctrl", "c")
await computer.bash("firefox &")
```

## The flow
```

1. Your backend asks MIOSA for signed Computer URLs or a stream token for a running computer
2. MIOSA returns a short-lived desktop URL or token
3. Your frontend renders an iframe with that URL
4. The user sees the live desktop; keyboard/mouse input is forwarded into the VM
```

## Operator workflow

Most production Computer flows look like this:

Diagram:
sequenceDiagram
    participant User as User or Agent
    participant App as Your App
    participant API as MIOSA API
    participant VM as Computer VM
    participant Stream as Stream Gateway

    User->>App: Start desktop task
    App->>API: Create or resume Computer
    API->>VM: Boot desktop and agent services
    App->>API: Mint stream ticket
    API-->>App: Short-lived stream URL
    App-->>User: Embedded desktop iframe
    User->>Stream: Clicks, keys, clipboard
    Stream->>VM: Forward input
    VM-->>Stream: Pixels
    Stream-->>User: Live desktop

The Computer is the stateful machine.
The stream ticket is only temporary access to that machine.
If the browser tab closes, the Computer keeps its state until you stop or delete it.

## Get an embed URL

```typescript
const urls = await computer.urls()
console.log(urls.desktop_url)
console.log(urls.expires_at)
```

```python
urls = computer.urls()
print(urls["desktop_url"])
print(urls["expires_at"])
```

```bash
curl https://api.miosa.ai/api/v1/computers/$CID/urls \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Response:
```json
{
  "desktop_url": "https://agent-1.computer.miosa.ai/desktop/index.html?auth=...",
  "desktop_entry_url": "https://agent-1.computer.miosa.ai/desktop/index.html",
  "vnc_url": "https://agent-1.computer.miosa.ai/desktop/index.html?auth=...",
  "ws_url": "wss://agent-1.computer.miosa.ai/vnc/websockify?auth=...",
  "terminal_url": "wss://agent-1.computer.miosa.ai/ws/terminal/cmp_xxx",
  "token": "miosa_stream_...",
  "expires_at": 1783000000,
  "computer_id": "cmp_xxx"
}
```

`desktop_url` is what you embed.
`token` is returned in case you need to construct your own stream URL or proxy the stream through a custom gateway.

## Embed

```jsx
<iframe
  src={streamUrl}
  sandbox="allow-same-origin allow-scripts allow-forms"
  className="w-full h-[600px] border-0 rounded-lg"
  allow="clipboard-read; clipboard-write"
/>
```

```html
<iframe
  src="https://agent-1.computer.miosa.ai/desktop/index.html?auth=..."
  sandbox="allow-same-origin allow-scripts allow-forms"
  style="width:100%; height:600px; border:0;"
  allow="clipboard-read; clipboard-write">
</iframe>
```

MIOSA handles pixel streaming and input forwarding inside the iframe. The user clicks or types in the iframe and those events go to the desktop.

## What's streamed

- **Pixels**  -  encoded video tuned for desktop content.
- **Cursor position**  -  overlay rendered client-side.
- **Audio**  -  optional, off by default. Pass `?audio=1` if your app needs it.
- **Clipboard**  -  bidirectional, gated by the iframe's `allow="clipboard-read; clipboard-write"`.

## Read-only mode

For "user watches the agent" UI where the end-user shouldn't interact with the desktop:

Use your own application permissions to decide whether to render an interactive iframe or a watch-only surface.
Public read-only stream token controls are plan-dependent and should not be assumed unless enabled for your tenant.

## Bandwidth

Default codec / bitrate is tuned for typical desktop content, usually about 500 Kbps to 2 Mbps.
For high-motion content, such as video playback inside the VM, the codec adapts but expect higher bitrate.
The stream gateway is geo-routed to the user's nearest region for lower latency.

## Lifetime

Stream URLs are short-lived.
The default lifetime is 1 hour, and max lifetime is plan-dependent.
When a token expires, the stream disconnects.
Your frontend should watch `expires_at` and re-mint before that.

Multiple stream URLs per computer are fine.
Multiple browsers can watch the same desktop simultaneously.
They all see the same pixels.

## Custom domains / branded streaming

White-label customers can configure a branded stream domain so end users see your brand in the iframe URL.
The DNS and TLS flow follows the same contract as [Deployment Domains](/docs/docker-host/domains/), with a different routing target.
Contact support to set up branded streaming.

## White-label desktops

Computers support per-tenant desktop branding. After starting a computer, push a wallpaper and apply it with two SDK calls. The wallpaper persists across stop/start cycles because it is stored in the VM's snapshotted filesystem.

```python

client   = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])
computer = client.computers.create(
    name="acme-agent",
    template_type="miosa-desktop",
    size="small",
    external_workspace_id="acme-corp",
)
computer.start()

# Push the tenant wallpaper from your server's filesystem
computer.write_file("/tmp/acme-wallpaper.png", open("assets/acme-bg.png", "rb").read())
computer.set_wallpaper("/tmp/acme-wallpaper.png")

# Optionally verify the DE
de = computer.get_desktop_environment()
print(de)   # {"name": "xfce4", "version": "4.18"}
```

```typescript

const miosa    = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })
const computer = await miosa.computers.create({
  name: "acme-agent",
  template_type: "miosa-desktop",
  size: "small",
  externalWorkspaceId: "acme-corp",
})
await computer.start()

// Push and apply the tenant wallpaper
const bg = fs.readFileSync("assets/acme-bg.png")
await computer.writeFile("/tmp/acme-wallpaper.png", bg)
await computer.setWallpaper("/tmp/acme-wallpaper.png")
```

For production deployments, bake the wallpaper directly into a custom template snapshot so every new computer boots with the correct branding.
No post-boot setup is required.
See the Templates documentation for details.

## CSP

The stream gateway emits `Content-Security-Policy` allowing the stream to be embedded from approved origins:

- Default: `*.miosa.app`, `*.miosa.ai`, `localhost:4000`.
- For white-label: add your platform origin via tenant config.

If your iframe doesn't render, check the parent page's CSP isn't blocking the iframe and that the stream gateway CSP includes your origin.

## Audit

Each stream URL issuance emits an audit event with:

- The computer ID
- The token prefix
- Issuing API key
- External attribution

If a token is leaked, rotate the user session or stop the Computer while you investigate.
Stream tokens are short-lived by default.

# Fast start & readiness

URL: https://miosa.ai/docs/computers/fast-start
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/computers/fast-start
Source: src/routes/docs/computers/fast-start/+page.md
Description: How MIOSA starts managed desktop Computers quickly, defines browser readiness, and exposes failures without false Live states.

# Fast start & readiness

MIOSA Computers use ready capacity on the managed fleet so a new desktop can be assigned without waiting for a full cold boot.
The product target is simple: click **Launch**, then receive an interactive desktop in about 800 to 900 ms on the warm path.

## Verified result

The production canary measured on 2026-08-06 completed **10 of 10** launches and reached a browser-ready desktop in a median **740 ms**.

| Phase | Time |
|---|---:|
| Successful launches | `10 / 10` |
| Create response median | `348 ms` |
| Create request to browser-ready desktop median | **`740 ms`** |
| Create request to browser-ready desktop p90 | **`809 ms`** |
| Slowest sample | `942 ms` |

Every canary used the warm path and did not require the restart fallback.
The browser used the bundled direct noVNC client, and `Live` required its real RFB connection event.
The launch path warmed the future viewer transport concurrently with the create request and retained bounded retry for route-registration races.

The 10-sample result is a dated production canary, not a universal latency guarantee.
Region, fleet capacity, network latency, image choice, and cold-path fallback can change startup time.

## What browser-ready means

MIOSA does not call a Computer ready merely because its database record exists or its lifecycle says `Running`.
Browser readiness requires the complete viewing path to work.

1. The create request claims ready desktop capacity.
2. The stream API returns a short-lived authenticated viewer URL.
3. The bundled viewer client connects directly to the authenticated VNC WebSocket.
4. The VNC WebSocket upgrades with the stream token.
5. The browser renders a usable desktop frame.
6. Opening the Computer workspace keeps the desktop mounted and connects its terminal.

The managed fleet keeps separate reserves on every host: 20 ready desktop slots and 20 ready sandbox slots.
Desktop slots enter the ready pool only after the default MIOSA wallpaper is visible.
Tenant wallpaper and desktop branding are applied during claim, before the Computer is handed to the user.


    A browser error document or failed iframe navigation must not be labeled as a live desktop.


    The stream URL is short-lived and scoped to the selected Computer.


    The gallery-to-workspace transition preserves the viewer handoff instead of requesting a conflicting session.


## Application integration

Request the Computer stream URL from your backend and pass only the short-lived URL to the browser.
Embed the authenticated viewer URL returned by the API instead of rebuilding the desktop URL from the Computer slug.

Your UI should represent these states separately:

| State | Meaning | Recommended UI |
|---|---|---|
| `provisioning` | Capacity is being assigned or the guest is becoming ready | Show bounded progress |
| `running` with viewer ready | Desktop and stream path are usable | Show `Live` and reveal the viewer |
| `paused` | Durable state exists but the active desktop is stopped | Offer Resume |
| viewer unavailable | Lifecycle and viewer reachability disagree | Show an actionable error and retry control |
| failed | Provisioning or startup failed | Show the backend error and recovery action |

Do not promote an iframe to `Live` from its generic `load` event alone.
Browsers also fire that event for their own network-error documents.

## Troubleshooting

### The card says Running but the viewer says Host unavailable

Treat viewer reachability as authoritative for the user-visible state.
Refresh the Computer lifecycle, then retry the stream request.
If the mismatch persists, contact support with the Computer ID, region, and approximate creation time.

### The viewer page returns 503

The public viewer gateway cannot reach the active compute proxy or assigned host.
This is a platform routing failure rather than proof that your files or Computer record were lost.
Retry once, then contact support if it persists.

### The stream request returns 409

The Computer is not currently in a streamable lifecycle state.
Refresh its status and resume it when the API reports `paused`.
Do not retry indefinitely without re-reading the lifecycle.

### The iframe loads but no desktop appears

Confirm that you embedded the authenticated viewer URL returned by the API.
Do not substitute a raw desktop entry URL or wait for an undocumented cross-frame event.

Description: Computer fast startup, the desktop state machine, resource sizes, and workspace-scoped creation for per-tenant attribution.

# Lifecycle and sizing

A Computer is a long-lived machine. This page covers how fast it starts, the states it moves through, the sizes it runs on, and how to scope it to a workspace.

## Fast startup

MIOSA keeps ready desktop capacity on the managed fleet so a new Computer can be assigned instead of cold-booted from scratch.
The production acceptance test measures the complete user-visible path from creation to the first usable desktop frame.

The verified 2026-08-06 canary completed **10 of 10** warm launches and reached a browser-ready desktop in a median **740 ms**:

| Phase | Time |
|---|---:|
| Create response median | `348 ms` |
| Create request to browser-ready desktop median | **`740 ms`** |
| Create request to browser-ready desktop p90 | **`809 ms`** |
| Slowest sample | `942 ms` |

This is a dated warm-path canary, not a guarantee that every region and capacity condition will complete inside the sampled range.
See [Fast start & readiness](/docs/computers/fast-start/) for the readiness contract, measurement boundary, and troubleshooting guidance.

## Lifecycle

| State | Description |
|---|---|
| `provisioning` | The VM is being claimed, restored, and prepared |
| `running` | Desktop is up, streamable, and accepting API actions |
| `stopped` | Compute is stopped and filesystem state is preserved |
| `recovering` | MIOSA is restoring a desired-running Computer after host maintenance |
| `error` | Recovery did not complete; the preserved disk or snapshot remains available for retry |
| `deleted` | Permanent deletion; not reversible |

A stopped computer is not billed for compute; its disk is billed at $0.018 per GiB-month while it is stopped. Restarting resumes from the snapshot.

During host maintenance, MIOSA preserves Computer identity, disk state, snapshots, metadata, and desired state.
Computers that were running are restored and verified before the host returns to active service.
Intentionally stopped Computers remain stopped.

If a local resume fails, MIOSA preserves the disk and snapshot instead of replacing the Computer with a blank machine.
Use `delete` only when the state should be permanently removed.

## Sizing

| Size | vCPU | RAM | Disk | Typical use |
|---|---|---|---|---|
| `xs` | 1 | 2 GB | 10 GB | Lightweight headless tasks |
| `small` | 2 | 4 GB | 20 GB | **Default** for a single agent and basic browsing |
| `medium` | 4 | 8 GB | 50 GB | Heavier desktop apps, faster page loads |
| `large` | 8 | 16 GB | 100 GB | Multi-app, large-context AI workloads |
| `xl` | 16 | 32 GB | 200 GB | Intensive parallelism, large model weights |

GPU is not productized: the public API does not currently schedule GPU-backed desktops.

Computers ship with the OSA agent installed but disabled by default.
Activate it to give your computer a desktop AI assistant that can run multi-step desktop tasks autonomously.
OSA is controlled through documented MIOSA APIs.

## Workspace-scoped creation

Computers can be created inside a named workspace so that resources are isolated and billed separately. Pass `external_workspace_id` to attribute the computer to a tenant in your platform.

```python

client = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])

computer = client.computers.create(
    name="agent-1",
    template_type="miosa-desktop",
    size="small",
    external_workspace_id="acme-corp",      # your tenant identifier
    metadata={"agent_run": "run-2026-05-17"},
)
computer.start()
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const computer = await miosa.computers.create({
  name: "agent-1",
  template_type: "miosa-desktop",
  size: "small",
  externalWorkspaceId: "acme-corp",
  metadata: { agentRun: "run-2026-05-17" },
})
await computer.start()
```

`external_workspace_id` is a free-form string you control.
Use your own tenant, org, customer, or workspace identifier.
Usage is tracked per workspace in the billing dashboard so you can attribute compute costs to individual customers.

Source: src/routes/docs/computers/overview/+page.md
Description: Durable cloud desktops for browser agents, human takeover, GUI automation, and long-running computer-use workflows.

# Computers

A **Computer** is a durable cloud desktop.
It gives each user, agent, or workflow a real Linux GUI with browser state, files, shell access, desktop streaming, and programmatic control.
Use it when the work depends on pixels, sessions, browser logins, desktop apps, accessibility trees, or a human taking over the same machine an agent was using.

For pure code execution, builds, and preview servers, [Sandboxes](/docs/develop/sandboxes/) are cheaper and faster.
For a 24/7 production web app, use [Docker Host](/docs/docker-host/docker-deploy/).
Still deciding? See [Computers vs sandbox](/docs/computers/vs-sandbox/).

## 1. Create a Computer

```bash
miosa computer create --size small
miosa computer list
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const computer = await miosa.computers.create({
  name: "agent-1",
  template_type: "miosa-desktop",
  size: "small",
})
await computer.start()
```

```python

client = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])

computer = client.computers.create(
    name="agent-1",
    template_type="miosa-desktop",
    size="small",
)
computer.start()
```

Pass `external_workspace_id` to attribute the Computer to one of your tenants.
See [Lifecycle and sizing](/docs/computers/lifecycle/) for states, sizes, and workspace scoping.

## 2. Drive the desktop

```bash
miosa api GET /computers/cmp_123/desktop/screenshot > screen.png
```

```typescript
const png = await computer.screenshot()
await computer.leftClick(640, 480)
await computer.type("hello world")
await computer.key("Return")
await computer.bash("firefox &")
```

```python
png_bytes = computer.screenshot()
computer.left_click(640, 480)
computer.type("hello world")
computer.key("Return")
computer.bash("firefox &")
```

Start each loop with an observation, act once, then observe again.
The full action set is in [Computer use](/docs/computer-use/).

## 3. Watch it live

A Computer is also a live pixel stream.
Open it from the MIOSA console, or embed the same stream in your app with a short-lived URL minted on your backend.

```typescript
const urls = await computer.urls()
console.log(urls.desktop_url)
```

See [Embedding and streaming](/docs/computers/embedding/) for the token and iframe flow.

# Production checklist

Before you rely on a Computer in production, verify these points.

| Area | Check |
|---|---|
| Workspace attribution | Set `external_workspace_id`, `external_user_id`, or workspace/project fields when building a white-label app |
| Access | Use platform auth or stream tickets for normal users |
| Secrets | Put API keys in backend code or encrypted env, not inside frontend bundles |
| State | Use stop/start for durable sessions and delete only when state should be removed |
| Observability | Log the Computer ID, external IDs, and task/run ID together |
| Recovery | Design the app so a user can reopen the same running Computer after refreshing the browser |

Description: Choose a Computer or a Sandbox for a workload, with the rule of thumb and a side-by-side table.

# Computers vs sandbox

If the user or agent needs to see and operate a real screen, use a Computer.
If the workload only needs a shell, filesystem, process, or preview port, use a Sandbox.

## Pick by workload

| Workload | Pick | Why |
|---|---|---|
| Run tests, install packages, build code, expose a dev server | **Sandbox** | Faster and cheaper shell-first compute |
| Computer-use agent that must click through a website | **Computer** | Needs pixels, browser state, and input events |
| Logged-in browser session that must survive across tasks | **Computer** | Browser profile persists with the VM |
| Headless Playwright, API tests, CLI workflows | **Sandbox** | No visible desktop needed |
| Screenshot-based QA or visual inspection | **Computer** | Uses the rendered screen as truth |
| Desktop apps, extensions, file pickers, or manual takeover | **Computer** | Needs a full GUI and streamable session |
| Public 24/7 app URL for customers | **Docker Host** | Built for durable deployments and custom domains |

## What a Computer is for

| Use | What it gives you |
|---|---|
| Agent browsers | Run a browser session that stays logged in, exposes pixels to agents, and can be resumed by a human. |
| Human handoff | Let an operator open the same live desktop, inspect the state, and continue from where automation stopped. |
| GUI automation | Drive desktop apps with mouse, keyboard, clipboard, windows, accessibility, and shell commands. |
| Persistent workspaces | Keep files, browser profiles, installed tools, and local state across stop/start cycles. |

Source: src/routes/docs/concepts/+page.md
Description: The canonical MIOSA product model, from mutable sandboxes to immutable releases, stable deployments, persistent data, and customer-owned infrastructure.

# Core Concepts

MIOSA gives developers and agents a safe development loop without making production mutable.
You work in a Sandbox, inspect the result through a Preview, and publish a frozen candidate Release.
After MIOSA verifies that candidate, promotion moves the Deployment's stable URL to the new Version.

If you read only one line, remember this:

**Sandbox (mutable) → Preview → Publish → Release (immutable) → Verify → Promote → Deployment (stable URL).**

The old Version remains available for rollback.
Databases, storage, secrets, and domains remain attached to the Deployment instead of being copied into each release.

Changing a Sandbox changes development state.
It does not change production.
Production changes only when an exact immutable candidate is promoted.

This page is the **resource model**: what the MIOSA resources are and how they relate.
For the **API protocol** - authentication, token types, idempotency, rate limits, errors, and events - see [API fundamentals](/docs/fundamentals/).

# Computers (desktop product)

**Computers** are full desktop environments running in the cloud with screenshot, click, type, and keyboard APIs. They are a separate product surface from Sandboxes  -  different lifecycle, different use cases.

| | Sandbox | Computer |
|---|---|---|
| Primary use | Code execution, file I/O, dev servers, agent tool-use | Desktop GUI, browser automation, computer-use agents |
| Display | None (headless) | Desktop stream |
| Accessibility tree | No | Yes |
| Lifecycle | Short-to-medium lived, auto-suspend | Session-oriented |
| Template | `miosa-sandbox` (the default) | `miosa-desktop` |

Use Sandboxes for building apps. Use Computers when your agent or workflow needs a real screen.

You can also bring your own hardware (Mac, Linux, Windows) and register it as a Computer host via BYOC.

```bash
curl -X POST https://api.miosa.ai/api/v1/computers \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"my-computer","template_type":"miosa-desktop","size":"small"}'
```

## Three naming layers

One thing trips up every new reader: "Computer" has a specific meaning in MIOSA.

| Layer | Term | Meaning |
|-------|------|---------|
| Brand | **MIOSA** | The wordmark and platform. |
| Resource | **Computer** | The desktop GUI product. Not a generic synonym for "VM." |
| AI agent | **OSA agent** | The agent runtime. Optional; installable inside a Sandbox or Computer. |

Sandboxes are not Computers. Runtime Instances are not Computers. Computers are Computers. When you encounter older docs or code that uses "Computer" generically, substitute "Sandbox" or "Runtime Instance" based on context.

Description: Managed Postgres, Redis, object storage, volumes, and auth - the durable resources a Deployment attaches to, and how bindings inject credentials.

# Data and bindings

Sandboxes and Runtime Instances are replaceable.
Data Services are durable resources with an independent lifecycle.
Replacing a Sandbox, publishing a Release, or rolling back a Version does not delete the Deployment's database or object storage.

| Service | What it is |
|---------|-----------|
| Managed Postgres | Fully managed PostgreSQL database. Schema migrations are yours to run; MIOSA provides the connection string. |
| Managed Redis | Persistent Redis cluster for caching, queues, pub/sub. |
| Object Storage | S3-compatible bucket. Useful for uploads, assets, generated files. |
| Volumes | Block storage mounted into Runtime Instances. Persists across restarts. |
| Auth | JWT-based signup/login as a service. One env var gives your project a full auth system. |

Bindings connect a Sandbox or Deployment to those durable resources.
MIOSA resolves the binding and injects the appropriate credentials at runtime.

```
DATABASE_URL=postgresql://user:pass@host/dbname
REDIS_URL=redis://host:6379
STORAGE_BUCKET=miosa-ws123-uploads
AUTH_URL=https://auth.miosa.app/proj_abc
AUTH_JWT_SECRET=...
```

Destroying a Sandbox does not destroy its database.
Publishing a Version does not automatically make an incompatible schema safe.
Use backward-compatible expand, migrate, and contract changes so the active and previous Versions can both operate during promotion or rollback.

Managed Postgres and Auth are part of the platform Phase 6-8 rollout. The doc surface is published now so you can plan integration; some endpoints are still being wired in production.

```bash
miosa api POST /databases -d '{"name":"app-production","engine":"postgresql"}'
```

# The publish pipeline

Source: src/routes/docs/concepts/publish-pipeline/+page.md
Description: Builder, Release, Runtime Instance, Domain, Deployment, and Version - how a mutable Sandbox becomes an immutable, verified production release.

# The publish pipeline

This page is the **production side** of MIOSA: the resources a publish creates and how they relate.
For the ownership chain and the mutable Sandbox, see [Resource model](/docs/concepts/resource-model/).

## Production resources

### Builder

A **Builder** is the isolated worker for one publish operation.
It freezes the Sandbox source, runs the selected build pipeline, stores the result, and exits.
Later edits to the Sandbox cannot change that build.

Three build modes:

| Mode | Trigger | Output |
|------|---------|--------|
| Static packager | `/workspace` has only static files | Tarball served from MIOSA's edge |
| Auto-detect | Node/Python/Ruby/Go project detected | Dynamic release served by production runtimes |
| Dockerfile | `Dockerfile` present in `/workspace` | Dynamic release served by production runtimes |

The Builder is internal and short-lived.
Its job is to make production builds reproducible while the mutable Sandbox remains available for continued work.

### Release

A **Release** is the immutable artifact produced by a successful Builder run.
Its content is addressed by a SHA-256 digest and stored outside the Sandbox.
The same bytes can be started repeatedly, placed on different hosts, and verified independently.

MIOSA never edits a Release in place.
Publishing changed source creates a new Release.
That rule prevents a URL from silently serving bytes that do not match its release record.

Two shapes:

- **Static release**  -  a tarball of files (`index.html`, `app.js`, assets). MIOSA's edge serves them directly. No Runtime Instances required.
- **Dynamic release**  -  a server app artifact. Served by production runtimes.

[Releases reference →](/docs/docker-host/releases/)

### Runtime Instance

A **Runtime Instance** runs a dynamic Release in production.
MIOSA's scheduler places it, the health system checks it, and the reconciler replaces it when the actual runtime no longer matches the desired state.

Key properties:

- **Placement.** The scheduler selects a compatible host using capacity, region, and policy.
- **Scaling.** Multiple instances can serve the same Version.
- **Recovery.** Failed instances can be replaced from the immutable Release.
- **Isolation.** Production runtimes are isolated from other tenants and from the build Sandbox.

Static deployments do not need Runtime Instances.
MIOSA serves their immutable files from the edge.

[Runtime Instances reference →](/docs/docker-host/runtime-instances/)

### Domain

A **Domain** is a hostname routed to a Deployment's active Version.
The Deployment owns the route, so a new Version does not require a new customer-facing URL.

- `my-app.my-workspace.miosa.app`  -  MIOSA-managed fallback URL, instant, no DNS change needed.
- `my-app.apps.yourplatform.com`  -  tenant deployment domain for generated apps.
- `app.yourcustomer.com`  -  custom domain your customer brings; MIOSA auto-provisions a TLS certificate via Let's Encrypt.

Changing a route does not rebuild an application.
Promotion and rollback change which verified Version receives traffic behind the same Deployment URL.

[Domains reference →](/docs/docker-host/domains/)

## The immutable publish pipeline

A **Deployment** is the durable identity of a production app.
It owns the stable URL, version history, routes, environment configuration, and data bindings.

A **Version** connects one Deployment to one immutable Release plus the configuration needed to run it.
Publishing creates a candidate Version.
It does not make that candidate live merely because the build finished.

Promotion must prove that the candidate is ready, its required configuration is present, its runtime is healthy, and its route serves the expected artifact.
Only then does MIOSA update `active_version_id`.

  Dom["Domain"] -->|routes to| D
  D -->|runs| RI["Runtime Instances"]

The production transition is intentionally narrow:

1. Freeze the exact Sandbox source.
2. Build an immutable Release.
3. Create a candidate Version.
4. Verify health, routes, secrets, data bindings, and declared requirements.
5. Promote that exact Version.
6. Prove the public URL serves it.
7. Keep the previous Version available for rollback.

The object relationship remains stable across releases:

Rollback selects an earlier ready Version as `active_version_id`.
The Deployment and its domains do not change identity.
For dynamic applications, MIOSA routes traffic to healthy instances of the selected Version and retires instances that no longer belong to the active state.

A production update is accepted only when the release record, running artifact, public route, required bindings, and declared capabilities agree.
A successful build by itself is only a candidate.

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --type docker_deploy \
  --wait \
  --json
```

# Resource model

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/concepts/resource-model
Source: src/routes/docs/concepts/resource-model/+page.md
Description: The MIOSA ownership chain and the mutable development resources - Organization, Workspace, Project, Sandbox, and Preview.

# Resource model

This page is the **resource model** of the mutable side of MIOSA: the ownership chain and the development resources.
For the production resources and the publish pipeline, see [The publish pipeline](/docs/concepts/publish-pipeline/).

## The resource hierarchy

MIOSA resolves every operation through a clear ownership chain:

```text
Organization → Workspace → Project → Sandbox or Deployment
```

- An **Organization** is the top-level customer or platform account.
- A **Workspace** isolates a team, customer, or business boundary.
- A **Project** groups the development and production resources for one product.
- A **Sandbox** is the mutable place where work happens.
- A **Deployment** is the durable production identity that owns versions, routes, and bindings.

Every mutation must resolve one unambiguous organization, workspace, project, and target resource.
This prevents an agent or CLI command from publishing into the wrong customer or environment.

## Development resources

### Sandbox

A **Sandbox** is a mutable, isolated environment where an agent or developer builds an app.
It includes a complete development environment with Node, Python, git, package managers, file APIs, and a terminal.

Key properties:

- **Mutable and stateful.** Files in `/workspace` persist across commands until the sandbox is destroyed or suspended.
- **Executable.** Run commands such as `npm install`, `python app.py`, or `git clone`, with structured stdout, stderr, and exit status.
- **Agent-friendly file access.** Read, write, and synchronize source, configuration, and assets.
- **Previewable.** Expose a running port through a temporary Preview URL.
- **Snapshot-aware.** Save, fork, and restore development state without treating that snapshot as a production release.
- **Suspendable.** Idle compute can pause and later resume from durable state.

A Sandbox is not production.
Its files can change at any time, its process can stop, and its Preview can disappear while suspended.
Use it to create and test the source that will become a production candidate.

```bash
miosa create my-box --wait     # provision a sandbox and wait until it is ready
miosa exec my-box -- echo "hello from MIOSA"
```

Deep-dive on Sandboxes, file I/O, exec, previews, and the dev loop.
[Sandboxes reference →](/docs/develop/sandboxes/)

### Preview

A **Preview** is a temporary public URL that tunnels to one port inside a running Sandbox.

```
https://5173-abc12345.sandbox.miosa.ai
```

When you create a Preview, you specify the port, usually `3000` or `5173`.
MIOSA routes that hostname to the Sandbox process.
As files change and the development server reloads, the Preview changes too.

Key properties:

- **Mutable.** Every request reflects the current Sandbox process and files.
- **Ephemeral.** The URL depends on a running Sandbox and is not a durable customer URL.
- **Shareable.** Short-lived tokens allow browser access without exposing a workspace API key.

```bash
miosa preview create my-box 3000 --visibility public
```

# Tenancy

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/concepts/tenancy
Source: src/routes/docs/concepts/tenancy/+page.md
Description: White-label tenancy and external attribution - how platforms build a product on MIOSA and map MIOSA resources to their own customers.

# Tenancy

MIOSA is designed for platforms  -  you build a product on top of MIOSA, and your customers never know MIOSA exists.

The tenancy model:

- **One MIOSA organization per customer platform.** A platform account has one organization slug and server-side `msk_*` keys.
- **Workspaces and projects for downstream customers.** Use MIOSA workspaces for clients and projects for the apps, sites, documents, and workflows they create.
- **External attribution for your IDs.** Pass `external_workspace_id`, `external_user_id`, and `external_project_id` when you need your database IDs on usage, audit, and list filters.
- **Server-side key, never in the browser.** For browser-side access (embedding a preview, opening a terminal), your backend mints a short-lived scoped token. The `msk_*` key stays server-side.
Diagram:
graph TD
  Plat["Your Platform"]
  Org["MIOSA Organization<br/>one slug · one bill"]
  WS["Workspace<br/>Acme Corp"]
  Proj["Project<br/>Lead Magnet"]
  Sbx["Sandbox"]
  Dep["Deployment"]
  Plat --> Org
  Org --> WS
  WS --> Proj
  Proj --> Sbx
  Proj --> Dep

Filters are always organization-scoped server-side. You cannot cross organizations by passing different workspace, project, or external IDs.

White-label tenancy, browser tokens, attribution, and API keys.
[Platform / White-label overview →](/docs/platform/overview/)

## External attribution

**External attribution** is how you map MIOSA resources to your own users, projects, and tenants without creating MIOSA accounts for them.

Three opaque string fields are accepted on every resource that supports creation:

| Field | Purpose |
|-------|---------|
| `external_user_id` | The end-user inside your system who owns or triggered this resource |
| `external_project_id` | The project, document, or workflow in your database that this resource belongs to |
| `metadata` | Arbitrary key-value map for any additional context your platform needs |

MIOSA never interprets or validates the content of external attribution fields. They are always stored as-is.

```python
sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    external_workspace_id="acme-co",
    external_user_id="alice@example.net",
    external_project_id="invoice-bot",
)
```

For the request fields, list filters, and per-customer chargeback rollup, see [Ownership and attribution](/docs/fundamentals/attribution/) and the [Attribution reference](/docs/platform/attribution/).

# Tenant configuration

Source: src/routes/docs/concepts/tenant-config/+page.md
Description: Tenant preview domain and tenant branding - the apex hostname that replaces the MIOSA fallback preview domain and the error pages your end users see.

# Tenant configuration

## Tenant preview domain

A **tenant preview domain** is an apex hostname that replaces the MIOSA fallback preview domain in every sandbox preview URL your end users see. It is set per tenant.

When you set and verify a preview domain (for example, `yourproduct.com`), sandbox previews for your tenant are served at:

```
https://<sandbox-slug>.yourproduct.com
```

Setup is a two-step DNS verification: add a wildcard CNAME (`*.yourproduct.com`) pointing to `proxy.miosa.ai`, then call `POST /api/v1/tenant/preview-domain/verify`. MIOSA auto-provisions a wildcard TLS certificate once the CNAME resolves. Only apex domains are accepted  -  subdomains and protocol prefixes are rejected.

One preview domain per tenant. The domain applies to all sandboxes under that tenant.

```bash
# Set
curl -X PUT https://api.miosa.ai/api/v1/tenant/preview-domain \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{"preview_domain": "yourproduct.com"}'

# Verify
curl -X POST https://api.miosa.ai/api/v1/tenant/preview-domain/verify \
  -H "Authorization: Bearer msk_u_..."
```

[Tenant Preview Domain API →](/docs/api-reference/tenant-preview-domain/)

## Tenant branding

**Tenant branding** controls what your end users see on MIOSA-rendered error pages  -  the 404, 502, and gateway-timeout pages displayed when a sandbox is unavailable, a preview URL is invalid, or a custom domain is not yet verified.

Configurable fields:

| Field | Description |
|-------|-------------|
| `logo_url` | HTTPS URL to your logo image |
| `name` | Product or company name |
| `support_url` | Optional link shown on error pages for end-user support |
| `primary_color` | Hex color for CTA buttons (for example `#0066FF`) |

Branding is set via `PUT /api/v1/tenant/branding` and served immediately from cache  -  there is no propagation delay. Deleting it resets the error pages to the MIOSA defaults.

```bash
# Set branding
curl -X PUT https://api.miosa.ai/api/v1/tenant/branding \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{
    "branding": {
      "logo_url": "https://cdn.example.com/logo.png",
      "name": "Lumen",
      "primary_color": "#0066FF"
    }
  }'

# Preview and share tokens

URL: https://miosa.ai/docs/concepts/tokens
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/concepts/tokens
Source: src/routes/docs/concepts/tokens/+page.md
Description: Short-lived preview tokens (mp_*) and revocable share tokens (ms_*) for loading a sandbox preview in a browser without exposing a workspace key.

# Preview and share tokens

## Preview tokens

A **preview token** (prefix `mp_*`) is a short-lived signed token that authorizes a browser to load a sandbox preview without receiving the workspace API key.

The typical flow:

1. Your backend calls `POST /api/v1/sandboxes/{id}/preview-token` with the sandbox ID and a TTL (max 24 hours).
2. MIOSA returns an iframe-ready URL with the token embedded.
3. The browser loads that URL, for example `https://<slug>.sandbox.miosa.ai?mt=mp_...`.
4. MIOSA's edge verifies the token server-side and proxies the request to the sandbox port. The token value never grants broader access.

Preview tokens are non-renewable and non-transferable. When the TTL expires the URL returns `401`. Your backend mints a new token to restore access.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/previews/$PREVIEW/share \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{"ttl_seconds": 3600}'
```

[Browser Tokens reference →](/docs/platform/browser-tokens/)

## Share tokens

A **share token** (prefix `ms_*`) is a revocable public share URL for a sandbox preview  -  analogous to a "share link" in a document editor.

Key differences from preview tokens:

| | Preview token (`mp_*`) | Share token (`ms_*`) |
|--|------------------------|----------------------|
| Intended recipient | Your authenticated user | Anyone with the link |
| Minted by | Your backend | Your backend |
| Revocable | Yes (delete the token) | Yes (delete the token) |
| Password protection | No | Optional |
| Expiry | Required TTL | Optional |

Share tokens are useful for demos, client reviews, or collaborative previews where the recipient does not have a user account in your system. The link can be embedded as a plain URL  -  no `Authorization` header needed.

# Cookbook

URL: https://miosa.ai/docs/cookbook
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook
Source: src/routes/docs/cookbook/+page.md
Description: Every MIOSA recipe in one place, grouped by area. Sandbox procedures and platform-builder walkthroughs, each with a working code path.

# Cookbook

Practical walkthroughs for the things customers build on MIOSA. Each recipe starts with a product goal and ends with a running result, and every one is grounded in the current SDK and API.

The recipes live next to the product they belong to in the sidebar, under **Sandboxes > Recipes** and **Platform builders > Recipes**. This page is the index of all of them.

## Sandbox recipes

For running code, agents, and browsers inside a sandbox.


    The full lifecycle: user prompt to files, dev server, live preview, feedback loop, publish, and a stable production URL.


    Inject API keys and OAuth credentials into a sandbox without exposing them in code, logs, or the browser.


    Run code and stream stdout to your UI in real time: graders, workflow builders, data jobs, and AI tool execution.


    Drive the sandbox browser with an LLM over CDP: screenshot, decide, act, and watch the same session live.


## Platform builder recipes

For embedding MIOSA into your own product and charging your customers for it.


    Tag every sandbox with your own workspace and user IDs, query usage per tenant, and hand the browser a short-lived preview share token.


    Cap end-users with max_sandboxes and credit limits, pull monthly rollups keyed by external_user_id, and wire the totals into Stripe.


    Your server mints a preview token; your frontend drops it into an iframe. React, Vue, Svelte, and vanilla variants, with TTL refresh.


    React to sandbox lifecycle events through HMAC-signed webhooks or the SSE stream, with idempotency patterns.


    A product blueprint for exposing a device per user: MIOSA mapping, architecture, data model, and jobs.


## Before you start

All recipes share the same prerequisites:

- A MIOSA workspace API key (`msk_u_*`)  -  see [API Keys](/docs/platform/api-keys/)
- Node 22+ **or** Python 3.11+ installed locally
- The MIOSA SDK installed for your language:

```bash
# Python
pip install miosa

# TypeScript / Node
npm install @miosa/sdk
```

Set the key in your environment once  -  every recipe reads it from there:

```bash
export MIOSA_API_KEY="msk_u_..."
```

# Agent builds an app

URL: https://miosa.ai/docs/cookbook/agent-builds-app
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook/agent-builds-app
Source: src/routes/docs/cookbook/agent-builds-app/+page.md
Description: Your AI agent receives a prompt, writes code into a sandbox, iterates visually with live preview, checkpoints progress, branches experiments, shares with stakeholders, and publishes to production.

# Agent builds an app

~15 min Python TypeScript

> **Goal**: Wire an LLM agent to MIOSA so it can write code, boot a live dev server, iterate on feedback with real-time preview, checkpoint progress, branch experiments, share with stakeholders, track usage, and finally publish to production from a single user prompt.
>
> **What you'll use**: Sandboxes, Processes, Previews, Snapshots, Shares, Deployments, Usage

## What you'll build

A full-lifecycle function `agent_app_lifecycle(prompt)` that:

1. Generates initial files with an LLM and writes them atomically
2. Boots a dev server and mints a preview token for iframe embed
3. Iterates on user feedback: patches files, watches the file tree, preview auto-refreshes
4. Checkpoints between iterations so experiments can branch safely
5. Forks into parallel branches for A/B comparison without losing the working version
6. Creates a shareable public URL for stakeholder review
7. Tracks usage so you can bill the end-user
8. Promotes to an immutable production deployment

The pattern is model-agnostic: MIOSA is the execution layer, your agent loop is the reasoning layer.

## Prerequisites

- A MIOSA workspace API key (`msk_u_*`). See [API Keys](/docs/platform/api-keys/).
- An Anthropic API key (or substitute your preferred provider)
- Node 22+ or Python 3.11+

## Step 1: Install and configure

```bash
pip install miosa anthropic
export MIOSA_API_KEY="msk_u_..."
export ANTHROPIC_API_KEY="sk-ant-..."
```

```bash
npm install @miosa/sdk @anthropic-ai/sdk
export MIOSA_API_KEY="msk_u_..."
export ANTHROPIC_API_KEY="sk-ant-..."
```

## Step 2: Boot a sandbox and write initial files

Create a Next.js sandbox. The template already has Node, pnpm, and a scaffold,
so skip `npx create-next-app`. Use `files.writeMany` to push all initial files
in a single atomic call.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])
ai = anthropic.Anthropic(api_key=os.environ["ANTHROPIC_API_KEY"])

# Boot the sandbox
sbx = client.sandboxes.create(
    template_id="nextjs",
    timeout_sec=3600,
    external_user_id="user-42",   # attribute usage to your end-user
)

# Ask the LLM to generate the initial file set
def generate_files(prompt: str) -> list[dict]:
    msg = ai.messages.create(
        model="claude-opus-4-5",
        max_tokens=8096,
        system=(
            "You are a Next.js developer. "
            "Return a JSON array of {path, content} objects for every file you create. "
            "Paths are relative to /workspace. Content is the full file text. "
            "No explanation, just the JSON array."
        ),
        messages=[{"role": "user", "content": prompt}],
    )

    return json.loads(msg.content[0].text)

user_prompt = "Build a landing page for a dog-walking app with a hero, feature list, and CTA."
file_list = generate_files(user_prompt)

# Write all files atomically
result = sbx.files.write_many(file_list)
print(f"Written: {[f['path'] for f in result['written']]}")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
const ai = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY! });

// Boot the sandbox
const sbx = await client.sandboxes.create({
  templateId: 'nextjs',
  timeoutSec: 3600,
  externalUserId: 'user-42',
});

async function generateFiles(prompt: string): Promise<Array<{ path: string; content: string }>> {
  const msg = await ai.messages.create({
    model: 'claude-opus-4-5',
    max_tokens: 8096,
    system:
      'You are a Next.js developer. Return a JSON array of {path, content} objects for every file you create. ' +
      'Paths are relative to /workspace. Content is the full file text. No explanation, just the JSON array.',
    messages: [{ role: 'user', content: prompt }],
  });
  const block = msg.content[0];
  return JSON.parse(block.type === 'text' ? block.text : '[]');
}

const userPrompt = 'Build a landing page for a dog-walking app with a hero, feature list, and CTA.';
const fileList = await generateFiles(userPrompt);

// Write all files atomically
const result = await sbx.files.writeMany(fileList);
console.log('Written:', result.written.map(f => f.path));
```

## Step 3: Start the dev server and expose a preview

Use `processes.start` to boot the dev server as a long-running background
process. Then call `sbx.previewToken` to get a short-lived token your frontend
uses in an iframe. No public URL is required, and no `msk_*` key ever reaches
the browser.

```python
# Start the dev server as a long-running process
proc = sbx.processes.start(
    command="pnpm run dev --port 3000",
    name="nextjs-dev",
)
print(f"Dev server pid: {proc['pid']}")

# Mint a 1-hour preview token for iframe embed
token_info = sbx.preview_token(expires_in=3600)
print(f"Embed URL: {token_info['url']}")
# Send token_info['url'] to your frontend and use it as <iframe src="...">
```

```typescript
// Start the dev server as a long-running process
// (processes is available via the SDK's raw API; Python-first feature)
// For TypeScript, exec with background flag while processes lands:
await sbx.exec('pnpm run dev --port 3000 &', { cwd: '/workspace' });

// Mint a 1-hour preview token for iframe embed
const tokenInfo = await sbx.previewToken(3600);
console.log('Embed URL:', tokenInfo.url);
// Send tokenInfo.url to your frontend and use as <iframe src="...">
```

`previewToken` returns a `mp_` prefixed token embedded in the URL. It grants
read-only access to the sandbox's HTTP port for the duration of the TTL. Refresh
it before expiry by calling `previewToken` again; the new URL replaces the old
one in the iframe `src`.

## Step 4: Iterate on feedback

When the user gives feedback, generate a patch, write it with `writeMany`, and optionally watch the file tree via SSE so your UI can reflect what changed. The preview iframe auto-refreshes because the dev server is still running.

```python
def apply_feedback(sbx, current_prompt: str, feedback: str) -> list[dict]:
    """Generate a patch from LLM feedback and write it to the sandbox."""
    # Read the current file tree to give the LLM context
    tree = sbx.files.tree("/workspace", recursive=True)

    patch_prompt = (
        f"Original request: {current_prompt}\n\n"
        f"Current file tree:\n{tree}\n\n"
        f"User feedback: {feedback}\n\n"
        "Return a JSON array of {path, content} objects for ONLY the files that need to change."
    )

    msg = ai.messages.create(
        model="claude-opus-4-5",
        max_tokens=4096,
        system="You are a Next.js developer. Return only a JSON array of {path, content} objects. No explanation.",
        messages=[{"role": "user", "content": patch_prompt}],
    )

    changed_files = json.loads(msg.content[0].text)

    # Atomic write of changed files only
    result = sbx.files.write_many(changed_files)
    return result["written"]

# Example iteration
changed = apply_feedback(sbx, user_prompt, "Make the hero section taller and use a dark background")
print(f"Patched {len(changed)} files; preview refreshing automatically")
```

```typescript
async function applyFeedback(
  sbx: typeof import('@miosa/sdk').Sandbox.prototype,
  currentPrompt: string,
  feedback: string,
): Promise<Array<{ path: string; size_bytes: number }>> {
  const tree = await sbx.files.tree('/workspace', 3);

  const patchPrompt =
    `Original request: ${currentPrompt}\n\n` +
    `Current file tree:\n${JSON.stringify(tree, null, 2)}\n\n` +
    `User feedback: ${feedback}\n\n` +
    'Return a JSON array of {path, content} objects for ONLY files that need to change.';

  const msg = await ai.messages.create({
    model: 'claude-opus-4-5',
    max_tokens: 4096,
    system: 'You are a Next.js developer. Return only a JSON array of {path, content}. No explanation.',
    messages: [{ role: 'user', content: patchPrompt }],
  });
  const block = msg.content[0];
  const changedFiles: Array<{ path: string; content: string }> = JSON.parse(
    block.type === 'text' ? block.text : '[]',
  );

  const result = await sbx.files.writeMany(changedFiles);
  return result.written;
}

const changed = await applyFeedback(sbx, userPrompt, 'Make the hero section taller with a dark background');
console.log(`Patched ${changed.length} files; preview refreshing automatically`);
```

### Watch file changes over SSE

If your backend needs to push file-tree diffs to your UI in real time:

```python
# Subscribe to file change events (SSE; runs until cancelled)
for change in sbx.files.watch():
    # change = {"type": "modified"|"created"|"deleted", "path": "...", "size_bytes": N}
    print(f"[file] {change['type']}: {change['path']}")
    # Forward to your frontend over WebSocket or SSE
```

```typescript
// Subscribe to file change events
for await (const change of sbx.files.watch()) {
  // change = { type: "modified" | "created" | "deleted", path: "...", size_bytes?: N }
  console.log(`[file] ${change.type}: ${change.path}`);
  // Forward to your frontend over WebSocket or SSE
}
```

## Step 5: Preserve a known-good source

Keep the first working sandbox unchanged and fork it before the next risky iteration.
Fork uses a copy-on-write snapshot internally and returns a new sandbox with its own lifecycle.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/fork \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: fork-v2-hero-large" \
  -d '{"timeout_sec":3600}'
```

Continue experimental work in the returned sandbox.
If it fails, destroy that branch and fork the unchanged source again.

## Step 6: Branch into experiments

Fork the sandbox to create an independent copy for a risky or experimental change. The original sandbox is unaffected. Destroy the branch when you're done comparing.

```python
# Fork the current sandbox. This creates a new independent sandbox from live state.
branch = sbx.fork(name="branch-bolder-cta")
print(f"Branch sandbox: {branch.id}")

# Apply a different variant in the branch only
apply_feedback(branch, user_prompt, "Replace the CTA button with a neon green pill shape")

# Compare results, then destroy the losing branch
branch.delete()
print("Branch discarded")
```

```typescript
// Fork the current sandbox
const branch = await sbx.fork({ name: 'branch-bolder-cta' });
console.log('Branch sandbox:', branch.id);

// Apply a different variant in the branch only
await applyFeedback(branch, userPrompt, 'Replace the CTA button with a neon green pill shape');

// Compare, then destroy the losing branch
await branch.delete();
console.log('Branch discarded');
```

## Step 7: Share with stakeholders

Create a preview record for the running port, then mint a share token. The share URL is publicly accessible (read-only) for the TTL you specify.

```python
# Create a preview pointing at the dev server
preview = sbx.previews.create(port=3000)
preview_id = preview["id"]

# Mint a 24-hour public share token
share = sbx.previews.share(preview_id, ttl_seconds=86400)
print(f"Stakeholder URL: {share['share_url']}")
# Anyone with this URL can view the live sandbox in a browser. No login is required.
```

```typescript
// Create a preview pointing at the dev server
const preview = await sbx.previews.create(3000);
const previewId = String(preview.id ?? preview.preview_id ?? '');

// Mint a 24-hour public share token
const share = await sbx.previews.share(previewId, { ttl_seconds: 86400 });
console.log('Stakeholder URL:', share.share_url);
```

## Step 8: Track usage

Query usage attributed to the end-user who initiated this session. Use this to drive per-user billing in your platform.

```python
# Pull usage for this end-user over the current period
report = client.usage.report(computer_id=sbx.id)
print(f"Sandbox usage; credits: {report.get('total_credits', 'n/a')}")

# Or roll up across all sandboxes for this user (Python-first)
# user_report = client.usage.report(external_user_id="user-42", group_by="external_user_id")
```

```typescript
// Pull usage for this session
const report = await client.usage.report({ computer_id: sbx.id });
console.log(`Sandbox usage; credits: ${report.total_credits ?? 'n/a'}`);
```

## Step 9: Promote to production

When the user confirms, run the production build and deploy. The deployment is
immutable. Destroy the sandbox after deploy if you no longer need it.

```python
# Run the production build first
build = sbx.exec("pnpm run build", cwd="/workspace")
if build.exit_code != 0:
    # Self-correction turn
    fixed_files = generate_files(
        f"Fix this Next.js build error and return only the affected files:\n{build.stderr}"
    )
    sbx.files.write_many(fixed_files)
    build = sbx.exec("pnpm run build", cwd="/workspace")
    if build.exit_code != 0:
        raise RuntimeError("Build failed after correction.")

# Keep the sandbox alive if the user wants persistence instead
# sbx.update(always_on=True)

# Or deploy to production and clean up
deployment = sbx.deploy(name="dogwalk-landing")

while deployment.get("status") not in ("live", "failed"):
    time.sleep(2)
    deployment = client.deployments.get(deployment["id"])

if deployment.get("status") == "failed":
    raise RuntimeError(f"Deployment failed: {deployment.get('error')}")

print(f"Production URL: {deployment.get('url')}")

# Clean up the sandbox. The deployment is the durable artifact.
sbx.delete()
```

```typescript
// Run the production build
let build = await sbx.exec('pnpm run build', { cwd: '/workspace' });
if (build.exitCode !== 0) {
  const fixedFiles = await generateFiles(
    `Fix this Next.js build error and return only the affected files:\n${build.stderr}`,
  );
  await sbx.files.writeMany(fixedFiles);
  build = await sbx.exec('pnpm run build', { cwd: '/workspace' });
  if (build.exitCode !== 0) throw new Error('Build failed after correction.');
}

// Keep the sandbox alive if the user wants persistence instead of deploying
// await sbx.update({ always_on: true });

// Or deploy to production
const deployment = await sbx.deploy({ name: 'dogwalk-landing' });

let dep = deployment;
while (dep.status !== 'live' && dep.status !== 'failed') {
  await new Promise(r => setTimeout(r, 2000));
  dep = await client.deployments.get(String(dep.id));
}

if (dep.status === 'failed') throw new Error(`Deployment failed: ${dep.error}`);
console.log('Production URL:', dep.url);

await sbx.delete();
```

## What you learned

- `files.writeMany` pushes multiple files atomically in a single request. This is faster than individual writes and avoids partial state.
- `processes.start` keeps the dev server alive across multiple `exec` calls. The sandbox does not have to restart between iterations.
- `sbx.previewToken(expires_in)` returns an iframe-safe URL with no `msk_*` key, so it is safe to embed directly in your frontend.
- `sbx.files.watch()` is an SSE stream of file changes you can relay to your UI for live file-tree updates.
- `sbx.fork()` preserves the source and creates an independent branch from its current running state.
- `sbx.fork()` creates a fully independent copy of the live sandbox for A/B experiments. No shared state, no interference.
- `sbx.previews.create(port)` + `sbx.previews.share(preview_id, ttl_seconds=86400)` produce a public stakeholder link that expires automatically.
- `sbx.update(always_on=True)` makes a sandbox persistent after the agent session ends. Use it when the user wants to keep editing.
- `sbx.deploy(name=...)` produces an immutable release; the sandbox can be destroyed immediately after.

# Agent with secrets  -  full walkthrough

~20 min Python TypeScript Go

> **Goal**: Build a customer-support AI agent in a MIOSA sandbox that calls OpenAI and reads GitHub issues. Wire up vault-managed secrets for both credentials. Watch the audit trail in real time. Lock down egress to only those two hosts. Then rotate the OpenAI key while the agent is mid-run  -  no restart, no redeploy.

> **What you'll use**: Sandboxes, Secrets, Connect Accounts, Audit Log, Network Allowlist

## What you'll build

Diagram:
flowchart TB
  A[Your backend] --> B[Create sandbox]
  B --> C["Set OpenAI API key in vault<br/>sandbox sees $OPENAI_API_KEY (placeholder)"]
  C --> D["Connect GitHub via OAuth<br/>sandbox sees $GITHUB_TOKEN (placeholder)"]

  F --> G["Lock down egress<br/>api.openai.com + api.github.com only"]
  G --> H["Rotate OpenAI key while the agent runs<br/>next request silently picks up the new key"]

## Prerequisites

- MIOSA API key (`msk_u_*`)  -  see [API Keys](/docs/platform/api-keys/)
- OpenAI API key (`sk-proj-*`)
- GitHub account (for the OAuth step)
- Python 3.11+ or Node 22+

## Step 1  -  Install and configure

```bash
pip install miosa openai
export MIOSA_API_KEY="msk_u_..."
export MY_OPENAI_KEY="sk-proj-..."   # stored on your machine, not in the sandbox
```

```bash
npm install @miosa/sdk openai
export MIOSA_API_KEY="msk_u_..."
export MY_OPENAI_KEY="sk-proj-..."
```

```bash
go get github.com/miosa-ai/miosa-go
export MIOSA_API_KEY="msk_u_..."
export MY_OPENAI_KEY="sk-proj-..."
```

## Step 2  -  Create the sandbox

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sandbox = client.sandboxes.create(
    template_id="python-ds",
    timeout_sec=1800,   # 30 min for a long-running agent
)
print(f"Sandbox ready: {sandbox.id}")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const sandbox = await client.sandboxes.create({
  template: 'python-ds',
  timeoutSec: 1800,
});
console.log('Sandbox ready:', sandbox.id);
```

```go
package main

    "context"
    "fmt"
    "os"
    miosa "github.com/miosa-ai/miosa-go"
)

func main() {
    ctx := context.Background()
    client := miosa.NewClient(os.Getenv("MIOSA_API_KEY"))

    sandbox, err := client.Sandboxes.Create(ctx, miosa.SandboxCreate{
        Template:   "python-ds",
        TimeoutSec: 1800,
    })
    if err != nil {
        panic(err)
    }
    fmt.Println("Sandbox ready:", sandbox.ID)
}
```

## Step 3  -  Add the OpenAI key to the vault

The real key never enters the sandbox. The sandbox sees only an opaque placeholder that the MIOSA proxy swaps on the way out.

```python
sandbox.secrets.set(
    name="openai_key",
    value=os.environ["MY_OPENAI_KEY"],
    expose_as_env="OPENAI_API_KEY",
)
print("OpenAI secret saved.")
```

```typescript
await sandbox.secrets.set({
  name: 'openai_key',
  value: process.env.MY_OPENAI_KEY!,
  exposeAsEnv: 'OPENAI_API_KEY',
});
console.log('OpenAI secret saved.');
```

```go
err = sandbox.Secrets.Set(ctx, miosa.SecretSet{
    Name:        "openai_key",
    Value:       os.Getenv("MY_OPENAI_KEY"),
    ExposeAsEnv: "OPENAI_API_KEY",
})
if err != nil {
    panic(err)
}
fmt.Println("OpenAI secret saved.")
```

Verify it landed:

```python
result = sandbox.exec("echo $OPENAI_API_KEY")
print(result.stdout)
# → miosa-tok-7f2a8c1d4b2e6f0a...
# NOT the real key. Good.
```

```typescript
const result = await sandbox.exec('echo $OPENAI_API_KEY');
console.log(result.stdout);
// → miosa-tok-7f2a8c1d4b2e6f0a...
```

```go
result, _ := sandbox.Exec(ctx, "echo $OPENAI_API_KEY", miosa.ExecOpts{})
fmt.Println(result.Stdout)
// → miosa-tok-7f2a8c1d4b2e6f0a...
```

## Step 4  -  Connect GitHub via OAuth

```python
flow = sandbox.secrets.connect(
    provider="github",
    expose_as_env="GITHUB_TOKEN",
    scopes=["repo", "read:user"],
)

# Open this URL in your browser (or send it to your end-user)
print("Authorize at:", flow.authorize_url)

# Block until the user completes the OAuth dance (up to 5 minutes)
flow.wait_for_completion(timeout=300)
print("GitHub connected.")
```

```typescript
const flow = await sandbox.secrets.connect({
  provider: 'github',
  exposeAsEnv: 'GITHUB_TOKEN',
  scopes: ['repo', 'read:user'],
});

console.log('Authorize at:', flow.authorizeUrl);
await flow.waitForCompletion({ timeoutSec: 300 });
console.log('GitHub connected.');
```

```go
flow, err := sandbox.Secrets.Connect(ctx, miosa.OAuthConnect{
    Provider:    "github",
    ExposeAsEnv: "GITHUB_TOKEN",
    Scopes:      []string{"repo", "read:user"},
})
if err != nil {
    panic(err)
}
fmt.Println("Authorize at:", flow.AuthorizeURL)

if err := flow.WaitForCompletion(ctx, 300); err != nil {
    panic(err)
}
fmt.Println("GitHub connected.")
```

In a white-label product you'd send `flow.authorize_url` to your end-user instead of opening it yourself. See [White-label Credentials](/docs/security/white-label) for the full pattern.

## Step 5  -  Write and run the agent

Now write a simple agent that reads open GitHub issues and drafts replies via OpenAI. The code uses both env vars exactly as it would on a bare machine  -  no MIOSA-specific client code inside the sandbox.

```python
agent_code = '''

GITHUB_TOKEN = os.environ["GITHUB_TOKEN"]
OPENAI_API_KEY = os.environ["OPENAI_API_KEY"]
REPO = "your-org/your-repo"

def get_open_issues():
    resp = requests.get(
        f"https://api.github.com/repos/{REPO}/issues",
        headers={"Authorization": f"Bearer {GITHUB_TOKEN}"},
        params={"state": "open", "per_page": 5},
    )
    resp.raise_for_status()
    return resp.json()

def draft_reply(issue_body: str) -> str:
    payload = {
        "model": "gpt-4o-mini",
        "messages": [
            {"role": "system", "content": "You are a helpful support agent. Draft a polite reply."},
            {"role": "user", "content": issue_body},
        ],
    }
    resp = requests.post(
        "https://api.openai.com/v1/chat/completions",
        headers={
            "Authorization": f"Bearer {OPENAI_API_KEY}",
            "Content-Type": "application/json",
        },
        json=payload,
    )
    resp.raise_for_status()
    return resp.json()["choices"][0]["message"]["content"]

issues = get_open_issues()
for issue in issues:
    reply = draft_reply(issue["body"] or "(no body)")
    print(f"Issue #{issue['number']}: {issue['title']}")
    print(f"Draft reply:\\n{reply}\\n---")
'''

sandbox.files.write("/workspace/agent.py", agent_code)
result = sandbox.exec("python /workspace/agent.py")
print(result.stdout)
```

```typescript
const agentCode = `

const GITHUB_TOKEN = process.env.GITHUB_TOKEN!;
const OPENAI_API_KEY = process.env.OPENAI_API_KEY!;
const REPO = 'your-org/your-repo';

async function getOpenIssues() {
  const res = await fetch(
    \`https://api.github.com/repos/\${REPO}/issues?state=open&per_page=5\`,
    { headers: { Authorization: \`Bearer \${GITHUB_TOKEN}\` } },
  );
  return res.json() as Promise<Array<{ number: number; title: string; body: string }>>;
}

async function draftReply(issueBody: string): Promise<string> {
  const res = await fetch('https://api.openai.com/v1/chat/completions', {
    method: 'POST',
    headers: {
      Authorization: \`Bearer \${OPENAI_API_KEY}\`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({
      model: 'gpt-4o-mini',
      messages: [
        { role: 'system', content: 'You are a helpful support agent. Draft a polite reply.' },
        { role: 'user', content: issueBody },
      ],
    }),
  });
  const data = await res.json() as { choices: Array<{ message: { content: string } }> };
  return data.choices[0].message.content;
}

const issues = await getOpenIssues();
for (const issue of issues) {
  const reply = await draftReply(issue.body || '(no body)');
  console.log(\`Issue #\${issue.number}: \${issue.title}\`);
  console.log(\`Draft reply:\\n\${reply}\\n---\`);
}
`;

await sandbox.files.write('/workspace/agent.ts', agentCode);
const result = await sandbox.exec('npx tsx /workspace/agent.ts');
console.log(result.stdout);
```

## Step 6  -  Watch the audit log in real time

Open a second process (or a second async task) to tail the audit log while the agent runs. Egress audit capture is not yet enabled in the current release, so the stream is empty until it ships.

```python

def tail_audit():
    for event in sandbox.audit.tail():
        action = event.action
        host = event.host
        status = event.status_code
        transformed = ", ".join(event.request_transforms.get("secrets", {}).get("swapped", []))
        print(f"[audit] {action:8} {host} HTTP {status}  secrets={transformed or 'none'}")

t = threading.Thread(target=tail_audit, daemon=True)
t.start()

# Now run the agent
result = sandbox.exec("python /workspace/agent.py")
print(result.stdout)
```

```typescript
// Tail audit in the background
(async () => {
  for await (const event of sandbox.audit.tail()) {
    const swapped = event.requestTransforms?.secrets?.swapped?.join(', ') ?? 'none';
    console.log(`[audit] ${event.action.padEnd(8)} ${event.host} HTTP ${event.statusCode}  secrets=${swapped}`);
  }
})();

// Run the agent
const result = await sandbox.exec('npx tsx /workspace/agent.ts');
console.log(result.stdout);
```

Expected output while the agent runs:

```
[audit] allow    api.github.com   HTTP 200  secrets=none
[audit] allow    api.openai.com   HTTP 200  secrets=openai_key
[audit] allow    api.github.com   HTTP 200  secrets=none
[audit] allow    api.openai.com   HTTP 200  secrets=openai_key
```

The `secrets=openai_key` column confirms the proxy is swapping the placeholder with the real key on each OpenAI call.

## Step 7  -  Lock down the network

After observing what the agent actually calls, lock it to exactly those two hosts.

```python
sandbox.network.allow("api.openai.com")
sandbox.network.allow("api.github.com")
sandbox.network.lockdown()
print("Network locked. Only api.openai.com and api.github.com are reachable.")
```

```typescript
await sandbox.network.allow('api.openai.com');
await sandbox.network.allow('api.github.com');
await sandbox.network.lockdown();
console.log('Network locked. Only api.openai.com and api.github.com are reachable.');
```

```go
sandbox.Network.Allow(ctx, "api.openai.com", miosa.AllowOpts{})
sandbox.Network.Allow(ctx, "api.github.com", miosa.AllowOpts{})
sandbox.Network.Lockdown(ctx)
fmt.Println("Network locked.")
```

Run the agent again. It still works. Now try to reach anything else:

```bash
# Inside the sandbox after lockdown:
curl -s https://pypi.org/simple/requests/
# → blocked: 403 MIOSA-Egress-Deny
```

`pip install` and `npm install` reach package registries that won't be on your allowlist. Either pre-install everything into the template, or add `pypi.org`, `files.pythonhosted.org`, and `registry.npmjs.org` to the allowlist before locking down.

## Bonus  -  Rotate the OpenAI key while the agent is running

Rotate mid-run without restarting anything. The next request automatically uses the new key.

```python

# Start the agent in background
proc = sandbox.commands.run("python /workspace/agent.py", background=True)

# While it's running, rotate the key

time.sleep(2)   # let the agent make a few calls first

sandbox.secrets.rotate(
    name="openai_key",
    new_value="sk-proj-newrotatedkey...",
)
print("Key rotated. The agent's next OpenAI call will use the new key transparently.")

# Wait for the agent to finish
result = proc.wait()
print(result.stdout)
```

```typescript
// Start agent in background
const proc = sandbox.exec.stream('npx tsx /workspace/agent.ts', { cwd: '/workspace' });

// Rotate the key after 2 seconds
await new Promise(r => setTimeout(r, 2000));
await sandbox.secrets.rotate({
  name: 'openai_key',
  newValue: 'sk-proj-newrotatedkey...',
});
console.log('Key rotated. Next call picks up the new value automatically.');

const result = await proc.wait();
console.log(result.stdout);
```

The agent does not restart. The placeholder token in `$OPENAI_API_KEY` doesn't change. The proxy simply starts looking up the new real value on the next request that carries the placeholder.

## What you learned

- `sandbox.secrets.set` keeps the real credential out of the VM entirely.
- OAuth Connect handles token refresh transparently  -  no retry logic needed in the agent.
- `sandbox.audit.tail()` is intended to give a live stream of outbound calls with secret attribution. Egress audit capture is not yet enabled in the current release.
- `sandbox.network.lockdown()` hardens the sandbox to exactly the hosts it needs.
- `sandbox.secrets.rotate()` updates the real value mid-run  -  the placeholder and the agent code are unaffected.

## Next


    Stamp external_user_id, scope credentials per user, and embed auditing in your own dashboard.


    Operational playbook: audit-only → review suggestions → lock down → handle pending requests.

# Browser agent

URL: https://miosa.ai/docs/cookbook/browser-agent
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook/browser-agent
Source: src/routes/docs/cookbook/browser-agent/+page.md
Description: Put an LLM in the loop of a real browser running inside a sandbox. Start the sandbox browser, drive it over CDP with Playwright, and run the screenshot → action → screenshot loop.

# Browser agent

~12 min Python TypeScript

> **Goal**: Run an LLM-driven browser agent inside a MIOSA sandbox. Start the sandbox browser, connect Playwright to it over CDP, and loop: screenshot, ask the model what to do, act on the same page.
>
> **What you'll use**: Sandboxes, the sandbox browser, Playwright over CDP

## What you'll build

A `BrowserAgent` that:

1. Creates a sandbox and starts its browser.
2. Connects Playwright to the same browser the live viewer shows.
3. Enters a screenshot -> LLM -> action loop.
4. Stops when the model signals completion.

The LLM is your choice. The code below uses Anthropic Claude's vision API, but the pattern is model-agnostic.

Browser use runs inside a sandbox, so there is no separate machine to boot and no desktop to wait for. See [Browser use](/docs/browser-use/) for the full surface.

## Prerequisites

- A MIOSA workspace API key (`msk_u_*`)  -  see [API Keys](/docs/platform/api-keys/)
- An Anthropic API key (or substitute your preferred vision-capable model)
- Node 22+ or Python 3.11+

## Step 1  -  Install and configure

```bash
pip install miosa anthropic playwright
playwright install chromium
export MIOSA_API_KEY="msk_u_..."
export ANTHROPIC_API_KEY="sk-ant-..."
```

```bash
npm install @miosa/sdk @anthropic-ai/sdk playwright
npx playwright install chromium
export MIOSA_API_KEY="msk_u_..."
export ANTHROPIC_API_KEY="sk-ant-..."
```

Playwright runs on your machine as the driver. The browser it drives runs inside the sandbox.

## Step 2  -  Create a sandbox and start its browser

Create a sandbox, then start its browser. Nothing about the browser is chosen at create time: any template works, as long as its image includes Chromium and Node (the standard images do).

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])
API = "https://api.miosa.ai/api/v1"
HEADERS = {"Authorization": f"Bearer {os.environ['MIOSA_API_KEY']}"}

sandbox = client.sandboxes.create(template_id="miosa-sandbox", size="small")
print(f"Sandbox {sandbox.id}")

# Wait for the runtime to accept work.
while sandbox.state != "running":
    if sandbox.state == "error":
        raise RuntimeError(f"Sandbox failed to boot: {sandbox.state}")
    time.sleep(2)
    sandbox = client.sandboxes.get(sandbox.id)

# The browser lives inside the sandbox; ask it to start.
browser_info = requests.post(f"{API}/sandboxes/{sandbox.id}/browser", headers=HEADERS).json()["data"]
cdp_url = f"{browser_info['cdp_url']}?token={browser_info['stream_auth']}"
print(f"Live viewer: {browser_info['stream_url']}")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
const API = 'https://api.miosa.ai/api/v1';
const headers = { Authorization: `Bearer ${process.env.MIOSA_API_KEY!}` };

let sandbox = await client.sandboxes.create({ templateId: 'miosa-sandbox', size: 'small' });
console.log('Sandbox', sandbox.id);

while (sandbox.state !== 'running') {
  if (sandbox.state === 'error') throw new Error('Sandbox failed to boot');
  await new Promise(r => setTimeout(r, 2000));
  sandbox = await client.sandboxes.get(sandbox.id);
}

const started = await fetch(`${API}/sandboxes/${sandbox.id}/browser`, { method: 'POST', headers });
const { data: browser } = await started.json();
const cdpUrl = `${browser.cdp_url}?token=${browser.stream_auth}`;
console.log('Live viewer:', browser.stream_url);
```

`POST /browser` starts the browser lazily and returns `stream_url`, `cdp_url`, and `stream_auth`.
Both sockets are on `api.miosa.ai`. See [Browser use quickstart](/docs/browser-use/quickstart/) for the full set of fields.

## Step 3  -  Connect Playwright over CDP

The sandbox browser speaks the Chrome DevTools Protocol. Connect Playwright to `cdp_url` (with the `stream_auth` token appended as `?token=`) and reuse the context and page that are already open, so you act on the session a viewer would see.

```python
from playwright.sync_api import sync_playwright

playwright = sync_playwright().start()
browser = playwright.chromium.connect_over_cdp(cdp_url)
context = browser.contexts[0]
page = context.pages[0] if context.pages else context.new_page()

page.goto("https://example.com")
print("Loaded:", page.title())
```

```typescript

const browser = await chromium.connectOverCDP(cdpUrl);
const context = browser.contexts()[0];
const page = context.pages()[0] ?? (await context.newPage());

await page.goto('https://example.com');
console.log('Loaded:', await page.title());
```

`browser.close()` in Playwright detaches your driver. It does not stop the sandbox browser, so a viewer stays connected. To stop the browser and free its memory, use the browser API.

## Step 4  -  Screenshot, decide, act

The loop is the same as any vision agent: capture a screenshot, ask the model what to do next, act, repeat. The model returns a JSON action; your code executes it on the page.

```python

ai = anthropic.Anthropic(api_key=os.environ["ANTHROPIC_API_KEY"])

SYSTEM_PROMPT = """\
You control a browser page. You receive a screenshot and a task.
Respond with ONLY a JSON object  -  no explanation, no markdown fences.

Action format:
  {"type": "click", "x": <int 0-1000>, "y": <int 0-1000>}
  {"type": "type", "text": "<string>"}
  {"type": "key", "combo": "<combo>"}      e.g. "Enter", "Control+A", "Tab"
  {"type": "scroll", "direction": "up"|"down"}
  {"type": "goto", "url": "<url>"}
  {"type": "done", "result": "<summary>"}

Coordinates are 0-1000 on both axes regardless of the page size.
"""

def next_action(task, png_b64, history):
    messages = history + [{
        "role": "user",
        "content": [
            {"type": "image", "source": {"type": "base64", "media_type": "image/png", "data": png_b64}},
            {"type": "text", "text": f"Task: {task}"},
        ],
    }]
    msg = ai.messages.create(model="claude-opus-4-5", max_tokens=256, system=SYSTEM_PROMPT, messages=messages)
    return json.loads(msg.content[0].text.strip())
```

```typescript

const ai = new Anthropic({ apiKey: process.env.ANTHROPIC_API_KEY! });

const SYSTEM_PROMPT = `
You control a browser page. You receive a screenshot and a task.
Respond with ONLY a JSON object  -  no explanation, no markdown fences.

Action format:
  {"type": "click", "x": <int 0-1000>, "y": <int 0-1000>}
  {"type": "type", "text": "<string>"}
  {"type": "key", "combo": "<combo>"}
  {"type": "scroll", "direction": "up"|"down"}
  {"type": "goto", "url": "<url>"}
  {"type": "done", "result": "<summary>"}

Coordinates are 0-1000 on both axes regardless of the page size.
`.trim();

async function nextAction(task: string, pngB64: string, history: Anthropic.MessageParam[]) {
  const messages: Anthropic.MessageParam[] = [
    ...history,
    {
      role: 'user',
      content: [
        { type: 'image', source: { type: 'base64', media_type: 'image/png', data: pngB64 } },
        { type: 'text', text: `Task: ${task}` },
      ],
    },
  ];
  const msg = await ai.messages.create({ model: 'claude-opus-4-5', max_tokens: 256, system: SYSTEM_PROMPT, messages });
  const block = msg.content[0];
  return JSON.parse(block.type === 'text' ? block.text.trim() : '{}');
}
```

## Step 5  -  Execute actions on the page

Playwright works in pixels; the model works in a 0-1000 space. Scale on the way in.

```python
def screenshot_b64(page):
    return base64.b64encode(page.screenshot()).decode()

def to_pixels(page, x, y):
    size = page.evaluate("() => ({ w: window.innerWidth, h: window.innerHeight })")
    return x / 1000 * size["w"], y / 1000 * size["h"]

def execute(page, action):
    t = action["type"]
    if t == "click":
        px, py = to_pixels(page, action["x"], action["y"])
        page.mouse.click(px, py)
    elif t == "type":
        page.keyboard.type(action["text"])
    elif t == "key":
        page.keyboard.press(action["combo"])
    elif t == "scroll":
        page.mouse.wheel(0, 400 if action["direction"] == "down" else -400)
    elif t == "goto":
        page.goto(action["url"])
    elif t == "done":
        return None

    page.wait_for_timeout(500)   # let the UI settle
    return page.screenshot()
```

```typescript

const screenshotB64 = async (page: Page) =>
  (await page.screenshot()).toString('base64');

async function toPixels(page: Page, x: number, y: number) {
  const size = await page.evaluate(() => ({ w: window.innerWidth, h: window.innerHeight }));
  return { px: (x / 1000) * size.w, py: (y / 1000) * size.h };
}

async function execute(page: Page, action: Record<string, any>): Promise {
  switch (action.type) {
    case 'click': {
      const { px, py } = await toPixels(page, action.x, action.y);
      await page.mouse.click(px, py);
      break;
    }
    case 'type':    await page.keyboard.type(action.text); break;
    case 'key':     await page.keyboard.press(action.combo); break;
    case 'scroll':  await page.mouse.wheel(0, action.direction === 'down' ? 400 : -400); break;
    case 'goto':    await page.goto(action.url); break;
    case 'done':    return null;
  }
  await page.waitForTimeout(500);
  return page.screenshot();
}
```

## Step 6  -  Run the full loop

```python
TASK = "Find the 'More information...' link on example.com, click it, then report the URL you land on."
MAX_TURNS = 20

history = []
png = page.screenshot()
png_b64 = base64.b64encode(png).decode()

try:
    for turn in range(1, MAX_TURNS + 1):
        action = next_action(TASK, png_b64, history)
        print(f"Turn {turn}: {action}")
        history.append({"role": "assistant", "content": [{"type": "text", "text": json.dumps(action)}]})

        if action["type"] == "done":
            print("Done:", action.get("result"))
            break

        nxt = execute(page, action)
        if nxt is None:
            break
        png_b64 = base64.b64encode(nxt).decode()
    else:
        print(f"Reached max turns ({MAX_TURNS}) without completion.")
finally:
    browser.close()      # detach the driver
    playwright.stop()
    # Free the sandbox browser's memory, then destroy the sandbox.
    requests.delete(f"{API}/sandboxes/{sandbox.id}/browser", headers=HEADERS)
    sandbox.destroy()
```

```typescript
const TASK =
  "Find the 'More information...' link on example.com, click it, then report the URL you land on.";
const MAX_TURNS = 20;

const history: Anthropic.MessageParam[] = [];
let pngB64 = await screenshotB64(page);

try {
  for (let turn = 1; turn <= MAX_TURNS; turn++) {
    const action = await nextAction(TASK, pngB64, history);
    console.log(`Turn ${turn}:`, action);
    history.push({ role: 'assistant', content: [{ type: 'text', text: JSON.stringify(action) }] });

    if (action.type === 'done') { console.log('Done:', action.result); break; }

    const next = await execute(page, action);
    if (next === null) break;
    pngB64 = next.toString('base64');
  }
} finally {
  await browser.close();     // detach the driver
  // Free the sandbox browser's memory, then destroy the sandbox.
  await fetch(`${API}/sandboxes/${sandbox.id}/browser`, { method: 'DELETE', headers });
  await sandbox.destroy();
}
```

## Tips for reliable browser agents

- **Wait after every action.** Pages animate and reflow. `page.wait_for_timeout(500)` after each step is cheap insurance against acting on a stale screenshot.
- **Save every screenshot.** The debug loop is: screenshot N shows the state the model reasoned about to produce action N. When the agent gets stuck, inspect the saved frames.
- **Cap `MAX_TURNS` tightly (10-25).** A runaway loop burns credits. Surface an incomplete-task status instead of retrying forever.
- **Prefer `goto` over clicking through navigation** when the goal is simply to reach a URL.
- **Watch it live.** The live viewer shows the same browser your agent is driving, so you can take over when the model stalls instead of restarting the sandbox.
- **Snapshot after login.** If the task needs authenticating, snapshot immediately after login succeeds, then restore for later tasks to skip the login step. See [Snapshots and persistence](/docs/develop/snapshots/).

## When to use a Computer instead

The sandbox browser is the default for web automation: it is one browser, it bills as ordinary sandbox usage, and an agent and a person can share it.

Reach for a [Computer](/docs/computers/overview/) when the task is not a web page:

- **Full desktop applications.** A native app, an installer, a file manager, or anything that is not a browser tab.
- **Non-browser GUIs.** Windows apps, IDE windows, or a desktop that needs a real window manager.
- **Whole-screen computer use.** When the model must see and control the entire desktop, not one page. See [Computer use](/docs/computer-use/).
- **Human takeover of the machine.** When a person needs to drive a real desktop, not just a page.

Computer use drives screenshots, clicks, and key presses against a full desktop VM. The action loop is the same shape as above, but the primitives are `computer.screenshot()`, `computer.left_click()`, `computer.type()`, and `computer.key()`. See [Computer use API reference](/docs/computer-use/api-reference/). See also [Computer use vs browser use](/docs/computer-use/vs-browser-use/).

## What you learned

- The browser is part of the sandbox; there is no separate machine to boot.
- Playwright connects over CDP to the same browser a viewer can watch, so automation and a human share one session.
- The agent loop is yours: the browser executes actions, your code decides what to do next.
- Coordinates are 0-1000 in the model's view; scale to pixels with the page's inner dimensions.
- Detaching the driver (`browser.close()`) does not stop the sandbox browser; use the browser API to free its memory.

# Build a virtual-device product

URL: https://miosa.ai/docs/cookbook/build-virtual-device-product
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook/build-virtual-device-product
Source: src/routes/docs/cookbook/build-virtual-device-product/+page.md
Description: Build a Nebula-style product on MIOSA with persistent devices, files, browser work, jobs, artifacts, and connected tools.

# Build a virtual-device product

A virtual-device product gives users and agents a shared machine that keeps
state between conversations. It can hold files, run code, keep browser context,
execute jobs, connect to apps, and produce artifacts.

This is the MIOSA pattern behind Nebula-style devices, always-on operators,
agent workspaces, browser automation products, and AI company workrooms.

---

## Product promise

```text
"Give each workspace a persistent device where agents can work, remember files,
run apps, use a browser, and continue later."
```

The user should experience:

- a workspace device that does not disappear after a short timeout
- visible files and generated artifacts
- a browser or preview panel
- resumable agent sessions
- jobs that can run in the background
- connected tools and credentials
- clear usage and credits
- safe approval prompts

---

## MIOSA mapping

| Virtual-device concept | MIOSA primitive |
|---|---|
| Device | Sandbox or computer |
| Files between sessions | Persistent `/workspace`, computer storage, snapshots |
| Browser | Computer browser or browser-capable runtime |
| Code | Sandbox exec and files |
| Live server | Sandbox preview ports |
| Jobs | Scheduled agent runs that resume a device |
| Shared workspace | Workspace-scoped device policy |
| Connected apps | Managed connectors and secrets |
| Outputs | Artifacts, previews, deployments |
| Billing | Credit ledger by run/device/tool/storage |

---

## Architecture

The product owns device assignment and policy. MIOSA owns the execution layer.

---

## Data model

```sql
workspaces
  id
  primary_device_type
  primary_device_id
  credit_budget

workspace_devices
  id
  workspace_id
  miosa_device_type
  miosa_device_id
  name
  role
  status
  persistent
  latest_snapshot_id
  created_at
  updated_at

agent_sessions
  id
  workspace_id
  device_id
  runtime
  status
  last_prompt
  created_at
  updated_at

workspace_artifacts
  id
  workspace_id
  session_id
  path
  content_type
  preview_url
  download_url
  version
```

---

## Device lifecycle

Use persistent devices by default for interactive work.

```text
create workspace
  -> create primary sandbox
  -> install starter runtime/tools
  -> save first snapshot
  -> mark device ready

user sends prompt
  -> resume primary device
  -> start agent run
  -> stream events
  -> snapshot stable checkpoint

idle timeout
  -> stop compute
  -> preserve filesystem
  -> device remains resumable
```

Destroy should be explicit. Timeout should stop compute and preserve state for
normal workspaces.

For agent-building workflows, short destroy timeouts break trust. Use
persistence, snapshots, idle warnings, and explicit delete semantics.

---

## UI layout

Recommended panes:

| Pane | Shows |
|---|---|
| Chat/task | User prompts and assistant messages |
| Activity | Tool calls, command output, browser actions |
| Files | Workspace file tree and changed files |
| Preview/browser | Live server or computer stream |
| Artifacts | Downloadable outputs and versions |
| Jobs | Scheduled and running background work |
| Credits | Current balance and run cost |
| Approvals | Risky actions waiting for user confirmation |

The activity pane should show the work as it happens. If the agent writes code,
the user should see file changes and commands. If it uses a browser, the user
should see screenshots or stream events.

---

## CLI shape

Developers should be able to operate the same product from CLI:

```bash
miosa create company-workspace --template nextjs --wait
miosa device list

miosa agent run builder \
  --sandbox company-workspace \
  --no-follow

miosa run events <run-id>
miosa run files <run-id>
```

For browser work:

```bash
miosa computer create browser-qa --template miosa-desktop
miosa agent run builder \
  --computer browser-qa \
  --no-follow
```

---

## Jobs and schedules

Virtual-device products become powerful when agents can keep working.

Examples:

- daily competitor research
- weekly app QA
- CRM enrichment
- support inbox triage
- website uptime checks
- automated report generation
- recurring content drafts

Job model:

```sql
agent_jobs
  id
  workspace_id
  agent_id
  device_id
  schedule
  prompt_template
  status
  next_run_at
  budget_limit
```

Jobs should resume the assigned device, run the prompt, stream events, save
artifacts, and stop the device when idle.

---

## Connected tools

Connectors turn the device into a useful worker:

| Connector | Use |
|---|---|
| GitHub | Issues, PRs, repo context, code review |
| Slack | Notifications, summaries, approval requests |
| Google Drive | Source docs and generated files |
| Gmail | Drafts and inbox triage with approval |
| Refero | Design research and product UI references |
| Custom API key | Customer's own provider or SaaS API |

Connector tokens should be scoped to the workspace and action. The agent should
not receive tenant admin keys unless that is explicitly allowed.

---

## Safety defaults

Require approval for:

- external messages
- production deploys
- high-cost device creation
- large fleet runs
- deleting files, snapshots, devices, or deployments
- using admin credentials
- buying domains or paid resources

Always log:

- who asked
- which agent acted
- which device executed
- which connector was used
- what changed
- what credits were charged

---

## Build checklist

1. Create a workspace record.
2. Create a persistent primary sandbox.
3. Store the MIOSA sandbox id.
4. Add a visible files/artifacts pane.
5. Add a run event stream.
6. Add `agent start`, `agent task`, and `agent events` paths.
7. Add connector settings.
8. Add approval gates.
9. Add credit metering.
10. Add snapshots and resume.
11. Add optional computer for browser work.
12. Add deploy/publish path.

# Embed sandbox in an iframe

URL: https://miosa.ai/docs/cookbook/embed-sandbox-iframe
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook/embed-sandbox-iframe
Source: src/routes/docs/cookbook/embed-sandbox-iframe/+page.md
Description: Your server mints a preview token; your frontend uses it as an iframe src. Covers React, Vue, Svelte, and vanilla JS, plus token TTL refresh.

# Embed sandbox in an iframe

~8 min Python TypeScript

> **Goal**: Embed a live MIOSA sandbox in your product's UI without exposing your `msk_*` key. Your server mints a short-lived preview token; your frontend drops it into an `<iframe src>`.
>
> **What you'll use**: Sandboxes, Preview tokens

## How preview tokens work

Diagram:
sequenceDiagram
  participant BR as Browser
  participant SV as Your server
  participant MI as MIOSA API

  BR->>SV: GET /my-api/preview-token
  SV->>MI: sbx.previewToken(3600)
  MI-->>SV: { url, expires_at }
  SV-->>BR: preview URL with ?mt=mp_... token

The URL returned by `previewToken` is:

```
https://<sandbox-slug>.sandbox.miosa.ai?mt=mp_<base64url-token>
```

It is safe to put in an iframe `src` attribute. It does not contain your API key. When the token expires the sandbox is still alive  -  you mint a new token and update the `src`.

## Step 1  -  Server-side: mint the token

Your backend verifies ownership, then calls `previewToken`. Return the URL to the frontend.

```python
from fastapi import FastAPI, Depends, HTTPException
from miosa import Miosa

app = FastAPI()
client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

def get_current_user(request) -> dict:
    # Your existing session/JWT auth  -  returns {user_id, workspace_id}
    ...

@app.get("/api/sandboxes/{sandbox_id}/preview-token")
async def get_preview_token(sandbox_id: str, user=Depends(get_current_user)):
    # Ownership check  -  ensure this sandbox belongs to this user
    sbx = client.sandboxes.get(sandbox_id)
    if sbx.data.get("external_user_id") != user["user_id"]:
        raise HTTPException(403, "Forbidden")

    # Mint a 1-hour preview token
    token_info = sbx.preview_token(expires_in=3600)

    return {
        "url": token_info["url"],
        "expires_at": token_info["expires_at"],
    }
```

```typescript

const app = express();
const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

// Assumes req.user is populated by your auth middleware
app.get('/api/sandboxes/:sandboxId/preview-token', async (req, res) => {
  const { sandboxId } = req.params;
  const { userId } = (req as any).user;

  // Ownership check
  const sbx = await client.sandboxes.get(sandboxId);
  if (sbx.data.external_user_id !== userId) {
    res.status(403).json({ error: 'Forbidden' });
    return;
  }

  // Mint a 1-hour preview token
  const tokenInfo = await sbx.previewToken(3600);

  res.json({
    url: tokenInfo.url,
    expiresAt: tokenInfo.expires_at,
  });
});
```

Never return the raw `msk_*` key to the browser. The preview token URL is the only credential your frontend should ever receive, and it grants read-only access to exactly one sandbox for the duration of the TTL.

## Step 2  -  Frontend: embed the iframe

Fetch the token from your server and use the URL as the `src`. Set up a refresh timer to re-mint before expiry.

```tsx

interface SandboxEmbedProps {
  sandboxId: string;
  height?: number;
}

export function SandboxEmbed({ sandboxId, height = 600 }: SandboxEmbedProps) {
  const [previewUrl, setPreviewUrl] = useState<string | null>(null);
  const refreshTimerRef = useRef<ReturnType<typeof setTimeout>>();

  async function fetchToken() {
    const res = await fetch(`/api/sandboxes/${sandboxId}/preview-token`);
    const { url, expiresAt } = await res.json();

    setPreviewUrl(url);

    // Re-mint 60 seconds before expiry
    const ttlMs = new Date(expiresAt).getTime() - Date.now() - 60_000;
    clearTimeout(refreshTimerRef.current);
    refreshTimerRef.current = setTimeout(fetchToken, Math.max(ttlMs, 5_000));
  }

  useEffect(() => {
    fetchToken();
    return () => clearTimeout(refreshTimerRef.current);
  }, [sandboxId]);

  if (!previewUrl) {
    return <div style={{ height, background: '#111', borderRadius: 8 }}>Loading…</div>;
  }

  return (
    <iframe
      src={previewUrl}
      width="100%"
      height={height}
      style={{ border: 'none', borderRadius: 8 }}
      sandbox="allow-same-origin allow-scripts allow-forms allow-popups"
      title={`Sandbox ${sandboxId}`}
    />
  );
}
```

```vue

<template>
  <div :style="{ height: `${height}px` }">
    <div v-if="!previewUrl" :style="{ height: '100%', background: '#111', borderRadius: '8px' }">
      Loading…
    </div>
    <iframe
      v-else
      :src="previewUrl"
      width="100%"
      :height="height"
      style="border: none; border-radius: 8px"
      sandbox="allow-same-origin allow-scripts allow-forms allow-popups"
      :title="`Sandbox ${sandboxId}`"
    />
  </div>
</template>
```

```svelte

{#if previewUrl}
  <iframe
    src={previewUrl}
    width="100%"
    {height}
    style="border: none; border-radius: 8px"
    sandbox="allow-same-origin allow-scripts allow-forms allow-popups"
    title="Sandbox {sandboxId}"
  />
{:else}
  <div style="height: {height}px; background: #111; border-radius: 8px">Loading…</div>
{/if}
```

```html
<!doctype html>
<html>
  <body>
    <div id="sandbox-container" style="height:600px"></div>

  </body>
</html>
```

## Token refresh strategy

| Scenario | Recommendation |
|---|---|
| Short session (under 1 h) | Mint once with `expires_in=3600`. No refresh needed. |
| Long session | Mint with `expires_in=3600`, schedule refresh 60 s before expiry (shown above). |
| Tab inactive | Pause the refresh timer using `visibilitychange`. Mint fresh when the tab comes back. |
| Token already expired | Fetch a new token  -  the old one is silently rejected by the iframe, not a hard error. |

## CSP considerations

If your product sets a `Content-Security-Policy`, add the MIOSA preview domain to `frame-src`:

```http
Content-Security-Policy: frame-src https://*.sandbox.miosa.ai;
```

If you use a custom white-label preview domain (configured via `client.customDomains.create`), add that domain instead.

# Multi-tenant SaaS

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook/multi-tenant-saas
Source: src/routes/docs/cookbook/multi-tenant-saas/+page.md
Description: Embed MIOSA into your SaaS  -  tag sandboxes per tenant, query usage per workspace, and mint short-lived preview share tokens so customers interact directly with their sandboxes.

# Multi-tenant SaaS

~12 min Python TypeScript

> **Goal**: Embed MIOSA into a multi-tenant product. Every sandbox is tagged with your own workspace and user IDs. Usage rolls up per tenant for billing. End-users interact with their sandboxes directly from the browser without ever seeing your API key.
>
> **What you'll use**: Sandboxes, External Attribution, preview share tokens, Usage API

## What you'll build

An embedded sandbox experience inside your SaaS:

1. Your backend creates sandboxes tagged to the right customer.
2. Each tenant's usage is queryable for chargeback.
3. Your customer's browser gets a short-lived token to embed a live preview  -  no `msk_*` key anywhere client-side.

## Prerequisites

- A MIOSA workspace API key (`msk_u_*`)  -  see [API Keys](/docs/platform/api-keys/)
- Node 22+ or Python 3.11+

## Step 1  -  Install and configure

```bash
pip install miosa
export MIOSA_API_KEY="msk_u_..."
```

```bash
npm install @miosa/sdk
export MIOSA_API_KEY="msk_u_..."
```

## Step 2  -  Tag every sandbox with your IDs

Pass `external_workspace_id`, `external_user_id`, and `external_project_id` on every `sandboxes.create` call. MIOSA stores these on the resource row and propagates them to every usage record, audit event, and derived resource (previews, deployments) automatically.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

def create_sandbox_for_user(workspace_id: str, user_id: str, project_id: str):
    """Called from your request handler when a tenant starts a new sandbox."""
    sbx = client.sandboxes.create(
        template_id="miosa-sandbox",
        timeout_sec=3600,
        external_workspace_id=workspace_id,
        external_user_id=user_id,
        external_project_id=project_id,
    )
    return sbx

# Example: workspace "acme-corp", user "jane-doe", project "q3-dashboard"
sbx = create_sandbox_for_user("acme-corp", "jane-doe", "q3-dashboard")
print(f"Created sandbox {sbx.id} for acme-corp / jane-doe")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

async function createSandboxForUser(
  workspaceId: string,
  userId: string,
  projectId: string,
) {
  const sbx = await client.sandboxes.create({
    templateId: 'miosa-sandbox',
    timeoutSec: 3600,
    externalWorkspaceId: workspaceId,
    externalUserId: userId,
    externalProjectId: projectId,
  });
  return sbx;
}

// Example
const sbx = await createSandboxForUser('acme-corp', 'jane-doe', 'q3-dashboard');
console.log(`Created sandbox ${sbx.id} for acme-corp / jane-doe`);
```

Use whatever ID format your platform already has  -  UUIDs, slugs, integer strings. MIOSA stores them as text and never validates the format beyond a 255-character length limit.

## Step 3  -  List sandboxes per tenant

Filter the sandbox list by your own IDs to show a customer only their resources, or to enumerate all sandboxes for an account before billing.

```python
# All sandboxes for a workspace
acme_sandboxes = client.sandboxes.list(external_workspace_id="acme-corp")

for sbx in acme_sandboxes:
    print(f"  {sbx.id}  user={sbx.external_user_id}  status={sbx.status}")

# Narrow to a single user
jane_sandboxes = client.sandboxes.list(
    external_workspace_id="acme-corp",
    external_user_id="jane-doe",
)
```

```typescript
// All sandboxes for a workspace
const acmeSandboxes = await client.sandboxes.list({
  externalWorkspaceId: 'acme-corp',
});

for (const sbx of acmeSandboxes) {
  console.log(`  ${sbx.id}  user=${sbx.externalUserId}  status=${sbx.status}`);
}

// Narrow to a single user
const janeSandboxes = await client.sandboxes.list({
  externalWorkspaceId: 'acme-corp',
  externalUserId: 'jane-doe',
});
```

## Step 4  -  Query usage per tenant

Pull a usage report grouped by `external_workspace_id` at the end of each billing period. Use this to generate invoices or display a cost dashboard inside your product.

```python
# Monthly rollup  -  grouped by workspace
usage = client.usage.report(
    period={"start": "2026-05-01", "end": "2026-06-01"},
    group_by=["external_workspace_id"],
)

for row in usage:
    print(f"  {row['external_workspace_id']}: ${row['total_usd']:.4f}")

# Drill into a single workspace by user
acme_by_user = client.usage.report(
    period={"start": "2026-05-01", "end": "2026-06-01"},
    external_workspace_id="acme-corp",
    group_by=["external_user_id"],
)

for row in acme_by_user:
    print(f"  user={row['external_user_id']}: ${row['total_usd']:.4f}")
```

```typescript
// Monthly rollup  -  grouped by workspace
const usage = await client.usage.report({
  period: { start: '2026-05-01', end: '2026-06-01' },
  groupBy: ['external_workspace_id'],
});

for (const row of usage) {
  console.log(`  ${row.externalWorkspaceId}: $${row.totalUsd.toFixed(4)}`);
}

// Drill into a single workspace by user
const acmeByUser = await client.usage.report({
  period: { start: '2026-05-01', end: '2026-06-01' },
  externalWorkspaceId: 'acme-corp',
  groupBy: ['external_user_id'],
});

for (const row of acmeByUser) {
  console.log(`  user=${row.externalUserId}: $${row.totalUsd.toFixed(4)}`);
}
```

## Step 5  -  Mint a preview share token for direct access

Your customer's browser needs to embed a live preview. You cannot put `msk_*` in the frontend. Instead, your backend mints a short-lived **preview share token** and returns it to the client.

This step mints a **preview share token** with `previews.share`, scoped to one preview URL. A **browser access token** is a different credential: it is used to embed a live desktop stream. See [Browser access tokens](/docs/platform/browser-tokens/) if that is what you need instead.

**Backend  -  mint the token:**

```python
from fastapi import FastAPI, Depends, HTTPException
from miosa import Miosa

app = FastAPI()
client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

def get_current_user(request) -> dict:
    # Your existing auth logic  -  returns { workspace_id, user_id }
    ...

@app.get("/api/sandboxes/{sandbox_id}/preview-token")
async def get_preview_token(sandbox_id: str, user=Depends(get_current_user)):
    # Verify the sandbox belongs to this user's workspace
    sbx = client.sandboxes.get(sandbox_id)
    if sbx.external_workspace_id != user["workspace_id"]:
        raise HTTPException(403, "Forbidden")

    # Ensure a preview is running
    previews = sbx.previews.list()
    if not previews:
        preview = sbx.previews.create(port=3000)
    else:
        preview = previews[0]

    # Mint a 1-hour preview share token
    share = sbx.previews.share(
        preview.id,
        ttl_seconds=3600,
    )

    return {"share_url": share["share_url"], "expires_at": share["expires_at"]}
```

```typescript

const app = express();
const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

// Assumes req.user is populated by your auth middleware
app.get('/api/sandboxes/:sandboxId/preview-token', async (req, res) => {
  const { sandboxId } = req.params;
  const { workspaceId } = (req as any).user;

  // Ownership check
  const sbx = await client.sandboxes.get(sandboxId);
  if (sbx.externalWorkspaceId !== workspaceId) {
    res.status(403).json({ error: 'Forbidden' });
    return;
  }

  // Ensure a preview exists
  const previews = await sbx.previews.list();
  const preview =
    previews.length > 0
      ? previews[0]
      : await sbx.previews.create(3000);

  // Mint a 1-hour preview share token
  const share = await sbx.previews.share(preview.id, { ttl_seconds: 3600 });

  res.json({ shareUrl: share.share_url, expiresAt: share.expires_at });
});
```

**Frontend  -  embed the preview:**

```html
<!-- Fetch the token from your backend, then embed the iframe -->

<iframe
  id="preview-frame"
  sandbox="allow-same-origin allow-scripts allow-forms"
  style="width: 100%; height: 600px; border: 0;"
></iframe>
```

Never put `msk_*` in a `<script>` tag, environment variable exposed to the browser, or localStorage. The share token is the only credential that should reach the browser, and it grants access to exactly one preview for one hour.

## Step 6  -  Full integration wiring

Here is the complete server-side flow for a new-user onboarding request:

```python
from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

def onboard_new_project(workspace_id: str, user_id: str, project_id: str) -> dict:
    """Called when a customer creates a new project in your SaaS."""

    # 1. Boot a tagged sandbox
    sbx = client.sandboxes.create(
        template_id="miosa-sandbox",
        timeout_sec=3600,
        external_workspace_id=workspace_id,
        external_user_id=user_id,
        external_project_id=project_id,
    )

    # 2. Write an initial project scaffold
    sbx.files.write(
        "/workspace/README.md",
        f"# Project: {project_id}\nWorkspace: {workspace_id}\n",
    )

    # 3. Start the dev server
    sbx.commands.run("python3 -m http.server 3000", cwd="/workspace", background=True)

    # 4. Create a preview
    preview = sbx.previews.create(port=3000)

    # 5. Mint a preview share token
    share = sbx.previews.share(preview.id, ttl_seconds=3600)

    return {
        "sandbox_id": sbx.id,
        "preview_share_url": share["share_url"],
        "expires_at": share["expires_at"],
    }
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

async function onboardNewProject(
  workspaceId: string,
  userId: string,
  projectId: string,
): Promise<{ sandboxId: string; previewShareUrl: string; expiresAt: string }> {
  // 1. Boot a tagged sandbox
  const sbx = await client.sandboxes.create({
    templateId: 'miosa-sandbox',
    timeoutSec: 3600,
    externalWorkspaceId: workspaceId,
    externalUserId: userId,
    externalProjectId: projectId,
  });

  // 2. Write an initial scaffold
  await sbx.files.write(
    '/workspace/README.md',
    `# Project: ${projectId}\nWorkspace: ${workspaceId}\n`,
  );

  // 3. Start dev server (detached)
  sbx.exec.stream('python3 -m http.server 3000', { cwd: '/workspace' });

  // 4. Create a preview
  const preview = await sbx.previews.create(3000);

  // 5. Mint a preview share token
  const share = await sbx.previews.share(preview.id, { ttl_seconds: 3600 });

  return {
    sandboxId: sbx.id,
    previewShareUrl: share.share_url,
    expiresAt: share.data.shareTokenExpiresAt,
  };
}
```

## Step 7  -  Set per-user quotas

Cap each user so they cannot exhaust your MIOSA allocation. Quotas take effect immediately.

```python
# Free-tier: max 3 sandboxes, 1 concurrent, $5 credit cap
client.quotas.set(
    "jane-doe",
    max_sandboxes=3,
    max_concurrent=1,
    max_credit_cents=500,
)

# Pro-tier: higher limits
client.quotas.set(
    "jane-doe",
    max_sandboxes=20,
    max_concurrent=5,
    max_credit_cents=5000,
)
```

```typescript
// Quotas API via REST (SDK method landing in a future release):
await fetch(`https://api.miosa.ai/api/v1/quotas/external/jane-doe`, {
  method: 'PUT',
  headers: {
    Authorization: `Bearer ${process.env.MIOSA_API_KEY}`,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ max_sandboxes: 3, max_concurrent: 1, max_credit_cents: 500 }),
});
```

## Step 8  -  Audit log

Pull a paginated audit log to meet compliance requirements or investigate support tickets.

```python
# List recent sandbox create/destroy events
events = client.audit_log.list(
    resource_type="sandbox",
    limit=50,
)

for event in events:
    print(f"  {event.get('inserted_at')}  {event.get('action')}  {event.get('resource_id')}")
```

```typescript
const events = await client.auditLog.list({
  resource_type: 'sandbox',
  limit: 50,
});

for (const event of events) {
  console.log(`  ${event.inserted_at}  ${event.action}  ${event.resource_id}`);
}
```

## What you learned

- Three external ID fields (`external_workspace_id`, `external_user_id`, `external_project_id`) group every MIOSA resource by your own identifiers with no server-side MIOSA configuration.
- Usage reports group by the same IDs  -  direct input to your chargeback logic.
- Share tokens are resource-scoped, expirable, and the only credentials that should reach a browser. The `msk_*` key stays on the backend at all times.
- Attribution is inherited: a deployment published from a tagged sandbox carries the same external IDs automatically.
- `client.quotas.set` caps end-users before they exhaust your allocation  -  call it on plan changes, not on every request.
- `client.auditLog.list` gives you a paginated event history for compliance and support.

# Per-user quotas and billing

~10 min Python TypeScript

> **Goal**: Cap each of your end-users so they cannot exhaust your MIOSA allocation, then pull a monthly usage rollup per user to generate accurate invoices.
>
> **What you'll use**: Quotas API, Usage API

## Overview

Every sandbox created with an `external_user_id` is automatically attributed. Two APIs build on top of that:

- **Quotas**  -  hard caps per `external_user_id`: max sandboxes, max concurrent, max credits.
- **Usage**  -  period-based metering rollup queryable by `computer_id`, filterable and paginated.

Diagram:
sequenceDiagram
  participant P as Your platform
  participant M as MIOSA
  participant B as Billing system

  P->>M: Create sandbox (external_user_id="user-42")
  P->>M: Set quota (max_sandboxes=5)
  P->>M: usage.report(period_start, period_end)
  P->>B: Invoice run

## Before you start  -  attribution

Quotas and usage rollups key off `external_user_id`, the opaque identifier you stamp on each sandbox at create time. MIOSA propagates it to every usage record and audit event automatically, so there is no separate tagging step after create.

Attribution is covered end to end in [Multi-tenant SaaS](/docs/cookbook/multi-tenant-saas/): tagging at create, filtering sandboxes by tenant, and per-tenant usage. This recipe picks up from there and focuses on caps and invoicing.

## Step 1  -  Set per-user quotas

Call `client.quotas.set` once during onboarding (or whenever a user upgrades their plan). Limits take effect immediately for all subsequent sandbox creates.

```python
# Apply limits for a free-tier user
client.quotas.set(
    "user-42",
    max_sandboxes=3,       # total sandboxes this user can own
    max_concurrent=1,      # sandboxes in "running" state at once
    max_credit_cents=500,  # $5.00 cap per billing period
)

# Upgrade to a pro-tier user
client.quotas.set(
    "user-42",
    max_sandboxes=20,
    max_concurrent=5,
    max_credit_cents=5000,
)

# Remove limits (revert to tenant default)
client.quotas.delete("user-42")
```

```typescript
// Quotas are Python-first in the current SDK  -  use the raw API:
// POST /api/v1/quotas/external/{external_user_id}
// with body: { max_sandboxes, max_concurrent, max_credit_cents }

// For Python-first access (recommended):
// client.quotas.set("user-42", { max_sandboxes: 3, max_concurrent: 1 })

// TypeScript workaround until the SDK ships quotas.set():
async function setQuota(
  userId: string,
  limits: { max_sandboxes?: number; max_concurrent?: number; max_credit_cents?: number },
) {
  const res = await fetch(
    `https://api.miosa.ai/api/v1/quotas/external/${encodeURIComponent(userId)}`,
    {
      method: 'PUT',
      headers: {
        Authorization: `Bearer ${process.env.MIOSA_API_KEY}`,
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(limits),
    },
  );
  return res.json();
}

await setQuota('user-42', { max_sandboxes: 3, max_concurrent: 1, max_credit_cents: 500 });
```

`max_credit_cents` is enforced as a soft cap  -  the API rejects new sandbox creates once the user has consumed this amount in the current billing period. It does not kill running sandboxes mid-session.

## Step 2  -  Check current quota state

Before creating a sandbox on behalf of a user, check whether they have headroom. This lets you surface a friendly upgrade prompt rather than a raw API error.

```python
def check_quota(user_id: str) -> dict:
    quota = client.quotas.get(user_id)
    usage = quota.get("usage", {})

    current = usage.get("sandbox_count", 0)
    limit = quota.get("max_sandboxes") or float("inf")

    return {
        "can_create": current < limit,
        "sandbox_count": current,
        "max_sandboxes": quota.get("max_sandboxes"),
        "max_concurrent": quota.get("max_concurrent"),
        "max_credit_cents": quota.get("max_credit_cents"),
        "credit_cents_used": usage.get("credit_cents", 0),
    }

state = check_quota("user-42")
if not state["can_create"]:
    print(f"user-42 is at their sandbox limit ({state['max_sandboxes']}). Show upgrade prompt.")
else:
    sbx = client.sandboxes.create(template_id="miosa-sandbox", external_user_id="user-42")
```

```typescript
async function checkQuota(userId: string) {
  const res = await fetch(
    `https://api.miosa.ai/api/v1/quotas/external/${encodeURIComponent(userId)}`,
    {
      headers: { Authorization: `Bearer ${process.env.MIOSA_API_KEY}` },
    },
  );
  const quota = await res.json();
  const usage = quota.usage ?? {};
  const current = usage.sandbox_count ?? 0;
  const limit = quota.max_sandboxes ?? Infinity;

  return {
    canCreate: current < limit,
    sandboxCount: current,
    maxSandboxes: quota.max_sandboxes,
    creditCentsUsed: usage.credit_cents ?? 0,
    maxCreditCents: quota.max_credit_cents,
  };
}

const state = await checkQuota('user-42');
if (!state.canCreate) {
  console.log(`user-42 is at their sandbox limit. Show upgrade prompt.`);
} else {
  const sbx = await client.sandboxes.create({ templateId: 'miosa-sandbox', externalUserId: 'user-42' });
}
```

## Step 3  -  Monthly invoice rollup

At the end of each billing period, pull a usage report. The response gives you the data you need to generate per-user line items.

```python
from datetime import date, timedelta

def get_monthly_usage_per_user(year: int, month: int) -> list[dict]:
    """Returns a list of {external_user_id, total_credits, ...} rows."""
    # Build period bounds
    period_start = date(year, month, 1).isoformat()
    if month == 12:
        period_end = date(year + 1, 1, 1).isoformat()
    else:
        period_end = date(year, month + 1, 1).isoformat()

    # report() returns a summary; sessions() gives per-sandbox detail
    sessions = client.usage.sessions()  # paginate if needed

    # Group by external_user_id manually (SDK-level grouping landing in next release)
    from collections import defaultdict
    by_user = defaultdict(float)
    for session in sessions:
        uid = session.get("external_user_id")
        if uid:
            by_user[uid] += session.get("credits_used", 0) or 0

    return [{"external_user_id": uid, "credits": credits} for uid, credits in by_user.items()]

# May 2026 invoice run
rows = get_monthly_usage_per_user(2026, 5)
for row in rows:
    print(f"  user={row['external_user_id']}  credits={row['credits']:.4f}")
```

```typescript
async function getMonthlyUsagePerUser(year: number, month: number) {
  const periodStart = new Date(year, month - 1, 1).toISOString().split('T')[0];
  const periodEnd = new Date(year, month, 1).toISOString().split('T')[0];

  const sessions = await client.usage.sessions({ limit: 1000 });

  // Group by external_user_id
  const byUser = new Map<string, number>();
  for (const session of sessions) {
    const uid = String((session as any).external_user_id ?? '');
    if (uid) {
      byUser.set(uid, (byUser.get(uid) ?? 0) + Number((session as any).credits_used ?? 0));
    }
  }

  return Array.from(byUser.entries()).map(([userId, credits]) => ({ userId, credits }));
}

// May 2026 invoice run
const rows = await getMonthlyUsagePerUser(2026, 5);
for (const row of rows) {
  console.log(`  user=${row.userId}  credits=${row.credits.toFixed(4)}`);
}
```

## Connecting to Stripe (optional)

Once you have the per-user credit totals, map them to money and charge via Stripe:

```python

stripe.api_key = os.environ["STRIPE_SECRET_KEY"]

CREDIT_TO_USD = 0.01  # one MIOSA credit is one US cent

def bill_user(stripe_customer_id: str, credits: float, period: str):
    """Create a Stripe invoice item and finalize."""
    amount_cents = int(credits * CREDIT_TO_USD * 100)
    if amount_cents < 50:
        return  # below Stripe minimum  -  carry over to next period

    stripe.InvoiceItem.create(
        customer=stripe_customer_id,
        amount=amount_cents,
        currency="usd",
        description=f"MIOSA sandbox usage  -  {period} ({credits:.2f} credits)",
    )
    invoice = stripe.Invoice.create(customer=stripe_customer_id, auto_advance=True)
    stripe.Invoice.finalize_invoice(invoice.id)
    print(f"Invoice {invoice.id} sent to {stripe_customer_id}")
```

```typescript

const stripe = new Stripe(process.env.STRIPE_SECRET_KEY!);
const CREDIT_TO_USD = 0.01; // one MIOSA credit is one US cent

async function billUser(stripeCustomerId: string, credits: number, period: string) {
  const amountCents = Math.round(credits * CREDIT_TO_USD * 100);
  if (amountCents < 50) return; // below Stripe minimum

  await stripe.invoiceItems.create({
    customer: stripeCustomerId,
    amount: amountCents,
    currency: 'usd',
    description: `MIOSA sandbox usage  -  ${period} (${credits.toFixed(2)} credits)`,
  });

  const invoice = await stripe.invoices.create({ customer: stripeCustomerId, auto_advance: true });
  await stripe.invoices.finalizeInvoice(invoice.id!);
  console.log(`Invoice ${invoice.id} sent to ${stripeCustomerId}`);
}
```

## What you learned

- Every sandbox created with `external_user_id` is attributable  -  no extra tagging step required after create.
- `client.quotas.set(user_id, {...})` enforces hard caps per user. Call it on plan changes, not on every request.
- `client.quotas.get(user_id)` returns both the limits and current usage in a single call  -  use it for proactive upgrade prompts.
- `client.usage.sessions()` gives you the raw per-session metering rows you need to build an invoice rollup.
- Connecting to Stripe is a thin adapter layer  -  MIOSA gives you the credits; you decide the USD rate.

Description: React to sandbox lifecycle events using either HMAC-signed webhooks (server-to-server) or the SSE event stream (in-process). Covers both patterns, idempotency, and when to choose each.

# Sandbox events in real time

~10 min Python TypeScript

> **Goal**: React to sandbox lifecycle events  -  `sandbox.running`, `sandbox.destroyed`, `deployment.live`, and others  -  using either webhooks (durable, server-to-server) or the SSE stream (ephemeral, in-process).
>
> **What you'll use**: Webhooks, Tenant SSE event stream

## Two patterns  -  choose one

| | Webhooks | SSE stream |
|---|---|---|
| Delivery | MIOSA calls your URL | Your process pulls |
| Durability | Retried on failure | Lost if process dies |
| Auth | HMAC-SHA256 signature | Your `msk_*` key |
| Latency | ~100ms | ~50ms |
| Best for | Background jobs, billing triggers, Slack alerts | Dashboard UIs, dev-time debugging |

Both patterns carry the same event payloads. You can use both simultaneously  -  webhooks for the durable server-side reaction, SSE for the live frontend widget.

## Pattern A  -  Webhooks

### Register a webhook endpoint

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

hook = client.webhooks.create(
    url="https://api.example.net/webhooks/miosa",
    events=[
        "sandbox.running",
        "sandbox.destroyed",
        "sandbox.error",
        "deployment.live",
        "deployment.failed",
    ],
    description="Acme sandbox lifecycle",
)

# IMPORTANT: save hook["secret"] immediately  -  it is shown only once
print(f"Webhook ID: {hook['id']}")
print(f"Secret (save this): {hook.get('secret')}")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const hook = await client.webhooks.create({
  url: 'https://api.example.net/webhooks/miosa',
  events: [
    'sandbox.running',

```

### Verify the signature

Every delivery includes a `Miosa-Signature` header: `t=<unix-timestamp>,v1=<hex-digest>`. The signed payload is `<timestamp>.<raw-body>`.

```python

from fastapi import FastAPI, Request, HTTPException

app = FastAPI()
WEBHOOK_SECRET = os.environ["MIOSA_WEBHOOK_SECRET"]

def verify_signature(body: bytes, header: str, secret: str) -> bool:
    """Return True if the signature is valid and not a replay."""
    parts = dict(item.split("=", 1) for item in header.split(","))
    ts = parts.get("t", "")
    sig = parts.get("v1", "")

    # Replay guard: reject events older than 5 minutes
    if abs(time.time() - int(ts)) > 300:
        return False

    expected = hmac.new(
        secret.encode(),
        f"{ts}.{body.decode()}".encode(),
        hashlib.sha256,
    ).hexdigest()

    return hmac.compare_digest(expected, sig)

@app.post("/webhooks/miosa")
async def receive_webhook(request: Request):
    body = await request.body()
    header = request.headers.get("Miosa-Signature", "")

    if not verify_signature(body, header, WEBHOOK_SECRET):
        raise HTTPException(400, "Invalid signature")

    event = json.loads(body)
    event_type = event.get("type")

    # Idempotency: check event["id"] against your DB before processing
    event_id = event.get("id")

    if event_type == "sandbox.running":
        sandbox_id = event.get("data", {}).get("id")
        print(f"Sandbox {sandbox_id} is running  -  start your downstream job")

    elif event_type == "sandbox.destroyed":
        sandbox_id = event.get("data", {}).get("id")
        print(f"Sandbox {sandbox_id} destroyed  -  record billing event")

    elif event_type == "deployment.live":
        url = event.get("data", {}).get("url")
        print(f"Deployment live at {url}  -  notify user")

    # Always return 200 quickly; do heavy work asynchronously
    return {"ok": True}
```

```typescript

const app = express();
app.use(express.raw({ type: 'application/json' })); // raw body for signature check

const WEBHOOK_SECRET = process.env.MIOSA_WEBHOOK_SECRET!;

function verifySignature(body: Buffer, header: string, secret: string): boolean {
  const parts = Object.fromEntries(header.split(',').map(p => p.split('=')));
  const { t: ts, v1: sig } = parts;
  if (!ts || !sig) return false;

  // Replay guard: reject events older than 5 minutes
  if (Math.abs(Date.now() / 1000 - Number(ts)) > 300) return false;

  const expected = createHmac('sha256', secret)
    .update(`${ts}.${body.toString()}`)
    .digest('hex');

  return timingSafeEqual(Buffer.from(expected, 'hex'), Buffer.from(sig, 'hex'));
}

app.post('/webhooks/miosa', (req, res) => {
  const body = req.body as Buffer;
  const header = req.headers['miosa-signature'] as string ?? '';

  if (!verifySignature(body, header, WEBHOOK_SECRET)) {
    res.status(400).json({ error: 'Invalid signature' });
    return;
  }

  const event = JSON.parse(body.toString());
  const { type: eventType, id: eventId, data } = event;

  // Idempotency: check eventId against your DB before processing

  switch (eventType) {
    case 'sandbox.running':
      console.log(`Sandbox ${data?.id} is running  -  start downstream job`);
      break;
    case 'sandbox.destroyed':
      console.log(`Sandbox ${data?.id} destroyed  -  record billing event`);
      break;
    case 'deployment.live':
      console.log(`Deployment live at ${data?.url}  -  notify user`);
      break;
  }

  // Always return 200 quickly
  res.json({ ok: true });
});
```

### Idempotency

MIOSA retries webhook delivery on failure (5xx, timeout). Your handler must be idempotent. The simplest approach is to persist `event.id` in a seen-events table before processing:

```python

conn = sqlite3.connect("/var/lib/acme/events.db")
conn.execute(
    "CREATE TABLE IF NOT EXISTS seen_events (event_id TEXT PRIMARY KEY)"
)

def process_event(event: dict):
    event_id = event["id"]
    try:
        conn.execute("INSERT INTO seen_events VALUES (?)", (event_id,))
        conn.commit()
    except sqlite3.IntegrityError:
        # Already processed  -  skip
        return

    # Safe to process now
    handle_event(event)
```

```typescript
const seenEvents = new Set<string>(); // use Redis or a DB table in production

function processEvent(event: Record<string, unknown>) {
  const eventId = String(event.id ?? '');
  if (seenEvents.has(eventId)) return; // already processed
  seenEvents.add(eventId);

  handleEvent(event);
}
```

## Pattern B  -  SSE event stream

Use the tenant SSE stream for in-process listeners  -  dashboard backends, dev-time monitoring, or any scenario where you want to react inside your running process rather than receive callbacks.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

# Stream all tenant-scoped events  -  runs until cancelled
for event in client.events.stream():
    event_type = event.get("type", "")

    if event_type == "sandbox.running":
        print(f"[running]   {event['data']['id']}")
    elif event_type == "sandbox.destroyed":
        print(f"[destroyed] {event['data']['id']}")
    elif event_type == "sandbox.error":
        print(f"[error]     {event['data']['id']}  -  {event['data'].get('error')}")
    elif event_type.startswith("deployment."):
        print(f"[deploy]    {event_type}  -  {event.get('data', {}).get('url', '')}")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

// Stream all tenant-scoped events
// (TenantEvents is available as a standalone resource)
const eventStream = new TenantEvents((client as any).http);

for await (const event of eventStream.stream()) {
  const type = event.type ?? '';

  if (type === 'sandbox.running') {
    console.log(`[running]   ${(event as any).data?.id}`);
  } else if (type === 'sandbox.destroyed') {
    console.log(`[destroyed] ${(event as any).data?.id}`);
  } else if (type === 'sandbox.error') {
    console.log(`[error]     ${(event as any).data?.id}  -  ${(event as any).data?.error}`);
  } else if (type.startsWith('deployment.')) {
    console.log(`[deploy]    ${type}  -  ${(event as any).data?.url ?? ''}`);
  }
}
```

### Filter by event type

The stream accepts a `types` filter to reduce noise:

```python
# Receive only deployment events
for event in client.events.stream(types=["deployment.live", "deployment.failed"]):
    print(event)
```

```typescript
for await (const event of eventStream.stream(['deployment.live', 'deployment.failed'])) {
  console.log(event);
}
```

## Event catalog

| Event type | Trigger |
|---|---|
| `sandbox.running` | Sandbox finished booting |
| `sandbox.paused` | Sandbox suspended (idle timeout or manual pause) |
| `sandbox.destroyed` | Sandbox deleted |
| `sandbox.error` | Unrecoverable sandbox failure |
| `sandbox.snapshot.ready` | Snapshot upload completed |
| `sandbox.share.created` | Preview share token minted |
| `sandbox.share.revoked` | Preview share token revoked |
| `deployment.live` | Deployment promoted to live |
| `deployment.failed` | Deployment build or promotion failed |

## Choosing between patterns

Use **webhooks** when:

- You need durability (your process may restart)
- You're triggering background jobs, billing events, or Slack notifications
- You want MIOSA to push rather than your process to pull

Use the **SSE stream** when:

- You're building a live dashboard widget
- You're writing a short-lived script or dev tool
- You want the simplest possible integration with no webhook endpoint to deploy

# Streaming code execution

URL: https://miosa.ai/docs/cookbook/streaming-code-execution
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/cookbook/streaming-code-execution
Source: src/routes/docs/cookbook/streaming-code-execution/+page.md
Description: Run a long Python script in a sandbox and stream stdout to your UI in real time via SSE, with backpressure handling.

# Streaming code execution

~8 min Python TypeScript

> **Goal**: Run a long-running script inside a sandbox and stream every stdout line to your frontend UI in real time  -  no polling, no buffering the full output.
>
> **What you'll use**: Sandboxes, SSE events, exec streaming

## What you'll build

A minimal code-execution console: your backend creates a sandbox, runs a script, and pipes the sandbox SSE event stream back to the browser. The browser displays each line as it arrives. Looks like this in the terminal:

```
[00:01] Starting data pipeline...
[00:03] Loaded 50,000 rows
[00:05] Processing batch 1/10...
[00:09] Processing batch 2/10...
...
[01:12] Done. Output written to /workspace/output.csv
```

## Prerequisites

- A MIOSA workspace API key (`msk_u_*`)  -  see [API Keys](/docs/platform/api-keys/)
- Node 22+ or Python 3.11+

## Step 1  -  Install and configure

```bash
pip install miosa
export MIOSA_API_KEY="msk_u_..."
```

```bash
npm install @miosa/sdk
export MIOSA_API_KEY="msk_u_..."
```

## Step 2  -  Write a long-running script into the sandbox

Create a sandbox and write the script you want to execute. The script here simulates a ten-batch data pipeline with a sleep between batches.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sbx = client.sandboxes.create(template_id="miosa-sandbox", timeout_sec=300)

script = """\

BATCHES = 10
print("Starting data pipeline...", flush=True)
time.sleep(1)

for i in range(1, BATCHES + 1):
    print(f"Processing batch {i}/{BATCHES}...", flush=True)
    # simulate work
    time.sleep(0.8)

print("Done. Output written to /workspace/output.csv", flush=True)
"""

sbx.files.write("/workspace/pipeline.py", script)
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const sbx = await client.sandboxes.create({
  templateId: 'miosa-sandbox',
  timeoutSec: 300,
});

const script = `

BATCHES = 10
print("Starting data pipeline...", flush=True)
time.sleep(1)

for i in range(1, BATCHES + 1):
    print(f"Processing batch {i}/{BATCHES}...", flush=True)
    time.sleep(0.8)

print("Done. Output written to /workspace/output.csv", flush=True)
`;

await sbx.files.write('/workspace/pipeline.py', script);
```

## Step 3  -  Stream exec output

Use `exec.stream(...)` (Python and TypeScript) to receive lines as they arrive rather than waiting for the process to exit.

```python

def ts() -> str:
    return datetime.datetime.now().strftime("%M:%S")

# exec.stream yields ExecEvent objects as lines arrive
for event in sbx.exec.stream("python3 /workspace/pipeline.py"):
    if event.type == "stdout":
        print(f"[{ts()}] {event.line}")
    elif event.type == "stderr":
        print(f"[{ts()}] ERR: {event.line}", file=sys.stderr)
    elif event.type == "exit":
        print(f"Process exited with code {event.exit_code}")
        break
```

```typescript
const now = () => new Date().toISOString().substring(14, 19);

// execStream returns an async iterable of exec events
for await (const event of sbx.execStream('python3 /workspace/pipeline.py')) {
  if (event.type === 'stdout') {
    process.stdout.write(`[${now()}] ${event.line}\n`);
  } else if (event.type === 'stderr') {
    process.stderr.write(`[${now()}] ERR: ${event.line}\n`);
  } else if (event.type === 'exit') {
    console.log(`Process exited with code ${event.exitCode}`);
    break;
  }
}
```

## Step 4  -  Forward the stream to a browser via SSE

In a real application your backend runs the sandbox exec and forwards each line to the browser over an HTTP SSE response. Below is the pattern for both a Python ASGI server (FastAPI) and a Node HTTP handler.

```python
from fastapi import FastAPI
from fastapi.responses import StreamingResponse
from miosa import Miosa

app = FastAPI()
client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

@app.post("/run")
async def run_script(body: dict):
    """
    Accepts { "script": "..." } in the request body.
    Returns an SSE stream of execution events.
    """
    sbx = client.sandboxes.create(template_id="miosa-sandbox", timeout_sec=120)
    sbx.files.write("/workspace/script.py", body["script"])

    def event_generator():
        try:
            for event in sbx.exec.stream("python3 /workspace/script.py"):
                if event.type == "stdout":
                    payload = json.dumps({"type": "stdout", "line": event.line})
                    yield f"data: {payload}\n\n"
                elif event.type == "stderr":
                    payload = json.dumps({"type": "stderr", "line": event.line})
                    yield f"data: {payload}\n\n"
                elif event.type == "exit":
                    payload = json.dumps({"type": "exit", "code": event.exit_code})
                    yield f"data: {payload}\n\n"
                    break
        finally:
            sbx.delete()

    return StreamingResponse(
        event_generator(),
        media_type="text/event-stream",
        headers={
            "Cache-Control": "no-cache",
            "X-Accel-Buffering": "no",  # disable nginx buffering
        },
    )
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const server = http.createServer(async (req, res) => {
  if (req.method !== 'POST' || req.url !== '/run') {
    res.writeHead(404).end();
    return;
  }

  // Read request body
  const chunks: Buffer[] = [];
  for await (const chunk of req) chunks.push(chunk as Buffer);
  const { script } = JSON.parse(Buffer.concat(chunks).toString());

  // SSE headers  -  must be set before any write
  res.writeHead(200, {
    'Content-Type': 'text/event-stream',
    'Cache-Control': 'no-cache',
    'X-Accel-Buffering': 'no',
    Connection: 'keep-alive',
  });

  const sbx = await client.sandboxes.create({
    templateId: 'miosa-sandbox',
    timeoutSec: 120,
  });

  try {
    await sbx.files.write('/workspace/script.py', script);

    for await (const event of sbx.execStream('python3 /workspace/script.py')) {
      const payload = JSON.stringify(event);
      res.write(`data: ${payload}\n\n`);

      if (event.type === 'exit') break;
    }
  } finally {
    res.end();
    await sbx.delete();
  }
});

server.listen(3000, () => console.log('Listening on http://localhost:3000'));
```

Set `X-Accel-Buffering: no` when running behind nginx. Without it, nginx buffers the SSE response and the browser receives events in chunks rather than one by one.

## Step 5  -  Consume in the browser

A minimal browser snippet that connects to the SSE endpoint and appends each line to a `<pre>` element:

```html
<!doctype html>
<html>
  <body>
    <button id="run">Run pipeline</button>
    <pre id="output" style="background:#111;color:#0f0;padding:1rem;min-height:200px"></pre>

  </body>
</html>
```

`EventSource` only supports GET requests. If you need to pass a script body, use a two-step flow: POST `/run` to create a job and get back a `job_id`, then `GET /run/:job_id/stream` over EventSource.

## Backpressure

The MIOSA SSE stream pushes events as they arrive. If your client (browser tab, UI component) is slow, the network layer buffers them. For most exec workloads this is fine.

For very high-throughput scripts (millions of log lines), apply backpressure explicitly:

```python

# Rate-limit to 200 lines/sec to avoid overwhelming a browser client
MAX_LINES_PER_SEC = 200
bucket = MAX_LINES_PER_SEC

for event in sbx.exec.stream("python3 /workspace/heavy.py"):
    if event.type == "stdout":
        if bucket <= 0:
            # Drop or summarize  -  never block the generator
            continue
        bucket -= 1
        yield f"data: {json.dumps({'line': event.line})}\n\n"
    elif event.type == "exit":
        break
```

```typescript
let bucket = 200; // refill every second
const refill = setInterval(() => { bucket = 200; }, 1000);

try {
  for await (const event of sbx.execStream('python3 /workspace/heavy.py')) {
    if (event.type === 'stdout') {
      if (bucket > 0) {
        bucket--;
        res.write(`data: ${JSON.stringify({ line: event.line })}\n\n`);
      }
      // else: drop the line  -  client is keeping up with summaries
    } else if (event.type === 'exit') {
      break;
    }
  }
} finally {
  clearInterval(refill);
}
```

## Long-running server processes

For servers or daemons that must survive across multiple `exec` calls, use `processes.start` instead of exec with a background flag. The process keeps running even when your driver script moves on.

```python
# Start a long-running server  -  stays alive between exec calls
proc = sbx.processes.start(
    command="python3 -m http.server 8080",
    name="http-server",
)
print(f"Server running  -  pid {proc['pid']}")

# Do other work…

# Tail the last 50 lines of output
logs = sbx.processes.logs(proc["pid"], tail=50)
print(logs)

# List all running processes
for p in sbx.processes.list():
    print(f"  {p['pid']}  {p['command']}  {p['status']}")

# Stop cleanly when done
sbx.processes.stop(proc["pid"])
```

```typescript
// processes is Python-first in the current SDK.
// For TypeScript, use exec with a detached background command:
await sbx.exec('python3 -m http.server 8080 &', { cwd: '/workspace' });

// Check it is up:
const check = await sbx.exec('curl -s http://localhost:8080/', { cwd: '/workspace' });
console.log('Server responded:', check.stdout.slice(0, 80));
```

Use `processes.start` (Python) when you need to tail logs or stop the process programmatically later. Use a backgrounded `exec` command for simpler cases where you only need the process to keep running.

## What you learned

- `exec` with streaming yields events as the process runs  -  no waiting for exit.
- `stdout`, `stderr`, and `exit` are the three event types to handle.
- SSE responses need `X-Accel-Buffering: no` behind nginx to avoid buffering.
- For high-throughput output, a token-bucket rate limiter protects the browser client.
- `processes.start` (Python) keeps a server or daemon alive independently of exec calls, with named process management and log tailing.

## Next


    Wire a streaming exec into an LLM agent loop that self-corrects on build errors.


    React to sandbox lifecycle events via webhooks or the SSE stream.

# Data retention and deletion

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data-retention
Source: src/routes/docs/data-retention/+page.md
Description: What MIOSA keeps, for how long, and what "delete" actually removes for sandboxes, snapshots, the audit log, usage records, and stored data.

# Data retention and deletion

This page describes what MIOSA keeps and for how long, and what each delete operation removes. Where a retention window is not published, the page says so rather than guessing.

## Sandboxes

Deleting a sandbox (`DELETE /api/v1/sandboxes/{id}`) permanently deletes the record, removes its saved filesystem state, and settles billing. There is no undo. Use pause when the user is done for now but may come back.

A paused sandbox keeps its workspace until it is destroyed. Destroy it when the saved state should be removed.

## Snapshots

Snapshots have their own lifecycle and can end in a `deleted` state, either because you deleted them or because a retention policy removed them. Deleting a snapshot does not affect sandboxes that were previously restored from it. See [Snapshots and persistence](/docs/develop/snapshots/) for the full status list.

If you are relying on a specific retention window for snapshots, confirm it for your tenant before you depend on it.

## Audit log

Egress audit events are retained for **90 days** for every tenant, and longer on enterprise plans. The [Egress API](/docs/api-reference/egress/) documents the audit query endpoint and its retention.

The audit log is for security and compliance, not billing. Usage records are separate and carry the same attribution.

## Usage and credit records

Usage records drive billing and chargeback. Credit balances and transactions are read through the [Credits API](/docs/api-reference/credits/); credits expire **180 days** from purchase.

## Webhook events

Failed webhook deliveries are retried eight times over roughly **15.5 hours** (within a 24-hour window). After that the event is dropped, so if you need to backfill missed events, read the audit log or usage records instead of relying on redelivery.

## Volumes and stored data

Sandboxes and storage services are separate lifecycles. Destroying a sandbox does not delete a [Volume](/docs/data/volumes/) or an object storage bucket; delete those explicitly when their data should go.

## Stricter retention

MIOSA does not publish a zero-data-retention mode. If you need stricter or shorter retention than the defaults here, contact [support](/docs/support/) to discuss the terms for your tenant before you build on them.


    What survives pause, restore, and fork, and what a snapshot does not save.


    What every audit row records and how to query it.

# Auth-as-a-Service

URL: https://miosa.ai/docs/data/auth
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/auth
Source: src/routes/docs/data/auth/+page.md
Description: Opt-in end-user signup, login, and JWT issuance for a sandbox or deployment.

Managed end-user auth is live.
Auth is **opt-in** and disabled by default.
Enable it for a sandbox or deployment and MIOSA provisions the auth schema in the linked managed database.
The runtime receives `AUTH_URL`, `AUTH_JWT_SECRET`, and `AUTH_DATABASE_URL`.

## Opt-in model

Auth is disabled by default.
A sandbox or deployment has no managed signup surface until you enable it.
This prevents accidental exposure of authentication endpoints.

**Enable via API:**
```bash
curl -X POST https://api.miosa.ai/api/v1/project-auth/enable \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "resource_type": "sandbox",
    "resource_id": "'"$SANDBOX_ID"'",
    "config": {
      "signup_enabled": true,
      "email_confirm_required": false,
      "token_expiry_sec": 3600
    }
  }'
```

If the linked database is still provisioning, the endpoint returns `202` with `state: "pending"`.
Poll the status endpoint until auth is active:

```bash
curl \
  "https://api.miosa.ai/api/v1/project-auth/status?resource_type=sandbox&resource_id=$SANDBOX_ID" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

For running sandboxes, MIOSA attempts to synchronize the auth variables into the current runtime.
Deployment changes follow the deployment environment and release lifecycle.

---

Auth is the opt-in managed-auth experience.
When enabled, MIOSA provisions auth tables in the linked database.
The app receives:
```

AUTH_URL=https://api.miosa.ai/api/v1/app-auth/sandbox/<sandbox-id>
AUTH_JWT_SECRET=<random 64-char hex>
AUTH_DATABASE_URL=postgresql://...
```

The generated app uses them like this:
```typescript
// Sign up a new end user
const res = await fetch(`${process.env.AUTH_URL}/signup`, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({ email, password }),
})
const { access_token, user } = await res.json()

// Verify a JWT in the app's own API

const claims = jwt.verify(token, process.env.AUTH_JWT_SECRET!)
const userId = claims.sub
```

That's the agent-on-day-zero experience: agent writes a signup flow on day zero, never has to ask the user to configure auth.

| Organization SSO (SAML) | Available (configure per organization; enforce SSO for members) |

Not offered today: refresh tokens, magic links, OAuth providers such as Google and GitHub, MFA and TOTP, and passkeys and WebAuthn. Plan for the flows above, and hold your own session lifetime outside the access token. See [Known limitations](/docs/known-limitations/) for the full list.

## Endpoints
`AUTH_URL` already points at the resource-specific base (`.../app-auth/<type>/<id>`).
Append the action path:
```http
POST   {AUTH_URL}/signup                   create an end-user account → JWT
POST   {AUTH_URL}/login                    authenticate → JWT
POST   {AUTH_URL}/verify                   verify a JWT, returns the claims
POST   {AUTH_URL}/password-reset           request a reset link (sends email*)
POST   {AUTH_URL}/password-reset/confirm   complete the reset with the token
POST   {AUTH_URL}/email/confirm            confirm an email with the token
```
\* `/password-reset` and `/email/confirm` only send mail once email delivery is
configured; see below. The endpoints succeed regardless; the email is the part
that needs setup.

## Configuring email delivery

Password reset and email verification generate the token and call the send, but
the email itself only goes out once an email provider is wired up. **Until then,
those endpoints return success but no email is sent** (the platform logs
`email_not_configured` and skips it; it never crashes the auth flow).

MIOSA currently sends built-in auth email through an operator-managed delivery provider.
See [Transactional Email](/docs/data/email/) for the verification checklist and white-label sender boundaries.
There is no self-service per-resource sender credential in the current public contract.

> Today email sends from a single platform-wide address. Per-project and
> custom-domain senders, so each white-label brand's emails come from its own
> domain, are not offered today.

## End users are not MIOSA users

Important distinction:

- **MIOSA platform user** = the developer / platform builder. Authenticates with `msk_*` API keys or JWT sessions issued by MIOSA. Has access to the MIOSA dashboard.
- **End user of a generated app** = the visitor to an app YOUR PLATFORM built (e.g. a customer logging into an app your platform built). Authenticates against the per-project `AUTH_URL`. Has no MIOSA account.

These are completely separate auth systems. The same email can be a MIOSA platform user AND an end user of someone's app; they're different records, with different password hashes.

## Per-project isolation

Each enabled resource receives an isolated auth scope and JWT secret.
A token issued for one resource cannot authenticate against a different resource.

This makes the "end user signs up to a generated app" pattern safe even when the same MIOSA tenant hosts thousands of independent end-user apps.

## Row-level security (Postgres pattern)

When combined with managed [Postgres](/docs/data/postgres/), the auth JWT carries the user ID (`sub` claim). Your runtime code uses it for row-level filtering:
```typescript
const claims = jwt.verify(token, process.env.AUTH_JWT_SECRET!)

const orders = await pool.query(
  "SELECT * FROM orders WHERE customer_id = $1",
  [claims.sub]
)
```

Or use Postgres RLS policies if your Postgres has them enabled:
```sql
ALTER TABLE orders ENABLE ROW LEVEL SECURITY;
CREATE POLICY order_owner ON orders
  USING (customer_id = current_setting('jwt.claims.sub')::uuid);
```

## Bring your own auth?

Yes. Skip the managed auth, set your own `AUTH_URL` and `AUTH_JWT_SECRET` to point at Clerk / Auth0 / your own service. MIOSA's runtime injects whatever you set.

## Python SDK

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Get current managed-auth status and config
status = miosa.project_auth.status(
    resource_type="sandbox",
    resource_id=sandbox_id,
)
print(status)  # {"enabled": false, ...}

# Enable project auth (with optional config kwargs)
miosa.project_auth.enable(
    resource_type="sandbox",
    resource_id=sandbox_id,
    signup_enabled=True,
)

# Update config after enabling
miosa.project_auth.update(
    resource_type="sandbox",
    resource_id=sandbox_id,
    signup_enabled=False,
)

# Disable when no longer needed
miosa.project_auth.disable(
    resource_type="sandbox",
    resource_id=sandbox_id,
)
```

# Transactional Email

URL: https://miosa.ai/docs/data/email
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/email
Source: src/routes/docs/data/email/+page.md
Description: Configure MIOSA-managed transactional email for project auth, password reset, email confirmation, and platform notifications.

# Transactional Email

MIOSA uses transactional email for platform notifications and for per-project
end-user auth flows such as password reset and email confirmation.

This page separates three different email patterns:

| Pattern | Who owns it | Examples |
|---|---|---|
| **MIOSA-managed auth email** | MIOSA/operator | Password reset, email confirmation, security notices |
| **App-owned transactional email** | The generated app/customer | Receipts, booking confirmations, workflow notices |
| **Enterprise/private sender setup** | MIOSA + customer/operator | White-label sender domains, private SMTP, compliance-bound delivery |

The live MIOSA-managed auth path uses Resend today. That does not mean Resend is
the only email provider a customer app can use. It means the built-in Project
Auth sender currently reads the platform Resend configuration.

## What email covers

| Flow | Uses this config? | Notes |
|---|---:|---|
| Project Auth password reset | Yes | Sends a reset link for an end user of a generated app. |
| Project Auth email confirmation | Yes | Sends a confirmation link after signup when email verification is enabled. |
| Platform admin/user notifications | Yes | Uses the same Resend API key, with platform mailer settings. |
| Customer application transactional email | No | Wire the app to its own provider integration or runtime secret. |
| Customer marketing/campaign email | No | Usually belongs in the customer app or marketing stack, not MIOSA auth. |

## MIOSA-managed auth email

MIOSA operators configure the shared delivery provider and sender identity for the built-in Auth-as-a-Service product.
Customer applications do not receive or manage the platform delivery credential.

If platform delivery is unavailable, auth can still generate reset or confirmation tokens, but the corresponding email is not delivered.
Do not treat a successful password-reset response as proof that a message reached the provider or inbox.

## Other provider options

For application-level email, the generated app can use whichever provider the
customer chooses. Common patterns:

| Provider model | Good for | How it should be wired |
|---|---|---|
| **Resend** | Developer-friendly transactional email | Store the app's `RESEND_API_KEY` as a project/runtime secret and call Resend from app code. |
| **Postmark** | High-deliverability transactional email | Store a server token as a secret; app owns templates and sender verification. |
| **SendGrid** | Larger enterprise email programs | Store API key as a secret or enterprise integration; app owns templates/categories. |
| **Mailgun** | Domain-heavy transactional email | Store API key/domain as secrets; app owns routing and logs. |
| **SMTP relay** | Enterprise/private mail infrastructure | Store SMTP host/user/password as secrets or configure a private deployment path. |
| **Customer-owned service** | Regulated or on-prem environments | Scope network path, credentials, audit, and data handling in the enterprise deployment. |

The important rule: app-owned providers are not the same as MIOSA's built-in
auth mailer. App email belongs to the application runtime; MIOSA auth email
belongs to the platform control plane.

## Platform mailer and notifications

The platform mailer and Auth-as-a-Service use operator-managed delivery configuration.
Platform notification and app-auth sender policies can differ even when they use the same provider.

Do not treat a successful password-reset API response as proof an email was
sent. Check provider configuration, logs, and the provider event dashboard.

## Verification checklist

After configuring the env vars:

1. Enable Project Auth for a fresh project or sandbox.
2. Create a test end user through `{AUTH_URL}/signup`.
3. Call `{AUTH_URL}/password-reset` for that email.
4. Confirm the backend does not log `email_not_configured`.
5. Confirm the configured provider accepts the message.
6. Confirm the reset link reaches the inbox and `{AUTH_URL}/password-reset/confirm` accepts the token.

## White-label and enterprise senders

Today the built-in auth mailer is platform-operated. For a white-label or
enterprise customer that needs mail from its own domain, scope these items
explicitly:

- sender domain and DNS records;
- SPF, DKIM, DMARC, bounce, and complaint handling;
- whether MIOSA sends through a managed provider or the customer's private SMTP;
- per-tenant branding and template ownership;
- audit logs and delivery visibility;
- whether the setup is cloud, private-network, or on-prem.

Do not promise a dashboard toggle that lets each project configure its own auth sender.

## App-owned email

Generated apps can still send their own email by storing provider credentials
as project/runtime secrets and calling the provider directly from app code.
That is the right path for product emails such as receipts, invites, booking
confirmations, reports, or customer-specific notifications.

    Enable per-project signup, login, JWTs, password reset, and email confirmation.

# Fractal enterprise data

MIOSA and Fractal run dedicated Fractal instances for massive-scale structured data and computation, secure and isolated for enterprise and government.

Talk to us

Fractal is not provisioned like Postgres, MySQL, Redis, Qdrant, Storage, Auth, or Volumes. A production Fractal instance is scoped as a MIOSA and Fractal enterprise engagement covering data residency, connector shape, credentials, sync, audit, approvals, and operating model.

---

## Who it is for

Fractal is for organizations whose data work is bigger than an application database:

- **Enterprise and government** teams that own client-wide structured data and cannot let AI near their systems of record.
- **Regulated industries**: electric, gas, and water utilities, telecommunications, financial services, healthcare, insurance, logistics, retail, oil and gas, and public sector.
- **Very large datasets**: millions of records, accounts, meters, claims, invoices, transactions, or assets.
- **High-volume computation** that is trivial per row and expensive once it runs millions of times a day.

If your data fits comfortably in a MIOSA Postgres database, you do not need Fractal. Use the built-in primitives and come back when the population, the calculation, or the isolation requirement outgrows them.

## What you get


    A Fractal instance dedicated to your data and workloads, separate from shared application databases and scoped to your organization.



    Client-wide structured records and the high-volume calculations that are too large for the application database hot path.



    A private data plane. AI reads and writes on the Fractal twin; your systems of record stay untouched.



    Instances grow with the population and the job volume, for enterprise and government scale.



    Compare, score, and reconcile across source systems, with evidence and an auditable outcome for every run.



    Cloud, private, or government-oriented deployment, chosen to fit your residency and operating requirements.


## How it fits with MIOSA

MIOSA is the product and operating layer. Apps, agents, deployments, review queues, and audit trails connect to the Fractal data plane, so your customers see one branded product and never touch the data plumbing underneath.


    The product surface: apps, agents, sandboxes, computers, deployments, auth, review, approvals, audit, webhooks.


    The enterprise data substrate: client-wide structured data, high-volume calculation, reconciliation, and a private data plane.


    Authoritative records, production write policy, residency requirements, and final source-system promotion.


Diagram:
flowchart LR
  Sources["Customer systems of record"] -->|one-way sync| Instance["Fractal instance"]
  Instance -->|datasets and findings| Surface["MIOSA product surface"]
  Surface -.->|approved promotion| Sources

Read it left to right:

1. Customer systems of record remain the source of truth, and data flows into the instance one way.
2. Fractal turns raw source data and business rules into an explicit enterprise model: ontology, taxonomy, and schema mapping.
3. The Fractal instance runs the heavy data work against that model: high-volume calculations, reconciliation, and derived datasets.
4. MIOSA turns those outputs into a product: apps, agents, deployments, review queues, approvals, reports, and audit trails.
5. Promotion back to source is controlled and approved. The agent proposes; customer policy decides what is promoted.

### The enterprise data model

The first job is not to point an agent at raw tables. The first job is to map the customer's world into a usable data model: the entities, relationships, names, identifiers, calculations, source-of-truth rules, and approval rules the business actually runs on.

| Model layer | Examples | Why it matters |
|---|---|---|
| **Ontology** | Customer, account, claim, invoice, meter | Names the real business objects |
| **Taxonomy** | Product families, claim types, rate classes | Groups data into business-safe categories |
| **Schema mapping** | Source fields, IDs, joins, units | Connects source systems to a stable model |
| **Calculation definitions** | Pricing, eligibility, reconciliation | Makes repeatable work explicit |
| **Governance rules** | Read-only and propose-only fields | Keeps agents from uncontrolled writes |

Business objects in a typical model include customer, account, claim, invoice, product, meter, asset, provider, and location. Taxonomy covers product families, claim types, customer segments, rate classes, regions, and exception categories. Governance rules mark fields read-only, propose-only, or approval-required for writeback, and set the audit requirements for each.

### Governed writeback

Fractal-backed workflows should not let AI write directly to production systems. Use a propose, review, promote shape:

```text
read scoped data
  -> run calculation or reconciliation
  -> produce finding or proposal with evidence
  -> route to human or policy approval
  -> promote through a controlled writeback service
  -> record audit outcome
```

### Connector expectations

Do not assume a public connector contract from this page. A production design is scoped with MIOSA and Fractal, and defines:

- dataset and tenant identity;
- data residency and network path;
- scoped credentials or token exchange;
- read-only, propose-only, and approval-required modes;
- sync health and freshness;
- audit and event handoff;
- writeback ownership and rollback or compensation policy.

## Fractal compared with MIOSA Postgres, Storage, and Volumes

Use the built-in primitives for normal application state. Reach for a Fractal instance when the population, the calculation, or the isolation requirement outgrows them.

| Need | MIOSA built-in | Fractal instance |
|---|---|---|
| App-local relational state | Postgres or MySQL | Not the right tool |
| Cache, queues, sessions | Redis | Not the right tool |
| Files, reports, exports | Object storage | Stores artifacts around Fractal runs |
| Durable disk for a sandbox | Volumes | Not the right tool |
| Embedding and vector search | Qdrant | Indexes Fractal outputs |
| End-user auth | Project Auth | Gates access before Fractal data |
| Client-wide structured data | Too large for the app DB | Dedicated Fractal instance |
| High-volume calculation | App code if small | Fractal-backed calculation |
| Reconciliation across sources | App code if small | Fractal-backed reconciliation |
| A private, isolated data plane | Not offered | Fractal instance in your environment |
| Keeping AI off systems of record | Not offered | Fractal digital twin, one-way sync |

## Deployment options



A managed MIOSA product surface with a Fractal instance in the partner data plane. You get the branded app and the operating workflow; Fractal runs the enterprise data plane.




The Fractal instance runs in your environment or private network, and production data never leaves your boundary. MIOSA connects to it from the product surface.




Fractal publishes government-oriented material and a government contact path. Residency, network, and procurement requirements are scoped directly with MIOSA and Fractal.



A hybrid pilot is also common: prove the workflow on a restricted export or scoped dataset before any production promotion.

## Getting started

A Fractal-backed project starts as an enterprise architecture conversation, not a connector install. The usual sequence:

1. **Talk to us.** Describe the workflow, the systems of record, and the data that concerns you.
2. **Scope the data.** Decide what the instance sees, where it runs, and how data residency is handled.
3. **Map the model.** Define the ontology, taxonomy, and schema mapping the workflow needs.
4. **Choose the deployment** and the sync, freshness, and read, propose, and writeback modes.
5. **Build the product surface.** Apps, agents, review queues, reports, and audit trails around the Fractal instance.
6. **Prove it on real data.** Run a parallel pilot before promoting anything back to source.

For a MIOSA and Fractal engagement, contact [enterprise@miosa.ai](mailto:enterprise@miosa.ai). Use this when the customer needs private data-plane planning, on-prem or customer-controlled deployment, source-system mapping, ontology and taxonomy work, or governed writeback.

## FAQ

### Is Fractal a MIOSA primitive like Postgres?

No. Postgres, MySQL, Redis, Qdrant, Storage, Auth, and Volumes are self-service primitives you create from the platform. A Fractal instance is an enterprise engagement, scoped with MIOSA and Fractal.

### Does my data have to leave my environment?

No. A private deployment keeps the instance in your environment or private network. A cloud deployment puts the instance in the partner data plane instead.

### Can AI write to my production systems?

Not directly. Data flows into the instance one way, AI works on the twin, and results are promoted back to source only through a controlled, auditable process with explicit approval.

### What scale does this target?

Millions of records, accounts, meters, claims, invoices, transactions, or assets, and calculations repeated millions of times per day. Fractal states that its production deployments run at Fortune 500 scale across utilities, telecommunications, and financial services.

### Do you publish certifications?

This page does not list certifications. Government, defense, and regulated deployments are scoped directly with MIOSA and Fractal against your requirements.

### Is there a published performance or price figure?

Fractal publishes its own figures, including 100x performance, 90 percent less infrastructure cost, and a 90-day parallel deployment, on its public site. These are Fractal's claims, not MIOSA measurements. Treat them as a starting point for a pilot, not as a contract.

## Fractal's public claims and references

Fractal publishes the partner-side architecture as a synchronized digital twin, one-way synchronization from systems of record, controlled promotion back, locality optimization, commodity hardware, and industry-specific deployments. These are Fractal's own claims.

| Reference | What it covers |
|---|---|
| [Fractal](https://fractalweb.app/) | Digital twins, structured data, performance, and cost claims. |
| [How Fractal works](https://fractalweb.app/how) | Twin architecture, one-way sync, promoted results, 90-day pilot. |
| [Why Fractal](https://fractalweb.app/why) | Corruption risk, what does not work, and the cost case. |
| [Markets](https://fractalweb.app/markets) | Utilities, telecom, finance, healthcare, insurance, government. |
| [About](https://fractalweb.app/about) | Origins, locality optimization, production deployments. |
| [Contact](https://fractalweb.app/contact) | Fractal's own intake and scheduling flow. |

## Common enterprise workflows

| Workflow | MIOSA role | Fractal role |
|---|---|---|
| Billing QA | App, review, approvals, audit | Calculation and mismatch detection |
| Claims or revenue reconciliation | Agents, evidence UI, artifacts | Reconciliation across records |
| Product variant analysis | Workflow UI, result publishing | High-volume variant calculation |
| Agent execution evaluation | Orchestration, reports, review | Structured execution outputs |
| Customer data operations | White-label product, webhooks | Client-wide structured data plane |

# MongoDB

URL: https://miosa.ai/docs/data/mongodb
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/mongodb
Source: src/routes/docs/data/mongodb/+page.md
Description: Managed MongoDB per project for document data.

Managed MongoDB is a database engine like Postgres, MySQL and Redis.
It runs the official MongoDB 7 server in its own microVM with a persistent data volume.

## What you get

A managed MongoDB 7 instance with an auto-generated root user and password, injected as `MONGODB_URI` (also `MONGO_URL`):

```
MONGODB_URI=mongodb://user:pass@host:port/miosa_db?authSource=admin
```

Standard MongoDB drivers work without modification:

```typescript

const client = new MongoClient(process.env.MONGODB_URI!)
await client.connect()

const users = client.db("miosa_db").collection("users")
await users.insertOne({ name: "Ada", createdAt: new Date() })
```

The user has the root role, so you can create any number of databases on the instance.
`authSource=admin` is part of the URL and must stay.

## Provision

```bash
miosa db create --name app-mongo --engine mongodb
```

```typescript
await miosa.databases.create({ name: "app-mongo", engine: "mongodb", size: "small" })
```

You can also choose MongoDB in the Add menu of a project, or set `managed: mongodb` on a database service in a change set.
Only major version 7 is available.

## Connection variables

| Variable | Value |
| --- | --- |
| `MONGODB_URI` | Full connection string |
| `MONGO_URL` | Same as `MONGODB_URI` |
| `MONGO_HOST`, `MONGO_PORT` | Host and port |
| `MONGO_USER`, `MONGO_PASSWORD` | Root user and password |
| `MONGO_DATABASE` | Default database name |

## Backups and restore

Backups are logical (`mongodump`, gzip archive) and cover every database on the instance except `admin` and `config`.
A restore replaces the collections the backup contains and leaves the others alone.
It never touches the `admin` database, so your issued credentials keep working.
A MongoDB backup restores only into a MongoDB database.

## Limits

- There is no table browser or query console for MongoDB. Use `mongosh` or a driver.
- There is no automatic pause when idle, as with MySQL and Redis.
- Memory, connections and storage follow the selected plan size.

# MySQL

URL: https://miosa.ai/docs/data/mysql
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/mysql
Source: src/routes/docs/data/mysql/+page.md
Description: Managed MySQL per project with durable storage and DATABASE_URL injection.

Managed MySQL is available for projects that need MySQL-compatible schemas,
frameworks, or imports. MIOSA provisions the instance, stores credentials, and
injects `DATABASE_URL` into attached sandboxes and production runtimes.

## When to use MySQL

Use managed MySQL when the application already expects MySQL semantics:

- Laravel, WordPress, or MySQL-first frameworks
- Existing customer schemas that should not be converted to Postgres
- SQL workloads that rely on MySQL-specific behavior
- SaaS templates that ship with MySQL migrations

Use [Postgres](/docs/data/postgres/) when you need richer relational features,
extensions, or Postgres-native tooling.

## Runtime contract

Applications do not need to know where the database runs. Read the injected
connection string at boot:

```bash
DATABASE_URL=mysql://user:password@host:3306/database
```

MIOSA injects the same variable into:

- sandboxes for development and agent work
- runtime instances for production deployments
- background workers that belong to the project

Lifecycle, backup, restore, credentials, logs, and metrics use the common [Databases API](/docs/api-reference/databases/).
Do not infer those values from a hostname or project slug.

## Provisioning pattern

```typescript
const project = await miosa.projects.create({
  name: "Customer Portal",
  data: { mysql: true },
});
```

For app builders and white-label platforms, create MySQL per customer project
when the generated app requires it. Keep schema migrations in the application
repo or sandbox workspace so deployments remain repeatable.

# Data

URL: https://miosa.ai/docs/data/overview
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/overview
Source: src/routes/docs/data/overview/+page.md
Description: Managed databases, object storage, auth, and volumes with explicit lifecycle, credentials, and recovery operations.

MIOSA Data services give your sandboxes and production runtime instances access to persistent storage without any external account setup. When you attach a data service to a project, MIOSA provisions the resource and injects its credentials at boot  -  your code reads `process.env.DATABASE_URL` and connects. That is the entire integration.

## Phase status

Data services ship incrementally. This table reflects verified platform state:

| Service | Status |
|---|---|
| Object Storage | **Available** - buckets, objects, presigned URLs, quota, per-tenant |
| Cron Jobs | **Available** - CLI, MCP, SDK, and backend all wired |
| Managed Postgres | **Generally available** - dedicated instances, credential injection, lifecycle operations, backup, and restore |
| Managed MySQL | **Generally available** - dedicated instances, credential injection, and lifecycle operations |
| Managed Redis | **Generally available** - per-project instances and `REDIS_URL` injection |
| Managed MongoDB | **Generally available** - per-project document databases and `MONGODB_URI` injection |
| Managed Qdrant (vector) | **Generally available** - per-project vector databases and `QDRANT_URL` injection |
| Auth (per-project end-user auth) | **Generally available** - opt-in signup, login, JWT, password reset, and email confirmation |
| Volumes (persistent block storage) | **Generally available** - create, attach, detach, delete, and meter host-local volumes |

Per-page callouts indicate any in-progress edge cases.

## Mental model

Each service fills a different role. Pick the right one for your data shape:

| Service | Use when you need | Persistence |
|---|---|---|
| **Postgres** | Relational data, joins, transactions, migrations | Durable - survives deploys and sandbox destruction |
| **MySQL** | MySQL-compatible apps, existing MySQL schemas | Durable - survives deploys and sandbox destruction |
| **Redis** | Cache, sessions, pub/sub, rate limiting | Durable (AOF/RDB) but treated as cache-class |
| **MongoDB** | Document data, flexible schemas | Durable - survives deploys and sandbox destruction |
| **Qdrant** | Vector search, semantic similarity, embeddings | Durable - collection data persists across VMs |
| **Storage** | File uploads, generated assets, binary blobs | Durable - content-addressed object store |
| **Auth** | Per-project end-user signup, login, and JWT issuance | Durable - user records outlive any VM |
| **Volumes** | Large or fast filesystem state that does not fit in Postgres | Attached to one runtime instance at a time |

## Data persists past your VMs

Sandboxes are persistent by default and can be paused, resumed, snapshotted, or destroyed.
Deployment runtime instances are replaceable.
Managed data has an independent lifecycle and is not deleted when either compute surface is replaced.

Destroying a sandbox removes the VM  -  the connected Postgres database is untouched. Publishing a new version does not migrate your schema. Rolling back a deployment does not roll back your database. Data services are managed independently of the compute that connects to them.

This is intentional. It is also why production stays available during deploys: the new version connects to the same database the old version was using.

## How credentials are injected

MIOSA can bind different database credentials to different deployment environments:
```

production runtime  →  DATABASE_URL = postgres://prod-db...
staging runtime     →  DATABASE_URL = postgres://staging-db...
```

You ship one environment variable name and MIOSA resolves the binding for that environment.
Environment isolation must be configured explicitly.
Until separate development and production databases are attached, a sandbox may share the production database.
See [Environments](/docs/docker-host/environments/).

## Quick example

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

# Create a managed Postgres database
db = miosa.databases.create(
    engine="postgres",
    engine_version="15",
    name="my-app-db",
)

print(db["id"])          # db_...
print(db["status"])      # provisioning | running

# Fetch connection credentials once ready
creds = miosa.databases.credentials(db["id"])
print(creds["url"])      # postgresql://user:pass@host:5432/dbname
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

// Create a managed Postgres database
const db = await miosa.databases.create({
  engine: "postgres",
  engineVersion: "15",
  name: "my-app-db",
})

console.log(db.id)       // db_...
console.log(db.status)   // provisioning | running

// Fetch connection credentials once ready
const creds = await miosa.databases.credentials(db.id)
console.log(creds.url)   // postgresql://user:pass@host:5432/dbname
```

```bash
# Create a managed Postgres database
curl -X POST https://api.miosa.ai/api/v1/databases \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"engine":"postgres","engine_version":"15","name":"my-app-db"}'

# Get credentials
curl https://api.miosa.ai/api/v1/databases/$DATABASE_ID/credentials \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

## How data services attach

    DEP -->|STORAGE_BUCKET + STORAGE_ENDPOINT + keys injected| ST[(Object Storage)]
    DEP -->|AUTH_URL + AUTH_JWT_SECRET injected| AU[Auth Service]

  P --> D["Data services (durable)<br/>Postgres, MySQL, Redis, MongoDB, Qdrant, Storage, Auth (opt-in), Volumes"]
  D -->|"connection env vars injected at boot"| S

Your application code reads standard environment variables and opens normal client connections.
The application remains responsible for schema migrations, backward compatibility, and safe handling of destructive operations.

## Managed database lifecycle

Managed databases expose explicit lifecycle and recovery operations:

The API supports start, stop, restart, wake, resize, branch, replica creation, backup, restore, move, credentials, logs, and metrics.
The current CLI exposes the common create, inspect, lifecycle, connect, backup, restore, logs, and metrics operations.
See [Databases API](/docs/api-reference/databases/) for the exact endpoints.

# Postgres

URL: https://miosa.ai/docs/data/postgres
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/postgres
Source: src/routes/docs/data/postgres/+page.md
Description: Managed Postgres per project with lifecycle controls, backup, restore, and DATABASE_URL injection.

Managed Postgres supports dedicated instances, `DATABASE_URL` injection, persistent storage, lifecycle operations, on-demand backup, and restore through the CLI and API.

## Provision

When a project is created with `data: { postgres: true }`, MIOSA provisions a logical database in a managed Postgres cluster, generates credentials, and injects them as env vars.

Diagram:
graph LR
    PC[Project create] -->|data.postgres=true| MP[MIOSA provisioner]
    MP --> PG[(Managed Postgres cluster)]
    PG -->|credentials generated| ENV[DATABASE_URL env var]
    ENV --> SB[Sandbox]
    ENV --> RI[Runtime Instance]

```typescript
const project = await miosa.projects.create({
  name: "Team Portal",
  data: { postgres: true },
})

// Sandboxes and runtime instances under this project boot with:
// DATABASE_URL = postgresql://user:pass@host:port/proj_xxx
```

You can also add Postgres to an existing project:
```typescript
await miosa.projects.dataServices.create(projectId, {
  type: "postgres",
  size: "small",  // small | medium | large
})
```

## Create it your way: API, CLI, or SDK

You don't need an SDK. The same managed database can be created and used three ways. All of these hit the same API.

**Raw API (curl):**
```bash
# 1. Create a Postgres database
curl -X POST https://api.miosa.ai/api/v1/databases \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "my-db", "engine": "postgresql"}'
# → { "id": "db_...", "state": "provisioning", ... }   (reaches "running" in ~30-60s)

# 2. Get the connection string once it's running
curl https://api.miosa.ai/api/v1/databases/DB_ID/credentials \
  -H "Authorization: Bearer $MIOSA_API_KEY"
# → { "data": { "recommended_url": "postgresql://user:pass@host:port/miosa_db", ... } }

# 3. Connect with anything that speaks Postgres
psql "postgresql://user:pass@host:port/miosa_db"
```
Other engines: pass `"engine": "mysql"`, `"redis"`, or `"qdrant"`.

**CLI:**
```bash
miosa api POST /databases -d '{"name": "my-db", "engine": "postgresql"}'  # create
miosa db list                     # see them + their state
miosa db connection <id>                    # open a shell to it
miosa db logs <id>                       # tail logs
miosa db backup <id>                     # snapshot
miosa api POST /databases/<id>/restore \
  -d '{"backup_id": "<backup-id>"}'          # restore
```

**SDK** (Python example below; TypeScript/Go/Elixir SDKs have the same methods).

## Connection management

Use a bounded application connection pool and size it for the database plan.
Treat the connection URL returned by the credentials endpoint as authoritative.
Do not assume a separate session or transaction pooler unless the returned database configuration explicitly advertises one.

## Where you can connect from

The connection URL points at a private MIOSA address.
It is reachable from sandboxes, computers and deployments in your organization.
It is not reachable from the public internet, so `psql` on your laptop cannot use it directly.
To work with the database from your own machine, run `psql` inside a sandbox, or open a tunnel through one.

## Schema management is yours

MIOSA doesn't run migrations for you. The recommended workflow:

1. Use your framework's migration tool (Prisma, Drizzle, Ecto, Alembic, etc.).
2. Run migrations as part of your build or startup, or as a separate one-off:

```typescript
await sandbox.exec({ cmd: "npx", args: ["prisma", "migrate", "deploy"] })
```

3. Make migrations backward-compatible (expand → migrate → contract). This keeps rollback working  -  see [Rollback](/docs/docker-host/rollback/).

## Extensions

These extensions can be used in a database: `vector`, `pg_trgm`, `pgcrypto`, `uuid-ossp`, `citext`, `hstore`, `btree_gin`, `btree_gist` and `pg_stat_statements`. Ask for the ones you want when you create the database:

```bash
miosa db create app-db --extensions vector,pg_trgm
```

Anything else (for example `adminpack` or `file_fdw`) is refused.

### pg_stat_statements is on by default

Every **new** Postgres database has `pg_stat_statements` turned on, so the console's top-queries view and your own `SELECT ... FROM pg_stat_statements` work from the first minute. It is added to the list you ask for, and `pg_stat_statements.track` is the Postgres default (`top`).

To create a database without it, send `"pg_stat_statements": false` when you create it:

```bash
miosa api POST /databases -d '{"name":"app-db","engine":"postgres","pg_stat_statements":false}'
```

Databases that already exist are not changed. To turn it on for one of them, enable the extension on that database; it takes effect the next time you restart it.

## Backups

MIOSA supports scheduled backups and on-demand backups stored outside the database runtime.
Retention depends on the database plan.

Create an on-demand backup:

```bash
miosa db backup <database-id> --json
```

Restore from a selected backup:

```bash
miosa api POST /databases/<database-id>/restore \
  -d '{"backup_id": "<backup-id>"}'
```

Restore replaces database contents.
Review the target database and backup ID before confirming the operation.

## Lifecycle and recovery

| State | Meaning |
|---|---|
| `provisioning` | MIOSA is creating storage, credentials, and the database runtime. |
| `running` | The database accepts connections. |
| `stopped` | The database was intentionally stopped. Persistent data remains attached. |
| `restarting` | MIOSA is restoring the desired-running database after maintenance or a restart request. |
| `error` | Recovery did not complete and operator action is required. |

During host maintenance, MIOSA preserves the database ID, credentials, persistent volume, bindings, and desired state.
A database that was running is restarted and verified before its host returns to active service.
An intentionally stopped database remains stopped.

## Sandboxed development with the same DB

When you create a sandbox under a project that has Postgres, the sandbox also gets `DATABASE_URL`  -  pointing at the same managed database. Two options:

1. **Shared dev DB.** Sandboxes and production both point at the production database. Fast iteration, risk of dev work affecting prod data.
2. **Per-environment DB.** Production gets one DB, staging/dev get another. Configured via [Environments](/docs/docker-host/environments/).

Default is (2) once per-environment isolation lands. Until then, sandboxes share the production DB; use schema namespacing or be careful with destructive queries.

## Connecting from a sandbox
```typescript
await sandbox.exec({
  cmd: "psql",
  args: [process.env.DATABASE_URL, "-c", "SELECT 1"],
})
```

The sandbox's `DATABASE_URL` is the same shape the runtime would see in production. Whatever code works in the sandbox works in the deployment.

## Limits

| Tier | Storage | Connections (PgBouncer) | Memory |
|---|---|---|---|
| small | 1 GB | 100 | 512 MB |
| medium | 10 GB | 200 | 2 GB |
| large | 100 GB | 500 | 8 GB |

Storage, connection, and memory limits depend on the database plan.
Inspect the database response and metrics rather than assuming automatic storage growth.

## Costs

Postgres pricing is in two parts:

- **Compute**  -  per-hour while the DB is running (always-on by default for production; can be paused for sandboxed dev DBs).
- **Storage**  -  GB-month for data plus WAL.

See [Usage & Billing](/docs/platform/usage-and-billing/). Per-database metering carries [attribution](/docs/platform/attribution/), so platforms can charge back per end-customer.

## Bring your own Postgres?

If you'd rather use an external Postgres, just set `DATABASE_URL` as an env var on the deployment and skip the managed offering:
```typescript
await miosa.deployments.env.set(deploymentId, {
  environment: "production",
  vars: { DATABASE_URL: "postgresql://...your-external-db..." },
})
```

MIOSA's runtime injects whatever you set. The managed Postgres is convenience; bringing your own is supported.

## Python SDK

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Provision a managed database
db = miosa.databases.create(
    name="team-portal-db",
    engine="postgres",
    size="small",
)
print(db["id"])  # db_...

# Get connection credentials
creds = miosa.databases.credentials(db["id"])
print(creds["url"])  # postgresql://user:pass@host:port/dbname

# Lifecycle operations
miosa.databases.stop(db["id"])
miosa.databases.start(db["id"])
miosa.databases.restart(db["id"])

# Stream logs (returns a generator of SSE events)
for event in miosa.databases.stream_logs(db["id"]):
    print(event)

# Teardown
miosa.databases.delete(db["id"])
```

# Public database endpoint

URL: https://miosa.ai/docs/data/public-endpoint
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/public-endpoint
Source: src/routes/docs/data/public-endpoint/+page.md
Description: Open a TLS-only TCP endpoint for one managed database, with an allowlist, so a laptop or an outside service can connect.

# Public database endpoint

A managed database is reachable from inside the platform by its private URL. Turn
on public networking when something outside needs to connect: a laptop, a
migration tool, an analytics job in another cloud.

```bash
miosa db public app-db                       # off or on, and the address
miosa db public app-db on                    # any source
miosa db public app-db on --allow 203.0.113.0/24 --allow 198.51.100.7
miosa db public app-db off                  # close it and free the port
```

The same calls are `GET`, `POST` and `DELETE /api/v1/databases/:id/public-networking`.

## What you get

- A host and a port from **30000-39999**, one port per database. The host is the
  edge's public address, so it does not change when the database moves host.
- `public_url` in the credentials response while it is on, and
  `DATABASE_PUBLIC_URL` in the database service's variables, so
  `${{db.DATABASE_PUBLIC_URL}}` resolves for anything that needs it.

## Security

- **TLS only.** Postgres needs `sslmode=require`; MySQL needs
  `--ssl-mode=REQUIRED` and refuses a plaintext login with error 3159. The
  certificate is self-signed, so `require` encrypts without verifying the name.
- **The allowlist closes disallowed sources before any TLS handshake.** `--allow`
  replaces the stored list, so `on` with no `--allow` means any source. Entries
  are IPs or CIDRs, at most 32.
- Limits: 100 connections per database, 20 new connections per 10 seconds per
  source IP, at most 32 TLS handshakes at once, and 2,000 public connections
  across your databases.

## Engines

Postgres, MySQL, Redis and MongoDB. Other engines answer `ENGINE_NOT_SUPPORTED`.

## Turning it off

`off`, or deleting the database, closes the port within about fifteen seconds.
Both are recorded in the audit log as `database.public_networking_enable` and
`database.public_networking_disable`.

Anything inside the platform should use the private URL. The public endpoint
exists for clients that cannot reach the private network, not as the default way
to connect.

# Qdrant (Vector Database)

URL: https://miosa.ai/docs/data/qdrant
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/qdrant
Source: src/routes/docs/data/qdrant/+page.md
Description: Per-project vector database for semantic search and embedding storage. QDRANT_URL injected at boot.

Managed Qdrant is live. Per-project dedicated instances, QDRANT_URL injection at boot, and data persistence across VM destroy are all working.

## When to use Qdrant

Use Qdrant when an agent or app needs durable semantic memory:

- Retrieval-augmented generation (RAG)
- Document and knowledge-base search
- Product or lead similarity matching
- Long-running agent memory across sessions
- Embeddings produced inside sandboxes or computers

Use object storage for the raw files and Qdrant for the vectors and payload metadata that make those files searchable.

## What you get

Per project: a dedicated Qdrant instance. Credentials injected at boot:

```
QDRANT_URL=https://qdrant.proj_xxx.miosa.internal
QDRANT_API_KEY=...
```

Use any Qdrant-compatible client:

```typescript

const client = new QdrantClient({
  url: process.env.QDRANT_URL,
  apiKey: process.env.QDRANT_API_KEY,
})

// Create a collection
await client.createCollection("documents", {
  vectors: { size: 1536, distance: "Cosine" },
})

// Upsert vectors
await client.upsert("documents", {
  points: [
    { id: 1, vector: embedding, payload: { text: "Hello world" } },
  ],
})

// Semantic search
const results = await client.search("documents", {
  vector: queryEmbedding,
  limit: 5,
  with_payload: true,
})
```

```python
from qdrant_client import QdrantClient

client = QdrantClient(
    url=os.environ["QDRANT_URL"],
    api_key=os.environ["QDRANT_API_KEY"],
)

results = client.search(
    collection_name="documents",
    query_vector=query_embedding,
    limit=5,
)
```

## Provision

Add Qdrant when creating a project:

```typescript
const project = await miosa.projects.create({
  name: "my-rag-app",
  data: { qdrant: true },
})
```

Or add to an existing project:

```typescript
await miosa.projects.dataServices.create(projectId, {
  type: "qdrant",
  size: "small",  // small | medium | large
})
```

**cURL:**

```bash
curl -X POST https://api.miosa.ai/api/v1/projects/$PROJECT_ID/data-services \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"type":"qdrant","size":"small"}'
```

## Data persists past VM destroy

Collections and vectors survive sandbox destruction and deployment rollbacks. The Qdrant instance keeps running between VM lifecycles. You do not need to re-index on every boot.

## Typical pattern: RAG pipeline

```typescript

const openai = new OpenAI()
const qdrant = new QdrantClient({
  url: process.env.QDRANT_URL,
  apiKey: process.env.QDRANT_API_KEY,
})

// Index a document
async function index(id: number, text: string) {
  const { data } = await openai.embeddings.create({
    model: "text-embedding-3-small",
    input: text,
  })
  await qdrant.upsert("docs", {
    points: [{ id, vector: data[0].embedding, payload: { text } }],
  })
}

// Query
async function query(question: string, topK = 5) {
  const { data } = await openai.embeddings.create({
    model: "text-embedding-3-small",
    input: question,
  })
  return qdrant.search("docs", {
    vector: data[0].embedding,
    limit: topK,
    with_payload: true,
  })
}
```

## Limits

| Tier | Memory | Disk | Max collections |
|---|---|---|---|
| small | 1 GB | 10 GB | 10 |
| medium | 4 GB | 50 GB | 50 |
| large | 16 GB | 200 GB | unlimited |

Vector count per collection is bounded by memory. At 1536 dimensions (OpenAI `text-embedding-3-small`), `small` fits ~100K vectors; `medium` fits ~400K.

## Bring your own Qdrant?

Yes. Set `QDRANT_URL` and `QDRANT_API_KEY` as env vars to point at an external instance (Qdrant Cloud, self-hosted):

```typescript
await miosa.deployments.env.set(deploymentId, {
  environment: "production",
  vars: {
    QDRANT_URL: "https://your-cluster.qdrant.io",
    QDRANT_API_KEY: "your-api-key",
  },
})
```

## Python SDK

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Provision a managed Qdrant instance
qdrant = miosa.databases.create(
    name="my-rag-db",
    engine="qdrant",
    size="small",
)
print(qdrant["id"])   # db_...

# Get connection credentials
creds = miosa.databases.credentials(qdrant["id"])
print(creds["url"])       # https://qdrant.proj_xxx.miosa.internal
print(creds["api_key"])

# Teardown
miosa.databases.delete(qdrant["id"])
```

# Redis / Cache

URL: https://miosa.ai/docs/data/redis
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/redis
Source: src/routes/docs/data/redis/+page.md
Description: Managed Redis per project for caching, sessions, and pub/sub.

Managed Redis is live.
Per-project instances and `REDIS_URL` injection are available.
Redis is provisioned or attached explicitly and should not be assumed to exist in every sandbox template.

## What you get

Per project: a managed Redis instance, with credentials injected as `REDIS_URL`:
```

REDIS_URL=redis://default:pass@host:port/0
```

Standard Redis clients work without modification:
```typescript

const redis = createClient({ url: process.env.REDIS_URL })
await redis.connect()

await redis.set("user:123:last-seen", new Date().toISOString())
const value = await redis.get("user:123:last-seen")
```

## Use cases

- **Cache**  -  short-lived computed results.
- **Sessions**  -  express-session / Phoenix sessions / similar.
- **Pub/sub**  -  agent coordination, real-time fan-out.
- **Rate limiting**  -  atomic INCR + TTL.
- **Job queues**  -  Bull, BullMQ, Sidekiq, Oban-light alternatives.

For full job-queue workloads at scale, MIOSA has a [Background Jobs](/docs/docker-host/runtime-instances/) primitive that's a better fit than rolling your own on Redis.

## Provision
```typescript
await miosa.projects.dataServices.create(projectId, {
  type: "redis",
  size: "small",  // small | medium | large
})
```

## Limits and durability

Memory, connection, and persistence settings depend on the returned managed-database plan.
Inspect the database response and metrics for the selected instance.
Treat Redis as cache-class unless the selected plan explicitly guarantees the durability required by your application.

## Pub/sub considerations

If you're using Redis pub/sub for cross-runtime coordination, multiple runtime instances of the same service can all subscribe  -  MIOSA does not deduplicate or proxy pub/sub. For higher-volume real-time fan-out, consider SSE through MIOSA's [Events](/docs/api-reference/events/) or a dedicated message broker.

## Bring your own Redis?

Yes. Set `REDIS_URL` as an env var to whatever external Redis you prefer (Upstash, AWS ElastiCache, your own).

# Storage / Buckets

URL: https://miosa.ai/docs/data/storage
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/storage
Source: src/routes/docs/data/storage/+page.md
Description: Per-project object storage with signed-URL uploads and downloads.

Object storage is shipped. Buckets, objects, presigned URL (upload and download), quota enforcement, and per-tenant isolation are all live. Large direct uploads (&gt;5 MB) should use the presigned path; see the limits table below.

## What you get

Per project: an S3-compatible bucket, accessed through MIOSA endpoints. Credentials injected as env vars:
```

STORAGE_BUCKET=miosa-proj_xxx-uploads
STORAGE_ENDPOINT=https://storage.miosa.app
STORAGE_KEY_ID=...
STORAGE_KEY_SECRET=...
```

Your code uses the standard S3 client libraries:
```typescript

const s3 = new S3Client({
  endpoint: process.env.STORAGE_ENDPOINT,
  credentials: {
    accessKeyId: process.env.STORAGE_KEY_ID!,
    secretAccessKey: process.env.STORAGE_KEY_SECRET!,
  },
  region: "us-east-1",
})

await s3.send(new PutObjectCommand({
  Bucket: process.env.STORAGE_BUCKET,
  Key: "uploads/foo.png",
  Body: pngBuffer,
}))
```

## Use it your way: API, CLI, or SDK

No SDK required. Same bucket, three ways.

> Storage calls need an API key with the `storage:read` / `storage:write` scope. Mint one with `POST /api/v1/api-keys {"scopes": ["storage:read","storage:write"]}`. A plain key gets a 403 telling you which scope is missing.

**Raw API (curl):**
```bash
# Create a bucket
curl -X POST https://api.miosa.ai/api/v1/storage/buckets \
  -H "Authorization: Bearer $MIOSA_API_KEY" -H "Content-Type: application/json" \
  -d '{"name": "my-bucket"}'

# Upload an object (binary → application/octet-stream)
curl -X PUT "https://api.miosa.ai/api/v1/storage/buckets/BUCKET_ID/objects/path/file.txt" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/octet-stream" --data-binary @file.txt

# Download it
curl "https://api.miosa.ai/api/v1/storage/buckets/BUCKET_ID/objects/path/file.txt" \
  -H "Authorization: Bearer $MIOSA_API_KEY"

# Presign a URL so a browser can upload/download directly (no proxy)
curl -X POST "https://api.miosa.ai/api/v1/storage/buckets/BUCKET_ID/presign" \
  -H "Authorization: Bearer $MIOSA_API_KEY" -H "Content-Type: application/json" \
  -d '{"key": "path/file.txt", "method": "GET"}'
```

**CLI:**
```bash
miosa storage create my-bucket
miosa storage list
miosa storage objects <bucket-id>
```

Upload, download and presigning have no dedicated subcommand; drive them with `miosa api`:

```bash
# Upload an object
miosa api PUT /storage/buckets/<bucket-id>/objects/path/file.txt \
  -H "Content-Type: application/octet-stream" -d @./file.txt

# Download it
miosa api GET /storage/buckets/<bucket-id>/objects/path/file.txt

# Presign a URL so a browser can upload/download directly (no proxy)
miosa api POST /storage/buckets/<bucket-id>/presign \
  -d '{"key": "path/file.txt", "method": "GET"}'
```

## Signed URLs for browser uploads

Don't proxy file uploads through your runtime. Mint a signed URL server-side; the browser uploads directly to storage:
```typescript
// Server
const url = await miosa.storage.signedUrl({
  bucket: process.env.STORAGE_BUCKET!,
  key: `users/${userId}/avatar.png`,
  operation: "put",
  expiresInSec: 300,
  contentType: "image/png",
})
return { uploadUrl: url }
```
```typescript
// Browser
await fetch(uploadUrl, {
  method: "PUT",
  body: file,
  headers: { "Content-Type": "image/png" },
})
```

Same pattern for downloads (`operation: "get"`). Signed URLs are scoped (single key, single operation, short expiry)  -  no risk of leaking bucket-wide credentials to a browser.

## Public vs private

Each object can be private (default; access only via signed URL) or public (served from a `*.storage.miosa.app` URL). Public objects can also be fronted by a custom domain via your project's [Domain](/docs/docker-host/domains/) settings.

## Bandwidth and storage costs

Two billable dimensions:

- **Storage**  -  GB-month for stored bytes.
- **Egress**  -  GB out from MIOSA to the public internet. Storage-to-runtime within MIOSA is free.

[Attribution](/docs/platform/attribution/) is carried on every event for chargeback.

## Limits

| Limit | Default | Tunable |
|---|---|---|
| Storage per project | 1 GB | Yes (plan-dependent) |
| Direct API upload size | 5 MB verified | Larger uploads should use presigned/direct storage |
| Max object size | 5 GB target | Up to 100 GB target for multipart |
| List keys per call | 1000 | Standard S3 pagination |

The latest live storage smoke on June 9, 2026 verified create, upload,
download, SHA-256 validation, and cleanup through `10 / 10` sequential `5 MB`
objects. `8 MB` and `10 MB` direct raw uploads currently fail before storage, so
large files should use presigned URLs or S3-compatible direct upload flows until
the streaming API path is promoted. See [Benchmarks](/docs/benchmarks/) for the
measured table and the ComputeSDK storage comparison.

## Sandboxes can use the bucket too

The same env vars are injected into sandboxes for dev / testing. Upload from inside a sandbox:
```typescript
await sandbox.exec({
  cmd: "aws",
  args: ["s3", "cp", "/workspace/build.tar.gz", `s3://${process.env.STORAGE_BUCKET}/builds/`],
  env: {
    AWS_ACCESS_KEY_ID: process.env.STORAGE_KEY_ID,
    AWS_SECRET_ACCESS_KEY: process.env.STORAGE_KEY_SECRET,
    AWS_ENDPOINT_URL: process.env.STORAGE_ENDPOINT,
  },
})
```

## Bring your own bucket?

Yes. Set the env vars to point at an external S3-compatible bucket (real AWS, Backblaze B2, R2, etc.). MIOSA injects whatever you set.

## Python SDK

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Create a bucket
bucket = miosa.storage.create_bucket("my-uploads", public=False)
bucket_id = bucket["id"]

# Upload bytes
with open("report.pdf", "rb") as f:
    miosa.storage.put_object(bucket_id, "reports/report.pdf", f.read(),
                             content_type="application/pdf")

# Mint a presigned URL for browser upload (PUT)
presigned = miosa.storage.presign(
    bucket_id,
    key="avatars/user-123.png",
    operation="put",
    expires_in_sec=300,
    content_type="image/png",
)
print(presigned["url"])

# Mint a presigned URL for browser download (GET)
download = miosa.storage.presign(
    bucket_id,
    key="reports/report.pdf",
    operation="get",
    expires_in_sec=3600,
)
print(download["url"])

# List objects with a prefix
objects = miosa.storage.list_objects(bucket_id, prefix="reports/")
for obj in objects:
    print(obj["key"], obj["size"])

# Delete a bucket
miosa.storage.delete_bucket(bucket_id)
```

# Volumes

URL: https://miosa.ai/docs/data/volumes
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/data/volumes
Source: src/routes/docs/data/volumes/+page.md
Description: Persistent block storage attached to a runtime instance. State that doesn't fit in Postgres.

Volumes are live.
Create a persistent block device, attach it to a compatible computer on the same host, and preserve writes independently of the computer lifecycle.
Attachment to a replacement computer is explicit.
Most workloads should use [Postgres](/docs/data/postgres/) or [Storage](/docs/data/storage/) because local volumes are host-bound.

A **Volume** is a persistent block device attached to a compatible computer.
It survives ordinary computer restarts while the host-local volume remains healthy.
It does not automatically move across hosts.
Useful cases include:

- SQLite databases that need to be local to the runtime.
- Caches you can't afford to lose on restart.
- LLM model weights downloaded once and shared across instances.
- Workloads that legitimately need filesystem state (not just key-value).

Volumes are NOT useful for:

- Stateful databases  -  use [Postgres](/docs/data/postgres/) instead. It scales better, backs up automatically, and survives host failures.
- User-uploaded files  -  use [Storage / Buckets](/docs/data/storage/). Cheaper, browser-uploadable, geo-replicable.
- Shared state across multiple replicas  -  volumes are typically attached to ONE runtime instance.

## Create

```typescript
await miosa.projects.dataServices.create(projectId, {
  type: "volume",
  name: "model-weights",
  sizeGb: 50,
})
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Create a 50 GB volume
vol = miosa.volumes.create(name="model-weights", size_gb=50)
print(vol["id"])  # vol_...

# List all volumes
for v in miosa.volumes.list():
    print(v["name"], v["size_gb"], "GB")

# Delete a volume
miosa.volumes.delete(vol["id"])
```

## Use it your way: API, CLI, or SDK

No SDK required.

**Raw API (curl):** the raw API takes `size_bytes` and a `backend` (use `local`).
```bash
# Create a 50 GB volume
curl -X POST https://api.miosa.ai/api/v1/volumes \
  -H "Authorization: Bearer $MIOSA_API_KEY" -H "Content-Type: application/json" \
  -d '{"name": "model-weights", "size_bytes": 53687091200, "backend": "local"}'

# Attach it to a running computer at a mount path
curl -X POST https://api.miosa.ai/api/v1/computers/COMPUTER_ID/volumes \
  -H "Authorization: Bearer $MIOSA_API_KEY" -H "Content-Type: application/json" \
  -d '{"volume_id": "VOL_ID", "mount_path": "/mnt/data"}'

# Detach (by attachment id)
curl -X DELETE https://api.miosa.ai/api/v1/computers/COMPUTER_ID/volumes/ATTACHMENT_ID \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

**CLI:**
```bash
miosa volume create model-weights --size-gb 50
miosa volume list
```

Attach and detach are per-computer; drive them with `miosa api`:

```bash
# Attach the volume to a running computer at a mount path
miosa api POST /computers/<computer-id>/volumes \
  -d '{"volume_id": "<volume-id>", "mount_path": "/mnt/data"}'

# Detach by attachment id
miosa api DELETE /computers/<computer-id>/volumes/<attachment-id>
```

Delete a volume (it must be detached first):

```bash
miosa volume rm <volume-id>
```

> A local-backend volume lives on one host, so it attaches to computers on that same host. Cross-host attach returns a clear error rather than failing silently.

## Mount

A volume is mounted into the runtime instance's filesystem at a path:
```typescript
await miosa.services.update(serviceId, {
  volumes: [
    { dataServiceId: volumeId, mountPath: "/var/models" },
  ],
})
```

At boot, `/var/models` is the volume's contents. Writes persist.

## Replicas and volumes

Most volumes attach to a single runtime instance. If you scale a service to N replicas, by default each replica gets the **same volume mount** if it's marked `shared: true`, or its own volume if `shared: false`.

Shared volumes have all the usual concurrency caveats (filesystem locks, file-corruption risk if multiple writers touch the same file). Use Postgres for shared state unless you really know what you're doing.

## Limits

| Limit | Default |
|---|---|
| Max volume size | 500 GB |
| Max volumes per project | 10 |
| Filesystem | ext4 |
| Host placement | Must match the computer host |

## When to use a volume

Realistic short list:

1. You're shipping a self-hosted SQLite-backed app to keep deployment simple.
2. You're running an LLM inference service and don't want to re-download model weights on every instance start.
3. You have a writable filesystem cache that's expensive to rebuild.

Anything else, use Postgres or Storage.

# Files & Exec

URL: https://miosa.ai/docs/develop/files-and-exec
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/files-and-exec
Source: src/routes/docs/develop/files-and-exec/+page.md
Description: Read, write, watch files inside a sandbox. Run commands, stream stdout/stderr, manage processes.

# Files & Exec

The Files and Exec APIs are how you (or an AI agent) interact with a Sandbox. Together they're the substrate for everything else: generating code, running builds, starting servers.

## Files

### Write

```typescript
await sandbox.files.write("/workspace/src/index.ts", `
  console.log("Hello from MIOSA")
`)

// Binary
await sandbox.files.write("/workspace/logo.png", pngBuffer, {
  encoding: "binary",
})
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/files/write \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{
    "path": "/workspace/src/index.ts",
    "content": "console.log(\"Hello from MIOSA\")"
  }'
```

Parent directories are created as needed. Existing files are overwritten.

### Read
```typescript
const content = await sandbox.files.read("/workspace/package.json")
const parsed = JSON.parse(content)
```
```bash
curl https://api.miosa.ai/api/v1/sandboxes/$SBX/files/read?path=/workspace/package.json \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

### Export generated artifacts

Use exports when an agent creates files that a user should download from your
product: HTML, PDFs, CSVs, ZIPs, screenshots, reports, or build folders.

```typescript
const exportInfo = await sandbox.createExport({
  paths: ["/workspace/dist/index.html", "/workspace/dist/assets/app.js"],
  label: "homepage build",
})

console.log(exportInfo.archiveDownloadUrl)

const archive = await sandbox.downloadExport([
  "/workspace/dist/index.html",
  "/workspace/dist/assets/app.js",
])
```

```python
export_info = sandbox.create_export(
    ["/workspace/dist/index.html", "/workspace/dist/assets/app.js"],
    label="homepage build",
)

print(export_info["archive_download_url"])

archive = sandbox.download_export([
    "/workspace/dist/index.html",
    "/workspace/dist/assets/app.js",
])
```

```bash
miosa files cp sb_abc123:/workspace/dist/index.html ./index.html --json

miosa files cp -r sb_abc123:/workspace/dist ./homepage-build --json
```

For one file, exports return a direct download URL for that file. For multiple
files, exports return an archive download URL. This is the same low-level model
as copying or downloading sandbox files: the sandbox remains the working
filesystem, and your product decides which paths become user-visible artifacts.

Use this pattern for artifact products:

```text
1. Agent writes files under /workspace/artifacts or /workspace/dist.
2. Your backend calls createExport with the exact paths users should receive.
3. Your UI stores the returned export descriptor on the task or run.
4. User clicks Download.
5. Your backend streams the direct file or tar archive from MIOSA.
```

Examples:

| Agent output | Export path |
|---|---|
| Landing page HTML | `/workspace/dist/index.html` |
| Built app folder | `/workspace/dist` |
| PDF report | `/workspace/artifacts/report.pdf` |
| Sales CSV | `/workspace/artifacts/leads.csv` |
| Screenshot set | `/workspace/artifacts/screenshots` |
| Generated project | `/workspace` or a filtered build folder |

Do not make users scrape files out of terminal output. If a run produces a
deliverable, turn it into an export and attach it to the run, task, or project
record in your product.

For agent platforms, treat the sandbox filesystem as the working surface and
exports as the user-facing contract. The agent can create many intermediate
files under `/workspace`, but your backend should promote only approved paths
into named artifacts.

| Product pattern | Working paths | Exported artifact |
|---|---|---|
| Lovable/Replit/Genspark-style app builder | `/workspace`, `/workspace/dist` | source ZIP, build folder, preview, deployment URL |
| Polsia-style operator | `/workspace/research`, `/workspace/artifacts` | reports, CSVs, campaign copy, generated app bundles |
| cofounder.co-style company OS | `/workspace/agents`, `/workspace/receipts`, `/workspace/artifacts` | milestone documents, decisions, status reports |
| Nebula-style virtual device | shared `/workspace` plus computer screenshots | selected files, screenshots, logs, device receipts |

Store the export id, label, paths, size, MIME type when available, and download
URL on your own run record. That gives users a stable artifact history even if
the sandbox later pauses, forks, or continues generating new files.

### List
```typescript
const entries = await sandbox.files.list("/workspace")
for (const e of entries) {
  console.log(e.type, e.path, e.size)
}
```
```bash
curl https://api.miosa.ai/api/v1/sandboxes/$SBX/files/list?path=/workspace \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

### Watch

Stream filesystem events:
```typescript
for await (const event of sandbox.files.watch("/workspace")) {
  console.log(event.type, event.path)
  // event.type: "create" | "modify" | "delete"
}
```

Watch is implemented as Server-Sent Events. See [Events](/docs/api-reference/events/) for the SSE event shape.

### Filesystem layout

| Path | Purpose |
|---|---|
| `/workspace` | Working directory; this is where agents write app code |
| `/home/sandbox` | User home |
| `/tmp` | Temporary scratch (cleared on sandbox destroy) |
| `/opt/venv` | Pre-installed Python virtualenv (`miosa-sandbox` and Python templates) |
| `/usr/local/bin` | System binaries |

Generally, write inside `/workspace` and let your build tooling handle
node_modules, virtualenvs, etc. Production publish freezes `/workspace`
(excluding cache dirs) as the source snapshot. See
[Publishing](/docs/docker-host/publishing/).

## Exec

Run commands inside the sandbox.

### One-shot

```typescript
const result = await sandbox.exec("npm install", {
  cwd: "/workspace",
  env: { NODE_ENV: "development" },
  timeoutSec: 120,
})

console.log(result.exit_code, result.stdout, result.stderr)
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/exec \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{
    "cmd": "npm",
    "args": ["install"],
    "cwd": "/workspace",
    "timeout_ms": 120000
  }'
```

Blocks until the command exits (or `timeoutMs` elapses). Returns `exit_code`, `stdout`, `stderr`, and `duration_ms`.

### Long-running servers
```typescript
// Keep the process attached and consume its output as it runs.
const events = sandbox.exec.stream("node /workspace/server.js")
for await (const event of events) console.log(event)
```

Use [Previews](/docs/develop/previews/) to expose its port.

### Streaming

For real-time stdout/stderr (e.g. tail an agent's compile output):
```typescript
for await (const chunk of sandbox.exec.stream("pnpm dev")) {
  if (chunk.type === "stdout") process.stdout.write(chunk.data)
  if (chunk.type === "stderr") process.stderr.write(chunk.data)
  if (chunk.type === "exit") console.log("exit:", chunk.exit_code)
}
```

Implemented as SSE. See [Streaming Exec](/docs/api-reference/streaming-exec/).

### Terminal

Need an interactive PTY (for remote dev or AI agents driving CLIs)?
```typescript
const session = await sandbox.terminal.create({})
// Attach over the session's WebSocket channel. See API Reference: Terminal for the protocol.
```

Terminals are WebSocket-based with `xterm.js`-compatible ANSI passthrough. See [API Reference: Terminal](/docs/api-reference/streaming-exec/) for protocol details.

## Process management

`exec` blocks until the command exits; `exec.stream` keeps it running while you consume output. To inspect or stop processes, run the shell commands inside the sandbox:

```typescript
await sandbox.exec("ps aux")
await sandbox.exec("kill <pid>")
```

## Idempotency

Exec is **not** idempotent. Running `npm install` twice runs it twice. If you
need idempotent retries, store a marker file:
```typescript
const marker = "/workspace/.deps-installed"
const exists = await sandbox.files.exists(marker)
if (!exists) {
  await sandbox.exec("npm ci")
  await sandbox.files.write(marker, new Date().toISOString())
}
```

File writes are idempotent: same path, same content, same result.

## Limits

| Limit | Default | Tunable |
|---|---|---|
| Max file size per write | 500 MB | Yes (plan-dependent) |
| Max files per sandbox | 1,000,000 | Yes |
| Max exec stdout buffer | 10 MB | Stream mode bypasses this |
| Max exec duration | `timeout_ms` parameter, default 30 s; pass `120000` for npm/pip installs | Yes; detached has no limit |
| Max concurrent detached jobs | 100 | Yes |

`cmd` and `args` are passed as a tuple to `execve` directly, with no shell
interpolation. You don't need to quote arguments or escape special characters.
If you actually want a shell, set `cmd: "bash"` and
`args: ["-c", "&lt;your shell command&gt;"]`.

# Previews

URL: https://miosa.ai/docs/develop/previews
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/previews
Source: src/routes/docs/develop/previews/+page.md
Description: Live URLs that proxy into a sandbox port. Public, private, embeddable, share-tokenized.

# Previews

A **Preview** is a URL that routes to a port inside a running Sandbox. The agent writes code, starts a dev server, the preview updates live in the browser. This is the build loop of AI app builders.

## Quick create

```typescript
// Make sure something is listening on the port first
const preview = await sandbox.previews.create({
  port: 3000,
  visibility: "private",   // or "public"
})

console.log(preview.url)
// → https://3000-abc12345.sandbox.miosa.ai
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/previews \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{"port":3000,"visibility":"private"}'
```

The URL follows the pattern `https://{port}-{slug}.sandbox.miosa.ai` where `{slug}` is the first 8 characters of the sandbox UUID. For the template default port, the URL is `https://{slug}.sandbox.miosa.ai` (no port prefix). For white-label platforms, this can be `https://{port}-{slug}.sandbox.{your-domain}` once DNS delegation is set up.

## Visibility

| Mode | Access |
|---|---|
| `public` | Anyone with the URL can view (and is rate-limited by IP). No auth required. |
| `private` | Requires either an authenticated MIOSA session OR a valid share token. |

For most white-label use cases, **always use `private`**. Then mint a share token to hand to the end user's browser.

## Share tokens

A share token is a short-lived, scoped credential that lets a specific browser access a private preview without exposing your MIOSA workspace API key.

```typescript
const share = await sandbox.previews.share(preview.id, {
  expiresInSec: 3600,  // 1 hour default; max varies by plan
})

console.log(share.share_url)
// → https://3000-abc12345.sandbox.miosa.ai?preview_token=<one-time raw token>

// In your end-user's frontend:
//   <iframe src={shareUrl} sandbox="allow-same-origin allow-scripts" />
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/previews/$PREVIEW/share \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{"ttl_seconds": 3600}'
```

Response:
```json
{
  "data": {
    "id": "preview_...",
    "share_token_prefix": "first12chars",
    "share_token_expires_at": "2026-05-14T19:30:00Z"
  },
  "preview_token": "miosa_pv_<one-time-raw-token>",
  "share_url": "https://3000-abc12345.sandbox.miosa.ai?preview_token=miosa_pv_<one-time-raw-token>"
}
```

The raw `preview_token` value is only in the create-share response. Persist it server-side if you need to re-display, or re-mint a new one. Subsequent reads of the preview return only the `share_token_prefix` (for matching to log entries) and the expiry timestamp.

The token can be passed two ways:
- As `?preview_token=...` query string in the URL (most common; works for iframes).
- As `x-miosa-preview-token: &lt;token&gt;` HTTP header (when you control the request).

MIOSA's proxy strips the credential before forwarding to your sandbox app  -  your app never sees the token. The proxy authenticates the request, then forwards a clean HTTP request to your dev server on the sandbox.

## Iframe embedding

Previews are designed to be embedded in iframes:
```html
<iframe src="https://3000-abc12345.sandbox.miosa.ai?preview_token=miosa_pv_..."
        sandbox="allow-same-origin allow-scripts allow-forms"
        style="width:100%; height:600px; border:0;"></iframe>
```

The preview proxy emits CSP `frame-ancestors` for `*.sandbox.miosa.ai`, `*.miosa.ai`, and `localhost:4000` by default. For white-label embedding into your own domain, contact support  -  the production proxy CSP is configurable per tenant.

    P->>S: proxy request to port 3000
    S-->>P: HTTP response
    P-->>B: response (token stripped)

## Lifecycle

- `active` while the underlying sandbox is running and the preview hasn't been explicitly deleted.
- `expired` once the share token TTL (if set) elapses.
- `deleted` when you delete it, or automatically a short time after the sandbox is destroyed.

Re-creating a preview on the same port returns a new preview record with a new slug. Old preview URLs do not automatically transfer.

## Preview vs Deployment URL

| | Preview | Deployment URL |
|---|---|---|
| What it points at | A live sandbox port | An immutable deployment version |
| Updates live? | Yes  -  sandbox edits reflect immediately | No  -  only changes on rollback / re-promote |
| Lifetime | Tied to the sandbox | Persistent |
| Use it for | Build loop, sharing in-progress work | Production traffic |

You don't promote a preview to a deployment. You publish from a sandbox (which produces a deployment version with its own URL). The preview keeps living until the sandbox dies.

## Abuse limits

Public previews are aggressively rate-limited by IP at the edge. Private previews are rate-limited per share token. If you're embedding into a high-traffic site, use a custom domain and a dedicated tenant plan  -  preview hosts are not designed to serve production traffic.

## Why preview tokens exist

Sandbox previews are live HTTP services running inside isolated VMs. To embed one in your product UI, the browser needs to make an authenticated request to the MIOSA preview proxy.

The wrong approach - passing your API key to the browser - would let any user call the MIOSA API as your account. Preview tokens are the correct boundary: scoped to one sandbox, one port, and a short TTL.

  MiosaAPI-->>YourBackend: { share_url, token }
  YourBackend-->>Browser: { embed_url: share_url, expires_in: 3600 }
  Browser->>PreviewProxy: iframe src = share_url (token in URL)
  PreviewProxy-->>Browser: proxied sandbox content

## Server-side mint flow

```python
from miosa import Miosa

client = Miosa(api_key="msk_u_...")

# 1. Get or create a preview record for the port your app listens on.
previews = client.sandboxes.get("sbx_abc123").preview.list()
preview = next((p for p in previews if p["port"] == 3000), None)
if not preview:
    preview = client.sandboxes.get("sbx_abc123").preview.create(port=3000)

# 2. Mint a time-limited share token.
share = client.sandboxes.get("sbx_abc123").preview.share(
    preview["id"],
    ttl_seconds=3600,
)

embed_url = share["share_url"]   # pass this to the browser
```

```typescript

const client = new Miosa({ apiKey: "msk_u_..." });

// 1. Get or create a preview record for the port your app listens on.
const previews = await client.sandboxes.preview.list("sbx_abc123");
let preview = previews.find((p) => p.port === 3000);
if (!preview) {
  preview = await client.sandboxes.preview.create("sbx_abc123", { port: 3000 });
}

// 2. Mint a time-limited share token.
const share = await client.sandboxes.preview.share("sbx_abc123", preview.id, {
  ttlSeconds: 3600,
});

const embedUrl = share.shareUrl; // pass this to the browser
```

### TTL strategy

| Use case | Recommended TTL |
|---|---|
| Interactive work session | 3 600 s (1 hour) - refresh when the user returns |
| Short demo or share link | 900 s (15 minutes) |
| Public share with explicit expiry | Up to 86 400 s (24 hours) |
| Permanent share | No TTL - use `sandbox.share.create()` with no expiry, manage revocation manually |

When a token expires, the iframe shows a "session expired" message from the preview proxy. Your UI should catch the `message` event from the iframe and re-mint a token transparently.

### Iframe sandbox flags

```html
<iframe
  src="https://preview.example.com/p/sbx_abc123?preview_token=miosa_pv_..."
  allow="clipboard-read; clipboard-write"
  sandbox="allow-scripts allow-same-origin allow-forms allow-popups"
  style="width: 100%; height: 600px; border: none;"
  title="Design workspace"
></iframe>
```

| Flag | Required? | Reason |
|---|---|---|
| `allow-scripts` | Yes | Preview content runs JavaScript. |
| `allow-same-origin` | Yes | Lets the preview proxy set session cookies. |
| `allow-forms` | Recommended | Many sandbox apps submit forms. |
| `allow-popups` | Optional | Only if your sandbox app opens new windows. |
| `allow-downloads` | Optional | Only if your sandbox app serves file downloads. |

Do not add `allow-top-navigation` - it would let sandbox content redirect your top-level page.

### Token refresh

Detect expiry by listening for the `message` event from the iframe:

```javascript
window.addEventListener("message", async (event) => {
  // The preview proxy emits this message when the token expires.
  if (event.data?.type === "miosa:preview:expired") {
    const res = await fetch(`/api/embed-url?sandbox_id=${sandboxId}`);
    const { embed_url } = await res.json();
    document.getElementById("sandbox-frame").src = embed_url;
  }
});
```

### Permission scoping

When you mint a token for an end user, scope it to the minimum permissions they need:

```python
token = client.browser_tokens.create(
    workspace_id="550e8400-...",
    project_id="660e8400-...",
    external_user_id="user_42",
    permissions=["sandbox:read", "preview:read"],
    ttl_seconds=3600,
)
```

```typescript
const token = await client.browserTokens.create({
  workspaceId: "550e8400-...",
  projectId: "660e8400-...",
  externalUserId: "user_42",
  permissions: ["sandbox:read", "preview:read"],
  ttlSeconds: 3600,
});
```

Available permission scopes:

| Scope | Grants |
|---|---|
| `sandbox:read` | Read sandbox metadata and state |
| `sandbox:exec` | Run commands inside the sandbox |
| `preview:read` | Embed and view previews |
| `preview:share` | Create public share links |
| `files:read` | Read the sandbox filesystem |
| `files:write` | Write files to the sandbox |

Admin-scoped tokens can delete sandboxes and modify configuration. Reserve those operations for your server-side API key.

### Early revocation

Revoke a preview token before it expires - for example, when a user logs out or loses access:

```python
client.sandboxes.get("sbx_abc123").preview.revoke_share(preview_id="prev_xyz")
```

```typescript
await client.sandboxes.preview.revokeShare("sbx_abc123", "prev_xyz");
```

# Sandbox shares

URL: https://miosa.ai/docs/develop/sandbox-shares
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandbox-shares
Source: src/routes/docs/develop/sandbox-shares/+page.md
Description: Create a public, read-only link to a running sandbox so a teammate or an outside user can view it, and revoke the link at any time.

# Sandbox shares

A **share** is a publicly accessible URL that gives read-only access to a running sandbox. Unlike a preview token, a share URL is not scoped to an iframe and the recipient does not need any credentials: the token is embedded in the URL.

```text
https://{sandbox-id}.sandboxes.miosa.ai?ms=ms_<token>
```

A share is view-only. The recipient can watch, not drive. Revoke a share and the link stops working immediately, returning `403` to anyone still holding it.

## Create a share

```python
share = client.sandboxes.shares.create("sbx_abc123", expires_in=86400)
print(share.share_url)
```

```typescript
const share = await client.sandboxes.shares.create('sbx_abc123', { expiresIn: 86400 });
console.log(share.shareUrl);
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/shares \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"expires_in": 86400}'
```

| Field | Type | Default | Description |
|---|---|---|---|
| `expires_in` | integer | `3600` | TTL in seconds |
| `scope` | string | `"read"` | The only supported value |

The response includes `share_id` (used to revoke), `share_url` (safe to distribute), `expires_at`, and `scope`.

## List and revoke

```python
for s in client.sandboxes.shares.list("sbx_abc123"):
    print(s.share_id, s.expires_at)

client.sandboxes.shares.delete("sbx_abc123", share.share_id)
```

```bash
curl https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/shares \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl -X DELETE https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/shares/shr_01hx9m7n3k \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Listing returns only active shares  -  non-revoked and not yet expired. Revoking returns `204 No Content`.

## Shares, previews, and browser tokens

Three different ways to hand someone access, for three different jobs:

| Mechanism | Access | Use it to |
|---|---|---|
| Sandbox share | Read-only view of a running sandbox | Let someone watch a sandbox from a normal link |
| Preview token | HTTP access to one exposed port | Embed a running app in an iframe |
| Browser access token | A live desktop stream | Embed a desktop for one end-user |

See [Previews](/docs/develop/previews/) for ports and [Browser access tokens](/docs/platform/browser-tokens/) for desktop embeds.


    Wire format, error codes, and every endpoint.

# Sandboxes

URL: https://miosa.ai/docs/develop/sandboxes
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes
Source: src/routes/docs/develop/sandboxes/+page.md
Description: Fast, isolated Linux VMs for code execution, builds, tests, and dev servers, with live preview URLs and snapshots.

# Sandboxes

A **Sandbox** is MIOSA's fast code execution environment.
Your agent writes files into it, executes commands, exposes ports as live preview URLs, and snapshots state for branching or rollback.
Use it for build loops, tests, scripts, package installs, code generation, preview servers, and short-lived automation.

Sandboxes are persistent by default, which means they survive a stop.
When you stop one or its timeout expires, MIOSA preserves the disk and moves the sandbox to `stopped` so it can resume later.
Running processes do not survive a stop.
Persistent does not mean the sandbox survives the loss of its host; see [Sandbox lifecycle](/docs/develop/sandboxes/lifecycle/).
SOMA does not support persistence yet.
Destroy only when the saved state should be removed.

## 1. Create a sandbox

```bash
miosa create my-box --wait     # provision a sandbox and wait until it is ready
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const sandbox = await miosa.sandboxes.create()
console.log(sandbox.id, sandbox.state)
// sbx_a1b2c3d4e5  running
```

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sandbox = miosa.sandboxes.create()
print(sandbox.id, sandbox.state)
# sbx_a1b2c3d4e5  running
```

## 2. Run a command

```bash
miosa exec my-box -- echo "hello from MIOSA"
```

```typescript
const result = await sandbox.exec("echo hello from MIOSA")
console.log(result.stdout)
// hello from MIOSA
```

```python
result = sandbox.exec("echo hello from MIOSA")
print(result.stdout)
# hello from MIOSA
```

## 3. Write a file and open a preview

```bash
echo "<h1>Hello</h1>" | miosa files write my-box:/workspace/index.html
miosa preview create my-box 3000 --visibility public
```

```typescript
await sandbox.files.write("/workspace/index.html", "<h1>Hello</h1>")
const preview = await sandbox.previews.create(3000)
console.log(preview.url)
// https://3000-abc12345.sandbox.miosa.ai
```

```python
sandbox.files.write("/workspace/index.html", "<h1>Hello</h1>")
preview = sandbox.previews.create(port=3000)
print(preview.url)
# https://5173-abc12345.sandbox.miosa.ai
```

Open the preview URL MIOSA returns. Only the port you exposed is reachable, and only through the MIOSA proxy.

Use a Sandbox for code and processes.
Use a [Computer](/docs/computers/overview/) for a visible GUI, browser login, or human takeover.
Use [Docker Host](/docs/docker-host/docker-deploy/) when the result should be a durable 24/7 deployment URL with custom domains.
Every sandbox boots the same main image, which ships Docker with the `docker compose` and `docker buildx` plugins, and a live browser with CDP on a virtual display (`Xvfb :99`), so you can build and run containers, and drive a browser, while you develop.
A SOMA sandbox does not have that display yet, so the live viewer is not available there.

## Image, template, and runtime

Three different things decide what a sandbox boots with, and they are not the same choice.

| | What it is | Where you set it |
|---|---|---|
| **Image** | The one main image, with Node, Python, Docker Engine 29.9 with Compose and Buildx, a live browser with CDP, and the code interpreter already inside. | Nothing to choose: every sandbox boots it. |
| **Template** | Optional content staged inside that image at create time: files, a scaffold, packages, and the start command. | `template_id`, for example `nextjs`, `static-html`, or a custom template. |
| **Runtime** | Which virtual machine monitor runs the sandbox. | `runtime`: `firecracker` (the default), `soma`, or `auto`. |

A template is never a separate image.
An older image id passed as `template_id` still works and boots the main image; see the [Sandbox Templates API](/docs/api-reference/sandbox-templates/).
See [Templates](/docs/develop/templates/) for the app starters, and [Choosing a runtime](/docs/soma/choosing-a-runtime/) for the runtime option.

## Pick what you need

| Need | Product | Result |
|---|---|---|
| Run commands, edit files, install packages, test code | **Sandbox** | Isolated runtime with exec, files, snapshots, and preview URLs |
| Use a browser login, desktop app, screenshots, mouse, keyboard | **Computer** | Durable GUI machine with streaming and desktop control |
| Publish a 24/7 app for users | **Docker Host** | Always-on deployment URL with custom domain support |

Sandboxes are excellent for building and previewing.
They are not the final production hosting layer.
When a preview becomes a user-facing app, publish it through Docker Host so it gets the right routing, domains, lifecycle, and billing behavior.

Description: What sandboxes are for, what a sandbox is concretely, and the core exec, files, preview, snapshot, and lifecycle capabilities.

# Capabilities

This page is the reference behind the [Sandboxes overview](/docs/develop/sandboxes/): what people build with sandboxes, what one actually is, and the capabilities every sandbox exposes.

## What Sandboxes are for


    Generate code, edit files, install dependencies, run tests, and stream logs back to the agent.


    Run a web server in the sandbox and expose only the needed port as an HTTPS preview URL.


    Isolate untrusted commands from your backend while keeping filesystem state scoped to the sandbox.


    Snapshot working state, resume later, or fork from a known point for parallel agent work.


## What a Sandbox is, concretely

- Isolated compute for code generation, builds, tests, and dev servers.
- Named, versioned CPU, memory, and disk contracts plus per-sandbox timeout and environment parameters.
- `/workspace` is the editable filesystem root.
- Boots from a versioned template, usually `miosa-sandbox`.
- Persistent by default, so `timeout_sec` stops compute and preserves state instead of deleting the workspace.
- Network-isolated by default.
- Preview URLs open only the specific ports you expose.
- Destroy is permanent and removes the saved state.

## Core capabilities

| Capability | What it gives you |
|---|---|
| `exec.run` | Blocking command execution with stdout, stderr, exit code, and duration |
| `exec.stream` | Real-time stdout/stderr events for long builds or installs |
| `files.write/read/list/stat` | Direct filesystem access under `/workspace` and other allowed paths |
| `previews.create` | Public HTTPS URL for a running process on a specific sandbox port |
| `snapshot` | Durable checkpoint for resume, fork, or rollback |
| `pause` / `resume` | Stop compute without discarding saved state |

## See it work

# Connecting to a running sandbox

URL: https://miosa.ai/docs/develop/sandboxes/connect
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/connect
Source: src/routes/docs/develop/sandboxes/connect/+page.md
Description: Four ways into a live sandbox: the SDK, the CLI, SSH over an authenticated tunnel, and preview URLs. What each is good for, and what does not work.

# Connecting to a running sandbox

A sandbox has no public SSH endpoint and no open inbound port other than the ones you expose. Every way in goes through the MIOSA API and an authenticated tunnel. There are four, and they are good at different things.

SSH and TCP tunnels are advertised capabilities: confirm them on the runtime you target with `GET /api/v1/runtimes` before you depend on one. A guest cannot reach the platform's internal network; see [Internet access and egress](/docs/develop/sandboxes/internet-access/).

| Way in | Best for |
|---|---|
| SDK | Application code: run commands, stream output, move files |
| CLI | Interactive and scripted use from your terminal |
| SSH | A real `ssh` session for tools that expect one |
| Preview URL | Letting a browser reach a service running in the sandbox |

## 1. The SDK

The SDK is the path for code that talks to a sandbox. Run a command and read its output, or stream it as it runs.

```python
from miosa import Miosa

client = Miosa(api_key="msk_u_...")
sandbox = client.sandboxes.get("sbx_123")

result = sandbox.exec("uname -a")
print(result.stdout, result.exit_code)

for event in sandbox.exec_stream("pnpm install"):
    print(event.line, end="")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
const sandbox = await client.sandboxes.get('sbx_123');

const result = await sandbox.exec.run('uname -a');
console.log(result.stdout, result.exitCode);
```

Execution and file operations are covered in full in [Files and exec](/docs/develop/files-and-exec/). `exec` on a paused persistent sandbox resumes it before dispatch.

## 2. The CLI

The CLI is the fastest way to poke at a running sandbox from a terminal.

```bash
miosa exec my-box -- ls -la /workspace        # run one command, get its exit code
miosa console my-box                          # interactive PTY shell
miosa files cp ./app.py my-box:/workspace/    # move files in and out
```

- **`miosa exec`** runs a command and exits with the remote command's exit code, so it drops into scripts and CI. A sandbox that is still starting refuses commands; `exec` retries with backoff until it is ready.
- **`miosa console`** opens a full-duplex terminal over the `miosa-terminal-v1` WebSocket: a real PTY, working window resizing, and Ctrl-C reaching the remote process. Use a command after `--` to run a program instead of a login shell.
- **`miosa files`** copies, lists, and inspects files with a `<sandbox>:<path>` syntax.
- **`miosa proxy my-box 5432:5432`** forwards a local port to a sandbox port over a WebSocket tunnel for any TCP service.

See [Run commands and move files](/docs/cli/work-inside/) for the full command set.

## 3. SSH

`miosa ssh` gives you a real SSH session without any setup in `~/.ssh`. It makes a one-time key, asks the API for a short-lived certificate (15 minutes, valid for that one sandbox), and runs the system `ssh` through MIOSA's authenticated tunnel. Where the server has no certificate authority, it authorizes the one-time key in the sandbox instead. The key, certificate, and host file live in a private temporary directory that is removed when ssh ends.

```bash
miosa ssh my-box                                  # interactive login shell
miosa ssh my-box -- bash -lc "cd app && npm test"  # run a command
miosa ssh my-box -- bash -s < ./setup.sh           # pipe a script in
```

Standard input is piped through. With `ssh` or `ssh-keygen` unavailable, or with `--api`, the command runs over the API instead.

`ssh user@host` and `scp` pointed straight at a sandbox do not work. The tunnel is the only SSH path. It is also available to code: the Go SDK exposes `sandboxssh.Dial`, and the Python SDK ships `miosa.ssh_tunnel` as an OpenSSH `ProxyCommand` and a `paramiko` / `asyncssh` socket.

```text
# ~/.ssh/config
Host miosa
    HostName <sandbox id>
    User root
    ProxyCommand python3 -m miosa.ssh_tunnel %h
```

## 4. Preview URLs

To let a browser reach a service running inside the sandbox, expose its port as an HTTPS preview URL. Previews are the only inbound path; nothing else in the sandbox is reachable.

```bash
miosa preview create my-box 3000 --visibility public
miosa url my-box
```

Previews carry their own token model for embedding and sharing. See [Previews](/docs/develop/previews/).

## Which to use

- **Automation and applications:** the SDK.
- **You, at a terminal, right now:** `miosa console` for interactive work, `miosa exec` for scripts.
- **A tool that needs SSH:** `miosa ssh`, or the SDK's SSH tunnel from your own code.
- **A person or a browser that needs to open a page:** a preview URL.

Source: src/routes/docs/develop/sandboxes/create/+page.md
Description: Create a sandbox with the fused run endpoint or a full create, manage its lifetime in Python context managers, and connect to an existing sandbox by id or name.

# Create and connect

Two ways to get a running sandbox: the fused **run** endpoint when you want a sandbox and an immediate first command, and a full **create** when you need to provision first, write files, start a preview server, or keep the ID for a longer session.

## Fast path: create and run

For agents that need a sandbox and immediately run the first command, use the fused run endpoint. It is faster because MIOSA owns the readiness wait on the server and avoids an extra client poll loop plus a second public exec request.

```python

response = requests.post(
    "https://api.miosa.ai/api/v1/sandboxes/run",
    headers={

}
```

## Create with full options

Use full create when you need to provision the sandbox first, write files, start a preview server, attach databases, or keep the ID for a longer session.

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sbx = miosa.sandboxes.create(
    "miosa-sandbox",              # template_id (positional); default if omitted
    cpu_count=2,
    memory_mb=4096,
    disk_size_mb=10240,
    timeout_sec=3600,             # idle-anchored; resets on activity; default 3600
    env={"NODE_ENV": "production"},
    metadata={"agent_run": "abc123"},
    external_workspace_id="acme-corp",   # white-label attribution
    external_user_id="user_123",
    external_project_id="project_456",
    idempotency_key="run-2026-06-09-001",
)

print(sbx.id)
print(sbx.state)
print(sbx.ready)
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const sbx = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  cpuCount: 2,
  memoryMb: 4096,
  diskSizeMb: 10240,
  timeoutSec: 3600,
  env: { NODE_ENV: "production" },
  metadata: { agentRun: "abc123" },
  externalWorkspaceId: "acme-corp",
  externalUserId: "user_123",
  externalProjectId: "project_456",
  idempotencyKey: "run-2026-06-09-001",
});

console.log(sbx.id, sbx.state, sbx.boot_ms);
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: run-2026-06-09-001" \
  -d '{
    "template_id": "miosa-sandbox",
    "cpu_count": 2,
    "memory_mb": 4096,
    "disk_size_mb": 10240,
    "timeout_sec": 3600,
    "env": { "NODE_ENV": "production" },
    "metadata": { "agent_run": "abc123" },
    "external_workspace_id": "acme-corp",
    "external_user_id": "user_123",
    "external_project_id": "project_456"
  }'
```

The response body contains `id`, `state`, `template_id`, `size`, `resource_contract`,
`cpu_count`, `memory_mb`, and `created_at`. Save the `id`; every
subsequent call needs it.

### Context manager (auto-destroy)

The Python SDK supports `with` / `async with`; the sandbox is destroyed on exit
even if an exception is raised:

```python
with miosa.sandboxes.create("miosa-sandbox") as sbx:
    sbx.files.write("/workspace/hello.py", "print('hello')")
    result = sbx.exec.run("python3 /workspace/hello.py")
    print(result.stdout)
# sbx.destroy() called automatically here
```

```typescript
// TypeScript: manual cleanup with try/finally
const sbx = await miosa.sandboxes.create({ templateId: "miosa-sandbox" });
try {
  await sbx.files.write("/workspace/hello.py", "print('hello')");
  const result = await sbx.exec.run("python3 /workspace/hello.py");
  console.log(result.stdout);
} finally {
  await sbx.destroy();
}
```

### Connect to an existing sandbox

```python
# By ID
sbx = miosa.sandboxes.get("sbx_a1b2c3d4")

# By name (if you set name= at create time)
sbx = miosa.sandboxes.get_by_name("my-dev-env")

# connect() is an alias for get()
sbx = miosa.sandboxes.connect("sbx_a1b2c3d4")
```

```typescript
const sbx = await miosa.sandboxes.get("sbx_a1b2c3d4");
// or
const sbx = await miosa.sandboxes.getByName("my-dev-env");
```

```bash
curl https://api.miosa.ai/api/v1/sandboxes/sbx_a1b2c3d4 \
  -H "Authorization: Bearer $MIOSA_API_KEY"

# By name
curl https://api.miosa.ai/api/v1/sandboxes/by-name/my-dev-env \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

## List and filter sandboxes

```python
# All running sandboxes
running = miosa.sandboxes.list(status="running")  # status: "running" | "paused" | "destroyed"

# Filter by name (prefix match)
named = miosa.sandboxes.list(name="my-dev")

# Filter by white-label workspace
ws_sandboxes = miosa.sandboxes.list(external_workspace_id="acme-corp")

# Filter by tags
tagged = miosa.sandboxes.list(tags=["pr-preview", "staging"])
```

```typescript
const running = await miosa.sandboxes.list({ status: "running" });  // status: "running" | "paused" | "destroyed"
const named   = await miosa.sandboxes.list({ name: "my-dev" });
const byCorp  = await miosa.sandboxes.list({ externalWorkspaceId: "acme-corp" });
```

```bash
curl "https://api.miosa.ai/api/v1/sandboxes?status=running" \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl "https://api.miosa.ai/api/v1/sandboxes?name=my-dev" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

See [Lifecycle](/docs/develop/sandboxes/lifecycle/) for the state machine these calls move through, [Environment variables](/docs/develop/sandboxes/environments/) for create-time and exec-level env, and [Sizing and limits](/docs/develop/sandboxes/sizing/) for the resource contracts referenced above.

# Docker in sandboxes

URL: https://miosa.ai/docs/develop/sandboxes/docker
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/docker
Source: src/routes/docs/develop/sandboxes/docker/+page.md
Description: Run containers inside MIOSA sandboxes, publish ports, and reach them through preview URLs. Which templates ship Docker Engine, Compose, and Buildx.

# Docker in sandboxes

Docker is preinstalled in the sandbox image. There is nothing to enable, and no separate template to pick.

```bash
docker run --rm alpine echo hello
docker compose up -d
docker buildx build --load -t myapp .
```

What each template ships today:

| Template | Docker Engine | Compose and Buildx | Runs as `sandbox` user |
|---|---|---|---|
| `miosa-sandbox` (the default) | 29.9 | Yes | As `root` |
| SOMA runtime (`runtime_profile: "soma"`) | 29.9 | Yes | As `root` |

Commands run through `exec` run as `root`, so `docker` works there on every template above that includes it.
Check what a sandbox has with `docker version`, `docker compose version`, and `docker buildx version`.

## What works

| Task | Works |
|---|---|
| `docker run`, `docker exec`, `docker logs`, volumes, bind mounts | Yes |
| `docker compose up` with several services and service-name DNS between them | Yes |
| `docker buildx build` | Yes |
| `docker build` | Yes |
| Pulling from Docker Hub and other public registries | Yes |
| Publishing a port with `-p 8080:80` and opening it through a preview URL | Yes |
| Running as `root` | Yes |
| Running as the `sandbox` user | Yes, when you `exec` as that user |
| Pausing and resuming a sandbox with containers running | Yes, containers keep running |

## Startup behavior

The Docker engine starts the first time you use it, not when the sandbox boots, so sandbox creation stays fast. The first `docker` command in a fresh sandbox takes about 0.6 seconds longer while the engine starts; after that, running an image that is already pulled takes about 0.15 seconds.

If you start containers with `--restart always`, they come back when the engine next starts, which happens on your next `docker` command.

## Open a container port in your browser

Publish the port on the sandbox, then expose it as a [preview](/docs/develop/previews/).

```bash
docker run -d --name web -p 8080:80 nginx:alpine
```

```typescript
const sbx = await miosa.sandboxes.create({ templateId: "miosa-sandbox" });
await sbx.exec.run("docker run -d --name web -p 8080:80 nginx:alpine");
const preview = await sbx.previews.create({ port: 8080 });
console.log(preview.url);
```

```python
with miosa.sandboxes.create("miosa-sandbox") as sbx:
    sbx.exec.run("docker run -d --name web -p 8080:80 nginx:alpine")
    print(sbx.get_url(8080))
```

The preview URL forwards to the published port. Bind to `0.0.0.0` inside the container, which `-p` does for you.

## Disk and memory

Images, layers, and volumes live on the sandbox disk, so they count against its size. The default `small` sandbox has 10 GiB of disk. When the disk is full, a pull or build fails with `no space left on device` and the sandbox keeps running. Free space with `docker system prune -af` and retry.

The engine uses about 40 MiB of memory when idle. Containers share the sandbox's CPU and memory.

## Docker in a sandbox vs Docker Host

| You want | Use |
|---|---|
| Run, build, or test containers while you develop, or let an agent do it | Docker in a sandbox |
| A durable 24/7 deployment URL, custom domains, and rollback for a containerized app | [Docker Host](/docs/docker-host/docker-deploy/) |
| A sandbox whose only job is to be a Docker host with a long-lived disk | A sandbox with `always_on` set |

Docker in a sandbox is for development and automation. It is not a production runtime.

## Templates

- Every sandbox image includes Docker Engine 29.9 with Compose and Buildx, on Firecracker and on SOMA.
- There is no separate Docker template to pick: the sandbox image already includes Docker.

## Limits

- No nested virtualization. KVM and QEMU do not run inside a sandbox.
- Image builds for other CPU architectures need emulation that is not included.
- Docker Swarm ingress is not supported.

# Environment variables

URL: https://miosa.ai/docs/develop/sandboxes/environments
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/environments
Source: src/routes/docs/develop/sandboxes/environments/+page.md
Description: Set sandbox-level env at create time, inherit account-level runtime env by scope and target, and understand precedence, the per-sandbox env API, secret files, and secrets, and how a value reaches exec.

# Environment variables

An environment variable reaches a sandbox from one of several layers: account-level runtime env resolved by scope, values set on the sandbox itself, secrets bound to an opaque placeholder, or `env` passed on a single exec. This page covers what each layer is, how conflicts resolve, and how to read the live set.

## When values are applied

- On create, variables and secrets are applied before the first user command runs.
- On every resume, the sandbox is re-injected with the current set, so a resumed sandbox sees values set after it was created, not only the values it booted with.
- Secret values reach the sandbox only. The API, CLI, and SDKs return the name, metadata, and a short preview, never the plaintext value.
- A snapshot that can be shared or forked across organizations is scrubbed of agent keys and secret values first.

A setup script passed at create runs once, in the background, after the sandbox is ready.
It does not delay `ready`.

## Account-level runtime env

Platform owners define environment variables once and have them inherited by sandboxes, computers, and agent runs. Runtime env is encrypted at rest and never returned as plaintext by the API, CLI, or SDKs. Responses include metadata and a short preview only.

MIOSA resolves runtime env in this order. More specific values override broader values with the same name:

| Precedence | Scope | Applies to |
|---:|---|---|
| 1 | Tenant | Every workspace, project, sandbox, computer, and agent under the tenant |
| 2 | Workspace | Every project, sandbox, computer, and agent in that workspace |
| 3 | Project | Sandboxes, computers, deployments, and agent runs attributed to that project |
| 4 | Resource | Per-sandbox or per-computer env set directly on the resource |
| 5 | Run | Env passed directly to a single exec or agent run |

Each runtime env var also has a **target**. At the same scope, a target-specific value overrides one set to `all`:

| Target | Use it when |
|---|---|
| `all` | The value is safe and useful for every runtime surface |
| `sandbox` | The value should only appear in sandbox exec/build/agent sessions |
| `computer` | The value should only appear in desktop computer commands and agents |
| `agent` | The value should be injected into prompt-driven agent runs on sandboxes or computers |
| `deployment` | Production deployment/runtime boot |

Variable names must be uppercase shell-safe names matching `[A-Z][A-Z0-9_]*`.

Runtime env carries inherited env vars and provider keys by scope and target. An [agent runtime profile](/docs/api-reference/agent-runtime-profiles/) owns runtime choice, tools, policy, and non-secret defaults. A [connector](/docs/security/connect-accounts/) brokers provider identity. Use runtime env for direct provider env vars, connectors when MIOSA should broker access, and profiles to attach the right defaults.

## Sandbox-level env

Env vars passed at create time are injected into the VM at boot and visible to all processes. They are read-only once the sandbox is running; `env.list()` returns the live set.

```python
# Set at create time
sbx = miosa.sandboxes.create(
    env={"DATABASE_URL": "postgres://...", "API_SECRET": "..."},
)

# Read the live env inside a running sandbox
env = sbx.env.list()
print(env)  # {"DATABASE_URL": "postgres://...", ...}
```

```typescript
const sbx = await miosa.sandboxes.create({
  env: { DATABASE_URL: "postgres://...", API_SECRET: "..." },
});

const env = await sbx.env.list();
```

```bash
# Pass at create time (in the POST body)

# Read
curl https://api.miosa.ai/api/v1/sandboxes/$SBX/env \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

## Per-sandbox env API

The `/api/v1/sandboxes/{id}/env` API manages a key-value store attached to a sandbox. Variables are encrypted at rest and injected into the sandbox process environment on start. The API never returns plaintext values, only key names and metadata.

| Method | Path | Description |
|--------|------|-------------|
| `GET` | `/api/v1/sandboxes/{id}/env` | List all env vars (names only, no values) |
| `PUT` | `/api/v1/sandboxes/{id}/env` | Bulk set or update env vars |
| `DELETE` | `/api/v1/sandboxes/{id}/env/{key}` | Delete a single env var |

`PUT` is a bulk upsert: existing keys are updated, new keys are created, and keys not present in the request are left unchanged.

```bash
curl -X PUT https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/env \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "vars": [
      {"key": "DATABASE_URL", "value": "postgres://user:pass@host/db"},
      {"key": "LOG_LEVEL", "value": "info"}
    ]
  }'
```

See [Sandbox Env API](/docs/api-reference/sandbox-env/) for scopes, response shapes, and the error table, and [Runtime Env](/docs/api-reference/runtime-env/) for the inherited-env endpoints.

## Secrets

For credentials you do not want inside the VM at all, store them as secrets. Every sandbox using a secret sees an opaque placeholder env var; the real key never lives inside the VM, and the swap happens on egress.

```python
sandbox.secrets.set(
    name="openai_key",
    value="sk-proj-...",
    expose_as_env="OPENAI_API_KEY",
)
```

Inside the sandbox, `os.environ["OPENAI_API_KEY"]` returns an opaque token such as `miosa-tok-7f2a...`. When your code makes an outbound call, the MIOSA proxy on the VM's host sees the placeholder in the `Authorization` header and swaps it with the real key before forwarding. Rotation is instant: every sandbox picks up the new value on its next outbound request, and the placeholder token does not change.

A secret can be scoped at `tenant`, `workspace`, `user`, `external_user`, or `external_workspace`, and the proxy picks the most specific match for the resource making the request.

Do not store long-lived secrets in a sandbox `env` value: those are stored in the sandbox record and visible to any process inside the VM. Pass them per-exec, use the secret store, or use a connector. See [Secrets](/docs/security/secrets/) for the full workflow.

## How a value reaches exec

When a command runs, MIOSA resolves the effective environment in layers and hands it to the process:

1. Inherited runtime env for the sandbox's scope and target is materialized at boot.
2. Sandbox-level env (create-time `env` or the per-sandbox env API) overrides an inherited value with the same name.
3. Secrets appear as placeholder env vars exposed via `expose_as_env`.
4. `env` passed to a single exec merges on top for that command only.

```python
result = sbx.exec.run(
    "pytest tests/ -x",
    {"cwd": "/workspace", "env": {"PYTHONPATH": "/workspace"}, "timeout_sec": 120},
)
```

[Create and connect](/docs/develop/sandboxes/create/) shows where `env` is passed at create time, and [Connections (OAuth)](/docs/security/connect-accounts/) covers brokered provider credentials.

Source: src/routes/docs/develop/sandboxes/events/+page.md
Description: Subscribe to sandbox lifecycle and activity events over SSE to monitor agent runs and detect unexpected exits.

# Sandbox events

The `events.stream()` endpoint emits lifecycle and activity SSE events for a
sandbox, which is useful for monitoring agent runs.

```python
for event in sbx.events.stream():
    print(event["type"], event.get("data"))
    # types: "sandbox.started", "sandbox.destroyed", "exec.started", "exec.completed", ...
```

```typescript
for await (const event of sbx.events.stream()) {
  console.log(event.type, event.data);
}
```

```bash
curl https://api.miosa.ai/api/v1/sandboxes/$SBX/events \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Accept: text/event-stream"
```

## Logs, metrics, and export

Every sandbox exposes three observability surfaces:

| Surface | Endpoint |
|---|---|
| Logs | `GET /api/v1/sandboxes/{id}/logs` |
| Per-sandbox metrics | `GET /api/v1/sandboxes/{id}/metrics` |
| Lifecycle event stream | `GET /api/v1/sandboxes/{id}/events` - the stream on this page |

A stopped sandbox's disk can be exported as an archive without resuming it.
`GET /api/v1/sandboxes/{id}/exports` reads the saved disk, so it works while the sandbox is `stopped` and does not start compute.

The [Events API reference](/docs/api-reference/events/) documents the full event catalog and payload shapes, and the [production checklist](/docs/develop/sandboxes/production-checklist/) shows how to wire the stream into retry logic.

# Internet access and egress

URL: https://miosa.ai/docs/develop/sandboxes/internet-access
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/internet-access
Source: src/routes/docs/develop/sandboxes/internet-access/+page.md
Description: Whether a sandbox can reach the internet by default, the two layers of egress control, how to lock a sandbox to an allowlist, and how to debug a blocked call.

# Internet access and egress

## Default network behavior

- **Inbound.** A sandbox is not reachable from the internet. Only the ports you expose as a [preview](/docs/develop/previews/) accept traffic, and only through the MIOSA proxy.
- **Outbound.** A new sandbox can reach the internet. It starts in **audit-only** mode: no outbound call is blocked. Egress audit capture is not yet enabled in the current release, so calls are not recorded yet. A Computer's network policy defaults to `unrestricted`.

So by default your code can install packages, call APIs, and clone repos. Nothing is blocked until you choose to enforce an allowlist.

### What a sandbox cannot reach

A sandbox cannot reach the platform's own internal network.
The only exception is the managed-database proxy range, which is what a managed Postgres, MySQL, or Redis connection uses inside the sandbox.
This is a mesh-level deny, checked before the egress allowlist, so adding an internal host to an allowlist does not open it.
It is enforced on both runtimes.

`169.254.169.254` is not an egress destination on MIOSA.
It is Firecracker's metadata service (MMDS), the guest-side channel the host uses to hand a sandbox its identity and configuration, and it is answered inside the machine rather than on the host network.
Leave it denied, as the examples below do.

## Two layers of control

MIOSA gives you two ways to constrain outbound traffic. They compose.

| Layer | Scope | What it decides |
|---|---|---|
| Egress policy + allowlist | Computers and Sandboxes | The hosts a resource may reach, in `audit_only` or `enforce` mode |
| Network policy | Computers | A microVM-level mode: `unrestricted`, `allowlist`, `denylist`, or `isolated` |

A Computer or Sandbox resolves its egress policy as: resource override, then tenant default. The tenant default starts in `audit_only` mode.

## Watch, then enforce

The intended path for a sandbox is to observe real traffic, then lock it down to what it actually uses. This is the same flow documented in full on the [network allowlist reference](/docs/security/network/):

1. **Observe.** Let the sandbox run normally. Every outbound host is recorded.
2. **Review.** Pull the hosts it contacted, ranked by frequency.
3. **Enforce.** Apply those hosts as the allowlist and switch the policy to `enforce`. Unlisted hosts are then blocked.
4. **Operate.** Blocked hosts land in a pending queue with one-click allow or deny. Revert to audit-only at any time without losing the allowlist.

```python
# Suggested allowlist from observed traffic
for h in sandbox.network.suggestions(since="7d"):
    print(h.host, h.request_count)

# Allow, deny, and enforce
sandbox.network.allow("api.openai.com")
sandbox.network.allow("*.anthropic.com", methods=["POST"])
sandbox.network.deny("169.254.169.254")   # Firecracker metadata service (MMDS)
sandbox.network.lockdown()

# Revert, or inspect
sandbox.network.observe()
print(sandbox.network.get_policy().mode)
```

```typescript
const hosts = await sandbox.network.suggestions({ since: '7d' });
await sandbox.network.allow('api.openai.com');
await sandbox.network.allow('*.anthropic.com', { methods: ['POST'] });
await sandbox.network.deny('169.254.169.254');  // Firecracker metadata service (MMDS)
await sandbox.network.lockdown();
await sandbox.network.observe();
const policy = await sandbox.network.getPolicy();
```

### Allowlist rules

| Kind | Example | Matches |
|---|---|---|
| Exact host | `api.openai.com` | Only this hostname |
| Wildcard | `*.openai.com` | Any subdomain of `openai.com` |
| CIDR | `10.0.0.0/8` | Any IP in this range, when the target is an IP literal |

Rules are matched in priority order: exact beats wildcard, wildcard beats CIDR, and an explicit `deny` always beats an `allow`. A rule can be scoped to a method and a path, and marked `warn_only` to let the request through while flagging it in the audit log.

Rules attach at two levels: per-resource (one sandbox or computer) and tenant-wide (every resource unless overridden).

## Restrict a Computer at the microVM level

Computers also accept a network policy that takes effect within seconds, without a restart.

```typescript
await client.networkPolicy.update(computerId, {
  mode: 'allowlist',
  rules: [
    { host: 'registry.npmjs.org', port: 443, protocol: 'tcp' },
    { host: 'pypi.org',          port: 443, protocol: 'tcp' },
  ],
});
```

```bash
curl -X PUT https://api.miosa.ai/api/v1/computers/$COMPUTER_ID/network-policy \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"mode": "allowlist", "rules": [{"host": "github.com", "port": 443, "protocol": "tcp"}]}'
```

| Mode | Description |
|---|---|
| `unrestricted` | Default. All outbound traffic allowed |
| `allowlist` | Only listed hosts and ports permitted |
| `denylist` | All traffic allowed except listed rules |
| `isolated` | All outbound blocked (DNS and MIOSA internal excluded) |

A `PUT` replaces the whole policy; send every rule on every call. `DELETE` resets it to `unrestricted`.

## Credentials on the way out

Egress is also where MIOSA swaps placeholders for real credentials. Your workload sees an opaque `miosa-tok-...` value in its environment; the proxy substitutes the real secret on the outbound request, so the value never lives inside the sandbox. See [Secrets](/docs/security/secrets/) and the [Egress API](/docs/api-reference/egress/).

## Debug a blocked call

```python
# What is being blocked right now
for p in sandbox.network.pending():
    print(p.host, p.request_count, "blocked")

# Or filter the audit log for rejects
for e in sandbox.audit.list(since="1h", action="reject", limit=50):
    print(e.host, e.rejected_by)
```

Common allowlist gaps:

- **`pip install`** needs `pypi.org`, `files.pythonhosted.org`, and `pythonhosted.org`.
- **`npm install`** needs `registry.npmjs.org`; some postinstall scripts also reach `*.github.com`.
- **CDNs and dynamic subdomains** are usually not covered by an exact rule. Use a wildcard like `*.openai.com`.

Every blocked row carries a `rejected_by` field naming the rule that fired. For the full list of fixes, see [Security troubleshooting](/docs/security/troubleshooting/).

Enforcing an allowlist restricts outbound calls only. Preview URLs into your sandbox keep working exactly as before.

Description: The sandbox state machine from creating to destroyed, what each state means, what stop keeps, what resets the idle clock, and how to stop, pause, resume, and restart.

# Sandbox lifecycle

A sandbox moves through a small set of states.
This page is the map: what each state means, what triggers a transition, and how to stop and restart compute without discarding the disk.

## Lifecycle

| State | Meaning |
|---|---|
| `creating` | VM is being claimed, restored, and prepared to accept commands |
| `running` | Command-ready: exec, files, previews, terminal, and port exposure work |
| `stopped` | The machine is released and the disk is saved; files survive, processes do not |
| `paused` | The machine is suspended in place with memory and processes intact; only on a runtime that advertises pause |
| `destroyed` | Terminal: resources freed, ID unusable, saved state removed |
| `error` | Boot or runtime failure; check `sbx.data["metadata"]` for `last_error` |

`paused` exists only on a runtime that advertises pause.
Firecracker advertises it today.
SOMA does not: it has no pause, and it does not keep state across a stop yet, so a SOMA sandbox is never `paused`, and a disposable SOMA sandbox is deleted when its timeout expires.
Snapshots are a separate resource, not a sandbox state.

Activity that resets the idle clock: exec calls, file operations, preview HTTP traffic, terminal stdin.
The timeout is idle-anchored: it counts from the last activity.
Once `timeout_sec` elapses with no activity, a persistent sandbox is stopped.
A non-persistent sandbox (`persistent: false`) is destroyed, and its disk is discarded.

`idle_timeout_sec` stops a persistent sandbox after a period of inactivity.
New accounts (created on or after October 11, 2026): sandboxes without `idle_timeout_sec` stop after 30 minutes idle and wake on the next request.
Set `idle_timeout_sec` to `0` to disable.
Existing accounts keep their current behavior (idle timeout off unless set).

`resume()` is not the only way back out of `stopped` or `paused`: a persistent sandbox **wakes on request**.
A request that arrives while it is stopped or paused (for example, to its preview URL) resumes it and is held for up to 10 seconds, then answers `503` with `Retry-After` if it is not running yet.
Exec, file operations, and deploys on a stopped or paused persistent sandbox resume it first and then run.
A non-persistent sandbox is never auto-resumed: the call returns `409`.

## What stop keeps

Stop saves the disk and releases the machine, and moves the sandbox to `stopped`.
Files, installed packages, Docker data, and enabled services survive a stop.
Running processes never survive a stop, on any runtime.
Resume after a stop behaves like a server that restarts: start your processes again, or make them declared services.

Pause is the explicit verb for keeping processes.
It is available on Firecracker only.
A paused sandbox stays resident for at most 30 minutes, with memory and processes intact.
After 30 minutes it behaves like a stop: the disk is kept and processes are not.
A memory checkpoint is an accelerator, never the truth: if it cannot be restored, resume falls back to the disk.

Disk size is a fixed class (10, 20, or 40 GiB) chosen at create.
It can grow only as a parameter of `resume` or `fork`.
A request to shrink is refused with `409` and the sandbox is left untouched.
Disk growth is not available yet on every runtime.

Persistent means the sandbox survives a stop.
It does not mean the sandbox survives the loss of its host.
The `durability` field on the sandbox record states how many hosts hold the saved state: `local_only`, `replicating`, or `replicated`.
Every Firecracker sandbox exposes `durability`.
It is `local_only` until a stopped sandbox's copy has been verified off-host, and then `replicated`.
Off-host replication is rolling out on a QA canary first, so expect `local_only` for most sandboxes today.

See [Persistence, pause, and forks](/docs/develop/snapshots/) for the full pause/resume/fork flow.

## Readiness and billing

A sandbox is command-ready only in the `running` state. Two signals tell you when it gets there:

- The `ready` boolean on the sandbox record. `true` means the VM session is prepared to accept exec, files, previews, and terminal calls.
- The `state` field. Poll `GET /api/v1/sandboxes/{id}` until `state` leaves `creating` and becomes `running` (or surfaces `error`).

The fused [run endpoint](/docs/develop/sandboxes/create/) owns this wait on the server, so agents that create-and-exec do not need a client poll loop.

Which states cost what:

| State | Billing |
|---|---|
| `creating` | Preparing resources; not yet command-ready |
| `running` | Billed per second at the price of its size (the same on every plan) |
| `stopped` | No compute; cold storage rate only (disk GiB-second) |
| `paused` | No compute; storage rate only (disk GiB-second) |
| `destroyed` | Billing stops immediately |

See [Sizing and limits](/docs/develop/sandboxes/sizing/) for the full billing notes and [Timeouts and auto-stop](/docs/develop/sandboxes/timeouts/) for what happens at the deadline.

## Pause and resume

`POST /stop` and `resume()` release the machine and bring it back on the same disk.
`pause()` and `resume()` suspend the machine in place and keep its processes, on a runtime that advertises pause (Firecracker only, for at most 30 minutes before it behaves like a stop).

```python
sbx.pause()
# Firecracker only: state is "paused" and processes are kept for up to 30 minutes

sbx.resume()
# state returns to "running"
```

```typescript
// Firecracker only: keeps processes for up to 30 minutes
await sbx.pause();
await sbx.resume();
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/stop \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'

curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/resume \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'
```

## Restart

`POST /sandboxes/{id}/restart` (`miosa restart`) is a stop followed by a resume of the same disk, under the same id.
Files, packages, Docker data and enabled services survive; running processes do not, and the guest boots on a fresh kernel.
Reach for it when a running sandbox stops answering commands.
A sandbox that is not running answers `409 SANDBOX_NOT_RUNNING`: resume it instead.

[Timeouts and auto-stop](/docs/develop/sandboxes/timeouts/) covers what happens when `timeout_sec` elapses, [Snapshots and persistence](/docs/develop/snapshots/) covers snapshots and forks, and [Sizing and limits](/docs/develop/sandboxes/sizing/) covers what each state costs.

# Long-running tasks

URL: https://miosa.ai/docs/develop/sandboxes/long-running-tasks
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/long-running-tasks
Source: src/routes/docs/develop/sandboxes/long-running-tasks/+page.md
Description: Work that outlives a single exec: background processes, their logs and status, always-on sandboxes, and what comes back after pause and resume.

# Long-running tasks

A single `exec` call is bounded: the sandbox `exec` endpoint accepts a `timeout` of 1 to 86,400 seconds (default 3,600), independent of the sandbox's own timeout. Work that runs longer - a dev server, a build, a watcher, a worker - should be started as a background process and inspected separately.

## Start a background process

```python
proc = client.sandboxes.processes.start(
    "sbx_abc123",
    cmd="npm run dev -- --port 3000",
    cwd="/workspace",
    name="dev-server",
)
print(proc.pid)   # proc_...
```

```typescript
const proc = await client.sandboxes.processes.start('sbx_abc123', {
  cmd: 'npm run dev -- --port 3000',
  cwd: '/workspace',
  name: 'dev-server',
});
```

```bash
miosa process start --name build --cwd /workspace/app -- npm run build
miosa ps            # list processes (alias for: miosa process list)
```

The body accepts `cmd` (required), `cwd`, `env`, and `name`. The sandbox must be `running` to start a process.

## Check status and logs

| Status | Meaning |
|---|---|
| `running` | Process is alive |
| `exited` | Process exited normally |
| `killed` | Process was stopped via `DELETE` |
| `error` | Process failed to start |

Fetch the last N lines of stdout+stderr, or stream them live:

```bash
# Last 50 lines
curl "https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/processes/proc_01hwxyz/logs?tail=50" \
  -H "Authorization: Bearer $MIOSA_API_KEY"

# Live stream (SSE)
curl "https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/processes/proc_01hwxyz/stream" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Stop a process with `DELETE`, which sends `SIGTERM` and then `SIGKILL` after a grace period.

## Daemons for long-lived services

A sandbox daemon is a named long-lived process: start it once, then list it, read
its output and restart or stop it by name instead of hunting for a pid.

```bash
miosa daemon create my-box --name web --command "npm run dev" --cwd /workspace/app
miosa daemon list my-box
miosa daemon logs my-box web
miosa daemon restart my-box web
miosa daemon stop my-box web
```

The same calls are `POST /api/v1/sandboxes/:id/daemons`, `GET .../daemons` and
`GET .../daemons/:name`; the [Processes API](/docs/api-reference/sandbox-processes/)
documents the process model they sit on.

On Computers, long-lived daemons belong to systemd and restart on failure rather
than to a process table; see the [Services API](/docs/api-reference/services/).

## Keep a sandbox alive

A background process only runs while the sandbox does. Two settings control that:

- **`always_on: true`** disables timeout and idle-timeout enforcement until an explicit lifecycle action, subject to tenant policy.
- **`idle_timeout_sec`** stops an abandoned persistent session after a period of inactivity; `0` disables idle auto-stop. Left unset, it defaults to `0`, or `1800` (30 minutes) for accounts created on or after October 11, 2026. A stopped sandbox wakes on the next request.

The timeout is idle-anchored.
For persistent sandboxes, expiry stops the sandbox rather than destroying it, and a stop never keeps running processes.
Explicitly non-persistent sandboxes are destroyed. See [Timeouts and auto-stop](/docs/develop/sandboxes/timeouts/).

A background process lives for the lifetime of its running session. It never survives a stop, and it is not preserved across a snapshot, restore, or fork. Only a pause (Firecracker only) keeps processes, and only for up to 30 minutes, after which the sandbox behaves like a stop. Re-start the process after the sandbox is running again, or make it a declared service so it is easy to relaunch.

# Metadata and labels

URL: https://miosa.ai/docs/develop/sandboxes/metadata
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/metadata
Source: src/routes/docs/develop/sandboxes/metadata/+page.md
Description: Attach arbitrary metadata to a sandbox at create time, read it back, and use external IDs for anything you need to query or bill on.

# Metadata and labels

Every sandbox record carries a `metadata` object you supply at create time. It is stored on the record and returned on reads. It is free-form: MIOSA stores it and never interprets it.

## Set metadata at create

```python
sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    metadata={"team": "growth", "ticket": "ENG-482", "run": "nightly"},
)
print(sandbox.metadata)   # {"team": "growth", "ticket": "ENG-482", "run": "nightly"}
```

```typescript
const sandbox = await client.sandboxes.create({
  templateId: 'miosa-sandbox',
  metadata: { team: 'growth', ticket: 'ENG-482', run: 'nightly' },
});
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"template_id": "miosa-sandbox", "metadata": {"team": "growth", "ticket": "ENG-482"}}'
```

The CLI sets the same field with repeated `--meta` flags:

```bash
miosa create my-box --meta team=growth --meta ticket=ENG-482
```

## Metadata or external IDs?

These are two different things, and the choice matters:

| Field | Queryable? | Use it for |
|---|---|---|
| `metadata` | Returned on read, not a list filter | Notes, tags, and pointers you read back with the record |
| `external_user_id`, `external_workspace_id`, `external_project_id` | Yes: list and usage filters | Anything you need to list, group, or bill on |

`GET /api/v1/sandboxes` filters by `workspace_id`, `project_id`, `external_workspace_id`, `external_user_id`, `external_project_id`, and `state`. It does not filter by `metadata`. If you need to enumerate every sandbox for one of your customers, use an external ID, not a metadata key.

The three `external_*` fields propagate to every usage record, audit event, and derived resource (previews, deployments) automatically, which is what per-tenant chargeback needs. Metadata does not. See [Ownership and attribution](/docs/platform/attribution/).

## Per-tenant attribution

For per-tenant products, stamp the external IDs at create and read them back on every record:

```python
sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    external_workspace_id="acme-corp",
    external_user_id="user-42",
    external_project_id="q3-dashboard",
    metadata={"requested_by": "jane@acme.example"},
)
```

Both fields are covered end to end in [Multi-tenant SaaS](/docs/cookbook/multi-tenant-saas/).

# Production checklist

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/production-checklist
Source: src/routes/docs/develop/sandboxes/production-checklist/+page.md
Description: The defaults to set on sandboxes before relying on them in production: timeouts, persistence, idempotency, templates, secrets, and event subscription.

# Production checklist

Before relying on sandboxes in production:

- Set an explicit `timeout_sec`. Interactive app-building workflows should usually use `1h`; short one-shot commands can use less.
- Keep the default `persistent=True` for agent workspaces so timeout preserves `/workspace` and dependency installs.
- Set `idle_timeout_sec` for user-facing dev environments so abandoned sessions stop compute and preserve state.
- Pass `idempotency_key` on `sandboxes.create` calls in agent retry loops. The platform deduplicates creates with the same key within a 24-hour window, and the key also makes an uncertain placement outcome retryable: the API answers a retryable `503 SANDBOX_PLACEMENT_RECONCILING` instead of a terminal `409`.
- Use a published template instead of reinstalling the same dependencies for every sandbox.
- Fork before destructive operations when you need an independent branch of the current running state.
- Subscribe to `sbx.events.stream()` to detect unexpected exits and trigger retries.
- Never store long-lived secrets in `env`; pass them per-exec or use the Secrets API.
- Filter by `external_workspace_id` in your list calls to avoid scanning your entire tenant's sandbox set.

[Timeouts and auto-stop](/docs/develop/sandboxes/timeouts/) explains `timeout_sec` and usage measurement, [Sizing and limits](/docs/develop/sandboxes/sizing/) explains `persistent` and `always_on`, and [Sandbox events](/docs/develop/sandboxes/events/) covers the event stream.

# Sizing and limits

URL: https://miosa.ai/docs/develop/sandboxes/sizing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/sandboxes/sizing
Source: src/routes/docs/develop/sandboxes/sizing/+page.md
Description: Named sandbox resource contracts, raw resource overrides, how sandbox usage is billed, and the opt-in runner fast path.

# Sizing and limits

Every sandbox runs on a named resource contract.
Pick a `size` by name; the raw CPU, memory, and disk fields are compatibility inputs that must exactly match a published contract.

## Sizing reference

| Size name | vCPU | RAM | Disk | Notes |
|---|---|---|---|---|
| `xs` | 1 | 2 GB | 10 GB | Lightweight scripts |
| `small` | 2 | 4 GB | 10 GB | **Default for agent and build workloads** |
| `medium` | 4 | 8 GB | 20 GB | Larger builds and parallel tests |
| `large` | 8 | 16 GB | 40 GB | Heavy test suites |
| `xl` | 16 | 32 GB | 80 GB | Intensive parallelism |

Use the default `small` contract for Claude Code, Codex, package installation, ordinary application builds, and agent execution.
Choose `medium` only when measured CPU, memory, or disk requirements exceed `small`.
Raw resource fields are compatibility inputs and must exactly identify a published named contract.

**Raw resource overrides** (still accepted):

| Field | Default | Validation range |
|---|---|---|
| `cpu_count` | 2 | 1-16 |
| `memory_mb` | 4096 | 2048-32768 |
| `disk_size_mb` | 10240 | Must match the selected named contract |
| `timeout_sec` | 3600 | 1-86400 |
| `idle_timeout_sec` | 0 (1800 on accounts created on or after October 11, 2026) | 0-86400 |
| `always_on` | `false` | Not required for most agent work |
| `persistent` | `true` | Preserve the disk across stops and resumes (survives stop, not host loss) |

Set `always_on=True` to disable `timeout_sec` enforcement entirely. Useful for long-lived development environments or hosted IDEs. Set `idle_timeout_sec` to stop an abandoned persistent session after a period of inactivity. Set `persistent=False` only for one-off jobs where the filesystem should be discarded on stop or timeout.

**Idle auto-stop default.** New accounts (created on or after October 11, 2026): sandboxes without `idle_timeout_sec` stop after 30 minutes idle and wake on the next request. Set `idle_timeout_sec` to `0` to disable. Existing accounts keep their current behavior (idle timeout off unless set).

## Configuration vs per-sandbox parameters

Platform configuration defines what can be selected: template aliases, immutable image generations, named resource contracts, readiness, placement policy, and tenant limits.
Customers inspect that configuration with `GET /api/v1/templates`; applications do not send internal placement, host, or provider fields.

Per-sandbox parameters select behavior for one sandbox.
They include `template_id`, `size`, `timeout_sec`, `always_on`, `persistent`, and `idle_timeout_sec`.
Prefer a named `size` over raw CPU, memory, and disk fields.
If compatibility fields are used, `cpu_count`, `memory_mb`, and `disk_size_mb` must be supplied together and exactly match one published contract.

The default is `small`: 2 vCPU, 4096 MiB RAM, and 10240 MiB disk.
`xs` is available for lighter work when the template catalog reports it for the selected template and current readiness permits admission.
Every sandbox response includes a versioned `resource_contract`, such as `sandbox/small@v1`, so clients can record the resolved resources instead of assuming a size name will never evolve.

```json
{
  "template_id": "miosa-sandbox",
  "size": "small",
  "timeout_sec": 3600,
  "persistent": true,
  "idle_timeout_sec": 0
}
```

## Resizing a running sandbox

A running Firecracker (`standard`) sandbox can be resized in place: vCPU, memory, or both, without destroying or recreating it.
The filesystem under `/workspace` is preserved.
Sizes are named contracts, so a resize moves a sandbox between published contracts rather than to an arbitrary value.

Read what the sandbox has and what it can change live, without changing anything.
Every sandbox reports its own capabilities, so a client acts on the answer instead of assuming:

```
GET /api/v1/sandboxes/:id/resources

{ "id": "...",
  "resources": { "cpu": 2, "memory_mb": 4096 },
  "capabilities": { "live_cpu": true, "live_cpu_max": 2,
                    "live_memory": false, "live_memory_max_mb": null,
                    "cpu_mechanism": "cgroup_quota", "runtime_engine": "firecracker" } }
```

```typescript
const r = await sandbox.resources();
```

```python
r = sandbox.resources()
```

Change it, sending only the fields you want to change:

```
PATCH /api/v1/sandboxes/:id/resources
{ "cpu_count": 4, "memory_mb": 8192 }
```

```typescript
await sandbox.resize({ cpuCount: 4, memoryMb: 8192 });
```

```python
sandbox.resize(cpu_count=4, memory_mb=8192)
```

```bash
miosa sandbox resources my-box
miosa sandbox resize my-box --cpu 4 --memory 8192
```

What is live today:

- **vCPU** is live on a running Firecracker sandbox, up to the count the sandbox booted with, and only on a host with the vCPU controller enabled.
  The guest keeps the cores it booted with; the host caps the time they may use with a cgroup quota, so a lower vCPU count throttles rather than removes cores.
- **Memory** is live on a running Firecracker sandbox booted with a hotpluggable region (virtio-mem): growing plugs memory into the guest, shrinking unplugs it, and memory never goes below the booted size.
  `live_memory_max_mb` is the ceiling for that sandbox, 16384 MiB by default.
  Live memory is rolling out across the warm pool: a sandbox from an older warm slot reports `live_memory: false` until that slot is rebuilt, and so does a sandbox restored from a snapshot.
- **SOMA** sandboxes apply vCPU and memory live on their own host, up and down (vCPU by cgroup quota, memory by virtio-mem), where the platform has enabled it for that host.

Read `capabilities` before a resize, and again from the resize response.
`live_cpu`, `live_memory`, and their maxima are per sandbox, per host, and per image generation; the `*_reason` field says why a change is not live when it is not.

A change that cannot be applied live is reported `requires_restart`: the request answers `409 RESIZE_REQUIRES_RESTART`, nothing is applied, and nothing is stored as pending.
A request above your plan cap answers `422 PLAN_CAP_EXCEEDED`; a SOMA sandbox or a host without the controller answers `409 RESIZE_UNSUPPORTED`.

Send `"restart": true` to boot the same disk at the new size instead.
This is a recreate, not an in-place change: the filesystem survives, the new sandbox has a new id, the processes of the old one are gone, and the source is left paused and billed as a paused sandbox until you destroy it.
The response is `202` with `restarted: true`, `new_sandbox`, and `source_sandbox`.
SOMA sandboxes have no host disk to boot from, so they are not recreated this way.

## Billing notes

Billing accrues from `state = "running"` until `state = "stopped"`, `state = "paused"`, or `state = "destroyed"`.

- **Running**: billed per second at the price of its size, the same on every plan and whether the machine is idle or busy (for example `small` is $0.0893 an hour)
- **Stopped**: billed at the cold storage rate (disk GiB-second)
- **Paused**: billed at storage rate only (disk GiB-second)
- **Destroyed**: billing stops immediately

Template readiness and available sizes are reported by the catalog and can vary by environment.

## Runner endpoints (opt-in preview)

The SOMA one-hop runner is an opt-in fast path for `create`, `exec`, and `destroy`: your SDK talks straight to the runner instead of going through the control plane first. Everything documented here keeps working unchanged whether or not you opt in.

- `https://run-us.miosa.ai` works for every call. Opting in sends requests there instead of `https://api.miosa.ai`; EU is on the roadmap, but keys do not carry a region yet. This endpoint is unrelated to a sandbox's placement [region](/docs/api-reference/regions/) (`us-west`, `us-east`, `us-mia`).
- A request for a sandbox that lives on a different host inside the runner fleet is forwarded internally; you almost always get an answer from `run-us.miosa.ai` directly (`421` is a rare fallback if that internal forward fails, naming the correct URL as `runner_url`). For lower latency, every `create` response also names that sandbox's own runner URL as a `Soma-Runner-Url` response header (`https://<tag>.run-us.miosa.ai`); official SDKs read it and call that URL directly from then on. This is an automatic optimization, not something you need to do yourself.
- `create` on the runner only serves the default template, `xs` size, non-persistent sandboxes. A request outside that (a custom template, a snapshot, a custom `cwd`, `persistent: true`, or a larger size) answers `400 RUNNER_UNSUPPORTED_REQUEST`; official SDKs send that create to `https://api.miosa.ai` automatically instead.
- The runner only creates non-persistent sandboxes, so the idle auto-stop default does not apply here: idle timeout stays off unless you set `idle_timeout_sec` (0-86400 s). `timeout_sec` (default 3600, max 86400) caps lifetime, and `always_on=True` disables the timeout entirely for long-lived sandboxes and hosted IDEs.
- `exec` defaults to a 30 second timeout, same as the control plane. `POST /api/v1/sandboxes/{id}/exec/stream` streams stdout/stderr as server-sent events, ending with an exit event.
- `destroy` responses include `cpu_ms` and `lifetime_ms` for this sandbox's usage.
- `429 runtime_busy` (with `Retry-After: 0`) means this runner is at its admission limit; retry the request. `429 rate_limited` is a per-key or per-tenant rate limit, same semantics as the control plane. `503 feed_stale` means the runner's key and policy data is too old to accept new creates; its existing sandboxes keep working.
- Runners serve HTTP/3 (QUIC) first and fall back to HTTP/2 automatically if QUIC is blocked on your network. Official SDKs handle the fallback for you.

A raw HTTP client can use either the regional URL or the per-sandbox URL named in the `Soma-Runner-Url` header:

```bash
curl -i -X POST https://run-us.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"template_id": "miosa-sandbox"}'
# Soma-Runner-Url: https://3.run-us.miosa.ai

curl https://3.run-us.miosa.ai/api/v1/sandboxes/3a1b2c3d-1111-2222-3333-444444444444 \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Every runner response adds a `Server-Timing` header breaking `auth`, `pool`, and `exec` time down in milliseconds.

### Errors specific to the runner path

| Status | Code | Cause |
|--------|------|-------|
| 401 | `unauthorized` | The key is unknown or revoked in this runner's in-memory table. |
| 403 | `forbidden` | The tenant is not enabled for this path, is suspended, or the project is not allowed. |
| 400 | `RUNNER_UNSUPPORTED_REQUEST` | This create shape is not served by the runner (see above). Official SDKs retry it against `https://api.miosa.ai`. |
| 429 | `rate_limited` | Per-key or per-tenant rate limit, same semantics as the control plane. |
| 429 | `runtime_busy` | This runner is at its admission limit (`Retry-After: 0`). Retry the request; `run-us.miosa.ai` resolves to every runner in the region, so a retry can land on a different one. |
| 503 | `feed_stale` | This runner's key and policy data is older than its freshness limit (`Retry-After: 0`). Creates are refused; its existing sandboxes keep working. |
| 421 | `misdirected` | Rare: the internal forward to the sandbox's own host failed. The body names the correct URL again as `runner_url`. Follow it once; do not retry the original URL. |

The full endpoint contract (request and response bodies) is unchanged by runner mode; only the host you send them to changes. See the [Sandboxes API](/docs/api-reference/sandboxes/) for the control-plane reference.

Runner mode is an opt-in preview rolling out gradually by tenant and host. Until you opt in, every request keeps going through the control plane exactly as documented above.

Description: The sandbox active-session timeout, how to extend it, and how runtime, CPU, and network usage are measured and reported.

# Timeouts and auto-stop

`timeout_sec` is the idle-anchored timeout: it counts from the last activity.
It defaults to 3600 seconds and accepts values from 1 through 86400.
`POST /api/v1/sandboxes/{id}/extend` replaces that timeout; it does not add seconds to the previous value.
An omitted extend body preserves the current timeout.
Set `always_on: true` only when policy permits a sandbox to run until an explicit lifecycle action.

## Auto-stop semantics

`timeout_sec` counts from the last activity, not from when the session started.
Exec calls, file operations, preview HTTP traffic, and terminal stdin all reset it.
When it expires:

- A **persistent** sandbox (`persistent: true`, the default) is stopped and moves to `stopped`. The disk is preserved, so resume brings it back with `/workspace` and installed dependencies intact. Running processes do not survive a stop. Billing drops from the compute rate to the cold storage rate.
- A **non-persistent** sandbox (`persistent: false`) is destroyed, and the disk is discarded.

SOMA sandboxes do not support persistence yet, so a SOMA sandbox is disposable and is deleted when its timeout expires.

## Idle auto-stop and wake on request

`idle_timeout_sec` stops a persistent sandbox after it has been idle.

New accounts (created on or after October 11, 2026): sandboxes without `idle_timeout_sec` stop after 30 minutes idle and wake on the next request. Set `idle_timeout_sec` to `0` to disable. Existing accounts keep their current behavior (idle timeout off unless set).

A stopped persistent sandbox **wakes on request**: a request to its preview URL resumes it and is held for up to 10 seconds. If the sandbox is not running by then, the request returns `503` with `Retry-After` while the resume finishes in the background, so a retry finds the sandbox running. Exec, file operations, and deploys on a stopped or paused persistent sandbox resume it first and then run. A non-persistent sandbox is never auto-resumed: the call returns `409`. Authorization is checked first, so a private preview never wakes for anonymous traffic, and a request for a port that is not exposed does not wake the sandbox.

`POST /api/v1/sandboxes/{id}/extend` replaces the timeout. It does not add seconds to the previous value, so compute the new absolute TTL when you extend. Omitting the body preserves the current timeout. See [Sandbox lifecycle](/docs/develop/sandboxes/lifecycle/) for the stop transition this triggers.

## Sandbox usage

`GET /api/v1/sandboxes/{id}/usage` returns `runtime_sec`, `provisioned_vcpu_ms`, `active_cpu_ms`, network ingress and egress bytes, estimated cost, and timeout visibility.
`runtime_sec` and `provisioned_vcpu_ms` are allocation measurements.
Use `measurement_status` before interpreting active CPU or network values:

| Status | Meaning | Client behavior |
|---|---|---|
| `measured` | The value was measured for this sandbox. | Display and aggregate it normally. |
| `unavailable` | No trustworthy measurement is available. The related value is `null`. | Show "Unavailable"; never coerce it to zero. |
| `stale` | The value is the latest retained sample but is not current. | Label it stale and avoid presenting it as real-time usage. |

Provisioned resources are always reported with `measurement_status.provisioned_resources: "measured"`.
`timeout_remaining_ms` can be `null` before start or when timeout enforcement is disabled.

[Sandbox lifecycle](/docs/develop/sandboxes/lifecycle/) covers what a persistent sandbox becomes when the timeout elapses, and [Sizing and limits](/docs/develop/sandboxes/sizing/) covers the `always_on`, `persistent`, and `idle_timeout_sec` fields.

# Snapshots, restore, pause, and forks

URL: https://miosa.ai/docs/develop/snapshots
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/snapshots
Source: src/routes/docs/develop/snapshots/+page.md
Description: Create durable sandbox checkpoints, restore or fork new sandboxes, and preserve work through pause and resume.

# Snapshots, restore, pause, and forks

MIOSA sandboxes are persistent by default.
Persistent means the sandbox survives a stop: the sandbox record and disk outlive an individual running session until the sandbox is destroyed.
It does not mean the sandbox survives the loss of its host; the `durability` field states that, and it reports `local_only` until off-host replication is verified for a runtime.
SOMA sandboxes do not support persistence, pause, or snapshots yet.

## Sandbox state lifecycle

The sandbox record has six public states.
`paused` exists only on a runtime that advertises pause, which is Firecracker today.
Snapshots and forks are separate resources and operations, not additional sandbox states.

Diagram:
flowchart TB
    create([Create]) --> creating[creating]
    creating -->|runtime ready| running[running]
    running -->|stop or timeout| stopped[stopped]
    stopped -->|resume| running

    running -. runtime failure .-> error
    running -->|destroy| destroyed[destroyed]
    stopped -->|destroy| destroyed
    paused -->|destroy| destroyed
    error -->|delete failed record| destroyed

| State | Meaning |
|---|---|
| `creating` | The sandbox is being prepared and is not ready for work. |
| `running` | Compute is active and the sandbox is ready for supported operations. |
| `stopped` | The machine is released and the disk is saved. Files survive; processes do not. |
| `paused` | The machine is suspended in place with memory and processes intact, for up to 30 minutes, then it behaves like a stop. Firecracker only. |
| `error` | Creation or runtime recovery failed. Inspect the failure reason before destroying or replacing the sandbox. |
| `destroyed` | The sandbox and saved workspace have been permanently released. |

Stop, pause, and resume keep the sandbox ID and disk.
Restore and fork create a different sandbox with a new ID.

## Snapshots, restore, and fork

A snapshot is a durable checkpoint resource with its own lifecycle.
Creating one does not change the sandbox into a `snapshot` state.
Restore and fork both produce a new sandbox while leaving the source sandbox unchanged.
Restoring a snapshot into the same sandbox (revert) is not available yet.
Snapshots are taken on lifecycle events (stop, pause, fork) and on request.
Periodic automatic snapshots are not promised.
Snapshots are not available on SOMA yet.

### Snapshot retention

- The latest stop snapshot is kept for the life of the sandbox.
- Named snapshots are kept until you delete them, subject to your plan quota.
- Destroying a sandbox deletes its snapshots after a 24 hour grace period.
- Memory checkpoints expire 72 hours after the pause. Resume then falls back to the disk.

### Snapshots as templates

A named snapshot can be the source of new sandboxes with `source: "snapshot:<id>"`.
Templates are versioned and immutable per version.
A snapshot is scrubbed of agent credentials and secrets before it can be shared or forked across tenants.
Each fork gets its own machine id, SSH host keys, and session keys.

    restored --> creatingA[creating]

    creatingA --> runningA[running]
    creatingB --> runningB[running]

| Operation | Source requirement | Result | Source changes? |
|---|---|---|---|
| Create snapshot | Running sandbox | A snapshot progresses through `creating`, `uploading`, then `ready`, or ends in `failed` or `quarantined`. | No. |
| Restore snapshot | Ready snapshot | A new sandbox is provisioned from the checkpoint. | No. |
| Fork sandbox | Running sandbox | MIOSA captures a copy-on-write checkpoint and provisions a new sandbox. | The source is briefly coordinated for capture, then continues running. |
| Delete snapshot | Existing snapshot | The snapshot becomes `deleted`; sandboxes previously restored from it are unaffected. | No. |

### Snapshot statuses

| Status | Meaning |
|---|---|
| `creating` | MIOSA is capturing the checkpoint files. |
| `uploading` | MIOSA is compressing, uploading, and finalizing the checkpoint. |
| `ready` | The snapshot passed validation and can be restored. |
| `restoring` | A restore job is using the checkpoint to create a new sandbox. |
| `failed` | Snapshot creation or restore encountered an unrecoverable error. |
| `quarantined` | Artifact integrity validation failed, so MIOSA will not restore it. |
| `deleted` | The snapshot was explicitly deleted or removed by retention policy. |

## Stop, pause, and resume

Stop a running persistent sandbox when work should end without discarding the disk.
Stop keeps files, installed packages, and enabled services.
It never keeps running processes.
Pause is the separate, explicit verb for keeping processes, and it exists on Firecracker only.
A paused sandbox stays resident for at most 30 minutes, then it behaves like a stop.
A memory checkpoint is an accelerator, never the truth: if it cannot be restored, resume falls back to the disk.
SOMA has no pause today.
Exec, file operations, and deploys on a stopped or paused persistent sandbox resume it first and then run, and a preview request wakes it and is held for up to 10 seconds before a `503` with `Retry-After`. A non-persistent sandbox is never auto-resumed and the call returns `409`. An explicit resume is clearer when the application needs to wait for `running` state.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/pause \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/resume \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Idempotency-Key: resume-session-001"
```

Pause returns `409` when the sandbox is not running.
Resume returns `409` when the sandbox is not stopped or paused.
A disk can grow only as a parameter of resume or fork, and a request to shrink it is refused with `409`.

## Timeout and persistence

`timeout_sec` defaults to 3600 and accepts values from 1 through 86400.
The timeout is idle-anchored: it counts from the last activity.
When it expires, a persistent sandbox is stopped and its disk is preserved for a later session, and a non-persistent sandbox is destroyed.
`idle_timeout_sec: 0` disables idle auto-stop. Left unset, it defaults to `0`, or `1800` (30 minutes) for accounts created on or after October 11, 2026; a stopped sandbox wakes on the next request.
`always_on: true` disables timeout and idle-timeout enforcement until an explicit lifecycle action, subject to tenant policy.

Replace the active-session timeout with the extend endpoint:

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/extend \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"timeout_sec": 7200}'
```

The value replaces the timeout rather than adding time to it.
Omitting the request body preserves the current timeout.

## Fork from a snapshot

Fork creates a new sandbox from a copy-on-write snapshot of a running sandbox.
The source is unchanged, and the response is the newly created sandbox.
Use an idempotency key when retrying a fork request.

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/fork \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: fork-auth-experiment-001" \
  -d '{"timeout_sec": 3600}'
```

The optional body accepts `timeout_sec` and `template_id` for the new sandbox.

Public V1 exposes standalone snapshot create, list, inspect, delete, and restore operations in addition to snapshot-backed fork, pause, and resume.
Snapshot IDs are durable resource IDs, but a snapshot only captures the sandbox disk and, where the runtime advertises it, memory.
External databases, object storage, connectors, and third-party services are not rolled back with it.

```bash
miosa snapshot save <sandbox-id> "before migration" --json
miosa snapshot list <sandbox-id> --json
miosa snapshot info <snapshot-id> --json
miosa snapshot fork <snapshot-id> --json
miosa snapshot delete <snapshot-id> --json
```

## What survives what

Persistence in MIOSA spans four separate things. They are not interchangeable:

| Mechanism | What it preserves | Scope |
|---|---|---|
| Stop and resume | The sandbox record and its disk, on the same sandbox id; no processes | One sandbox |
| Pause and resume (Firecracker only) | The disk and the running processes for up to 30 minutes, on the same sandbox id | One sandbox |
| Snapshot and restore | The sandbox disk (and memory, where advertised) captured at a point in time, restored into a new sandbox | One sandbox, copyable |
| Volumes | A block device attached to a compatible computer on the same host | Host-bound, survives computer restarts |
| Templates | The boot image a sandbox starts from (built-in or custom) | Shared across sandboxes |

What a snapshot does **not** save: external databases, object storage buckets, connectors, and any third-party service the sandbox talked to. Restoring a checkpoint does not roll those back. Put durable state in [Postgres](/docs/data/postgres/), [Storage](/docs/data/storage/), or a [Volume](/docs/data/volumes/) if it must outlive a restore.

## Choosing between pause, snapshot, and fork

| You want to | Use | Result |
|---|---|---|
| Stop paying for compute and come back later to the same sandbox | Stop, then resume | Same sandbox id, same disk, same files; processes are not kept |
| Keep processes alive across a short break (Firecracker only) | Pause, then resume within 30 minutes | Same sandbox id, same files, same processes |
| Keep a known-good point to roll back to | Snapshot, then restore | A new sandbox from the checkpoint; the source is untouched |
| Branch one running sandbox into independent experiments | Fork | A new sandbox with its own id, lifecycle, and timeout |
| Reproduce a starting point for many sandboxes | Template | A boot image every new sandbox shares |

A source sandbox can be forked while it keeps running; forks capture a copy-on-write checkpoint. Use a distinct idempotency key per branch, and retry a branch with the same key.

## Failure recovery

- If a branch is corrupted, leave the source unchanged, destroy the failed branch, and fork again with a new idempotency key.
- If the source itself must change, fork it first and make the change in the new sandbox.
- Stop the source when it should stay available for later work without active execution.

## Managed and BYOC behavior

The lifecycle contract is the same on MIOSA-managed capacity and supported BYOC capacity.
Applications send sandbox parameters such as template, size, and timeout.
Placement configuration remains outside the sandbox request, and sandbox responses do not expose internal host or provider fields.


    Resource contracts, create parameters, usage, files, exec, and previews.

# Templates

URL: https://miosa.ai/docs/develop/templates
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/develop/templates
Source: src/routes/docs/develop/templates/+page.md
Description: The one sandbox image, the templates that stage content inside it, the desktop, and how to start a Next.js, FastAPI, or static project.

# Templates

A **template** is content staged inside the sandbox at create time: files, a scaffold, extra packages, and the command that starts your app.
A template is never a separate image.

Every sandbox boots the same main image, which already has Node, Python, Docker Engine 29.9 with `docker compose` and `docker buildx`, a live browser with CDP on a virtual display, and the code interpreter inside.

## New sandbox

Create a sandbox with no template for code, commands, and artifacts.
Use `template_id` when you want a scaffold staged inside the same image.

```python

client = miosa.Miosa(api_key="msk_u_...")

sandbox = client.sandboxes.create()
```

```typescript

const miosa = new Miosa({ apiKey: 'msk_u_...' });

const sandbox = await miosa.sandboxes.create();
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{}'
```

## Start from a template

Pass `template_id` to stage a scaffold inside the sandbox image and start it.
The template provisions the files, the packages, and the command that runs your app; it is not a separate image.

| `template_id` | What it stages |
|---|---|
| `nextjs` | A Next.js app, started on port 3000. |
| `nextjs-postgres` | A Next.js app with Postgres client tooling on port 3000; bind `DATABASE_URL`. |
| `static-html` | Static HTML, CSS, and JavaScript served from `/workspace` on port 8000. |
| `fastapi-auth` | A FastAPI starter with signup, login, me, and dashboard routes, on port 8000. Its health check does not work yet, so do not gate your own readiness on it. |
| your own | Any custom template your workspace has built. See [Custom templates](#custom-templates). |

```python
sandbox = client.sandboxes.create(
    template_id="nextjs",
    auto_start=True,
)
```

```typescript
const sandbox = await miosa.sandboxes.create({
  templateId: 'nextjs',
  autoStart: true,
});
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{ "template_id": "nextjs", "auto_start": true }'
```

With `auto_start`, MIOSA starts the template once the sandbox reaches `running` and the response carries the preview URL.
Leave it `false` when you want to write your own files into `/workspace` first, then call [Start a template app](/docs/api-reference/sandboxes/create#start-a-template-app).

### Next.js

**Port 3000.** Next.js SSR deployments need `output: "standalone"` in `next.config.js` so the builder can package the server.
Static exports (`output: "export"`) work without it.

Or do it by hand against a sandbox you created without `auto_start`:

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/template/start \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "install_command": "npm install",
    "start_command": "npm run dev -- --hostname 0.0.0.0 --port 3000",
    "port": 3000
  }'
```

### FastAPI

**Port 8000.** Or do it by hand:

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/template/start \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "install_command": "pip install -r requirements.txt",
    "start_command": "uvicorn main:app --host 0.0.0.0 --port 8000",
    "port": 8000
  }'
```

### Static HTML

**Port 8000.** Plain HTML, CSS, and JavaScript, with no build step.
Or do it by hand:

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/template/start \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "start_command": "python -m http.server 8000 --bind 0.0.0.0",
    "port": 8000
  }'
```

The builder detects a static site (no `package.json`, `Cargo.toml`, or `go.mod`) and packages `/workspace` as a Static Release, so assets are served from the edge with no Runtime Instances.

Older image ids still work as `template_id` and boot the main image.
The [Sandbox Templates API](/docs/api-reference/sandbox-templates/) lists them.

---

## New desktop

A durable Linux desktop (Xfce and Firefox) with screenshot, click, type, and streaming, plus human takeover.
It is a **Computer** with `template_type: "miosa-desktop"`, not a sandbox template.

```python
computer = client.computers.create(
    name="my-desktop",
    template_type="miosa-desktop",
    size="small",
)
```

```typescript
const computer = await miosa.computers.create({
  name: 'my-desktop',
  templateType: 'miosa-desktop',
  size: 'small',
});
```

```bash
curl -X POST https://api.miosa.ai/api/v1/computers \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{ "name": "my-desktop", "template_type": "miosa-desktop", "size": "small" }'
```

See [Computers](/docs/computers/overview/) for the desktop surface, and [Embed a live desktop](/docs/computers/embedding/) to put it in your product.

---

## Custom templates

When the built-in catalog does not fit  -  proprietary toolchains, specific CUDA/GPU stacks, pre-loaded datasets  -  you can build and register your own template.

1. Write a `Dockerfile` for your image.
2. Build it using the custom sandbox template API (or the CLI: `miosa template build`).
3. Verify the image boots correctly.
4. Register the slug so it is selectable in `template_id`.

See the [Custom Templates API Reference](/docs/api-reference/sandboxes/) for the full endpoint spec, including image upload, smoke-test hooks, and versioning.

---

## BuildSpec primer

A **BuildSpec** is an optional JSON document you attach to a sandbox or Deployment to override the default install and start commands. It is the escape hatch for any template when defaults are not quite right:
```json
{
  "install": "pnpm install --frozen-lockfile",
  "build": "pnpm build",
  "start": "node .next/standalone/server.js",
  "env": {
    "NODE_ENV": "production",
    "PORT": "3000"
  }
}
```

Pass a BuildSpec at sandbox creation time or at publish time. Build-time commands (`install`, `build`) run inside the Builder; the `start` command determines how Runtime Instances are launched. Environment variables set here are merged with any variables already on the Deployment.

# Deploy from GitHub

URL: https://miosa.ai/docs/docker-host/deploy-from-github
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/deploy-from-github
Source: src/routes/docs/docker-host/deploy-from-github/+page.md
Description: Build and publish a GitHub repository with miosa deploy create --git - connect GitHub, public and private repositories, the branch, logs, redeploys, and the webhook that rebuilds on every push.

# Deploy from GitHub

`miosa deploy create --git` clones a repository, builds the branch you name, and publishes it at a stable URL.
The same deployment rebuilds when you push, once you add its webhook to the repository.

## Connect GitHub

A public repository needs no connection.
A private repository is cloned with the GitHub connection of the person who creates the deployment, so connect GitHub first:

```bash
miosa connections add apps github
```

The command opens GitHub's consent page and waits until you approve.
In the console the same connection is under **Connections**, **Apps**.

GitHub shows MIOSA only the organizations that approved it.
If an organization's repositories are missing, grant access on GitHub under **Settings**, **Applications**, **Authorized OAuth Apps**, or ask an organization owner to approve MIOSA.

## Deploy a repository

```bash
miosa deploy create --git https://github.com/octocat/Spoon-Knife --branch main
```

The command waits until the deployment is live and prints its URL, for example `https://spoon-knife.<your-org>.miosa.app`.
Pass `--name` to choose the deployment name; it defaults to the repository name.
Pass `--no-wait` to return as soon as the deployment is created.

Name the branch with `--branch`.
The deployment builds that branch now and on every push to it.

A private repository works the same way once GitHub is connected.
Without the connection, or with a branch that does not exist, the build fails at the clone step:

```text
publishing failed at build: The source could not be cloned (git exited 128). (SOURCE_CLONE_FAILED)
```

Connect GitHub, check the branch name, and run `miosa deploy redeploy <name>`.

## Logs and builds

```bash
miosa deploy builds my-app     # every build and its state
miosa deploy logs my-app       # why the last build failed, and the app's output
```

A static site has no runtime log: it serves the built files and runs no process.

## Redeploy

```bash
miosa deploy redeploy my-app
```

Redeploy builds the branch again from GitHub and releases it.
Use it after you fix a failed build, or to pick up a change without a push.

## Rebuild on every push

When `deploy create --git` creates the deployment, it prints a webhook secret once:

```text
Add this GitHub webhook so pushes redeploy (the secret is shown once):
  URL:          https://api.miosa.ai/api/v1/integrations/github/webhook
  Content type: application/json
  Secret:       <webhook secret>
  Events:       Just the push event
```

Add it to the repository under **Settings**, **Webhooks**, **Add webhook**, with exactly those values.
GitHub signs every delivery with the secret.
MIOSA checks the signature, finds the deployment for that repository and branch, and builds the pushed commit.
A delivery with no signature is refused with 401, and one with a wrong signature with 403.
Pushes to other branches are ignored.

The secret is also the `webhook_secret` field of the create response (`--json`).
Store it like a password: anyone with it can trigger a build.
To replace it, call `POST /api/v1/deployments/{id}/webhook-secret` and update the webhook on GitHub with the new value.

# The deployment model

URL: https://miosa.ai/docs/docker-host/deployment-model
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/deployment-model
Source: src/routes/docs/docker-host/deployment-model/+page.md
Description: How a publish becomes a stable production URL - the pipeline, static vs dynamic, deployments, versions, domains, and the proof contract.

# The deployment model

Every publish turns a Sandbox into a stable production app backed by immutable versions, health checks, and a public URL returned by the API.
This page explains the objects behind that flow and how they fit together.

## The deployment pipeline

Every publish travels the same path:

Diagram:
graph LR
    A[Sandbox] -->|publish| B[Source Snapshot]
    B --> C[Build]
    C -->|builds| D[Release]
    D -->|creates| E[Deployment Version]
    E -->|promotes| F[Static artifact, dynamic runtime or Docker Host container]
    F --> G[Domain]

1. **Sandbox**  -  the mutable environment where you (or an agent) write code.
2. **Source Snapshot**  -  an immutable tarball of `/workspace` captured at publish time. The sandbox can keep changing; the snapshot is frozen.
3. **Build**  -  MIOSA runs the configured build/packaging pipeline from the frozen source.
4. **Release**  -  the immutable build output. Static: files/assets. Dynamic: a server app artifact with command, port, and health check.
5. **Deployment Version**  -  the row in history. `version_number` increases monotonically. Every version is bootable forever.
6. **Runtime** - for dynamic deployments, MIOSA starts a production runtime and health-checks it. Static releases skip this; MIOSA serves the files directly. Docker Host releases run as containers on the workspace Docker Host.
7. **Domain** - the route. Managed, workspace-owned, tenant-owned, or exact custom domain. Rollback is re-pointing this route with no rebuild.

## Static vs Dynamic

| | Static | Dynamic | Docker Host |
|---|---|---|---|
| Source shape | HTML / JS / CSS / assets only | Server-side code | Many small workspace apps, funnels, APIs, client sites |
| Build output | Files/assets | Server app artifact | Container image from a release artifact |
| Production runtime | Static artifact serving, no per-app process | MIOSA dynamic runtime pool | Workspace Docker Host |
| Scaling | Instant file serving | Scheduler manages desired instance count | Multiple app containers on one workspace host |
| Rollback speed | Seconds | Seconds | Seconds after the replacement container is healthy |
| Best for | Landing pages, SPAs, generated HTML, docs | APIs, SSR, WebSockets, background workers | Multi-app workspaces and white-label app factories |

Pass `kind: "auto"` (or the SDK equivalent) and MIOSA chooses the static or dynamic path from your publish inputs. Supplying a run command and port makes the deployment dynamic.
Use Docker Host when you explicitly want the app to run inside the workspace Docker Host.

The recommended CLI path is:

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name <deployment> \
  --type docker_deploy \
  --wait \
  --json
```

Use the same `--name` on every publish so MIOSA creates a new version behind the same deployment ID and URL.

## The deployment object

A **Deployment** is the stable product object.
It is the thing the world thinks of as "the live app."
It has a name, a slug, an active version, and one or more domains pointing at it.

Diagram:
flowchart LR
  P[Project] --> D["Deployment<br/>team-portal"]
  D --> V17["active_version_id: Version 17<br/>Release sha:abc..."]
  D --> V16["Version 16<br/>archived, still bootable"]
  D --> V15["Version 15<br/>archived, still bootable"]
  D --> DM[domains]
  DM --> D1["team-portal.example-org.miosa.app<br/>managed fallback"]
  DM --> D2["team-portal.apps.example.com<br/>tenant deployment domain"]
  DM --> D3["example.net<br/>custom, verified"]
  D --> DA[data]
  DA --> PGS["postgres<br/>DATABASE_URL=..."]

A Deployment URL is **stable**. New publishes change which version it points at, not the URL itself.

## What gets versioned

| Thing | Versioned? |
|---|---|
| Source snapshot | Yes  -  sha256 of the tarball captured at publish time |
| Release artifact | Yes  -  sha256 of the static files or dynamic server artifact |
| Deployment Version | Yes  -  `version_number` monotonically increases |
| Domain ↔ version mapping | Yes  -  change history retained |
| Runtime Instances | Managed by scheduler against desired count; not versioned |
| Data Services | Not versioned  -  Postgres / Redis / buckets persist across deploys |

Rollback works because every release is immutable and stays in storage. Re-point the deployment at version 14 and MIOSA serves that known-good version again.

The active version remains live while a candidate builds and starts.
MIOSA changes production traffic only after the candidate passes its required checks.
If the candidate fails, the active version remains unchanged.

Use `kind: "static"`, `kind: "dynamic"`, or `kind: "auto"` for standard MIOSA Deploy.
Use Docker Host when the deployment should become a container on the workspace Docker Host.
The internal API value is still `docker_deploy` for compatibility.

## Proof contract

The deployment object is not the same thing as proof that production traffic is working.
For standard deployments, proof means the deployment has a public URL and MIOSA can route to the active release.
For Docker Host deployments, proof also requires the workspace host, durable app target, running container route, and public URL probe.

Use:

```bash
miosa deploy get <deployment-id> --json
miosa deploy requests <deployment-id>
```

# Docker Host

URL: https://miosa.ai/docs/docker-host/docker-deploy
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/docker-deploy
Source: src/routes/docs/docker-host/docker-deploy/+page.md
Description: Run many small apps on one always-on workspace host while MIOSA owns routing, domains, and attribution.

# Docker Host

Docker Host is MIOSA's dedicated workspace host model for customers that need many small apps, funnels, lead magnets, APIs, or client sites without creating a new production VM for every deployment.
It is the recommended production path for generated apps that should run 24/7 inside a workspace.
MIOSA keeps routing, domains, and attribution as the source of truth, and the host supplies the execution capacity.

## 1. Ensure the workspace host

```bash
miosa api POST /docker-deploy/hosts/ensure -d '{"workspace_id": "<workspace-id>"}'
miosa api GET /docker-deploy/hosts?workspace_id=<workspace-id>
```

The host moves from `provisioning` to `bootstrapping` to `active`. Publishes wait until it is active.

## 2. Publish an app

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --run-command "npm run start" \
  --port 3000 \
  --type docker_deploy \
  --wait \
  --wait-timeout 900s \
  --json
```

To publish a new version without changing the deployment URL, reuse the same `--name`.

## 3. Prove it

```bash
miosa deploy get <deployment-id> --json
```

A Docker Host deployment is live only when the host is active, the app target is running, the container route is reachable, and a probe to `public_url` succeeds.

# Deployment Domains

URL: https://miosa.ai/docs/docker-host/domains
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/domains
Source: src/routes/docs/docker-host/domains/+page.md
Description: Preview domains, tenant deployment domains, managed fallback URLs, exact custom domains, DNS verification, automatic TLS, and route changes.

A **Domain** is a hostname that routes to a preview, a deployment, a computer, or an exact custom resource. For production deployments, always use the `public_url` returned by the API. Do not reconstruct hostnames in SDKs, CLIs, or frontends.

## Domain layers

MIOSA keeps these layers separate:

| Layer | URL shape | Purpose |
|---|---|---|
| Sandbox preview domain | `https://{port}-{sandbox_slug}.sandbox.{preview_domain}` | Mutable live previews while an agent/user is editing |
| Tenant deployment domain | `https://{deployment_slug}.{deployment_domain}` | Branded durable URLs for generated production apps |
| Managed fallback domain | `https://{deployment_slug}.{organization_slug}.miosa.app` | Always-available MIOSA-managed fallback |
| Exact custom domain | `https://customer-owned.example.com` | A customer's chosen production domain attached to one deployment |
| Computer custom domain | `https://desktop.customer-owned.example.com` | A customer-owned hostname attached to one computer service |

Lumen is a made-up company, and `example.com` and `example.net` are reserved example domains.
Replace them with your own.

Lumen example:

```text
Sandbox preview:   https://5173-abc123.sandbox.example.com
Deployment domain: https://lead-magnet.apps.example.com
Managed fallback:  https://lead-magnet.example-org.miosa.app
Custom domain:     https://portal.example.net
```

Preview domains do not imply production deployment domains. Configure both if you want both surfaces branded.

## Tenant deployment domains

Tenant deployment domains are configured separately from preview domains. The backend resolves `settings["deployment_domain"]` for durable app URLs and falls back to `{organization_slug}.miosa.app` when no deployment domain is configured.

Public tenant-level management routes for deployment domains are not exposed yet. Operators can configure the tenant setting; SDKs and CLIs should treat deployment `public_url` / `url` as authoritative.

Recommended white-label DNS:

| Record type | Name | Value | Used for |
|---|---|---|---|
| `CNAME` | `*` | `proxy.miosa.ai` | Preview domain, including sandbox port previews |
| `CNAME` | `*.apps` | `proxy.miosa.ai` | Durable generated apps |

## Exact custom domains

Exact custom domains attach a customer-owned hostname to one deployment.
Exact custom domains are enabled by plan: Developer includes 3, Business 100 and Enterprise 500, with no support ticket. A Developer plan that has used all three gets `PLAN_LIMIT_REACHED` from the same check as any other cap.

| Kind | Example | DNS record |
|---|---|---|
| Subdomain | `app.example.net` | `CNAME` to the verification target |
| Apex | `example.net` | `A`/`AAAA`, `ALIAS`, `ANAME`, or flattened `CNAME` depending on DNS provider |
| WWW alias | `www.example.net` | `CNAME` to the verification target |

## The attach flow

```typescript
// 1. Register the exact domain. MIOSA returns DNS instructions.
const domain = await miosa.deployments.domains.add(deploymentId, {
  domain: "portal.example.net",
})

console.log(domain.dns_records)

// 2. After records are set, ask MIOSA to verify.
await miosa.deployments.domains.verify(deploymentId, domain.id)

// 3. Use the deployment public_url returned by the API.
const deployment = await miosa.deployments.get(deploymentId)
console.log(deployment.public_url)
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

domain = miosa.deployments.domains(deployment_id).add(
    domain="portal.example.net",
)

for record in domain.get("dns_records", []):
    print(record["type"], record["name"], record["value"])

miosa.deployments.domains(deployment_id).verify(domain["id"])

deployment = miosa.deployments.get(deployment_id)
print(deployment["public_url"])
```

```bash
curl -X POST https://api.miosa.ai/api/v1/deployments/$DEP/domains \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"portal.example.net"}'

curl -X POST https://api.miosa.ai/api/v1/deployments/$DEP/domains/$DOMAIN_ID/verify \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Once verified and TLS-active, MIOSA routes the exact domain to the deployment's active version. Exact custom domains take precedence over tenant deployment domains and MIOSA fallback URLs.

## Redirect policy

For apex + www domains, set the redirect policy:

| Policy | Result |
|---|---|
| `none` | Both apex and www serve independently |
| `apex_to_www` | `example.net` redirects to `www.example.net` |
| `www_to_apex` | `www.example.net` redirects to `example.net` |

Configure at attach time or update later via `PATCH /deployments/:id/domains/:domain_id`.

## What changing a domain does

Changing a domain mapping:

- Updates MIOSA's route table.
- Takes effect within seconds.
- Does **not** rebuild the app.
- Does **not** involve the source sandbox.
- Does **not** require users to change the deployment ID.

This is why rollback is fast: only the deployment's active version/route changes.

## DNS verification edge cases

| Situation | Behavior |
|---|---|
| CNAME points to the wrong host | Verification fails with `dns_target_mismatch`. Show the expected target. |
| TXT record not propagated yet | Verification fails with `dns_propagation_pending`. Retry after a few minutes. |
| User typos the domain | Verification fails with `dns_resolution_error`. Domain stays pending. |
| Domain already attached to another deployment in your tenant | `409 Conflict`. Detach from the other deployment first. |
| Domain attached to a different tenant | `403 Forbidden`. Contact support for transfer. |

## Provider input fields

DNS providers label the same fields differently.

Use the exact values MIOSA returns and translate only the field name:

| MIOSA instruction | Common provider labels | Example for `*.apps.example.com` |
|---|---|---|
| Record type | Type | `CNAME` |
| Host | Name, Host, Alias | `*.apps` |
| Target | Value, Points to, Destination | `proxy.miosa.ai` |
| TTL | TTL, Cache time | Automatic or 300 seconds |

Do not enter `https://`, a path, or a trailing slash in a DNS target.

Disable provider proxying until MIOSA reports that ownership and TLS verification are complete.

## Verification sequence

Diagram:
flowchart LR
  A["Register hostname"] --> B["Copy exact DNS records"]
  B --> C["Authoritative DNS answers"]
  C --> D["MIOSA verifies ownership"]
  D --> E["Certificate becomes active"]
  E --> F["Route serves active Version"]

If DNS resolves but the page still fails, continue with the [Recovery Playbooks](/docs/operations/recovery/) instead of changing records repeatedly.

## White-label checklist

For a platform like Lumen:

1. Configure the organization slug (`lumen`).
2. Configure preview DNS: a wildcard `CNAME` named `*` on `example.com`, pointing to `proxy.miosa.ai`.
3. Configure tenant deployment DNS, for example `*.apps.example.com`.
4. Publish generated apps and display the returned deployment `public_url`.
5. Attach exact customer domains only when a customer brings its own domain.

Preview domains, deployment domains, computer URLs, and exact custom domains are separate. Use the URL returned by the backend for each resource: `preview_url`, `desktop_url`, or deployment `public_url`.

## Set up a custom domain in the dashboard

Connect your own domain - for example `app.example.com` - so users land on your brand rather than a MIOSA fallback URL.

Go to **Settings → Domains** and click **+ Add custom domain**. The wizard walks you through three steps:

1. Enter your domain (`app.example.com`  -  no `https://`, no trailing path).
2. Add the DNS records shown to your domain provider.
3. Click **Continue to verify**  -  MIOSA checks your DNS and activates the domain.

You can also register the domain through the exact deployment or computer domain APIs before sending traffic; MIOSA returns the DNS records and verification status.

### Required DNS records

For wildcard preview or app domains, delegate traffic to MIOSA:

| Field | Value |
|---|---|
| Type | `CNAME` |
| Host | `*` (wildcard) |
| Value | `proxy.miosa.ai` |
| TTL | `300` - `600` seconds |
| Proxy status (Cloudflare only) | **DNS only**  -  gray cloud |

Replace `yourdomain.com` with the apex domain you own (e.g. `example.com` if your custom domain is `app.example.com`).

> **Apex domains** (no subdomain, e.g. `example.com` directly) additionally require an A/ALIAS record  -  add `_miosa-verify.example.com TXT <token>` as shown in the wizard.

If you're using Cloudflare as your DNS provider, make sure the wildcard CNAME has the proxy status set to **DNS only** (gray cloud), not **Proxied** (orange cloud). When proxied, Cloudflare terminates TLS itself and MIOSA never receives the request to issue a certificate  -  your sandbox URLs will fail with a TLS error. Other DNS providers (Route 53, Namecheap, GoDaddy, Porkbun) don't have this issue.

### TLS certificates and propagation

Certificates are provisioned automatically once DNS propagates. There is nothing to upload. You will see a valid `https://` certificate on first browser visit.

DNS changes typically take **5-30 minutes** but can take up to 48 hours depending on your provider's TTL settings.

To check current propagation status:

```bash
dig *.yourdomain.com CNAME +short
```

The expected result is `proxy.miosa.ai.`

Once configured and verified, MIOSA's router confirms the hostname belongs to your tenant, workspace, project, computer, or deployment, issues or reuses the TLS certificate, and routes the request to the current sandbox, computer, standard deployment, or Docker Host container. Domain ownership and tenant scope are checked before MIOSA routes traffic.

## Troubleshooting a routed domain

**Verification fails immediately after adding records**  -  DNS propagation is not instant. Wait a few minutes and click **Retry verification** in the wizard. The wizard polls every 5 seconds while open.

**`dig` shows the right value but verification still fails**  -  Some DNS providers add extra trailing dots or spaces. Ensure the CNAME value is exactly `proxy.miosa.ai` with no extra characters.

**Cache flush**  -  If the record still shows the old value, flush your local DNS cache:

```bash
# macOS
sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder

# Linux (systemd-resolved)
sudo systemd-resolve --flush-caches
```

Or check propagation from a neutral vantage point using [dnschecker.org](https://dnschecker.org).

**My sandbox URL returns a TLS error or cert warning**  -  DNS hasn't propagated yet, or (on Cloudflare) the proxy status is not **DNS only**. Confirm the record with `dig +short "*.your-domain.com" CNAME` (expected `proxy.miosa.ai.`).

**My sandbox URL returns 502 or 503**  -  Your sandbox isn't running, or no HTTP server is listening on the port you're requesting. The DNS chain is correct; the sandbox just needs to serve traffic.

**My sandbox URL returns 400 or "URL not connected"**  -  The slug doesn't match any sandbox in your tenant. Confirm the sandbox is in `running` state and that the slug (first 8 hex chars of the sandbox UUID) matches the leftmost label of the hostname.

## Branding

Once your domain is connected, customize the app name, logo, accent color, and favicon at **Settings → General → Branding**. The Domains page shows a live preview of what your users will see.

## Disconnecting

To stop using your custom domain: remove the CNAME from your DNS provider, or open **Settings → Domains** in MIOSA and click **Disconnect**. After disconnecting, the next request to `<slug>.<your-domain>` will fail to issue a certificate. The domain becomes available to bind to a different tenant after the cache expires.

# Environments

URL: https://miosa.ai/docs/docker-host/environments
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/environments
Source: src/routes/docs/docker-host/environments/+page.md
Description: Production, staging, preview/<source>: variable and secret scoping for deployments.

A **Deployment Environment** is the scope at which env vars, secrets, and data service bindings apply. Most projects have at least two: `production` and `staging`. Custom environments like `preview/feature-abc` are common for review-app workflows.

First-class `deployment_environments` records are part of the ongoing deployment refactor. Today, env vars are scoped per-deployment via `deployment_env_vars`. The shape and behavior here are the steady-state target.

## Defaults

Every project gets two environments at creation:

- `production`: what real users see
- `staging`: internal testing target before promoting to production

You can create additional environments (`preview/&lt;source&gt;`, `qa`, `canary`, etc.) as needed.

## What environments scope

| Item | Scope |
|---|---|
| Env vars | per environment |
| Secrets | per environment |
| Data service bindings (DATABASE_URL, REDIS_URL, etc.) | per environment |
| Domains | per environment (production gets the apex; staging gets a `staging.*` subdomain by convention) |
| Version promotion | per environment, promote a version to staging first, then to production |

The same deployment can run different versions in different environments. Common pattern:
```

production:   version 17 active
staging:      version 18 active   ← being tested
preview/pr-42: version 19 active  ← single-feature preview
```

## Env vars
```http
POST /api/v1/deployments/:id/env
GET  /api/v1/deployments/:id/env
```

Env vars are stored encrypted at rest (ChaCha20-Poly1305) and injected into the sandbox during development and into runtime instances at boot. The list endpoint returns previews of values, not the raw values, by default.

```typescript
await miosa.deployments.env.set(deploymentId, {
  environment: "production",
  vars: {
    STRIPE_KEY: "sk_live_...",
    NEXT_PUBLIC_API_URL: "https://api.example.net",
  },
})

const preview = await miosa.deployments.env.list(deploymentId, {
  environment: "production",
})
// preview returns: { STRIPE_KEY: "sk_live_••••", NEXT_PUBLIC_API_URL: "https://api…" }
```

```bash
curl -X POST https://api.miosa.ai/api/v1/deployments/$DEP/env \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{
    "environment": "production",
    "vars": { "STRIPE_KEY": "sk_live_..." }
  }'
```

## Secrets vs env vars

There's no strict UI distinction today: env vars are encrypted at rest regardless. The convention is:

- **Env vars**: configuration that can be retrieved as preview (truncated value).
- **Secrets**: same encryption, but marked `is_secret: true` so previews always show `••••` even to your own admins.

Future-state, secrets will support rotation and access-event audit logging.

## Data service bindings

When you create a Postgres / Redis / bucket via [Data](/docs/data/overview/), you bind it to a specific deployment environment. MIOSA injects the credential into env at boot:
```

production env:    DATABASE_URL=postgres://prod...
staging env:       DATABASE_URL=postgres://staging...
```

You don't ship two database URLs for one app; you ship one connection string variable, and MIOSA picks the right value based on which environment the runtime is booted in.

## Where to go next

- [Publishing](/docs/docker-host/publishing/): environments are picked at publish time
- [Domains](/docs/docker-host/domains/): attach a staging subdomain
- [Data](/docs/data/overview/): environment-scoped credentials

# Docker Hosts

URL: https://miosa.ai/docs/docker-host/hosts
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/hosts
Source: src/routes/docs/docker-host/hosts/+page.md
Description: How a workspace Docker Host works: lifecycle states, publishing flow, proof, updates, recovery, runtime boundary, and domains.

# Docker Hosts

A Docker Host host is the always-on workspace VM that runs Docker Host containers.
This page covers the host model, its lifecycle, how a publish reaches it, and how MIOSA proves the app is live.

## How it works

Diagram:
flowchart LR
    SB[Sandbox] --> REL[MIOSA release artifact]
    REL --> IMG[Docker image]
    IMG --> HOST[Workspace Docker Host]
    HOST --> APP1[Local app container]
    HOST --> APP2[Local app container]
    HOST --> APP3[Local app container]
    APP1 --> ROUTER[MIOSA router and domains]

When Docker Host is enabled for a workspace, MIOSA provisions one always-on Docker Host VM for that workspace. That host runs:

1. A white-labeled Docker Host portal for the workspace.
2. The private Docker Host control service.
3. One or more app containers created from immutable release artifacts.

The deployment still belongs to the MIOSA organization, workspace, project, and deployment records. The Docker host is execution capacity, not an authorization boundary.

Docker Host is not a label on a normal dynamic runtime.
For Docker Host publishes, MIOSA must wait for the workspace host and private agent to be ready before the deployment can be marked ready.
If the host is not active, the publish response stays pending instead of falling back to the standard runtime pool.

Docker Host apps are launched as isolated containers on the workspace host.
MIOSA records each app target durably so routing and recovery do not depend on transient process state.

## Host lifecycle

Create or inspect the workspace host before publishing customer apps:

```bash
miosa api POST /docker-deploy/hosts/ensure -d '{"workspace_id": "<workspace-id>"}'
miosa api GET /docker-deploy/hosts?workspace_id=<workspace-id>
```

The host moves through provisioning states until the Docker Host runtime is reachable and passes health checks.

| State           | Meaning                                                                                 |
| --------------- | --------------------------------------------------------------------------------------- |
| `provisioning`  | MIOSA is creating or starting the workspace Computer.                                   |
| `bootstrapping` | The portal and private deployment agent are being installed.                            |
| `active`        | The host is healthy and can accept Docker Host publishes.                                |
| `failed`        | MIOSA could not provision or bootstrap the host. Retry after fixing the reported issue. |

Each enabled workspace normally has one Docker Host. That host can run many app containers, and MIOSA still accounts deployments individually by organization, workspace, project, and deployment.

## Default URL behavior

Until a custom domain is attached, MIOSA returns a managed URL.
For a deployment in the OSA tenant, that can look like:

```text
https://my-app.osa.miosa.app
```

If the organization configures its own preview or deployment domain, workspace and project deployments can use that domain instead:

```text
intake.example.com
program.example.net
```

The exact URL is always returned by the publish/deploy response. Do not construct it in your app.
The effective URL hierarchy is:

1. Deployment custom domain.
2. Workspace deployment domain.
3. Tenant deployment domain.
4. MIOSA-managed tenant URL at `https://<deployment-slug>.<tenant-slug>.miosa.app`.

## Workspace and project scoping

Docker Host follows the same MIOSA attribution model as sandboxes and normal deployments:

Diagram:
flowchart TD
  Org[Organization] --> Workspace[Workspace]
  Workspace --> Project[Project]
  Project --> Sandbox[Sandbox]
  Project --> Deployment[Deployment]
  Project --> Domains[Domains]
  Project --> Data[Data services]

For multi-tenant products, pass your external IDs when creating workspaces, projects, sandboxes, and deployments. MIOSA stores those for billing, support, and customer mapping.

Lumen can create one workspace per customer or expert. Each workspace can have many projects and many sandbox-created deployments. Those deployments can stay on Lumen's managed domain or move to a customer-owned domain like `program.example.net`.

## Publishing to Docker Host

Use Docker Host when you want a sandbox artifact to run on the workspace Docker host instead of the standard dynamic runtime pool.

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --run-command "npm run start" \
  --port 3000 \
  --type docker_deploy \
  --wait \
  --wait-timeout 900s \
  --json
```

To publish a new version without changing the deployment URL, reuse the same `--name`.

The platform flow is:

1. Freeze the sandbox files into a release artifact.
2. Ensure the workspace Docker Host is active.
3. Upload the release to that workspace host.
4. Build the release into a Docker image.
5. Run the image as a local Docker container on the host.
6. Record the durable app target and runtime route.
7. Register MIOSA routing to the returned host port.
8. Return the live deployment URL.

If the host is still provisioning, the API returns `ready: false` instead of silently serving the app through a standard runtime.

## Proving Docker Host deployments

A Docker Host deployment is live only when all of these are true:

| Proof item | Required state |
| ---------- | -------------- |
| Deployment row | Exists and has `deployment_product: "docker_deploy"` |
| Host link | `docker_deploy_host_id` points to the workspace Docker Host |
| Host health | Host is active and reachable |
| App target | The deployment has a durable running Docker Host target |
| Container route | The active target has a reachable container route |
| Public URL | HTTP probe to `public_url` succeeds |

Use:

```bash
miosa deploy get <deployment-id> --json
```

## Updates and recovery

Every publish creates a candidate release.
MIOSA keeps the current healthy version serving until the candidate is built, started, health checked, routed, and promoted.
A failed candidate does not replace the live version.

Host maintenance can briefly interrupt apps on that host.
MIOSA preserves deployment records, release artifacts, domains, data bindings, and desired state while the host is updated.
Deployments that were running are reconciled and verified before the host returns to active service.

An intentionally stopped deployment remains stopped.
MIOSA does not treat a deliberate stop as a recovery target.

After maintenance, check the deployment's public contract and, for Docker Host, the host it runs on:

```bash
miosa deploy get <deployment-id> --json
miosa api GET /docker-deploy/hosts/<host-id>
```

## Runtime boundary

Docker Host uses two different host-side services:

| Service | Visibility                 | Purpose                                           |
| ------- | -------------------------- | ------------------------------------------------- |
| Portal  | User-facing, white-labeled | Shows the workspace deployment center.            |
| Agent   | MIOSA-private network only | Receives release artifacts and starts containers. |

Never expose the agent URL, Docker socket, host IP, or internal API key to browsers or customer code. SDKs, MCP tools, and customer apps should call MIOSA APIs; MIOSA talks to the workspace host.

## Domains

Domains can be set at several levels:

| Level        | Example                     | Use                                        |
| ------------ | --------------------------- | ------------------------------------------ |
| Organization | `example.com`              | Default customer preview/deployment domain |
| Workspace    | `acme.example.com`      | Client or expert workspace domain          |
| Deployment   | `program.example.net` | Exact app/site/funnel domain               |

MIOSA still verifies DNS, issues TLS, and routes traffic. The Docker Host only runs the app containers.

## What users see

Customers see MIOSA or your white-labeled product language. They should not see provider names, raw host IPs, Docker socket details, or internal agent URLs.

## API and SDKs

Use the Docker Host APIs when your app needs to prepare a workspace before a publish:

```text
GET  /api/v1/docker-deploy/hosts?workspace_id=<workspace-id>
POST /api/v1/docker-deploy/hosts/ensure
GET  /api/v1/docker-deploy/hosts/:id
```

The TypeScript and Python SDKs expose the same host operations. MCP tools are available for agents that need to check or ensure the workspace host before publishing.

# Docker Host

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/overview
Source: src/routes/docs/docker-host/overview/+page.md
Description: Your own always-on host that runs apps published from a sandbox, with immutable versions, health checks and rollback. Formerly App Engine.

# Docker Host

Docker Host (formerly App Engine) is a box of your own that runs the apps you publish from a sandbox.
For running a project's web services, workers, schedules and static sites, use [Services](/docs/services/overview) instead.

## Docker Host or Services?

| You want | Use |
|---|---|
| A web service, worker, schedule or static site in a project, with releases, variables, domains and rollback | [Services](/docs/services/overview) |
| An app published from a sandbox onto a host you run, with immutable versions | Docker Host (this section) |

Nothing here is removed.
The pages below describe the Docker Host deployment model.

Deploying on MIOSA means turning a Sandbox into a stable production app, site, or API backed by immutable versions, health checks, and a public URL returned by the API.
Once published, the deployment URL stays stable.
New publishes change which version it points at.

## 1. Publish from a sandbox

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name <deployment> \
  --type docker_deploy \
  --wait \
  --json
```

Use the same `--name` on every publish so MIOSA creates a new version behind the same deployment ID and URL.

```typescript
const result = await miosa.deployments.publish(deploymentId, {
  sourceSandboxId: sandbox.id,
  kind: "auto",                       // "static" | "dynamic" | "auto"
  environment: "production",          // "production" | "staging" | etc.
  outputPath: "/workspace",
  runCommand: "npm start",            // dynamic deployments only
  port: 3000,                         // dynamic only
})

console.log(result.deployment.public_url)
console.log(result.version.kind, result.version.state)
```

```python
result = miosa.deployments.publish(
    deployment_id,
    source_sandbox_id=sandbox_id,
    kind="auto",              # "static" | "dynamic" | "auto"
    environment="production",
    output_path="/workspace",
    run_command="npm start",         # dynamic only
    port=3000,                       # dynamic only
)

print(result.deployment.public_url)
print(result.version.kind, result.version.state)
```

## 2. Promote or roll back

```bash
miosa deploy releases <deployment>
miosa deploy promote <deployment> <release>
miosa deploy rollback <deployment> --to <release-id> --yes --json
```

Promotion and rollback each target one exact immutable release.

## 3. Prove it is live

```bash
miosa deploy get <deployment> --json
miosa deploy requests <deployment>
```

A deployment object is not proof by itself.
The public URL must route to the active release, and for Docker Host also to the workspace host and a running container.

# Publishing

Source: src/routes/docs/docker-host/publishing/+page.md
Description: Turn a Sandbox into an immutable Deployment Version. Source snapshots, build modes, static artifacts, dynamic runtimes, Docker Host containers, public URLs, and proof.

Publish is the moment a mutable sandbox becomes a frozen, reproducible artifact ready to serve production traffic.
The final runtime can be standard MIOSA Deploy or Docker Host.
The public URL always comes from MIOSA.

## The pipeline
Diagram:
flowchart LR
    SB[Sandbox] -->|freeze /workspace| SS[Source Snapshot]
    SS --> BLD[Build]
    BLD -->|compile + package| REL[Release]
    REL -->|referenced by| VER[Deployment Version]
    VER -->|promote| DEP[Deployment]
    DEP -->|standard deploy or Docker Host| DOM[Domain]

1. Sandbox /workspace          (mutable; agent or developer is editing here)
2. Source snapshot             (tarball, sha256-keyed, stored in object storage)
3. Build                       (static packager, auto-detect, or explicit commands)
4. Release                     (static artifact or dynamic server artifact, sha256-keyed)
5. Deployment Version          (database row pointing at the release)
6. Health check                (for dynamic; static skips this)
7. Promotion                   (Deployment.active_version_id updated)
8. Proof                       (route, runtime, and URL verified)

The sequence below shows who acts at each step:

Diagram:
sequenceDiagram
    participant YC as Your Code
    participant M as MIOSA

    YC->>M: publish sandbox to new or existing deployment
    M-->>YC: 202 Accepted (build in progress)
    M->>M: freeze /workspace → source snapshot
    M->>M: compile + package → release artifact
    M->>M: create Deployment Version row
    M->>M: health check (dynamic only)
    M->>M: promote  -  Deployment.active_version_id updated
    M-->>YC: version.state = ready, public_url live

You make one publish request.
MIOSA does all of this internally and returns the result when the version reaches a terminal state.
For Docker Host, MIOSA also ensures the workspace host, starts the app container, and proves the route before the deployment is treated as live.

## The publish call

Create the deployment from a tested sandbox:

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --type docker_deploy \
  --wait \
  --json
```

Publish the next version to that same deployment:

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name <deployment> \
  --dir /workspace \
  --type docker_deploy \
  --wait \
  --json
```

The second command preserves the deployment ID and canonical URL.
It creates a new immutable candidate and promotes it only after verification succeeds.

```typescript
const result = await miosa.deployments.publish(deploymentId, {
  sourceSandboxId: sandbox.id,
  kind: "auto",                       // "static" | "dynamic" | "auto"
  environment: "production",          // "production" | "staging" | etc.
  outputPath: "/workspace",
  buildCommand: "npm run build",      // optional; auto-detected if omitted
  runCommand: "npm start",            // dynamic deployments only
  port: 3000,                         // dynamic only
  healthCheckPath: "/_health",        // dynamic only
  externalWorkspaceId: "acct-123",
  externalUserId: "user-456",
  externalProjectId: "landing-page-789",
})

console.log(result.deployment.public_url)
console.log(result.version.kind, result.version.state)
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

result = miosa.deployments.publish(
    deployment_id,
    source_sandbox_id=sandbox_id,
    kind="auto",              # "static" | "dynamic" | "auto"
    environment="production",
    output_path="/workspace",
    build_command="npm run build",   # optional; auto-detected if omitted
    run_command="npm start",         # dynamic only
    port=3000,                       # dynamic only
    health_check_path="/_health",    # dynamic only
    external_workspace_id="acct-123",
    external_user_id="user-456",
    external_project_id="landing-page-789",
)

print(result.deployment.public_url)
print(result.version.kind, result.version.state)
```

```bash
curl -X POST https://api.miosa.ai/api/v1/deployments/$DEP/publish \

  }'
```

Response shape:
```json

  "data": {
    "deployment": {
      "id": "dep_...",
      "active_version_id": "ver_...",
      "state": "running",
      "public_url": "https://team-portal.apps.example.com"
    },
    "version": {
      "id": "ver_...",
      "kind": "static",
      "state": "ready",
      "artifact_sha256": "...",
      "source_sha256": "..."
    },
    "services": [
      { "id": "svc_...", "type": "static_web", "state": "healthy" }
    ],
    "promoted": true
  }
}
```

## Source snapshots

Before the builder runs, MIOSA freezes a snapshot of the sandbox's source. The snapshot is a tarball of `/workspace` (or whatever `output_path` you specify), excluding cache directories that don't need to ship:
```

included:    application code, package manifests, lockfiles, public assets, config
excluded:    node_modules, .next/cache, dist (will be rebuilt), .git (unless needed),
             __pycache__, build/, target/
```

The snapshot is stored and sha256-keyed. The version record stores `source_sha256` so retries can rebuild from the exact same input without re-snapshotting.

The sandbox keeps running while the build runs. You can keep editing.

## Build modes

MIOSA picks a build mode from the source. You can override with `build_command` if needed.

| Mode | Trigger | What happens |
|---|---|---|
| **Dockerfile** | `Dockerfile` exists in `output_path` | MIOSA builds the container-style server artifact |
| **Auto-detect** | `package.json` / `requirements.txt` / `pyproject.toml` / `go.mod` / `mix.exs` | MIOSA picks install/build/start defaults |
| **Static packager** | Only static files in output (no server entrypoint detected) | Files are stored as a static release |
| **Explicit** | `buildCommand` and/or `runCommand` provided | MIOSA runs those, then packages whatever's in `output_path` |

Do not construct production URLs in your SDK, CLI, or frontend. Read `data.deployment.public_url` or `data.url` from the publish response and display that exact value. Tenants can use a deployment domain, MIOSA fallback, or an exact custom domain.

## Docker Host publish

Use Docker Host for workspaces that publish many small apps, funnels, lead magnets, APIs, or client sites.
The app runs as a container on the workspace Docker Host, while MIOSA owns routing, TLS, domains, billing attribution, and the Deployment record.

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --run-command "npm run start" \
  --port 3000 \
  --type docker_deploy \
  --wait \
  --wait-timeout 900s \
  --json
```

For an update, reuse the deployment `--name`.
This targets the existing deployment instead of creating another one.

Then check the deployment:

```bash
miosa deploy get <deployment-id> --json
miosa deploy requests <deployment-id>
```

The command name and API path still contain `docker-deploy` because that is the compatibility wire value.
Customer-facing product language is Docker Host.

## What gets promoted, and when

Static publishes promote as soon as the artifact is uploaded  -  there's nothing to health-check.

Dynamic publishes don't promote until:

1. The build succeeded.
2. The dynamic release artifact was stored.
3. New production runtimes were scheduled.
4. Health checks (`GET healthCheckPath`) returned 2xx for the configured grace period (default 30s healthy before promotion).

If health checks fail, the **previous version stays live** and the new version is marked `failed`. No traffic is sent to the broken release. Your last known good production keeps serving.

## Idempotency

Pass `Idempotency-Key` on every publish. If the same key is sent twice within the retention window, MIOSA returns the original result without re-building. This makes retries safe  -  useful for shaky network connections and worker queues.

## Failure modes

| Failure | What happens | Recovery |
|---|---|---|
| Build command exits non-zero | Version marked `failed`, log uploaded, production unchanged | Fix in sandbox, publish again |
| Health check never passes | Version marked `failed`, runtime instances torn down | Fix run command or healthCheckPath, publish again |
| Docker Host is not active | Publish waits or returns not ready | Run `miosa api POST /docker-deploy/hosts/ensure`, then publish again |
| Docker Host app row is missing | The deployment is not routable | Re-publish with `--type docker_deploy --wait`, then check again |
| Source snapshot fails | Publish returns 5xx immediately, no version row created | Retry the request |
| Static build exceeds artifact size limit | Version marked `failed` | Reduce assets or contact support to raise limit |
| Two publishes race for the same deployment | Second one waits on the advisory lock; both eventually succeed in order | None  -  handled automatically by our operation lock |

# Releases

URL: https://miosa.ai/docs/docker-host/releases
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/releases
Source: src/routes/docs/docker-host/releases/+page.md
Description: The immutable build artifact: static files or dynamic server artifact, sha256-keyed.

A **Release** is the immutable artifact produced by a build. Versions reference releases; static deployments serve files from them and dynamic deployments start runtimes from them.

You typically don't address releases directly through the API. They're an implementation detail of `Deployment Version`. But it's useful to know they exist as their own record because they're what makes rollback and horizontal scaling work.

Most integrations do not need to read release records directly. Use deployment versions and the returned deployment `public_url` unless you are building an operator dashboard or audit workflow.

## Release kinds

| Kind | Used by | Storage |
|---|---|---|
| `static` | Static deployments | Built files and assets |
| `oci` | Dynamic deployments via OCI-compatible workflows | Server image artifact |
| `dynamic` | Server apps with a run command and port | Packaged server artifact |

The release format determines how the deployment is served:

- **Static releases** → MIOSA's static artifact server streams files from object storage directly. No per-app process runs.
- **Dynamic releases** → MIOSA starts healthy production runtimes and routes traffic to them.

## Immutability

Releases are content-addressed by sha256. A release with sha256 `abc...` is always the same bytes, anywhere it's referenced. This is what makes:

- **Rollback** trivial: repoint a domain at an older version, which still references its release.
- **Scaling** trivial: schedule N copies of the same release on N hosts; every instance is byte-identical.
- **Audit** clean: the release that served traffic at time T can be reproduced from its hash.

A release is never mutated after creation. To "change" it, publish a new version, which produces a new release.

## Where releases live

Releases are stored and served by MIOSA. You can inspect release metadata on the version record:
```json
{
  "version_number": 17,
  "artifact_sha256": "a5e6f0c1...",
  "artifact_manifest": {
    "files": 42,
    "total_bytes": 184320,
    "entrypoint": "index.html"
  }
}
```

You do not need to download releases yourself. The metadata is shown for debugging and audit.

## Source snapshot vs release

These are two different artifacts in the same build:

| Artifact | What it is | Sha256 stored on |
|---|---|---|
| **Source snapshot** | Frozen tarball of the sandbox source at publish time | `version.source_sha256` |
| **Release** | The built output | `version.artifact_sha256` |

The source snapshot exists so retries / rebuilds are reproducible. The release exists so production can be served and scaled.

## Garbage collection

Static release artifacts older than the retention window (default 30 days for archived versions) may be garbage-collected. The version row remains for audit; if you attempt to rollback to a version whose artifact has been GC'd, MIOSA returns 410 Gone.

Active versions (`active_version_id` on any deployment) are never GC'd, even past retention.

# Rollback

URL: https://miosa.ai/docs/docker-host/rollback
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/rollback
Source: src/routes/docs/docker-host/rollback/+page.md
Description: Repoint a deployment at an older version. Seconds, no rebuild.

Rollback on MIOSA is fast because nothing has to be rebuilt. The previous release is still in storage. Runtime instances boot quickly. Static artifacts are streamed from object storage. The whole operation is "change one row, propagate to the edge cache."

## When you'd rollback

- New version passed health checks but the app is broken in real traffic (e.g. a feature flag mis-fire).
- A bad migration deployed.
- A regression you missed in staging.
- Hostile incident: quick revert while you investigate.

## How fast

| Step | Static | Dynamic |
|---|---|---|
| Update active version | `&lt;1s` | `&lt;1s` |
| Edge route cache refresh | `&lt;60s default` | `&lt;60s default` |
| New runtime instances spawn? | n/a (no per-app process) | Only if older version's instances were torn down; the scheduler boots replacements |
| Drain old runtime instances | n/a | Only if rolling forward, not on rollback |
| **Total wall clock** | **seconds** | **seconds to ~1 minute** |

If the older version's runtime instances are still healthy (recent rollforward where the old instances haven't been torn down yet), dynamic rollback is also instant: the router switches backends without any VM boots.

## How rollback works

    participant C as Client
    participant API as Deployments API
    participant DB as active_version_id

    API->>DB: UPDATE active_version_id = version_id

    E-->>E: reload route table (<60s)
    API->>RI: confirm healthy instances for old version
    RI-->>API: instances ready
    API-->>C: deployment with new active_version_id

## API

```typescript
// Easy form: roll back to the previous version
await miosa.deployments.rollback(deploymentId)

// Explicit form: roll back to a specific version
await miosa.deployments.rollback(deploymentId, {
  versionId: "ver_01H...",
})
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Easy form: roll back to the previous version
deployment = miosa.deployments.rollback(deployment_id)

# Explicit form: roll back to a specific version
deployment = miosa.deployments.rollback(
    deployment_id,
    version_id="ver_01H...",
)

print(deployment.active_version_id)
print(deployment.state)
```

```bash
# Rollback to a specific version
curl -X POST https://api.miosa.ai/api/v1/deployments/$DEP/rollback \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -d '{"version_id":"ver_01H..."}'
```

Server behavior:
```

1. Validate target version_id belongs to this deployment
2. Validate target version state === "ready" (cannot rollback to failed)
3. Validate target version's release artifact still exists in storage
   (returns 410 Gone if GC'd)
4. UPDATE deployments SET active_version_id = $version_id
5. Invalidate edge route cache
6. For dynamic: confirm enough healthy instances for the old version; spawn if needed
7. Return the deployment with the new active_version_id
```

Response:
```json
{
  "data": {
    "id": "dep_...",
    "active_version_id": "ver_01H...",
    "state": "running",
    "public_url": "https://team-portal.example-org.miosa.app"
  }
}
```

## Picking the rollback target

Use the [Versions](/docs/docker-host/versions/) API to inspect candidates:
```typescript
const versions = await miosa.deployments.versions.list(deploymentId, {
  state: "ready",
  limit: 10,
})

// Find the last known good version
const target = versions.data.find(v => v.id !== deployment.active_version_id)
```

For production, picking the immediately-previous version is usually correct. For incidents, you may need to go further back if multiple recent versions share the bug.

## Rolling forward after rollback

After a rollback, the version you rolled back FROM is still in `ready` state (unless you explicitly archive it). You can re-promote it later if it turns out the issue wasn't in the code:
```typescript
await miosa.deployments.versions.promote(deploymentId, originalVersionId)
```

This is a regular promotion, not a rollback. The path is symmetric.

## What rollback doesn't fix

| Issue | Why rollback doesn't help |
|---|---|
| Bad database migration | The database is *outside* the version. Roll back the schema separately or restore from backup. See [Postgres](/docs/data/postgres/). |
| Bad managed-data state | Same: data services persist across version changes by design. |
| External service config drift | Stripe webhooks, OAuth callbacks, and similar: not part of the release. |
| Already-served bad responses | Already in your customers' browsers / caches. Bust caches separately. |

Rollback fixes code; it does not fix state. Plan migrations to be backward-compatible (`expand → migrate → contract`) so older versions keep working after a forward migration.

## Idempotency

Rollback requests carry an `Idempotency-Key` header. Identical keys within the retention window return the original result without re-running the operation. This matters during incidents when retry storms are common.

## Audit

Every rollback emits an audit event with:

- The previous `active_version_id`
- The target version_id
- The user / API key that performed it
- The `Idempotency-Key`
- External attribution

Audit events are queryable through the platform audit API and are retained per the tenant's plan.

# Dynamic Runtimes

URL: https://miosa.ai/docs/docker-host/runtime-instances
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/runtime-instances
Source: src/routes/docs/docker-host/runtime-instances/+page.md
Description: Dynamic deployments: production runtimes started from a release, health-checked, and reconciled by MIOSA.

A **Runtime Instance** is a running production runtime that serves a dynamic deployment. Static deployments do not have runtime instances; they are served from immutable static artifacts.

The caller-facing contract is stable: dynamic deployments start production runtimes, wait for health checks, and only promote when the new version is ready. You do not need to know how MIOSA places or reconciles those runtimes.

## What a runtime instance is

A runtime started from the customer's release. The release is the customer's app, fully packaged. The runtime:

1. Boots in under a few seconds.
2. Receives `PORT` (the release port, unless you set your own), `DATABASE_URL`, `AUTH_URL`, and other env vars injected by MIOSA at boot.
3. Starts the configured `run_command`.
4. Listens on `port`.
5. Responds to `GET health_check_path` with 2xx.
6. Joins the deployment's backend pool; the router starts sending it traffic.

When a runtime instance dies (crash, host failure, configured restart), MIOSA's reconciler notices and schedules a replacement on another healthy host.

## Where it runs

Each runtime instance runs in its own microVM on a MIOSA-managed host.
Runtimes of different customers are segmented from each other on the network, and a runtime can reach only the services you have linked to it plus the public internet.
A restart of the host's agent does not stop a running instance.
The agent reattaches to it when it comes back.

## The port your app must use

MIOSA sets `PORT` to the release's port (the service `port`, `8080` by default) unless you set `PORT` yourself in the deployment's env vars.
Your app must listen on that port on all interfaces (`0.0.0.0`), not only on `127.0.0.1`.
MIOSA reaches it from inside the microVM and publishes it at the instance's address.
The address and port the API reports for an instance are where MIOSA's router reaches it, and are not always the runtime's private address.

## Next.js apps

Set `output: "standalone"` in `next.config`.
When the build produces `.next/standalone/server.js`, MIOSA copies `public` and `.next/static` beside it and runs:

```bash
HOSTNAME=0.0.0.0 node .next/standalone/server.js
```

A standalone release carries its own traced `node_modules`, so MIOSA does not reinstall dependencies in the runtime.
Without standalone output, a Next.js app starts with `next start` and needs the full build.

## Build output is required

A Next.js release must contain its production build: `.next/BUILD_ID` has to exist in the release.
A release that is only the source tree cannot run, because `next start` stops at once with `Could not find a production build`.
MIOSA refuses such a release at publish time and again at start time, with the error `build_output_missing`.
Fix it by running the build before the release is created, or by letting MIOSA build the app, and publish again.

## When a start fails

A runtime instance start fails, and the instance is removed, when any of these happens:

| Error | Meaning |
|---|---|
| `release_install_failed` | Downloading, verifying or unpacking the release failed. The error carries the exit code and the last output of the step. |
| `build_output_missing` | A Next.js release has no production build (see above). |
| `app_launch_failed` | The start command could not be launched. |
| `app_not_listening` | The app started but did not answer its health check on its port. |

For `release_install_failed`, `app_launch_failed` and `app_not_listening`, the deployment's error message includes the tail of the app's log, the processes running in the runtime, and the ports it is listening on, so you can see why it did not come up.
Read it first: the usual causes are an app that binds `127.0.0.1` instead of `0.0.0.0`, a wrong `port`, a missing dependency, or a missing build.
Because the failed instance is removed, a start that fails never serves traffic and the previous version stays live.

## What you control vs what MIOSA controls

| You | MIOSA |
|---|---|
| Release contents (your code + dependencies) | Where to schedule instances |
| `run_command` and `port` | When to start / stop / replace instances |
| `health_check_path` | Routing healthy instances to traffic |
| Desired replica count (eventually; defaults to 1) | Boot-time env var injection |
| Env vars set on the deployment | Telemetry, logs streaming |

You don't pick a host directly. MIOSA's scheduler matches your workload's requirements (CPU, RAM, region) against the fleet's free capacity.

## Lifecycle

- `pending`: scheduled, not yet booting.
- `starting`: VM is booting; health check not yet passing.
- `healthy`: serving traffic.
- `unhealthy`: failing health checks; router has removed it from the pool. Reconciler decides whether to restart or replace.
- `stopping` / `stopped`: deliberately torn down.
- `failed`: terminal, having exceeded the crashloop budget. Reconciler stops trying.

## Health checks and the grace period

When a runtime instance starts, it has a configurable grace period (default 60s) to become healthy. During grace, repeated 5xx / connection-refused are tolerated.

After grace, the health check is enforced strictly:

- 3 consecutive failures → instance marked `unhealthy`, removed from routing.
- If a replacement is needed and starts healthily, the old instance is torn down.
- Repeated rapid failures invoke crashloop backoff: 1s → 2s → 5s → 30s → 5min between restart attempts.

## Blue/green during publish

When you publish a new dynamic version, MIOSA does NOT terminate the existing healthy instances first. The sequence is:

1. Start new runtime instances from the new release.
2. Wait until enough new instances pass health checks.
3. Update the router so the deployment's hostname points at the new instances.
4. Drain (stop accepting new connections) and tear down old instances after old in-flight requests complete.

If step 2 never succeeds, step 3 never runs. The old version stays live, the new version is marked `failed`.

## Replicas

By default, a dynamic service has 1 replica. Increase by setting `desired_replicas` on the service. The reconciler spreads replicas across hosts and across availability zones where possible.
```typescript
await miosa.services.update(serviceId, { desiredReplicas: 3 })
```

Traffic load-balances across all healthy replicas in round-robin (or hash-based if sticky sessions are configured).

## Resource sizing

| Spec | Default | Tunable per service |
|---|---|---|
| CPU | 1 vCPU | yes |
| Memory | 512 MB | yes |
| Disk | 1 GB ephemeral | yes |
| GPU | none | not available (GPU is not productized) |
| Outbound bandwidth | metered | yes |

Sizing is per-service, per-deployment. A worker service can be smaller than a web service.

## Logs

Runtime instances stream stdout/stderr to MIOSA's log plane. Logs are retained per the tenant's plan (default 7 days). Access them through:

- `GET /api/v1/deployments/:id/logs`: deployment-scoped, all services
- `GET /api/v1/services/:id/logs`: per-service
- `GET /api/v1/runtime-instances/:id/logs`: per-instance

Logs include structured metadata: `service_id`, `runtime_instance_id`, `version_id`, `host_id`. Filter by `external_workspace_id` to scope to a white-label customer.

Description: Curated app shapes for Docker Host - Dockerfile, Compose, command, port, environment, and persistence defaults.

# Docker Host templates

Docker Host templates are curated app shapes for agents, SDKs, and the UI. They do not replace your project code. They provide Dockerfile, Compose, command, port, environment, persistence, and design-context defaults before a sandbox or repository is published.

| Template                      | Best for                                          | Runtime        |
| ----------------------------- | ------------------------------------------------- | -------------- |
| Next.js App                   | SaaS portals, dashboards, client apps             | Node           |
| Next.js Funnel / Landing Page | funnels, lead magnets, campaign sites             | Node           |
| Vite React SPA                | static React apps, calculators, widgets           | Nginx          |
| Express / Node API            | webhooks, integrations, lightweight APIs          | Node           |
| FastAPI Service               | Python APIs, AI helper services, data tools       | Python         |
| Static HTML Site              | documents, one-page tools, static downloads       | Nginx          |
| Compose Full-Stack App        | web + API + worker + Postgres + Redis on one host | Docker Compose |

Template metadata is returned by:

```text
GET /api/v1/docker-deploy/templates
GET /api/v1/docker-deploy/templates/:id
```

Use a template id as metadata when creating a deployment so the deployment center can show the intended build shape and recover the defaults later:

```json
{
  "deployment_product": "docker_deploy",
  "metadata": {
    "docker_deploy_template_id": "compose-full-stack"
  }
}
```

# Versions

URL: https://miosa.ai/docs/docker-host/versions
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/docker-host/versions
Source: src/routes/docs/docker-host/versions/+page.md
Description: Immutable history of every publish. Inspect, promote, archive.

Each successful publish produces a **Deployment Version**. Versions are immutable: the source hash, artifact hash, build log, and runtime config are frozen at creation. Versions never change after they're written.

How Deployments, Versions, and Releases relate:

Diagram:
graph TB
    DEP[Deployment team-portal] -->|active_version_id| V3[Version v3 - active]
    DEP -->|history| V2[Version v2 - archived]
    DEP -->|history| V1[Version v1 - archived]
    V3 -->|artifact_uri| R3[Release sha256:abc]
    V2 -->|artifact_uri| R2[Release sha256:def]
    V1 -->|artifact_uri| R1[Release sha256:ghi]

## Version shape
```json
{
  "id": "ver_01H...",
  "deployment_id": "dep_01H...",
  "tenant_id": "...",
  "created_by": "user_...",
  "external_workspace_id": "acct-123",
  "external_user_id": "user-456",
  "external_project_id": "landing-page-789",
  "source_sandbox_id": "sbx_...",
  "build_id": "bld_...",
  "version_number": 17,
  "kind": "static",
  "state": "ready",
  "artifact_uri": "s3://miosa-releases/dep_.../ver_.../dist.tar.zst",
  "artifact_manifest": { "files": 42, "total_bytes": 184320, "entrypoint": "index.html" },
  "artifact_sha256": "a5e6f0c1...",
  "runtime_image": null,
  "runtime_command": null,
  "runtime_port": null,
  "health_check_path": null,
  "build_log_uri": "s3://miosa-logs/builds/bld_.../log.txt",
  "metadata": { },
  "promoted_at": "2026-05-14T18:20:00Z",
  "archived_at": null,
  "created_at": "2026-05-14T18:19:48Z",
  "updated_at": "2026-05-14T18:20:00Z"
}
```

For dynamic versions, the `runtime_image`, `runtime_command`, `runtime_port`, and `health_check_path` fields are populated; for static they're null.

## States

| State | Meaning |
|---|---|
| `created` | Row exists, build not started |
| `building` | Build in progress |
| `ready` | Build succeeded, artifact uploaded, can be promoted |
| `failed` | Build failed or health checks didn't pass; not promotable |
| `archived` | Promoted-out-of; still bootable for rollback |

`state` transitions are one-way (no `ready → failed` after the fact); once a version is `ready`, it stays bootable until explicitly garbage-collected.

## Endpoints
```http
GET    /api/v1/deployments/:id/versions
GET    /api/v1/deployments/:id/versions/:version_id
POST   /api/v1/deployments/:id/versions/:version_id/promote
POST   /api/v1/deployments/:id/rollback
```

### List versions

```typescript
const versions = await miosa.deployments.versions.list(deploymentId, {
  limit: 50,
  state: "ready",
})

for (const v of versions.data) {
  console.log(v.version_number, v.kind, v.state, v.artifact_sha256.slice(0, 8))
}
```

```bash
curl https://api.miosa.ai/api/v1/deployments/$DEP/versions?state=ready \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

### Promote a specific version

Useful for staged rollouts: publish without auto-promote, manually promote when ready.

```typescript
const result = await miosa.deployments.versions.promote(deploymentId, versionId)
console.log(result.deployment.active_version_id) // === versionId
```

```bash
curl -X POST https://api.miosa.ai/api/v1/deployments/$DEP/versions/$VER/promote \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Requires `deployments:write` scope. Listing/showing requires `deployments:read`.

## Versions and external attribution

Every version inherits attribution from the source sandbox or the publish call. Filtering versions by `external_workspace_id` shows all versions any of your external workspaces published, scoped to your MIOSA tenant.
```typescript
const acmeVersions = await miosa.deployments.versions.list(deploymentId, {
  externalWorkspaceId: "acme-team-123",
})
```

This is how white-label platforms expose a "deploy history" view per end-customer in their own UI.

## How long are versions kept?

`ready` versions are kept for at least 30 days by default. Archived versions older than that are eligible for garbage collection of their release artifacts; the version row itself stays for audit. Long-term storage policies are configurable per tenant. Contact support if you need a different retention.

# Evaluations

URL: https://miosa.ai/docs/evaluations
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/evaluations
Source: src/routes/docs/evaluations/+page.md
Description: Measure sandbox, desktop, and agent workflows with reproducible tasks, traces, and desktop-readiness benchmarks.

# Evaluations

Evaluations help you answer a simple question: is your agent actually getting work done on a real computer or sandbox, and how long does the work take?

MIOSA evaluations cover three layers:

| Layer | What it measures |
|---|---|
| **Sandbox workflow** | create, write files, run commands, expose a preview, publish, and clean up |
| **Desktop workflow** | boot a Computer, open a browser, screenshot, click, type, scroll, and observe the result |
| **Agent task** | give an agent a goal, collect the trace, score whether the final state matches the expected outcome |

The public docs describe the measurement model, task shape, and customer-facing outputs. The internal runner, scheduling, and scoring implementation are intentionally abstracted.

## Why evaluations matter

For app-builder products and computer-use agents, normal API uptime is not enough. You need to know:

- How quickly a workspace becomes usable.
- Whether the desktop stream is ready before the agent acts.
- Whether screenshots and actions stay responsive during real tasks.
- Whether a generated app can move from prompt to preview to publish.
- Whether a model, tool loop, or provider change improves task success.

## OSWorld-compatible benchmark direction

OSWorld is a public benchmark for multimodal agents in real computer environments. It defines real desktop tasks, setup state, agent interaction, and execution-based scoring across open-ended workflows. The public OSWorld site describes 369 real-world computer tasks, with 361 tasks commonly used when excluding Google Drive tasks that need manual configuration.

MIOSA uses the same idea for product benchmarking:

- Start from a known computer state.
- Run a task through screenshot and action APIs.
- Capture every observation and action.
- Score the final state with a deterministic evaluator where possible.
- Save the trace so failures can be replayed and compared.

## Evaluation flow

Diagram:
flowchart LR
  A[Task suite] --> B[Provision sandbox or computer]
  B --> C[Run agent loop]
  C --> D[Capture trace]
  D --> E[Score result]
  E --> F[Report success, latency, and cost]

## Desktop readiness metrics

These are the computer desktop metrics we track for V1 quality:

| Metric | Why it matters |
|---|---|
| **Provision time** | Time from create request to assigned machine. |
| **Desktop ready** | Time until the desktop stream accepts a real connection. |
| **First screenshot** | Time until the agent can observe the screen. |
| **First action** | Time until click, type, or key events are accepted. |
| **Screenshot latency** | Round-trip time for repeated screenshots during a task. |
| **Action latency** | Round-trip time for click, type, scroll, and key events. |
| **Task success** | Whether the final desktop state matches the evaluator. |
| **Trace completeness** | Whether every observation and action is captured for replay. |

## Sandbox workflow metrics

For AI app builders, the main path is:

1. Create a sandbox.
2. Write generated files.
3. Install and run the app.
4. Expose a live preview.
5. Iterate on feedback.
6. Publish to a durable deployment.
7. Destroy or pause the workspace.

MIOSA tracks timing and failure rates across that whole path, not just isolated endpoint latency.

## What customers see


    Success rate, total time, p50 and p95 latency, failed step, and resource usage.



    Screenshots, commands, preview URLs, action events, and final result state.



    Compare native MIOSA Computers, BYOC machines, and external providers through one task shape.



    Re-run the same task suite after image, SDK, agent, or provider changes.


## V1 scope

| Capability | Status |
|---|---|
| Desktop readiness benchmark | Available as a V1 quality target. |
| OSWorld-style task scoring | In hardening for partner use. |
| Public leaderboard | Planned after the runner and reporting format stabilize. |

## Use cases

- Validate that a Lumen lead magnet builder can create, preview, and publish a generated app.
- Compare two agent prompts against the same browser task.
- Check whether a desktop image change affected first screenshot time.
- Prove that a full-stack app builder still works after SDK or deploy changes.

# Agents

Short answers on agent harnesses, model keys, and where agents run.

`claude-code`, `codex`, `osa`, and `custom`, set with `miosa agent new --harness`.
Agent Run providers also include `claude`, `pi`, and `hermes`.
See [Agents CLI](/docs/cli/agents/) and [Configure an agent](/docs/guides/configure-agent/).

```bash
miosa agent new reviewer --harness claude-code --instructions-file review.md
miosa agent run reviewer "review PR 42" --sandbox my-box
miosa run list                 # follow, stop
```

See [Agents CLI](/docs/cli/agents/).

OSA is MIOSA's open-source agent.
It installs on your machine, runs as an MCP client, and runs headless with `osa run "..."` when you do not want the terminal UI.
See [MCP](/docs/mcp/) and the [CLI reference](/docs/cli/).

No. Agents use your own model connections, never MIOSA platform keys.
Create an agent-scoped key and add a model connection before the first run.
See [Agents CLI](/docs/cli/agents/).

Agents work against a device: a Sandbox Worker, a Computer, or a local/BYOC device.
Docker Host is a hosting target, not an agent device.
See [Agent devices](/docs/guides/agent-devices/) and [Choose an agent device](/docs/guides/agent-device-selection/).

Yes. Call the primitives from your own backend, or start with the [Agent Development Kit (ADK)](/docs/adk/).

Description: Where browser automation runs, what starting a browser returns, CDP, live takeover, and billing.

# Browser and computer use

Short answers on browser automation, the computer-use loop, and live takeover.

Inside a sandbox. The browser is part of the sandbox and starts lazily on the first browser request, then survives pause and resume.
See [Browser use](/docs/browser-use/).

A `stream_url` (live view), a `cdp_url` (Chrome DevTools Protocol), a one-hour `stream_auth` token, and a 1280x720 viewport.
Every sandbox image includes Chromium and Node, so any sandbox works.
See [Browser use quickstart](/docs/browser-use/quickstart/).

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SANDBOX_ID/browser \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Connect over CDP to the same browser a human can watch, so cookies and logins are shared.
Detach when you are done rather than calling `browser.close()`.
See [Drive the browser over CDP](/docs/browser-use/cdp/).

Yes. Share a live viewer link for browser sessions, or take over a Computer desktop directly.
The live viewer needs the sandbox's virtual display, which a SOMA sandbox does not have yet.
See [Live viewer](/docs/browser-use/live-viewer/) and [Embed a live desktop](/docs/computers/embedding/).

Screenshot, decide, take one action, screenshot again.
Coordinates are screen pixels with the origin at the top left.
See [Computer use quickstart](/docs/computer-use/quickstart/).

Browser use bills as ordinary sandbox usage.

# Business OS and internal use

Short answers on running your own company on MIOSA and building an internal platform.

Yes. The reference map includes MIOSA BusinessOS, a self-hosted business workspace you run internally rather than launch as a product.
See [Agent company reference map](/docs/guides/agent-company-reference-map/).

Managed connectors attach in-VM tools without shipping you vendor tokens; the sandbox gets a placeholder swapped only for that provider's endpoint.
See [Managed connectors](/docs/guides/managed-connectors/).

Pure reasoning needs no device; files and code use a Sandbox; browser and desktop work use a Computer; private customer resources use a local device; serving traffic uses Docker Host.
See [Choose an agent device](/docs/guides/agent-device-selection/).

Follow the build-your-own-platform checklist: workspace, credentials, runtime profile, primary device, dispatch, stream, export, snapshot, publish, scale.

# Getting started

Short answers on the first steps with MIOSA.

Open a category, or use Expand all and Collapse all above the list.
Every question has its own link - the icon on the right - so you can share an answer directly.

The [Quickstart](/docs/quickstart/) recommends **Track 1: sandbox to deployment** first.
Your first success is a site live at the production URL MIOSA returns, verified end to end.
The full walkthrough is [Build and deploy a Next.js app](/docs/learn/first-production-app/).

With a MIOSA API key in an `Authorization: Bearer` header, or with a JWT from `POST /auth/login`.
See [Authentication](/docs/authentication/) and [API keys](/docs/platform/api-keys/).

Install the `miosa` CLI (v2.2) from npm, Homebrew, the install script, or a release archive.
Then run `miosa login` for the device-code flow and `miosa whoami` to confirm the active organization and workspace.
See [Install the CLI](/docs/cli/install/).

```bash
miosa login     # device-code flow
miosa whoami    # confirm the active organization and workspace
```

Create one under **Workspace → Settings → API Keys**.
The plaintext is shown once and only the hash is stored.
Key families are `msk_u_` (user), `msk_p_` (tenant platform), and `msk_a_` (operator admin, not self-service).
Default rates are 600 requests per minute for a user key and 30,000 for a platform key; rotate every 90 days.
See [API keys](/docs/platform/api-keys/).

No.
There are no dedicated test-mode keys: `msk_u_*` and `msk_p_*` keys hit the billable production substrate.
Use a sandbox or a separate workspace for experiments.

Free-form `metadata`, plus the queryable `external_user_id`, `external_workspace_id`, and `external_project_id`.
See [Metadata and labels](/docs/develop/sandboxes/metadata/).

`us-west` (default), `us-east`, and `us-mia`, all generally available.
A resource lives in one region for its lifetime, so create one per region.
EU and APAC are on the roadmap.
See [Regions](/docs/regions/).

# Pricing and limits

Short answers on what is billable, the sizes and caps, and how credits work.

Running sandboxes and computers at the hourly price of their size, apps and databases on what they use (never more than the price of their size), paused storage, storage and egress, and builds.
The full list is on [Pricing and limits](/docs/pricing/).

```bash
miosa usage my-box           # runtime, time left and estimated cost
```

Storage only. Billing for compute stops when the sandbox leaves `running`.
See [Sizing and limits](/docs/develop/sandboxes/sizing/).

`xs` (1 vCPU, 2 GiB, 10 GiB) through `xl` (16 vCPU, 32 GiB, 80 GiB), with `small` as the default.
See [Sizing and limits](/docs/develop/sandboxes/sizing/).

Concurrent sandboxes per plan (Developer 10, Business 250, Enterprise 500; upgrade or raise it through support), `timeout_sec` 1 to 86400, an 86,400 second maximum exec timeout, a 500 MB maximum upload, and a 1 hour browser token TTL.
See [Pricing and limits](/docs/pricing/).

60 to 30,000 requests per minute per API key by tier, and 2,500/25,000/100,000 per minute per workspace on Developer/Business/Enterprise, with `429` and `Retry-After` on overrun.
See [Rate limits](/docs/rate-limits/).

The [Quotas API](/docs/api-reference/quotas/) sets `max_sandboxes`, `max_concurrent`, `max_storage_gb`, and `max_credit_cents` per `external_user_id`, enforced at create time.

MIOSA bills you once; you charge your customers using attribution.
The [Usage Rollup API](/docs/api-reference/usage-rollup/) groups by `external_user_id`, `external_project_id`, or `workspace_id`.
See [Usage and billing](/docs/platform/usage-and-billing/).

It depends on the grant.
Credits you add do not expire.
Recurring plan credits expire at the start of the UTC day after the 30-day billing period.
Promotional credits (the one-time welcome grant and promo-code redemptions) expire 180 days after they are granted.
The nearest expiry is reported as `credit_expiry_at` on `GET /api/v1/credits/balance`.

# SOMA and runtimes

Source: src/routes/docs/faq/runtimes/+page.md
Description: What SOMA is, the default runtime, how to select one, access requests, and availability.

# SOMA and runtimes

Short answers on the runtime you boot a sandbox on.

SOMA (Secure Optimized Machine Architecture) is MIOSA's own open-source Rust VMM on Linux KVM, giving each sandbox one hardware-isolated VM with its own kernel.
See [SOMA](/docs/soma/).

Pass `runtime_profile: "standard" | "soma" | "auto"` when creating a sandbox, from the REST API, the SDKs (`runtime`), the CLI (`miosa create --runtime`), or the console.
An invalid value returns `INVALID_SANDBOX_RUNTIME_PROFILE`; there is no silent fallback.
`GET /api/v1/sandboxes/runtimes` lists the runtimes your organization can select.
See [Choosing a runtime](/docs/soma/choosing-a-runtime/).

```bash
miosa create --runtime soma --size small
```

Yes. SOMA is available to every customer, at `small`, `medium`, and `large`, with live vCPU and memory resize.
`GET /api/v1/sandboxes/runtimes` reports what each runtime supports today.
See [SOMA](/docs/soma/).

Sandboxes, previews, publishing, data, white-label, SOMA, and the sandbox browser are generally available.
Computers, dynamic deployments, Docker Host, and tenant deployment domains are in partner preview; GPU-backed sandboxes are not productized and remain on the roadmap.
See [Availability and roadmap](/docs/availability/).

# Sandboxes and computers

Source: src/routes/docs/faq/sandboxes-and-computers/+page.md
Description: Sandbox vs Computer, the default sandbox, run length, states, pausing, and snapshots.

# Sandboxes and computers

Use a [Sandbox](/docs/develop/sandboxes/) for code, files, and processes.
Use a [Computer](/docs/computers/overview/) when you need a visible desktop, a browser login, or human takeover.
Use **Docker Host** when you need a durable, always-on URL.

```bash
miosa create my-box --wait     # provision a sandbox and wait until it is ready
miosa list                     # see all your sandboxes
```

A headless microVM that is persistent by default, with `/workspace` as the editable root, booted from a template (usually `miosa-sandbox`).
The default size `small` is 2 vCPU, 4096 MiB RAM, and 10240 MiB disk, and responses carry a versioned `resource_contract`.
See [Sandboxes](/docs/develop/sandboxes/) and [Sizing and limits](/docs/develop/sandboxes/sizing/).

A Computer is a durable cloud Linux desktop (Xfce and Firefox) with screenshot, click, type, and streaming, plus human takeover.
You embed or share it through `computer.urls()["desktop_url"]`.
See [Computers](/docs/computers/overview/) and [Embed a live desktop](/docs/computers/embedding/).

`timeout_sec` is 1 to 86400 seconds, default 3600.
`always_on` disables timeout enforcement subject to tenant policy.
The timeout counts from the last activity, and expiry stops a persistent sandbox and destroys a non-persistent one.
A sandbox also stops after 30 minutes idle by default on accounts created on or after October 11, 2026 (set `idle_timeout_sec` to `0` to disable), and a stopped sandbox wakes on the next request.
See [Timeouts and auto-stop](/docs/develop/sandboxes/timeouts/).

`creating`, `running`, `stopped`, `paused`, `error`, and `destroyed`.
`paused` exists only on a runtime that advertises pause, which is Firecracker today; SOMA has no pause.
See [Sandbox lifecycle](/docs/develop/sandboxes/lifecycle/).

No. Stop keeps the sandbox id and the disk, including files, installed packages, and enabled services; resume brings it back.
Stop never keeps running processes.
Pause (Firecracker only) keeps processes for up to 30 minutes, then behaves like a stop.
Persistent means the sandbox survives a stop, not the loss of its host; the `durability` field says how many hosts hold the saved state.
SOMA does not support persistence, pause, or snapshots yet.
Destroy is what removes saved state.
See [Snapshots and persistence](/docs/develop/snapshots/).

Restore builds a new sandbox from a checkpoint; fork branches a running sandbox into an independent one.
Both leave the source unchanged.
See [Snapshots and persistence](/docs/develop/snapshots/).

```bash
miosa snapshot save my-box before-upgrade   # pin a named restore point
miosa snapshot fork before-upgrade          # branch it into an independent sandbox
```

No. A snapshot captures the sandbox disk and, where the runtime advertises it, memory only.
External databases, object storage, connectors, and third-party services are not rolled back with it.
Keep durable state in a data service.
See [Data overview](/docs/data/overview/).

# Security and compliance

Short answers on certifications, data location, secrets, and retention.

SOC 2 Type I is complete, and the report is available to customers and prospects under NDA.
SOC 2 Type II is in progress, with the observation window underway.
See [Trust](/trust).

MIOSA runs HIPAA-compliant infrastructure for healthcare workloads, and business associate agreements (BAAs) are available for Enterprise customers.
See [Trust](/trust).

In United States data centers we provision, network, and manage directly; MIOSA is not a reseller of a hyperscaler.
The three live regions are all in the US, and a resource cannot move between them after creation.
See [Regions](/docs/regions/) and [Trust](/trust).

Values are encrypted with ChaCha20-Poly1305.
Sandboxes see an opaque `miosa-tok-<hex>` placeholder that is swapped at egress, so no one - including MIOSA engineers - can re-read a stored value.
See [Secrets](/docs/security/secrets/).

Egress audit events are retained 90 days.
Usage and credit records are kept separately.
There is no published zero-retention mode.
See [Data retention](/docs/data-retention/).

No. There are no `pk_*` publishable keys: API keys are server-only.
Browser and embed access uses short-lived scoped tokens instead (`mp_` preview, `ms_` share, and browser tokens).
See [API keys](/docs/platform/api-keys/) and [Browser tokens](/docs/platform/browser-tokens/).

# White-label and platform builders

Short answers on running MIOSA under your own brand for your customers.

Your platform maps to one MIOSA organization, with a workspace per downstream customer and a project per thing they build.
End users never need a MIOSA account.
See [White-label platform architecture](/docs/platform/overview/).

A preview domain (`https://{port}-{slug}.sandbox.{preview_domain}`), a deployment domain (`https://{slug}.{deployment_domain}`), and a MIOSA fallback (`https://{slug}.{organization_slug}.miosa.app`).
See [Branding and domain setup](/docs/platform/white-label/).

Never put an `msk_*` key in a browser.
Your backend mints short-lived scoped tokens, and end-user-scoped secrets and OAuth are keyed on `external_user_id`.
See [Attribution](/docs/platform/attribution/) and [White-label credentials](/docs/security/white-label/).

MIOSA charges the organization owner for all usage in one bill.
Charge back to customers by grouping the Usage Rollup on `workspace_id` or the `external_*` fields.
See [Usage and billing](/docs/platform/usage-and-billing/).

Yes. Set `custom_app_name`, `custom_logo_url`, `support_url`, `desktop_wallpaper_url`, and `powered_by_visible` through `PUT /api/v1/tenant/branding`.

# Forge

URL: https://miosa.ai/docs/forge
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge
Source: src/routes/docs/forge/+page.md
Description: Git hosting built into MIOSA: a home for code written by you, your sandboxes and your agents, with deploys, pull request previews and merge rules.

Forge is Git hosting that is part of MIOSA.
Every organization has it, and every repository lives next to the sandboxes, agents and deployments that use it.

## Why Forge exists

Most code on MIOSA is not typed on a laptop.
It is written inside a sandbox, by you or by an agent such as Optimal, and it needs somewhere to go when the sandbox is done.
Forge is that place.

- **One account.** Your MIOSA API key is your Git credential. There is no separate Git host account and no access token to copy around.
- **Deploy from a branch.** Point a deployment at a branch and every push builds and ships a new version.
- **A preview for every pull request.** Each pull request on a linked repository gets its own preview version and a `deploy` check.
- **Merge rules you can enforce.** Branch policy decides how many approvals and which checks a pull request needs before it can merge.
- **Agents are first-class.** The same repositories are reachable from the CLI, the REST API and the SDKs, under the same permissions.

    Repo -->|pull request| Preview["Preview version + deploy check"]
    Repo -->|push to main| Deploy["Deployment: new version live"]
    Preview -->|policy met, merge| Deploy

## What a repository gives you

| Area | What you get |
|---|---|
| Git | Clone, fetch and push over HTTPS at `https://forge.miosa.ai/<org>/<repo>.git` |
| Pull requests | Open, review, comment, diff, close, reopen and merge |
| Checks | Results reported against a commit, with evidence, that branch policy can require |
| Branch policy | Required approvals, independent reviewers, required checks, code owners |
| Releases | Tags with notes and downloadable assets, including a source archive |

Repositories are private by default.
Access follows your organization's roles, and each repository can grant extra roles to people.

## Where to start

- [Quickstart](/docs/forge/quickstart): a repository, a push and a pull request in five minutes.
- [Pull requests and checks](/docs/forge/pull-requests): reviews, checks, branch policy and merging.
- [From a sandbox](/docs/forge/sandboxes): plain `git push` from inside a sandbox.
- [Agents and the API](/docs/forge/agents): Forge from the SDKs and the REST API.
- [CLI reference](/docs/forge/cli): every `miosa forge` command with an example.
- [Limits and FAQ](/docs/forge/faq): what Forge does not do yet.

Forge uses your MIOSA login: `miosa login` gives the CLI a key that can read and write Forge.
A key you create yourself under **API keys** needs the `forge:read` and `forge:write` permissions.

# Agents and the Forge API

URL: https://miosa.ai/docs/forge/agents
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge/agents
Source: src/routes/docs/forge/agents/+page.md
Description: Use Forge from the TypeScript and Python SDKs and the REST API: repositories, files, branches, pull requests, checks and releases.

Agents reach Forge the same way you do: with a MIOSA API key, under the same organization roles and branch policy.
Nothing an agent does can skip a policy that would stop you.

## From the TypeScript SDK

```bash
npm install @miosa/sdk
```

```ts

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY });

// Every repository in your organization.
const repos = await miosa.forge.repositories.list();
console.log(repos.map((repo) => repo.name));

// Read a file from the default branch.
const repo = repos.find((r) => r.slug === "hello-forge");
const file = await miosa.forge.repositories.blob(repo.id, { path: "public/index.html" });
console.log(file.content);
```

`miosa.forge.repositories` also has `create`, `get`, `refs`, `tree`, `readme`, `commits`, `putFile`, `deleteFile`, `update` and `delete`.
The Python SDK has the same surface as `client.forge`.

## The REST API

All routes are under `https://api.miosa.ai/api/v1/forge/repositories` and take your key as `Authorization: Bearer <key>`.
`:id` is the repository id.

| Method | Path | What it does |
|---|---|---|
| `GET` | `/` | List repositories |
| `POST` | `/` | Create a repository |
| `GET` | `/:id` | Show a repository |
| `GET` | `/:id/refs` | Branches and tags |
| `GET` | `/:id/tree?ref=main&path=` | A directory listing |
| `GET` | `/:id/blob?ref=main&path=README.md` | A file's content |
| `GET` | `/:id/commits?ref=main` | Commit history |
| `POST` | `/:id/branches` | Create a branch: `{"name": "...", "from": "main"}` |
| `PUT` | `/:id/files/:path` | Write a file as a commit on a branch |
| `GET` | `/:id/pull-requests` | List pull requests |
| `POST` | `/:id/pull-requests` | Open a pull request: `{"title", "head", "base"}` |
| `POST` | `/:id/pull-requests/:number/reviews` | Review a pull request |
| `POST` | `/:id/pull-requests/:number/merge` | Merge a pull request |
| `POST` | `/:id/pull-requests/:number/close` | Close a pull request |
| `GET` | `/:id/check-suites` | Checks reported against commits |
| `GET` | `/:id/releases` | List releases |
| `POST` | `/:id/releases` | Publish a release |

Each `POST` and `PUT` needs an `Idempotency-Key` header.
Repeating a request with the same key returns the first result instead of acting twice, so an agent can retry safely.
Without the header the API answers `IDEMPOTENCY_KEY_REQUIRED`.

### Write a file to a branch

A file write is a commit.
It needs the branch's current head commit as `expected_head`, so two writers never overwrite each other silently:

```bash
curl -X PUT "https://api.miosa.ai/api/v1/forge/repositories/$REPO_ID/files/public%2Fapi.html" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d "{\"path\": \"public/api.html\", \"content\": \"<p>From the API.</p>\\n\", \"message\": \"Add a page from the API\", \"branch\": \"api-branch\", \"expected_head\": \"$HEAD_SHA\"}"
```

The answer has the new commit and the policy decision that allowed it.
Without `expected_head` the API answers `EXPECTED_HEAD_REQUIRED`; get the head from `GET /:id/refs`.

# Forge CLI reference

URL: https://miosa.ai/docs/forge/cli
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge/cli
Source: src/routes/docs/forge/cli/+page.md
Description: Every miosa forge command with an example: auth, repositories, pull requests, checks, branch policy, grants, forks and releases.

Every command takes a repository by name, `org/name` or id, except `repo show`, `repo update` and `repo delete`, which take the id.
Add `--json` to any command for a stable JSON envelope.
Commands that change something take `--idempotency-key`, so a retry never acts twice.

These examples use CLI 2.3.10.
Run `miosa update` to get the latest.

## auth

| Command | Example |
|---|---|
| `auth setup-git` | `miosa forge auth setup-git` |

Makes git use your MIOSA key for `https://forge.miosa.ai`.
`--host` points it at another Forge host.

## repo

| Command | Example |
|---|---|
| `repo create` | `miosa forge repo create hello-forge --visibility private --default-branch main` |
| `repo list` | `miosa forge repo list` |
| `repo show` | `miosa forge repo show <repository-id>` |
| `repo clone` | `miosa forge repo clone hello-forge` |
| `repo update` | `miosa forge repo update <repository-id> --name "Hello Forge"` |
| `repo delete` | `miosa forge repo delete <repository-id> --yes` |

`repo create` also takes `--slug` and `--project-id`.
`repo delete` is permanent.

## pr

| Command | Example |
|---|---|
| `pr new` | `miosa forge pr new hello-forge --head greeting --title "Change the greeting"` |
| `pr list` | `miosa forge pr list hello-forge --state all` |
| `pr show` | `miosa forge pr show hello-forge 1` |
| `pr diff` | `miosa forge pr diff hello-forge 1 --name-only` |
| `pr comment` | `miosa forge pr comment hello-forge 1 --body "Looks good to me."` |
| `pr comments` | `miosa forge pr comments hello-forge 1` |
| `pr review` | `miosa forge pr review hello-forge 1 --decision approved --body "Ship it."` |
| `pr merge` | `miosa forge pr merge hello-forge 1` |
| `pr check` | `miosa forge pr check hello-forge 1 --name lint --conclusion passed --head-sha <sha> --file check.json` |
| `pr checkout` | `miosa forge pr checkout hello-forge 2 --branch review-2` |
| `pr close` | `miosa forge pr close hello-forge 2` |
| `pr reopen` | `miosa forge pr reopen hello-forge 2` |

`pr new` takes `--base`, `--body`, `--draft` and `--head-repo` for a pull request from a fork.
`pr list` filters with `--state open|closed|merged|all`, `--author` and `--base`.
`pr review --decision` is `approved`, `changes_requested` or `commented`.
`pr check` reports a check on the pull request's head commit and is refused for the pull request's own author.

## check

| Command | Example |
|---|---|
| `check report` | `miosa forge check report hello-forge --commit <sha> --name unit-tests --conclusion passed --file check.json` |
| `check list` | `miosa forge check list hello-forge --commit <sha>` |
| `check suite` | `miosa forge check suite hello-forge <sha>` |
| `check show` | `miosa forge check show hello-forge <check-id>` |
| `check evidence` | `miosa forge check evidence hello-forge <check-id>` |

A completed check needs `{"evidence": {...}}` in `--file`, up to 64 KB.
`--status queued` or `in_progress` reports a check that is still running.

## policy

| Command | Example |
|---|---|
| `policy show` | `miosa forge policy show hello-forge` |
| `policy set` | `miosa forge policy set hello-forge --approvals 1 --check unit-tests` |
| `policy owners` | `miosa forge policy owners hello-forge` |

See [branch policy](/docs/forge/pull-requests#branch-policy) for every flag.

## grant

| Command | Example |
|---|---|
| `grant set` | `miosa forge grant set hello-forge <user-id> --role write` |

Roles are `read`, `write`, `maintain` and `admin`.

## fork

| Command | Example |
|---|---|
| `fork` | `miosa forge fork hello-forge --name hello-forge-fork` |

## release

| Command | Example |
|---|---|
| `release tag` | `miosa forge release tag hello-forge --name v0.1.0 --message "First tag"` |
| `release new` | `miosa forge release new hello-forge --tag v0.1.0 --name "First release" --body "Hello from Forge."` |
| `release upload` | `miosa forge release upload hello-forge v0.1.0 --source-archive` |
| `release list` | `miosa forge release list hello-forge` |
| `release show` | `miosa forge release show hello-forge v0.1.0` |

`release new` creates the tag if it does not exist; `--commit` picks what it points at and `--prerelease` marks it.
`release upload` attaches files, or a `.tar.gz` of the tagged commit with `--source-archive`.

# Forge limits and FAQ

URL: https://miosa.ai/docs/forge/faq
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge/faq
Source: src/routes/docs/forge/faq/+page.md
Description: What Forge does and does not do yet: visibility, permissions, merge methods, issues, repository secrets and CI.

## Are repositories private?

Yes, by default.
A repository is `private`, `internal` or `public`, set with `repo create --visibility` or changed later with `repo update`.
Members of your organization get access through their organization role, and `grant set` gives one person an extra role on one repository.

## Which permissions does my API key need?

`forge:read` to clone, fetch and read, and `forge:write` to push, open and merge pull requests, report checks and publish releases.
`miosa login` gives a key with both.
A key without them gets `insufficient scope` and the name of the permission it needs.

## Can I use the GitHub CLI or another Git host?

Forge speaks standard Git over HTTPS, so any Git client works once `miosa forge auth setup-git` has run.
Pull requests, checks, policy and releases use `miosa forge`, the API or the SDKs.

## Can I import a repository from GitHub?

Yes, from the console.
An import copies the history once; a GitHub App connection keeps a repository mirrored.

## What Forge does not do

| Not supported | What to do |
|---|---|
| Issues | Track work in your own tool, or in pull request comments |
| Repository secrets | Set them on the deployment with `miosa deploy env-set` |
| CI that runs on push | Run your tests elsewhere and report the result with `miosa forge check report` |
| Squash, rebase and auto merge | Merges create a merge commit; the server refuses the other methods without merging |
| Pushing from a sandbox with its own identity | See [Forge from a sandbox](/docs/forge/sandboxes) |
| Raw file download, blame and Git LFS | Clone the repository |

Forge does not do these today.

## Why was my merge refused?

The pull request does not meet the branch policy yet, and nothing was merged.
The error names what is missing and the command that fixes it; see [Fix "needs approval"](/docs/forge/pull-requests#fix-needs-approval).

# Pull requests and checks

URL: https://miosa.ai/docs/forge/pull-requests
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge/pull-requests
Source: src/routes/docs/forge/pull-requests/+page.md
Description: Open a pull request on Forge, report checks, set branch policy and merge.

A pull request on a Forge repository works the way you expect from other Git hosts.
Checks report results against its commits, and branch policy decides when it can merge.

## Open a pull request

Push a branch, then open the pull request against the default branch:

```bash
git checkout -b greeting
sed -i.bak 's/Hello from Forge/Hello again from Forge/' public/index.html && rm public/index.html.bak
git commit -am "Change the greeting"
git push -u origin greeting
miosa forge pr new hello-forge --head greeting --title "Change the greeting" --body "Says hello again."
```

```text
Number:  1
Title:   Change the greeting
State:   open
From:    greeting
Into:    main
```

Read it back, see what changed and talk about it:

```bash
miosa forge pr list hello-forge
miosa forge pr show hello-forge 1
miosa forge pr diff hello-forge 1 --name-only
miosa forge pr comment hello-forge 1 --body "Looks good to me."
miosa forge pr comments hello-forge 1
```

## Branch policy

Branch policy decides what a pull request needs before it can merge into a branch.

```bash
miosa forge policy show hello-forge
```

```text
Policy:         main v1 (default policy)
Merging needs:  no approval needed (solo organization; the default policy tightens when a second member joins)
Approvals:      1
Independent:    yes
Self-merge:     yes
Checks:         none
```

An organization with one member merges without approvals.
Once a second person joins, the default policy asks for one approval from someone other than the author.

Set your own rules with `policy set`:

```bash
miosa forge policy set hello-forge --approvals 1 --check unit-tests
```

| Flag | What it does |
|---|---|
| `--approvals N` | How many approvals a pull request needs |
| `--independent` | The approver must be someone other than the author (default on) |
| `--check NAME` | A check that must pass; repeat it for several |
| `--code-owners` | Require a code owner's approval |
| `--dismiss-stale` | New commits dismiss earlier approvals (default on) |
| `--branch NAME` | The branch the policy covers (default: the default branch) |

### Working alone

An organization with one member can turn off the approval requirement so the author merges their own pull requests:

```bash
miosa forge policy set hello-forge --branch main --approvals 0 --independent=false
```

Required checks still apply.

## Report your own checks

Any tool can report a check against a commit, for example a test run.
A completed check needs evidence: a JSON file with an `evidence` object of up to 64 KB.

```bash
echo '{"evidence": {"runner": "npm test", "passed": 12, "failed": 0}}' > check.json
miosa forge check report hello-forge --commit "$(git rev-parse HEAD)" --name unit-tests --conclusion passed --summary "12 tests passed" --file check.json
miosa forge check list hello-forge --commit "$(git rev-parse HEAD)"
```

A check that branch policy requires must be reported by someone other than the pull request's author: MIOSA itself, a CI identity or another member of your organization.
That way an author can never pass their own gate.
A check the author reports still shows on the pull request, but it does not count toward the policy, and `miosa forge pr check` refuses it with `CHECK_SEPARATION_REQUIRED`.

## Review and merge

A teammate reviews the pull request; the author cannot approve their own:

```bash
miosa forge pr review hello-forge 1 --decision approved --body "Ship it."
```

When the branch policy is met, anyone with write access merges it:

```bash
miosa forge pr merge hello-forge 1
```

```text
ok  Merged pull request #1 into main as 0d4d9eebbc76
```

Today a merge always creates a merge commit.
The CLI already has `--squash`, `--rebase` and `--auto`, but the server refuses them with `this MIOSA server does not support --squash yet; nothing was merged`.
Nothing is merged when that happens.

## Fix "needs approval"

When a pull request does not meet its branch policy, the merge is refused and nothing changes:

```text
miosa: pull request #3 cannot merge: policy main v5 needs 1 approval from someone other than the author [REQUIRED_APPROVALS_MISSING]
  Ask someone with write access to approve:  miosa forge pr review hello-forge 3 --decision approved
  Working alone? Let the author merge:      miosa forge policy set hello-forge --branch main --approvals 0 --independent=false
```

Either ask a member with write access to approve, or, if you work alone, lower the policy with the second command.
A missing required check fails the same way with `REQUIRED_CHECK_EVIDENCE_UNAVAILABLE`; run `miosa forge pr show` to see which check is missing.

## Work on someone else's pull request

```bash
miosa forge pr checkout hello-forge 2 --branch review-2
miosa forge pr close hello-forge 2
miosa forge pr reopen hello-forge 2
```

# Forge quickstart

URL: https://miosa.ai/docs/forge/quickstart
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge/quickstart
Source: src/routes/docs/forge/quickstart/+page.md
Description: Create a Forge repository, push to it with plain git and open your first pull request, in five minutes.

This takes about five minutes.
You need the `miosa` CLI (version 2.3.10 or later) and `git`.

## 1. Sign in

```bash
miosa login
miosa whoami
```

`miosa login` gives the CLI a key with the Forge permissions, `forge:read` and `forge:write`.
If you use an API key you created yourself instead, tick both permissions when you create it under **API keys** in the console, then `export MIOSA_API_KEY=msk_...`.
Without them every `miosa forge` command answers `insufficient scope`.

## 2. Let git use your MIOSA login

```bash
miosa forge auth setup-git
```

```text
ok  git now uses your MIOSA login for https://forge.miosa.ai
```

This adds a credential helper for `forge.miosa.ai` to your global git config.
Git then signs in with your MIOSA key, so you never paste a password or token.

## 3. Create a repository and clone it

```bash
miosa forge repo create hello-forge
miosa forge repo clone hello-forge
cd hello-forge
```

```text
ok  Created repository "hello-forge" in the current organization
  Visibility: private
  Clone URL:  https://forge.miosa.ai/<org>/hello-forge.git
```

A new repository is private and starts empty, so git warns that you cloned an empty repository.

## 4. Commit and push

```bash
mkdir -p public
printf '<!doctype html>\n<title>Hello from Forge</title>\n<h1>Hello from Forge</h1>\n' > public/index.html
git add .
git commit -m "First page"
git push -u origin main
```

That is plain git: any client, editor or tool that speaks Git over HTTPS works the same way.

## 5. Open a pull request

```bash
git checkout -b greeting
sed -i.bak 's/Hello from Forge/Hello again from Forge/' public/index.html && rm public/index.html.bak
git commit -am "Change the greeting"
git push -u origin greeting
miosa forge pr new hello-forge --head greeting --title "Change the greeting"
miosa forge pr merge hello-forge 1
```

```text
ok  Merged pull request #1 into main as 0d4d9eebbc76
```

An organization with one member can merge its own pull requests.
Once a teammate joins, a pull request needs their approval first; see [branch policy](/docs/forge/pull-requests#branch-policy).

## Clean up

```bash
miosa forge repo list
miosa forge repo delete <repository-id> --yes
```

`repo delete` takes the repository id that `repo list` shows, and it is permanent.

# Forge from a sandbox

URL: https://miosa.ai/docs/forge/sandboxes
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/forge/sandboxes
Source: src/routes/docs/forge/sandboxes/+page.md
Description: Clone and push to Forge from inside a sandbox with plain git, using the sandbox's own identity.

Code written inside a sandbox, by you or by an agent, should land in a Forge repository with a plain `git push`.
No API key is copied into the sandbox for that.

Everything on this page is rolling out now.
Until it reaches your organization, a `git clone` or `git push` to Forge from inside a sandbox answers `Authentication failed`.

## How it works

A sandbox already carries its own token, scoped to its organization and workspace.
Forge accepts that token for the repositories of the sandbox's own workspace, and the sandbox writes a git credential helper for `forge.miosa.ai` when it boots.
So inside the sandbox, git just works:

```bash
git clone https://forge.miosa.ai/<org>/<repo>.git
cd <repo>
git checkout -b from-sandbox
echo "<p>Written in a sandbox.</p>" >> public/index.html
git commit -am "Edit from a sandbox"
git push -u origin from-sandbox
```

The sandbox reaches only the repositories of its own workspace, with the same branch policy as everyone else.
Then open a pull request from your machine, the CLI or the API, as in [pull requests](/docs/forge/pull-requests).

## Today, before it reaches you

Do not copy a personal API key into a sandbox to work around it: anyone and any agent that can read the sandbox can read the key.
If you need the files now, copy them out with `miosa files cp -r my-box:/workspace/site ./site` and push from your machine.

Source: src/routes/docs/fundamentals/+page.md
Description: The mental model every MIOSA integrator needs  -  workspace, authentication, resources, attribution, idempotency, rate limits, errors, and events.

# Fundamental Concepts

MIOSA is a cloud platform for building and deploying applications. Before writing your first API call, read this page. It covers the concepts that underpin every MIOSA integration.

This page is the **API protocol** reference: authentication, tokens, idempotency, rate limits, errors, events, and tenant-level configuration.
For the **resource model** - what the resources are and how they relate - see [Core Concepts](/docs/concepts/).

## What every integration needs

| Topic | Read |
|---|---|
| API keys, browser tokens, and the five token types | [Authentication](/docs/fundamentals/authentication/) |
| Mapping resources to your own customers | [Ownership and external attribution](/docs/fundamentals/attribution/) |
| Safe retries, quotas, and error handling | [Requests, limits, and errors](/docs/fundamentals/requests/) |
| Streaming progress over SSE | [Events (SSE)](/docs/fundamentals/events/) |
| Webhooks and per-end-user quotas | [Tenant configuration](/docs/fundamentals/tenant-config/) |

## Where resources live

This page covers the API protocol. The full **resource model** - the ownership chain, the development and production resources, and how they relate - lives in [Core Concepts](/docs/concepts/).

In short: your account is one **organization** (a permanent slug, one billing account, and API keys). Inside it, **workspaces** separate customers, clients, teams, or environments, and **projects** group the resources for one product. Sandboxes, Computers, Deployments, Databases, Domains, Storage, Volumes, Functions, and Jobs belong to a project. Every request resolves one unambiguous organization, workspace, and project.

## Sandboxes vs Computers

Sandboxes and Computers are two different products with different lifecycles and different use cases. The comparison table and the resource-model context live in [Core Concepts](/docs/concepts/#computers-desktop-product).

- Use a **Sandbox** when the agent needs to write code, run shell commands, manage files, or serve a dev server.
- Use a **Computer** when the agent needs to operate a graphical interface - a browser, a desktop app, or anything with a visible screen.

Both products live in the same organization, can be separated by workspace/project, and appear on the same billing account.

# Ownership and external attribution

URL: https://miosa.ai/docs/fundamentals/attribution
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/fundamentals/attribution
Source: src/routes/docs/fundamentals/attribution/+page.md
Description: Canonical ownership fields, opaque external attribution, and usage rollup for platforms that resell MIOSA to their own customers.

# Ownership and external attribution

Every MIOSA resource accepts canonical ownership fields and optional attribution fields:

| Field | Meaning |
|---|---|
| `workspace_id` / `workspace_slug` | The MIOSA workspace that owns the resource |
| `project_id` / `project_slug` | The MIOSA project that owns the resource |
| `external_workspace_id` | Your customer's account / tenant ID |
| `external_user_id` | The end-user inside that account |
| `external_project_id` | The project or app ID in your own database |

Every resource also accepts a free-form `metadata` object (up to 16 key-value string pairs). Use it to carry application-layer context  -  feature flags, plan tier, region, whatever your billing system needs  -  without bloating your own database with a MIOSA resource join.

Integrators use these fields for four main purposes:

- **Usage rollup**  -  query `GET /api/v1/sandboxes?external_workspace_id=acme-co` to aggregate compute time and costs for a downstream customer.
- **Per-end-user quotas**  -  enforce your own rate limits by counting active sandboxes per `external_user_id` before creating a new one.
- **Audit log filtering**  -  the audit log accepts `external_user_id` and `external_project_id` as filters so you can pull a customer-specific activity trail without exposing other customers' data.
- **Chargeback and billing**  -  `external_workspace_id` is the recommended key for billing rollup when you resell MIOSA compute to downstream customers. See the [Audit Log](/docs/api-reference/audit-log) and [Quotas](/docs/api-reference/quotas) references.

MIOSA stores canonical `workspace_id` and `project_id` on each resource. The external fields are stored as opaque strings. Both appear on list/read responses, and list endpoints accept them as filters:

```python
# Create a sandbox attributed to a specific customer
sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    workspace_slug="acme-co",
    workspace_name="Acme Co",
    project_slug="invoice-bot",
    project_name="Invoice Bot",
    external_workspace_id="acme-co",
    external_user_id="alice@example.net",
    external_project_id="invoice-bot",
    metadata={"plan": "pro", "region": "us-east"},
)

# List only sandboxes for that customer
sandboxes = client.sandboxes.list(
    workspace_id=sandbox.workspace_id,
)
```

```typescript
// Create
const sandbox = await miosa.sandboxes.create({
  templateId: 'miosa-sandbox',
  workspaceSlug: 'acme-co',
  workspaceName: 'Acme Co',
  projectSlug: 'invoice-bot',
  projectName: 'Invoice Bot',
  externalWorkspaceId: 'acme-co',
  externalUserId: 'alice@example.net',
  externalProjectId: 'invoice-bot',
  metadata: { plan: 'pro', region: 'us-east' },
});

// Filter
const sandboxes = await miosa.sandboxes.list({
  workspaceId: sandbox.workspaceId,
});
```

```bash
# Create
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{
    "template_id": "miosa-sandbox",
    "workspace_slug": "acme-co",
    "workspace_name": "Acme Co",
    "project_slug": "invoice-bot",
    "project_name": "Invoice Bot",
    "external_workspace_id": "acme-co",
    "external_user_id": "alice@example.net",
    "external_project_id": "invoice-bot",
    "metadata": { "plan": "pro", "region": "us-east" }
  }'

# Filter
curl "https://api.miosa.ai/api/v1/sandboxes?workspace_id=550e8400-e29b-41d4-a716-446655440000" \
  -H "Authorization: Bearer msk_u_..."
```

Filtering is always scoped to your MIOSA organization. You cannot see another organization's resources regardless of what workspace, project, or external IDs you pass.

See [Ownership and Attribution](/docs/platform/attribution/) for the full filter spec and billing split by workspace/project.

# Authentication

URL: https://miosa.ai/docs/fundamentals/authentication
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/fundamentals/authentication
Source: src/routes/docs/fundamentals/authentication/+page.md
Description: API keys, browser tokens, and the five MIOSA token types with their prefixes, callers, and trust levels.

# Authentication

Every API request carries one header:
```http
Authorization: Bearer <token>
```

The token is either an **API key** or a **browser token** (scoped JWT).

## API keys

API keys have the prefix `msk_` followed by a role segment:

| Prefix | Role | Use |
|---|---|---|
| `msk_u_...` | user | General-purpose server-side calls |
| `msk_a_...` | admin | Operator/platform tooling |
| `msk_p_...` | platform | Tenant-wide automation |

**API keys are server-side only.** Never put an `msk_*` key in browser code, a mobile app, or a public repository.

A leaked `msk_*` key grants full workspace access. Revoke it immediately at `DELETE /api/v1/api-keys/{id}` and rotate.

## Browser tokens

For browser-side access  -  embedding a preview, opening a terminal in an iframe  -  your backend mints a short-lived scoped token and passes it to the client:

```python

client = miosa.Miosa(api_key="msk_u_...")

token = client.browser_tokens.create(
    scope="sandbox",
    resource_id="sbx_abc123",
    expires_in=3600,
)
# Pass token.value to the browser  -  never the msk_ key.
```

```typescript

const miosa = new Miosa({ apiKey: 'msk_u_...' });

const token = await miosa.browserTokens.create({
  scope: 'sandbox',
  resourceId: 'sbx_abc123',
  expiresIn: 3600,
});
// Pass token.value to the browser  -  never the msk_ key.
```

```bash
curl -X POST https://api.miosa.ai/api/v1/browser-tokens \
  -H "Authorization: Bearer msk_u_..." \
  -H "Content-Type: application/json" \
  -d '{
    "scope": "sandbox",
    "resource_id": "sbx_abc123",
    "expires_in": 3600
  }'
```

Browser tokens expire, are non-renewable, and are scoped to a single resource. They cannot create new resources.

See [Authentication](/docs/authentication/) and [Browser Tokens](/docs/platform/browser-tokens/) for the full reference.

## Token types

MIOSA issues five distinct token types. Each covers a different caller and trust level:

| Token | Prefix | Caller | TTL | Read / Write |
|---|---|---|---|---|
| API key | `msk_*` | Your server | Until revoked | Read + Write |
| JWT | `ey...` | Admin UI / browser session | ~1 h (refresh 7 d) | Read + Write |
| Browser token | (opaque) | Your user's browser | Configurable (default 1 h) | Read-only, single resource |
| Preview token | `mp_*` | Browser / `` iframe | Configurable (default 1 h) | Read-only, sandbox preview |
| Share token | `ms_*` | Anyone  -  no account required | Configurable | Read-only, sandbox preview |

The `msk_*` API key is the root credential. All other token types are minted downstream from it by your server. Never give an `msk_*` key to a browser or end user.

For minting flows, revocation, and validation rules see [Authentication](/docs/authentication/) and [Preview Tokens](/docs/develop/previews).

# Events (SSE)

URL: https://miosa.ai/docs/fundamentals/events
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/fundamentals/events
Source: src/routes/docs/fundamentals/events/+page.md
Description: Stream progress over Server-Sent Events using one-time tickets - per-resource streams, the tenant-wide stream, and the event catalog.

# Events (SSE)

Several long-running operations stream progress over [Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events). The SSE stream for a resource is always at:
```

GET /api/v1/{resource-type}/{id}/events
```

Because the browser `EventSource` API does not support custom headers, SSE endpoints use a **one-time ticket** for authentication instead of the `Authorization` header:

```python
# 1. Mint a ticket (server-side)
ticket = client.sandboxes.sse_ticket(sandbox_id="sbx_abc123")

# 2. Open the stream

url = f"https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/events?ticket={ticket.value}"
with urllib.request.urlopen(url) as resp:
    for event in sseclient.SSEClient(resp):
        print(event.data)
```

```typescript
// 1. Mint a ticket (server-side)
const ticket = await miosa.sandboxes.sseTicket('sbx_abc123');

// 2. Open the stream (browser or Node)
const url = `https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/events?ticket=${ticket.value}`;
const source = new EventSource(url);
source.onmessage = (e) => console.log(JSON.parse(e.data));
```

```bash
# 1. Mint a ticket
TICKET=$(curl -s -X POST \
  https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/sse-ticket \
  -H "Authorization: Bearer msk_u_..." | jq -r '.ticket')

# 2. Stream events
curl -N "https://api.miosa.ai/api/v1/sandboxes/sbx_abc123/events?ticket=$TICKET"
```

Event types vary by resource. Common event shapes:
```jsonc
// Build log line
{ "type": "log", "stream": "stdout", "data": "Installing dependencies...", "ts": 1748390460 }

// Status change
{ "type": "status_changed", "previous": "building", "current": "ready", "ts": 1748390462 }

// Error
{ "type": "error", "code": "BUILD_FAILED", "message": "Exit code 1", "ts": 1748390465 }
```

## Sandbox lifecycle events

| Event | When |
|---|---|
| `sandbox.created` | Sandbox resource created (not yet booted) |
| `sandbox.ready` | Boot complete, exec and file endpoints available |
| `sandbox.error` | Fatal boot or runtime error |
| `sandbox.destroyed` | Sandbox stopped and resources released |
| `sandbox.share.created` | A share token was minted for the sandbox |
| `sandbox.share.revoked` | A share token was revoked |

## Deployment lifecycle events

| Event | When |
|---|---|
| `deployment.created` | Deployment object created |
| `deployment.build_started` | Builder VM booted, build in progress |
| `deployment.build_succeeded` | Release artifact ready |
| `deployment.build_failed` | Build exited non-zero |
| `deployment.published` | Active version updated, traffic cut over |
| `deployment.rollback` | Active version reset to a prior version |

## Tenant-wide SSE stream

To receive all lifecycle events for your organization without polling per-resource endpoints, subscribe to the tenant stream:

```bash
# Mint a ticket
TICKET=$(curl -s -X POST https://api.miosa.ai/api/v1/events/ticket \
  -H "Authorization: Bearer msk_u_..." | jq -r '.ticket')

# Stream all org events
curl -N "https://api.miosa.ai/api/v1/events?ticket=$TICKET"
```

Each event on the tenant stream includes a `resource_type` and `resource_id` field so you can route to the right handler:
```jsonc
{
  "type": "sandbox.ready",
  "resource_type": "sandbox",
  "resource_id": "sbx_abc123",
  "external_user_id": "alice@example.net",
  "ts": 1748390462
}
```

See [Events (SSE) API Reference](/docs/api-reference/events/) and [Tenant Events](/docs/api-reference/tenant-events) for the complete event catalog and filtering options.

# Requests, limits, and errors

URL: https://miosa.ai/docs/fundamentals/requests
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/fundamentals/requests
Source: src/routes/docs/fundamentals/requests/+page.md
Description: Idempotency keys, rate limits and quota headers, and the MIOSA error envelope with its HTTP status codes.

# Requests, limits, and errors

## Idempotency

Every mutation endpoint (`POST`, `PUT`, `PATCH`, `DELETE`) accepts an optional `Idempotency-Key` header. Retrying a request with the same key is safe  -  MIOSA returns the original response without re-executing the operation.
```http
POST /api/v1/sandboxes
Authorization: Bearer msk_u_...
Idempotency-Key: create-sandbox-for-alice-2026-05-17
Content-Type: application/json

{ "template_id": "miosa-sandbox", "external_user_id": "alice" }
```

Idempotency keys are:

- Scoped to your workspace and the endpoint path.
- Valid for **24 hours** from first use.
- Stored regardless of whether the original request succeeded or failed.

If the first request timed out before you received a response, retry with the same key. You will receive the original result if the operation completed, or a `202 Accepted` if it is still in progress.

Use a deterministic, collision-resistant key tied to your own business event  -  for example, `"create-sandbox-{your_request_id}"`. UUIDs or hash of the request body both work.

## Rate limits

Rate limits apply per API key, per workspace, and per endpoint family. Every response includes quota headers:
```http
X-RateLimit-Limit: 600
X-RateLimit-Remaining: 587
X-RateLimit-Reset: 1748390460
```

Current self-service defaults:

| Credential or endpoint family | Limit | Window |
|---|---|---|
| User API key | 600 requests | Per minute per key |
| Platform API key | 30,000 requests | Per minute per key |
| Auth (`/auth/login`, `/auth/refresh`) | 60 requests | Per minute per IP |

Tenant and endpoint-family policies can impose lower limits.
Treat the response headers as authoritative.

When you exceed a limit, the API returns `429 Too Many Requests` with a `Retry-After` header containing the number of seconds until your quota resets.

High-volume workloads (AI agent pipelines creating many sandboxes per minute) can request a quota increase from the [platform dashboard](https://miosa.ai/dashboard/workspace/quota) or by contacting support.

## Errors

All errors use a consistent envelope:
```json
{
  "error": {
    "code": "SANDBOX_NOT_FOUND",
    "message": "No sandbox with id sbx_abc123 exists in this workspace.",
    "request_id": "req_01hx9z..."
  }
}
```

| Field | Description |
|---|---|
| `code` | Machine-readable constant. Use this in your `switch` statements, not `message`. |
| `message` | Human-readable explanation. May change between API versions. |
| `request_id` | Include this when contacting support or filing a bug report. |

HTTP status codes map directly to error categories:

| Status | Category |
|---|---|
| `400` | Invalid request body or parameters |
| `401` | Missing or invalid credential |
| `403` | Valid credential, insufficient permissions |
| `404` | Resource not found (or not visible to your workspace) |
| `409` | Conflict  -  resource already exists, duplicate idempotency key with different body |
| `422` | Validation error  -  request parsed correctly but failed domain rules |
| `429` | Rate limited |
| `5xx` | MIOSA-side fault  -  safe to retry with exponential backoff |

The full error code catalog is in the [API Reference](/docs/api-reference/).

Description: Tenant-level API surfaces for white-label integrators - webhook subscriptions and per-end-user quotas.

# Tenant configuration

White-label integrators configure tenant behavior through the API surfaces below. All routes accept `msk_a_*` admin keys or admin JWTs.

Preview domains and branding are part of the product model, not this integrator guide: [Core Concepts](/docs/concepts/#tenant-preview-domain) explains what they are and when to use them, and the [Tenant Preview Domain](/docs/api-reference/tenant-preview-domain) and [Tenant Branding](/docs/api-reference/tenant-branding) references give the request schemas.

## Webhooks

Subscribe to sandbox and deployment lifecycle events delivered as HTTPS POST requests to your endpoint. MIOSA signs each request with an HMAC-SHA256 signature in the `X-Miosa-Signature` header:

```bash
POST /api/v1/tenant/webhooks
{ "url": "https://yourapp.com/webhooks/miosa", "events": ["sandbox.*", "deployment.*"] }
```

See [Webhooks](/docs/api-reference/webhooks) and [Integrations](/docs/integrations) for the event catalog and signature verification.

## Per-end-user quotas

Set maximum resource counts per `external_user_id` to prevent runaway usage by a single downstream user. Quotas are checked at resource creation time and return `429` with code `QUOTA_EXCEEDED` when reached:

```bash
PUT /api/v1/tenant/quotas
{ "max_sandboxes_per_user": 5, "max_computers_per_user": 2 }
```

See [Quotas](/docs/api-reference/quotas).

  Your Agent->>MIOSA API: previews.create(port=3000)
  MIOSA API-->>Your Agent: { url }

Your agent code owns the loop: choosing the LLM, formatting tool calls,
interpreting results, and deciding when to stop. MIOSA executes the actions your
agent requests and streams back results.

---

## Sandbox integration

Sandboxes are the preferred substrate for code-generation agents. The agent
writes files, runs build commands, and opens preview URLs through MIOSA
primitives.

```python

client = miosa.Miosa(api_key="msk_u_...")

# Boot a sandbox with a Next.js environment
sbx = client.sandboxes.create("nextjs")

# Agent writes the code it generated
sbx.files.write("/workspace/app/page.tsx", agent_generated_code)

# Run the build
result = sbx.exec("npm run build")
if result.exit_code != 0:
    # Feed stderr back to the agent so it can debug
    agent.feedback(result.stderr)
else:
    # Open a live preview
    preview = sbx.previews.create(port=3000)
    print(f"Preview: {preview.url}")
```

```typescript

const client = new Miosa({ apiKey: 'msk_u_...' });

// Boot a sandbox
const sbx = await client.sandboxes.create({ templateId: 'nextjs' });

// Agent writes the generated file
await sbx.files.write('/workspace/app/page.tsx', agentGeneratedCode);

// Run the build
const result = await sbx.exec('npm run build');
if (result.exitCode !== 0) {
  agent.feedback(result.stderr);
} else {
  const preview = await sbx.previews.create(3000);
  console.log('Preview:', preview.url);
}
```

The sandbox persists between turns. Files written in turn 1 are still there in
turn 5, so the agent does not need to re-send context on every call.

---

## Computer integration

Computers are full Linux desktop VMs with screenshot, click, type, and keyboard APIs. Use them when your agent needs to operate a graphical interface.

```python

client = miosa.Miosa(api_key="msk_u_...")

computer = client.computers.create(template_type="ubuntu-desktop")
computer.start()

# Screenshot → reason → act loop (your agent drives this)
while not done:
    png = computer.screenshot()
    action = agent.next_action(png)

    if action.type == "click":
        computer.left_click(action.x, action.y)
    elif action.type == "type":
        computer.type(action.text)
    elif action.type == "key":
        computer.key(action.combo)  # e.g. "ctrl+t", "enter"
    elif action.type == "scroll":
        computer.scroll(action.direction, x=action.x, y=action.y)
    elif action.type == "done":
        done = True

computer.stop()
```

```typescript

const client = new Miosa({ apiKey: 'msk_u_...' });

const computer = await client.computers.create({ template_type: 'ubuntu-desktop' });
await computer.start();

let done = false;
while (!done) {
  const png = await computer.screenshot();
  const action = await agent.nextAction(png);

  switch (action.type) {
    case 'click':
      await computer.leftClick(action.x, action.y);
      break;
    case 'type':
      await computer.typeText(action.text);
      break;
    case 'key':
      await computer.key(action.combo);
      break;
    case 'done':
      done = true;
      break;
  }
}

await computer.stop();
```

---

## State tracking

Your agent code is responsible for keeping turn history, screenshots, and
decisions. MIOSA executes discrete actions; it does not maintain an agent loop
or conversation state on your behalf.

A managed agent loop with built-in turn history and LLM orchestration is on the MIOSA roadmap. Today, state management lives in your application layer.

A minimal turn-log pattern:

```python
turns = []

while not done:
    png = computer.screenshot()
    action = agent.next_action(png, history=turns)
    turns.append({"screenshot": png, "action": action})

    # Execute action on the computer...
```

---

## Approval workflows

If your workflow requires human review before an action executes, your agent
pauses and asks the user. MIOSA does not gate actions; all approval logic lives
in your application.

```python
action = agent.next_action(png)

if action.requires_approval:
    approved = ask_user(f"Approve: {action.description}?")
    if not approved:
        agent.cancel(action)
        continue

computer.left_click(action.x, action.y)
```

---

## Streaming events

Subscribe to the sandbox or computer event stream to receive real-time progress without polling:

```python
# Sandbox events
for event in sbx.events.stream():
    if event.type == "sandbox.exec.stdout":
        print(event.data["line"])
    elif event.type == "sandbox.exec.completed":
        print(f"Exit code: {event.data['exit_code']}")
        break

# Computer events
for event in computer.events.stream():
    if event.type == "computer.stopped":
        print("Computer stopped:", event.data["reason"])
        break
```

```typescript
// Sandbox events
for await (const event of sbx.events.stream()) {
  if (event.type === 'sandbox.exec.stdout') {
    process.stdout.write(event.data.line);
  } else if (event.type === 'sandbox.exec.completed') {
    console.log('Exit code:', event.data.exit_code);
    break;
  }
}
```

See [Events (SSE) reference →](/docs/api-reference/events/) for the full event catalog.

---

## Best practices

- **Run the agent against a MIOSA device.** For code and artifact tasks, write
  files directly into `/workspace` and run commands inside the sandbox. Use the
  local machine for orchestration, not as the place where the final app is built.
- **Use `Idempotency-Key` on every action.** If your agent retries a failed request, the idempotency key prevents duplicate execution. Generate a key tied to your turn ID: `"turn-{turn_number}-{action_type}"`.
- **Cap `max_turns` in your agent loop.** A runaway agent loop can exhaust credits. Set a hard ceiling and surface the failure cleanly to the user.
- **Record screenshots and decisions.** Persist each turn's screenshot and the action taken. When an agent makes a bad decision, this record lets you replay and diagnose without re-running the whole task.
- **Fork at stable checkpoints.** Keep the original running sandbox as the known-good source and use `POST /sandboxes/{id}/fork` for risky work in an independent branch.
- **Prefer sandbox exec over computer desktop for code tasks.** File I/O and shell commands through the sandbox API are more reliable and faster than typing into a terminal window on a desktop.

# What MIOSA agents can do

URL: https://miosa.ai/docs/guides/agent-capabilities
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-capabilities
Source: src/routes/docs/guides/agent-capabilities/+page.md
Description: Built-in tools, connected app actions, device execution, artifacts, browser work, and the permission model for agents running on MIOSA.

# What MIOSA agents can do

MIOSA agents are workers that can use real cloud execution. They can research,
write code, run commands, edit files, control a browser or desktop, call
connected apps, create artifacts, start previews, and publish finished apps.

These are the primitives behind products such as Polsia-style autonomous
company operators, Cofounder / Co-Founder AI-style business agents, and
Nebula-style shared virtual devices.

The core rule is simple: the agent should do the work inside a MIOSA device,
not only on the user's laptop and then upload the result later.

```text
User request
  -> agent plans
  -> MIOSA device executes
  -> events stream back to the UI
  -> files, previews, artifacts, screenshots, or deployments are saved
```

---

## Built-in toolkits

| Toolkit | What it does | Primary runtime |
|---|---|---|
| Web research | Search, retrieve pages, summarize sources, gather current context | Agent loop or sandbox |
| Filesystem | Read, write, rename, delete, list, and generate files in `/workspace` | Sandbox or computer |
| Code execution | Run Bash, Python, Node, package managers, tests, builds, linters | Sandbox |
| Live server | Start a dev server and expose a preview URL for review | Sandbox |
| Browser | Navigate pages, click, fill forms, extract data, log in to dashboards | Computer or browser-capable sandbox |
| Desktop | Screenshot, click, type, scroll, clipboard, windows, shell | Computer |
| Media and artifacts | Generate PDFs, DOCX, images, diagrams, charts, HTML reports, ZIPs | Sandbox |
| Deployment | Publish a verified workspace to MIOSA Deploy or Docker Host | Deployment pipeline |
| App actions | GitHub, Slack, Google, Refero, or tenant-provided tools | Managed connectors |
| Sub-agent delegation | Split tasks across child sandboxes, computers, or local workers | Orchestrator |

For generated apps, start in a sandbox. Let the agent write files into
`/workspace`, run `npm install`, start the dev server, show the preview, fix
errors in place, snapshot, and then publish.

---

## Tools in action

### Web research

An agent can gather current market examples, inspect docs, compare product
flows, and save notes into the workspace before writing code.

```text
research/
  onboarding-patterns.md
  pricing-pages.md
  competitor-notes.md
```

### Code execution on a workspace device

The agent writes code and runs it inside the sandbox.

```bash
miosa exec <sandbox-id> --cwd /workspace -- npm run test
miosa exec <sandbox-id> --cwd /workspace -- npm run build
```

The UI should stream stdout, stderr, exit status, and file events while the
command runs.

### Browser automation

Use a computer when the agent needs a real browser session:

- open a preview
- log in to a dashboard
- fill forms
- click buttons
- capture screenshots
- verify responsive layouts
- extract data from pages that need a browser

### Artifact generation

Use a sandbox when the agent needs to produce downloadable work:

- proposals
- DOCX/PDF files
- pitch decks
- CSV exports
- charts
- SVG/PNG diagrams
- ZIP bundles
- HTML previews

Generated files should be saved as MIOSA artifacts so the product UI can show
them in an artifacts panel with version history.

### App actions

Connected apps become tools. For example:

- GitHub issues and pull requests
- Slack messages
- Google Drive files
- Gmail drafts
- Refero design research
- tenant-provided APIs

App actions should use managed connectors or scoped tenant credentials, not
secrets pasted into chat.

### Sub-agent delegation

One orchestrator can delegate work to multiple runtime workers:

Diagram:
flowchart LR
  O[Orchestrator agent] --> C[Coder sandbox]
  O --> T[Test sandbox]
  O --> B[Browser computer]
  O --> A[Artifact sandbox]
  C --> R[Run events and files]
  T --> R
  B --> R
  A --> R

Use this for large jobs, QA sweeps, parallel tests, research clusters, and
agent-company products.

---

## Device execution

Agents run against a device. MIOSA has three device classes:

| Device | Use it when | Preserves state |
|---|---|---|
| Sandbox Worker | Code, files, commands, previews, artifacts, publish prep | Yes, through pause/resume and snapshots |
| Computer | Browser/desktop automation, screenshots, visual QA, manual handoff | Yes, through persistent computer storage |
| Local Device | User-owned network/files/apps are required | On the user's machine |

Docker Host is not an agent device. It is the durable hosting target after a
sandbox-built app is ready.

See [Agent devices](/docs/guides/agent-devices/) for the full model.

---

## Permissions

Permissions decide what an agent is allowed to do.

| Permission surface | Controls |
|---|---|
| Visibility | Private agent, workspace agent, or platform-managed agent |
| Device access | Which sandboxes, computers, local devices, or pools the agent can use |
| Tool access | Files, exec, browser, deployments, connectors, artifacts |
| Connected accounts | OAuth grants, API keys, managed connectors, tenant-provided integrations |
| Secret exposure | Which environment variables are injected into the runtime |
| Approval policy | Which actions require a human confirmation |
| Quotas | Max child sandboxes, computers, runtime minutes, spend, or concurrency |

Credential rule:

- tenant admin keys stay server-side
- browser code never receives `msk_*` keys
- sandboxes receive scoped runtime tokens
- managed provider tokens stay encrypted in MIOSA
- egress swaps brokered placeholders only for the provider endpoint they belong to

---

## Product surfaces to expose

If you are building an agent platform on MIOSA, show users these things:

- the current plan or task graph
- tool calls as they happen
- command output
- files created or edited
- artifacts with download buttons
- browser screenshots and preview URLs
- connected accounts and missing credentials
- approval prompts for risky actions
- snapshots, forks, and version history
- deployment status and public URL
- usage, credits, and runtime cost

This is the product layer on top of the primitives. The user should understand
that an agent is working in a real device and producing durable outputs.

# Agent CLI workflow

URL: https://miosa.ai/docs/guides/agent-cli-workflow
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-cli-workflow
Source: src/routes/docs/guides/agent-cli-workflow/+page.md
Description: The full CLI release workflow for agents: discovery, scope, sandbox development, preview, publish, promote, recovery, and rollback.

# Agent CLI workflow

Use this page when an AI agent, coding assistant, CI worker, or operator needs the full build-and-release path through MIOSA.
The CLI is the authoritative happy path. Prefer its `--json` output over reconstructing lower-level API calls.

## Start with discovery

```bash
miosa catalog --json
miosa deploy list --json
miosa deploy get <deployment> --json
```

`catalog` reports the canonical compute products, templates, sizes, and readiness the platform offers right now.

`deploy list` and `deploy get` return the deployments you already own, with their status, active release and public URL.

Do not guess a resource id from an old transcript when these commands can return the current inventory.

## Resolve scope before mutation

Every mutation must resolve one unambiguous organization, workspace, application, and environment.

Do not create a replacement sandbox, deployment, database, or Docker Host host just because an identifier was not resolved.

Inspect the intended resource first.

```bash
miosa deploy get <deployment> --json
miosa deploy releases <deployment> --json
```

`deploy get` shows the deployment's identity, environment, active release and route.

`deploy releases` lists the immutable releases already published to it.

Do not commit credentials or secrets to a repository.

Secrets belong in encrypted MIOSA environment storage, not in the manifest or shell history.

## Develop in a persistent sandbox

Use the sandbox development flow for mutable work.

```bash
miosa create my-dev-box --template nextjs --wait
miosa console my-dev-box --cwd /workspace
miosa doctor
```

`create` provisions the sandbox and, with `--wait`, blocks until it is ready for commands.

`console` opens an interactive shell on the sandbox and resumes the same machine on a later run.

`doctor` checks configuration, connectivity and authentication, and reports what it finds.

Dependency installation must use a lockfile-strict command such as `npm ci`.

## Preview before production

```bash
miosa preview create my-dev-box 3000 --name candidate
miosa preview status my-dev-box <preview-id>
```

`preview create` publishes a port on the sandbox at a public URL and prints the URL.

`preview status` reports whether it is serving.

Preview never promotes production.

Read the returned `url` and `status` from the JSON response.

Use the returned URL.

Do not construct a sandbox, deployment, or custom-domain hostname.

## Publish the candidate

```bash
miosa deploy create my-app --from-sandbox my-dev-box --port 3000 --wait --json
```

`deploy create` publishes a sandbox, a git repository or a local directory as a new deployment and, with `--wait`, blocks until it is live and prints its URL.

Each publish produces an immutable release that can be promoted or rolled back to.

A candidate is not production merely because its build succeeded.

## Promote the exact release

```bash
miosa deploy releases <deployment>
miosa deploy promote <deployment> <release>
```

Promotion targets one exact immutable release.

It must not select "latest" by timestamp or rely on a mutable version label.

The production URL stays stable while the active immutable release changes.

If the candidate fails to build, the currently active release remains live.

## Recover an interrupted publish

An HTTP timeout does not prove the backend operation failed.

Re-read the deployment before retrying, and only republish when the previous attempt is proven terminal.

```bash
miosa deploy get <deployment> --json
miosa deploy builds <deployment>
```

Do not start a duplicate publish or promotion while an earlier operation may still be active.

## Roll back deliberately

```bash
miosa deploy rollback <deployment> --to <release-id> --yes --json
```

Rollback also targets one exact immutable release.

Use a known-good release and verify the same route, artifact, data, and configuration contract after activation.

Database migrations must remain backward compatible when an older application release may run against newer data.

## App-builder architecture

Genspark, Emergent, Blackbox AI, Lovable, Replit Agent, Bolt, and v0-style products are not just code
generators. The durable product shape is an agent runtime wrapped around a
persistent build workspace, a visible event stream, a file/artifact panel, a
preview surface, and a publish path.

| App-builder surface | MIOSA primitive |
|---|---|
| Project workspace | Persistent sandbox, snapshots, files, exec |
| File tree and editor | Filesystem API and streamed file events |
| Command log | Streaming exec events |
| Preview pane | Sandbox preview URL |
| Visual QA | Computer with browser, screenshots, and click/type actions |
| Version history | Snapshots, artifacts, git integration in your product |
| Publish button | MIOSA Deploy or Docker Host |
| Public app URL | Deployment `public_url` or workspace domain |
| Usage meter | Credits for model, sandbox runtime, computer runtime, storage, deployment |

The key rule is that code should be created and modified inside the MIOSA
sandbox when the product is an agent-builder. The user's laptop or your backend
can orchestrate, but the actual files, installs, tests, preview server, and
artifact outputs should live in the assigned workspace.

### App-builder implementation checklist

1. Create or resume a persistent sandbox for each app project.
2. Store the sandbox id on your app/project record.
3. Stream agent reasoning summaries, tool calls, file writes, command output,
   preview readiness, and deployment state.
4. Show a file/artifact panel next to chat.
5. Show a live preview frame using the returned preview URL.
6. Use snapshots before risky rewrites and after working milestones.
7. Add a browser computer only when the agent must visually inspect, log into a
   site, fill forms, or do human-style QA.
8. Publish from `/workspace` to MIOSA Deploy or Docker Host.
9. Store the deployment id and version id on the app/project record.
10. Charge credits for model work, sandbox runtime, computer runtime, storage,
    and deploy/runtime usage.

## Cofounder-style company OS on MIOSA

Cofounder describes the product around a company workspace, departments,
agents, tasks, roadmap, shared library, skills, integrations, managed services,
publishing, and settings. The MIOSA implementation uses your backend as the
company control plane and MIOSA as the execution substrate.

```text
Company workspace
  -> roadmap and tasks
  -> departments
  -> agent roster
  -> shared library/context
  -> connected tools and secrets
  -> assigned MIOSA devices
  -> artifacts, previews, deployments, receipts
```

Recommended mapping:

| Cofounder-style concept | MIOSA implementation |
|---|---|
| Company workspace | Your workspace record plus persistent sandbox/computer ids |
| Departments | Agent groups with scopes, tools, budgets, and approval policy |
| Tasks | Agent runs or sessions with event streams and artifacts |
| Roadmap | Product-owned task graph; selected tasks dispatch to MIOSA |
| Library | Files/artifacts in sandbox plus your product database |
| Skills | Agent instructions, skill folders, MCP tools, reusable runbooks |
| Managed services | MIOSA Deploy, Docker Host, data services, connector grants |
| Publishing | Sandbox publish to deployment or Docker Host |
| Settings | Models, domains, inboxes, secrets, budgets, device policy |

---

## MIOSA BusinessOS reference

[BusinessOS](https://github.com/Miosa-osa/BusinessOS) is the MIOSA-owned open
reference for this product category. It is a self-hosted business workspace
template that gives agents an actual operating environment instead of only a
chat thread.

Use BusinessOS as the concrete example when explaining how MIOSA can power a
customer's own business OS, agency OS, content OS, or custom operator product.

| BusinessOS concept | Product lesson | MIOSA platform mapping |
|---|---|---|
| Desktop environment | Agents and humans need a shared place to work | MIOSA Computer or product UI wrapping a sandbox/computer |
| Terminal with OSA | Prompt goes into an agent that can take actions | Agent runtime connected to MIOSA CLI/API/MCP |
| Projects and tasks | Work needs status, owner, deadline, and history | Your task model plus MIOSA run ids and event streams |
| Clients / CRM | Agents need business data, not isolated prompts | Your application database plus managed connectors |
| Documents and contexts | Agent memory should be structured and searchable | Files, artifacts, vectors, docs, and context injection |
| Calendar | Agents need schedule and reminders | Connector grants, scheduled jobs, approvals |
| Module system | The workspace grows by adding tools | Custom product modules backed by sandboxes, computers, and APIs |
| OSA orchestration | One prompt can route to multiple specialist agents | MIOSA agent orchestration, child sandboxes, child computers, receipts |

Recommended BusinessOS-style runtime layout inside a MIOSA sandbox:

```text
/workspace
  /agents
    founder.md
    engineering.md
    sales.md
    support.md
  /context
    company.md
    customers.md
    policies.md
  /modules
    crm/
    docs/
    tasks/
    reports/
  /artifacts
    proposals/
    screenshots/
    exports/
  /runbooks
    launch.md
    support-triage.md
    weekly-review.md
```

BusinessOS is also the bridge between the two major product shapes:

- for an app-builder product, BusinessOS can be the generated app or template
  the agent modifies and deploys;
- for an agent-company product, BusinessOS can be the persistent operating

## Founder guide implementation map

The Cofounder guide is organized around four operating loops: start, build,
sell, and scale. In a MIOSA product, each loop becomes a set of agents, devices,
artifacts, and approvals.

### Start loop

Purpose: turn a vague idea into a specific problem, market, wedge, name, and
next step.

| Work | Agent | Device |
|---|---|---|
| Problem statement | Strategy agent | No device |
| Market/wedge research | Research agent | Sandbox if crawling or artifact generation is needed |
| Customer interview plan | Research or founder agent | No device or sandbox |
| Name/domain/social handle checks | Brand agent | Computer if browser login/inspection is needed |
| First public commitment | Website or artifact agent | Sandbox |

Outputs:

- problem brief
- wedge market definition
- customer interview list
- name/domain shortlist
- first-week plan
- landing-page draft

### Build loop

Purpose: move from idea to working product, repo, deployment, auth, database,
frontend, tests, and production operations.

| Work | Agent | Device |
|---|---|---|
| MVP spec | Product agent | No device or sandbox for artifact |
| Repo scaffold | Engineering agent | Sandbox |
| Deploy setup | Engineering/deploy agent | Sandbox plus deployment |
| Secrets/env docs | Security agent | Sandbox, never raw secrets in chat |
| Auth/database | Engineering agent | Sandbox plus data service |
| Frontend loop | Design/engineering agent | Sandbox plus computer for visual QA |
| Tests and lint | QA agent | Sandbox |
| Production debugging | Ops agent | Sandbox/computer depending on issue |

Outputs:

- product spec
- repo/files in `/workspace`
- preview URL
- test/build logs
- deployment URL
- run receipts
- issue/debug report

### Sell loop

Purpose: build brand, website, ICP, competitor research, sales workflow,
outbound, pitch, and marketing loop.

| Work | Agent | Device |
|---|---|---|
| Brand story and values | Brand agent | No device |
| Website generation | Marketing/engineering agent | Sandbox |
| ICP and competitor map | Research agent | Sandbox for research artifacts |
| Lead list | Sales agent | Sandbox; computer if authenticated dashboard work |
| Outreach sequence | Sales agent | Connector plus approval |
| CRM workflow | Sales ops agent | Connector/computer |
| Content assets | Marketing agent | Sandbox |
| Campaign metrics | Marketing ops agent | Connector/computer |

Outputs:

- brand brief
- website/landing page
- ICP definition
- competitor map
- CRM pipeline
- lead list
- email sequence drafts
- content calendar
- marketing reports

### Scale loop

Purpose: improve the loops that already work: analytics, support, unit
economics, expansion, and operating cadence.

| Work | Agent | Device |
|---|---|---|
| Analytics instrumentation | Engineering/data agent | Sandbox |
| Funnel/retention analysis | Data agent | Sandbox |
| Support knowledge base | Support agent | Sandbox artifact workspace |
| Support triage | Support agent | Connector/computer with approval |
| Unit economics report | Finance agent | Sandbox |
| Expansion analysis | Strategy agent | No device or sandbox for report |
| Weekly operating review | Operations agent | Sandbox for generated report |

Outputs:

- analytics event plan
- funnel report
- knowledge base
- support decision trees
- unit economics dashboard/report
- expansion memo
- weekly operating review

## Reference architecture

---

## Open-repo patterns to borrow

| Repo | Pattern | MIOSA equivalent |
|---|---|---|
| `Miosa-osa/BusinessOS` | Full business workspace template with OSA terminal, modules, desktop UI, and business context | MIOSA starter template for customers building an agent-company or internal operator product |
| `stackblitz/bolt.new` | Browser-based prompt, run, edit, deploy app-builder | MIOSA app-builder UI over persistent sandbox, preview, artifacts, deployment |
| `agent-workspace-linux` | Separate hidden desktop/browser controlled through MCP | MIOSA Computer or local device with visible stream, pause, permissions, screenshots |
| `agent-orchestrator` | Parallel agents, status tracking, plugins, isolation, review loop | MIOSA agent sessions, child devices, event stream, runtime adapters, approvals |
| Heuresis templates | Runtime-agnostic markdown workspace with agents and decision rules | Persistent sandbox with `SYSTEM.md`, `agents/`, `skills/`, `runbooks/`, `artifacts/` |
| Nebula devices | Shared virtual/local devices for agents and teammates | MIOSA sandbox/computer/local device with primary device policy |

## Product implementation checklist

1. Choose the product family: app builder, artifact factory, agent-company,
   virtual device, browser operator, or hybrid.
2. Define workspace, project, app, and company records.
3. Define departments and agent roster when the product is an operator/company
   product.
4. Create a primary persistent sandbox for code, files, artifacts, and builds.
5. Add optional computer for browser, dashboard, screenshot, and visual QA work.
6. Store shared company context and library artifacts.
7. Add app/project task and roadmap models.
8. Dispatch prompts into assigned agents and devices.
9. Stream tool calls, files, commands, screenshots, previews, and artifacts.
10. Add connector grants and managed secrets.
11. Add approval gates.
12. Add credit estimates and ledger entries.
13. Add snapshots, forks, and rollback.
14. Add deploy and Docker Host for public apps.
15. Add recurring jobs for support, analytics, marketing, and monitoring.
16. Add audit receipts for every external action.

---

## What requires a device

Not every agent needs a sandbox or computer. Use the smallest runtime that can
complete the task safely.

| Task | Recommended runtime | Why |
|---|---|---|
| Research summary, sales copy, planning, brainstorming | Model-only or hosted OSA run | No filesystem, browser login, package install, or long-running state is required |
| Generate DOCX/PDF/image artifacts | Sandbox | The agent needs libraries, files, previews, and downloadable outputs |
| Build a Next.js app, run tests, start a live preview | Persistent sandbox | Code and dependencies must live in `/workspace` across sessions |
| QA a signup flow in a real browser | Computer | The agent needs Chromium, clicks, forms, screenshots, and browser state |
| Log into customer dashboards | Computer with approvals and scoped connectors | Browser/session state and risky actions need auditability |
| Run 100 background research agents | Sandbox pool or job queue | The system needs isolation, concurrency limits, and resumable state |
| Control a user-owned machine or private network resource | Local device / BYOC / OpenComputer | Data or network access cannot leave the customer's environment |

The product should choose the runtime automatically, but users should see which
device is doing the work.

Description: The end-to-end lane from runtime profile to artifact export, the prompt-to-device flow, how env and secrets are inherited, and how agent outputs become downloads.

# Runtime profiles and artifacts

This page covers the runtime mechanics of an agent product: how a run starts from a runtime profile, how a prompt reaches a device, how environment and secrets are inherited, and how generated files become user-facing downloads.

## E2E runtime profile to artifact export

This is the concrete end-to-end lane to implement first for a Polsia, Cofounder, Nebula, Heuresis, BusinessOS, Lovable, Replit, Genspark, Emergent, or Blackbox AI-style product:

```text
create runtime profile
  -> create or resume sandbox/computer
  -> dispatch Agent Run with profile id
  -> agent writes files in /workspace
  -> export approved artifact paths
  -> store download URL on your product run record
```

```bash
PROFILE_ID=$(miosa api POST /agent-runtime-profiles -d '{
  "workspace_id": "ws_123",
  "name": "Default app builder",
  "runtime": "claude-code",
  "tools": ["files", "exec", "previews", "artifacts"],
  "connectors": ["anthropic/workspace-claude"],
  "env": {"ANTHROPIC_MODEL": "claude-sonnet-4.6"},
  "is_default": true
}' | jq -r '.data.id')

SANDBOX_ID=$(miosa create builder-box \
  --template nextjs \
  --wait \
  --json | jq -r '.id // .data.id')

miosa prompt \
  --sandbox "$SANDBOX_ID" \
  --harness claude-code \
  "Build a lead-capture page, run tests, and write the final bundle to /workspace/dist."

miosa files cp -r "$SANDBOX_ID":/workspace/dist ./lead-capture --json
```

```typescript
const profile = await miosa.agentRuntimeProfiles.create({
  workspaceId: "ws_123",
  name: "Default app builder",
  runtime: "claude-code",
  tools: ["files", "exec", "previews", "artifacts"],
  connectors: ["anthropic/workspace-claude"],
  env: { ANTHROPIC_MODEL: "claude-sonnet-4.6" },
  isDefault: true,
})

const sandbox = await miosa.sandboxes.create({
  templateId: "nextjs",
  agentRuntimeProfileId: profile.id,
})

  cwd: "/workspace",
  prompt:

  metadata: { productRunId: "run_123" },
})

const exportInfo = await sandbox.createExport({
  paths: ["/workspace/dist"],
  label: "lead-capture-build",
})

await saveProductRunArtifact(run.id, exportInfo.archiveDownloadUrl)
```

```python
profile = client.agent_runtime_profiles.create(
    workspace_id="ws_123",
    name="Default app builder",
    runtime="claude-code",
    tools=["files", "exec", "previews", "artifacts"],
    connectors=["anthropic/workspace-claude"],
    env={"ANTHROPIC_MODEL": "claude-sonnet-4.6"},
    is_default=True,
)

sandbox = client.sandboxes.create(
    template_id="nextjs",
    agent_runtime_profile_id=profile["id"],
)

run = client.agent_runs.run(
    sandbox_id=sandbox.id,
    agent_runtime_profile_id=profile["id"],
    provider="claude-code",
    cwd="/workspace",
    prompt=(
        "Build a lead-capture page, run tests, and write the final bundle "
        "to /workspace/dist."
    ),
    metadata={"product_run_id": "run_123"},
)

export_info = sandbox.create_export(
    ["/workspace/dist"],
    label="lead-capture-build",
)

  --output lead-capture.tar.gz
```

Use a sandbox for generated files, reports, code, previews, and app bundles. Add
a computer step only when the run needs browser interaction, screenshots, or
visual QA. Use [Files, exec, and artifacts](/docs/develop/files-and-exec/) to
promote approved paths into downloads, and [Agent Runtime Profiles](/docs/api-reference/agent-runtime-profiles/)
for the reusable profile contract.

---

## Prompt-to-device flow

Use one product-level run model whether the user is building an app, generating
a report, or asking an operator to complete a business task.

```text
prompt
  -> resolve workspace and agent
  -> select runtime profile
  -> select sandbox, computer, or BYOC/OpenComputer target
  -> inject scoped env and secrets
  -> stream events while the device works
  -> save files, screenshots, artifacts, preview URLs, and deploy outputs
```

For Lovable, Replit, Genspark, Emergent, or Blackbox AI-style app builders, the default target should be a
persistent sandbox. The agent writes files into `/workspace`, runs install and
build commands there, starts a preview server, fixes errors in place, exports
deliverables, and publishes only after the user or browser QA approves the
result.

For Polsia or cofounder.co-style company operators, the same flow starts from a
business task instead of an app prompt. The orchestrator may use a sandbox for
documents and code, a computer for browser work, and BYOC/OpenComputer when the
task must run on customer-owned infrastructure.

## Runtime profiles and env inheritance

Runtime profiles keep the agent harness separate from the device. A profile
answers: which runtime starts, which tools are allowed, which non-secret env
defaults are present, and which connectors or secret groups can be requested.

Recommended resolution order:

| Source | Purpose |
|---|---|
| Tenant default profile | Platform-wide fallback for new workspaces |
| Workspace default profile | Customer/company-specific runtime choice |
| Agent profile | Role-specific tools, model, instructions, and connectors |
| Run override | One task's prompt, cwd, timeout, and non-secret env overrides |

Environment and secrets should be inherited narrowly:

| Value type | Inheritance rule |
|---|---|
| Non-secret env | Tenant defaults -> workspace defaults -> profile env -> run env |
| MIOSA runtime token | Minted per run or session with workspace/user/run attribution |
| Provider secrets | Resolved through managed secrets or connectors, never copied into chat |
| Browser-visible config | Only short-lived preview/share tokens and public config |
| BYOC/OpenComputer host secrets | Stay on the customer-owned host unless explicitly brokered |

If a value can spend money, access customer data, publish externally, or call a
provider API, treat it as a secret or connector grant instead of plain profile
env.

## Artifacts and downloads

Every agent run should end with named outputs, not just terminal text. Use
exports for files users should download and store the returned descriptor on
your product's run, task, or project record.

| Output | Device that produces it | User-facing surface |
|---|---|---|
| Generated app | Sandbox | Preview URL, deployment URL, source ZIP |
| PDF/DOCX/report | Sandbox | Artifact card with download button |
| Screenshot set | Computer | QA evidence and downloadable images |
| Research bundle | Sandbox | Markdown/CSV/ZIP artifact |
| Customer-local result | BYOC/OpenComputer | Host-side file plus brokered export if approved |

See [Files, exec, and artifacts](/docs/develop/files-and-exec/) for the export
API shape.

[Build an agent-company platform](/docs/guides/build-agent-company/) covers the orchestrator, runtime, and device modules this lane plugs into, and [Agent orchestration](/docs/guides/agent-orchestration/) covers running many of these at once.

# Agent device selection

URL: https://miosa.ai/docs/guides/agent-device-selection
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-device-selection
Source: src/routes/docs/guides/agent-device-selection/+page.md
Description: Decide when an agent needs no device, a sandbox, a computer, a local device, or a deployment target.

# Agent device selection

Not every agent needs a sandbox. The right question is:

```text
Does this agent need an execution environment, durable state, files, browser,
private network access, or deployable output?
```

If the answer is yes, assign a device. If the answer is no, the agent can run
as a lightweight orchestration or reasoning step in your backend.

---

## The short rule

| Agent task | Device |
|---|---|
| Pure reasoning, classification, routing, summarization | No device required |
| Write files, run code, install packages, generate artifacts | Sandbox |
| Browse websites, log in, click buttons, capture screenshots | Computer |
| Use customer-owned files, apps, VPNs, or private network | Local device |
| Serve production traffic | Deployment or Docker Host |

An agent can run without a sandbox when it only needs model reasoning and
backend-provided context. That is cheaper and faster. Give it a device only when
the work requires one.

---

## When no device is required

Use no device for agents that only need to think, classify, plan, or transform
text already available to your backend.

Examples:

- route a user prompt to the right department agent
- summarize a short transcript
- classify support tickets
- draft a simple sales email from provided context
- decide whether a run needs human approval
- select the best device for a task
- produce a task plan without touching files
- score leads using fields already in your database

This work can run in the product backend or in a managed MIOSA agent runtime
without creating a sandbox.

Billing is usually model/runtime usage only.

---

## When a sandbox is required

Use a sandbox when the agent needs a workspace.

Examples:

- write or edit code
- run tests or builds
- install npm, Python, Go, or system packages
- generate PDFs, DOCX, images, reports, CSVs, or ZIPs
- keep files between sessions
- run scripts or notebooks
- start a dev server
- expose a preview URL
- snapshot or fork state
- prepare a deployable app
- run a crawler, parser, or data pipeline

Research agents need a sandbox when they move beyond "read and summarize" into
work such as crawling, extracting, transforming, storing, charting, or producing
downloadable research artifacts.

Sales copy agents need a sandbox when they generate landing pages, proposals,
brand assets, email sequence files, spreadsheet exports, or versioned campaign
artifacts.

---

## When a computer is required

Use a computer when the agent needs a real browser or desktop.

Examples:

- log in to a dashboard
- test signup or checkout
- click through a SaaS UI
- fill forms
- inspect visual layout
- capture screenshots
- use a browser extension
- access a desktop-only workflow
- verify a preview like a human

Computers are more expensive than pure model runs and usually more expensive
than lightweight sandbox work. Use them when browser or desktop state matters.

---

## When a local device is required

Use a local device when the agent must work with customer-controlled resources
that should not move into the cloud.

Examples:

- local files that cannot be uploaded
- private network or VPN access
- installed desktop applications
- hardware-attached workflows
- local credential stores
- customer-controlled browser profiles

Local devices should be opt-in and visible. Users should know which workspace,
agent, and session can access their machine.

---

## When deployment is required

Deployment is not an agent workspace. It is the durable target after development
work is complete.

| Need | Target |
|---|---|
| Share a live dev preview | Sandbox preview |
| Serve a production app | MIOSA Deploy |
| Host many small apps for one workspace | Docker Host |
| Run an always-on agent workspace | Persistent sandbox or computer, not deployment |

Docker Host is where a verified app container runs. It is not where the agent
should be editing files.

---

## Examples by agent role

### Research agent

| Research task | Device |
|---|---|
| Summarize provided notes | No device |
| Search public web and write a brief answer | No device or sandbox, depending on tool policy |
| Crawl many pages and dedupe results | Sandbox |
| Generate charts and CSV report | Sandbox |
| Log in to a private analytics dashboard | Computer |
| Use a customer VPN-only database | Local device |

### Sales copy agent

| Sales task | Device |
|---|---|
| Draft email copy from CRM fields | No device |
| Generate a campaign brief artifact | Sandbox |
| Build a landing page | Sandbox |
| Preview and visually QA page | Sandbox plus computer |
| Send campaign through CRM/email tool | Connector with approval |
| Log in to ad platform and configure campaign | Computer with approval |

### Engineering agent

| Engineering task | Device |
|---|---|
| Explain a stack trace pasted into chat | No device |
| Edit code and run tests | Sandbox |
| Start a dev server | Sandbox |
| Verify browser UI | Computer |
| Publish production app | Deployment after approval |

### Support agent

| Support task | Device |
|---|---|
| Draft reply from ticket text | No device |
| Search internal docs and produce answer | No device or sandbox |
| Inspect account in web admin dashboard | Computer |
| Generate customer export file | Sandbox |
| Send reply | Connector with approval or policy |

---

## Decision tree

---

## Cost and performance guidance

| Choice | Startup | Cost | Best for |
|---|---|---|---|
| No device | Fastest | Lowest | Routing, planning, summarization |
| Sandbox | Fast | Medium | Code, files, artifacts, previews |
| Computer | Slower | Higher | Browser/desktop automation |
| Local device | Depends on user machine | Relay/model/tool cost | Private resources |
| Deployment | Build/publish dependent | Hosting cost | Durable production apps |

Start with the cheapest runtime that can safely complete the job. Escalate to a
sandbox, computer, or local device only when the task requires it.

---

## Backend routing policy

Your backend should make device selection explicit:

```typescript
type DeviceDecision = {
  required: boolean;
  deviceType?: "sandbox" | "computer" | "local";
  reason: string;
  needsApproval: boolean;
  estimatedCredits: number;
};
```

Record the decision with the run. If a run fails because the wrong device was
chosen, the recovery path should say which device class to retry with.

# Agent devices

URL: https://miosa.ai/docs/guides/agent-devices
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-devices
Source: src/routes/docs/guides/agent-devices/+page.md
Description: MIOSA's device model for agent work: sandbox workers, computers, local devices, primary devices, persistence, and Docker Host boundaries.

# Agent devices

Devices are the machines agents use to do real work. MIOSA has three active
device classes and one hosting target:

| Type | Product meaning |
|---|---|
| Sandbox Worker | Isolated code/file/build/preview/artifact workspace |
| Computer | Persistent cloud desktop/browser with screenshot and input APIs |
| Local Device / BYOC / OpenComputer | Paired user-owned host for local files, apps, private network access, or customer-owned capacity |
| Docker Host | Durable app-container host after development is finished |

Docker Host is not where an agent edits code. It is where a verified
sandbox-built app runs as a durable container.

---

## Choosing a device

Which runtime a task needs is a decision of its own. [Agent device selection](/docs/guides/agent-device-selection/) covers the decision rule, per-role examples, the decision tree, and cost guidance. This page describes the device model  -  what each device class is and how they relate.

A single run can use more than one runtime. For example, a sandbox can build an
app, a computer can test the preview, and an OpenComputer can call a private
internal service before the final artifact is exported.

---

## How devices relate

Diagram:
flowchart LR
  A[Agent] --> P[Device policy]
  P --> S[Sandbox Worker]
  P --> C[Computer]
  P --> L[Local Device]
  S --> Art[Artifacts and previews]
  C --> Shot[Screenshots and browser state]
  L --> Local[Private files and network]
  Art --> D[Deployment or Docker Host]

The agent can switch devices during a run. For example, a sandbox writes a web
app, a computer opens the preview and checks it visually, then the sandbox
publishes the verified result.

---

## Sandbox Worker

A sandbox is the normal runtime for coding agents.

### Sandbox capabilities

- persistent `/workspace`
- file read/write/list/delete
- Bash, Python, Node, package managers
- long-running dev servers
- public preview URLs
- snapshots and forks
- generated artifacts
- deploy and Docker Host publish prep
- scoped environment variables and connectors

Use a sandbox to build products like app builders, artifact factories, research
workspaces, evaluation runners, and code agents.

---

## Computer

A computer is a full desktop/browser runtime.

### Computer capabilities

- screenshot
- click, type, scroll, drag
- clipboard
- window control
- browser sessions
- visual QA
- terminal and shell
- persistent storage
- embeddable desktop stream

Use a computer when the job requires a visible browser, GUI automation, manual
handoff, or desktop-only software.

---

## Local Device / BYOC / OpenComputer

A local device is a paired machine owned by the user or tenant. In MIOSA docs
you will also see this path called BYOC or OpenComputers.

Use it when an agent needs:

- local files that cannot be uploaded
- private network access
- installed desktop apps
- local credentials that should not leave the machine
- customer-controlled hardware
- local GPUs or other host-specific capacity

Local devices are powerful but should be opt-in. The user should see exactly
which workspace and agent can reach the device. The device connects outbound to
MIOSA  -  no inbound ports are required.

---

## Primary device

Each workspace should have a primary device policy. Agents use it by default
when a task does not specify a runtime.

Recommended primary-device policies:

| Workspace type | Primary policy |
|---|---|
| App builder | Sandbox Worker |
| Browser automation workspace | Computer |
| Enterprise RPA | Computer, with BYOC/OpenComputer fallback |
| Customer-owned coding workspace | Persistent sandbox |
| Artifact factory | Sandbox Worker |

The primary device can change over time, but historical runs should still
record which device actually executed each action.

---

## Persistence

Agent work should survive normal stops.

| Runtime | Expected behavior |
|---|---|
| Persistent sandbox | Timeout stops compute and preserves state for resume |
| Non-persistent sandbox | Timeout destroys state |
| Computer | Stop/start preserves filesystem and desktop state |
| BYOC/OpenComputer | State stays on the customer-owned host unless the task exports it |
| Docker Host | App keeps running as a deployment until stopped or replaced |

For agent-building workflows, persistent sandbox should be the default. Use
non-persistent only for one-off untrusted jobs where the filesystem should be
discarded.

---

## Activity and timeout

Active agent work should reset the idle clock:

- exec calls
- file writes
- terminal input
- preview traffic
- browser/computer actions
- artifact generation
- deployment publish
- explicit extend calls

The UI and CLI should warn before a device is paused or destroyed. Long-running
workflows should create snapshots at stable checkpoints.

---

## Device permissions

Device access should be explicit:

| Permission | Example |
|---|---|
| `devices:use` | Run commands or browser actions on an assigned device |
| `devices:create` | Create child sandboxes or computers |
| `devices:destroy` | Permanently delete a device and saved state |
| `devices:connect-local` | Pair or use a local device |
| `devices:set-primary` | Change workspace default device policy |
| `deployments:publish` | Promote workspace output to durable hosting |

High-risk permissions should be gated by owner/admin roles or human approval.

---

## Building virtual-device products

With these primitives, you can build products that look like an always-on agent
workspace:

```text
Workspace
  -> primary sandbox for code and files
  -> optional computer for browser/desktop
  -> connected accounts and managed connectors
  -> jobs and schedules
  -> artifacts and previews
  -> deployment targets
```

This supports products like:

- 24/7 research agents
- browser automation workers
- AI app builders
- cofounder-style task operators
- artifact generation studios
- agent teams with shared files
- customer-owned coding workspaces

For Lovable/Replit/Genspark-style app builders, make the sandbox the primary
device and attach a computer only for browser QA or login-heavy checks. For a
Nebula-style virtual device, make the primary device visible in the UI so users
understand whether the current work is happening in a sandbox, a computer, or a
customer-owned OpenComputer.

Description: The CLI and release workflow for AI agents using MIOSA.

# Agent operating guide

Use this page when an AI agent, coding assistant, CI worker, or operator needs to build and release software through MIOSA.
The CLI is the authoritative happy path - prefer its `--json` output over reconstructing lower-level API calls.

## 1. Discover the current inventory

```bash
miosa catalog --json
miosa deploy list --json
miosa deploy get <deployment> --json
```

`catalog` reports the canonical compute products, templates, sizes, and readiness the platform offers right now.
`deploy list` and `deploy get` return the deployments you already own.
Do not guess a resource id from an old transcript when these commands can return the current inventory.

## 2. Develop in a persistent sandbox

```bash
miosa create my-dev-box --template nextjs --wait
miosa console my-dev-box --cwd /workspace
miosa doctor
miosa preview create my-dev-box 3000 --name candidate
```

`create` provisions the sandbox and, with `--wait`, blocks until it is ready.
`console` opens an interactive shell and resumes the same machine on a later run.
`doctor` checks configuration, connectivity and authentication.
Preview publishes a port at a public URL and never promotes production.

## 3. Publish the exact release

```bash
miosa deploy create my-app --from-sandbox my-dev-box --port 3000 --wait --json
miosa deploy releases <deployment>
miosa deploy promote <deployment> <release>
```

```typescript
const result = await miosa.deployments.publish(deploymentId, {
  sourceSandboxId: sandbox.id,
  kind: "auto",                       // "static" | "dynamic" | "auto"
  environment: "production",
  outputPath: "/workspace",
  runCommand: "npm start",            // dynamic deployments only
  port: 3000,                         // dynamic only
})

console.log(result.deployment.public_url)
```

```python
result = miosa.deployments.publish(
    deployment_id,
    source_sandbox_id=sandbox_id,
    kind="auto",              # "static" | "dynamic" | "auto"
    environment="production",
    output_path="/workspace",
    run_command="npm start",         # dynamic only
    port=3000,                       # dynamic only
)

print(result.deployment.public_url)
```

A candidate is not production merely because its build succeeded.
Promotion targets one exact immutable release, and the production URL stays stable while the active release changes.

# Agent orchestration

URL: https://miosa.ai/docs/guides/agent-orchestration
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-orchestration
Source: src/routes/docs/guides/agent-orchestration/+page.md
Description: How to coordinate multiple agents across MIOSA sandboxes, computers, artifacts, previews, events, and deployments.

# Agent orchestration

MIOSA lets you build agent systems where different agents use the right runtime
for each part of the job.

- A **sandbox agent** writes code, edits files, runs commands, builds packages,
  generates artifacts, and exposes preview ports.
- A **computer agent** uses a real browser or desktop for visual checks, clicks,
  form fills, screenshots, uploads, and human handoff.
- A **deployment agent** promotes a verified sandbox workspace into a production
  deployment or Docker Host app.
- Your **orchestrator** owns the task graph, model calls, permissions, retries,
  and user-facing progress stream.

The agents communicate through MIOSA-managed state: files, artifacts, events,
preview URLs, screenshots, snapshots, and deployment records.

If you are building an agent-company product, treat this as the platform layer:
agents are configured workers, devices are the execution substrate, connectors
grant tools, and events/artifacts make the work visible to users. See
[What MIOSA agents can do](/docs/guides/agent-capabilities/),
[Configure an agent](/docs/guides/configure-agent/), and
[Agent devices](/docs/guides/agent-devices/) for the product model before
scaling the orchestration layer.

For the end-to-end product blueprint, including Polsia-style company operators,
Cofounder (cofounder.co)-style department agents, Nebula-style virtual devices,
Heuresis-style encoded workspaces, and prompt dispatch into devices, see
[Build an agent-company platform](/docs/guides/build-agent-company/).

---

## Scale model: from one agent to thousands

The same primitives work for one agent, one hundred agents, or thousands of
agents, but the orchestration shape changes.

| Scale | Recommended shape |
|---|---|
| 1-10 agents | Direct agent loop creates/resumes sandboxes as needed |
| 10-100 agents | Queue-backed orchestrator with sandbox pools and per-workspace limits |
| 100-1,000 agents | Sharded job queues, regional sandbox pools, scoped tokens, explicit concurrency controls |
| 1,000+ agents | Dedicated tenant capacity, rate-limit contracts, batch APIs, event aggregation, and backpressure |

Do not start 10,000 independent sandboxes just because there are 10,000 logical
agents. Most products should distinguish:

- **Logical agent**: a model/tool loop or task worker in your application.
- **Runtime session**: a sandbox or computer doing actual work.
- **Workspace**: the persistent filesystem, secrets, snapshots, usage, and
  attribution boundary.

Many logical agents can share a queue and borrow runtime sessions from a pool.
Only the agents doing active code/browser work need a running sandbox or
computer at that moment.

---

---

## Mental model

The orchestrator should not make every agent share one messy machine. Instead,
each runtime does the work it is good at and emits durable outputs that the next
agent can consume.

---

---

## Runtime selection

| Job | Runtime | Why |
|---|---|---|
| Write app code | Sandbox | Fast headless Linux workspace with files and exec |
| Install dependencies | Sandbox | Dependency state stays in `/workspace` and snapshots |
| Run tests/builds | Sandbox | Deterministic command execution and streamed output |
| Serve a preview | Sandbox | Expose app ports as preview URLs |
| Inspect a browser UI | Computer | Real browser, screenshots, mouse, keyboard |
| Test signup/login flows | Computer | Cookies, popups, OAuth, uploads, and visual state |
| Generate PDFs/DOCX/images | Sandbox | Python/Node generators produce artifacts |
| Use private local systems | BYOC/OpenComputer | Data, network, apps, or local GPU capacity stays on the customer host |
| Publish production app | Deployment or Docker Host | Stable URL, versions, rollback, routing |

Do not collapse sandboxes and computers into one concept. Sandboxes are for
headless code and artifacts. Computers are for GUI/browser work. Orchestration is
the layer that lets them cooperate.

---

---

## Communication primitives

Use explicit handoffs instead of hidden shared memory.

| Primitive | Producer | Consumer | Example |
|---|---|---|---|
| File | Sandbox agent | Sandbox agent, deployment agent | `/workspace/app/page.tsx` |
| Artifact | Sandbox agent | User, another agent | `proposal.pdf`, `chart.png` |
| Preview URL | Sandbox agent | Computer agent, user | `https://3000-...sandbox.miosa.ai` |
| Screenshot | Computer agent | Orchestrator, LLM | Browser QA finding |
| Event | Any runtime | UI, orchestrator | stdout, stderr, file changed, preview ready |
| Snapshot | Sandbox | Sandbox agent | checkpoint before risky refactor |
| Deployment | Deployment agent | User, support | durable production URL |

The orchestrator should store these as run state so the frontend can replay what
happened and the next agent has a clean input.

---

---

## Queue and pool architecture

For high-scale orchestration, put a queue in front of MIOSA runtimes.

The queue owns backpressure. The runtime pool owns capacity. The orchestrator
owns task assignment. MIOSA owns isolated execution.

Use this pattern when:

- thousands of user tasks may arrive at once
- agents do bursty work
- you need to cap spend
- you need per-customer fairness
- you need reliable retries and dead-letter queues
- users need live progress without polling every runtime directly

---

---

## When to use ADK vs your own orchestrator

Use the [ADK](/docs/adk/) when you want MIOSA's built-in tool catalog and a
simple agent loop.

Build your own orchestrator when you need:

- multiple agents with different responsibilities
- product-specific UI events
- custom approval steps
- background jobs and retries
- per-user quotas and billing
- white-label attribution
- durable run history in your product layer

The orchestrator is your product layer. MIOSA is the runtime layer.

Description: Worked orchestration flows on MIOSA: an app builder with browser QA, a sandbox-first code agent, a computer QA agent, a minimal orchestrator shape, and the product UI pattern.

# Orchestration examples

Concrete flows that show the coordination patterns in action, from a full app builder with browser QA down to the minimal orchestrator shape and the UI it feeds.

---

## Example: app builder with browser QA

This is the pattern behind AI app-builder products. The user sees one task, but
the orchestrator splits it across code, browser, and deployment agents.

---

---

## Sandbox-first code agent

The code agent should build inside the sandbox rather than building locally and
uploading only at the end.

```text
get_or_create persistent sandbox
write files under /workspace
run install/build/test inside sandbox
start preview server
stream stdout/stderr to product UI
snapshot after meaningful progress
publish when verified
```

This is the loop that makes MIOSA useful for coding agents.

---

---

## Computer QA agent

Use a computer agent when the output needs visual/browser inspection.

```text
open preview URL
capture screenshot
click through navigation
fill a form
test login or signup
capture errors
return screenshot and findings to orchestrator
```

The browser agent should not edit code directly. It reports findings. The
sandbox agent patches the code.

---

---

## Minimal orchestrator shape

```typescript
type RuntimeHandoff =
  | { type: "file"; path: string }
  | { type: "preview"; url: string; port: number }
  | { type: "artifact"; path: string; mimeType?: string }
  | { type: "screenshot"; computerId: string; url: string }
  | { type: "deployment"; url: string; deploymentId: string };

type AgentStep = {
  id: string;
  agent: "sandbox" | "computer" | "deploy";
  status: "queued" | "running" | "succeeded" | "failed";
  input: Record<string, unknown>;
  output?: RuntimeHandoff[];
};
```

```python
from typing import Literal, TypedDict

class RuntimeHandoff(TypedDict, total=False):
    type: Literal["file", "preview", "artifact", "screenshot", "deployment"]
    path: str
    url: str
    port: int
    deployment_id: str

class AgentStep(TypedDict, total=False):
    id: str
    agent: Literal["sandbox", "computer", "deploy"]
    status: Literal["queued", "running", "succeeded", "failed"]
    input: dict
    output: list[RuntimeHandoff]
```

---

---

## Product UI pattern

An orchestrated MIOSA product usually has three panels:

| Panel | Shows |
|---|---|
| Chat / task stream | Reasoning summary, tool calls, command output, status updates |
| Workspace / preview | Live sandbox preview, computer desktop, screenshots, logs |
| Artifacts | Generated files, screenshots, PDFs, DOCX, ZIPs, deployment URLs |

Good progress events include:

- plan created
- sandbox created or resumed
- file written
- command started
- stdout/stderr chunk
- command completed
- preview ready
- screenshot captured
- artifact created
- deployment started
- deployment ready

# Orchestration patterns

Source: src/routes/docs/guides/agent-orchestration/patterns/+page.md
Description: Coordination patterns for MIOSA agent systems: prompt dispatch, durable run groups, subagents, sandbox-hosted orchestrators, self-configuring agents, artifact export, credentials, and permissions.

# Orchestration patterns

These are the coordination patterns that make an agent system work as it grows: how a prompt reaches the right device, how a task fans out into durable run groups, in-sandbox and sandbox-hosted topology, how generated work leaves the runtime, and how credentials and permissions stay scoped.

---

## Prompt dispatch

At runtime, orchestration mostly means dispatching prompts into the right
device and streaming the result back.

| Prompt target | Use it for | Example command |
|---|---|---|
| Sandbox | code, files, tests, builds, artifacts, preview servers | `miosa prompt --sandbox <id> "build the page"` |
| Computer | browser, screenshots, clicks, form fill, visual QA | `miosa prompt --computer <id> "test signup"` |
| BYOC/OpenComputer | private local files, apps, network, customer-controlled hardware | See [OpenComputers](/docs/opencomputers/) for host-scoped work |

Create reusable runtime profiles for the agents your product supports. A
profile can be tenant-wide or workspace-specific, and it can apply to sandbox
workers, computer agents, or both.

Prompt-to-device flow should be explicit in your product backend:

```text
user prompt
  -> product run record
  -> runtime profile resolution
  -> sandbox, computer, or BYOC/OpenComputer target
  -> scoped env and secret injection
  -> event stream
  -> files, artifacts, screenshots, previews, deployments
```

This lets Polsia-style operators, cofounder.co-style company operating systems,
Nebula-style virtual devices, and Lovable/Replit/Genspark-style app builders
share one UI contract even when they use different runtimes underneath.

### Durable run groups

Use an Agent Run Group when one product task fans out into multiple child runs.
The group gives your UI one durable record for counts, status, cancellation,
child run lookup, and a group event stream.

```text
user task
  -> agent run group
    -> child run: sandbox coder
    -> child run: sandbox tester
    -> child run: computer browser QA
    -> child run: deployment verifier
  -> artifacts, events, previews, screenshots, deployment URL
```

Current dispatch batches are capped at 100 child runs per API call. For hundreds
or thousands of logical agents, queue the work in your backend and dispatch in
batches against one or more groups. Keep a separate concurrency policy per
tenant/workspace so one customer cannot consume the whole runtime pool.

The user-facing loop should be:

```text
create group
  -> dispatch child runs
  -> stream /agent-run-groups/{id}/events
  -> show child run status and output as it happens
  -> list artifacts from completed child runs
  -> expose download/preview/deploy actions in your UI
```

This avoids opening one browser stream per child agent. Your product backend can
subscribe to one group stream, normalize events into your own task timeline, and
keep the UI live while sandbox and computer agents work in parallel.

When a child run uses a sandbox process-backed runtime, cancellation stops the
recorded sandbox process instead of only changing run status. Use this for
longer build, test, scrape, or artifact-generation tasks where the user may
cancel from your UI.

        },

        },
    ],
    async_=True,
)

for event in client.agent_run_groups.stream_events(group["id"]):
    timeline.append(
        {
            "child_run_id": event["agent_run_id"],
            "type": event["type"],
            "message": event.get("message"),
        }
    )
```

If no explicit profile is passed, MIOSA resolves the workspace default profile
first, then the tenant default profile. Request-level `env` values override
non-secret profile defaults. Secret provider keys should come from managed
secrets or connectors, not from profile `env`.

Recommended inheritance order:

| Layer | Inherits into the run | Should not contain |
|---|---|---|
| Tenant default profile | Organization-wide runtime, tool, and non-secret env defaults | Customer-specific provider keys |
| Workspace default profile | Company/customer runtime choice, cwd defaults, allowed tools | Tenant admin keys |
| Agent profile | Role instructions, connectors, approval policy, model hints | Browser-visible secrets |
| Run request | Prompt, cwd, timeout, non-secret env overrides | Long-lived provider credentials |

Use managed secrets or connectors for anything that can spend money, access
customer data, publish externally, or call a provider API. The run should
receive a scoped MIOSA runtime token with tenant/workspace/user/run attribution,
plus brokered provider access only for the endpoints the profile allows.

Every dispatch should record:

- prompt
- runtime or harness
- device id
- scoped credentials and connectors
- approval policy
- streamed events
- files, artifacts, screenshots, previews, or deployment outputs

The user experience should be the same whether the prompt is handled by OSA,
Codex, Claude Code, Hermes, OpenCode, OpenClaw, or a custom runtime.

---

## Subagents inside sandboxes

You can also run subagents inside a sandbox. This is useful when the product
wants a primary orchestrator to delegate work into an isolated workspace.

```text
Account / tenant
  -> workspace
    -> orchestrator service
      -> sandbox
        -> subagent A: code editor
        -> subagent B: test runner
        -> subagent C: artifact generator
        -> subagent D: deploy verifier
```

The sandbox receives the environment and scoped credentials it needs. The
subagents run inside `/workspace`, communicate through files, local processes,
stdout, and MIOSA events, and report results back to the orchestrator.

Good uses for sandbox-hosted subagents:

- parallel code review agents inside one repo
- test generation plus test execution
- report generation workers
- artifact conversion workers
- dependency install/build/lint/test pipelines

Avoid using one sandbox as an uncontrolled multi-tenant process host. A sandbox
should belong to one tenant/workspace/security boundary.

---

---

## Sandbox-hosted orchestrators

The orchestrator does not always have to live in your backend. A MIOSA sandbox
can be the root orchestrator workspace.

```text
Tenant account
  -> workspace
    -> root orchestrator sandbox
      -> orchestration config
      -> local subagents
      -> child MIOSA sandboxes
      -> child MIOSA computers
      -> artifacts
      -> previews
      -> deployments
```

This pattern is useful for autonomous coding systems, research systems,
artifact factories, and customer-owned agent runtimes. The root sandbox keeps
the project files, agent configuration, run history, and local tooling. The
orchestrator process inside that sandbox can call MIOSA to launch additional
sandboxes or computers when it needs isolated workers.

Good examples of this pattern:

- root sandbox runs an agent manager
- child sandbox builds a web app
- child sandbox runs tests in parallel
- child computer opens the preview in a browser
- root sandbox collects screenshots, logs, and artifacts
- deploy agent publishes the verified result

The backend still owns tenant enforcement, billing, quotas, audit logging, and
token minting. The sandbox-hosted orchestrator owns the local plan and execution
strategy for that workspace.

---

---

## Self-configuring agents

A sandbox-hosted orchestrator can customize its own setup. It can write config
files, install packages, create worker scripts, generate task definitions, and
adjust its local workflow as the project evolves.

Typical files inside `/workspace`:

```text
/workspace
  agent.config.json
  miosa.runbook.md
  tasks/
    build.json
    test.json
    browser-qa.json
  agents/
    coder.ts
    tester.ts
    artifact-generator.py
  artifacts/
  logs/
```

Example `agent.config.json`:

```json
{
  "workspace": "lumen-demo",
  "defaultTemplate": "nextjs",
  "workers": {
    "coder": { "runtime": "local", "tools": ["files", "exec"] },
    "tester": { "runtime": "child-sandbox", "template": "miosa-sandbox" },
    "browserQa": { "runtime": "computer", "template": "ubuntu-browser" }
  },
  "limits": {
    "maxConcurrentWorkers": 8,
    "maxChildSandboxes": 4,
    "maxChildComputers": 1
  }
}
```

This lets an agent improve its own operating procedure without requiring every
change to be hard-coded in the parent application.

Use these guardrails:

- keep config files visible in `/workspace`
- require explicit approval for quota or permission increases
- validate generated config before applying it
- cap child sandbox/computer creation
- write run events back to the product UI
- snapshot before major self-modification
- keep tenant admin credentials outside the sandbox

The goal is controlled autonomy: the agent can code and configure its own
workspace, but MIOSA still enforces account boundaries and resource limits.

---

---

## Exporting generated work

Agents should leave concrete outputs behind. For app builders and agent-company
products, those outputs become the user's deliverable: HTML, PDFs, DOCX files,
CSV exports, screenshots, ZIPs, source patches, build logs, or deployment URLs.

Use declared artifact paths on Agent Runs when you expect a generated file:

```json
{
  "sandbox_id": "sbx_code",
  "provider": "claude-code",
  "prompt": "Build the landing page and export /workspace/artifacts/site.html",
  "metadata": {
    "artifact_paths": ["/workspace/artifacts/site.html"]
  }
}
```

When the run completes, list and download artifacts:

```bash
miosa run files <run-id> --json
miosa run download <run-id> <file-id> --output ./site.html
```

MIOSA captures artifact bytes into managed storage when possible. If an
artifact has `persisted: true`, your UI can keep showing a download button after
the runtime stops. If it is not persisted, keep the sandbox or computer running
until the file has been downloaded, published, or copied somewhere durable.

Use this split in your product UI:

| Output type | Best surface |
|---|---|
| HTML, PDF, DOCX, CSV, ZIP | Artifact download |
| Web app | Sandbox preview, then deployment |
| Screenshot or visual QA result | Artifact preview plus event timeline |
| Source code changes | Files panel, git diff, artifact ZIP |
| Long-running product | Deployment or Docker Host URL |

---

---

## Credentials and account connection

Large agent systems should use scoped credentials instead of sharing one tenant
admin key everywhere.

```text
Tenant key
  -> server-side orchestrator only
  -> mints scoped workspace/user tokens
  -> tokens injected into sandbox/computer runtime
  -> subagents call MIOSA within their allowed scope
```

Typical environment injected into a runtime:

```bash
MIOSA_API_KEY=msk_scoped_...
MIOSA_TENANT_ID=...
MIOSA_WORKSPACE_ID=...
MIOSA_PROJECT_ID=...
MIOSA_USER_ID=...
MIOSA_RUN_ID=...
```

This lets every subagent be connected to the correct account while still giving
the platform auditability, quotas, and revocation.

Important credential rules:

- Browser code never receives tenant admin keys.
- Sandboxes receive scoped runtime keys, not root account keys.
- Every token has workspace/project/user/run attribution.
- Every command, file write, preview, snapshot, and deploy is auditable.
- Quotas apply at tenant, workspace, user, and runtime-pool levels.

---

---

## Permissions and safety

Each agent should receive only the permissions it needs.

| Agent | Typical permissions |
|---|---|
| Sandbox code agent | sandbox files, exec, previews, snapshots |
| Artifact agent | sandbox files, exec, artifact export |
| Browser QA agent | computer screenshot, click, type, navigation |
| Deploy agent | deployment publish, domains, rollback |
| Billing/support agent | usage, credits, audit log |

Use scoped workspace keys or server-side tokens. Do not put tenant admin keys in
browser code.

# Agent product model

URL: https://miosa.ai/docs/guides/agent-product-model
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-product-model
Source: src/routes/docs/guides/agent-product-model/+page.md
Description: The canonical MIOSA model for agents, devices, runs, tools, artifacts, credits, and deployments.

# Agent product model

MIOSA lets builders create products where agents do real work in cloud devices.
The product model is deliberately small:

```text
Agent + Device + Tools + Run stream + Artifacts + Credits
```

That model supports simple one-shot commands, generated app builders, browser
automation, artifact workspaces, 24/7 company operators, white-label SaaS
backends, and multi-agent fleets.

Use this page as the canonical vocabulary for products built on MIOSA.

---

## Core primitives

| Primitive | Meaning | Owned by |
|---|---|---|
| Agent | The worker identity: instructions, runtime, model, tools, memory, policy | Your product or MIOSA |
| Runtime | The implementation that reasons and acts: OSA, Codex, Claude Code, Hermes, Pi, custom | Agent configuration |
| Device | The machine where work happens: sandbox, computer, or local device | MIOSA |
| Run | A prompt dispatched to an agent on a device | Your product and MIOSA |
| Session | A long-lived run that can receive more tasks | Agent runtime |
| Tool | A capability: files, exec, browser, connector, deploy, artifact, MCP | Runtime and policy |
| Event | A streamed record of work: tool call, command output, file change, screenshot | MIOSA stream |
| Artifact | A durable output: file, image, PDF, DOCX, report, preview, app URL | MIOSA storage |
| Snapshot | Saved filesystem/device state for resume, fork, or rollback | MIOSA |
| Credits | The metering unit for model usage, device runtime, tools, storage, and hosting | Billing ledger |

The MIOSA agent is the reasoning/runtime layer. The device is where work
executes. A sandbox has an executor, but that executor is not the product agent.

---

## Boundary

Your product backend decides:

- who the user is
- what workspace, project, and budget apply
- which agent should run
- which runtime should power the agent
- which device the agent can use
- which tools and connectors are allowed
- which actions require approval
- how events appear in your UI

MIOSA provides:

- sandbox lifecycle
- computer lifecycle
- local-device pairing
- filesystem and exec APIs
- browser/desktop execution
- previews and routing
- snapshots and persistence
- artifacts and downloads
- deploy and Docker Host
- event streaming
- credit metering hooks

---

## Product categories


    The agent writes code inside a persistent sandbox, starts a preview, fixes
    errors, creates artifacts, and publishes the finished app.



    The agent creates PDFs, DOCX files, diagrams, images, reports, ZIPs, and
    HTML previews, then stores each output with version history.



    The agent uses a computer to click, type, log in, fill forms, inspect pages,
    capture screenshots, and verify workflows.



    Users and agents share persistent devices with files, browser state, jobs,
    previews, connected apps, and recoverable sessions.



    An orchestrator delegates work to department agents across sandboxes,
    computers, connectors, and scheduled jobs.



    Your platform routes prompts from your users into MIOSA resources while
    preserving your own workspace, project, and billing model.


---

## Product stack

Most MIOSA-powered products have the same layers:

| Layer | Responsibility |
|---|---|
| Product UI | Chat, tasks, files, artifacts, preview, approvals, usage |
| Product API | Auth, tenancy, workspace/project mapping, budgets, policies |
| Orchestrator | Agent selection, runtime routing, device assignment, queues |
| MIOSA devices | Sandboxes, computers, local devices, previews, snapshots |
| Tool layer | Files, exec, browser, connectors, egress, deploy, MCP |
| Event stream | Live progress, stdout, screenshots, artifacts, errors |
| Billing ledger | Credits by model, device, connector, storage, deployment |

The product UI should make the run visible. Users should see what the agent is
doing, not only a final chat answer.

Recommended panes:

- chat or task input
- current plan
- live tool calls
- command output
- file tree or artifact list
- preview/browser panel
- approvals
- credits used
- final outputs

---

## Canonical run shape

```typescript
type AgentRun = {
  id: string;
  tenantId: string;
  workspaceId: string;
  projectId?: string;
  userId: string;
  agentId: string;
  runtime: "osa" | "codex" | "claude-code" | "pi" | "hermes" | "custom";
  device: {
    type: "sandbox" | "computer" | "local";
    id: string;
  };
  prompt: string;
  status: "queued" | "running" | "waiting_for_approval" | "failed" | "completed";
  approvalPolicy: "auto" | "confirm-risky" | "manual";
  idempotencyKey: string;
};
```

Every run should have:

- one owner workspace
- one initiating user or service account
- one selected agent
- one primary device
- one idempotency key
- a typed event stream
- a credit ledger record
- a recovery path if it fails after creating resources

---

## Event stream

The event stream is what makes the product feel alive.

| Event | Purpose |
|---|---|
| `run.queued` | Request accepted and waiting for execution |
| `run.started` | Runtime and device assigned |
| `agent.message.delta` | Assistant text streaming to the UI |
| `plan.updated` | Agent created or changed the task plan |
| `tool.started` | Tool, MCP, connector, or device action started |
| `tool.completed` | Tool completed with result metadata |
| `command.output` | stdout/stderr chunks from exec |
| `file.changed` | File create/update/delete/rename |
| `preview.ready` | Live server URL passed readiness |
| `browser.screenshot` | Computer/browser image captured |
| `artifact.created` | Durable output available |
| `approval.required` | Human approval needed |
| `credits.estimated` | Expected cost for a risky action |
| `credits.charged` | Metering entry committed |
| `deployment.ready` | Public URL live |
| `run.failed` | Typed failure with recovery instruction |
| `run.completed` | Final answer and outputs are ready |

Do not build a product that hides all of this until the end. The visible stream
is how users trust that the agent is working.

---

## What gets billed

Credits should be metered by resource category:

| Category | Examples |
|---|---|
| Model | OSA/model tokens, external model calls, hosted agent runtime |
| Device runtime | Sandbox CPU/RAM time, computer time, local-device relay |
| Tooling | Browser actions, connector token requests, Refero design research, web search |
| Storage | Artifacts, snapshots, persistent workspace storage, logs |
| Deployment | MIOSA Deploy, Docker Host, domains, always-on apps |

This means the user does not need to understand every infrastructure detail.
They buy credits; credits power agents doing real work on devices.

# Agent runtime routing

URL: https://miosa.ai/docs/guides/agent-runtime-routing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-runtime-routing
Source: src/routes/docs/guides/agent-runtime-routing/+page.md
Description: How MIOSA routes prompts to OSA, Codex, Claude Code, Pi, Hermes, custom runtimes, and assigned devices.

# Agent runtime routing

An agent run has two separate choices:

1. **Which runtime thinks and acts?**
2. **Which device executes the work?**

The runtime can be OSA, Codex, Claude Code, Pi, Hermes, Gemini CLI, OpenCode,
or a custom agent harness. The device can be a sandbox, computer, or local
device.

```text
MIOSA Agent = runtime, model, instructions, tools, policy
MIOSA Device = sandbox, computer, or local machine where actions happen
```

---

## Routing contract

```typescript
type RuntimeRoute = {
  runtime: "osa" | "codex" | "claude-code" | "pi" | "hermes" | "gemini-cli" | "opencode" | "custom";
  model?: string;
  deviceType: "sandbox" | "computer" | "local";
  deviceId: string;
  cwd?: string;
  prompt: string;
  tools: string[];
  connectors: string[];
  approvalPolicy: "auto" | "confirm-risky" | "manual";
};
```

The runtime receives:

- prompt
- system instructions
- device tool handles
- connector handles
- allowed environment variables
- approval policy
- budget envelope

The device executes:

- file operations
- commands
- browser actions
- screenshots
- preview servers
- artifact generation
- deployment prep

---

## Runtime choices

| Runtime | Use it for | Notes |
|---|---|---|
| OSA | MIOSA-native general agent, white-label flows, managed products | Default platform runtime |
| Codex | Code-heavy sandbox work, repo edits, tests, CLI-native dev workflows | Best for software engineering loops |
| Claude Code | Code and artifact workflows where Claude Code is the customer's preferred harness | Needs non-interactive session support |
| Pi | Agent harness experiments and AI SDK-compatible streams | Useful when customer ecosystem expects Pi |
| Hermes | Specialized customer agent runtime | Treat as runtime adapter |
| Gemini CLI / OpenCode / custom | Customer-provided runtimes | Must satisfy MIOSA event/tool protocol |

Every runtime should adapt to the same MIOSA event stream. The frontend should
not need custom rendering logic for each agent runtime.

---

## Device choices

| Device | Runtime fit |
|---|---|
| Sandbox | OSA, Codex, Claude Code, Hermes, custom code agents |
| Computer | OSA, Claude Code, browser/desktop operators, QA agents |
| Local device | Customer-controlled runtimes, private network work, local-file workflows |

Recommended defaults:

- app builders: sandbox
- artifact generation: sandbox
- web QA: computer
- dashboard automation: computer
- private enterprise task: local device
- broad agent-company product: primary sandbox plus optional computer

---

## Non-interactive first

Interactive TUIs are useful for humans. They should not be the only reliable
execution path for a platform.

Production-grade runtime sessions should support:

- `--prompt` or prompt file input
- `--detach`
- JSON output
- reconnectable event stream
- explicit model selection
- clean cancel/stop
- typed errors
- no dependency on tmux for correctness

This is the difference between a CLI tool and a product substrate.

---

## Runtime adapter lifecycle

The adapter is responsible for translating runtime-specific behavior into
MIOSA's common protocol.

Examples:

| Runtime event | MIOSA event |
|---|---|
| Tool call started | `tool.started` |
| Shell output | `command.output` |
| File edit | `file.changed` |
| Browser screenshot | `browser.screenshot` |
| Artifact saved | `artifact.created` |
| Human confirmation needed | `approval.required` |
| Model/tool failure | `run.failed` |

---

## Model availability

The runtime should never silently default to an unavailable model. The product
must validate model availability before starting a session.

Recommended behavior:

1. List available models for the runtime.
2. Pick workspace default if valid.
3. Fall back to runtime default if configured.
4. Return a typed error with valid model options if unavailable.

Bad:

```text
Unknown model "x"
```

Good:

```json
{
  "code": "MODEL_UNAVAILABLE",
  "message": "claude-opus-4-7 is not available for this workspace.",
  "available_models": ["claude-sonnet-4.6", "claude-opus-4.6"],
  "recovery": "Retry with --model claude-sonnet-4.6."
}
```

---

## Credential injection

Runtimes often need provider credentials. The safe model is:

- users or admins store credentials in MIOSA
- runtime receives scoped handles, not raw platform admin keys
- sandboxes receive only the environment variables approved for that workspace
- egress swaps managed placeholders only for the intended provider endpoint
- all credential use emits audit events

Example:

```text
workspace stores ANTHROPIC_API_KEY
  -> agent policy allows Claude Code runtime
  -> sandbox session receives scoped runtime secret
  -> runtime can call provider
  -> UI never shows raw key
```

For managed connectors such as Refero, GitHub, Slack, Google, or tenant APIs,
prefer connector token exchange over plain environment variables.

# Agent safety and status

URL: https://miosa.ai/docs/guides/agent-safety
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-safety
Source: src/routes/docs/guides/agent-safety/+page.md
Description: How agents interpret deployment health, preserve durable resources, and respect current capability boundaries.

# Agent safety and status

An agent must not treat a single signal as proof that production is healthy, and must not replace durable resources on a guess.
This page covers status interpretation, durable-resource handling, and the current capability boundaries.

## Interpret status correctly

A deployment is not proven healthy from one database row, one HTTP response, or one host heartbeat.
The active release, running artifact, public route, data bindings, required capabilities, and runtime placement must agree.

| Signal | What it proves |
|---|---|
| Release status is `ready` | The immutable artifact can be considered for promotion |
| Build status is `succeeded` | The build step completed for this release |
| `active_release_id` matches | The control plane selected the expected release |
| The public route responds | Users can reach the deployed application surface |
| Runtime logs show healthy startup | The process bound its port and is serving |

## Preserve durable resources

A sandbox is a mutable development workspace.

A deployment is the durable production identity.

A managed database and its volume are durable data resources.

An Docker Host host can run multiple deployments and should not be replaced for an application-level failure without host-level evidence.

Pause, resume, recover, and reconcile existing resources before creating replacements.

Create a replacement only when the original resource is proven terminal and its state, bindings, and ownership have been preserved.

## Capability boundaries

MIOSA currently supports sandboxes, computers, previews, immutable application releases, managed data, workspace attribution, domains, integrations, and OpenComputers.

Specialized model APIs can be connected today.

CPU-compatible open-source applications can be self-hosted when their runtime requirements fit the selected compute.

Managed GPU execution and built-in managed agent orchestration remain planned until the availability page marks them shipped.

AWS and Google Cloud customer-region packages exist, but production activation remains gated on provider canary and host-acceptance evidence.

# Agent workflow patterns

URL: https://miosa.ai/docs/guides/agent-workflow-patterns
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/agent-workflow-patterns
Source: src/routes/docs/guides/agent-workflow-patterns/+page.md
Description: Simple-to-complex workflows for using MIOSA agents, devices, events, artifacts, and deployments.

# Agent workflow patterns

MIOSA workflows scale from a single prompt to a fleet of long-running agents.
The same primitives apply at every level:

```text
prompt -> agent runtime -> assigned device -> event stream -> durable output
```

Use this page to choose the right workflow for your product.

---

## Pattern 1: one-shot run

Use this for quick checks, small scripts, inspections, summaries, and health
tests.

```bash
miosa prompt --sandbox <sandbox-id> "check if the preview server is healthy"
```

Expected behavior:

1. CLI sends the prompt to MIOSA.
2. MIOSA validates the target sandbox.
3. Runtime executes a short task.
4. CLI prints the answer and any structured output.
5. Credits are charged for model usage and device time.

Use this when the user does not need a long-lived session.

---

## Pattern 2: prompt into a sandbox

Use this when the agent should code, generate artifacts, run tests, or start a
preview.

```bash
miosa prompt --sandbox <sandbox-id> \
  --harness codex \
  "Build a Next.js landing page, run it on port 3000, and fix any errors."
```

The agent should work inside `/workspace`:

- write files
- install dependencies
- run tests
- start dev server
- inspect errors
- save artifacts
- snapshot checkpoints
- publish when approved

Uploading a local repo is useful for import and sync. It should not be the only
agent workflow. The normal agent-builder path is to let the agent create and
modify files inside the sandbox.

---

## Pattern 3: prompt into a computer

Use this when the task requires a real browser, GUI, login flow, or visual QA.

```bash
miosa prompt \
  --computer <computer-id> \
  --harness claude-code \
  "Open the app preview, test signup, capture screenshots, and report issues."
```

The computer device can:

- open URLs
- click buttons
- type into forms
- scroll
- log in to dashboards
- inspect UI states
- take screenshots
- use terminal or desktop apps

Use a computer after a sandbox creates a preview, or as the primary runtime for
browser-heavy automation products.

---

## Pattern 4: detached agent session

Use this for tasks that continue after the first command returns.

```bash
miosa agent run builder \
  --sandbox <sandbox-id> \
  --no-follow \
  --json
```

Then inspect and continue the session:

```bash
miosa run events <run-id>
miosa run steer "Now add authentication and update the README." --sandbox <sandbox-id>
miosa run files <run-id>
miosa run stop <run-id>
```

Detached sessions should not require a terminal UI to keep running. A TUI is a
view, not the execution model.

Detached run requirements:

- run id returned immediately (`--no-follow`)
- events available over API and CLI
- reconnectable stream
- durable transcript (`miosa run messages`)
- artifacts linked to the run (`miosa run files`)
- clean stop/cancel (`miosa run stop`)
- typed failure state
- clear credit usage

---

## Pattern 5: app-builder loop

Use this for Lovable, Replit, v0, or Lumen-style app generation.

```text
User prompt
  -> create/resume sandbox
  -> agent edits files in /workspace
  -> run install/build/test
  -> start preview
  -> stream files and preview URL to UI
  -> user asks for edits
  -> agent patches same sandbox
  -> snapshot stable state
  -> publish to deployment
```

Recommended UI:

- chat
- file tree
- command log
- preview frame
- artifacts panel
- deployment status
- version history
- credit usage

Recommended backend records:

```sql
projects
  current_sandbox_id
  current_deployment_id
  latest_snapshot_id

agent_runs
  project_id
  sandbox_id
  prompt
  status
  idempotency_key
```

---

## Pattern 6: artifact workspace

Use this for Claude Desktop-style work where the agent creates documents,
images, diagrams, or data files.

Examples:

- proposals
- DOCX files
- PDFs
- pitch decks
- diagrams
- brand assets
- CSV reports
- HTML previews
- ZIP bundles

Flow:

```text
prompt -> sandbox -> generate file -> render/validate -> artifact -> version
```

The UI should show:

- live text/code generation
- generated file cards
- preview pane
- download button
- revision history
- "make changes" prompt attached to the artifact

---

## Pattern 7: browser operator

Use this for Nebula-style browser work or RPA-like workflows.

```text
prompt -> computer -> browser session -> screenshots/events -> report/action
```

Examples:

- fill onboarding forms
- verify checkout
- inspect admin dashboards
- scrape authenticated data
- test browser UI
- run visual QA on previews

Human approval should be required before:

- submitting external forms
- sending messages
- spending money
- deleting data
- changing account settings
- using admin credentials

---

## Pattern 8: orchestrated agent team

Use this for Cofounder (cofounder.co), Polsia, Agentfounder, or internal
operator products.

The orchestrator should:

- break the prompt into tasks
- assign devices and runtimes
- enforce budget and approvals
- stream each child run
- merge artifacts
- ask for human approval on risky actions
- produce one final status

Use child devices only when they create real leverage. Not every task needs a
new sandbox.

---

## Pattern 9: agent fleet

Use this when the product launches tens, hundreds, or thousands of workers.

Examples:

- large test matrices
- lead enrichment
- website audits
- browser QA sweeps
- benchmark runs
- research crawls
- parallel code migrations

Fleet requirements:

| Requirement | Why it matters |
|---|---|
| Queue | Avoid unbounded device creation |
| Idempotency | Retry without duplicate resources |
| Budget cap | Stop runaway spend |
| Concurrency limit | Protect user plan and platform capacity |
| Child-run events | Show progress without opening every worker |
| Aggregation | Merge output into one report |
| Cancellation | Stop the fleet fast |
| Partial results | Preserve useful work after failures |

---

## Choosing the pattern

| User asks for | Use |
|---|---|
| Quick check | One-shot run |
| Generate code | Sandbox prompt |
| Test browser flow | Computer prompt |
| Keep working after disconnect | Detached session |
| Build and preview app | App-builder loop |
| Make a document/image/report | Artifact workspace |
| Operate a website/dashboard | Browser operator |
| Run a company/project | Orchestrated agent team |
| Scale many workers | Agent fleet |

Description: Build your own Genspark, Emergent, Blackbox AI, Lovable, Replit, Polsia, Cofounder, or Nebula-style product on MIOSA.

# Build your own AI platform

You can use MIOSA to build your own product in the same category as **Genspark**, **Emergent**, **Blackbox AI**, **Lovable**, **Replit Agent**, **Polsia**, **Cofounder**, or **Nebula**.

Your product owns the brand, customer experience, prompts, model routing, billing, and workflow.
MIOSA supplies the execution layer: sandboxes, computers, files, commands, previews, artifacts, snapshots, connectors, events, data services, and immutable deployments.

This guide maps the product category to concrete MIOSA resources.
It covers prompt-to-app builders, autonomous company operators, agent workspaces, and persistent virtual-device products.
See the [Agent product reference map](/docs/guides/agent-company-reference-map/) for the reference products to study, then build your own implementation and brand here.

The orchestrator is your product layer. It decides which agent runs, what model
or harness powers it, which device it can use, which credentials are available,
when to ask for approval, and how progress appears to the user.

MIOSA is the runtime layer. It executes the work and records the outputs.

---

## Implementation checklist

Start with one workspace and one agent before scaling to teams or thousands of
workers.

| Step | MIOSA primitive | What to build in your product |
|---|---|---|
| 1. Create workspace | Workspace or white-label workspace | Customer/company boundary |
| 2. Configure credentials | Managed secrets and connectors | Provider keys, OAuth installs, MCP/tool access |
| 3. Create runtime profile | Agent runtime profile | Default harness, tools, non-secret env, policy |
| 4. Create primary device | Persistent sandbox or computer | Shared execution workspace |
| 5. Dispatch prompt | Agent run | One task sent into the chosen device |
| 6. Stream progress | Events, stdout, screenshots, previews | User-visible activity feed |
| 7. Export output | Sandbox file export | Downloadable PDFs, HTML, zips, screenshots, app folders |
| 8. Snapshot state | Sandbox snapshot or computer persistence | Resume without losing files/dependencies |
| 9. Publish | MIOSA Deploy or Docker Host | Stable customer-facing URL |
| 10. Scale | Queues, pools, groups, quotas | Many logical agents sharing controlled runtime capacity |

The important rule is that agent identity, runtime profile, device, credentials,
and artifacts are separate records. That separation is what lets you swap OSA
for Claude Code, move a task from sandbox to computer, or give one workspace a
different provider key without rewriting the product.

  Device-->>MIOSA: stdout, files, previews, screenshots
  App->>MIOSA: create export for deliverables

  App-->>User: progress, preview, download, approval

This is the smallest working version of a Polsia-style operator, a
Cofounder-style department agent, or a Nebula-style virtual device.

---

## Backend module shape

Keep these modules separate in your product backend. Combining them too early is
what makes agent products hard to debug.

```typescript
type AgentRuntime =
  | "osa"
  | "codex"
  | "claude-code"
  | "pi"
  | "hermes"
  | "gemini-cli"
  | "opencode"
  | "custom";

type AgentDevice =
  | { type: "sandbox"; id: string; cwd: "/workspace" | string }
  | { type: "computer"; id: string }
  | { type: "local"; id: string };

type AgentRunRequest = {
  workspaceId: string;
  agentId: string;
  runtime: AgentRuntime;
  device: AgentDevice;
  prompt: string;
  connectors: string[];
  approvalPolicy: "auto" | "confirm-risky" | "manual";
};
```

| Module | Interface | Implementation hidden behind it |
|---|---|---|
| Orchestrator | `dispatch(runRequest)` | Selects runtime, device, queue, retry policy, approvals |
| Runtime adapter | `start(prompt)`, `send(task)`, `stop()` | OSA, Codex, Claude Code, Pi, Hermes, or custom harness |
| Device adapter | `exec`, `writeFile`, `readFile`, `preview`, `snapshot` | MIOSA sandbox, computer, local device |
| Connector broker | `getToken(connector, subject, scopes)` | Provider auth, refresh, egress restrictions, audit |
| Event stream | `subscribe(runId)` | Tool calls, stdout, file writes, screenshots, artifacts, approvals |
| Artifact store | `putArtifact`, `versionArtifact` | PDFs, DOCX, images, zips, screenshots, generated apps |
| Deployment bridge | `publish(version)` | MIOSA Deploy, Docker Host, domains, rollback |

The frontend should never special-case every runtime. It should render the same
event contract regardless of whether the backend used OSA, Codex, Claude Code,
Pi, Hermes, or a customer-owned harness.

## Product mapping

### Build your own Polsia-style operator

Use this when the product promise is: "Describe the business. Agents keep
building, researching, selling, and improving it."

Use this MIOSA shape:

| Layer | MIOSA choice |
|---|---|
| Default device | Persistent sandbox |
| Browser work | Computer when a real browser or dashboard login is needed |
| Long-running work | Scheduled jobs that resume the persistent sandbox |
| Deliverables | Artifacts, previews, deployment URLs, reports |
| Production apps | MIOSA Deploy or Docker Host |
| Credentials | Managed connectors and scoped runtime tokens |
| UI | Task stream, plan, files, artifacts, preview, approvals |

Example task flow:

```text
User: Build a landing page and start outbound research.
Orchestrator:
  1. Resume the company workspace sandbox.
  2. Agent writes Next.js files in /workspace.
  3. Agent starts preview on port 3000.
  4. Computer agent opens the preview and captures screenshots.
  5. Research agent writes lead notes and campaign copy.
  6. User approves publish.
  7. Deploy agent publishes the app and stores the URL.
```

### Build your own Cofounder / Co-Founder AI-style company OS

Use this when the product promise is: "Run company departments with specialized
agents and human approval."

Start with this agent roster:

| Department agent | Device and tools |
|---|---|
| Engineering | Sandbox files, exec, previews, deploy |
| Design | Refero managed connector, browser screenshots, artifacts |
| Marketing | Web research, files, connected email/CRM tools |
| Sales | Browser/computer, CRM connector, approval before outbound |
| Finance | Connected accounting or spreadsheet tools, strict approval |
| Support | Browser/computer, helpdesk connector, memory, approvals |
| Operations | Jobs, schedules, reports, audit log |

Human approval belongs at the orchestrator layer for:

- publish production app
- send external messages
- buy domains or spend credits
- create high-cost child devices
- delete data, snapshots, deployments, or customer files
- use admin-level credentials

### Build your own Nebula-style virtual device

Use this when the product promise is: "Agents and humans share a persistent
workspace with files, code, browser, jobs, and connected apps."

Use this MIOSA device model:

| Nebula-style concept | MIOSA implementation |
|---|---|
| Virtual device | Persistent sandbox or computer |
| Local device | Paired customer-owned device |
| Files between sessions | Sandbox `/workspace`, snapshots, computer storage |
| Code execution | Sandbox exec and streaming output |
| Browser | Computer browser automation and screenshots |
| Live server | Sandbox preview URL |
| Jobs | Scheduled orchestrator tasks that resume the device |
| Shared across members | Workspace-scoped device policy and audit log |
| Miniapps | Generated apps published from sandbox to MIOSA Deploy or Docker Host |

The key design decision is the **primary device policy**. Each workspace should
know which sandbox, computer, or local device agents reach for by default.

### Build Heuresis-style encoded workspaces

Use this when the product promise is: "Turn a company's operating knowledge into
a folder that any agent runtime can execute."

Use this workspace folder contract:

```text
/workspace
  SYSTEM.md
  company.yaml
  agents/
    founder.md
    engineering.md
    marketing.md
    sales.md
    support.md
  skills/
    write-proposal/
      SKILL.md
      references/
    qualify-lead/
      SKILL.md
    build-landing-page/
      SKILL.md
  runbooks/
  artifacts/
  receipts/
```

| Layer | Purpose |
|---|---|
| `SYSTEM.md` | Boot file read by the selected agent runtime |
| `company.yaml` | Business facts, offers, ICP, pricing, brand, constraints |
| `agents/` | One file per role: scope, authority, standards, escalation path |
| `skills/` | Reusable capabilities that produce named assets |
| `runbooks/` | Repeatable operating procedures |
| `artifacts/` | Generated files users can inspect and download |
| `receipts/` | Decisions, outputs, approvals, and audit trail |

MIOSA is where this workspace can actually run. The encoded company lives in a
persistent sandbox. The selected runtime, such as OSA, Codex, Claude Code,
Gemini CLI, OpenCode, Cursor, Aider, Windsurf, OpenClaw, Qwen Code, Kimi Code,
or a custom harness, reads the workspace and executes inside `/workspace`.

This gives customers a portable company operating system while MIOSA still owns
the secure execution, persistence, events, quotas, connectors, and deployment
path.

---

## Implementation path

### 1. Choose the runtime shape

Do not hard-code one agent runtime into the platform. Make runtime a setting on
the agent or workspace.

| Runtime option | Best use |
|---|---|
| OSA | MIOSA-native agents and platform operations |
| Codex | Repo work, codebase edits, terminal-driven engineering |
| Claude Code | Agentic coding with tool use and MCP |
| Gemini CLI | Alternate coding and research loop |
| OpenCode, Cursor, Aider, Windsurf | User-selected coding harnesses |
| OpenClaw | Multi-agent orchestration brain paired with coding tools |
| Qwen Code, Kimi Code | Model/vendor-specific code agents |
| Custom | Your own harness, prompt format, queue, or model router |

The runtime should receive the same workspace contract: scoped MIOSA token,
assigned device, allowed connectors, and `/workspace` files.

### 2. Dispatch prompts into the device

The product must be able to send a prompt into the assigned runtime and keep the
agent working there. This is the core workflow.

```text
prompt
  -> route to agent runtime
  -> run inside assigned sandbox/computer/local device
  -> stream events back to product UI
  -> persist files, artifacts, screenshots, previews, and deployment records
```

Use a sandbox prompt when the agent should code, generate artifacts, or run
commands inside `/workspace`:

```bash
miosa prompt --sandbox <sandbox-id> \
  --harness claude-code \
  --json \
  "Build the landing page, run tests, start the preview, and leave the files in /workspace"
```

Use a computer agent prompt when the task needs a desktop or browser:

```bash
miosa prompt --computer <computer-id> \
  --harness claude-code \
  "Open the preview, test signup, capture screenshots, and report visual issues"
```

Send follow-up work into the same running computer-agent session:

```bash
miosa run steer \
  "Re-check the mobile nav after the sandbox agent patches it" \
  --computer <computer-id>
```

In a product backend, model this as one dispatch contract:

```typescript
type DevicePromptDispatch = {
  deviceType: "sandbox" | "computer" | "local";
  deviceId: string;
  runtime: "osa" | "codex" | "claude-code" | "gemini-cli" | "opencode" | "custom";
  prompt: string;
  cwd?: string;
  connectors?: string[];
  approvalPolicy?: "auto" | "confirm-risky" | "manual";
};
```

The UI should not care whether the prompt ran through OSA, Codex, Claude Code,
Hermes, OpenCode, or a custom harness. It should display the same run stream:
tool calls, command output, file writes, screenshots, artifacts, approvals, and
final URLs.

Prompt dispatch is available through `miosa prompt`, with `--sandbox` or
`--computer` for MIOSA-managed devices. For customer-owned OpenComputers hosts,
dispatch through `miosa api POST /opencomputers/hosts/<id>/agent/dispatch`.
Computer session APIs remain the right fit for long-running browser or desktop
conversations. Keep your product-level run model stable so every target can
share one UI.

### 3. Create or resume the workspace runtime

Use a persistent sandbox for code and files. Use a computer only when the task
requires a real browser, desktop, or screenshot loop.

```bash
miosa create customer-workspace \
  --template nextjs \
  --ttl 1h \
  --wait \
  --json
```

Then run work inside the sandbox:

```bash
miosa exec <sandbox-id> -- sh -lc "cd /workspace && npm install"
miosa exec <sandbox-id> -- sh -lc "cd /workspace && npm run build"
```

### 4. Make the agent write inside the device

The agent should edit files in `/workspace`, not build everything locally and
upload a finished repo at the end.

```text
bad:
  local agent builds repo on laptop
  upload after the fact
  remote sandbox only previews the result

good:
  agent writes files into sandbox
  sandbox installs dependencies
  sandbox runs tests/builds
  sandbox serves preview
  user sees events and artifacts as work happens
```

### 5. Stream progress into the product UI

Show users the work surface:

- plan created
- device created or resumed
- file written
- command started
- stdout/stderr chunk
- preview ready
- screenshot captured
- artifact generated
- approval required
- deployment ready

This is the difference between "the agent disappeared" and "the agent is
working in a real machine."

### 6. Attach connectors and secrets safely

Use managed connectors, scoped tokens, and runtime variables. Do not paste
provider keys into chat.

```text
Tenant key
  -> stays server-side
  -> mints scoped runtime token
  -> sandbox receives only the scoped token
  -> managed provider token is brokered only to the allowed provider endpoint
```

This is how a platform can provide a managed design-research connector while
still preventing arbitrary token exfiltration.

### 7. Save checkpoints and publish

Use snapshots and versioned deployments:

```text
checkpoint after dependencies install
checkpoint after first working preview
checkpoint before risky refactor
publish after tests and browser QA
rollback through deployment versions
```

For many small customer apps in one workspace, publish to
[Docker Host](/docs/docker-host/docker-deploy/). For normal production apps,
publish through MIOSA Deploy.

---

## What your frontend should show

| Surface | Purpose |
|---|---|
| Chat or task stream | User request, agent status, tool calls, command output |
| Device panel | Sandbox preview, computer desktop, logs, screenshots |
| Files panel | Workspace files, diffs, generated code, editable artifacts |
| Artifacts panel | PDFs, DOCX, images, ZIPs, screenshots, downloads |
| Approvals panel | Risky actions waiting for human confirmation |
| Jobs panel | Scheduled and background work |
| Deployment panel | Public URL, versions, rollback, domains |
| Usage panel | Credits, runtime minutes, sandbox/computer cost |

This is how to make MIOSA feel like an agent workspace, not just an API.

---

## Architecture rules

1. **Do not merge sandboxes and computers into one vague concept.** Sandboxes
   are for headless code, files, previews, and artifacts. Computers are for GUI
   and browser automation.
2. **Make persistence the default for agent work.** Idle compute can stop, but
   the workspace state should survive through snapshots or persistent storage.
3. **Use scoped runtime credentials.** Tenant admin keys stay server-side.
4. **Treat the orchestrator as your product.** MIOSA executes; your product
   decides roles, prompts, permissions, retries, approvals, and UI.
5. **Expose run events.** Users need to see code, commands, files, previews,
   artifacts, screenshots, and deploys as they happen.
6. **Dispatch prompts into assigned devices.** A user prompt should become a
   sandbox/computer/local-device run, not a detached local-only script.
7. **Separate development from hosting.** Agents build in sandboxes and
   computers. Finished apps run on deployments or Docker Host.
8. **Keep runtimes replaceable.** A workspace should be executable by OSA,
   Codex, Claude Code, OpenCode, Aider, OpenClaw, or a custom runtime without
   rewriting the customer's company knowledge.

# Configure an agent

URL: https://miosa.ai/docs/guides/configure-agent
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/configure-agent
Source: src/routes/docs/guides/configure-agent/+page.md
Description: Configure an agent's identity, instructions, model, devices, tools, memory, connected accounts, triggers, and approval policy.

# Configure an agent

An agent is a named worker with instructions, tools, devices, memory, connected
accounts, and approval rules. The goal is to make the agent predictable enough
to trust, but capable enough to do real work inside MIOSA sandboxes and
computers.

---

## Configuration checklist

| Setting | Why it matters |
|---|---|
| Name and description | Helps users and orchestrators route work to the right agent |
| Visibility | Private, workspace, or platform-managed |
| Instructions | Role, rules, output style, safety limits, and domain context |
| Model or runtime | Which model, harness, or custom runtime powers the loop |
| Default device | Where work happens by default: sandbox, computer, or local device |
| Tools | Files, exec, browser, artifacts, deployments, app actions |
| Connected accounts | OAuth grants, managed connectors, API keys, scoped variables |
| Memory | Durable facts the agent can reuse across threads or jobs |
| Triggers | Schedules, webhooks, app events, or user actions |
| Approval policy | Actions that require human confirmation |
| Quotas | Limits for spend, child devices, runtime duration, and concurrency |

---

## Identity

Use a focused name and description.

Good:

```text
Name: Landing Page Builder
Description: Builds, previews, and publishes branded Next.js landing pages.
```

Weak:

```text
Name: Helper
Description: Does stuff.
```

Agents are easier to delegate to when their job is specific.

---

## Visibility

| Mode | Who can use it | Best for |
|---|---|---|
| Private | The creator only | Personal experiments, sensitive research |
| Workspace | Members with access | Shared operators, support, marketing, development |
| Platform-managed | Controlled by your product | Built-in agents inside a white-label SaaS |

Workspace agents should never silently inherit every personal connection in the
workspace. Attach only the accounts and tools they need.

---

## Instructions

Instructions should include:

- the agent's role
- the expected output
- where work must happen
- what tools it may use
- what requires approval
- what counts as done

Example:

```text
You are a Next.js build agent.
Work only inside the assigned MIOSA sandbox at /workspace.
Write files directly into the sandbox.
Run npm install, npm run lint, and npm run build before returning.
Expose port 3000 for preview.
Create artifacts for screenshots and generated reports.
Ask for approval before publishing or creating extra child sandboxes.
```

If the agent should code inside a sandbox, say that directly. This prevents the
bad pattern where an agent builds locally and then tries to upload a finished
repo after the fact.

---

## Model and runtime

MIOSA can support several runtime shapes:

| Runtime | Use it for |
|---|---|
| OSA | MIOSA-native agent/runtime operations |
| Codex | Code generation and repository maintenance workflows |
| Claude Code | Agentic coding loops with tools and MCP |
| Pi | Compatible harness-based agent execution |
| Hermes | Custom or vendor-provided agent runtime |
| Custom | Bring your own loop, queue, prompt format, or model provider |

The runtime should be a configuration value, not hard-coded into product logic.
Your product can choose the default runtime per agent type and still allow
advanced users to supply custom runtimes later.

### Runtime profiles

For white-label products, configure default runtimes at the tenant or workspace
level instead of repeating the same connector and env setup for every sandbox.

```bash
miosa api POST /agent-runtime-profiles -d '{
  "name": "Default app builder",
  "runtime": "claude-code",
  "tools": ["files", "exec", "previews", "artifacts"],
  "connectors": ["refero/design-research", "anthropic/workspace-claude"],
  "policy": {"approval": "confirm-risky", "max_child_sandboxes": 5},
  "is_default": true
}'
```

```typescript
await miosa.agentRuntimeProfiles.create({
  name: "Default app builder",
  runtime: "claude-code",
  tools: ["files", "exec", "previews", "artifacts"],
  connectors: ["refero/design-research", "anthropic/workspace-claude"],
  policy: { approval: "confirm-risky", max_child_sandboxes: 5 },
  isDefault: true,
})
```

```python
client.agent_runtime_profiles.create(
    name="Default app builder",
    runtime="claude-code",
    tools=["files", "exec", "previews", "artifacts"],
    connectors=["refero/design-research", "anthropic/workspace-claude"],
    policy={"approval": "confirm-risky", "max_child_sandboxes": 5},
    isDefault=True,
)
```

Use profiles for defaults. Use `miosa prompt` or the Agent Runs API for
individual task dispatch.

When a default profile exists, every new sandbox or cloud computer in that
tenant/workspace gets the profile automatically unless the caller opts out.
MIOSA applies the profile before the runtime is inserted:

| Profile field | Sandbox behavior | Computer behavior |
|---|---|---|
| `runtime` | Stored in sandbox metadata so orchestrators know which agent harness to start | Stored in computer settings for orchestration and dispatch |
| `tools` | Stored in metadata as the expected tool bundle | Stored in settings as the expected tool bundle |
| `env` | Merged into sandbox env at boot; request-level env wins | Encrypted in the computer env store and synced after OSA is healthy |
| `connectors` | Bound through MIOSA egress as opaque placeholder tokens | Bound through MIOSA egress as opaque placeholder tokens |
| `policy` | Stored in metadata for approval, child-device, and quota decisions | Stored in settings for approval, child-device, and quota decisions |

```bash
# Uses the workspace or tenant default profile automatically.
miosa create builder --template nextjs --ttl 1h --wait

# Force a specific profile for this sandbox (API):
miosa api POST /sandboxes -d '{
  "name": "builder",
  "template": "nextjs",
  "agent_runtime_profile_id": "9f4b3d8e-0000-0000-0000-000000000000"
}'

# Create a browser/desktop computer with the workspace default profile.
miosa computer create browser-worker
```

```typescript
const sandbox = await miosa.sandboxes.create({
  templateId: "nextjs",
  agentRuntimeProfileId: "9f4b3d8e-0000-0000-0000-000000000000",
})

const computer = await miosa.computers.create({
  name: "browser-worker",
  agentRuntimeProfileId: "9f4b3d8e-0000-0000-0000-000000000000",
})
```

```python
sandbox = client.sandboxes.create(
    template_id="nextjs",
    agent_runtime_profile_id="9f4b3d8e-0000-0000-0000-000000000000",
)

computer = client.computers.create(
    name="browser-worker",
    agent_runtime_profile_id="9f4b3d8e-0000-0000-0000-000000000000",
)
```

Connector secrets are not copied into metadata or returned to the agent. The
runtime sees env vars such as `REFERO_MCP_TOKEN` or `ANTHROPIC_API_KEY`, but
those values are MIOSA egress placeholders (`miosa-tok-*`). The proxy swaps the
placeholder for the provider credential only when the request is allowed.

---

## Default device

Every agent should have a default device policy.

| Policy | Behavior |
|---|---|
| Sandbox-first | Create or resume a sandbox for code, files, commands, previews, and artifacts |
| Computer-first | Use a persistent desktop/browser computer for GUI and web tasks |
| Local-first | Use the paired user machine when local files or private network access is needed |
| Orchestrator | Start in one root device and launch child devices for specialized work |

For app builders, sandbox-first should be the default. For browser and RPA
agents, computer-first is usually correct.

---

## Tools

Attach only the toolkits the agent needs.

Common bundles:

| Bundle | Includes |
|---|---|
| Build app | Files, exec, live preview, snapshots, artifacts, publish |
| Browser QA | Browser, screenshots, clicks, form fill, preview access |
| Research | Web search, page extraction, Refero design research, note files |
| Artifact factory | Files, exec, media conversion, artifacts, version history |
| Integrations | Connected accounts, webhooks, app actions |
| Operator | Computer, browser, terminal, long-running jobs |

---

## Accounts and variables

Use account connections and variables instead of chat-pasted secrets.

| Type | Example | How it is exposed |
|---|---|---|
| OAuth account | GitHub, Google, Slack | Short-lived token or egress-brokered placeholder |
| API key | Anthropic, OpenAI, Stripe | Scoped env var |
| Managed connector | Refero design research | MIOSA-owned token, brokered to provider only |
| Tenant variable | `NEXT_PUBLIC_BRAND_NAME` | Plain env var |
| Runtime token | `MIOSA_API_KEY` | Scoped token for one workspace, user, project, or run |

Never paste a secret into an agent conversation. Store it through the dashboard,
API, CLI, or connector flow.

---

## Memory

Memory is durable context the agent can reuse. Keep it scoped.

Good memories:

- brand colors
- project routes
- client preferences
- deployment URLs
- app architecture notes
- recurring task rules

Avoid saving:

- raw secrets
- one-time OTPs
- irrelevant chat history
- stale debugging guesses

Memory should be editable and revocable by workspace owners.

---

## Triggers and jobs

Agents can run manually or automatically.

| Trigger | Example |
|---|---|
| Manual | User asks the agent to build a landing page |
| Schedule | Run a daily competitor scrape |
| Webhook | New GitHub issue creates a triage task |
| App event | New CRM lead generates a proposal |
| Runtime event | Failed deploy creates a fix task |

Triggered agents should write run records, stream events, and respect quotas.

---

## Approval policy

Require approval for risky actions:

- publishing to production
- creating extra child devices above a threshold
- sending messages externally
- writing to connected apps
- spending credits above a configured budget
- deleting files, snapshots, deployments, or data
- using high-privilege credentials

Routine reads, file writes inside the assigned workspace, tests, and preview
starts can usually be automatic.

# Connect agent accounts (keys and subscriptions)

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/connect-agent-accounts
Source: src/routes/docs/guides/connect-agent-accounts/+page.md
Description: Connect a model key, a Claude or ChatGPT plan, or a tool-server key to your workspace, or to one of your end users, from your own code. No console visit needed.

# Connect agent accounts (keys and subscriptions)

An agent run thinks with an account that belongs to its owner.
MIOSA never powers your agents with its own model keys.
So before a run can start, a model provider has to be connected: an API key, or a subscription plan such as Claude or ChatGPT.

You can do that in the console.
You can also do it from your own code, for your own workspace or for each of your end users.
That second case is what a platform needs: your customer connects their own Claude plan inside your product, and every run on their machines uses it.

This guide covers both.

## What you can connect

| Connection | What it is | How you connect it | Name in the SDK |
|---|---|---|---|
| Claude plan | A Claude Pro or Max subscription. | Sign-in, the user pastes a code back. | `claude` |
| ChatGPT plan | A ChatGPT Plus, Pro or Team subscription (Codex). | Sign-in, the user enters a code. | `chatgpt` |
| Kimi plan | A Kimi Code subscription. | Sign-in, the user enters a code. | `kimi` |
| Mistral Vibe plan | A Mistral Vibe subscription. | Sign-in in the browser. | `mistral` |
| Anthropic key | An Anthropic API key. | Set it. | `anthropic` |
| OpenAI key | An OpenAI API key. | Set it. | `openai` |
| OpenRouter key | An OpenRouter API key. | Set it. | `openrouter` |
| Other keys | DeepSeek, LLM Gateway, Moonshot, Mistral, Amazon Bedrock. | Set it. | `deepseek`, `llmgateway`, `moonshot`, `mistral`, `bedrock` |
| Tool-server keys | The key a tool server needs: Apify, Refero, any MCP server. | Set it. | `toolKeys` |

A key never leaves the platform.
Every read returns a status, a redacted preview such as `sk-ant...1234`, and for a plan the account email and plan name.
Never the secret.

One connected plan can power several harnesses where the vendor supports it.
A ChatGPT plan powers Codex and OpenCode, for example.
Connect it once, and any run on a compatible harness picks it up.
See [which harness uses which connection](#which-harness-uses-which-connection).

## Who the connection belongs to

Every call takes the same two optional identifiers.

| You pass | The connection belongs to | A run uses it |
|---|---|---|
| Nothing | Your organization. | In every workspace, unless a narrower one exists. |
| `workspaceId` | One workspace. | For runs in that workspace. |
| `externalUserId` | One of your end users: your own id for them. | For runs on that end user's machines, before the workspace's. |

A run looks for the account in this order, and stops at the first one it finds:

1. The end user's own connection.
2. The workspace's connection.
3. The organization's connection.

The end user is the one on the machine the run uses.
You tag a machine with `externalUserId` when you create it, the same id you use everywhere else in your platform ([Ownership and attribution](/docs/platform/attribution/)).

Writes and deletes always touch exactly the scope you name.
Setting a key for one end user never changes the workspace's key, and removing it falls back to the workspace's.
An end user's connection is never visible to another end user, to the workspace, or to another organization.

## Your own workspace

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

// An API key
await miosa.connections.setKey({
  provider: "anthropic",
  key: process.env.ANTHROPIC_API_KEY!,
  workspaceId,
})

// Check that it works
const check = await miosa.connections.test({ provider: "anthropic", workspaceId })
console.log(check.ok, check.httpStatus) // true 200
```

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

# An API key
miosa.connections.set_key(
    "anthropic",
    key=os.environ["ANTHROPIC_API_KEY"],
    workspace_id=workspace_id,
)

# Check that it works
check = miosa.connections.test("anthropic", workspace_id=workspace_id)
print(check["ok"], check["http_status"])  # True 200
```

```bash
# The key comes from standard input, never from an argument
miosa connections add models anthropic --workspace-id "$WORKSPACE_ID" --key-stdin <<< "$ANTHROPIC_API_KEY"

miosa connections test models anthropic --workspace-id "$WORKSPACE_ID"
```

Setting a key again replaces it.
That is how you rotate one.

## Your end users

Pass `externalUserId` and the connection is theirs.

### An API key

```typescript
await miosa.connections.setKey({
  provider: "openrouter",
  key: userSuppliedKey,
  externalUserId: "cus_123",
})
```

```python
miosa.connections.set_key(
    "openrouter",
    key=user_supplied_key,
    external_user_id="cus_123",
)
```

```bash
miosa connections add models openrouter --external-user cus_123 --key-stdin <<< "$USER_KEY"
```

An end user's key is for agents only.
It is never offered to the AI Gateway.

### A Claude plan or a ChatGPT plan

Connecting a plan is a sign-in the user completes in their own browser.
Your code starts it, shows the user a link, and waits.
The call returns at once with what to show.
Nothing is connected yet.

```typescript
const signin = await miosa.connections.connectSubscription({
  provider: "claude", // or "chatgpt", "kimi", "mistral"
  externalUserId: "cus_123",
})

// Show these in YOUR UI.
signin.verificationUrl // open this in the user's browser
signin.userCode        // ChatGPT and Kimi: the code they type there
signin.mode            // "paste_code" (Claude) or "device_code"
signin.expiresAt       // about 15 minutes

// Claude: the page shows a code after they approve. Your UI passes it back.
const connected = await signin.submitCode(codeTheyPasted)
console.log(connected.accountEmail, connected.accountPlan) // alice@example.com max

// ChatGPT, Kimi: they enter the code at the link. Wait until it lands.
const connected2 = await signin.wait({ onUpdate: (s) => console.log(s.status) })
```

```python
signin = miosa.connections.connect_subscription(
    "claude",  # or "chatgpt", "kimi", "mistral"
    external_user_id="cus_123",
)

# Show these in YOUR UI.
signin.verification_url  # open this in the user's browser
signin.user_code         # ChatGPT and Kimi: the code they type there
signin.mode              # "paste_code" (Claude) or "device_code"
signin.expires_at        # about 15 minutes

# Claude: the page shows a code after they approve. Your UI passes it back.
connected = signin.submit_code(code_they_pasted)
print(connected["account_email"], connected["account_plan"])  # alice@example.com max

# ChatGPT, Kimi: they enter the code at the link. Wait until it lands.
connected = signin.wait(on_update=lambda s: print(s["status"]))
```

```bash
# Prints the link and the code, then returns. Your UI shows them.
miosa connections add models claude --external-user cus_123 --no-wait --json

# Claude: hand over the pasted code.
miosa connections signin code SIGNIN_ID --external-user cus_123 --code-stdin <<< "$PASTED_CODE"

# ChatGPT, Kimi: wait for the user to enter the code.
miosa connections signin wait SIGNIN_ID --external-user cus_123
```

There are two shapes of sign-in:

| Mode | Plans | What the user does | What you do |
|---|---|---|---|
| `paste_code` | Claude | Approves at the link, then copies the code the page shows. | Pass that code to `submitCode`. |
| `device_code` | ChatGPT, Kimi | Opens the link and types `userCode`. | Call `wait()`, or `poll()` on a timer. |

`wait()` resolves when the plan is connected.
It rejects with `SubscriptionSignInError` if the sign-in failed, expired or was cancelled.
`poll()` never rejects for a failed sign-in: read its `status`.
`cancel()` ends the sign-in.

A wrong or expired pasted code is rejected with `SIGNIN_CODE_REJECTED` (422).
The sign-in stays open, so the user can paste again.

The sign-in link and the code carry no credentials.
The plan's tokens are stored encrypted on the platform, refreshed in the background, and never returned by any call.

Show the link to the person who owns the plan, in your own UI.
Do not open it for them from your server.
The sign-in is the user's consent to connect their plan.

### Check, list and remove

```typescript
// Is it connected, and where does it come from?
const claude = await miosa.connections.get({ provider: "claude", externalUserId: "cus_123" })
claude.connected    // true
claude.scope        // "external_user", or "workspace" when it is inherited
claude.inherited    // true when it comes from a wider scope
claude.preview      // "sk-ant...1234" for a key. Never the secret.

// Everything this end user has, with the workspace's inherited connections marked
const all = await miosa.connections.list({ externalUserId: "cus_123", workspaceId })

// Does it work?
await miosa.connections.test({ provider: "claude", externalUserId: "cus_123" })

// Disconnect only the end user's own. The workspace's, if any, is untouched.
await miosa.connections.delete({ provider: "claude", externalUserId: "cus_123" })
```

```python
claude = miosa.connections.get("claude", external_user_id="cus_123")
claude["connected"]   # True
claude["scope"]       # "external_user", or "workspace" when it is inherited
claude["inherited"]   # True when it comes from a wider scope

everything = miosa.connections.list(external_user_id="cus_123", workspace_id=workspace_id)

miosa.connections.test("claude", external_user_id="cus_123")
miosa.connections.delete("claude", external_user_id="cus_123")
```

```bash
miosa connections list --external-user cus_123 --workspace-id "$WORKSPACE_ID"
miosa connections test models claude --external-user cus_123
miosa connections rm models claude --external-user cus_123 --yes
```

`test` makes one cheap authenticated request to the provider, such as listing models.
For a plan it checks the stored state instead.
It answers `ok: true`, `ok: false` (the provider rejected the key) or `ok: null` (the provider did not answer, which is not the key's fault).
It never returns the key or the provider's response.

## Tool-server keys

A tool server is an MCP server your agents use: Apify, Refero, your own.
You define the server once, with its credential as a placeholder such as `{{secret:APIFY_TOKEN}}`.
Each end user then supplies their own value.
An agent run for that end user reaches the tool server with their key, and falls back to the workspace's.

```typescript
// Which keys do my tool servers need, and does this end user have them?
const keys = await miosa.connections.toolKeys.list({ workspaceId, externalUserId: "cus_123" })
// [{ name: "APIFY_TOKEN", connected: false, servers: [{ name: "Apify" }], ... }]

await miosa.connections.toolKeys.set({
  name: "APIFY_TOKEN",
  value: userApifyToken,
  workspaceId,
  externalUserId: "cus_123",
})

await miosa.connections.toolKeys.delete({ name: "APIFY_TOKEN", externalUserId: "cus_123" })
```

```python
keys = miosa.connections.tool_keys.list(workspace_id=workspace_id, external_user_id="cus_123")

miosa.connections.tool_keys.set(
    "APIFY_TOKEN",
    user_apify_token,
    workspace_id=workspace_id,
    external_user_id="cus_123",
)
miosa.connections.tool_keys.delete("APIFY_TOKEN", external_user_id="cus_123")
```

```bash
miosa connections tool-keys list --external-user cus_123
miosa connections tool-keys set APIFY_TOKEN --external-user cus_123 --key-stdin <<< "$USER_TOKEN"
miosa connections tool-keys rm APIFY_TOKEN --external-user cus_123 --yes
```

Only a name that a tool server references can be set.
Anything else is `UNKNOWN_TOOL_KEY` (404), so this is not a general-purpose secret store.

## Which harness uses which connection

A harness is the agent that runs on the machine: Claude Code, Codex, OpenCode and the others.
Each accepts a set of connections.

| Harness (`runner`) | Accepts |
|---|---|
| Claude Code (`claude-code`) | Claude plan, Anthropic key, OpenRouter key, DeepSeek key, Amazon Bedrock |
| Codex (`codex`) | ChatGPT plan, OpenAI key, DeepSeek key, Amazon Bedrock |
| OpenCode (`opencode`) | ChatGPT plan, Anthropic key, OpenAI key, OpenRouter key, LLM Gateway key, Mistral key, Mistral Vibe plan |
| Pi (`pi`) and Prime Agent (`prime`) | Claude plan, ChatGPT plan, Anthropic key, OpenAI key, OpenRouter key, LLM Gateway key, Mistral key, Mistral Vibe plan |
| Hermes Agent (`hermes`) | ChatGPT plan, Claude plan, Anthropic key, OpenAI key, OpenRouter key |
| Kimi Code (`kimi`) | Kimi plan, Moonshot key |
| Mistral Vibe (`mistral`) | Mistral Vibe plan, Mistral key |
| OSA (`osa`) | An Anthropic, OpenAI or OpenRouter key, or the model key you set in Agent Studio |

Two limits come from the vendors, not from MIOSA:

- OpenCode does not take a Claude plan. Anthropic prohibits it, and OpenCode removed the support.
- Hermes takes a Claude plan only on a Claude Max plan with extra usage purchased. A Pro plan is refused by Anthropic.

You connect once, and any run on a compatible harness picks the connection up.
You do not pick a connection per run.

To see what a given user can run right now:

```typescript
for (const harness of await miosa.harnesses.list({ externalUserId: "cus_123" })) {
  const usable = harness.connections.filter((c) => c.usable).map((c) => c.credential)
  console.log(harness.id, harness.ready ? "ready" : "no credential", usable)
}
// claude-code ready ["claude_subscription"]
// opencode    ready ["chatgpt_subscription"]
// pi          no credential []
```

```python
for harness in miosa.harnesses.list(external_user_id="cus_123"):
    usable = [c["credential"] for c in harness["connections"] if c["usable"]]
    print(harness["id"], "ready" if harness["ready"] else "no credential", usable)
```

```bash
miosa connections harnesses --external-user cus_123
```

The harness settings (which method is active, the default model) belong to you, the builder.
They are set per workspace and are the same for all of your end users.
The connections are theirs.
A key minted for an end user cannot change the harness settings.

## Choose which connection a harness uses

A harness that takes one method at a time (Claude Code, Codex) uses one connection.
A harness that takes several (OpenCode, pi, Prime Agent, Kimi Code, Mistral Vibe, Hermes Agent) uses the ones you enable.
These are the builder's settings, set per organization or per workspace.

```typescript
await miosa.agentSettings.updateHarness("claude-code", { authMethod: "claude_subscription", workspaceId })
await miosa.agentSettings.updateHarness("opencode", { enabledProviders: ["chatgpt_subscription", "openrouter"] })
```

```python
miosa.agent_settings.update_harness("claude-code", auth_method="claude_subscription", workspace_id=workspace_id)
miosa.agent_settings.update_harness("opencode", enabled_providers=["chatgpt_subscription", "openrouter"])
```

```bash
miosa connections use claude-code claude                    # the Claude plan
miosa connections use opencode chatgpt openrouter           # several
miosa connections use opencode --all                        # every connected one
miosa connections use codex --model gpt-6.1-sol --effort high
```

Then run on any harness, with the model you want:

```bash
miosa prompt --harness opencode --model gpt-6.1-sol --sandbox my-box "add a health check"
```

`miosa prompt --harness` takes every harness the platform lists, including ones added after your CLI was released.
`miosa connections harnesses opencode` lists that harness's models and which are available with what is connected.

## Build it into your product

A "Connect your Claude plan" button in your settings page is two requests to your backend.
The sign-in id travels through the browser, and your backend names the end user from its own session.

```typescript
// 1. Start. Send the browser only what it needs.
app.post("/api/connect/claude", async (req, res) => {
  const signin = await miosa.connections.connectSubscription({
    provider: "claude",
    externalUserId: req.user.id, // from YOUR session, never from the request body
  })
  res.json({ signinId: signin.id, url: signin.verificationUrl })
})

// 2. The user approves in a new tab and pastes the code into your page.
app.post("/api/connect/claude/code", async (req, res) => {
  const signin = miosa.connections.resumeSubscription({
    id: req.body.signinId,
    provider: "claude",
    externalUserId: req.user.id,
  })
  const status = await signin.submitCode(req.body.code)
  res.json({ connected: status.connected, email: status.accountEmail, plan: status.accountPlan })
})
```

`resumeSubscription` picks a sign-in up by its id.
Because it carries the end user, a sign-in id belonging to someone else is `NOT_FOUND`, even with your organization-wide key.

The worked example, with a runnable server, is in the SDK repository under `examples/connect-agent-accounts`.
It connects a Claude plan, a ChatGPT plan, a key and a tool-server key for two customers, and shows that one customer's connection never reaches the other's runs.

## Security

- **Server only.** Call these methods from your backend with your `msk_*` key.
  Never put that key in a browser.
- **Mint an end-user key** for anything that runs near your customer's code. A key minted with an `externalUserId` always acts as that end user.
  It cannot read or change the workspace's or the organization's connections (`403 SCOPE_FORBIDDEN`), cannot change harness settings, and cannot see another end user's sign-ins.
- **No secret is returned**, by any call. Keys and plan tokens are encrypted at rest, bound to the end user they belong to, and decrypted only to start a run.
- **Audit.** Every connect, replace, remove and use is written to the [audit log](/docs/security/audit-log/) with the end user's id and never the value.
- **Isolation.** A connection is checked against your organization on every read.
  An end user's id means nothing to another organization.
- **Scopes.** Reading needs `integrations:read` (plus `connections:read` for the connections list).
  Changing needs `integrations:write` (and `connections:write` for sign-ins).
- **Plans are the user's.** A plan connected for an end user is used only for runs on that end user's machines.
  It is never used to serve your other customers.
- **Rate limits** apply as everywhere ([Rate limits](/docs/rate-limits/)).

## Errors

| Code | Status | Meaning |
|---|---|---|
| `SCOPE_FORBIDDEN` | 403 | The key acts for one end user and asked for something wider. |
| `MISSING_EXTERNAL_USER_ID` | 422 | `scope: "external_user"` without an `externalUserId`. |
| `CONFLICTING_SCOPE` | 422 | `scope` does not agree with the identifiers. |
| `INVALID_EXTERNAL_USER_ID` | 422 | The id is longer than 255 characters or has control characters. |
| `USE_SIGNIN` | 422 | A plan cannot be set; connect it with `connectSubscription`. |
| `VALIDATION_FAILED` | 422 | A field is missing or wrong, for example an empty key. |
| `SIGNIN_CODE_REJECTED` | 422 | The pasted code was wrong or expired. Paste again. |
| `SIGNIN_PROVIDER_ERROR` | 502 | The provider's sign-in service did not answer. Start again. |
| `NOT_FOUND` | 404 | Nothing is connected at exactly that scope. |
| `UNKNOWN_CREDENTIAL` | 404 | Not a credential MIOSA knows. |
| `UNKNOWN_TOOL_KEY` | 404 | No tool server references that secret name. |
| `OWN_CREDENTIALS_REQUIRED` | 422 | A run was started with nothing connected for its harness. |

## The API underneath

The SDK and CLI are thin wrappers.
Every route accepts `workspace_id`, `external_user_id` and an optional `scope`.

| Route | Does |
|---|---|
| `GET /agents/credentials` | Every credential and its state at the scope. |
| `PUT /agents/credentials/{credential}` | Set or replace a key. |
| `DELETE /agents/credentials/{credential}` | Remove it at exactly the scope. |
| `POST /agents/credentials/{credential}/test` | Does it work? |
| `POST /agent-signins` | Start a plan sign-in. Returns the link and the code. |
| `GET /agent-signins/{id}` | Poll it. |
| `POST /agent-signins/{id}/code` | Hand over a pasted code. |
| `DELETE /agent-signins/{id}` | Cancel it. |
| `GET /agents/tool-keys` | The keys your tool servers need. |
| `PUT /agents/tool-keys/{name}` | Set one. |
| `DELETE /agents/tool-keys/{name}` | Remove one. |
| `GET /connections` | Models, apps and tool servers in one list. |
| `GET /agents/settings` | Harness readiness at the scope. |

# Build an internal Business OS for your team

Source: src/routes/docs/guides/internal-business-os/+page.md
Description: Build one internal platform where your team's agents, apps, data, and workflows live together, on MIOSA. Organization and workspaces, a machine per agent, connections, secrets, RBAC, audit, and internal deployments.

# Build an internal Business OS for your team

Some companies build an agent product to sell. Others build one platform for themselves, and run the company on it. This guide is the second one.

You are not launching this. It is not a product. It is the internal surface where your team's agents, apps, data, and workflows live together, and where every teammate and every agent gets a machine of their own.

If you are building a platform to sell to customers instead, read the [Platform builder guide](/docs/platform/overview/).

## Who it's for

- **A company with teams.** Ops, engineering, sales, support, finance. Each team gets a workspace. Each teammate and each agent gets a machine.
- **An agency running client work.** Each client becomes a workspace, so one platform holds every client's agents, apps, and spend without mixing them.

Both cases are the same shape: one organization, many workspaces, one machine per worker.

## What it is

One internal platform where:

- Every **agent** gets its own MIOSA computer or sandbox, with its own filesystem, network, and process tree.
- Every **team member** can reach those agents, their apps, and the shared data from one dashboard.
- The company's **tools** (GitHub, Slack, Linear, your model providers) are reachable through Connections (OAuth) and MIOSA-managed connectors, not copy-pasted API keys.
- **Secrets and environments** are managed centrally, so a new machine starts with exactly what it should have.
- Internal apps and **deployments** run behind the company domain.
- **Access, spend, and the audit trail** are governed in one place.

## Architecture

  O --> W2[Workspace: Engineering]

  W1 --> M1[Chief-of-staff agent<br/>own computer]

  M1 --> C1[Connections: GitHub, Slack, Linear, models]
  M2 --> C1
  M3 --> C1
  W1 --> S1[Secrets and environments]
  O --> L[Access control and audit log]

### Organization and workspaces

The organization is the company. It pays for everything and owns the balance. Workspaces group machines, deployments, and data per team, per client, or per function.

```bash
miosa workspace create Ops
miosa workspace create Engineering
miosa workspace list
miosa workspace inventory ops
```

Every resource can be created inside a workspace, so `miosa create ops-box --workspace ops` never mixes teams. Workspace-scoped usage and inventory are one command away:

```bash
miosa workspace stats ops
miosa workspace usage ops
```

### A machine per agent

An agent needs somewhere to write files, install packages, run commands, and preview an app. That is a sandbox. An agent that needs a visible desktop, a browser, or a GUI app needs a computer.

```bash
# A code agent's workspace
miosa create ops-agent --template miosa-sandbox --workspace ops --env prod --wait

# A persistent desktop for a browsing agent
miosa computer create chief-of-staff-desktop --env prod
```

Each gets its own filesystem, network, and process tree. Use [Agent device selection](/docs/guides/agent-device-selection/) to decide which one a given role needs.

### Connect the company's tools

Connections are what agents and machines use to reach the outside world: model providers, apps, and tool servers. MIOSA's own model keys never power your agents, so every run uses a connection of yours.

```bash
# Model provider with an API key (read from stdin, never from an argument)
miosa connections add models anthropic --key-stdin <<< "$ANTHROPIC_API_KEY"

# Or sign in with a subscription inside a named machine
miosa connections add models claude --sandbox ops-agent

# Company apps over OAuth
miosa connections add apps github
miosa connections add apps slack
miosa connections add apps linear

# A remote MCP tool server
miosa connections add tools --name docs --url https://mcp.internal.example.net/sse

miosa connections list --kind apps
```

For tools MIOSA already brokers, use [Managed connectors](/docs/guides/managed-connectors/) so no teammate has to hand over a vendor token.

### Secrets and environments

An environment is the template a new machine inherits: which repositories are cloned, which variables and secret files are injected, and which connections the machine may use. Every save mints a new immutable version, and a machine keeps the version it started with until you upgrade it.

```bash
miosa env new prod
miosa env set --env prod --from-file .env
miosa env file put --env prod backend/.env ./backend.env
miosa env repo add --env prod acme/internal-tools --branch main
miosa env default prod
```

Values are never passed as arguments. Set them interactively, pipe them on standard input, or load a `.env` file.

### Access control, SSO, and the audit log

Membership is per organization with four roles: owner, admin, member, and viewer. Only owners and admins can change membership.

```bash
miosa member add dana@example.net --role admin
miosa member role user_123 --role viewer
miosa workspace members ops
```

- **RBAC.** Give each team the role it needs, and scope API keys to a workspace and a preset so a CI job can only touch what it should: `miosa api-key create ci-deploy --preset ci --workspace-id <workspace-id>`.
- **Service accounts.** Give each internal integration its own identity instead of a shared key: `miosa service-account new ci-bot`, then `miosa service-account key new ci-bot`.
- **SSO/SAML.** Organization single sign-on (SAML) is available, including enforce-SSO for members. Membership is per organization with roles, and members sign in with a MIOSA account or a scoped key.
- **Audit log.** Every API action is recorded, newest first: `miosa audit`, `miosa audit --workspace-id <workspace-id>`, or `miosa audit --type sandbox.created`.

### Internal deployments behind the company domain

An app an agent builds is previewed from a sandbox port, then deployed durably behind the company domain.

```bash
miosa process start ops-agent -- python -m http.server 8080
miosa preview create ops-agent 8080 --name ops-dashboard
miosa preview share ops-agent <preview-id> --ttl 1h

miosa deploy list
miosa deploy domain-add ops-dashboard agents.example.net
miosa deploy rollback ops-dashboard --to <version-id>
```

The preview is how teammates review work in progress. The deployment is what they bookmark.

## Starting point

Two open-source repos you can start from today.


    The open-source business operating system: projects, CRM, docs, calendar, terminal, and AI agents in one app. Apache-2.0. This is the fastest way to get the platform shell your team will actually use.


    The open-source agent that runs inside those machines. Point it at a MIOSA computer or sandbox and it writes files, runs commands, and builds apps.


You do not have to use OSA. Any harness that can run inside a machine works: **Claude Code**, **Codex**, or a custom runtime. MIOSA's `miosa agent` commands wrap a harness, instructions, model, and the machine it runs on into one versioned definition.

## Step-by-step walkthrough

This is Acme Corp building its internal platform. The ops team gets a chief-of-staff agent, and everything lives behind `agents.example.net`.

### Step 1: create the organization surfaces

```bash
miosa workspace create Ops
miosa workspace create Engineering
miosa env new prod
miosa env default prod
```

Create one server API key for the platform's backend, and one scoped key per integration:

```bash
miosa api-key create acme-platform --preset cli
miosa api-key create ci-deploy --preset ci --workspace-id <ops-workspace-id>
```

### Step 2: give the ops team a machine

```bash
miosa create ops-agent --template miosa-sandbox --workspace ops --env prod --wait --ttl 8h
miosa computer create ops-desktop --env prod
miosa computer urls ops-desktop
```

### Step 3: connect the tools the team already uses

```bash
miosa connections add models claude --sandbox ops-agent
miosa connections add apps github
miosa connections add apps slack
miosa connections add apps linear
miosa connections add tools --name docs --url https://mcp.internal.example.net/sse
```

### Step 4: define the chief-of-staff agent

An agent is a saved, versioned definition: harness, model, instructions, the machine it runs on, and what it may do.

```bash
miosa agent new chief-of-staff \
  --harness claude-code \
  --model sonnet \
  --instructions-file agents/chief-of-staff.md \
  --workspace-id <ops-workspace-id>

miosa agent run chief-of-staff "Draft this week's ops summary from Slack and Linear" --sandbox ops-agent
```

Every run uses one of your model connections. Publish a new immutable version whenever the instructions change, so a run can always prove which version it used:

```bash
miosa agent publish chief-of-staff --instructions-file agents/chief-of-staff.md
```

### Step 5: ship an internal app

The agent writes an app inside its machine, you preview it, then deploy it behind the company domain.

```bash
miosa preview create ops-agent 8080 --name ops-dashboard
miosa preview share ops-agent <preview-id> --ttl 1h
miosa deploy domain-add ops-dashboard agents.example.net
```

### Step 6: add the other teams

Engineering gets a build sandbox, Sales gets a pipeline computer. Same pattern, different workspace:

```bash
miosa create build-agent --template nextjs --workspace engineering --env prod --wait
miosa computer create pipeline-desktop --env prod
miosa agent new builder --harness claude-code --workspace-id <engineering-workspace-id>
miosa agent run builder "Set up the release checklist repo" --sandbox build-agent
```

### Step 7: wire the same commands into the SDK or the API

The CLI is a thin client over the API. Anything your internal portal does can go through the SDK.

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

// One workspace per team
await miosa.workspaces.create({ name: "Ops", slug: "ops" })

// A machine for the agent, inside that workspace
const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceSlug: "ops",
})

// Dispatch a run onto that machine
const run = await miosa.agentRuns.run({
  prompt: "Draft this week's ops summary",
  targetKind: "sandbox",
  targetId: sandbox.id,
})

console.log(run.id)
```

```python

client = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])

client.workspaces.create(name="Ops", slug="ops")

sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    workspace_slug="ops",
)

run = client.agent_runs.run(
    prompt="Draft this week's ops summary",
    target_kind="sandbox",
    target_id=sandbox.id,
)

print(run["id"])
```

## Example scenarios

### Acme Corp: ops team with a chief-of-staff agent

Acme runs one organization. The `ops` workspace holds a persistent computer and a chief-of-staff agent. The agent reads Slack and Linear through Connections, drafts the weekly summary, and drops it in the shared docs app. When a teammate wants a new internal tool, the same agent builds it in its sandbox and deploys it to `agents.example.net`. Finance checks `miosa workspace usage ops` at the end of the period.

### Northwind Agency: per-client workspaces

Northwind is an agency running client work. Each client is a workspace: `northwind-agency` for the agency itself, plus one per client. Each client's agents and apps live inside their own workspace, so nothing crosses between clients, and the agency's dashboard reports usage per client. Branded previews and deployment domains come from the agency's own domain, `northwind.studio`.

## Security and governance checklist

**Identity and access**

- One organization, roles per member (`owner`, `admin`, `member`, `viewer`).
- A workspace per team or client, and the right role on each.
- One scoped API key per integration, bound to a workspace and a preset.
- A service account per automated integration, not a shared personal key.
- Organization SSO (SAML) is available, including enforce-SSO; treat MIOSA accounts like any other corporate identity until it is configured.

**Secrets**

- Keep secrets in environments, versioned and immutable, never in a repo.
- Put secret files in the environment so a machine receives them at start.
- Rotate keys on a schedule; rotate the platform key periodically.

**Runtime**

- One machine per agent, never shared across teams.
- Set TTLs and idle timeouts so idle machines pause instead of billing.
- Restrict outbound traffic with [Network policy](/docs/security/network/) and review the [egress audit](/docs/security/audit-log/).

**Governance**

- Review `miosa audit` regularly, and filter by workspace or event type.
- Cap per-member spend and concurrency with `miosa org caps`.
- Store `workspace_id` and `project_id` next to your own IDs so usage, audit, and billing reconcile.

## Next steps

# Managed connectors for sandbox agents

URL: https://miosa.ai/docs/guides/managed-connectors
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/managed-connectors
Source: src/routes/docs/guides/managed-connectors/+page.md
Description: Attach MIOSA-managed tools like Refero to sandbox or computer agents without client-supplied vendor tokens.

# Managed connectors for sandbox agents

MIOSA agents should build inside MIOSA sandboxes or computers. The local CLI or
MCP client should orchestrate the work; the sandbox/computer should be where the
agent writes files, installs packages, runs commands, previews apps, and
produces artifacts.

Managed connectors give those in-VM agents tools without asking every client to
bring vendor credentials.

## Connectors, egress, and MCP

These three surfaces work together, but they are not interchangeable:

| Surface | Owns | Example |
|---|---|---|
| Connector | Identity and credential grant for a provider or tool | `refero/design-research`, `anthropic/workspace-claude`, a tenant OAuth install |
| Egress | Network policy and token brokering from the sandbox/computer to approved endpoints | Swap `miosa-tok-*` only when calling `https://api.refero.design/mcp` |
| MCP | Tool protocol the agent runtime speaks inside the sandbox, computer, editor, or hosted endpoint | Claude Code calls a Refero MCP server or the MIOSA hosted MCP server |

A connector says **what account/tool is granted**. Egress says **where network
traffic may go and when placeholders can be exchanged**. MCP says **how an
agent discovers and invokes tools**. A product may use all three in one run:
attach a connector, enforce egress to the provider endpoint, and configure the
agent runtime to call that provider through MCP.

`refero/design-research` is MIOSA-managed. Tenants can attach it to a sandbox,
but MIOSA does not return the Refero token to clients.

## Default flow

Create a sandbox with enough time for active agent work:

```bash
miosa create builder \
  --template nextjs \
  --ttl 1h \
  --wait \
  --json
```

Attach Refero Design Research:

```bash
miosa connections add tools \
  --name refero-design-research \
  --url https://api.refero.design/mcp \
  --header-env Authorization=REFERO_MCP_TOKEN \
  --json
```

Run the agent inside `/workspace`:

```bash
miosa prompt --sandbox <sandbox-id> \
  --harness claude \
  --json \
  "Research product references, build the page, run tests, and leave files in /workspace"
```

For direct tool use, the same sandbox can be edited with file and command
commands:

```bash
miosa files cp ./page.jsx <sandbox-id>:/workspace/app/page.jsx --json
miosa exec <sandbox-id> --cwd /workspace --json -- npm run build
miosa wait <sandbox-id> --timeout 180s --json
```

## How the token works

The sandbox receives a brokered placeholder:

```bash
REFERO_MCP_TOKEN=miosa-tok-...
```

The real provider token stays encrypted in MIOSA-controlled infrastructure. The
egress proxy swaps the placeholder only for the provider endpoint it belongs to,
for Refero:

```text
https://api.refero.design/mcp
```

That means:

- clients do not paste the Refero token,
- the token is not shown by `miosa connections list`,
- `miosa connections test refero-design-research` does not return the token,
- sandbox code can still use normal environment-variable based MCP config.

## MCP config inside the sandbox

Use the brokered env var in the agent's MCP configuration:

```toml
[mcp_servers.refero]
enabled = true
url = "https://api.refero.design/mcp"

[mcp_servers.refero.http_headers]
Authorization = "Bearer ${REFERO_MCP_TOKEN}"
```

## Tenant-provided connectors

When MIOSA does not provide a connector, tenants can still bring their own:

```bash
printf '%s' "$ANTHROPIC_API_KEY" \
  | miosa connections add models anthropic \
      --label workspace-claude \
      --key-stdin \
      --json
```

## Which runtime should I use?


    Agent coding, generated files, tests, package installs, live preview, and publish prep.


    Persistent desktop or VM workflows, browser/GUI tasks, SSH, and long-running operator sessions.


    Durable app containers on the workspace Docker Host host after the sandbox-built app is ready.

# Runtime env for agent devices

URL: https://miosa.ai/docs/guides/runtime-env
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/guides/runtime-env
Source: src/routes/docs/guides/runtime-env/+page.md
Description: Define inherited environment variables for sandboxes, computers, and agent runtimes at tenant, workspace, or project scope.

# Runtime env for agent devices

Runtime env lets a platform owner define environment variables once and have
them inherited by sandboxes, computers, and agent runs. Use it for provider keys,
model configuration, MCP tokens, workspace defaults, and white-label customer
settings that should be available automatically when a device starts or runs a
command.

This is the foundation for products where users create many agent workspaces:
app builders, browser operators, 24/7 company agents, research agents, and
customer-specific automation fleets.

Runtime env values are encrypted at rest and are never returned as plaintext by
the API, CLI, or SDKs. Responses include metadata and a short preview only.

## Scope model

MIOSA resolves runtime env in this order:

| Precedence | Scope | Applies to |
|---:|---|---|
| 1 | Tenant | Every workspace, project, sandbox, computer, and agent under the tenant |
| 2 | Workspace | Every project, sandbox, computer, and agent in that workspace |
| 3 | Project | Sandboxes, computers, deployments, and agent runs attributed to that project |
| 4 | Resource | Per-sandbox or per-computer env set directly on the resource |
| 5 | Run | Env passed directly to a single exec or agent run |

More specific values override broader values with the same name. A project value
overrides a workspace value; a workspace value overrides a tenant value.

## Target model

Each runtime env var also has a target:

| Target | Use it when |
|---|---|
| `all` | The value is safe and useful for every runtime surface |
| `sandbox` | The value should only appear in sandbox exec/build/agent sessions |
| `computer` | The value should only appear in desktop computer commands and agents |
| `agent` | The value should be injected into prompt-driven agent runs on sandboxes or computers |

At the same scope, target-specific values override `all`.

## Common patterns


    Set `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, or product feature flags at
    workspace scope for one client workspace.


    Set `HIGGSFIELD_API_KEY` or image model keys at project scope for one app or customer workflow.


    Set `ANTHROPIC_MODEL`, `MIOSA_AGENT_CWD`, or MCP endpoint configuration for a class of agents.


    Set deployment, registry, package manager, or private API credentials for generated builds.


## CLI

Runtime Env has no dedicated `miosa` subcommand; drive it with `miosa api`
against the `/runtime-env` endpoint. Set a tenant-wide sandbox value:

```bash
miosa api POST /runtime-env -d '{
  "name": "ANTHROPIC_API_KEY",
  "value": "sk-ant-...",
  "scope": "tenant",
  "target": "sandbox"
}'
```

Set a workspace-wide computer value:

```bash
miosa api POST /runtime-env -d '{
  "name": "OPENAI_API_KEY",
  "value": "sk-...",
  "scope": "workspace",
  "workspace_id": "ws_123",
  "target": "computer"
}'
```

Set a project value for all runtime surfaces:

```bash
miosa api POST /runtime-env -d '{
  "name": "HIGGSFIELD_API_KEY",
  "value": "higgs_...",
  "scope": "project",
  "project_id": "prj_123",
  "target": "all"
}'
```

List, show and delete:

```bash
miosa api GET /runtime-env?scope=workspace&workspace_id=ws_123
miosa api GET /runtime-env/<env-id>
miosa api DELETE /runtime-env/<env-id>
```

Filter by target to see one surface's variables:

```bash
miosa api GET /runtime-env?target=sandbox
```

Run an agent with inherited `target=agent` env and download the file it creates:

```bash
miosa api POST /runtime-env -d '{
  "name": "ANTHROPIC_API_KEY",
  "value": "sk-ant-...",
  "scope": "project",
  "project_id": "prj_123",
  "target": "agent"
}'

miosa agent run my-agent \
  --sandbox sbx_123 \
  --no-follow

miosa run files <run-id> --json
miosa run download <run-id> <file-id> --output ./report.html
```

## SDKs

```ts

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

await miosa.runtimeEnv.set({
  scope: "workspace",
  workspaceId: "ws_123",
  target: "sandbox",
  name: "ANTHROPIC_API_KEY",
  value: process.env.ANTHROPIC_API_KEY!,
  metadata: { provider: "anthropic" },
});

const vars = await miosa.runtimeEnv.list({
  scope: "workspace",
  workspaceId: "ws_123",
  target: "sandbox",
});
```

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

client.runtime_env.set(
    scope="workspace",
    workspace_id="ws_123",
    target="sandbox",
    name="ANTHROPIC_API_KEY",
    value=os.environ["ANTHROPIC_API_KEY"],
    metadata={"provider": "anthropic"},
)

vars = client.runtime_env.list(
    scope="workspace",
    workspace_id="ws_123",
    target="sandbox",
)
```

## Verify inside a sandbox

Create a sandbox, wait for the VM session, then read the inherited value:

```bash
miosa create env-check \
  --template miosa-sandbox \
  --ttl 1h \
  --wait \
  --json

miosa exec env-check \
  --json \
  -- printf "$ANTHROPIC_API_KEY"
```

Use `--port` only when you also want app preview readiness:

```bash
miosa wait <sandbox-id> --timeout 180s --json
```

## Verify inside a computer

Use computers when the agent needs a desktop, browser session, GUI automation,
or long-running state:

```bash
miosa computer create browser-agent --json
miosa device exec <computer-id> --command 'printf "$OPENAI_API_KEY"' --json
```

## Verify inside an agent run

Agent runs are prompt-driven tasks dispatched to a sandbox or computer. They
inherit `target=agent` env, then apply any per-run `env` overrides. The run
record stores command metadata, status, output, events, and declared artifact
paths.

```ts
const run = await miosa.agentRuns.run({
  sandboxId: "sbx_123",
  provider: "claude-code",
  cwd: "/workspace",
  prompt: "Create /workspace/report.html with the final proposal.",
  metadata: {
    artifact_paths: ["/workspace/report.html"],
  },
});

const artifacts = await miosa.agentRuns.artifacts(run.id);
const html = await miosa.agentRuns.downloadArtifact(run.id, artifacts[0].id);
```

```python
run = client.agent_runs.run(
    sandbox_id="sbx_123",
    provider="claude-code",
    cwd="/workspace",
    prompt="Create /workspace/report.html with the final proposal.",
    metadata={"artifact_paths": ["/workspace/report.html"]},
)

artifacts = client.agent_runs.artifacts(run["id"])
html = client.agent_runs.download_artifact(run["id"], artifacts[0]["id"])
```

## Agent runtime profiles and connectors

Runtime env is one layer of the agent configuration stack:

| Layer | Purpose |
|---|---|
| Runtime env | Inherited env vars and provider keys by scope and target |
| Agent runtime profile | Runtime choice, non-secret defaults, tools, policy, connectors |
| Connector | Brokered provider identity or managed account |
| Egress | Network policy and brokered token exchange |
| Agent run | One prompt/task dispatched to a sandbox or computer |

Store provider keys in runtime env when the runtime expects a normal env var.
Use connectors when MIOSA should broker a provider grant or managed tool.

## Export generated work

When the agent creates files, download declared agent-run artifacts or export
raw sandbox paths instead of scraping terminal output:

```bash
miosa run files <run-id> --json
miosa run download <run-id> <file-id> --output ./report.pdf
```

```bash
miosa files cp <sandbox-id>:/workspace/out/report.pdf ./report.pdf --json

miosa files cp -r <sandbox-id>:/workspace/out ./customer-deliverables --json
```

For a new live Docker Host app, expose the development port and publish with an explicit production identity:

```bash
miosa wait <sandbox-id> --json
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --port 3000 \
  --type docker_deploy \
  --wait \
  --json
```

For later updates, publish to the existing deployment ID so the stable URL and release history remain attached to the same app:

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name <deployment> \
  --dir /workspace \
  --port 3000 \
  --type docker_deploy \
  --wait \
  --json
```

# Claude Code Skills for MIOSA

Skills extend Claude Code with MIOSA-specific knowledge. Install them once and Claude automatically loads the right one when you ask for cloud infrastructure  -  no manual prompting.

## What you get

| Skill | What it does |
|---|---|
| `miosa-mcp` | Universal entry point  -  explains the 145-tool surface and routes to specific skills |
| `miosa-sandbox` | Headless code-execution VMs (Python, Node, builds, CI) |
| `miosa-computer` | Desktop VMs (browser automation, GUI, computer-use) |
| `miosa-deploy` | Git-backed web app hosting (Next.js, Vite, Flask, Django) |
| `miosa-data` | Managed Postgres/MySQL/Redis, S3 storage, volumes, cron |

Each skill ships with an `examples.md` (or `reference.md`) bundled file Claude loads on demand. SKILL.md bodies stay under 100 lines  -  minimum context cost, maximum signal.

## Install

```bash
git clone https://github.com/Miosa-osa/miosa-skills.git
cp -r miosa-skills/* ~/.claude/skills/
```

Or per-project:

```bash
cp -r miosa-skills/* .claude/skills/
```

## Verify

Open Claude Code in any project and ask:

```
What skills are available?
```

You should see all 5 `miosa-*` skills listed.

## How they activate

You don't need to invoke them manually. Each skill declares trigger phrases in its `description` and `when_to_use` frontmatter. Say things like:

- "create a sandbox and run this" → `miosa-sandbox` loads
- "take a screenshot and click the login button" → `miosa-computer` loads
- "deploy this repo to production" → `miosa-deploy` loads
- "I need a Postgres database" → `miosa-data` loads

You can also invoke directly with `/miosa-sandbox`, `/miosa-computer`, etc.

## Structure (official Agent Skills spec)

```
~/.claude/skills/miosa-sandbox/
├── SKILL.md         # YAML frontmatter + tight overview (<100 lines)
└── examples.md      # Workflow patterns, loaded on demand
```

Each `SKILL.md` includes:

- `description`  -  what the skill does, when to use it
- `when_to_use`  -  trigger phrases for automatic activation
- `allowed-tools`  -  pre-approved MCP tools (no permission prompts)

Body covers: lifecycle, sizes, conventions, the core loop, errors. Detailed examples live in the sibling file so they don't bloat context until you need them.

## What's in each skill

### miosa-mcp
- Resource map (sandbox vs computer vs deployment vs database vs storage vs volume)
- Universal conventions (IDs, status polling, sizes, paths, timeouts)
- Decision tree pointing to the right resource skill
- `reference.md` with the full 145-tool catalog by category

### miosa-sandbox
- Core loop: `create_sandbox` → `exec` → `destroy_sandbox`
- Size guidance (small=4GB, medium for builds, etc.)
- Heredoc trick for multi-file projects
- `examples.md`: build-and-serve, data processing, snapshot reuse, PR testing, benchmarks

### miosa-computer
- Screenshot → identify → click/type → screenshot → verify loop
- Coordinate system (1024×768, absolute pixels)
- Mouse/keyboard tool table
- `examples.md`: browser automation, form filling, checkpoints, services, drag-drop, hotkeys

### miosa-deploy
- GitHub → deployment flow
- Sandbox promotion via `sandbox_deploy`
- Framework auto-detection table
- `examples.md`: Next.js+DB, preview branches, rollback, env updates

### miosa-data
- Database creation + credential wiring
- Storage buckets + presigned URLs (PUT and GET)
- Volume vs storage decision table
- Cron schedule reference
- `examples.md`: full-app patterns, backup pipelines, client-direct uploads

## Customizing

The skills are intentionally tight. To extend:

1. Add an `examples.md` entry under the skill that needs the pattern
2. Add `paths:` to a skill's frontmatter to restrict it to certain file types
3. Override `allowed-tools` if you want manual approval on certain tools

To override a skill's listing (e.g. hide one):

```json
// .claude/settings.local.json
{
  "skillOverrides": {
    "miosa-computer": "off"
  }
}
```

## Why skills instead of CLAUDE.md

CLAUDE.md content loads into context on every session. Skills load only when relevant. For a large, evolving tool catalog across many resource types, that's the difference between burning ~3,000 tokens per session vs ~200 tokens (just the descriptions).

## Updating

```bash
cd ~/.claude/skills
git -C miosa-skills pull
cp -r miosa-skills/* .
```

Claude Code watches the skills directory and picks up changes mid-session  -  no restart needed.

# AWS customer-cloud regions

URL: https://miosa.ai/docs/infrastructure/byoc/aws
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/infrastructure/byoc/aws
Source: src/routes/docs/infrastructure/byoc/aws/+page.md
Description: Architecture and readiness contract for running MIOSA worker capacity inside a customer AWS account.

The AWS path uses customer-reviewed Terraform or CloudFormation to create a private, scoped worker foundation.

Activation gated
Terraform and CloudFormation validated

## Packaged foundation

The current AWS packages define:

- A customer-specific external-ID trust boundary.
- A least-privilege worker instance profile.
- Private subnets across at least two Availability Zones.
- An egress-only security group with no inbound rules.
- Immutable launch-template versions.
- Encrypted root and XFS copy-on-write volumes.
- A fail-closed Auto Scaling lifecycle hook.
- A dedicated, versioned bootstrap secret per host attempt.
- Immutable runtime manifests with exact SHA-256 verification.

## Security architecture

Diagram:
flowchart TB
  MIOSA["MIOSA control plane"] -->|AssumeRole with external ID| Role["Customer control role"]
  Role --> ASG["Owned Auto Scaling resources"]
  ASG --> Host["Private worker host"]
  Host -->|Scoped role| Artifacts["Approved artifact source"]
  Host -->|One dedicated secret| Secret["Bootstrap acceptance bundle"]
  Host -->|Outbound TLS and WireGuard| MIOSA
  Host --> Guests["Firecracker workloads"]
  Guests --> COW["Encrypted XFS COW storage"]

Revoking the cross-account role is the customer control-plane kill switch.

The worker role cannot administer EC2, Auto Scaling, IAM, or unrelated storage.

Hosts receive no public IP and accept no inbound security-group traffic.

## Readiness is fail-closed

Terraform and CloudFormation completion do not make a worker schedulable.

The packaged fleet begins at zero capacity.

When activation is enabled, each launched host must remain behind an Auto Scaling lifecycle hook until MIOSA verifies:

1. The expected immutable image and runtime generation.
2. Encrypted root and copy-on-write device mappings.
3. Nested virtualization and `/dev/kvm`.
4. Snapshot restore support.
5. Outbound control-plane and WireGuard reachability.
6. A fresh authenticated host session.
7. One real guest boot smoke.
8. Scheduler capability advertisement.

Timeouts abandon the launch instead of admitting an ambiguous host.

## Current maturity

The Terraform, CloudFormation, bootstrap, runtime-artifact, and control-plane contracts are implemented and validated in repository CI.

General production activation remains gated because the capacity packages intentionally create zero active hosts and live provider mutation requires a certified AWS/KVM canary.

The current public contract is architecture and controlled onboarding preparation.
Production placement must remain disabled until the acceptance gate is certified and enabled for the organization.

## What customers will control

- AWS account and selected region.
- VPC, private subnets, routing, and endpoints.
- Customer IAM review and revocation.
- KMS and cloud storage choices.
- Provider quotas and provider billing.
- Terraform state or CloudFormation stack.
- Final placement enablement.

## Sandbox runtime boundary on customer hosts

MIOSA-managed sandboxes run on capacity operated by MIOSA.
AWS BYOC places eligible sandboxes on accepted hosts in a customer's AWS environment while retaining the public sandbox API and resource contract.

AWS BYOC sandbox capacity is a gated private preview.
Catalog entries and API access do not prove that a customer host has passed acceptance or that placement is enabled.

Each customer host runs the standalone `miosa_host` runtime.
Customer hosts do not run the control-plane compute service.
That service remains inside the MIOSA control plane, where it performs admission, policy evaluation, catalog resolution, scheduling, lifecycle coordination, and usage accounting.

The host initiates an outbound session to the MIOSA control plane.
The control plane can revoke that session and fence the host so a disconnected, replaced, or stale host process cannot continue receiving placement.
No inbound control-plane listener is required on the customer host.

The public sandbox API does not expose customer host IDs, provider instance fields, placement records, network addresses, credentials, or session fencing details.

### Certified artifacts

BYOC sandboxes boot only from immutable artifact generations certified for the selected public template.
Templates and sizes in `GET /api/v1/templates` identify customer-visible configuration, not mutable host paths or provider images.

A host must have the required certified generation and pass artifact integrity and runtime compatibility checks before it can be accepted for placement.
MIOSA does not silently substitute an uncertified local image when that generation is missing.

### Host acceptance before placement

Registering a host does not make it schedulable.
MIOSA must accept the host before any sandbox can be placed on it.

Acceptance verifies the conditions required by the preview environment, including:

- Compatible `miosa_host` and control-plane protocol versions.
- Required hardware virtualization and host capacity.
- Storage and network prerequisites.
- Availability and integrity of the certified artifact generation.
- A healthy outbound session with a current fencing generation.
- Runtime readiness checks required for sandbox execution.

Acceptance can be withdrawn when one of these conditions stops holding.
A withdrawn or fenced host receives no new placement until it passes acceptance again.

### Configuration vs request parameters

Environment configuration determines which accepted hosts, templates, resource contracts, policies, and limits are available to a tenant.
That configuration is established outside ordinary sandbox create requests.

Per-sandbox requests select only public workload behavior: `template_id`, `size`, `timeout_sec`, `idle_timeout_sec`, `always_on`, and `persistent`.

Use `GET /api/v1/templates` as the catalog source.
Select only a size listed for the chosen template as `fast_ready` or `cold_boot_only`, and use that template's `default_size` when no other supported size is requested.
`cold_boot_only` is valid but slower; `missing` is unavailable.
The default `small` resource contract is 2 vCPU, 4096 MiB RAM, and 10240 MiB disk when the selected template advertises it as ready.

### Responsibility boundary

| Area | Customer responsibility | MIOSA responsibility |
|---|---|---|
| AWS environment | Account ownership, host capacity, network egress, customer IAM, and customer-controlled infrastructure policy | Document required connectivity and reject environments that do not satisfy acceptance |
| Host operation | Keep the accepted host and its operating environment available and within the agreed configuration | Provide and coordinate `miosa_host`, session fencing, runtime compatibility checks, and acceptance state |
| Artifacts | Preserve the storage and access prerequisites needed by the accepted host | Publish immutable certified generations and prevent placement when the required generation is absent or invalid |
| Sandbox control | Choose public template, size, lifecycle, and persistence parameters | Resolve versioned resource contracts, enforce policy, schedule only onto accepted hosts, and coordinate lifecycle operations |
| Isolation and access | Control the customer AWS boundary and access to customer infrastructure | Enforce sandbox isolation and avoid exposing internal host or provider details through the public API |
| Usage records | Reconcile usage with customer infrastructure records when required | Report public usage measurements and preserve unavailable or stale measurement semantics |

### Availability and limits

BYOC does not imply a guaranteed sandbox count, launch rate, or geographic scale.
Actual availability is bounded by accepted customer capacity, certified artifact readiness, tenant policy, and current catalog state.
MIOSA will publish measured limits only after they have been validated for the applicable environment.

Managed and accepted BYOC sandboxes use the same customer-visible lifecycle operations, including extend, pause, resume, fork, usage, and destroy.
See [Sandboxes](/docs/develop/sandboxes/) for request examples and [Snapshots and persistence](/docs/develop/snapshots/) for lifecycle behavior.

# Google Cloud customer-cloud regions

URL: https://miosa.ai/docs/infrastructure/byoc/gcp
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/infrastructure/byoc/gcp
Source: src/routes/docs/infrastructure/byoc/gcp/+page.md
Description: Architecture and readiness contract for running MIOSA worker capacity inside a customer GCP project.

The Google Cloud path uses customer-owned Terraform to create a private worker foundation and reusable instance template.

Activation gated
Terraform foundation validated

## Packaged foundation

The current GCP package defines:

- A scoped worker service account.
- IAM bindings for approved artifacts, telemetry, and one bootstrap secret.
- A VPC, subnetwork, and firewall rules.
- A reusable Compute Engine instance template.
- Optional GCS artifact access.
- Immutable manifest and checksum inputs.
- A dedicated Secret Manager object for each provisioning attempt.
- Labels binding every resource to its MIOSA region and tenant.

The module does not create running instances by itself.

## Security architecture

Diagram:
flowchart TB
  Customer["Customer Terraform operator"] --> Foundation["VPC and instance template"]
  Foundation --> Host["Private worker host"]
  Host -->|Scoped service account| GCS["Approved GCS artifacts"]
  Host -->|Dedicated secret object| Secret["One acceptance bundle"]
  Host -->|Outbound authenticated session| MIOSA["MIOSA control plane"]
  Host --> KVM["Nested virtualization"]
  KVM --> Guests["Firecracker workloads"]

The customer's Terraform principal creates the declared infrastructure.

The runtime worker receives no broad Compute Engine administration permission.

Each worker must use a dedicated bootstrap secret object in the same project.

## GCP-specific acceptance

The instance template must enable nested virtualization.

MIOSA must prove `/dev/kvm` inside the worker before it becomes schedulable.

GCP performance and density must be measured independently instead of copying AWS assumptions.

Provider running state is only a cloud observation.

It is not evidence that the MIOSA runtime, storage, guest boot, and outbound session are ready.

## Current maturity

The GCP Terraform, bootstrap, and host-acceptance contracts are implemented and validated in repository CI.

The module creates a reusable instance template, not an active worker fleet.

GCP remains a parity path until it completes the same real nested-virtualization and acceptance proof required for AWS.

The current public contract is architecture and controlled onboarding preparation.
Production placement must remain disabled until a real provider canary passes and the organization is explicitly enabled.

## What customers will control

- GCP project, region, and zone.
- VPC, subnetwork, routes, and egress.
- Terraform execution identity and state.
- Worker service-account review.
- Cloud KMS, GCS, and Secret Manager policy.
- Provider quota and provider billing.
- Final placement enablement.

Description: Run MIOSA worker capacity inside a customer AWS account or GCP project while MIOSA orchestrates the product.

# Bring Your Own Cloud

Bring Your Own Cloud lets an organization power its product with infrastructure inside its own AWS account or GCP project.

MIOSA remains the orchestration and product control plane.

For servers in your own office, lab, or data center, use [on-premises servers through OpenComputers](/docs/opencomputers/).
Connecting an existing server or cloud VM through OpenComputers does not provision a governed BYOC worker region.
Here, **BYOC** consistently means **Bring Your Own Cloud**.

Activation gated
Infrastructure packages built

## Choose an infrastructure model


    MIOSA operates compute, networking, host lifecycle, capacity, and placement.



    Connect an individual workstation or owned server through an outbound agent session.



    Install a governed MIOSA worker region inside a customer AWS account or Google Cloud project.



    Keep governed workloads in customer infrastructure and use other capacity only where policy permits.


OpenComputers and Bring Your Own Cloud are different products.

OpenComputers connects individual machines.

Bring Your Own Cloud creates a governed cloud capacity region that remains orchestrated by the MIOSA control plane.

  end

  Desired --> Identity

  Hosts -->|Health and runtime census| Evidence

The customer controls the cloud account, network, identity policies, provider resources, and provider bill.

MIOSA controls desired capacity, workload placement, immutable runtime generations, acceptance, scheduling, drain, and reconciliation.

## What runs where

| Layer | MIOSA control plane | Customer cloud |
|---|---|---|
| Organization and workspace policy | Yes | No |
| Desired capacity and placement | Yes | Reflected by worker capacity |
| Provider IAM and networking | Validated and orchestrated | Created and owned |
| Worker hosts | Observed and scheduled | Executed and billed |
| Firecracker workloads | Requested and tracked | Executed |
| Host runtime artifacts | Identified and verified | Downloaded and installed |
| Customer data stores | Bound by the application | Customer-selected |
| Acceptance evidence | Recorded | Produced by the host |

## Provider support


    Terraform and CloudFormation packages define private multi-AZ worker foundations, scoped IAM, immutable templates, and fail-closed acceptance.

    [AWS architecture →](/docs/infrastructure/byoc/aws/)


    Terraform defines the service account, network, firewall, instance template, artifact access, and acceptance handoff.

    [Google Cloud architecture →](/docs/infrastructure/byoc/gcp/)


## Customer onboarding path

Diagram:
sequenceDiagram
  participant Customer
  participant MIOSA
  participant Cloud as Customer cloud
  participant Host as Worker host

  Customer->>MIOSA: create customer-cloud region
  MIOSA-->>Customer: scoped identity and immutable runtime inputs
  Customer->>Cloud: apply reviewed infrastructure package
  Customer->>MIOSA: register provider outputs
  MIOSA->>Cloud: validate identity, network, quota, and image
  MIOSA->>Cloud: request one acceptance worker
  Cloud->>Host: boot verified runtime
  Host->>MIOSA: outbound acceptance evidence
  MIOSA->>MIOSA: verify KVM, storage, runtime, and session
  Customer->>MIOSA: enable placement

Infrastructure creation does not make a region live.

Placement begins only after provider preflight, one real host acceptance, recorded evidence, and explicit enablement.

The packages intentionally fail closed until the per-instance acceptance sequence is certified through a real provider canary.
Cloud-provider state such as EC2 running is never enough to declare a MIOSA host ready.

## BYOC compared with OpenComputers

| | Bring Your Own Cloud | OpenComputers |
|---|---|---|
| Unit | Governed cloud region or host pool | Individual owned machine |
| Provisioning | Terraform or CloudFormation | Agent installation |
| Network | Customer VPC or subnetwork | Existing host network |
| Identity | Cloud IAM and instance identity | MIOSA host registration |
| Capacity | Provider fleet | Connected machines |
| Best for | Enterprise cloud boundaries | Local and owned hardware |

## Provider foundations

| Provider | Current package | Current boundary |
|---|---|---|
| AWS | Terraform and CloudFormation | Private networking, scoped identity, immutable host templates, artifact inputs, and fail-closed acceptance |
| Google Cloud | Terraform | Separate keyless actuator and worker identities, network, firewall, immutable host image, artifact access, and acceptance handoff |

The AWS and Google Cloud packages exist, but general production activation remains gated on a real provider canary and per-host acceptance evidence.
Cloud-provider status alone does not make a MIOSA host schedulable.

## Activation sequence

1. Create the customer-cloud region in MIOSA.
2. Apply the reviewed provider package in the customer account or project.
3. Register the provider outputs with MIOSA.
4. Run identity, network, quota, image, and artifact preflight.
5. Boot one acceptance worker.
6. Verify KVM, storage, runtime generation, authenticated session, and workload execution.
7. Record the evidence.
8. Record separate Sandbox, Computer, and Deployment verification receipts for every workload type that will use the pool.
9. Explicitly enable placement.

Infrastructure creation does not make a region live.

Placement begins only after the full acceptance contract passes.

## Shared responsibility

| Responsibility | Customer | MIOSA | Cloud provider |
|---|---|---|---|
| Account or project ownership | Owns | Validates access | Hosts account services |
| IAM and network policy | Approves and owns | Requests scoped capabilities | Enforces |
| Worker runtime | Supplies capacity | Versions, verifies, and reconciles | Runs infrastructure |
| Workload placement | Sets policy | Schedules and records | Provides compute |
| Provider billing | Pays | Reports MIOSA usage separately | Bills resources |
| Host health | Receives incidents | Verifies runtime census and acceptance | Reports infrastructure state |

## Product contract

Your product should not need a different workflow for every provider.

MIOSA resolves the target, checks policy and capacity, dispatches work, and reports one status and evidence shape.

Use OpenComputers for individual owned machines.

Use customer-cloud regions for governed pools of AWS or Google Cloud capacity.

Use MIOSA-managed compute when the customer does not require a cloud-account boundary.

# Infrastructure options

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/infrastructure/overview
Source: src/routes/docs/infrastructure/overview/+page.md
Description: Choose where workloads run: MIOSA-managed compute, on-premises servers through OpenComputers, or customer-cloud regions.

# Infrastructure options

Run work on MIOSA-managed compute, connect machines you already own, or use governed worker capacity in your own cloud account.

MIOSA provides the organization, workspace, API, and orchestration layer.
The selected infrastructure determines where execution happens and who operates the hardware.

## Choose where work runs

| Your requirement | Infrastructure path | Who operates the machines? |
|---|---|---|
| Start without owning servers | MIOSA-managed compute | MIOSA |
| Use servers in your office, lab, or data center | On-premises servers connected through OpenComputers | Your organization |
| Use a workstation, a GPU machine, or an existing hosted server | OpenComputers | You or your hosting provider |
| Provision a governed worker pool in your AWS account or Google Cloud project | Bring Your Own Cloud (BYOC) | Shared between your organization, MIOSA, and the cloud provider |
| Use more than one of these locations | Hybrid infrastructure with explicit workload placement | Depends on each selected target |


    MIOSA operates the compute capacity, host lifecycle, and platform networking.
    Use it when you want to create resources without maintaining your own servers.


    Connect a supported server in your office, lab, or data center through OpenComputers.
    Your organization retains responsibility for the hardware, operating system, power, storage, and local network.

    [OpenComputers overview →](/docs/opencomputers/)


    Connect a customer-controlled machine through an authenticated outbound agent session.
    That machine can be an on-premises server, workstation, GPU host, or an existing server at a hosting provider.

    [Connect a machine →](/docs/opencomputers/connect/)


    Provision a governed MIOSA worker region inside a customer AWS account or Google Cloud project.
    This is a pool of worker capacity with provider-specific onboarding and acceptance checks.

    [BYOC architecture →](/docs/infrastructure/byoc/overview/)


## Compare capabilities

The resource type determines the execution model; the location alone does not.
Check the selected host or region before dispatching work.

| Resource | Execution and desktop | Persistence and operation |
|---|---|---|
| Managed Sandbox | Isolated Linux execution for code and agents; use a Computer for a full desktop. | Follow the [snapshot and persistence lifecycle](/docs/develop/snapshots/); MIOSA operates the host. |
| Managed Computer | Linux desktop, browser automation, and command execution; wait for desktop readiness. | Follow [Computer readiness](/docs/computers/fast-start/) and recovery guidance; MIOSA operates the host. |
| OpenComputer | Runs on your existing machine with its advertised capabilities; direct execution uses the agent's OS permissions. | You maintain the OS, disks, backups, network, and agent service; desktop and GPU use depend on the host. |
| BYOC worker capacity | Accepted worker pools in your cloud account; available resource types depend on the provider rollout. | Your cloud account owns the infrastructure; follow provider acceptance and [shared responsibility](/docs/infrastructure/shared-responsibility/). |

A GPU in an OpenComputer is usable only when its driver, model runtime, and selected workflow support it.
It does not imply availability of a managed GPU Sandbox.
A published application needs a deployment target; connecting a host does not automatically configure Docker Host on it.

## Availability before you choose

- **Managed Sandboxes:** generally available according to the [availability page](/docs/availability/).
- **Managed Computers:** partner preview; desktop provisioning and readiness remain in hardening.
- **OpenComputers:** verify account access and the installed agent's capabilities before choosing a host; registration alone proves neither readiness nor feature parity.
- **BYOC:** activation gated on provider canary and host acceptance; infrastructure packages alone are not production capacity.

[Connect your first Linux server](/docs/opencomputers/connect/) walks through installation, registration, a completed command, service startup, and disconnection.
If an existing host fails, use [OpenComputers troubleshooting](/docs/opencomputers/troubleshooting/).

## How the options relate

  Connected --> Other["Workstations, GPU machines,<br/>or existing hosted servers"]
  BYOC --> AWS["Your AWS account"]
  BYOC --> GCP["Your Google Cloud project"]

**On-premises** describes the location and operating responsibility of the hardware.
**OpenComputers** is the connection and remote-operation path for a supported machine.
An on-premises server connected through OpenComputers is an **OpenComputer**.
OpenComputers also works with supported machines outside your premises.

**BYOC** means **Bring Your Own Cloud** in these docs.
Connecting an existing cloud VM as an OpenComputer does not make it a governed BYOC worker pool.

## Hybrid infrastructure and placement

Hybrid infrastructure combines two or more infrastructure locations in one product.
For example, an agent can run a command on an explicitly selected on-premises host while another task uses a MIOSA-managed Sandbox.
Choose each target according to its capabilities, data access, and permitted execution location.

Do not assume that an offline or full on-premises host causes automatic cloud overflow.
A fallback target needs explicit authorization, compatible capabilities, access to the required files and secrets, and a recovery plan for any unfinished work.
A common API does not make hardware, desktop support, or isolation identical across targets.

## Availability and responsibility

Connecting a host uses the MIOSA control plane; it does not install the complete MIOSA platform on your premises.
Work can execute on your machine while commands, status, output, and any requested artifacts pass through the configured MIOSA services.
Use the [OpenComputers security model](/docs/opencomputers/security/) to understand connectivity and data boundaries.

AWS and Google Cloud infrastructure packages exist, but production activation remains subject to provider acceptance and live canary evidence.
Check the provider guide for the applicable maturity boundary before planning a rollout.

# Shared responsibility

Source: src/routes/docs/infrastructure/shared-responsibility/+page.md
Description: Responsibility boundaries for MIOSA-managed, on-premises servers connected through OpenComputers, and customer-cloud infrastructure.

Infrastructure ownership changes who operates each layer.

The product should make those boundaries visible before a workload is placed.

OpenComputers includes on-premises servers as well as workstations and other existing customer-controlled machines.
The customer operates the connected machine and its local environment; MIOSA operates the connected control-plane service.

## Responsibility matrix

| Responsibility | MIOSA-managed | OpenComputers, including on-premises | Bring Your Own Cloud |
|---|---|---|---|
| Control-plane service | MIOSA | MIOSA | MIOSA |
| Physical hardware or cloud account | MIOSA | Customer | Customer |
| Site power, cooling, and physical access | MIOSA or its provider | Customer or its hosting provider | Cloud provider |
| Host operating system | MIOSA | Customer | Shared through certified image and customer account |
| Host capacity | MIOSA | Customer | Customer provider resources, MIOSA desired state |
| Network perimeter | MIOSA | Customer host network | Customer VPC or subnetwork |
| Runtime generation | MIOSA | Customer-approved agent update | MIOSA-signed generation, customer-reviewed installation |
| Workload placement | MIOSA policy | MIOSA policy within connected hosts | MIOSA policy within enabled customer pools |
| Provider billing | MIOSA | Customer hardware and network | Customer cloud bill |
| Application data and backup policy | Application owner | Application owner, including local disks and services | Application owner |
| Drain and workload proof | MIOSA | MIOSA plus host availability | MIOSA plus provider observation |

## MIOSA responsibilities

- Maintain desired state and placement policy.
- Issue scoped, retry-safe operations.
- Verify immutable runtime generations.
- Record host acceptance evidence.
- Require fresh host sessions before placement.
- Reconcile provider and runtime drift.
- Drain workloads before an authorized teardown.
- Report health, capacity, usage, and next actions.

## Customer responsibilities

- Choose the infrastructure ownership model.
- For on-premises hosts, maintain physical security, power, cooling, hardware, operating-system updates, disks, and network availability.
- Set the connected agent's permissions and monitor its service and outbound connectivity.
- Review which command output, artifacts, desktop streams, and model requests may leave your premises.
- Review cloud IAM, network, and infrastructure packages.
- Maintain cloud quotas, billing, and organization policy.
- Protect Terraform state and provisioning identities.
- Select data stores, retention, backup, and recovery policy.
- Approve placement into a customer-cloud region.
- Revoke access when the trust relationship should end.
- Coordinate destructive cloud changes with MIOSA drain state.

## Cloud-provider responsibilities

- Operate the underlying cloud services.
- Enforce the configured provider identity and network policy.
- Report provider state and billing.
- Provide the compute, storage, and network primitives requested by the customer.

## On-premises maintenance

Before restarting or disconnecting an on-premises server, stop new work and inspect the jobs and local services still running on it.
Confirm the outcome of interrupted operations before retrying them.
After maintenance, verify connectivity and required capabilities with a small command on that exact host.
An offline status does not prove that local processes stopped or that work moved to another machine.

See [OpenComputers](/docs/opencomputers/) for the execution and data boundaries.

## Governed worker-pool change order

Diagram:
sequenceDiagram
  participant Customer
  participant MIOSA
  participant Provider
  participant Host

  Customer->>MIOSA: request infrastructure change
  MIOSA->>Host: stop new placement and drain
  Host-->>MIOSA: zero-runtime evidence
  MIOSA-->>Customer: safe provider change authorized
  Customer->>Provider: apply reviewed change
  Provider-->>MIOSA: provider observation
  Host->>MIOSA: fresh acceptance and heartbeat
  MIOSA-->>Customer: placement may be enabled

Do not terminate a host because its time-to-live expired or its provider record looks stale.

Termination requires exact ownership plus fresh drain, zero-runtime, and session-revocation evidence.

A running VM is not sufficient.
The runtime, storage, authenticated session, guest boot, capability advertisement, and placement scope must also agree.

Description: Ship a white-label SaaS where your end-users never see the MIOSA brand. Isolated compute, custom domains, branded previews, usage rollup, and webhooks  -  all under your domain.

# Build your product on MIOSA

MIOSA gives you the full compute and preview infrastructure. You own the product, the brand, and the user relationship. Your customers never see "MIOSA".

This section covers everything you need to ship a white-label SaaS on top of MIOSA: per-user provisioning, custom domains, secure iframe embeds, webhooks, usage metering, and abuse controls.

---

## Core building blocks


    Build the server-side control plane for prompt dispatch, device assignment, event streaming, artifact storage, and quota enforcement.



    Run dedicated Fractal instances for massive-scale structured data and computation, secure and isolated for enterprise and government.



    Provision customer-owned sandboxes, embed previews, use branded domains, and roll usage up to your users.



    Keep API keys server-side while safely embedding sandbox previews and customer-facing runtime surfaces.



    Clone reference product patterns and adapt them to your own backend and frontend.


---

## What white-label tenants get

| Capability | What it means for your product |
|---|---|
| **Isolated sandboxes per user** | Each customer project runs in its own microVM with its own filesystem, network, and process tree. |
| **Custom preview domains** | Sandbox previews serve from `*.example.com` instead of `*.sandbox.miosa.ai`. |
| **Short-lived preview tokens** | Mint a server-side token, pass it to the browser  -  never expose your API key client-side. |
| **Webhook lifecycle events** | Receive `sandbox.running`, `sandbox.destroyed`, and more at your own HTTPS endpoint. |
| **Usage rollup by user** | Query compute usage keyed to your own `external_user_id` for per-seat billing. |
| **Per-user quotas** | Set max sandboxes, max CPU, or max runtime per user to prevent runaway spend. |
| **Branded failure pages** | 502 and 404 errors in previews show your logo, not MIOSA's. |
| **Full filesystem and terminal access** | Expose a file tree, terminal, or run-button in your UI using the SDK  -  no shell into MIOSA required. |

---

## Architecture patterns

Three deployment patterns cover the vast majority of integrations. All three keep your `msk_*` API key server-side.

Diagram:
flowchart TB
  subgraph "Pattern 1  -  Server-side proxy"
    A1[Browser] -->|Your API routes| B1[Your backend]
    B1 -->|msk_ API key| C1[MIOSA API]
    B1 -->|Preview token| A1
    A1 -->|iframe src| D1[preview.miosa.ai / your domain]
  end

  subgraph "Pattern 2  -  Backend-for-Frontend (BFF)"
    A2[Browser] -->|REST/GraphQL| B2[BFF layer]
    B2 -->|msk_ API key| C2[MIOSA API]
    B2 -->|Short-lived JWT| A2
    A2 -->|SDK calls with JWT| C2
  end

  subgraph "Pattern 3  -  Direct with browser tokens"
    A3[Browser] -->|Auth request| B3[Your backend]
    B3 -->|Mint browser token| C3[MIOSA API]
    B3 -->|mp_ token| A3
    A3 -->|MIOSA SDK token| C3
  end

### Pattern 1  -  Server-side proxy (recommended for most teams)

Your backend owns all MIOSA calls. The browser only receives a short-lived preview URL from your API. This is the simplest pattern and the one used in the `whitelabel-saas` example.

**When to use:** You already have a backend. You want the tightest control over what each user can do. No SDK needed in the browser.

### Pattern 2  -  Backend-for-Frontend (BFF)

A thin BFF layer authenticates the user, resolves their MIOSA workspace/project IDs, and returns a short-lived JWT. The browser then calls MIOSA directly using that token.

**When to use:** High-volume preview-heavy products where round-tripping every terminal keystroke through your backend adds latency.

### Pattern 3  -  Direct with browser tokens

Your backend mints a scoped browser token (`mp_...`) once. The browser uses `@miosa/sdk` directly with that token for file reads, exec calls, and preview embeds.

**When to use:** Interactive coding tools or IDEs where the browser needs low-latency direct access to the sandbox.

## Five-minute path for new integrators

1. [One-time setup](/docs/platform/white-label)  -  register your domain, set branding, configure a webhook
2. [Provision a sandbox per user](/docs/platform/white-label)  -  `client.sandboxes.create(external_user_id=...)`
3. [Embed the preview](/docs/platform/white-label)  -  mint a token server-side, drop an `<iframe>` in your UI
4. [Handle lifecycle events](/docs/platform/white-label)  -  react to `sandbox.running`, `sandbox.destroyed`
5. [Bill by user](/docs/platform/white-label)  -  query usage keyed to your `external_user_id`

# Backend orchestration

Source: src/routes/docs/integrations/backend-orchestration/+page.md
Description: Backend patterns for dispatching prompts into MIOSA sandboxes, computers, and local devices.

# Backend orchestration

Your backend is the control plane for products built on MIOSA. It owns the user
session, product permissions, billing policy, model routing, agent roster,
connector grants, and approval rules. MIOSA owns the execution substrate:
sandboxes, computers, files, exec, previews, artifacts, events, snapshots, and
deployments.

Use this guide when you are building products like app builders, artifact
workspaces, Polsia-style operators, Cofounder / Co-Founder AI-style company
agents, Nebula-style virtual devices, or Heuresis-style encoded workspaces.

Use tenant or workspace API keys from your backend. Browsers should receive
short-lived browser tokens, preview tokens, or your own session-bound proxy
responses. Do not put `msk_*` keys in client code.

---

## Backend responsibilities


    Map your account, workspace, user, project, document, or app record to MIOSA
    ownership fields before creating resources.



    Route work to a sandbox for code/files, a computer for browser/desktop, or a
    local device when customer-owned hardware is required.



    Send the user's task into the selected agent runtime and assigned device.
    The agent should work inside that device, not build locally and upload later.



    Normalize tool calls, command output, file writes, screenshots, preview
    readiness, artifacts, approvals, and final URLs into one product event stream.



    Store MIOSA resource ids, artifact ids, snapshot ids, deployment ids,
    connector grant ids, and request ids next to your own product records.



    Apply quota, budget, approval, network, and connector rules before the agent
    can spend credits, send messages, publish apps, or use sensitive credentials.


---

## Reference flow

Diagram:
sequenceDiagram
  participant User
  participant App as Your backend
  participant Queue
  participant Agent
  participant S as MIOSA sandbox
  participant C as MIOSA computer
  participant UI as Your frontend

  User->>App: prompt
  App->>App: authorize, resolve workspace/project/user
  App->>S: create or resume runtime
  App->>Queue: enqueue agent run
  Queue->>Agent: assigned runtime + device + scoped tools
  Agent->>S: write files and run commands in /workspace
  S-->>App: events, stdout, file changes, preview URL
  Agent->>C: browser QA when needed
  C-->>App: screenshots and browser events
  App-->>UI: normalized live run stream
  Agent->>S: publish or create artifacts
  App-->>User: artifact, preview, or deployment URL

The important boundary is simple: your backend orchestrates; the agent executes
inside a MIOSA device.

---

## Prompt dispatch contract

Model every agent run as a prompt dispatched into an assigned device.

```typescript
type DevicePromptDispatch = {
  tenantId: string;
  workspaceId: string;
  projectId?: string;
  userId: string;
  deviceType: "sandbox" | "computer" | "local";
  deviceId: string;
  runtime: "osa" | "codex" | "claude-code" | "hermes" | "gemini-cli" | "opencode" | "custom";
  prompt: string;
  cwd?: string;
  connectors?: string[];
  approvalPolicy: "auto" | "confirm-risky" | "manual";
  idempotencyKey: string;
};
```

The output stream should use one shape even when runtimes differ:

| Event | Use it for |
|---|---|
| `run.started` | The backend accepted the prompt and assigned a device |
| `tool.started` / `tool.completed` | Agent tool calls, MCP calls, connector calls |
| `command.output` | stdout/stderr from sandbox or computer commands |
| `file.changed` | Files created, edited, renamed, or deleted |
| `preview.ready` | Live server URL is ready |
| `artifact.created` | PDF, DOCX, image, HTML, ZIP, report, screenshot, or generated code output |
| `approval.required` | The agent wants to do something sensitive |
| `deployment.ready` | Stable public app URL is available |
| `run.failed` | Typed failure with request id and recovery path |

---

## Backend resource model

Store both your product ids and MIOSA ids. Do not force users or agents to
discover partial state after a retry.

```sql
agent_runs
  id
  tenant_id
  workspace_id
  project_id
  user_id
  prompt
  runtime
  device_type
  device_id
  sandbox_id
  computer_id
  deployment_id
  status
  idempotency_key
  created_at
  updated_at

agent_run_events
  id
  run_id
  type
  payload_json
  request_id
  created_at

agent_artifacts
  id
  run_id
  miosa_artifact_id
  path
  content_type
  size_bytes
  preview_url
  download_url
  created_at
```

For generated app products, also store the current persistent sandbox and latest
deployment per project:

```sql
projects
  id
  current_sandbox_id
  current_computer_id
  current_deployment_id
  primary_device_type
  primary_device_id
```

---

## SDK shape

Use the SDK language that matches your backend. The product logic is the same in
every language.


    Node, Next.js route handlers, queues, AI SDK harnesses, and product backends.



    FastAPI, Django, Flask, data jobs, artifact generation, and Python agent loops.



    High-concurrency orchestration services, workers, queues, and control planes.



    Phoenix control planes, LiveView progress streams, queues, and long-running orchestration.


The minimum backend loop:

```text
1. Authenticate your user.
2. Resolve their workspace/project/user attribution.
3. Create or resume a sandbox/computer.
4. Dispatch the prompt into that device.
5. Stream events back to your UI.
6. Store artifacts, snapshots, previews, and deployments.
7. Enforce budget, quota, connector, and approval policy.
```

---

## Recovery rules

Production backends need to recover from partial progress.

| Failure | Backend behavior |
|---|---|
| Create succeeded, upload failed | Return the sandbox id and retry command; do not hide the partial resource |
| Agent runtime crashed | Keep the device and events; let user retry into the same workspace |
| Preview failed | Surface logs and process state; do not delete files automatically |
| Sandbox stopped | Resume or fork from snapshot when persistence is available |
| Budget exceeded | Stop new work and show the usage source |
| Connector authorization missing | Return a connect-account action, not a generic 500 |
| Publish failed | Keep the sandbox preview and release artifact for retry |

Use idempotency keys on mutations so retries do not create duplicate sandboxes,
deployments, or app records.

Description: How MIOSA's published compute rates compare with Freestyle, E2B, Railway and Vercel Sandbox. Competitor prices checked 2026-10-20.

# Compute provider comparison

This page compares **compute price** across the platforms customers evaluate against MIOSA.
Every MIOSA figure is from its live pricing API and its published price per size.
Every competitor figure is from the vendor's own pricing page, checked **2026-10-20**, with the source listed at the end.

For capabilities and measured performance, see [MIOSA vs other platforms](/docs/compare).
That section is the current, verified comparison, and this page does not repeat it.

  <span style="display:inline-flex;align-items:center;gap:.45rem;padding:.35rem .7rem;border:1px solid var(--dbd);border-radius:10px;">Vercel Sandbox</span>
</div>

## Pricing model

| Provider | Model | Entry price | Free tier |
|---|---|---|---|
| **MIOSA** | One published price per size, metered by the second; plans set what is included and a size ceiling | Free $0 · Developer $20/mo · Business $500/mo · Enterprise $2,000/mo | Free: $1 of usage every month, no card needed |
| **Freestyle** | Subscription plus hourly usage | Hobby $50/mo | Free plan; the included allowance resets every month |
| **E2B** | Subscription plus per-second usage | Pro $150/mo | Hobby: free, plus a one-time $100 credit |
| **Railway** | Subscription credited against usage | Pro $20/mo, credited | not compared here |
| **Vercel Sandbox** | Usage on top of a Pro seat | Pro $20/mo credit plus a $20 seat | not compared here |

## Compute cost, normalized

Same box everywhere: **4 vCPU / 8 GiB RAM, running, per hour**, computed from each vendor's published unit rates.
MIOSA figures come from the live pricing API (`GET /api/v1/pricing`): each size has one hourly price, and the 4 vCPU / 8 GiB size is $0.1785.

| Provider | vCPU rate | RAM rate | **4 vCPU + 8 GiB / hr** |
|---|---|---|---|
| **MIOSA** | $0.027216 / vCPU-hr | $0.0087075 / GiB-hr | **$0.1785** (compute only; disk and egress metered separately) |
| **Railway** | $0.02779 / vCPU-hr | $0.01389 / GiB-hr | **~$0.22** |
| **Freestyle** | $0.04032 / vCPU-hr | $0.0129 / GiB-hr | **~$0.26** |
| **E2B** | $0.0504 / vCPU-hr | $0.0162 / GiB-hr | **~$0.33** (+ $150/mo on Pro) |
| **Vercel Sandbox** | $0.128 / active vCPU-hr | $0.0212 / GB-hr | **~$0.68** (active CPU only) |

These are list prices for running compute only, and they move.
MIOSA also meters disk and network egress; several providers bill storage, egress, and higher multi-region rates on top.
Vercel bills CPU only while it is active.
Size the shape you care about in the calculator below.

## Cost calculator

Drag to size a box and see the estimated monthly cost per provider, computed live from the list rates above.

## Where MIOSA fits best

- **One price per size**: every MIOSA plan pays the same hourly price for a size, plus the same rates for disk and egress; plans only change caps and concurrency. Developer hard-stops at a $0 balance.
- **Sandboxes, computers, and deployments** on one API, with [white-label branding](/docs/platform/white-label) for your own customers.
- **Bring your own hardware or cloud**: [OpenComputers](/docs/opencomputers/) and [Bring your own cloud](/docs/infrastructure/byoc/overview/).
- **Capabilities and measured performance**: see [MIOSA vs other platforms](/docs/compare) and the [Benchmarks](/docs/benchmarks).

# Example Apps

URL: https://miosa.ai/docs/integrations/examples
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/integrations/examples
Source: src/routes/docs/integrations/examples/+page.md
Description: Four full-stack white-label examples you can clone, run locally, and adapt to your own stack.

# Example apps

Four complete, runnable examples. Each demonstrates a different frontend stack and a different set of white-label capabilities. Clone the repo and follow the "Run locally" steps below each entry.

Every example should pass three proofs before you adapt it: the application starts locally, its MIOSA resource resolves to the intended Workspace and Project, and the browser never receives a server API key.

## Pick an example

| Goal | Start with | Completion proof |
|---|---|---|
| Server-rendered integration | `whitelabel-saas` | A customer Sandbox opens through a scoped Preview token |
| React product with embedded terminal | `whitelabel-react-saas` | Refresh resumes the same attributed Sandbox |
| Next.js marketplace or builder | `whitelabel-nextjs-marketplace` | Multiple Projects remain separated by canonical IDs |
| Vue learning environment | `whitelabel-vue-tutor` | Quotas and teardown apply to the correct end user |

Run the example unchanged first.
Record the successful local URL and MIOSA resource IDs, then adapt one concern at a time.

All examples live in `examples/` at the root of the [MIOSA GitHub repository](https://github.com/Miosa-osa/miosa).

---

## whitelabel-saas

**Stack:** Python (Flask) backend + plain HTML/JS frontend

**What it demonstrates:**

- One-time tenant setup: custom preview domain, branding, webhook registration
- Per-customer sandbox provisioning with `external_user_id`, `external_project_id`, and `metadata`
- Server-side preview token minting and iframe embed
- HMAC-SHA256 webhook signature verification
- Teardown by `external_user_id` (cancellation flow)

This is the canonical reference example. Every concept in the [white-label walkthrough](/docs/platform/white-label) maps directly to code in this example.

**Run locally:**

```bash
cd examples/whitelabel-saas
python -m venv .venv && source .venv/bin/activate
pip install -r requirements.txt

cp .env.example .env
# Edit .env  -  fill in MIOSA_API_KEY

python setup.py      # one-time tenant setup
python app.py        # server on http://localhost:8000
# Open index.html in a browser for the embed demo
```

**GitHub:** [`examples/whitelabel-saas`](https://github.com/Miosa-osa/miosa/tree/main/examples/whitelabel-saas)

---

## whitelabel-react-saas

**Stack:** React 18 (Vite) frontend + Express.js BFF

**What it demonstrates:**

- BFF pattern: Express mints browser tokens; React uses `@miosa/sdk` directly in the browser
- Live terminal inside an iframe powered by the TypeScript SDK
- Per-user sandbox state stored in the BFF session
- Sandbox resume on page refresh (poll for `state === "running"` before showing the embed)
- Token refresh on `miosa:preview:expired` message event

**Run locally:**

```bash
cd examples/whitelabel-react-saas
pnpm install

cp .env.example .env
# Edit .env  -  fill in MIOSA_API_KEY

pnpm dev   # starts both Express (port 3001) and Vite (port 5173)
# Open http://localhost:5173
```

**GitHub:** [`examples/whitelabel-react-saas`](https://github.com/Miosa-osa/miosa/tree/main/examples/whitelabel-react-saas)

---

## whitelabel-nextjs-marketplace

**Stack:** Next.js 15 (App Router) full-stack

**What it demonstrates:**

- Next.js Route Handlers as the BFF: token minting without a separate Express server
- Seller onboarding: sandbox provisioned on first login, re-used on return
- Multi-project listing: sandboxes filtered by `external_user_id` and rendered as cards
- Usage display: per-seller compute hours fetched with `client.usage.get(external_user_id)`
- Custom `next.config.js` to proxy sandbox previews through the Next.js server (avoid CORS for embedded iframes)

**Run locally:**

```bash
cd examples/whitelabel-nextjs-marketplace
pnpm install

cp .env.local.example .env.local
# Edit .env.local  -  fill in MIOSA_API_KEY

pnpm dev   # starts on http://localhost:3000
```

**GitHub:** [`examples/whitelabel-nextjs-marketplace`](https://github.com/Miosa-osa/miosa/tree/main/examples/whitelabel-nextjs-marketplace)

---

## whitelabel-vue-tutor

**Stack:** Vue 3 (Vite) frontend + Express.js backend

**What it demonstrates:**

- Per-lesson sandbox lifecycle: fresh sandbox per lesson, destroyed on completion
- Quota enforcement: custom middleware rejects `sandbox.create` if the user has reached their limit
- Public share links with a 15-minute TTL for peer review
- File-tree component: reads the sandbox filesystem via `client.files.list(sandboxId, "/")`
- Run-button component: streams exec output via `client.exec.stream(sandboxId, "npm test")`

**Run locally:**

```bash
cd examples/whitelabel-vue-tutor
pnpm install

cp .env.example .env
# Edit .env  -  fill in MIOSA_API_KEY

pnpm dev   # starts both Express (port 3001) and Vite (port 5174)
# Open http://localhost:5174
```

**GitHub:** [`examples/whitelabel-vue-tutor`](https://github.com/Miosa-osa/miosa/tree/main/examples/whitelabel-vue-tutor)

# External computer providers

URL: https://miosa.ai/docs/integrations/external-computers
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/integrations/external-computers
Source: src/routes/docs/integrations/external-computers/+page.md
Description: Which kinds of compute MIOSA can run on today, and why connecting a third-party sandbox or desktop provider is not offered.

# External computer providers

MIOSA runs your workloads on its own cloud by default, and it can also run them on hardware you own or operate yourself.
Two bring-your-own paths are supported today.
Connecting a third-party sandbox or desktop provider such as Orgo, E2B, or Daytona is **not** supported today: those adapters are not part of the product.

## Where compute can run

| Source | Status | Where it runs |
|---|---|---|
| MIOSA cloud | Available | MIOSA-managed sandboxes and computers |
| OpenComputers | Available | Hardware you own or rent, connected over an outbound WebSocket |
| Bring your own cloud | Available, by onboarding | Worker capacity inside your own AWS or Google Cloud account |
| Third-party provider adapter | Not offered | - |

Sandboxes run on Firecracker by default.
SOMA is available to every customer, and `auto` lets the platform choose.
See [Choosing a runtime](/docs/soma/choosing-a-runtime/).

## Run on hardware you own

[OpenComputers](/docs/opencomputers/) is MIOSA's bring-your-own-hardware path.
You run a small host agent on a machine you control, and it enrolls with MIOSA over an outbound WebSocket.
The machine then appears to your application with the same interface as a MIOSA computer, so your product drives both without branching on the host.
Start with [Connect a host](/docs/opencomputers/connect/).

## Run in your own cloud account

For worker capacity inside your own AWS or Google Cloud account, MIOSA has a separate onboarding path.
See [Bring your own cloud](/docs/infrastructure/byoc/overview/).

## What is not offered

MIOSA does not currently provide adapters that connect a third-party compute provider.
There is no supported way to drive an Orgo, E2B, Daytona, or similar machine through the MIOSA API today, and you cannot connect a third-party API key to run machines inside MIOSA.

If you need capacity outside the MIOSA cloud, use [OpenComputers](/docs/opencomputers/) on hardware you control, or [Bring your own cloud](/docs/infrastructure/byoc/overview/) in your own cloud account.

# Webhooks

URL: https://miosa.ai/docs/integrations/webhooks
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/integrations/webhooks
Source: src/routes/docs/integrations/webhooks/+page.md
Description: Subscribe to sandbox and deployment lifecycle events, verify HMAC-SHA256 signatures, handle retries, and test locally.

# Webhooks

MIOSA sends HTTP `POST` requests to your endpoint whenever a sandbox or deployment changes state. Use webhooks to update your database, notify users, trigger downstream actions, or bill for compute.

---

## Event taxonomy

### Sandbox events

| Event | Fires when |
|---|---|
| `sandbox.created` | The sandbox row is inserted. The VM may still be booting. |
| `sandbox.running` | The sandbox is fully booted and ready. `external_user_id` is available. |
| `sandbox.paused` | The sandbox was paused due to an idle timeout or an explicit API call. |
| `sandbox.resumed` | A paused sandbox was resumed. |
| `sandbox.destroyed` | The sandbox was permanently deleted. |
| `sandbox.error` | The sandbox failed to boot or encountered a runtime error. |

### Deployment events

| Event | Fires when |
|---|---|
| `deployment.created` | A new deployment was created. |
| `deployment.build_started` | A build started for a new version. |
| `deployment.build_succeeded` | A build finished successfully. |
| `deployment.build_failed` | A build failed. The `error` field contains the failure reason. |
| `deployment.published` | A version was promoted to the active release. |
| `deployment.domain_attached` | A custom domain was verified and attached. |

### Forge events

Every Forge event names its repository in the payload (`repository.id`, `repository.full_name`, `repository.owner`, `repository.slug`), so one organization subscription can route events from every repository. Subscriptions cannot be limited to a single repository.

| Event | Fires when |
|---|---|
| `forge.push` | A push to a repository was accepted. |
| `forge.pull_request` | A pull request was opened, closed, reopened, merged or reviewed. |
| `forge.check` | A check reported on a pull request or a commit. The payload includes `commit_sha`. |

---

## Payload structure

Every webhook delivery has the same envelope:

```json
{
  "id": "evt_01hzqmrkntq6g9gxnqhvpa8c7t",
  "type": "sandbox.running",
  "created_at": "2026-05-25T14:32:10Z",
  "data": {
    "id": "sbx_01hzq5pnmpgt6vdwp0r8d23c5n",
    "state": "running",
    "external_user_id": "user_42",
    "external_project_id": "proj_lumen_1",
    "metadata": {
      "customer_id": "user_42",
      "project_name": "brand-refresh",
      "source": "lumen-whitelabel"
    },
    "preview_url": "https://3000-sbx01hzq.sandbox.example.com"
  }
}
```

The `id` field is a unique event ID. Use it to deduplicate deliveries.

---

## HMAC-SHA256 signature verification

Every delivery includes a `Miosa-Signature` header:

```
Miosa-Signature: t=1716645130,v1=a3f2c8...
```

- `t`  -  Unix timestamp (seconds) when MIOSA signed the request
- `v1`  -  HMAC-SHA256 hex digest of `"<t>.<raw_body>"`

The signed payload is `timestamp + "." + raw request body bytes`. Verify before parsing the JSON.

Reject events where the timestamp `t` is more than 300 seconds (5 minutes) in the past or future. This prevents replay attacks using captured valid signatures.

```python

def verify_miosa_signature(body: bytes, header: str, secret: str) -> bool:
    """Return True if the signature is valid."""
    try:
        parts = dict(item.split("=", 1) for item in header.split(","))
        timestamp = parts["t"]
        received = parts["v1"]
    except (KeyError, ValueError):
        return False

    # Reject stale events.
    if abs(time.time() - int(timestamp)) > 300:
        return False

    signed = f"{timestamp}.{body.decode('utf-8')}"
    expected = hmac.new(
        secret.encode("utf-8"),
        signed.encode("utf-8"),
        hashlib.sha256,
    ).hexdigest()

    return hmac.compare_digest(expected, received)

# Flask example
from flask import request, jsonify

@app.post("/webhooks/miosa")
def miosa_webhook():
    raw = request.get_data()
    sig = request.headers.get("Miosa-Signature", "")

    if not verify_miosa_signature(raw, sig, WEBHOOK_SECRET):
        return jsonify({"error": "invalid signature"}), 401

    event = request.get_json()
    handle_event(event)
    return jsonify({"ok": True}), 200
```

```typescript

function verifyMiosaSignature(
  rawBody: Buffer,
  header: string,
  secret: string,
): boolean {
  const parts = Object.fromEntries(
    header.split(",").map((p) => p.split("=") as [string, string]),
  );
  const { t: timestamp, v1: received } = parts;
  if (!timestamp || !received) return false;

  // Reject stale events.
  if (Math.abs(Date.now() / 1000 - Number(timestamp)) > 300) return false;

  const signed = `${timestamp}.${rawBody.toString("utf8")}`;
  const expected = crypto
    .createHmac("sha256", secret)
    .update(signed)
    .digest("hex");

  return crypto.timingSafeEqual(
    Buffer.from(expected, "hex"),
    Buffer.from(received, "hex"),
  );
}

// Express example
app.post("/webhooks/miosa", express.raw({ type: "*/*" }), (req: Request, res: Response) => {
  const sig = req.headers["miosa-signature"] as string ?? "";
  if (!verifyMiosaSignature(req.body, sig, process.env.MIOSA_WEBHOOK_SECRET!)) {
    return res.status(401).json({ error: "invalid signature" });
  }
  const event = JSON.parse(req.body.toString());
  handleEvent(event);
  res.json({ ok: true });
});
```

```go

func verifyMiosaSignature(body []byte, header, secret string) bool {
    parts := map[string]string{}
    for _, part := range strings.Split(header, ",") {
        kv := strings.SplitN(part, "=", 2)
        if len(kv) == 2 {

    return hmac.Equal([]byte(expected), []byte(received))
}

func webhookHandler(w http.ResponseWriter, r *http.Request) {
    body, _ := io.ReadAll(r.Body)
    sig := r.Header.Get("Miosa-Signature")

    if !verifyMiosaSignature(body, sig, webhookSecret) {

        return
    }

    // parse and handle body ...
    w.WriteHeader(http.StatusOK)
}
```

---

## Idempotency

MIOSA may deliver the same event more than once (network retries, at-least-once semantics). Make your handler idempotent by storing the event `id` and discarding duplicates:

```python
processed_events = set()  # use a database or cache in production

def handle_event(event: dict) -> None:
    event_id = event["id"]
    if event_id in processed_events:
        return  # duplicate  -  skip
    processed_events.add(event_id)

    match event["type"]:
        case "sandbox.running":
            notify_user(event["data"]["external_user_id"])
        case "sandbox.destroyed":
            release_resources(event["data"]["id"])
        case "sandbox.error":
            alert_oncall(event["data"])
```

---

## Retry policy

| Attempt | Delay |
|---|---|
| 1 (initial) | Immediate |
| 2 | 1 minute |
| 3 | 5 minutes |
| 4 | 30 minutes |
| 5 | 1 hour |
| 6 | 2 hours |
| 7 | 4 hours |
| 8 | 8 hours |

MIOSA makes up to eight delivery attempts over roughly 15.5 hours (within a 24-hour window), then drops the event. If your endpoint is unreachable, check the webhook delivery log in the MIOSA dashboard.

Return a `2xx` status code within **10 seconds** to acknowledge receipt. If your processing takes longer, acknowledge immediately and handle the event asynchronously.

---

## Register a webhook

```python
hook = client.webhooks.create(
    url="https://example.com/webhooks/miosa",
    events=[
        "sandbox.created",
        "sandbox.running",
        "sandbox.paused",
        "sandbox.destroyed",
        "sandbox.error",
    ],
    description="Lumen lifecycle events",
)

# The secret is returned only on creation. Store it immediately.
print(hook["secret"])  # MIOSA_WEBHOOK_SECRET=...
```

```typescript
const hook = await client.webhooks.create({
  url: "https://example.com/webhooks/miosa",
  events: [
    "sandbox.created",
    "sandbox.running",
    "sandbox.paused",
    "sandbox.destroyed",
    "sandbox.error",
  ],
  description: "Lumen lifecycle events",
});

// The secret is returned only on creation. Store it immediately.
console.log(hook.secret); // MIOSA_WEBHOOK_SECRET=...
```

The webhook secret is returned once at creation. If you lose it, delete the webhook and create a new one.

---

## Local testing

Use a tunnel to expose your local server during development:

```bash
# Option 1  -  ngrok
ngrok http 8000
# Copy the https URL, set MIOSA_WEBHOOK_URL in .env

# Option 2  -  cloudflared
cloudflared tunnel --url http://localhost:8000
```

Then run the one-time setup script to register the tunnel URL as your webhook endpoint. When you restart the tunnel and get a new URL, update the webhook:

```python
# Update an existing webhook's URL
client.webhooks.update("whk_abc123", url="https://new-tunnel.ngrok.io/webhooks/miosa")
```

# Known Limitations

URL: https://miosa.ai/docs/known-limitations
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/known-limitations
Source: src/routes/docs/known-limitations/+page.md
Description: An honest list of what doesn't work yet, what's in progress, and what's intentionally out of scope. Updated continuously.

# Known Limitations

We document what doesn't work, on purpose. If you hit something here, it isn't a bug in your code. It is a known gap. For release stages and the roadmap, see [Availability & Roadmap](/docs/availability/); this page lists the concrete gaps and gotchas you can hit today.

Last updated: 2026-10-11. We update this page on every release.

## Sandboxes Public V1

- **Availability is catalog-driven**. A named size, including `xs`, can be selected only when the template catalog and tenant policy admit it. A published contract is not a guarantee of immediate capacity in every environment.
- **The default is `small`**. It resolves to 2 vCPU, 4096 MiB RAM, and 10240 MiB disk. Raw CPU, memory, and disk fields must form a complete exact match for a published contract.
- **Timeouts are bounded**. `timeout_sec` defaults to 3600 and has a maximum of 86400. The extend endpoint replaces the timeout instead of adding duration. `always_on` is policy-dependent.
- **Usage can be incomplete**. Active CPU and network values can be `null` with `measurement_status` set to `unavailable`, or retained with status `stale`. Clients must not treat unavailable values as zero or stale values as current.
- **Snapshots are supported**. Public V1 includes customer-managed snapshot create, list, show, delete, and restore (`/sandboxes/{id}/snapshots` and `/sandboxes/{id}/restore/{snap_id}`), plus pause, resume, and fork.
- **AWS BYOC sandbox capacity is a gated private preview**. Managed and enabled BYOC environments share the sandbox contract, but BYOC placement is unavailable until the customer environment is accepted.
- **No GPU sandboxes**. The public sandbox create contract does not accept, persist, or schedule GPU requests; GPU runtime infrastructure exists behind a feature flag but is not productized, and no GPU rate is billable.
- **No nested virtualization**. KVM and QEMU cannot run inside a sandbox.

## Deployments Phase 3/4 complete; dynamic runtime in hardening

- **Custom domain apex records require ALIAS / ANAME**. DNS providers that do not support flattening, such as GoDaddy, require a workaround.
- **No edge functions yet**. Only origin compute is available.
- **Rollback is per-deployment, not per-route**. You cannot pin one URL path to version 1 and another to version 2 within the same deployment.
- **Containerized deployments publish through Docker Host**. Every sandbox ships Docker with the `docker compose` and `docker buildx` plugins, so you can build and test a container image there. A durable deployment of a containerized app is published through [Docker Host](/docs/docker-host/docker-deploy/); the standard runtime builder builds from source and does not build OCI images into a deployment.
- **Railpack / Nixpacks framework detection** exists but dynamic generation from buildpacks is not complete.
- **Docker Host is a separate runtime path**. It publishes into the workspace Docker Host appliance and proves readiness through the `docker_deploy_app` row, container route, host health, and public URL. Standard MIOSA deployments and Docker Host deployments share the deployment API surface, but they do not use the same runtime substrate.

## Data Services

- **Managed Postgres** Beta. Provisioning lifecycle and credential injection exist. PgBouncer connection pooling and off-box backup drills are in progress.
- **Redis** Beta. Single-node only. Multi-zone replication is planned.
- **Object Storage** Beta. S3-compatible API is live; pre-signed browser uploads work. CDN distribution and geo-replication rollout are operational work in progress.
- **Auth-as-a-Service** Beta. Per-project email/password signup, login, JWT verify, password reset, and email confirmation endpoints are live. Refresh tokens, magic links, OAuth providers, MFA, and passkeys are still planned.
- **Volumes** Beta. Persistent local-backend volumes can be created, attached to computers, detached, deleted, and metered. Local volumes live on one host, so cross-host attach returns an error rather than moving the volume automatically.
- **Usage / audit query views grouped by `external_workspace_id`** have no API view. Raw audit events exist; aggregate them per workspace in your own code.

## Computers (Desktop) GA

- **Headed-only**: no headless mode for Computers. You boot a real Xfce desktop. For headless workloads, use Sandboxes.
- **Browser cookies do not persist** across sessions by default. Use a volume mount or browser profile snapshot to carry cookies across reboots.
- **No multi-monitor virtualization**. Single 1920 × 1080 frame buffer.
- **Audio not exposed**. The stream is video-only; system audio is dropped at the host.

## Computer-Use API

- **No managed agent loop**. You bring your own agent (Anthropic SDK, OpenAI computer-use API, or custom). A built-in `computer.prompt()` convenience will ship when the hosted Optimal session endpoint is publicly available.
- **Approval gating is not enforced server-side**. The approve / reject action protocol is a client-side convention only. Gate sensitive operations in your own agent code.
- **Computer sub-resources** (auto_stop, vnc_credentials, apps, stream_token, metrics, ports, volume attach/detach, clone) have full coverage in the Python SDK. TypeScript, Go, and Java parity is targeted Q3 2026.

## SDKs

| SDK | P1 + P2 resources | P3 / P4 resources | Computer depth |
|---|---|---|---|
| Python | Full | Full | Full |
| TypeScript | Full | Full | Partial |
| Go | Full | Partial | Partial |
| Java | Full | Partial | Partial |
| Elixir | Full | Partial | Partial |

- **Deployment proof parity is still uneven**. CLI, TypeScript SDK, Python SDK, and Go SDK expose proof checks. Java and Elixir proof helpers are still pending.
- **`embeddings`, `provider_defaults`, `benchmarks`, `command_center`, `community`, `email`, `builder_sessions`, `snapshots_standalone`** are Python-only today. Other SDK languages are pending.
- **Python sync client uses long-poll fallback** for streaming events. Use the async client or the TypeScript SDK for proper SSE.
- **Tab-synced language preference** persists in `localStorage`, not your user account. Switching language on one device does not propagate to another.

## API

- **No GraphQL endpoint**. REST + SSE by design.
- **Webhook delivery retries run for roughly 15.5 hours (within a 24-hour window)**. After eight attempts the event is dropped. Use the audit log to backfill missed events.
- **Rate limits**: 60 to 30,000 requests per minute per API key by tier, and 2,500/25,000/100,000 per minute per workspace on Developer/Business/Enterprise. Higher limits are available on request.
- **Browser tokens have a 1-hour default TTL** (60 seconds to 7 days). Refresh server-side; do not attempt client-side extension.
- **One sandbox per browser token**. A single token cannot scope across multiple sandboxes.

## Pricing and Billing

- **No per-tenant usage budgets yet**. You set a workspace cap today; tenant-level caps tied to `external_workspace_id` roll out with the billing attribution extension.
- **All traffic is billable** against the account’s spendable credit balance today. See [Availability & Roadmap](/docs/availability/) for test-mode keys.

## Observability

- **No native log aggregation across workspaces**. Query per-resource today.
- **No OTLP trace export yet**. The `/events` SSE streams provide raw events; bring your own collector.

# Build and deploy a Next.js app

URL: https://miosa.ai/docs/learn/first-production-app
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/learn/first-production-app
Source: src/routes/docs/learn/first-production-app/+page.md
Description: Build a small Next.js app in a Sandbox, preview it, publish it as an immutable Deployment, prove it is live, connect a custom domain, and roll back safely - with the miosa CLI 2.x and the SDKs.

# Build and deploy a Next.js app

This tutorial takes a small Next.js application from an empty Sandbox to a verified production URL.

You will create a Sandbox, write the app, review a temporary Preview, publish an immutable Version, verify the stable Deployment URL, connect `app.example.com`, and learn rollback before you need it.

Publishing does not destroy or convert the Sandbox.
The Sandbox remains a development environment, while the Release and Deployment become independent production resources.

## What you will create

| Resource | Example | Purpose |
|---|---|---|
| Sandbox | `hello-nextjs` | Mutable place to create and test the application. |
| Preview | API-returned temporary URL | Review the live development server before publishing. |
| Deployment | `hello-nextjs` | Stable production identity and version history. |
| Platform URL | API-returned `public_url` | Immediate production access without customer DNS. |
| Custom domain | `app.example.com` | Optional customer-owned hostname attached to the Deployment. |

## Before you start

You need:

- A MIOSA User with access to the intended Organization and Workspace.
- A workspace API key stored only in a server or terminal environment.
- The MIOSA CLI installed (v2.2 or later).
- Permission to create Sandboxes, publish Deployments, and configure domains.
- Access to the DNS provider only if you complete the custom-domain section.

```bash
export MIOSA_API_KEY="msk_u_..."
miosa whoami
```

Confirm that the response identifies the expected Organization and Workspace before creating anything.

Resource IDs are not a substitute for checking the active customer boundary.
If the CLI reports the wrong Organization or Workspace, correct that context before creating the Sandbox or Deployment.

## Step 1: Create the Sandbox

```bash
miosa create hello-nextjs \
  --template nextjs \
  --ttl 1h \
  --wait \
  --json
```

Save the returned Sandbox id:

```bash
export SANDBOX_ID="<sandbox-id>"
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const sandbox = await miosa.sandboxes.create({
  name: "hello-nextjs",
  templateId: "nextjs",
});
console.log(sandbox.id);
```

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sandbox = miosa.sandboxes.create(name="hello-nextjs", template_id="nextjs")
print(sandbox.id)
```

**Expected result:** the Sandbox reaches a usable running state.

If creation remains pending, inspect the returned capacity or readiness reason before retrying.
Do not create repeated Sandboxes while the first request is still progressing.

## Step 2: Create the Next.js application

Scaffold the app inside the Sandbox, then replace `app/page.tsx`.

```bash
miosa exec hello-nextjs --cwd /workspace -- bash -lc 'pnpm create next-app@latest hello-nextjs --typescript --eslint --app --no-tailwind --use-pnpm --yes'
```

Write the page file locally, then copy it into the Sandbox:

```bash
miosa files cp ./page.tsx hello-nextjs:/workspace/hello-nextjs/app/page.tsx
```

Build it:

```bash
miosa exec hello-nextjs --cwd /workspace/hello-nextjs --timeout 300 -- pnpm build
```

```typescript
const page = `export default function Home() {
  return (
    <main style={{ minHeight: "100vh", display: "grid", placeItems: "center" }}>
      <section style={{ textAlign: "center" }}>
        <p style={{ color: "#a1a1aa" }}>Deployed with MIOSA</p>
        <h1 style={{ fontSize: "clamp(3rem, 10vw, 7rem)", margin: 0 }}>Hello from MIOSA</h1>
      </section>
    </main>
  );
}`;

await sandbox.exec.run(
  "cd /workspace && pnpm create next-app@latest hello-nextjs --typescript --eslint --app --no-tailwind --use-pnpm --yes",
);
await sandbox.files.write("/workspace/hello-nextjs/app/page.tsx", page);

for await (const event of sandbox.exec.stream(
  "cd /workspace/hello-nextjs && pnpm build",
)) {
  console.log(event);
}
```

```python
page = '''export default function Home() {
  return (
    <main style={{ minHeight: "100vh", display: "grid", placeItems: "center" }}>
      <h1>Hello from MIOSA</h1>
    </main>
  );
}'''

sandbox.exec.run(
    "cd /workspace && pnpm create next-app@latest hello-nextjs --typescript --eslint --app --no-tailwind --use-pnpm --yes",
)
sandbox.files.write_file("/workspace/hello-nextjs/app/page.tsx", page)

for event in sandbox.exec_stream("cd /workspace/hello-nextjs && pnpm build"):
    print(event)
```

**Expected result:** the build command exits with status `0` and Next.js reports a successful build.

## Step 3: Start and preview the application

Start the server as a background process so it keeps running after the CLI disconnects, then expose port 3000.

```bash
miosa process start hello-nextjs \
  --name web \
  --cwd /workspace/hello-nextjs \
  -- pnpm start --hostname 0.0.0.0 --port 3000

miosa preview create hello-nextjs 3000 --name web --json
```

```typescript
const preview = await sandbox.previews.create(3000);
console.log(preview.url);
```

```python
preview = sandbox.previews.create(port=3000, label="app")
print(preview["url"])
```

Open the exact Preview URL returned by MIOSA.

**Expected result:** the page displays "Hello from MIOSA."

The Preview reflects the current Sandbox process and files.
It can change immediately and can disappear when the Sandbox stops.
The stable production URL is created during publishing.

## Step 4: Publish a Deployment

`miosa deploy create` publishes a new Deployment and makes it live.
Give it the Sandbox as its source, the path the app lives at inside the Sandbox, and the command that serves it.

```bash
miosa deploy create \
  --from-sandbox hello-nextjs \
  --name hello-nextjs \
  --dir /workspace/hello-nextjs \
  --port 3000 \
  --run-command "pnpm start --hostname 0.0.0.0 --port 3000" \
  --wait \
  --json
```

Add `--type docker_deploy` to publish through Docker Host instead of the default runtime.

Save these values from the response:

```bash
export DEPLOYMENT_ID="<deployment-id>"
export PUBLIC_URL="<deployment-public-url>"
```

```typescript
const result = await sandbox.deploy({
  name: "hello-nextjs",
  path: "/workspace/hello-nextjs",
  port: 3000,
  runCommand: "pnpm start --hostname 0.0.0.0 --port 3000",
});

// Read public_url from the response. Do not construct a production hostname.
console.log(result);
```

```python
result = sandbox.deploy(
    name="hello-nextjs",
    path="/workspace/hello-nextjs",
    port=3000,
    run_command="pnpm start --hostname 0.0.0.0 --port 3000",
)

# Read public_url from the response. Do not construct a production hostname.
print(result)
```

Always use the returned `public_url`.
Do not construct a production hostname from the slug, Organization name, or Workspace name.

**Expected result:** the response identifies the Deployment, candidate Release, promoted Version, and `public_url`.

## Step 5: Prove production

A successful build is not enough.
Confirm the Deployment resolved to a live Version and that the public URL answers.

```bash
miosa deploy get hello-nextjs --json
curl --fail --silent --show-error "$PUBLIC_URL" | grep "Hello from MIOSA"
miosa deploy observe hello-nextjs
```

**Expected result:** the Deployment reports a running state with a `public_url`, the public response contains "Hello from MIOSA", and `observe` shows the request.

## Step 6: Connect a custom domain

This step is optional.
The platform URL remains valid while DNS is being configured.

```bash
miosa deploy domain-add hello-nextjs app.example.com
```

MIOSA displays the required DNS record and verification target.
Copy those values exactly into the DNS provider.

For a normal subdomain, the record generally has this shape:

| Type | Host | Value | Proxying |
|---|---|---|---|
| `CNAME` | `app` | The target shown by MIOSA | Disabled until verification completes |

Do not copy `example.com` literally.
Use a hostname controlled by the customer and the target displayed in the live MIOSA domain flow.

Check public DNS, then verify:

```bash
dig app.example.com CNAME +short
miosa deploy domain-verify hello-nextjs <domain-id>
```

**Expected result:** the domain moves through DNS verification, certificate issuance, and routing until HTTPS is active.

An Organization-level deployment domain can generate many application hostnames beneath one parent domain.
An exact custom domain attaches one chosen hostname directly to one Deployment.
Follow the record shown for the domain type you selected.
See [Domains](/docs/docker-host/domains/).

## Step 7: Publish an update safely

Change the heading in `app/page.tsx`, rebuild in the Sandbox, and publish again.

```bash
miosa exec hello-nextjs --cwd /workspace/hello-nextjs --timeout 300 -- pnpm build

miosa deploy create \
  --from-sandbox hello-nextjs \
  --name hello-nextjs \
  --dir /workspace/hello-nextjs \
  --port 3000 \
  --run-command "pnpm start --hostname 0.0.0.0 --port 3000" \
  --wait \
  --json
```

Reusing `--name` targets the existing Deployment, so its identity, stable URL, domains, bindings, and release history are preserved while a new Version is promoted.
Run the proof steps again after the new Version is promoted.

## Step 8: Understand rollback before you need it

List the Deployment versions:

```bash
miosa deploy versions hello-nextjs --json
```

If the new Version is unhealthy, return to the earlier ready one:

```bash
miosa deploy rollback hello-nextjs --to <version-id>
```

Rollback repoints the active Version in seconds without a rebuild.
It does not change the Deployment identity or require a new domain.
See [Rollback](/docs/docker-host/rollback/).

## Common failures and recovery

| Symptom | Likely cause | Safe action | Proof after repair |
|---|---|---|---|
| Sandbox creation remains pending | Requested capacity is not ready or the request is still progressing. | Inspect the readiness reason and wait or select compatible capacity. | The original Sandbox reaches a usable state. |
| Preview returns an error | The Next.js process is stopped, bound to the wrong interface, or using another port. | Start it on `0.0.0.0:3000` with `miosa process start` and recreate the Preview. | The Preview returns "Hello from MIOSA." |
| Publish reports Docker Host is unavailable | The Workspace Docker Host Host is not active. | Confirm the Workspace has an active Docker Host Host, then retry the same `miosa deploy create ... --type docker_deploy`. | Publish returns a Deployment and `public_url`. |
| Build succeeds but the application is not live | Promotion, container health, or routing proof has not completed. | Inspect the publish result and run `miosa deploy get` and `miosa deploy observe`. | The public URL responds with the expected content. |
| DNS remains pending | The record has not propagated, uses the wrong host, or points to the wrong target. | Compare public DNS with the exact record shown by MIOSA and keep proxying disabled during verification. | `miosa deploy domain-verify` reports DNS verified and TLS active. |
| The custom hostname opens another application | The hostname was attached in the wrong Organization or to the wrong Deployment. | Stop and inspect ownership and route bindings before changing DNS again. | The domain resolves to the intended Deployment id and active Version. |
| A new publish causes a regression | The candidate passed build but application behavior is incorrect. | Roll back to the earlier ready Version. | The stable URL serves the previous known-good content. |

## Completion checklist

- [ ] The Sandbox exists in the intended Organization and Workspace.
- [ ] The Next.js production build exits successfully.
- [ ] The Preview displays "Hello from MIOSA."
- [ ] Publishing returns a Deployment id and API-selected `public_url`.
- [ ] The public URL returns the expected content.
- [ ] The custom domain is verified and TLS-active, if configured.
- [ ] An earlier ready Version is identifiable for rollback.
- [ ] The Sandbox can be removed without deleting the Deployment.

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/machines
Source: src/routes/docs/machines/+page.md
Description: What every machine ships with, its sizes, runtimes, and pre-installed tools.

# Machine capabilities

A machine is the compute behind a sandbox or a computer: a versioned template, a named size, a runtime engine, and the tools already installed in the image.
Pick the closest template to your stack, choose a size, and MIOSA boots the machine ready to run your code.

## Templates

A **template** is a prebuilt sandbox image with a specific language, framework, or toolchain already installed.
Pick the closest match to your stack; you can override install/start commands per sandbox if needed.
See [Templates](/docs/develop/templates/) for the built-in images and the custom BuildSpec reference.

## Sizes

Every sandbox runs on a named resource contract.
The default is `small`: 2 vCPU, 4096 MiB RAM, and 10240 MiB disk.
Prefer a named `size` over raw CPU, memory, and disk fields.
See [Sizing and limits](/docs/develop/sandboxes/sizing/) for the contracts and what each costs.

## Runtimes

A sandbox runs on one of two engines: **Firecracker**, MIOSA's long-standing default, or **SOMA**, MIOSA's own open-source VMM.
Your organization chooses which runtimes it offers, and a sandbox records the runtime it was created with.
See [Choosing a runtime](/docs/soma/choosing-a-runtime/) to list the runtimes you can pick and what each reports it supports today.

## Pre-installed tools

Templates ship with their toolchains already in the image, so there is nothing to install before your first command.
Docker with the `docker compose` and `docker buildx` plugins is available in every sandbox, including SOMA runtimes.

https://api.miosa.ai/api/v1/mcp
```

The server speaks MCP 2025-03-26 Streamable HTTP, single-POST JSON-RPC. No SSE listen stream is required.

## OSA

OSA is MIOSA's open-source agent. It runs on your machine or on a MIOSA computer, and works with your Claude or ChatGPT subscription. It is an MCP client, so it takes the MIOSA server as another set of tools next to its built-ins; they appear as `mcp__miosa__*`.

Install OSA (macOS, Linux and Windows), then start it once to run the setup wizard:

```bash
curl -fsSL https://raw.githubusercontent.com/Miosa-osa/OSA/main/scripts/install.sh | sh
osa
```

On Windows use `irm https://raw.githubusercontent.com/Miosa-osa/OSA/main/scripts/install.ps1 | iex`. Homebrew installs the `osagent` binary instead: `brew install Miosa-osa/homebrew-tap/osagent`.

Add MIOSA to `~/.osa/mcp.json` (user scope). The file uses the same `mcpServers` shape as Claude Desktop, and a `url` selects the HTTP transport:

```json
{
  "mcpServers": {
    "miosa": {
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": { "Authorization": "Bearer msk_u_..." }
    }
  }
}
```

Or add it from inside OSA with the slash command, which writes the same file. OSA does not expand environment variables in `headers`, so put the key itself in the value:

```text
/mcp add miosa https://api.miosa.ai/api/v1/mcp -t http -s user -H 'Authorization: Bearer msk_u_...'
```

Run `/mcp` to list servers and their connection status. A project `.mcp.json` also works; OSA asks for approval before it starts a project-scoped server.

## Claude Code

```bash
claude mcp add --transport http miosa \
  https://api.miosa.ai/api/v1/mcp \
  --header "Authorization: Bearer msk_u_..."
```

Add `--scope user` to make it available across all your projects. Verify with `claude mcp list`.

Equivalently, in `.mcp.json` (project) or `~/.claude.json` (user):

```json
{
  "mcpServers": {
    "miosa": {
      "type": "http",
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": { "Authorization": "Bearer msk_u_..." }
    }
  }
}
```

## Codex

`~/.codex/config.toml`:

```toml
[mcp_servers.miosa]
url = "https://api.miosa.ai/api/v1/mcp"
bearer_token_env_var = "MIOSA_API_KEY"
```

`bearer_token_env_var` names the environment variable holding the key, not the key itself. The variable must be present in the environment that launches Codex. The one-line form:

```bash
codex mcp add miosa --url https://api.miosa.ai/api/v1/mcp --bearer-token-env-var=MIOSA_API_KEY
```

## Cursor

`~/.cursor/mcp.json` (global) or `.cursor/mcp.json` (per project):

```json
{
  "mcpServers": {
    "miosa": {
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": { "Authorization": "Bearer msk_u_..." }
    }
  }
}
```

## Hermes

[Hermes Agent](https://github.com/NousResearch/hermes-agent) is Nous Research's open-source agent. MCP support ships with the standard install. Add MIOSA to `~/.hermes/config.yaml`:

```yaml
mcp_servers:
  miosa:
    url: "https://api.miosa.ai/api/v1/mcp"
    headers:
      Authorization: "Bearer ${MIOSA_API_KEY}"
```

Hermes resolves `${MIOSA_API_KEY}` in `url` and `headers` when it connects, from the environment and from `~/.hermes/.env`, so the key stays out of the config file. Put `MIOSA_API_KEY=msk_u_...` in `~/.hermes/.env`, then start `hermes chat`.

## Claude Desktop

Claude Desktop's `claude_desktop_config.json` is stdio only. Use the `mcp-remote` bridge, which launches as a stdio server and proxies to the hosted endpoint.

`~/Library/Application Support/Claude/claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "miosa": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.miosa.ai/api/v1/mcp",
        "--header",
        "Authorization: Bearer ${MIOSA_API_KEY}"
      ],
      "env": { "MIOSA_API_KEY": "msk_u_..." }
    }
  }
}
```

Restart the app (not just reload) after editing. Alternatively, add the hosted URL under Settings, Connectors, Add custom connector and set the Authorization header there.

Prefer the local stdio server (Python package) when you need to wrap the MCP layer with custom local logic, or your client does not support remote MCP. Both modes hit the same MIOSA REST API. See [Install and authenticate](/docs/mcp/install).

## Action authority

Governed MCP tools ask MIOSA's control-plane action authority immediately before dispatch. The control plane owns capability versions, grants, one-time approvals, revocation and receipts. The MCP server only maps tool names to canonical capabilities from a generated contract, and never copies policy locally.

Every registered tool has exactly one canonical capability. A tool with no mapping fails closed before any dispatch. Pending approval, denial, a missing catalog capability, or an unavailable authority all fail closed before the SDK or REST operation runs.

## Active computer

All computer tools accept an optional `computer_id`. When omitted, the server uses the most recently created or accessed computer, so you can `computer_create` once and omit the ID for the rest of the session.

## Errors

Failed tool calls use MCP `isError=true` and include a structured error object that preserves the backend error code, HTTP status, request ID, response details, tool name and a human-readable message. Clients can branch on stable codes such as `INVALID_TENANT_CONTEXT` without parsing display text.

# Advanced MCP setup

This page covers how the MCP server works under the hood, the full client configuration matrix, worked usage examples, troubleshooting, and security guidance. For the install path, see [Install and authenticate](/docs/mcp/install/); for the exact tool list, see the [Tools reference](/docs/mcp/tools/).

## How it works

Diagram:
sequenceDiagram
  participant Editor as Editor (Claude Code / Cursor)
  participant MCP as MIOSA MCP Server
  participant API as MIOSA API
  participant Sandbox

  Editor->>MCP: list_tools()
  MCP-->>Editor: 151 tool definitions
  Editor->>MCP: call_tool("create_sandbox", { name: "build-box" })
  MCP->>API: POST /api/v1/sandboxes
  API->>Sandbox: boot microVM
  API-->>MCP: { id, status }
  MCP-->>Editor: { sandbox_id: "sbx_..." }
  Editor->>MCP: call_tool("exec", { sandbox_id, command: "npm run build" })
  MCP->>API: POST /api/v1/sandboxes/:id/exec
  API-->>MCP: { stdout, stderr, exit_code }
  MCP-->>Editor: stdout + stderr

The MCP server is a thin stateless proxy. Your API key travels with every request; the server never stores credentials.

When a client sends `initialize`, the server returns an `instructions` field containing a workflow guide  -  a compact description of MIOSA resource types, lifecycle conventions, and recommended tool patterns. MCP-aware clients like Claude Code surface this to the model at session start, so the agent understands the platform without requiring extra prompting.

---

## Configuration

### Claude Code

Add to `~/.claude/mcp.json`:

```json
{
  "mcpServers": {
    "miosa": {
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer msk_u_..."
      }
    }
  }
}
```

No local process required. Restart Claude Code and the 145 MIOSA tools appear immediately.

```json
{
  "mcpServers": {
    "miosa": {
      "command": "miosa-mcp",
      "env": {
        "MIOSA_API_KEY": "msk_u_..."
      }
    }
  }
}
```

```json
{
  "mcpServers": {
    "miosa": {
      "command": "npx",
      "args": ["@miosa/cli", "mcp", "serve"],
      "env": {
        "MIOSA_API_KEY": "msk_u_..."
      }
    }
  }
}
```

### Cursor

Open **Cursor → Settings → MCP** and add:

```json
{
  "miosa": {
    "url": "https://api.miosa.ai/api/v1/mcp",
    "headers": {
      "Authorization": "Bearer msk_u_..."
    }
  }
}
```

```json
{
  "miosa": {
    "command": "miosa-mcp",
    "env": { "MIOSA_API_KEY": "msk_u_..." }
  }
}
```

```json
{
  "miosa": {
    "command": "npx",
    "args": ["@miosa/cli", "mcp", "serve"],
    "env": { "MIOSA_API_KEY": "msk_u_..." }
  }
}
```

### Windsurf

In `~/.codeium/windsurf/mcp_config.json`:

```json
{
  "mcpServers": {
    "miosa": {
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer msk_u_..."
      }
    }
  }
}
```

```json
{
  "mcpServers": {
    "miosa": {
      "command": "miosa-mcp",
      "env": {
        "MIOSA_API_KEY": "msk_u_..."
      }
    }
  }
}
```

```json
{
  "mcpServers": {
    "miosa": {
      "command": "npx",
      "args": ["@miosa/cli", "mcp", "serve"],
      "env": {
        "MIOSA_API_KEY": "msk_u_..."
      }
    }
  }
}
```

Reload Windsurf. Tools are available in the Cascade panel.

### Environment variable reference (local server only)

| Variable | Required | Default | Description |
|---|---|---|---|
| `MIOSA_API_KEY` | Yes |  -  | Your `msk_u_...` key |
| `MIOSA_API_URL` | No | `https://api.miosa.ai` | Override for self-hosted or staging |
| `MIOSA_DEFAULT_TEMPLATE` | No | `miosa-sandbox` | Template used when `sandbox_create` omits `template_id` |
| `MIOSA_TIMEOUT_MS` | No | `30000` | Per-request HTTP timeout in milliseconds |
| `MIOSA_LOG_LEVEL` | No | `warn` | `debug`, `info`, `warn`, `error` |

---

## Usage examples

### Create a computer and take a screenshot

```
You: Create a Linux desktop and take a screenshot of whatever is on screen.
```

The assistant calls `computer_create({ template_type: "miosa-desktop", size: "small" })`, waits for it to boot, calls `desktop_screenshot()`, and describes what it sees. It can then call `desktop_click`, `desktop_type`, and `desktop_launch` to interact.

---

### Deploy a sandbox to production

```
You: Build the Next.js app in the sandbox and deploy it to a permanent URL.
```

The assistant calls `sandbox_exec({ command: "npm run build" })`, confirms `exit_code: 0`, then calls `deployment_publish({ sourceSandboxId: "sbx_...", kind: "static", outputPath: "/workspace/.next/out" })` and returns the live URL.

---

### Set up a cron job

```
You: Create a cron job that runs a health check script every 5 minutes.
```

The assistant calls `cron_create({ name: "health-check", schedule: "*/5 * * * *", command: "bash /workspace/health-check.sh", computer_id: "computer_..." })`. To trigger it immediately for a smoke test, it calls `cron_run_now({ cron_id: "cron_..." })`.

---

### Create a database and get credentials

```
You: Provision a Postgres database and give me the connection string for my app.
```

The assistant calls `database_create({ name: "my-app-db", region: "us-east" })`, polls `database_get` until status is `running`, then calls `database_credentials({ id: "db_..." })` and returns the connection string. It can also call `deployment_env_set` to inject `DATABASE_URL` directly into a deployment.

---

## Troubleshooting

Set `MIOSA_LOG_LEVEL=debug` to see every request and response the MCP server sends to the MIOSA API. Useful for diagnosing auth or timeout issues.

**`401 Unauthorized` on hosted MCP**  -  Confirm the `Authorization` header value starts with `Bearer msk_u_` (not just the key alone). Check that the key is active under Dashboard → Settings → API Keys.

**`MIOSA_API_KEY is not set` (local server)**  -  The env var is missing from your MCP config. Confirm the `env` block is present in your client's MCP JSON and that the key starts with `msk_u_`.

**Tool calls timeout**  -  Sandbox boots take 2-8 s on first call. Increase `MIOSA_TIMEOUT_MS` if your client has a short MCP timeout. Claude Code default is 30 s; Cursor default is 10 s.

**`403 Forbidden`**  -  Your key is valid but lacks the required scope. Check [API Keys](/docs/platform/api-keys/) to confirm the key has the scopes needed for the tools you're calling.

**`No tools appear in Cursor`**  -  Cursor requires the MCP config to be valid JSON. Run `node -e "JSON.parse(require('fs').readFileSync('cursor-mcp.json','utf8'))"` to validate.

---

## Security considerations

- Store `MIOSA_API_KEY` in your client's secret store, not in a `.env` file committed to git.
- Use a **scoped key** for MCP: grant only the scopes your workflow needs. Never use an admin key for editor integrations.
- The hosted MCP endpoint and local MCP server both make outbound HTTPS requests only. Neither opens inbound ports.
- Resources created through MCP are subject to the same tenant-scoped authorization as direct API calls. The MCP server cannot access another tenant's resources.

# Tool server catalog

URL: https://miosa.ai/docs/mcp/catalog
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/mcp/catalog
Source: src/routes/docs/mcp/catalog/+page.md
Description: Add an official tool server in one step, test its key before saving, and keep the key in the workspace vault.

MIOSA keeps a catalog of official tool servers you can add in one step, then attach to your agents.
Open it from **Connections**, then **Tool servers**, then **Browse catalog**.

## What is in the catalog

The catalog lists 40 verified tool servers, including Apify, GitHub, Linear, Notion, Sentry, Stripe, Cloudflare, Firecrawl, Exa, Perplexity, Context7, and Playwright.

Search by name, or filter by category.
Each entry shows what the vendor needs and where to get it.

Some servers only sign in through your browser, for example Figma, Vercel, Google Workspace, and Mobbin.
They are listed, with no key field, and are not available yet.

## Add a key and test it

Adding a server asks for exactly the keys the vendor needs, each with a "Get it here" link.
Before anything is saved, **Test connection** checks the key against the vendor.
The key is sent only to the vendor's own URL, and the test stores nothing.

On success the key is sealed in the workspace vault, and the saved server holds a `{{secret:NAME}}` reference, never the value.
A response never carries a key.

If the name is already taken, you get a clear conflict, and you can add a second account with its own name.

## Which harnesses load tool servers today

A tool server is loaded by the harness whose CLI reads a tool-server config.
Today that is Claude Code, Codex, and OSA.
The generic harnesses, pi, OpenCode, Prime Agent, Kimi Code, and Mistral Vibe, do not load tool servers yet.

## The catalog as an API

| Route | Scope | What it does |
|---|---|---|
| `GET /api/v1/mcp-catalog?workspace_id=` | `connections:read` | Lists entries, categories, and what you already added |
| `POST /api/v1/mcp-catalog/:slug/test` | `connections:write` | Tests a key against the vendor's URL, and stores nothing |
| `POST /api/v1/mcp-catalog/:slug/install` | `connections:write` | Adds the server and seals its keys in the workspace vault |

Install sends `{ workspace_id, method, name, values }` and returns `201` with the server and the secret names, never a value.
A duplicate returns `409 ALREADY_ADDED`.
A bad field returns `422 VALIDATION_ERROR` with details per field.

# Install and authenticate

URL: https://miosa.ai/docs/mcp/install
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/mcp/install
Source: src/routes/docs/mcp/install/+page.md
Description: Choose the hosted MIOSA MCP endpoint or the local stdio package, create a key, and set organization context.

There are two ways to run the MIOSA MCP server. Both hit the same MIOSA REST API. The only difference is whether the JSON-RPC bridge runs in MIOSA's infrastructure (hosted) or on your machine (stdio).

## Hosted (recommended)

No install. Point any MCP client at the public endpoint with your key as a Bearer token.

```text
https://api.miosa.ai/api/v1/mcp
```

```bash
claude mcp add --transport http miosa \
  https://api.miosa.ai/api/v1/mcp \
  --header "Authorization: Bearer msk_u_your_key_here"
```

See the [overview](/docs/mcp) for the config file form for Claude Code, Codex, Cursor and Claude Desktop.

## Local stdio

Use stdio when you need to wrap the MCP layer with custom local logic, or your client does not support remote MCP.

```bash
pip install miosa-mcp
```

Requires Python 3.10 or newer. Package version 0.4.3.

The standalone package registers its own tool set and its own names: 194 tools with the prefix-first scheme (`sandbox_create`, `sandbox_exec`, `computer_create`). It is a separate server from the hosted endpoint, which registers 151 tools with a different scheme (`create_sandbox`, `exec`, `computer_create`). The [tools reference](/docs/mcp/tools) documents the hosted server; the local package's tool names follow the same pattern as its own `list_tools` output.

Add to `~/.claude/mcp.json`:

```json
{
  "mcpServers": {
    "miosa": {
      "command": "python",
      "args": ["-m", "miosa_mcp"],
      "env": {
        "MIOSA_API_KEY": "msk_u_your_key_here",
        "MIOSA_TENANT": "optional-organization-slug"
      }
    }
  }
}
```

## Connect OSA

OSA is MIOSA's open-source agent. It runs on your machine or on a MIOSA computer, and works with your Claude or ChatGPT subscription. It reads MCP servers from `~/.osa/mcp.json`, so the hosted endpoint is a `url` plus an `Authorization` header there. The full setup, including the `/mcp add` command, is in the [overview](/docs/mcp#osa).

```json
{
  "mcpServers": {
    "miosa": {
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": { "Authorization": "Bearer msk_u_your_key_here" }
    }
  }
}
```

## Connect Hermes

Hermes Agent reads `mcp_servers` from `~/.hermes/config.yaml` and resolves `${MIOSA_API_KEY}` from `~/.hermes/.env`. See the [overview](/docs/mcp#hermes) for the block.

## Install or serve from the CLI

The `miosa` CLI can configure or run the MCP server for you, so you do not have to edit a client config by hand.

```bash
miosa mcp install                                  # Claude Code, user scope
miosa mcp install --client cursor                  # Cursor
miosa mcp install --client gemini                  # Gemini CLI
miosa mcp install --client claude --scope project  # a shared .mcp.json
miosa mcp install --print                          # show the change, write nothing
```

`miosa mcp install` does not write OSA or Hermes config; use the two sections above for those. It writes the hosted endpoint and your API key into the client's config file, keeping the other servers it already lists. It takes `--client` (`claude`, `cursor`, `gemini` or `manual`), `--name` (default `miosa`), `--scope` (`user` or `project`, for Claude), `--url`, `--force` and `--print`.

For clients that need a stdio server, run the bridge over standard input:

```bash
miosa mcp serve
```

`miosa mcp serve` reads newline-delimited JSON-RPC 2.0 messages, forwards each to MIOSA MCP, and writes one JSON line per response. Point a client at it with:

```json
{
  "mcpServers": {
    "miosa": {"command": "miosa", "args": ["mcp", "serve"]}
  }
}
```

List the tools the server exposes:

```bash
miosa mcp tools
```

`miosa mcp serve` and `miosa mcp tools` both take `--url` (default: the API base URL plus `/mcp`). The Python package also exposes a `miosa-mcp` entry point for the same stdio role.

See [Advanced MCP setup](/docs/mcp/advanced/) for the per-client configuration matrix, the environment variable reference (local server only), and troubleshooting.

## Get a key

Create a user API key at [miosa.ai/dashboard/api-keys](https://miosa.ai/dashboard/api-keys). It looks like `msk_u_<hex>`. Treat it like a password.

From the CLI:

```bash
miosa api-key create mcp-key --preset agent
miosa api-key create mcp-key --preset agent --quiet-key   # print only the secret
```

## Organization context

The hosted endpoint scopes every request to the organization that owns the API key, so there is no organization-switch tool there. The local stdio package (`miosa-mcp`) is the one that registers organization helpers and reads `MIOSA_TENANT` for an initial organization:

```text
organization_list()                       # organizations available to you
organization_current()                    # the organization in use
organization_switch(organization="acme")  # switch by UUID or slug
```

These tools belong to the local package, not the hosted server; the [tools reference](/docs/mcp/tools) lists the hosted tools.

The key is checked by the same auth plug that protects every REST endpoint, so the MCP surface inherits tenant scoping, plan limits, credit checks and audit logging.

## Verify

```bash
claude mcp list
```

You should see `miosa` with a connected status. If a call returns `401`, the key is invalid, expired or revoked. A `429` means you hit the plan's rate limit (same limit as the REST API; the window is per minute).

You can also list the catalogue over the wire:

```bash
curl -sS -X POST https://api.miosa.ai/api/v1/mcp \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer msk_u_your_key_here" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list","params":{}}' | jq .
```

# Moving from Railway

URL: https://miosa.ai/docs/migrate/railway
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/migrate/railway
Source: src/routes/docs/migrate/railway/+page.md
Description: Bring a Railway project to MIOSA with one reviewed plan, every environment in its own Deploy target, services created stopped, and an exact list of what carries over and what you finish by hand.

# Moving from Railway

`miosa import railway` reads a Railway project through Railway's public API and writes a plan.
The plan lists the MIOSA project, one Deploy target per Railway environment, and in each target the services, databases, variable names and shared variables it would create.
It also lists everything it cannot carry across.
Nothing is created until you review the plan and apply it, and an apply starts nothing unless you ask.

This page is the reference for what carries over, what does not, and what to do about the secrets.

## Before you start

- A Railway token: an account, workspace or project token from Railway's account settings.
  `--project` takes the project's id, or its name when the login can list it; if Railway refuses, the import prints Railway's message and asks for the id.
  MIOSA reads it, never stores it, and never writes it to the plan.
  If you are logged in with the Railway CLI, `--via railway-cli` reads through that session instead, so no token passes through MIOSA.
- The MIOSA CLI, `@miosa/cli` 2.13.4 or newer:

```bash
npm install -g @miosa/cli
miosa --version
```

- GitHub connected to MIOSA, when your services build from GitHub repositories:

```bash
miosa connections add apps github
```

- Assume every secret in the Railway project is compromised.
  Railway disclosed on 2026-10-21 that its secrets were exposed, so the import copies names, not values, unless you explicitly ask otherwise.

## The steps

```bash
export RAILWAY_TOKEN=...                                          # or --token-file, or a prompt
miosa import railway --project acme-api --environment all         # review only; nothing is created
miosa import railway --project acme-api --environment all --out plan.json
miosa import railway --apply --plan plan.json --region us-east    # creates everything, stopped
miosa service vars set acme-api api STRIPE_KEY=<new value> --deploy-target production
miosa service deploy acme-api api --deploy-target production
```

`--environment` takes one environment, several (`production,staging`), or `all`.
The default is `production`.

The review prints what will be created in each Deploy target, where each setting came from, which variables need a value, and a "Finish by hand" list with the next step for each item.
Every field that cannot be carried appears there; nothing is dropped silently.

## What apply does

- It creates the project, then one Deploy target per Railway environment, reusing a target that already exists.
- It creates every service in the Deploy target of its environment, so `production` and `development` keep separate services, variables and settings.
- It creates every service **stopped**.
  Nothing builds or runs until you deploy it with `miosa service deploy`, or apply with `--deploy`.
- `--deploy` starts every service that has a source, after the GitHub copies are ready.
  It refuses while any variable has no value, so a service never starts with an empty secret.
- It does **not** attach custom domains unless you pass `--attach-domains`.
  Attaching a live domain during the import would move its traffic before the MIOSA services run.
  Without the flag, the review lists each domain as skipped and the summary prints the command that attaches it later.
- It links a GitHub repository, private or public, through your GitHub connection.
  MIOSA copies the repository into Forge and builds from the copy, so no credential is stored on the service.
- It checks everything before creating anything.
  If GitHub is not connected, it stops with `Connect GitHub first: miosa connections add apps github`.
  If your connection cannot read a repository, it names the repository and stops.
  If your organization cannot build services from a repository yet, it says so and stops.
  In each case nothing is created.
- Running apply again creates only what is missing: every project, Deploy target and service is looked up first.
- It gives every service a name and slug MIOSA accepts.
  A package name such as `@acme/web` becomes `acme-web`, and references to it follow.
  A slug longer than 40 characters is shortened with a short hash of the name, the same on every run.

## What carries over

| Railway | MIOSA |
|---|---|
| Project | Project |
| Environment | A Deploy target of the same name, with its own services and variables |
| Service | Web service, Worker or Schedule, in its environment's Deploy target |
| Repository, branch, root directory | The service source; a GitHub repository is linked through your GitHub connection |
| Dockerfile path | `source.dockerfile`, relative to the root directory |
| Build command | `source.build_command` |
| Start command | `start_command` |
| Pre-deploy command (for example `alembic upgrade head`, `drizzle-kit migrate`) | `pre_deploy_command` |
| Health check path and timeout | `healthcheck_path` and `healthcheck_timeout_s` |
| Restart policy and retries | `restart_policy` and `max_retries` |
| Replicas | `replicas` (1 to 50) |
| Cron schedule | A Schedule service |
| `railway.json`, `railway.toml` | Read from the repository through Railway; the file wins over the service settings, as on Railway |
| Variables | Names, build-visible as on Railway; `${{Service.VAR}}` references, rewritten where MIOSA's names differ |
| Shared variables | Shared variables of the same Deploy target (names) |
| Postgres, Redis, MySQL template images and plugins | A database service with a managed database |
| Domain target port | The service port, which the health check and the public address use |
| Custom domains | Listed; attached with `--attach-domains`, and served from MIOSA once their DNS points here |

Each setting is taken from the first place that has it: the repository's config file, then the service settings, then what the latest deployment ran.
The plan records which one, for every setting.

### References

MIOSA uses the same `${{Service.NAME}}` reference syntax as Railway.
The import rewrites the names that differ:

| Railway reference | Becomes |
|---|---|
| `${{Redis.REDISHOST}}`, `REDISPORT`, `REDISPASSWORD` | `${{Redis.REDIS_HOST}}`, `REDIS_PORT`, `REDIS_PASSWORD` |
| `${{Redis.REDISUSER}}` | `default` |
| `${{Redis.REDIS_URL}}` | unchanged |
| `${{Postgres.POSTGRES_USER}}`, `POSTGRES_PASSWORD`, `POSTGRES_DB` | `${{Postgres.PGUSER}}`, `PGPASSWORD`, `PGDATABASE` |
| `${{Postgres.DATABASE_URL}}`, `PGHOST`, `PGPORT`, `PGUSER`, `PGPASSWORD`, `PGDATABASE` | unchanged |
| `${{api.RAILWAY_PRIVATE_DOMAIN}}` | `${{api.MIOSA_PRIVATE_DOMAIN}}` (`api.miosa.internal`) |
| `RAILWAY_SERVICE_NAME`, `RAILWAY_SERVICE_ID`, `RAILWAY_ENVIRONMENT_NAME`, `RAILWAY_ENVIRONMENT_ID`, `RAILWAY_PROJECT_ID`, `RAILWAY_PROJECT_NAME`, `RAILWAY_REGION` | the `MIOSA_` name |

A service is unreachable by its private domain on MIOSA today, because private networking between services is off.
The review flags every variable that reaches another service that way; point it at an address MIOSA can reach (for SMTP, your mail provider).

A reference with no MIOSA equivalent, such as `RAILWAY_PUBLIC_DOMAIN`, `REDIS_PUBLIC_URL` or `DATABASE_PUBLIC_URL`, is listed in the review.
That variable is created without a value, and you set it after the import.

Railway's own variables (`RAILWAY_*`) are not imported; MIOSA injects its own `MIOSA_*` names.

### Build-visible variables

Railway exposes every service variable to the build, so a framework inlines `NEXT_PUBLIC_*`, `VITE_*` and `PUBLIC_*` values when it builds.
The import keeps that: every imported variable and shared variable is created build-visible, and the review says how many.
`MIOSA_*` and `RAILPACK_*` names stay runtime only, because MIOSA reserves them.
A variable created without a value becomes build-visible when you set it with `--build`; the summary prints that command.

On MIOSA a build-visible variable reaches the build as a BuildKit secret, so it is never stored in an image layer.
The exception is a Dockerfile that declares an `ARG` of the same name: that variable is passed as a build argument, as on Railway, and a `RUN` step that uses it is recorded in the image history.

To create every variable runtime only, pass `--runtime-only-vars` when you write the plan.
You can change one later:

```bash
miosa service vars set <project> <service> NEXT_PUBLIC_API_URL=https://api.example.com --build
miosa service vars set <project> <service> STRIPE_KEY=<new value> --no-build
```

## What does not carry over

| Railway | What to do |
|---|---|
| Variable values | Set new values on MIOSA; see below |
| Region outside the US (for example `asia-southeast1`, `europe-west4`) | MIOSA runs in `us-east`, `us-west` and `us-mia`; the review lists every such service and apply needs `--region` |
| Builder (Nixpacks) | MIOSA builds the Dockerfile if the repository has one, else detects the stack with Railpack; check the first build |
| Watch patterns | MIOSA builds on every push; the review lists them |
| Sleep on idle | Not carried; set the `sleep` setting after the import |
| Database data and volume contents | Not copied; the review lists each volume and its size, and you move the data |
| Service volumes | Listed with the `miosa volume create` command and the mount path to attach |
| `*.up.railway.app` domains | Railway-owned DNS; MIOSA assigns `<label>.<org>.miosa.app` |
| A service uploaded with the Railway CLI (no repository or image) | Created without a source; upload the code with `miosa service deploy <project> <service> --dir <path>` |
| MongoDB plugins | Create a MongoDB database with `miosa db create --engine mongodb` |

## Rotate the secrets

Apply refuses to run while a variable has no value, unless you pass `--allow-missing-values`, which creates those variables empty.
Services stay stopped either way, so nothing starts with a missing or leaked secret.

1. Assume every secret in the Railway project is compromised.
2. Do not copy values during the import; set new ones on MIOSA.
3. Rotate at the provider first (database password, Stripe, SMTP, API keys), then paste the new value into MIOSA.
4. Deploy after the new values are set.
5. Delete the old Railway project once the MIOSA one serves traffic.

```bash
miosa service vars set <project> <service> STRIPE_KEY=<new value> --deploy-target production
miosa project vars set <project> APP_NAME=<value> --deploy-target production
miosa service deploy <project> <service> --deploy-target production
```

`--copy-variables` exists for a test project where nothing is sensitive.
It prints the same warning, and it is never the default.

## If you only have a config file

`--from-file` reads a `railway.json` or `railway.toml` locally, with no token and no network call:

```bash
miosa import railway --from-file ./railway.toml --service-name api
```

The plan has no source, because a config file has none; add one to the plan before you apply.

## Undo

Every id the apply creates is recorded as it is created.

```bash
miosa import railway --cleanup --state .miosa/import-railway-acme-api.json --yes
```

`--cleanup` prints exactly what it will delete first, and deletes only those ids.
An interrupted apply continues with `--resume`.

## Railway terms, MIOSA names

| Railway says | MIOSA calls it |
|---|---|
| Project | Project |
| Environment | Deploy target |
| Service | Service (Web service, Worker, Private service, Schedule) |
| Plugin, database template | Database service |
| Deploy | Release |
| Variables | Variables |
| Shared variables | Shared variables |
| Volume | Volume |
| Domain | Public address or custom domain |

# Moving from Vercel

URL: https://miosa.ai/docs/migrate/vercel
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/migrate/vercel
Source: src/routes/docs/migrate/vercel/+page.md
Description: Import a Vercel project with miosa import vercel, review the plan, and what carries over.

# Moving from Vercel

`miosa import vercel` reads a Vercel project's `vercel.json` and writes a plan.
The plan names the MIOSA project, the `production` environment, one service, and the environment variable names the file declares.
Review the plan, then apply it.
Nothing is created until you apply.

## Import a project

```bash
npm i -g @miosa/cli
miosa import vercel --from-file vercel.json --name shop --repo https://github.com/acme/shop
miosa import vercel --from-file vercel.json --out plan.json
miosa import vercel --apply --plan plan.json
```

| Flag | Meaning |
|---|---|
| `--from-file` | The `vercel.json` to read |
| `--name` | The MIOSA project name |
| `--service` | The service name inside the project (default `web`) |
| `--repo` | The Git URL of the service's source |
| `--region` | `us-east`, `us-west` or `us-mia`; overrides the file |
| `--into` | Import into an existing MIOSA project |
| `--apply` | Create what the plan says |
| `--resume` | Continue an interrupted apply |

## What carries over

| Vercel | MIOSA |
|---|---|
| The app | A [service](/docs/services/overview) built from the repository |
| Region | The service region, when the file names one MIOSA has |
| Environment variable names | [Variables](/docs/services/variables) with no values |

Values are never copied.
Set each value on the service, then deploy.

## What does not carry over

The plan lists each of these with the reason: rewrites, redirects, headers, builds, the `functions` block, `cleanUrls`, `trailingSlash`, `buildCommand`, `installCommand`, `outputDirectory` and `crons`.
Recreate what you need as [service settings](/docs/services/services).

# Migrating from miosa-sandbox

URL: https://miosa.ai/docs/migrating-from-miosa-sandbox
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/migrating-from-miosa-sandbox
Source: src/routes/docs/migrating-from-miosa-sandbox/+page.md
Description: Move off the deprecated @miosa/sandbox, miosa-sandbox, and sandboxes-go packages onto the canonical MIOSA SDKs.

# Migrating from miosa-sandbox

The standalone sandbox packages are deprecated compatibility wrappers. Each one now delegates to the canonical MIOSA SDK, so the fastest migration is often to install the canonical package and change one import.

| Deprecated package | Canonical replacement |
|---|---|
| `@miosa/sandbox` (JavaScript) | `@miosa/sdk` |
| `miosa-sandbox` (Python) | `miosa` |
| `sandboxes-go` (Go) | `github.com/Miosa-osa/miosa-go/v2` |

## JavaScript

```bash
npm install @miosa/sdk
```

```typescript
// Before

const client = new MIOSA({ apiKey: process.env.MIOSA_API_KEY! });

// After

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
```

`@miosa/sandbox` re-exports the canonical client, so it keeps installing while you migrate, but new code should import `@miosa/sdk` directly. The renamed classes map as:

| Old import | Canonical replacement |
|---|---|
| `MIOSA` | `Miosa` |
| `SandboxClient` | `Sandboxes` |
| `ComputerClient` | `Computers` |
| `CreateSandboxOptions` | `SandboxCreateParams` |
| `CreateComputerOptions` | `ComputerCreateParams` |

## Python

```bash
pip install miosa
```

```python
# Before
from miosa_sandbox import MIOSA
with MIOSA(api_key="msk_...") as client:
    with client.sandboxes.create() as sandbox:
        print(sandbox.exec("python3 -c 'print(1 + 1)'").stdout)

# After
from miosa import Miosa
with Miosa(api_key="msk_...") as client:
    with client.sandboxes.create() as sandbox:
        print(sandbox.exec("python3 -c 'print(1 + 1)'").stdout)
```

`MIOSA` and `AsyncMIOSA` are preserved in the compatibility package and return the canonical `miosa` resource classes; the async class becomes `AsyncMiosa`.

## Go

```bash
go get github.com/Miosa-osa/miosa-go/v2
```

```go
// Before

client, _ := sandboxes.New(sandboxes.Config{APIKey: os.Getenv("MIOSA_API_KEY")})

// After

client := miosa.NewClient("msk_...")
```

The `sandboxes-go` package receives bug fixes but no new features, with a sunset date of 2026-11-08. The JavaScript and Python compatibility packages exist only so older integrations keep installing while they migrate.

## Behavior differences to expect

- **One client, one surface.** In the canonical SDKs, sandboxes live on the client (`client.sandboxes`) alongside computers, files, snapshots, and agent runs. Code that reached for a separate sandbox client now goes through the single client.
- **Ownership selectors are first-class.** `workspace_id`, `project_id`, and `external_user_id` can be passed directly on create, and are exposed on the returned handle.
- **`size` and `resource_contract`.** When no size is supplied, the compatibility packages request the canonical `small` contract: 2 vCPU, 4096 MiB memory, and 10240 MiB disk. The response exposes `size`, `resource_contract`, and `usage()` on both sync and async handles.
- **Canonical names.** Use `client.sandboxes` on the sandbox image, `client.computers` with `miosa-desktop`, and `client.dockerDeploy` for the Docker Host appliance. `computer` is the user-facing product name; `miosa-desktop` is the template it boots from.

## Verify the migration

The compatibility packages and the canonical SDKs hit the same API, so the check is behavioral:

```python
from miosa import Miosa

with Miosa(api_key="msk_...") as client:
    sbx = client.sandboxes.create(template_id="miosa-sandbox", size="small")
    print(sbx.state, sbx.resource_contract)
    print(sbx.exec("python3 -c 'print(1 + 1)'").stdout)   # 2
    sbx.destroy()
```

If that prints `2` and a `small` contract, the migration is complete.

# OpenComputers

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers
Source: src/routes/docs/opencomputers/+page.md
Description: Connect machines you already own to MIOSA and manage them as hosts - commands, containers, meshes, GitHub Actions runners, backups, tunnels, and devices.

# OpenComputers

**OpenComputers** connects machines you already own to MIOSA.
You install the MIOSA host agent on a workstation, a GPU box, an on-premises server, or an existing server at a hosting provider.
The agent opens an authenticated outbound session, and MIOSA then manages that machine as a **host**.

A host is a machine in your organization.
You keep the hardware, the operating system, and the decision about what the agent may reach.
MIOSA supplies identity, authorization, orchestration, and the remote-operation surface: commands, containers, private networks, CI runners, scheduled backups, tunnels, and agent work.

A **host** is one enrolled machine. An **OpenComputer** is that machine as a MIOSA resource - the term used in the UI and in the [OpenComputers API](/docs/api-reference/open-computers/). A **device** is any runtime MIOSA can run a command on, including a sandbox or a managed Computer.

## When to use OpenComputers

Choose OpenComputers when the work must run on hardware you control, or when you already have the capacity.

| You need | Use | Why |
|---|---|---|
| Run on hardware you already own or rent | OpenComputers | The agent runs the command on that exact machine, inside its OS permissions. |
| A desktop or browser session you can stream | [Managed Computer](/docs/computers/overview/) | Provisioned and operated by MIOSA, with a ready desktop contract. |
| Isolated, disposable code execution | [Sandboxes](/docs/develop/sandboxes/) | A fresh microVM per sandbox, no host to maintain. |
| A governed worker pool inside your own AWS account or Google Cloud project | [BYOC](/docs/infrastructure/byoc/overview/) | A separate onboarding path for cloud worker capacity. |

The same MIOSA interface does not mean every host supports every operation.
Direct execution on a host runs as the host user, and a host only advertises the capabilities its agent reports.
Select the host explicitly and check the capability your workflow needs.

## What MIOSA manages

| Layer | Who operates it |
|---|---|
| Host, operating system, disks, power, network | You, or your hosting provider |
| Host agent service and its OS user and permissions | You install and run it; MIOSA delivers signed agent updates |
| Organization, API, authorization, orchestration, audit | MIOSA |
| Local files, services, and credentials the agent can reach | You, bounded by the agent user's permissions |
| Commands, status, output, artifacts, desktop streams, model requests | May pass through MIOSA as part of the workflow |

Connecting a host does not install the MIOSA platform on your premises, and it does not turn the host into a sandbox worker pool, an Docker Host host, or a BYOC region.
See [Shared responsibility](/docs/infrastructure/shared-responsibility/) for the full boundary matrix.

## The OpenComputers surface

| Area | What you get | Guide |
|---|---|---|
| Hosts | Enroll machines, inspect status, capabilities, metrics, services, and jobs | [Hosts and capabilities](/docs/opencomputers/hosts/) |
| Commands and files | Run a command on one host, or on every member of a group; read and write files | [Hosts and capabilities](/docs/opencomputers/hosts/) |

| Apps, clusters, groups, secrets | Install catalog apps, serve a model across hosts, target groups, scope secrets | [Hosts and capabilities](/docs/opencomputers/hosts/) |

## Connect a host

```bash
miosa host register studio --platform linux   # prints the host key once
miosa host list
miosa host get <host>
```

`register` creates the host record and prints the **host key** exactly once.
Give that key to the agent on the machine; it is not the same credential as your platform API key.

Follow [Connect your first host](/docs/opencomputers/connect/) for the install, enrollment, and verification walkthrough.

# Backups and snapshots

URL: https://miosa.ai/docs/opencomputers/backups
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/backups
Source: src/routes/docs/opencomputers/backups/+page.md
Description: Schedule directory backups on your own hosts, keep a rolling snapshot history, and restore a snapshot onto the same host or a different one.

# Backups and snapshots

A backup configuration names one directory on one host, a schedule, and a retention policy.
Each run produces a snapshot, and a snapshot can be restored onto any host in your organization.

This is the backup path for machines you own. Managed sandboxes and computers use their own [snapshots](/docs/api-reference/snapshots/).

## Create a backup configuration

```bash
miosa host backup list <host>
miosa host backup new <host> --name nightly --path /data --schedule "0 3 * * *" --keep 7
miosa host backup new <host> --name logs --path /var/log --schedule "0 * * * *" --compression 6 --exclude "*.tmp"
```

Aliases: `miosa host backups`, and `create` for `new`.

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/backup-configs" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"nightly","path":"/data","schedule_cron":"0 3 * * *","timezone":"UTC","retention_count":7}'
```

| Field | Type | Required | Description |
|---|---|---|---|
| `name` | string | Yes | 1 to 100 characters; unique per host |
| `path` | string | Yes | Directory on the host to back up, up to 1024 characters |
| `schedule_cron` | string | No | Cron expression, parsed and validated when the configuration is saved |
| `timezone` | string | No | Timezone the schedule is read in; default `UTC` |
| `retention_count` | integer | No | How many snapshots to keep, 1 to 365 |
| `retention_days` | integer | No | How many days to keep snapshots, 1 to 3650 |
| `exclude_patterns` | string[] | No | Globs to exclude |
| `compression_level` | integer | No | 1 to 22; default 19 |

A configuration is `active` or `paused`.
`last_snapshot_at` and `last_snapshot_size_bytes` record the most recent run.

## Run and manage schedules

```bash
miosa host backup trigger <host> nightly
miosa host backup pause <host> nightly
miosa host backup resume <host> nightly
miosa host backup update <host> nightly --schedule "0 4 * * *"
miosa host backup rm <host> nightly --yes
```

| Action | REST |
|---|---|
| Trigger now | `POST .../backup-configs/{config_id}/trigger` |
| Pause | `POST .../backup-configs/{config_id}/pause` |
| Resume | `POST .../backup-configs/{config_id}/resume` |
| Update | `PATCH .../backup-configs/{config_id}` |
| Delete | `DELETE .../backup-configs/{config_id}` |

A trigger returns `202` with the new snapshot while the upload is still running.
Triggering a backup on a host that is not connected returns `503`.

## Snapshots

```bash
miosa host backup snapshot list <host> nightly --limit 10
miosa host backup snapshot list <host> nightly --before 2026-09-01T00:00:00Z
miosa host backup snapshot get <snapshot>
miosa host backup snapshot rm <snapshot> --yes
```

Aliases: `miosa host backup snapshots`.

```bash
curl --fail-with-body -sS \
  "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/backup-configs/$CONFIG_ID/snapshots?limit=10" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

| Snapshot field | Meaning |
|---|---|
| `id` | Snapshot ID, used by every snapshot route |
| `config_id` | The configuration that produced it |
| `host_id` | The host it was taken from |
| `state` | `uploading`, `complete`, `failed`, or `expired` |
| `total_bytes` | Uncompressed size |
| `compressed_bytes` | Stored size |
| `chunk_count` | Number of stored chunks |
| `started_at`, `completed_at` | Timing |
| `error` | Failure reason, when `state` is `failed` |

Only a snapshot in state `complete` can be restored.
Snapshot routes are tenant-scoped, so `GET /api/v1/opencomputers/snapshots/{id}` and `DELETE /api/v1/opencomputers/snapshots/{id}` take the snapshot ID alone, without a host.

## Restore a snapshot

```bash
miosa host backup snapshot fork <snapshot> --to-host <host> --to-path /restore
miosa host backup snapshot fork <snapshot> --overwrite
```

`--to-host` defaults to the host the snapshot came from, and `--overwrite` replaces files that already exist.

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/snapshots/$SNAPSHOT_ID/restore" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"target_host_id":"<host-id>","target_path":"/restore","overwrite":false}'
```

| Field | Type | Required | Description |
|---|---|---|---|
| `target_host_id` | string | Yes | Host to write onto |
| `target_path` | string | No | Directory to write into |
| `overwrite` | boolean | No | Replace existing files; default `false` |

A restore returns `202` with a `restore_id`.
It is asynchronous: watch the target host's filesystem or the [audit log](/docs/opencomputers/security/#audit-log) to confirm the files landed.

A restore writes real files onto a real host. Without `overwrite`, existing files are left alone, and the restore can still leave a partially restored directory if it fails midway.
Restore into a new path first, compare, and only then replace the live directory.

## What a backup does and does not cover

- It covers the files under one directory tree on one host. It does not image the operating system, and it does not capture running process state.
- It does not back up a database consistently on its own. Quiesce or dump the database into the backed-up directory before the schedule runs, or use the database's own backup tooling.
- It is not a substitute for a plan that covers losing the machine itself. Keep the credentials and configuration needed to rebuild the host somewhere other than the host.

# Billing and limits

URL: https://miosa.ai/docs/opencomputers/billing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/billing
Source: src/routes/docs/opencomputers/billing/+page.md
Description: What a plan allows on OpenComputers - hosts, containers, tunnels - and the operational caps on commands, transfers, backups, and tunnels.

# Billing and limits

Your machine is your own bill. You pay for the hardware, the power, the network, and the hosting, and MIOSA does not charge you for the machine.
MIOSA charges for platform usage at the rates on the [pricing page](/pricing); your plan sets limits, never the price.

This page covers the limits that a plan puts on OpenComputers, and the operational caps that apply to everyone.

## Plan limits

Plan limits are per organization.

| Plan | Hosts | Container and compose service slots | Tunnels per host |
|---|---|---|---|
| Developer | 3 | 2 | 0 |
| Business | 50 | 250 | 50 |
| Enterprise | 500 | 1000 | 500 |

Registering past a limit returns `402` with `error: "plan_limit_reached"`, plus the `limit` and `current` values.

A compose project counts its services against the same container budget, so a project with three services uses three slots.

Plan limits are enforced by the platform and can change between releases.
The authoritative value is the one in the `402` response, and the one the UI shows for your organization.

To raise a limit, contact support with your expected scale. See [Support](/docs/support/).

## Operational limits

These apply regardless of plan.

| Limit | Value |
|---|---|
| Command length in a job | 1 to 8192 characters |
| Arguments per job | 256 |
| Working directory length | 4096 characters |
| Job timeout | 1 to 3600 seconds; default 30 |
| Exec stream timeout | 30000 ms |
| File transfer chunk | 4 MiB per read or write |
| Backup chunk | 8 MiB compressed |
| Backup compression level | 1 to 22; default 19 |
| Backup retention | 1 to 365 snapshots, or 1 to 3650 days |
| Tunnel frame | 4 MiB |
| Tunnel connect timeout | 10 s |
| Tunnel response timeout | 30 s |
| Forwarded request headers per tunnel request | 64 |
| Container stats tick | 10 s |
| Mesh size | 253 hosts |
| Tags per host | 20 |
| Device browser token TTL | 3600 s |

Job commands are also recorded in audit truncated to 512 characters, and environment variable names are recorded without their values.

## Counters you can read

The platform meters usage per resource, and the counters are on the records you already fetch.

| Counter | Where |
|---|---|
| Host egress and ingress bytes | `usage.lifetime_bytes_egress` and `usage.lifetime_bytes_ingress` on the host record |
| Tunnel requests and bytes | `request_count`, `lifetime_bytes_ingress`, and `lifetime_bytes_egress` on the tunnel |
| Snapshot size | `total_bytes` and `compressed_bytes` on the snapshot |
| Container resource use | `last_cpu_percent`, `last_mem_mb`, and `last_stats_at` on the container |

For the platform-wide picture, use the [Pricing and limits](/docs/pricing/) page and the [Usage Rollup API](/docs/api-reference/usage-rollup/).

# Connect your first host

URL: https://miosa.ai/docs/opencomputers/connect
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/connect
Source: src/routes/docs/opencomputers/connect/+page.md
Description: Install the host agent, enroll a machine, verify a command on that exact host, and configure service startup for Linux, macOS, or Windows.

# Connect your first host

Enroll a machine you operate as an OpenComputer.
Your first success is a completed `hostname` command on that exact machine, followed by a verified service restart.
A saved key or an online badge alone is not the finish line.

## Before you start

- Outbound HTTPS and WebSocket access on port 443, including access to GitHub release downloads and `api.miosa.ai`.
- Shell access as the user that should run the agent, plus `curl` and a POSIX shell on Linux or macOS.
- A MIOSA account with access to OpenComputers, and either the `miosa` CLI or a platform API key authorized for the intended organization.
- `sudo` access and systemd if you follow the Linux background-service section.

Choose the agent's OS user deliberately: its permissions determine which local files and services the host can reach.
See the [security model](/docs/opencomputers/security/) before connecting sensitive workloads.

The prebuilt Linux agent target is x86-64.
On Linux ARM64, or on a platform with no prebuilt agent, follow the [OSA source installation instructions](https://github.com/Miosa-osa/OSA#install-in-one-command) rather than assuming the installer supports it.
An operating system appearing in registration does not guarantee desktop support for every architecture.

## 1. Install the agent on the machine

```bash
curl -fsSL https://raw.githubusercontent.com/Miosa-osa/OSA/main/scripts/install.sh -o /tmp/osa-install.sh
sh /tmp/osa-install.sh
osa version
```

If `osa` is not found, open a new shell and run `osa version` again.
Follow any platform-specific instructions printed by the installer.
For a pinned release, use the version-selection instructions in the [OSA installation guide](https://github.com/Miosa-osa/OSA#install-in-one-command).

Install the OSA agent from the release assets in the [OSA repository](https://github.com/Miosa-osa/OSA), then confirm the agent answers in a new terminal:

```powershell
osa version
```

Registration accepts `--platform windows`.
Desktop streaming depends on the agent build for your platform; a registered Windows or macOS host does not automatically have a working desktop.

## 2. Register the host and save its key

```bash
miosa host register studio --platform linux
```

`--platform` takes `macos`, `linux`, or `windows`.
`register` creates the host record and prints the host ID and the host key once.
Add `--quiet-key` to print only the key, and `--region` to pin a region.

Open OpenComputers in MIOSA, choose **Connect a computer**, and register the machine in the intended organization.
Give it a recognizable name, such as `lab-server`, and select the operating system.
Save the returned host ID and one-time host key.

The **host key** authenticates this machine's agent.
Your **platform API key** authorizes REST requests from your terminal or backend.
They are different credentials and are not interchangeable.

## 3. Point the agent at MIOSA

On the machine itself, configure the connection with the OSA agent:

```bash
osa opencomputers login
osa opencomputers enable --no-profile
```

Paste the host key when prompted by `login`.
The prompt accepts the credential as terminal input; use a private terminal session.
Configuration is written under the agent user's `~/.osa` directory, including `open_computers.toml` and the `open_computers.ed25519` identity file.
Preserve that identity when updating the agent.

`login` saves the key and `enable` enables host mode.
Neither command proves that a live session has started.

## 4. Start the host session

Start the headless agent in the machine's terminal:

```bash
OSA_OPEN_COMPUTERS_ENABLED=true osa serve
```

Keep it running while completing the first check from another terminal.
The agent initiates an authenticated outbound WebSocket connection to MIOSA.
No inbound management port or public IP is required.

Open the host in MIOSA, or list it from your terminal, and confirm a fresh heartbeat and the capability needed for command execution:

```bash
miosa host list --tag studio
miosa host get <host>
```

If the host does not connect, follow [Host stays offline](/docs/opencomputers/troubleshooting/#host-stays-offline).

## 5. Complete a command on the selected host

```bash
miosa host jobs <host>
miosa host job list <host>
miosa host fs ls <host> --path /tmp
```

`miosa host jobs <host>` lists recent jobs. `miosa host job get <host> <job>` shows one job and its output.

In a separate trusted terminal, set your platform API key and the returned host ID:

```bash
export MIOSA_API_KEY="<your-platform-api-key>"
export HOST_ID="<your-host-id>"
```

Confirm the host record:

```bash
curl --fail-with-body -sS "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

The response contains a `host` object.
Confirm its ID, name, heartbeat, and capabilities correspond to this machine.
Then run a read-only command:

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/exec" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"cmd":"hostname","stream":false,"timeout_ms":10000}'
```

Expected result, with your own job ID and hostname:

```json
{
  "job_id": "<job-id>",
  "exit_code": 0,
  "stdout": "lab-server\n",
  "stderr": ""
}
```

Compare `stdout` with `hostname` run directly on the machine.
With `stream: false` the API collects output; the default is `stream: true`, which returns SSE events until a terminal result.
For longer commands, use the [streaming exec contract](/docs/api-reference/open-computers/#run-a-job) instead of this short collected-output check.

Use the IDs from your own request and the same authorized organization context.
An accepted request is not proof that the command completed.
Keep the API key in your backend or terminal environment.

## 6. Run the agent as a service

After the command passes, stop the foreground `osa serve` process before starting a second instance.

The unit runs under the same user and home directory that hold the configured identity.
Run these commands as that user, not from a root login shell.
If this unit already exists, inspect it before replacing it; preserve any site-specific restrictions.

```bash
OSA_HOST_BIN="$(command -v osa)"
OSA_HOST_USER="$(id -un)"

sudo tee /etc/systemd/system/osa-opencomputers.service > /dev/null <<EOF_UNIT
[Unit]
Description=MIOSA OSA OpenComputers Host
After=network-online.target
Wants=network-online.target

[Service]
Type=simple
User=${OSA_HOST_USER}
Environment=HOME=${HOME}
Environment=OSA_OPEN_COMPUTERS_ENABLED=true
ExecStart=${OSA_HOST_BIN} serve
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target
EOF_UNIT

sudo systemctl daemon-reload
sudo systemctl enable --now osa-opencomputers.service
systemctl status osa-opencomputers.service --no-pager
```

Use your platform's service manager under the same agent user, and keep two things with the service:

- the `OSA_OPEN_COMPUTERS_ENABLED=true` environment variable, so the agent starts in host mode;
- the `~/.osa` directory, including `open_computers.toml` and the `open_computers.ed25519` identity file.

A launch agent on macOS and a Windows service both work this way.
Then confirm a fresh heartbeat in MIOSA.

Expect an active service, then verify a new heartbeat in MIOSA and repeat the `hostname` request.
An enabled service should start at boot, but verify that behavior after a scheduled reboot before relying on unattended work.

## 7. Disconnect or retire the host

For temporary maintenance, stop dispatching new work, inspect running jobs, and stop the agent:

```bash
miosa host jobs <host>
sudo systemctl stop osa-opencomputers.service
```

The unit remains enabled for the next boot.
For retirement, disable startup, log the agent out, and revoke the host:

```bash
sudo systemctl disable --now osa-opencomputers.service
osa opencomputers logout
miosa host rm <host> --yes
```

Revocation and logout do not erase the machine's files, and they do not prove that every child process has stopped.
Verify active work before removing access or retrying it elsewhere.

# Containers on a host

URL: https://miosa.ai/docs/opencomputers/containers
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/containers
Source: src/routes/docs/opencomputers/containers/+page.md
Description: Run Docker or Podman containers on one of your hosts, stream their logs and resource usage, and keep docker-compose projects running.

# Containers on a host

A host runs its own container runtime, and MIOSA manages containers on it: create, start, stop, restart, delete, and stream logs and resource usage.
Everything is addressed by the host ID and the container ID, and every operation is tenant-scoped.

MIOSA does not build the image for you. Your image must already be pullable by the host's runtime.

## Run a container

```bash
miosa host container run <host> --image nginx:alpine --name web --set PORT=8080
miosa host container list <host>
miosa host container get <host> <container>
```

`miosa host container run` takes `--image`, `--name`, `--cmd` (repeatable), `--set KEY=VALUE` (repeatable), and `--restart`.
Aliases: `miosa host containers`, `miosa host container create`.

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/containers" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"web","image":"nginx:alpine","env":{"PORT":"8080"},"ports":[{"host_port":8080,"container_port":8080}]}'
```

| Field | Type | Required | Description |
|---|---|---|---|
| `name` | string | Yes | 1 to 63 characters, starting with a letter or digit |
| `image` | string | Yes | Image reference the host's runtime can pull |
| `command` | string[] | No | Command and arguments; default `[]` (the image default) |
| `env` | object | No | Environment variables as a map; default `{}` |
| `ports` | object[] | No | `{host_port, container_port, protocol}`; `protocol` defaults to `tcp` |
| `volumes` | object[] | No | `{source, target, readonly}`; `readonly` defaults to `false` |
| `restart_policy` | string | No | `no`, `on-failure`, `always`, or `unless-stopped` (default) |
| `runtime` | string | No | `auto` (default), `docker`, or `podman` |

The response is `{"container": {...}}` with `id`, `name`, `image`, `command`, `env`, `ports`, `volumes`, `restart_policy`, `runtime`, `state`, `runtime_id`, `runtime_name`, `exit_code`, `started_at`, `stopped_at`, `last_error`, `last_cpu_percent`, `last_mem_mb`, and `last_stats_at`.

Container states are `provisioning`, `running`, `stopped`, `failed`, `removing`, and `removed`.

`create` returns as soon as the host accepts the request. Read `state` before you rely on the container: `provisioning` is not `running`, and `last_error` is where a failed start explains itself.

## Logs

```bash
miosa host container logs <host> <container>
miosa host container logs <host> <container> --json
```

Streams until the connection ends or you press Ctrl-C. With `--json`, each event is one JSON object per line.

```bash
curl -N --fail-with-body -sS \
  "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/containers/$CONTAINER_ID/logs" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

An SSE stream of `{stream, line, ts}` frames, where `stream` is the source stream on the container.

## Stats

```bash
miosa host container stats <host> <container>
miosa host container stats <host> <container> --json
```

```bash
curl -N --fail-with-body -sS \
  "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/containers/$CONTAINER_ID/stats" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

An SSE stream that ticks about every 10 seconds with `{container_id, cpu_percent, mem_mb, stats_at}`, and sends a final `{state, container_id}` frame when the container stops.

The latest sample is also kept on the container record as `last_cpu_percent`, `last_mem_mb`, and `last_stats_at`.

## Lifecycle

```bash
miosa host container start <host> <container>
miosa host container stop <host> <container>
miosa host container restart <host> <container>
miosa host container rm <host> <container> --force --yes
```

| Action | REST | Notes |
|---|---|---|
| Start | `POST /opencomputers/hosts/{host_id}/containers/{id}/start` | Only from `stopped` or `failed`; returns `409` otherwise |
| Stop | `POST .../containers/{id}/stop` | Only from `running`; accepts a `timeout_s` grace period, default 10 |
| Restart | `POST .../containers/{id}/restart` | Allowed from `running`, `stopped`, or `failed` |
| Update | `PATCH .../containers/{id}` | `image`, `command`, `env`, `ports`, `volumes`, `restart_policy`, `runtime` |
| Delete | `DELETE .../containers/{id}?force=true` | `force` deletes a running container; returns `202` |

Deleting a container does not delete its volumes for you unless you asked for the volume to be removed with the container.

## Compose projects

A compose project is a docker-compose file the host keeps running.

```bash
miosa host compose list <host>
miosa host compose up <host> app --build --pull
miosa host compose down <host> app --remove-volumes
miosa host compose rm <host> app --yes
```

| Action | REST |
|---|---|
| List | `GET /opencomputers/hosts/{host_id}/compose-projects` |
| Create | `POST .../compose-projects` with `name`, `yaml` (required), `env`, `pull`, `build` |
| Up | `POST .../compose-projects/{id}/up` |
| Down | `POST .../compose-projects/{id}/down` with `remove_volumes` |
| Delete | `DELETE .../compose-projects/{id}` |
| Events | `GET .../compose-projects/{id}/events` (SSE) |

Compose project states are `creating`, `running`, `partial`, `stopped`, `failed`, and `removing`.
The events stream carries `{type, payload}` frames where `type` is `progress`, `log`, or `error`.

`--remove-volumes` destroys the project's volumes. Confirm what you intend to lose before using it on a stateful project.

## Plan limits

The number of container slots a tenant can use depends on the plan, and a compose project counts its services against the same budget.

| Plan | Containers and compose service slots |
|---|---|
| `free` | 2 |
| `starter` | 10 |
| `pro` | 50 |
| `team` | 250 |
| `enterprise` | 1000 |

Exceeding the limit returns `402` with `error: "plan_limit_reached"`, plus the `limit` and `current` values.
See [Billing and limits](/docs/opencomputers/billing/) for the other plan-scoped limits.

Containers share the host's kernel. They are not Firecracker microVMs, and they do not give you the isolation or the disposable lifecycle of a [sandbox](/docs/develop/sandboxes/).
Use containers when you want a long-lived service on a machine you own.

# Devices

URL: https://miosa.ai/docs/opencomputers/devices
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/devices
Source: src/routes/docs/opencomputers/devices/+page.md
Description: The device model - one id-addressed surface for running commands, moving files, exposing ports, and driving lifecycle across runtime kinds.

# Devices

A device is any runtime MIOSA can run a command on.
`<device>` is an id, not a name, and the device surface does not care which kind of runtime answers.

Use it when a script has to work across runtime kinds, or when you have an id and do not know what it is.

The `/api/v1/devices` endpoints resolve sandbox workers and managed Computers - the runtimes MIOSA provisions for you.
A machine you connect with OpenComputers is a **host** and is addressed by its host ID through the [OpenComputers endpoints](/docs/api-reference/open-computers/) instead.
The [`miosa device`](/docs/cli/devices/) command is the CLI's unified view; for a host, use the typed [`miosa host`](/docs/cli/platform/#your-own-hosts) family.

## List and inspect

```bash
miosa device list
miosa device list --status running --name web --limit 20
miosa device get <device>
miosa device capabilities <device>
```

Aliases: `miosa devices`, `show` for `get`, `caps` for `capabilities`.

```bash
curl --fail-with-body -sS "https://api.miosa.ai/api/v1/devices?status=running" \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl --fail-with-body -sS "https://api.miosa.ai/api/v1/devices/$DEVICE_ID/capabilities" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

`GET /api/v1/devices` accepts `status`, `name`, and `limit` (default 50).

A device record carries `id`, `name`, `slug`, `template`, `kind`, `state`, `ip_address`, `node_id`, `running`, `terminal`, and its `capabilities`.

## Check capabilities before you act

Capabilities are the difference between a script that works everywhere and one that fails on half your devices.

| Capability | Sandbox worker | Computer |
|---|---|---|
| `exec` | yes | yes |
| `files` | yes | yes |
| `browser` | no | yes |
| `artifacts` | yes | no |
| `live_server` | yes | yes |
| `connectors` | yes | yes |
| `pause`, `resume` | yes | yes |
| `snapshots` | yes | no |

Read the capability rather than assuming it from the device's name.

## Run a command

```bash
miosa device exec <device> -- uname -a
miosa device exec <device> -c "npm test" --timeout-ms 120000
```

`miosa device exec` exits with the remote command's status, like `miosa exec`.

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/devices/$DEVICE_ID/exec" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"command":"uname -a","timeout_ms":30000}'
```

The body takes `command` (required) and `timeout_ms` or `timeout` in seconds (default 30).

Exec on a device resolves a **running** target.
A device that is not running returns `DEVICE_NOT_RUNNING` with the current `state` rather than starting it for you.

## Files

```bash
miosa device files <device> --path /workspace
miosa device read <device> --path /workspace/out.json
miosa device write <device> --path /workspace/app.py --content "print(1)"
```

Aliases: `ls` for `files`.

```bash
curl --fail-with-body -sS "https://api.miosa.ai/api/v1/devices/$DEVICE_ID/files?path=/workspace" \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl --fail-with-body -sS "https://api.miosa.ai/api/v1/devices/$DEVICE_ID/files/read?path=/workspace/out.json" \
  -H "Authorization: Bearer $MIOSA_API_KEY"

curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/devices/$DEVICE_ID/files/write" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"path":"/workspace/app.py","content":"print(1)"}'
```

`files` lists a directory and defaults to `/workspace`. `files/read` takes a required `path` and returns the content base64-encoded with `encoding: "base64"`. `files/write` takes `path` plus either `content_base64` or `content`.

`miosa device read` returns the file contents base64-encoded, and `miosa device write` takes the contents from `--content` or a JSON body with `--file`.

## Expose a port

```bash
miosa device expose <device> 3000

curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/devices/$DEVICE_ID/expose" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"port":3000}'
```

On a host, the typed [tunnel commands](/docs/opencomputers/tunnels/) give you the fuller surface: access mode, slug control, and list and delete.

## Browser URL

```bash
miosa device browser <device>
```

`GET /api/v1/devices/{id}/browser` returns the streamed desktop for a computer, with `desktop_url`, `ws_url`, `token`, `expires_at`, `computer_id`, and `slug`, and a one-hour token TTL.
A sandbox returns `BROWSER_UNSUPPORTED_FOR_SANDBOX`; use a [Computer](/docs/computer-use/) when you need a desktop.

## Lifecycle

```bash
miosa device extend <device> --timeout 2h
miosa device pause <device>
miosa device resume <device>
miosa device stop <device>
miosa device rm <device> --yes
```

| Action | REST | Notes |
|---|---|---|
| Extend | `POST /devices/{id}/extend` with `timeout_sec` | Replaces the time to live |
| Pause | `POST /devices/{id}/pause` | Keeps the disk |
| Resume | `POST /devices/{id}/resume` | |
| Stop | `POST /devices/{id}/stop` | Keeps the disk |
| Destroy | `DELETE /devices/{id}` | Permanent; returns state `destroyed` |

Each lifecycle call returns the device's new `state`.

## Error codes

| Code | Status | Meaning |
|---|---|---|
| `MISSING_PARAM` | 400 | A required field is absent; the response names it |
| `INVALID_PARAM` | 400 | A field is present but not usable |
| `INVALID_BASE64` | 400 | File content was not valid base64 |
| `NOT_FOUND` | 404 | The device does not exist, or is not yours |
| `DEVICE_NOT_RUNNING` | 409 | The device is not running; the response carries its `state` |
| `UNSUPPORTED_FOR_COMPUTER` | 422 | The operation does not apply to a computer |
| `BROWSER_UNSUPPORTED_FOR_SANDBOX` | 422 | Browsing requires a computer |
| `DEVICE_OPERATION_FAILED` | 422 | The runtime rejected the operation |

# GitHub Actions runners

URL: https://miosa.ai/docs/opencomputers/gha-runners
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/gha-runners
Source: src/routes/docs/opencomputers/gha-runners/+page.md
Description: Register self-hosted GitHub Actions runners on your own hosts for one repository, and stream their activity from MIOSA.

# GitHub Actions runners

A runner is a GitHub Actions runner the host keeps registered for one repository.
MIOSA installs and supervises the runner process on your machine, so a workflow job runs on hardware you control.

Use this when a build needs a GPU, a large local cache, software that only exists on your machine, or a network path that GitHub-hosted runners cannot reach.

## Register a runner

```bash
miosa host gha-runner list <host>
miosa host gha-runner new <host> --repo https://github.com/acme/app --token <token>
miosa host gha-runner new <host> --repo https://github.com/acme/app --token-secret GH_TOKEN --ephemeral
miosa host gha-runner get <host> <runner>
```

Aliases: `miosa host gha-runners`, `miosa host runner`, `miosa host runners`, and `create` or `add` for `new`.

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/gha-runners" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"repo_url":"https://github.com/acme/app","name":"gpu-builder","labels":["gpu","linux"],"pat_secret_id":"<secret-id>"}'
```

| Field | Type | Required | Description |
|---|---|---|---|
| `repo_url` | string | Yes | Repository URL; must be on `github.com` or a `*.github.com` host |
| `name` | string | Yes | Runner name, 1 to 128 characters; unique per host |
| `labels` | string[] | No | Runner labels; default `[]` |
| `ephemeral` | boolean | No | Deregister the runner after one job; default `false` |
| `pat_secret_id` | string | One of | ID of an existing host secret holding a GitHub token |
| `pat_value` | string | One of | Inline token; MIOSA stores it as a host secret for you |

The CLI flag names differ from the API field names: `--repo` maps to `repo_url`, `--token` to `pat_value` (sent to the host and not stored), and `--token-secret` to `pat_secret_id`.
`--label` is repeatable, and `--name` defaults to a generated name.

The GitHub token is not stored in a readable form and is never returned by any read.
Prefer `pat_secret_id` or `--token-secret` so the value lives in a [host secret](/docs/opencomputers/hosts/#secrets) rather than in a command you might paste elsewhere.

`repo_url` must point at `github.com`. A GHES URL is rejected with a `422`.

## Runner states

| State | Meaning |
|---|---|
| `provisioning` | MIOSA is installing and starting the runner |
| `idle` | Registered and waiting for a job |
| `running_job` | Executing a workflow job |
| `offline` | Registered but not reachable |
| `failed` | Installation or registration failed |
| `removed` | Deregistered |

`current_job` is set while the runner is executing, and `last_activity_at` tells you when it last did anything.

## Watch a runner

```bash
miosa host gha-runner events <host> <runner>
miosa host gha-runner events <host> <runner> --json
```

Streams events as the runner picks up and finishes jobs. Ctrl-C stops the stream.

```bash
curl -N --fail-with-body -sS \
  "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/gha-runners/$RUNNER_ID/events" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Named SSE events: `progress`, `ready`, `status`, `error`, and `removed`.

## Repair and remove

```bash
miosa host gha-runner refresh <host> <runner>
miosa host gha-runner rm <host> <runner> --yes
```

| Action | REST | Notes |
|---|---|---|
| Refresh | `POST .../gha-runners/{runner_id}/refresh` | Reinstalls and restarts the runner; returns `{"ok": true}` |
| Remove | `DELETE .../gha-runners/{runner_id}` | Stops the runner and deregisters it from GitHub; returns `204` |

`refresh` is the fix for a runner stuck in `failed` or `offline` after an upgrade, rather than deleting and re-registering.
Both actions can return `429` if the GitHub API rate-limits the registration calls.

## Reference it in a workflow

Point a workflow job at the runner's labels:

```yaml
jobs:
  build:
    runs-on: [self-hosted, gpu, linux]
```

A job runs on your machine only while the host agent is connected and the runner is `idle`.
If the host goes offline mid-job, the workflow fails on GitHub's side; check `miosa host gha-runner get` and the [runner events](#watch-a-runner) before retrying.

# Hosts and capabilities

URL: https://miosa.ai/docs/opencomputers/hosts
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/hosts
Source: src/routes/docs/opencomputers/hosts/+page.md
Description: Inspect enrolled hosts, read their runtime and services, run commands on one host or a group, manage files, apps, compose projects, secrets, SSH keys, and clusters.

# Hosts and capabilities

A host is one enrolled machine.
Every host is addressed by its host ID, and every host command takes `<host>` as its first argument.
The host ID is stable; the machine's IP address and hostname are not the identity MIOSA uses.

```bash
miosa host list --tag studio
miosa host get <host>
```

`miosa host list` takes `--tag` to narrow to hosts carrying a tag.
`miosa host get <host>` returns the host record with its platform, region, tags, and reported capabilities.
Aliases: `miosa hosts`, `miosa host`.

## What a host reports

| Command | What it tells you |
|---|---|
| `miosa host get <host>` | The host record: state, platform, region, tags, capabilities |
| `miosa host metrics <host>` | CPU, memory, and disk of the host |
| `miosa host runtime <host>` | The container runtime the host is running |
| `miosa host services <host>` | The services running on the host |
| `miosa host jobs <host>` | Recent commands dispatched to the host |

Registration alone proves neither readiness nor feature parity.
Treat a fresh heartbeat plus a completed operation as the evidence that a host is usable for the capability you need.

A common MIOSA interface does not mean every host supports every managed operation.
Direct execution runs within the host user's operating-system permissions; it does not automatically place each command in an isolated microVM.
Registration does not turn an arbitrary host into a sandbox worker pool or an Docker Host host.

## Run a command

Commands dispatched to a host are jobs.

```bash
miosa host job list <host>
miosa host job get <host> <job>
miosa host job cancel <host> <job>
```

`miosa host job` has aliases `jobs` and `exec`, so `miosa host exec <host> -- uname -a` is the same surface.
Cancelling a job is not proof that the remote process stopped; confirm the outcome before retrying work with side effects.

The REST equivalent is the [exec endpoint](/docs/api-reference/open-computers/#run-a-job), which streams SSE by default and returns collected output when you send `"stream": false`.

### Run on every host in a group

A group is a named set of hosts. Running a command or installing an app on a group runs it on every member.

```bash
miosa host group new ci --description "CI workers"
miosa host group add ci <host>
miosa host group exec ci --cmd npm --arg test --cwd /srv/app --timeout-ms 120000
miosa host group get ci
miosa host group remove ci <host>
miosa host group rm ci --yes
```

Deleting a group leaves its hosts in place.

## Files on a host

Paths are on the host's own file system, not a sandbox workspace.

```bash
miosa host fs ls <host> --path /srv/app
miosa host fs stat <host> --path /srv/app/package.json
miosa host fs mkdir <host> --path /srv/app/logs
miosa host fs rm <host> --path /srv/app/old.log --yes
```

`miosa host fs ls` defaults to the agent user's home directory.
The same operations are available over REST under `/opencomputers/hosts/{id}/fs/*` - see the [OpenComputers API](/docs/api-reference/open-computers/#file-system).

## Tags

Tags group hosts for selection and batch work.

```bash
miosa host tag add <host> gpu
miosa host tag list
miosa host tag rm <host> gpu
```

`miosa host list --tag gpu` then selects hosts without you tracking IDs by hand.

## Secrets

Host secrets are encrypted key-value pairs that the host agent can use at runtime.
Values are never returned by a list call.

```bash
miosa host secret list <host>
miosa host secret set <host> GITHUB_TOKEN --description "CI token"
miosa host secret set <host> DEPLOY_KEY --key-stdin < deploy.key
miosa host secret rm <host> GITHUB_TOKEN --yes
```

`secret set` prompts for the value or reads it from standard input with `--key-stdin`, so the value does not land in your shell history.

## SSH keys

Only public keys are handled.

```bash
miosa host ssh-key add <host> --name roberto --public-key "ssh-ed25519 AAAA..."
miosa host ssh-key import <host> <github-user>
miosa host ssh-key list <host>
miosa host ssh-key rm <host> <key> --yes
```

`ssh-key import` copies the public keys a GitHub user has published.

## Apps

The catalog lists what MIOSA can install; install puts one on a host.

```bash
miosa host app catalog
miosa host app install <host> redis
miosa host app list <host>
miosa host app health <host> redis
miosa host app start <host> redis
miosa host app uninstall <host> redis --yes
```

Check `miosa host app health` after an install rather than assuming the app came up.

## Compose projects

A compose project is a docker-compose file the host keeps running.

```bash
miosa host compose list <host>
miosa host compose up <host> app --build --pull
miosa host compose down <host> app --remove-volumes
miosa host compose rm <host> app --yes
```

`--build` builds images first and `--pull` pulls them first.
`--remove-volumes` deletes the project's volumes, so confirm what you intend to lose before using it on a stateful project.

## Containers

Containers on a host are covered in [Containers](/docs/opencomputers/containers/).

## Clusters

A cluster is a group of your hosts that serve one model together, exposed as an OpenAI-compatible endpoint.

```bash
miosa host cluster list
miosa host cluster get <cluster>
miosa host cluster start <cluster>
miosa host cluster stop <cluster>
miosa host cluster rm <cluster> --yes
```

Clusters are created over the API with `host_ids`, `name`, and `model`; see [Inference clusters](/docs/api-reference/open-computers/#inference-clusters).

## Remove a host

```bash
miosa host rm <host> --yes
```

Removing a host ends its ability to authenticate.
It does not erase the machine's files and does not prove that its processes stopped.

# Meshes

URL: https://miosa.ai/docs/opencomputers/meshes
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/meshes
Source: src/routes/docs/opencomputers/meshes/+page.md
Description: Link several of your hosts on a private encrypted WireGuard network so they reach each other without going over the public internet.

# Meshes

A mesh is a named private network across several of your hosts.
MIOSA assigns each member an address in the mesh's `/24` and distributes WireGuard keys, so members reach each other directly without exposing anything on the public internet.

Use a mesh when services on one host need to talk to services on another: a database on one box, an application on a second, a GPU worker on a third.

## Create a mesh

```bash
miosa host mesh list
miosa host mesh new lab --host <host> --host <host>
miosa host mesh get lab
```

Aliases: `miosa host meshes`.

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/meshes" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"lab","host_ids":["<host-1>","<host-2>"]}'
```

| Field | Type | Required | Description |
|---|---|---|---|
| `name` | string | Yes | 1 to 80 lowercase alphanumeric or hyphen characters |
| `host_ids` | string[] | No | Hosts to add at creation; default `[]` |

A mesh carries a `cidr` in the form `10.x.x.0/24`, a `state`, and a `listen_port_base` that defaults to `51820`.
Mesh states are `provisioning`, `active`, `failed`, and `torn_down`.

## Manage membership

```bash
miosa host mesh add-host lab <host>
miosa host mesh remove-host lab <host> --yes
miosa host mesh rm lab --yes
```

| Action | REST |
|---|---|
| Add a host | `POST /opencomputers/meshes/{id}/hosts/{host_id}` |
| Remove a host | `DELETE /opencomputers/meshes/{id}/hosts/{host_id}` |
| Delete the mesh | `DELETE /opencomputers/meshes/{id}` |

Adding a host returns the new peer.
Removing a host leaves the host itself in place; deleting the mesh tears down the WireGuard configuration before the record is removed.

The mesh's `/24` address space allows 253 members. Adding one past that returns `422` with `mesh /24 is full (max 253 hosts)`.
If you outgrow a single mesh, contact support rather than nesting meshes yourself.

## Inspect peers

`miosa host mesh get <mesh>` and `GET /opencomputers/meshes/{id}` return the mesh with its current peer list.

| Peer field | Meaning |
|---|---|
| `id` | Peer record ID |
| `host_id` | The host this peer represents |
| `assigned_ip` | Address in the mesh's `10.x.x.x` range |
| `pubkey` | The peer's WireGuard public key |
| `endpoint` | Last seen endpoint |
| `latest_handshake` | When the tunnel last completed a handshake |
| `rx_bytes`, `tx_bytes` | Traffic counters |
| `state` | `pending_key`, `configured`, `active`, or `failed` |

Peer states are the fastest way to answer "is this host actually reachable over the mesh": an `active` peer with a recent `latest_handshake` is, and a `pending_key` peer never joined.

## Events

```bash
miosa host mesh events lab
```

Streams host joins, key rotation, and state changes until you press Ctrl-C.

```bash
curl -N --fail-with-body -sS \
  "https://api.miosa.ai/api/v1/opencomputers/meshes/$MESH_ID/events" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Named SSE events: `mesh_peer_active`, `mesh_peer_down`, and `mesh_status`.

## Security notes

- Mesh traffic is encrypted and stays inside the mesh. It does not become reachable from the internet because a host is a member.
- MIOSA distributes the WireGuard keys. An operator with control-plane access can add a host to a mesh, so treat mesh membership as a privileged change and review it in the [audit log](/docs/opencomputers/security/#audit-log).
- A mesh does not grant a host access to anything else on another host beyond the ports that host's firewall and services allow.

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/reference
Source: src/routes/docs/opencomputers/reference/+page.md
Description: Every OpenComputers endpoint group, the CLI command families that call them, and the SDK namespaces that wrap them.

# API, CLI, and SDK reference

Everything OpenComputers is reachable three ways: the REST API, the `miosa` CLI, and the SDKs.
This page is the map. Field-level detail for hosts, jobs, files, tunnels, agents, and clusters lives in the [OpenComputers API reference](/docs/api-reference/open-computers/).

## REST API

Base path: `/api/v1/opencomputers`. All calls need `Authorization: Bearer <platform-api-key>`.

| Clusters | `GET, POST /clusters`, `GET, DELETE /clusters/:id`, `POST /clusters/:id/start`, `POST /clusters/:id/stop` |

### Streaming endpoints

These answer with Server-Sent Events and keep the connection open:

| Stream | Endpoint |
|---|---|
| Job output | `GET /hosts/:id/exec/:job_id/stream` |
| Host lifecycle | `GET /hosts/events` |
| Container logs | `GET /hosts/:host_id/containers/:id/logs` |
| Container stats | `GET /hosts/:host_id/containers/:id/stats` |
| Compose events | `GET /hosts/:host_id/compose-projects/:id/events` |
| Mesh events | `GET /meshes/:id/events` |
| Runner events | `GET /hosts/:id/gha-runners/:runner_id/events` |
| Agent session events | `GET /hosts/:id/agent/sessions/:session_id/events` |
| App install events | `GET /hosts/:id/apps/installs/:install_id/events` |
| Cluster events | `GET /clusters/:id/events` |
| Workspace events | `GET /hosts/:host_id/workspaces/:wid/events` |
| Audit feed | `GET /audit/live` |

`GET /hosts/events` uses a ticket rather than a bearer token: mint one with `POST /api/v1/opencomputers/hosts/events/sse-ticket`, then connect with `?ticket=`.

### Inference

An active cluster serves an OpenAI-compatible endpoint:

| Endpoint | Purpose |
|---|---|
| `POST /inference/:slug/v1/chat/completions` | Chat completions |
| `POST /inference/:slug/v1/completions` | Text completions |
| `GET /inference/:slug/v1/models` | Model list |

### Unauthenticated endpoints

| Endpoint | Purpose |
|---|---|
| `POST /opencomputers/hosts/registration-status` | Check whether a host key is valid and connected |
| `POST /opencomputers/schedules/trigger/:token` | Trigger a schedule from a webhook, using its one-time token |
| `GET /opencomputers/osa/latest` | The latest agent release manifest |
| `ANY /t/:slug/*path` | The public tunnel proxy; the tunnel's own access mode decides who gets through |

## CLI

The CLI exposes OpenComputers as `miosa host`, with `miosa host` as an alias.

```bash
miosa host register <name> --platform linux|macos|windows
miosa host list --tag <tag>
miosa host get <host>
miosa host metrics <host>
miosa host runtime <host>
miosa host services <host>
miosa host jobs <host>
miosa host job list|get|cancel <host> [job]
miosa host fs ls|stat|mkdir|rm <host> --path <path>
miosa host tag list|add|rm
miosa host group list|get|new|add|remove|exec|rm
miosa host secret list|set|rm
miosa host ssh-key list|add|import|rm
miosa host app catalog|list|install|start|health|uninstall
miosa host agent runs|run|cancel
miosa host rm <host> --yes
```

```bash
miosa host container list|get|run|start|stop|restart|rm
miosa host container logs|stats <host> <container>
miosa host compose list|up|down|rm
miosa host mesh list|new|get|add-host|remove-host|events|rm
miosa host tunnel list|get|new|rm
miosa host gha-runner list|new|get|events|refresh|rm
miosa host backup list|new|update|trigger|pause|resume|rm
miosa host backup snapshot list|get|fork|rm
miosa host cluster list|get|start|stop|rm
```

```bash
miosa device list
miosa device get|capabilities <device>
miosa device exec <device> -- <command>
miosa device files|read|write <device> --path <path>
miosa device expose <device> <port>
miosa device browser <device>
miosa device extend|pause|resume|stop|rm <device>
```

`miosa host` and `miosa device` both accept the global flags (`--json`, `--org`, `--profile`, `--timeout`, and others). See the [CLI reference](/docs/cli/platform/#your-own-hosts) for the full command and flag list.

## SDKs

| SDK | Namespace |
|---|---|
| [TypeScript](/docs/sdks/typescript/) | `client.openComputers` |
| [Python](/docs/sdks/python/) | `client.open_computers` |
| [Go](/docs/sdks/go/) | `client.OpenComputers` |
| [Elixir](/docs/sdks/elixir/) | `Miosa.OpenComputers.*` modules |

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY });

const host = await miosa.openComputers.hosts.create({ name: 'studio', platform: 'linux' });
console.log(host.host_key);                       // shown once

const job = await miosa.openComputers.jobs.start(host.id, { command: 'uname -a' });
console.log(job.links.stream);                   // stream this job
```

```python

client = miosa.Miosa(api_key="msk_...")

for host in client.open_computers.hosts.list().data:
    print(host.id, host.status)
```

Coverage differs by language. The Python and Elixir SDKs wrap the widest surface - containers, compose, meshes, backups, runner provisioning, schedules, shares, alerts, audit, and webhooks. The TypeScript and Go SDKs cover hosts, jobs, files, tunnels, agents, clusters, and secrets.
When your language does not wrap a resource, call the REST endpoint directly.

Host rename is not available on the tenant API, so SDK `update` methods for hosts raise an unsupported error rather than sending a request. Rename is possible only on the admin surface. Use tags to group hosts instead.

# Security model

URL: https://miosa.ai/docs/opencomputers/security
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/security
Source: src/routes/docs/opencomputers/security/+page.md
Description: How the host agent connects, what MIOSA can and cannot reach on your machine, which credentials exist, and how audit and revocation work.

# Security model

OpenComputers inverts the usual direction of a management connection.
The agent on your machine dials out to MIOSA; MIOSA never dials in.
That single design decision determines most of what is and is not possible here.

Diagram:
flowchart LR
  subgraph Prem["Your machine"]
    Agent["MIOSA host agent"]
    User["Agent OS user"]
    Local["Files and services<br/>reachable by that user"]
    Agent --> User
    User --> Local
  end
  Agent -->|"Outbound authenticated WebSocket :443"| CP["MIOSA control plane"]
  CP -->|"Authorized operation"| Agent
  CP -->|"Nothing inbound"| X["No inbound port,<br/>no public IP required"]

## What MIOSA can do

- Send an authorized operation over the session the agent already opened: a command, a file read or write, a container action, a backup, or a tunnel dial.
- Read the host's reported state: platform, architecture, capabilities, runtime, tags, heartbeat, agent version, and job history.
- Route an inbound HTTP request down an existing session, but only through a [tunnel you created](/docs/opencomputers/tunnels/) and only if the request satisfies that tunnel's access mode.

## What MIOSA cannot do

- Open a connection to your machine spontaneously. There is no inbound management port and no requirement for a public IP.
- Act with more privilege than the agent's own operating-system user. Direct execution runs as that user, with that user's filesystem permissions and network reach.
- See files the agent user cannot read, or services that user cannot reach.
- Replace your operating-system controls. The agent is not a sandbox, a hypervisor, or a jail.

Running a command on a host executes it in the host's own environment, not in an isolated microVM.
Registration alone does not make a host a sandbox worker pool or an Docker Host host.
If you need isolation, put the work in a [sandbox](/docs/develop/sandboxes/) instead of on a host.

## Credentials

Two credentials exist, they have different jobs, and they are not interchangeable.

| Credential | Who uses it | Lifetime |
|---|---|---|
| **Host key** | The agent on the machine, from `osa opencomputers login` | Returned once at registration; revocable |
| **Platform API key** | Your terminal, backend, or SDK | Managed in [API keys](/docs/platform/api-keys/) |

The host also keeps an Ed25519 identity file, `~/.osa/open_computers.ed25519`, which pins the machine's identity.
Preserve that file across agent upgrades.
If it is lost, revoke the host and register a new one rather than copying another machine's identity or disabling verification.

You can check whether a host key is still valid without touching the host:

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/hosts/registration-status" \
  -H "Content-Type: application/json" \
  -d '{"host_key":"<host-key>"}'
```

It answers `{connected, state, host}`, with `410` for a revoked key and `401` for an invalid one.

## Authorization

Operations are authorized at the control plane, and every record is tenant-scoped.

- Commands dispatched to a host require the `opencomputers:write` scope.
- Host runtime registration, enrollment, and certification use `cloud:read` and `cloud:write`.
- Host listing, files, containers, tunnels, meshes, backups, and secrets rely on the API pipeline's organization authorization and workspace membership, and each handler resolves the resource through a tenant-scoped lookup.

A host ID from another organization resolves to nothing, not to someone else's machine.

## Secrets

Host and tenant secrets are encrypted key-value pairs.
List calls return names, descriptions, and IDs, never values.

```bash
miosa host secret set <host> GITHUB_TOKEN --key-stdin < token.txt
miosa host secret list <host>
```

The REST reveal endpoint, `POST /api/v1/opencomputers/hosts/{id}/secrets/{secret_id}/reveal`, is the only way to read a value back, and every call is audit-logged.

## Audit log

Every authorization-relevant action lands in the OpenComputers audit log.

```bash
curl --fail-with-body -sS "https://api.miosa.ai/api/v1/opencomputers/audit?limit=50" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

| Endpoint | What it does |
|---|---|
| `GET /opencomputers/audit` | Cursor-paginated events; filter by `kind`, `host_id`, `actor`, `from`, and `to` |
| `GET /opencomputers/audit/export` | The same data as JSON or CSV, up to 5000 rows |
| `GET /opencomputers/audit/verify` | Verifies the integrity chain and reports the last good index |
| `GET /opencomputers/audit/:id` | One event |
| `GET /opencomputers/audit/live` | A live SSE feed |

Run `verify` on a schedule: it answers whether the stored audit history is intact, which is what makes the log useful after an incident.

## Webhooks

OpenComputers webhooks POST events to your endpoint with an HMAC-SHA256 signature over the raw body, under a signing secret returned once when the webhook is created.

```bash
curl --fail-with-body -sS -X POST "https://api.miosa.ai/api/v1/opencomputers/webhooks" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"host-alerts","url":"https://example.com/hooks/miosa","events":["host.disconnected"]}'
```

Verify the signature over the exact bytes you received, before you parse them.
`GET .../webhooks/{id}/deliveries` shows recent attempts, and `POST .../webhooks/{id}/test` sends one on demand.
See [Webhooks](/docs/integrations/webhooks/) for the general delivery contract.

## Data boundaries

Executing on your machine keeps the execution on your machine.
It does not mean every byte stays there.

| Data | Where it travels |
|---|---|
| The command and its arguments | Sent over the session; the command is recorded in audit |
| Command output and file contents you request | Returned through MIOSA as part of the workflow |
| Backup chunks | Uploaded to MIOSA storage, encrypted at rest |
| Desktop and terminal streams | Routed through MIOSA while a session is open |
| Model requests from an agent run | Sent to the model endpoint you configured, which may be a third party |

Set the agent's permissions, the tunnel access modes, and the model endpoints to match the data you are willing to move.
For a fuller treatment of hardware ownership and connectivity, see [Shared responsibility](/docs/infrastructure/shared-responsibility/).

## Revocation and teardown

```bash
miosa host rm <host> --yes
```

Revoking a host ends its ability to authenticate immediately.
It does not erase the machine's files, and it does not stop a process already running there.
Before you revoke or retire a host, stop new work, inspect its [jobs](/docs/opencomputers/hosts/#run-a-command), and confirm the outcome of anything in flight.

# OpenComputers troubleshooting

URL: https://miosa.ai/docs/opencomputers/troubleshooting
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/troubleshooting
Source: src/routes/docs/opencomputers/troubleshooting/+page.md
Description: Diagnose offline hosts, rejected credentials, failed commands, container, mesh, runner, backup, and tunnel problems.

# OpenComputers troubleshooting

Start with the exact host ID, organization, and operation that failed.
Check both the control-plane record and the machine itself.
A working login, a healthy API endpoint, or a saved host key is not proof that the host can execute your request.

The fastest first check is always the same:

```bash
miosa host get <host>
miosa host jobs <host>
```

`state` and `connected` describe now; the job list describes what actually happened.

## Host stays offline

1. Confirm the machine is awake and its network connection works.
2. Check the agent process on the host; for the systemd setup in [Connect your first host](/docs/opencomputers/connect/), use the commands below.
3. Check outbound HTTPS and WebSocket access to `api.miosa.ai` on port 443; an HTTP health check alone does not test WebSocket proxying.
4. Confirm the service runs as the user whose `~/.osa/open_computers.toml` contains the intended host configuration.
5. Check that the host has not been revoked, then confirm a fresh heartbeat in MIOSA.

```bash
systemctl status osa-opencomputers.service --no-pager
journalctl -u osa-opencomputers.service -n 50 --no-pager
```

Use `sudo` for logs if your account cannot read the system journal.
`osa opencomputers status` can help inspect configuration, but its session output describes the runtime queried by that command.
Confirm the actual service and control-plane heartbeat before concluding that a separate background process is offline.

## Key saved but no connection

`osa opencomputers login` saves a host key, and `connect` is an alias for that command.
The agent still has to start in host mode; saving the credential alone does not start the session.
Follow the [startup steps](/docs/opencomputers/connect/#4-start-the-host-session).
Do not substitute a platform API key for the host key.

## Identity rejected after reinstall

The machine's identity file must match the identity pinned when the host first connected.
Preserve `~/.osa/open_computers.ed25519`, along with the host configuration, during upgrades.
If the identity is lost, revoke the host and register a new one rather than copying another machine's identity or disabling verification.

## Registration fails

| Error | Cause |
|---|---|
| `402 plan_limit_reached` | Your plan's host limit is reached; the response carries `limit` and `current` |
| `422 name is required` | `name` is missing, empty, or over 64 characters |
| `501 open_computers_disabled` | OpenComputers is not enabled for this environment |

Check the plan's host allowance in [Billing and limits](/docs/opencomputers/billing/) before assuming a bug.

## Command fails or appears stuck

| Symptom | What to check |
|---|---|
| `cmd is required` | Send the `cmd` field to the exec endpoint; `command` is the field name on the newer `POST .../jobs` route, not on `/exec` |
| `409 host_not_connected` | The host is offline. Bring the agent up before dispatching |
| `422 invalid_command` | The command is empty or over 8192 characters |
| `422 invalid_args` | More than 256 arguments, or a non-string argument |
| `422 invalid_timeout` | The timeout is outside 1 to 3600 seconds |
| `502 dispatch_failed` | The session dropped while dispatching; check the agent, then retry once |

- **Permission denied or command unavailable:** run the same command locally as the agent user and check its permissions, working directory, PATH, and supported operations.
- **HTTP request remains open:** exec streams by default; inspect SSE events until `exec_result` or `exec_error`, or use `stream: false` for a short command.
- **Timeout or connection loss:** save the returned job ID, inspect the job and the local process, and establish the outcome before retrying.

```bash
curl --fail-with-body -sS \
  "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/exec/$JOB_ID" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

A timeout or a disconnected client is not proof that the process stopped.
Avoid retrying a deployment, payment, file mutation, or other operation with side effects merely because the client disconnected.

## Containers

| Symptom | What to check |
|---|---|
| `503 host_not_connected` | The container runtime is managed by the agent on the host; an offline host cannot create or start containers |
| `402 plan_limit_reached` | The container and compose slot budget is full; see [Billing and limits](/docs/opencomputers/billing/) |
| Stuck in `provisioning` | The host is pulling the image, or the image reference is not pullable by that host's runtime |
| `409` on start | A container only starts from `stopped` or `failed`; check `state` first |
| `last_error` set | The runtime rejected the container; read `last_error` before retrying |

Pulling a large image over a slow link can take minutes. Watch the host's disk and network with `miosa host metrics <host>` rather than recreating the container.

## Meshes

| Symptom | What to check |
|---|---|
| Peer stuck in `pending_key` | The host has not completed its key exchange; confirm the host is online and the agent is current |
| Peer `active` but traffic fails | The services on the other host may not be listening on the address you dialed, or a host firewall blocks the mesh interface |
| `422 mesh /24 is full` | The mesh has reached 253 members |
| `422 one or more hosts not found` | A host ID belongs to another organization or does not exist |

Use `miosa host mesh get <mesh>` and read `latest_handshake`, `rx_bytes`, and `tx_bytes` to tell "never connected" from "connected but no traffic".

## GitHub Actions runners

| Symptom | What to check |
|---|---|
| `422 GitHub API rejected the PAT` | The token lacks repository or organization runner permissions, or has expired |
| `422 GitHub repo/org not found` | The `repo_url` is wrong, or the token cannot see it. GitHub Enterprise Server URLs are not supported |
| `429 GitHub API rate limit exceeded` | GitHub throttled the registration call; wait and retry |
| Runner `offline` | The host is offline, or the runner process died. Use `miosa host gha-runner refresh <host> <runner>` |
| Runner `failed` | Read the runner events; a failed install is usually a missing dependency on the host |

A workflow that never schedules is usually a label mismatch: check that the workflow's `runs-on` labels match the runner's `labels`.

## Backups

| Symptom | What to check |
|---|---|
| `503` on trigger | The source host must be connected to take a snapshot |
| Snapshot `failed` | Read `error` on the snapshot; a path that disappeared or a permission change are the common causes |
| `422 snapshot has no chunks` | The snapshot did not complete; only `complete` snapshots restore |
| `503 target host not connected` | Restores are pushed by the target host's agent, so the target must be online |
| `403 cross-organization restore not allowed` | The target host is not in the same organization as the snapshot |

## Tunnel does not reach the application

1. On the host, confirm the application is running and responds on the intended local port.
2. Check the tunnel's configured `target_port` and the host's connection.
3. Open the returned `public_url`; do not construct a hostname yourself.
4. Confirm the viewer meets the tunnel's access policy.

| Proxy error | Meaning |
|---|---|
| `connection_refused` | Nothing is listening on `target_port` on the host |
| `target_port_not_allowed` | The port is outside the range the host agent permits |
| `tunnels_disabled_on_host` | Tunnels are disabled on that host |
| `too_many_concurrent_tunnels` | The host is at its concurrent tunnel limit |
| `502 host_offline` | The host dropped while the request was in flight |
| `503 tunnel paused` | The tunnel is in state `paused` |
| `401` with `WWW-Authenticate: Basic` | The tunnel is in `password` mode and the request did not carry credentials |

A public URL cannot make an unavailable local service healthy.
Do not change a private tunnel to public solely to troubleshoot authentication.

## Commands work but desktop does not

A headless host can execute commands without providing a desktop.
Verify the selected host advertises desktop support and has the required session and streaming backend.
Check the agent's current platform support; registering macOS or Windows does not guarantee a working desktop stream.
For a MIOSA-managed Computer, follow [desktop readiness](/docs/computers/fast-start/) instead of installing a desktop on an arbitrary host.

## Customer-cloud resources exist but placement is unavailable

Cloud infrastructure existing is only one onboarding step.
Verify provider acceptance, a successful live canary, and host readiness before expecting placement.
See the [BYOC overview](/docs/infrastructure/byoc/overview/) for the applicable gates.

## Information to include when asking for help

Include the host ID, the operation or job ID, a timestamp with timezone, the agent version, the OS and architecture, and the relevant error text.
State whether the command works locally as the agent user and whether the heartbeat is fresh.
Remove API keys, host keys, identity files, private URLs containing tokens, and sensitive command output from shared logs.

# Tunnels and exposing services

URL: https://miosa.ai/docs/opencomputers/tunnels
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/opencomputers/tunnels
Source: src/routes/docs/opencomputers/tunnels/+page.md
Description: Expose a port on a host at a MIOSA-managed address, choose who can reach it, and understand what a tunnel does and does not do.

# Tunnels and exposing services

A tunnel publishes a port on one of your hosts at a MIOSA-managed address.
The host keeps dialing out to MIOSA; MIOSA routes inbound requests back down that session to your service.

An outbound management session and a publicly reachable application tunnel are different things.
Connecting a host does not expose anything. A tunnel is an explicit, separate exposure with its own access policy.

## Create a tunnel

```bash
miosa host tunnel new <host> --port 3000 --slug my-app-dev --access organization
miosa host tunnel list <host>
miosa host tunnel get <host> <tunnel>
miosa host tunnel rm <host> <tunnel> --yes
```

| Flag | Meaning |
|---|---|
| `--port int` | Port on the host to expose |
| `--slug string` | Address name (default: generated) |
| `--access string` | Who may open it: `organization` (default) or `public` |

The same call over REST:

```bash
curl --fail-with-body -sS \
  -X POST "https://api.miosa.ai/api/v1/opencomputers/hosts/$HOST_ID/tunnels" \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"target_port":3000,"auth_mode":"tenant_only","slug":"my-app-dev"}'
```

| Field | Type | Required | Description |
|---|---|---|---|
| `target_port` | integer | Yes | Local port to expose, `1` to `65535` |
| `auth_mode` | string | No | `public` \| `tenant_only` \| `password` (default: `tenant_only`) |
| `slug` | string | No | Address name, 4 to 63 lowercase alphanumeric or hyphen characters |
| `target_host` | string | No | Host to dial from the agent (default: `127.0.0.1`) |
| `password` | string | No | Required in practice when `auth_mode` is `password`; hashed, never returned |

```json
{
  "id": "tun_abc",
  "host_id": "host_abc123",
  "slug": "my-app-dev",
  "target_port": 3000,
  "auth_mode": "tenant_only",
  "public_url": "https://<public-host>/t/my-app-dev",
  "enabled": true,
  "created_at": "2026-01-01T00:00:00Z",
  "updated_at": "2026-01-01T00:00:00Z"
}
```

Use the returned `public_url`. Do not construct a hostname yourself: the routing domain is set per environment, so read it from the response instead of hardcoding one.

## Change or disable a tunnel

```bash
miosa host tunnel new <host> --port 8080 --slug my-app-dev   # re-create with a new port or slug
```

Over REST, `PATCH /api/v1/opencomputers/hosts/{id}/tunnels/{tunnel_id}` changes a tunnel in place:

| Field | Type | Description |
|---|---|---|
| `state` | string | `active`, `paused`, or `revoked` |
| `auth_mode` | string | Change the access mode |
| `target_host` | string | Change the host the agent dials |
| `slug` | string | Change the address name |
| `rotate_slug` | boolean | Generate a new slug |
| `password` | string | Set a new password (re-hashed) |

`DELETE /api/v1/opencomputers/hosts/{id}/tunnels/{tunnel_id}` returns `204 No Content` and revokes the tunnel.

The response adds live counters you can use to check that traffic is flowing: `state`, `custom_domain`, `request_count`, `lifetime_bytes_ingress`, and `lifetime_bytes_egress`.

## Access modes

| Mode | Who can open it |
|---|---|
| `organization` | Members of your MIOSA organization only (CLI default) |
| `tenant_only` | The tenant that owns the host |
| `public` | Anyone with the URL (API default) |

A public URL cannot make an unavailable local service healthy, and it does not fix an authentication problem.
Confirm the service answers on the host's own port before you change a tunnel's access mode.

## Expose a device port

`miosa device expose` publishes a port for any device kind, including a host:

```bash
miosa device expose <device> 3000
```

Use the typed `miosa host tunnel` command when you want the fuller surface - list, get, access mode, and slug control.

## What a tunnel does not do

- It does not change who owns the application. Your service still runs on your machine, under your process supervision.
- It does not remove the need for the service to be listening. The tunnel reaches a port; it does not start anything.
- It does not make the traffic private in transit beyond the transport MIOSA terminates. Set the access mode and the application's own authentication to match the data you serve.

# Recovery Playbooks

URL: https://miosa.ai/docs/operations/recovery
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/operations/recovery
Source: src/routes/docs/operations/recovery/+page.md
Description: Symptom-first recovery procedures for deployments, domains, TLS, Docker Host hosts, sandboxes, and production rollback.

# Recovery Playbooks

Use these playbooks when a customer-visible workflow is unhealthy.

Diagnose before mutating anything, preserve the last known-good version, and make one bounded recovery change at a time.

## First five minutes

1. Resolve the exact Organization, Workspace, Project, and affected resource.
2. Record the public URL, deployment ID, active version ID, and current health state.
3. Test the public route from outside the runtime.
4. Separate build, runtime, route, DNS, and TLS failures.
5. Preserve the previous ready Version and any operation or idempotency ID.

Diagram:
flowchart TD
  A["Public URL fails"] --> B["DNS resolves?"]
  B -->|no| DNS["Correct records and verify propagation"]
  B -->|yes| C["TLS active?"]
  C -->|no| TLS["Inspect validation and certificate state"]
  C -->|yes| D["Route targets active Version?"]
  D -->|no| ROUTE["Repair route reconciliation"]
  D -->|yes| E["Healthy Runtime Instance?"]
  E -->|no| RUN["Reconcile from immutable Release"]
  E -->|yes| APP["Inspect application logs and health contract"]

## Deployment is down

| Check | Healthy proof | Recovery |
|---|---|---|
| Active Version | Exact expected version ID | Promote the last verified ready Version |
| Artifact | Running digest matches Release | Replace the runtime from the immutable Release |
| Runtime | Required instances are ready | Reconcile or replace failed instances |
| Route | Public URL reaches active Version | Reconcile routing after runtime readiness |
| Application | Health endpoint succeeds | Fix configuration or publish a corrected Release |

Do not rebuild an old Release to recover it.

Rollback should select an already verified Version while preserving the Deployment and domain identities.

## Domain remains pending

1. Copy the exact record type, host, target, and ownership token returned by MIOSA.
2. Remove conflicting records at the same hostname.
3. Disable DNS proxying until ownership verification completes.
4. Query the authoritative DNS provider, then public resolvers.
5. Retry verification only after the expected answer is visible.

For a wildcard such as `*.apps.example.com`, most providers expect the host field `*.apps`, not the complete hostname.

For an apex hostname, use the provider's supported ALIAS, ANAME, or flattened CNAME behavior when a normal CNAME is not permitted.

## TLS is not active

- Confirm DNS already resolves to the MIOSA verification target.
- Confirm the hostname is attached to only one Organization and Deployment.
- Check whether a restrictive CAA record blocks the certificate authority.
- Keep proxying disabled until verification and certificate provisioning finish.
- Do not repeatedly detach and reattach the hostname because that restarts validation.

## Docker Host host is unhealthy

1. Confirm the host record points to the expected appliance and organization.
2. Confirm the appliance agent, Docker Engine, and required persistent storage are healthy.
3. Confirm the immutable Release is available to the appliance.
4. Check the last deployment operation before starting another one.
5. Reconcile the desired Deployment instead of creating a duplicate Deployment.

If a request times out, first determine whether the remote build is still running.
Recover with the recorded operation ID or idempotency key instead of submitting the same build again.

## Sandbox preview fails

- Confirm the Sandbox is running.
- Confirm the application listens on `0.0.0.0`, not only `localhost`.
- Confirm the requested preview port matches the application port.
- Confirm the development process is still alive.
- Recreate the Preview only after proving the Sandbox process and port are healthy.

## Escalation evidence

Provide support with resource IDs, UTC timestamps, operation IDs, expected and observed states, the public hostname, and redacted error output.

Never include API keys, cookies, database credentials, private source, customer personal data, or raw environment files.

# Optimal

URL: https://miosa.ai/docs/optimal
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal
Source: src/routes/docs/optimal/+page.md
Description: Optimal is MIOSA's built-in agent. Chat with it to answer questions about your workspace, build on your own sandboxes and computers, and investigate problems.

Optimal is MIOSA's built-in agent.
You describe what you want in a chat, and Optimal answers from your live workspace, builds on a machine you choose, or investigates a problem.
Open it from **Optimal** in the console sidebar, at `/optimal`.

## What Optimal does

- **Answers** questions about your organization and workspace: what is running, what changed, how something is set up.
- **Builds** on a sandbox or computer: it writes files, runs commands, serves a live preview, and can publish what it built.
- **Investigates** a problem: it traces evidence, such as a failed deployment or an error in your logs, before it reaches a conclusion.
- **Asks before it acts**: steps that change your workspace wait for your approval unless you allow them.

Optimal works only inside your organization and workspace, with your permissions.
See [Isolation and permissions](/docs/optimal/isolation/).

## Brains: who does the work

Before the first message you pick the brain that answers the chat.

| Brain | Who pays | What runs |
|---|---|---|
| Optimal | Wallet credits | MIOSA's own model, with a 1M-token context |
| A harness | Your own account | Claude Code, Codex, OSA, and the other harnesses run on a machine |
| A saved agent | Your own account | An agent you built in Agent Studio, with its own instructions and tools |

The brain is locked after the first message.
To change it, start a new chat.
See [Brains and agents](/docs/optimal/brains/).

## Ask, Build, Investigate

Every chat is in one of three modes.

| Mode | What it does |
|---|---|
| Ask | Answers from live workspace context, without touching a machine |
| Build | Builds or changes something on a sandbox or computer |
| Investigate | Traces evidence before reaching a conclusion |

Investigate always runs on the Optimal brain.
See [Chats and modes](/docs/optimal/chats/).

## Pricing in one line

The Optimal brain costs $1.50 per 1M input tokens and $6.00 per 1M output tokens, paid from wallet credits where 1 credit is 1 cent.
A typical message is about 4 credits.
Machines Optimal uses are billed at their normal rate.
A harness or saved agent bills its model to your own account.
See [Pricing and usage](/docs/optimal/pricing/).

# Optimal Engine

URL: https://miosa.ai/docs/optimal-engine
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine
Source: src/routes/docs/optimal-engine/+page.md
Description: Optimal Engine is the self-hosted memory and knowledge engine behind a workspace - it keeps source evidence, builds reviewed memory, and returns cited context to people and agents over HTTP, a CLI, and MCP.

Optimal Engine is a memory and knowledge engine for a person, a team, or a company.
It keeps the sources you give it, turns them into memory that someone has reviewed, and returns cited context to people and agents.
It is open source under the Apache 2.0 license, at [github.com/Miosa-osa/OptimalEngine](https://github.com/Miosa-osa/OptimalEngine).

Optimal Engine is not the Optimal chat agent.
[Optimal](/docs/optimal/) is the agent you chat with in the console.
Optimal Engine is the store it remembers with: a server you run yourself, or a managed one on MIOSA.

## What it does

| Step | What the Engine does |
|---|---|
| Organize | Keeps a tree of organizations, workspaces, and typed nodes such as people, products, and projects |
| Capture | Stores raw text, files, chat sessions, Notion exports, and records pulled from apps such as Slack, GitHub, and Linear |
| Remember | Classifies each input, extracts claims, and promotes a claim to a fact only after review or a confidence rule |
| Retrieve | Searches with full-text ranking, adds vector search when an embedding model is set up, and returns context with its sources |
| Operate | Gives agents a daily brief, open loops, a protocol, and allow, ask, or deny rules for what they may do |
| Project | Writes the same state out as markdown files, wiki pages, workspace bundles, and an HTTP API |

The Engine does not write answers with a language model.
`ask` returns the context and the sources an answer should come from, and your agent or model writes the answer.

## Two ways to run it

| | Self-hosted | On MIOSA |
|---|---|---|
| Where it runs | Your machine, server, or container | A private machine in your MIOSA workspace |
| Who runs it | You: install, keys, backups, upgrades | MIOSA: provisioning, backups, upgrades, health checks |
| Search | Full-text, plus vector search with your own embedding model | Full-text |
| How you reach it | `http://127.0.0.1:4200` or your own domain | The **Memory** page, Optimal chat, the `miosa engine` commands, and machines in the workspace |
| Availability | Anyone, from the repository | Enabled per organization |

Self-hosting needs nothing from MIOSA.
See the [self-hosted quickstart](/docs/optimal-engine/quickstart/) or [Optimal Engine on MIOSA](/docs/optimal-engine/miosa/).

These pages describe Optimal Engine 0.3.10, API version `v1`.
Check what a running Engine reports with `GET /api/version`.

# Agents and workflows

URL: https://miosa.ai/docs/optimal-engine/agents-and-workflows
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/agents-and-workflows
Source: src/routes/docs/optimal-engine/agents-and-workflows/+page.md
Description: What Optimal Engine gives an agent - a boot briefing, open loops, a daily rhythm, an operating protocol, allow, ask, or deny rules, organization policy, scheduled analyses, webhooks, and action traces.

Optimal Engine does not run agents or call tools itself.
It is the memory and the rules an agent works from: what to read first, what is open, what it may do, and a record of what it did.
Any agent reaches it over HTTP, the `optimal` CLI, or the MCP server; see [CLI, SDKs and MCP](/docs/optimal-engine/cli-sdks-mcp/).

## Start of a session: boot

```bash
optimal boot -w default:notes
```

`GET /api/boot?workspace=` returns, in one call:

- today's date and the current rhythm note;
- loops that are overdue or due today;
- recent decisions and stale items;
- the brief and the operating protocol;
- the organization policy the workspace follows.

An agent should call it before anything else in a session.

## Daily operation

| Route | CLI | What it does |
|---|---|---|
| `GET /api/brief` | `optimal brief` | Ranked items that need a decision today |
| `GET /api/loops`, `POST /api/loops` | `optimal loops`, `optimal loops add` | Open loops: commitments, replies owed, follow-ups, payments, decisions needed |
| `POST /api/loops/extract` | `optimal loops extract` | Find new loops in recent sources |
| `POST /api/loops/:id/close`, `drop`, `reopen` | `optimal loops close` | Change a loop's state |
| `GET /api/rhythm/current` | `optimal today` | The daily, weekly, or monthly note |
| `GET /api/protocol`, `PUT /api/protocol` | `optimal protocol` | The protocol an agent follows in this workspace |

## Rules for what an agent may do

### Authority

Authority answers allow, ask, or deny for an action on a resource, such as reading, writing, exporting, erasing, or syncing.
Deny wins, and anything without a rule is denied.

```bash
optimal authority decide --action export --resource "optimal://default:notes/..." -w default:notes
```

| Route | What it does |
|---|---|
| `POST /api/authority/decide` | Ask for a decision |
| `GET /api/authority/effective` | The rules that apply to a subject |
| `POST /api/authority/requests` | Ask a person to approve an action |
| `/api/authority/policies`, `/api/authority/grants` | Manage rules and time-limited grants |

Turn it on with `OPTIMAL_AUTHORITY_MODE`: `off` by default, `observe` to record decisions without blocking, or `enforce`.

### Organization policy

`PUT /api/org-section` sets rules once for the organization.
Every workspace reads them through `GET /api/org-policy`, cannot change them, and receives them in `boot` and `assemble`.

### Pre-send check

`POST /api/signals/check` (`optimal check`) checks a draft message against its receiver and channel, and suggests a shorter version.

## Records of work

| Route | What it does |
|---|---|
| `POST /api/agent-actions`, `GET /api/agent-actions/:id` | Record an agent's action, and read it with its linked evidence |
| `POST /api/sessions/commit` | Store a finished chat as an episode; what it learned goes to claim review |
| `GET /api/viability` | A health report on the workspace as an operating system, with alerts |

## Scheduled analyses and jobs

The Engine runs six analyses on a schedule: `promises`, `workspace_population`, `meeting_archive`, `file_audit`, `storage_usage`, and `retention_sweep`.

| Route | What it does |
|---|---|
| `GET /api/analyses` | Their reports |
| `POST /api/analyses/run` | Run one now (`admin`) |
| `GET /api/jobs` | The job queue |
| `GET /api/jobs/dead`, `POST /api/jobs/dead/:id/replay` | Failed jobs, and retrying one |

## Webhooks and live updates

A subscription says what an agent or person wants pushed to them: anything in a workspace, one node, a topic, or one audience.
Create one with `POST /api/subscriptions`; it can be paused, resumed, and deleted.
The Engine pushes matching items over `GET /api/surface/stream`, a server-sent event stream, and to a webhook when the subscription's `metadata` has a `webhook_url`.
`POST /api/subscriptions/:id/test-webhook` sends a test delivery.

The Engine records workflow traces and can promote repeated ones into skill packages (`mix optimal.skills`).
Those are records for review and retrieval.
The Engine does not run a skill package as code, and it has no agent registry or delegation between agents.

# Optimal Engine API reference

URL: https://miosa.ai/docs/optimal-engine/api
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/api
Source: src/routes/docs/optimal-engine/api/+page.md
Description: The Optimal Engine HTTP API - base URL, keys, scopes, paging, rate limits, errors, and the main routes for workspaces, ingest, search, ask, memory, claims, and operations, with curl examples.

| | |
|---|---|
| Base URL | `http://127.0.0.1:4200/api` on a self-hosted Engine. `/v1/...` is an alias of `/api/...`. |
| On MIOSA | `https://api.miosa.ai/api/v1/engines/<engine id>/engine-api/api/...` with an Engine client key; see [Optimal Engine on MIOSA](/docs/optimal-engine/miosa/#call-the-engine-api) |
| API version | `v1` |
| Auth | `Authorization: Bearer <key>` or `X-API-Key: <key>` |
| Body | JSON with `Content-Type: application/json` |
| Errors | `{"error": "<code>"}`, sometimes with a `detail` |

The Engine has about 300 routes.
This page covers the ones most apps and agents use.
The complete list, with the grant each route needs, is generated from the router into [`docs/reference/api.md`](https://github.com/Miosa-osa/OptimalEngine/blob/main/docs/reference/api.md), and a test fails whenever the two disagree.

```bash
E=http://127.0.0.1:4200
K="Authorization: Bearer $OPTIMAL_ENGINE_API_KEY"
```

## Keys and errors

When `OPTIMAL_AUTH_REQUIRED=true`, every route needs a key, including `/api/health`.

| Status | `error` | When |
|---|---|---|
| 400 | `invalid_json`, `invalid_parameter`, `workspace_required` | The request is malformed, or a key limited to named workspaces did not name one |
| 401 | `missing_api_key`, `invalid_api_key`, `api_key_revoked`, `api_key_expired` | The key is missing or not usable |
| 403 | `workspace_scope_denied` | The key does not cover that workspace |
| 403 | `permission_scope_denied` | The key does not have the scope the route needs |
| 404 | `not found`, `workspace not found` | No such route, or a workspace of another tenant |
| 413 | `request_too_large` | The body is over 8 MB |
| 426 | `client_incompatible` | An `optimal` CLI or MCP server of another major version |
| 429 | `rate_limited` | Over the key's rate limit; the body has `retry_after_ms` |
| 503 | `busy` | The store is busy, for example right after boot; retry after `Retry-After` |

### Rate limits

Each key has its own budget per minute, set by the [size profile](/docs/optimal-engine/operations/#sizing): 1,200 requests a minute on the default `business` profile.
Requests without a valid key share their IP address's budget.
Every response carries `X-RateLimit-Limit`, `X-RateLimit-Remaining`, and `X-RateLimit-Reset`.
`/api/health`, `/api/status`, and `/api/metrics/prometheus` are not counted.

### Paging

List routes take `offset` and `limit` (1 to 200, default 50) and answer with:

```json
"pagination": {"offset": 0, "limit": 50, "total": 132, "has_more": true}
```

## Engine

| Route | Returns |
|---|---|
| `GET /api/health` | `status` (`up`, `degraded`, `down`), `checks`, `warnings`, and the release. `?full=true` runs ten store diagnostics for one workspace. |
| `GET /api/status` | The same, plus `api_version` |
| `GET /api/version` | `version`, `git_sha`, `build_timestamp`, `release_channel`, `api_version`, `expected_migration`, `capabilities` |
| `GET /api/metrics` | JSON counters, latencies, and size gauges |
| `GET /api/metrics/prometheus` | Prometheus text format |
| `GET /api/auth/whoami` | The key's own scopes and workspaces |

## Workspaces and nodes

### Create a workspace

`POST /api/workspaces`

```bash
curl -s -X POST $E/api/workspaces -H "$K" -H "Content-Type: application/json" \
  -d '{"slug": "sales", "name": "Sales"}'
```

| Field | Required | Meaning |
|---|---|---|
| `slug` | yes | Lowercase name, unique in the tenant |
| `name` | yes | Display name |
| `description` | no | |
| `external_id` | no | Your own id for this workspace, unique in the tenant |

`201` returns the workspace: `id` (`default:sales`), `tenant_id`, `slug`, `name`, `status`, `created_at`.
Errors: `400` for a missing or invalid slug or name, `409 slug_taken`, `409 external_id_taken`.

| Route | What it does |
|---|---|
| `GET /api/workspaces` | List workspaces, paged |
| `GET /api/workspaces/:id`, `PATCH /api/workspaces/:id` | Read or rename one |
| `POST /api/workspaces/:id/archive` | Archive it; its data is kept |
| `GET /api/workspaces/:id/config`, `PATCH ...` | Workspace settings |

### Create a node

`POST /api/nodes` with `{"name", "kind", "slug", "workspace", "description"}` answers `{"ok": true, "id", "slug", "kind"}`.
`kind` is one of the node kinds in [Concepts](/docs/optimal-engine/concepts/#topology).

## Ingest

`POST /api/ingest` stores text as a source.
See [Sources and ingestion](/docs/optimal-engine/ingestion/) for the fields, files, chat sessions, Notion, and connectors.

```bash
curl -s -X POST $E/api/ingest -H "$K" -H "Content-Type: application/json" \
  -d '{"workspace": "default:sales", "title": "Auth decision", "text": "Decided: refresh-token rotation ships in v2."}'
```

```json
{"ok": true, "signal_id": "...", "genre": "...", "type": "...", "entities": [], "source_package_id": "..."}
```

## Search

`GET /api/search?q=&workspace=&limit=&offset=&mode=&type=&as_of=`

```bash
curl -s "$E/api/search?q=refresh%20token&workspace=default:sales&limit=5" -H "$K"
```

```json
{
  "query": "refresh token",
  "results": [
    {
      "id": "...",
      "title": "Auth decision",
      "uri": "optimal://...",
      "content": "Decided: refresh-token rotation ships in v2.",
      "l0_abstract": "...",
      "score": 0.82,
      "workspace_id": "default:sales",
      "inherited": false
    }
  ],
  "pagination": {"offset": 0, "limit": 5, "total": 1, "has_more": false}
}
```

`mode=hybrid` answers `503 hybrid_unavailable` when no embedding model answers.
A bad `as_of` answers `400`.

| Route | What it does |
|---|---|
| `GET /api/grep?q=` | Matching chunks, with `intent`, `scale`, `modality`, `literal`, and `path` filters |
| `GET /api/read?uri=&tier=` | One item by its `optimal://` URI; `tier` is `l0`, `l1`, or `full` |
| `GET /api/recall/who`, `when`, `where`, `owns`, `actions` | Targeted recall over people, time, places, ownership, and actions |
| `GET /api/profile` | A workspace profile: ground truth, recent activity, and top entities |
| `GET /api/graph`, `/api/graph/hubs`, `/api/graph/clusters` | The knowledge graph |

## Ask and assemble

`POST /api/rag` returns context for one question; `GET /api/rag/stream` streams it as server-sent events.
`POST /api/assemble` returns a tiered context package for an agent.
See [Memory and retrieval](/docs/optimal-engine/memory-and-retrieval/#ask) for fields and responses.

```bash
curl -s -X POST $E/api/rag -H "$K" -H "Content-Type: application/json" \
  -d '{"query": "What did we decide about auth?", "workspace": "default:sales", "format": "markdown", "bandwidth": "small"}'

curl -N "$E/api/rag/stream?query=auth%20decision&workspace=default:sales" -H "$K"
```

## Memory

| Route | What it does |
|---|---|
| `POST /api/memory` | Store a memory: `{"content", "workspace", "is_static", "audience", "citation_uri", "metadata"}`. Answers `201` with the memory, its `version`, and `was_existing`. |
| `POST /api/memory/remember` | Store through the gate; answers `{"action", "memory", "pending_claim_id", "gate"}` |
| `GET /api/memory` | List; `q`, `audience`, `include_forgotten`, paging |
| `GET /api/memory/:id` | One memory |
| `GET /api/memory/:id/versions`, `/relations` | Its history and links |
| `POST /api/memory/:id/update`, `/extend`, `/derive` | A new linked version |
| `POST /api/memory/:id/forget` | Hide it |
| `DELETE /api/memory/:id` | Delete it |

## Claims

| Route | Scope |
|---|---|
| `GET /api/memory-core/claim-review` | `read` |
| `GET /api/memory-core/claims`, `/claims/:id` | `read` |
| `POST /api/memory-core/claims/:id/promote` | `claims:review` |
| `POST /api/memory-core/claims/:id/reject` | `claims:review` |

## Chat sessions

| Route | What it does |
|---|---|
| `POST /api/sessions/commit` | Store a chat; see [Sources and ingestion](/docs/optimal-engine/ingestion/#chat-sessions) |
| `GET /api/sessions` | Committed chats, newest first |
| `GET /api/sessions/:id` | One chat and the review state of what it learned |

## Operations

These need an `admin` key.

| Route | What it does |
|---|---|
| `POST /api/auth/keys`, `GET /api/auth/keys` | Mint and list keys |
| `POST /api/auth/keys/:id/revoke`, `DELETE /api/auth/keys/:id` | Revoke or delete a key |
| `POST /api/backup` | Take a backup now |
| `GET /api/backup/offsite` | Offsite backups |
| `POST /api/workspaces/:id/bundle`, `POST /api/bundles/import` | Export or import a workspace bundle |
| `GET /api/stores`, `GET /api/storage` | Stores, providers, and usage against the size profile |
| `/api/sync/*` | Replication; see [Operations](/docs/optimal-engine/operations/#replication) |

`/api/data` is a separate, smaller API for app records: collections, records, queries, and a change stream.
A key made for it can call nothing else.
The repository guide `docs/guides/app-data-api.md` describes it.

# Optimal Engine CLI, SDKs and MCP

URL: https://miosa.ai/docs/optimal-engine/cli-sdks-mcp
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/cli-sdks-mcp
Source: src/routes/docs/optimal-engine/cli-sdks-mcp/+page.md
Description: The optimal client CLI, the Engine's MCP server for Claude Code and Codex, the mix tasks for operators, and the TypeScript and Python clients - how to install each from the repository and point it at an Engine.

Every interface below talks to the same HTTP API, so a workspace looks the same from each.
All of them install from a checkout of [Miosa-osa/OptimalEngine](https://github.com/Miosa-osa/OptimalEngine).

| Interface | For | Where |
|---|---|---|
| `optimal` CLI (also `oe`) | People and agents in a terminal | `apps/cli` |
| MCP server | Agent clients such as Claude Code and Codex | `apps/mcp` |
| Mix tasks | Operators on the Engine's own machine | `lib/mix/tasks` |
| TypeScript client | Apps | `sdks/typescript` |
| Python client | Apps and scripts | `sdks/python` |

The clients and the MCP server are not published to npm or PyPI.
Build them from the repository as shown below.

## The optimal CLI

A single shell script that needs `sh`, `curl` 7.55 or newer, and `awk`.
It sends the key to curl on standard input, so the key never shows in a process list, and it never prints the key.

```bash
apps/cli/install.sh            # installs optimal and oe into /usr/local/bin or ~/.local/bin
optimal --version
```

### Point it at an Engine

Settings are read in this order, first match wins:

1. Flags: `--api <url>`, `--key-file <path>`, `-w <workspace>`, `--profile <name>`.
2. A named profile, from `--profile` or `OPTIMAL_PROFILE`.
3. Environment: `OPTIMAL_ENGINE_URL`, `OPTIMAL_ENGINE_API_KEY` or `OPTIMAL_ENGINE_API_KEY_FILE`, `OPTIMAL_WORKSPACE`.
4. The default profile, `~/.config/optimal/profile`.
5. `http://127.0.0.1:4200`.

A profile file holds the same settings:

```text
url=http://127.0.0.1:4200
key_file=/home/me/.config/optimal/key
workspace=default:notes
```

`optimal doctor` reports where each setting came from and whether the Engine answers.
On MIOSA, `miosa engine connect` writes this profile for you; see [Optimal Engine on MIOSA](/docs/optimal-engine/miosa/#from-a-terminal).

### Commands

| Group | Commands |
|---|---|
| Session | `boot`, `today`, `fires`, `brief`, `protocol`, `commitments` |
| Loops | `loops list`, `loops add`, `loops close`, `loops drop`, `loops reopen`, `loops extract` |
| Retrieve | `search` (`find`), `grep`, `assemble`, `read`, `ask` (`rag`), `reconstruct`, `memory`, `claims`, `review` |
| Record | `capture`, `aware`, `note`, `lesson`, `decision`, `task`, `close`, `remember` |
| Chats and policy | `session commit`, `session list`, `session show`, `policy`, `org-section` |
| Rules | `routing`, `authority effective`, `authority decide`, `authority request`, `authority export` |
| Setup and health | `init`, `size`, `viability`, `chain`, `check`, `analyses`, `jobs` |
| Engine | `status`, `health`, `version`, `doctor`, `url`, `workspaces`, `organizations`, `whoami` |
| Any route | `api  /api/<path> [json]` |

```bash
optimal capture "Decided: annual plans get two months free." -w default:notes --title "Pricing"
optimal search "annual plans" -w default:notes -n 5
optimal ask "What did we decide about pricing?" -w default:notes
optimal api GET /api/version
```

Common options: `-n` for a limit, `--as-of` for a point in time, `--mode lexical|hybrid|auto`, `--field a.b` to print one field, and `--raw` for unformatted JSON.

| Exit code | Meaning |
|---|---|
| 0 | Done |
| 1 | Failed |
| 64 | Wrong usage |
| 65 | The Engine's answer could not be read |
| 69 | The Engine did not answer |
| 77 | The key was refused (401 or 403) |
| 78 | A setting is wrong, the command was refused, or the client is too old (426) |

## MCP server

A stdio MCP server over the same API, for agent clients.
It needs Node 20 or newer.

```bash
cd apps/mcp
npm ci && npm run build
```

It reads the same settings as the CLI, from the environment or a profile, once when it starts.
Restart it after the key changes.

Register it with Claude Code:

```bash
claude mcp add --scope user \
  --env OPTIMAL_ENGINE_URL=http://127.0.0.1:4200 \
  --env OPTIMAL_ENGINE_API_KEY_FILE=/home/me/.config/optimal/key \
  --env OPTIMAL_WORKSPACE=default:notes \
  optimal-engine -- node /path/to/OptimalEngine/apps/mcp/dist/index.js
```

Give it a key with only what its agent needs, for example `read` and `write` on one workspace.

| Group | Tools |
|---|---|
| Operating loop | `boot`, `brief`, `protocol`, `loops_list`, `loops_add`, `loops_close` |
| Retrieve | `search`, `grep`, `ask`, `assemble`, `read`, `recall`, `profile`, `wiki_get`, `workspaces` |
| Record | `capture`, `record`, `close`, `add_memory`, `forget_memory` |
| Chats and policy | `session_commit`, `sessions_list`, `session_get`, `org_policy` |
| Rules and checks | `authority_decide`, `authority_effective`, `check_draft`, `viability`, `action_step`, `action_chain` |
| Rendering | `render_context`, `render_specs` |

## Mix tasks

On the Engine's own machine, a checkout has `mix optimal.*` tasks that work on the store directly.
Useful ones:

| Task | What it does |
|---|---|
| `mix optimal.auth` | Mint, list, revoke, and delete API keys |
| `mix optimal.bootstrap` | Compile, migrate, and load the sample workspace |
| `mix optimal.status`, `mix optimal.health` | Liveness, and ten store diagnostics |
| `mix optimal.ingest`, `mix optimal.ingest_workspace` | Ingest text or a folder |
| `mix optimal.import_notion` | Import a Notion export |
| `mix optimal.connector`, `mix optimal.pull` | Set up and run app connectors |
| `mix optimal.search`, `mix optimal.rag`, `mix optimal.assemble` | Read from the command line |
| `mix optimal.claims`, `mix optimal.facts` | Review claims and list facts |
| `mix optimal.backup`, `mix optimal.restore`, `mix optimal.migrate` | Operations; see [Operations](/docs/optimal-engine/operations/) |
| `mix optimal.embed_backfill`, `mix optimal.index` | Embed missing chunks, or reindex |
| `mix optimal.compliance` | Data export, erasure, legal holds, and retention |
| `mix optimal.conformance` | Run the conformance suite against a live Engine |

`docs/guides/mix-tasks.md` in the repository lists all of them.

## TypeScript client

```bash
cd sdks/typescript
npm install && npm run build
```

```ts

const engine = new OptimalEngine({
  baseUrl: "http://127.0.0.1:4200",
  apiKey: process.env.OPTIMAL_ENGINE_API_KEY,
  workspace: "default:notes",
});

await engine.ingest("Decided: annual plans get two months free.", { title: "Pricing" });
const hits = await engine.search("annual plans");
const context = await engine.ask("What did we decide about pricing?");
console.log(context.envelope.body, context.envelope.sources);
```

It also has `grep`, `assemble`, `profile`, `createNode`, and sub-clients for `memory`, `workspaces`, `wiki`, `recall`, `subscriptions`, `surface`, and `render`.
Adapters for the Vercel AI SDK and the OpenAI Agents SDK are at `@optimal-engine/client/adapters/ai-sdk` and `/adapters/openai-agents`.

## Python client

```bash
pip install ./sdks/python
```

```python
from optimal_engine import OptimalEngine

engine = OptimalEngine(base_url="http://127.0.0.1:4200", workspace="default:notes", api_key="oe_...")
results = engine.search("annual plans")
memory = engine.memory.create(content="Customer Example Co renews in March.")
```

It needs Python 3.10 or newer, and has a sync `OptimalEngine` and an async `AsyncOptimalEngine`.
It covers search, grep, recall, memory, and workspaces.

In the current Python client, `ask()` reads the answer from the wrong field and returns an empty `body`.
Call `POST /api/rag` directly, or use the TypeScript client, until it is fixed.

# Optimal Engine concepts

URL: https://miosa.ai/docs/optimal-engine/concepts
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/concepts
Source: src/routes/docs/optimal-engine/concepts/+page.md
Description: The objects Optimal Engine is built from - tenants, workspaces, nodes, signals, source packages, claims, facts, memories, context packages, and projections - and how a source becomes reviewed memory.

Optimal Engine keeps three things apart: the evidence you gave it, the truth that was accepted from that evidence, and the views it builds for a reader.
Every object below belongs to one of those three.

## Topology

```text
Tenant / Organization
  -> Workspaces
      -> Nodes
          -> sources, signals, memories, wiki pages
```

| Object | What it is |
|---|---|
| Tenant / Organization | The top scope. It owns workspaces and holds the organization policy every workspace reads. |
| Workspace | One walled section with its own nodes, sources, memories, loops, and rhythm. A key can be limited to some workspaces. |
| Node | A typed thing inside a workspace. |
| Node relationship | A typed link between two nodes. |

A workspace id is `<tenant>:<slug>`, for example `default:sales` for the workspace `sales` in the `default` tenant.
The workspace `default` always exists.

Node kinds, as `POST /api/nodes` accepts them: `unit`, `team`, `project`, `entity`, `domain`, `department`, `operation`, `learning`, `person`, `product`, `partnership`, `context`.

Each new workspace also gets the standard node types the setup and topology tools use: `entity`, `division`, `department`, `team`, `role`, `project`, `process`, `task`, `operation`, `learning`, `person`, `customer`, `product`, `partnership`, `context`.

Relationship types: `parent_child`, `depends_on`, `blocks`, `references`, `collaborates_with`, `sequence_before`, `instance_of`, `owns`, `participates_in`, `supports`.

A project is only one kind of node.
Model ongoing work, such as hiring or support, as an `operation` node instead.

## From a source to memory

```text
source -> signal -> claim -> fact -> context package
```

| Object | What it is |
|---|---|
| Source package | The raw input, kept with its metadata, trust label, and retention state. It is never rewritten. |
| Signal | The classified unit the Engine works on. |
| Context | The indexed unit search returns: a signal, a resource, a memory, or a skill file. |
| Claim | An assertion the Engine found in a source, with a link back to it. A claim is pending until it is reviewed. |
| Fact | An accepted claim, with its evidence, confidence, precision, and the time it is valid for. |
| Memory object | The meaning around facts, sources, and time, such as an episode from a chat session. |
| Derivation ledger | The record of which source each claim, fact, and memory came from. |

### Signals

Every input is classified on five separate dimensions:

```text
Signal = Mode + Genre + Type + Format + Structure
```

Keeping them separate lets the Engine route, parse, and retrieve a meeting transcript differently from a spec or a code file.
Classification is rule-based and runs without a language model.

### Claims and facts

The Engine never treats an extracted sentence as true on its own.
A claim becomes a fact in one of two ways:

- A person or key with the `claims:review` grant promotes it.
- The workspace's promotion rule promotes it automatically.

The rule is set with `OPTIMAL_CLAIM_PROMOTION_MODE`:

| Mode | Behavior |
|---|---|
| `auto_threshold` (default) | Promotes a claim whose score reaches the workspace threshold, 0.85 by default |
| `manual` | Every claim waits for review |
| `agent_review` | Currently behaves like `manual` |

A promoted claim is kept and marked `promoted`, so the evidence trail stays complete.
A newer fact can supersede an older one, and the older one stays readable as history.

### Versioned memories

Alongside the claim lifecycle, the Engine keeps a simpler memory store you write to directly with `POST /api/memory`.
Each memory has versions, and memories link to each other with `updates`, `extends`, `derives`, `contradicts`, or `cites`.
Forgetting a memory hides it without deleting it; deleting is a separate, permanent call.

`POST /api/memory/remember` is the gated way in: it scores a new memory for novelty and salience, then adds it, updates a similar one, skips it, or proposes it as a claim.

## Reading the memory

| Object | What it is |
|---|---|
| Context package | What one reader may see for one task: the facts and memories used, their sources, confidence, and validity. It is a view, not truth. |
| Active memory pool | A working memory for one task, with the observations made during it. |
| Retrieval strategy | `tiered`, `reconstructive`, or `hybrid`. See [Memory and retrieval](/docs/optimal-engine/memory-and-retrieval/). |

## Projections

The Engine's database is the source of truth.
Everything else is a projection of it:

- **Workspace files**: each workspace has a folder with `nodes/`, `.wiki/`, `assets/`, and `architectures/`. Editing a file there comes back in as a new source, not as a direct change to the truth.
- **Wiki pages**: curated pages with citations, kept in `.wiki/`.
- **Workspace bundles**: a whole workspace exported as one file and imported into another Engine.
- **The API, CLI, and MCP server**: the same state, read by people and agents.

## Governance

| Object | What it is |
|---|---|
| API key | Identifies the caller. It carries scopes and a list of workspaces it may use. |
| Authority | Allow, ask, or deny rules for reading, searching, writing, exporting, erasing, and syncing. Deny wins. It runs in `off`, `observe`, or `enforce` mode. |
| Organization policy | Rules set once for the organization that every workspace reads and cannot change. |
| Security labels and partitions | Labels such as `confidential` on rows, and the partitions a key may read. |

The API uses the same names as this page: `workspace`, `node`, `claim`, `memory`, `context_package`.
URIs in results use the `optimal://` scheme.

# Sources and ingestion

URL: https://miosa.ai/docs/optimal-engine/ingestion
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/ingestion
Source: src/routes/docs/optimal-engine/ingestion/+page.md
Description: Every way to get data into Optimal Engine - text, files, chat sessions, Notion exports, batch imports, and apps such as Slack, GitHub, and Linear - with the file types it parses and the limits that apply.

Every input is kept as a source package first, then classified, split into chunks, indexed, and mined for claims.
The original is never rewritten, so every fact can point back to the source it came from.

## Ways in

| Input | Route or command |
|---|---|
| Text | `POST /api/ingest`, `optimal capture`, `mix optimal.ingest` |
| A file | `POST /api/assets` with the bytes as base64 |
| A folder of files | `mix optimal.ingest_workspace` |
| A finished chat | `POST /api/sessions/commit`, `optimal session commit` |
| A durable memory | `POST /api/memory`, `POST /api/memory/remember`, `optimal remember` |
| A Notion export | `POST /api/import/notion`, `mix optimal.import_notion` |
| Many records at once | `POST /api/batch/import/signals`, `POST /api/batch/import/memories` |
| An app | Connectors, below |
| Another Engine's workspace | A workspace bundle; see [Operations](/docs/optimal-engine/operations/#move-a-workspace) |

## Text

```bash
curl -s -X POST http://127.0.0.1:4200/api/ingest \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace": "default:notes",
    "title": "Pricing decision",
    "text": "Decided: annual plans get two months free from March.",
    "node": "pricing",
    "extract_claims": true
  }'
```

| Field | Required | Meaning |
|---|---|---|
| `text` | yes | The content |
| `workspace` | no | Workspace id; `default` when left out |
| `title` | no | Title shown in results |
| `genre` | no | Override the genre the Engine would pick |
| `node` | no | Node slug the source belongs to |
| `extract_claims` | no | `true` by default |

The response is `{"ok": true, "signal_id", "genre", "type", "entities", "source_package_id"}`.
A missing `text` answers `400`; a source the pipeline cannot take answers `422` with `ok: false` and an `error`.

## Files

`POST /api/assets` takes a file as `content_base64` with its filename.
The Engine stores the bytes, hashed, under the workspace's `assets/` folder, or in S3-compatible storage when `OPTIMAL_ASSET_STORAGE=s3`.

| Kind | Extensions | Text comes from |
|---|---|---|
| Markdown and text | `.md` `.txt` `.rst` `.adoc` `.log` | the file |
| Data | `.yaml` `.yml` `.toml` `.json` `.csv` `.tsv` | the file |
| Web | `.html` `.htm` `.xhtml` | the file |
| Code | about 37 languages, such as `.ex` `.py` `.js` `.ts` `.go` `.rs` `.java` `.sql` | the file |
| Office | `.docx` `.pptx` `.xlsx` | the file |
| PDF | `.pdf` | `pdftotext` |
| Images | `.png` `.jpg` `.jpeg` `.gif` `.webp` `.svg` | `tesseract`, plus a description from the vision model |
| Audio | `.mp3` `.wav` `.m4a` `.ogg` `.flac` | a whisper.cpp server |
| Video | `.mp4` `.mov` `.webm` `.mkv` | `ffmpeg` keyframes and audio |

An unknown extension is read as plain text.
When a tool is missing, the file is kept with its metadata and a warning such as `ffmpeg not on PATH`, and you can parse it again later.

## Chat sessions

Commit a finished conversation so its lessons become memory:

```bash
curl -s -X POST http://127.0.0.1:4200/api/sessions/commit \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace": "default:notes",
    "correlation_id": "chat-2026-10-23-01",
    "title": "Renewal planning",
    "messages": [
      {"role": "user", "content": "When is the supplier renewal?"},
      {"role": "assistant", "content": "The call moved to the 14th."}
    ],
    "learned": ["The supplier renewal call is on the 14th."]
  }'
```

The chat is stored as an episode.
Each `learned` item, up to 50, becomes a proposed claim in the review queue.
The response (`201`) has the `session_id`, its `uri`, the `summary`, and the `message_count`.
Read sessions back with `GET /api/sessions` and `GET /api/sessions/:id`.

## Notion exports

Export a Notion workspace as **Markdown & CSV**, then send the zip:

```bash
mix optimal.import_notion ./notion-export.zip --workspace default:notes
```

Over HTTP, `POST /api/import/notion` takes the zip as the request body and starts a job; follow it with `GET /api/import/notion/:job_id`.
Each page, database, and row becomes its own item with an `optimal://<workspace>/notion/<id>` URI, and page hierarchy and links become graph edges.
The importer checks sizes before it unpacks anything, refuses ZIP64 archives, and never turns an entry name into a path on disk.

## Apps (connectors)

A connector pulls records from an app on a schedule and stores them as sources.
It only reads; nothing is written back to the app.

| Group | Apps |
|---|---|
| Mail, files, and docs | Gmail, Google Drive, Notion, Dropbox, OneDrive, Confluence, a local sources folder |
| Chat and meetings | Slack, Microsoft Teams, Zoom, Fathom |
| Work tracking and code | GitHub, Linear, Jira |
| CRM and business | HubSpot, Salesforce, HighLevel, Stripe |
| Publishing and forms | beehiiv, Jotform |

Set `CONNECTOR_KEY` before you add one: it encrypts the app keys the Engine stores.

```bash
mix optimal.connector list
mix optimal.pull
```

Over HTTP, `GET` and `POST /api/connectors` list and add connectors, and `POST /api/connectors/:id/run` runs one now.
`docs/guides/connectors.md` in the repository lists what each one pulls and how it signs in.
Pulled records are stored as database rows with `optimal://connectors/<kind>/<id>` URIs, not as files, unless the connector is set to write files.

Every connector pulls the records its guide lists.
Downloading every attachment and binary file is not complete for every app yet.

## Limits

| Limit | Value |
|---|---|
| JSON request body | 8 MB |
| Import file | 1 GiB (`OPTIMAL_IMPORT_MAX_BYTES`) |
| Workspace bundle | 5 GiB (`OPTIMAL_BUNDLE_MAX_BYTES`) |
| Text sent to the embedding model | 6,000 characters per chunk |
| Learned items per chat session | 50 |

| Erlang/OTP | 27 or newer. Avoid OTP 28.0 to 28.2; the Docker image uses 28.5. |
| Elixir | 1.17 or newer |
| Build tools | git, a C toolchain, CMake. The image also installs zlib, zstd, lz4, bz2, snappy, and SQLite headers. |
| macOS | `brew install snappy` |
| Embeddings (optional) | [Ollama](https://ollama.com) with `nomic-embed-text`, or any OpenAI-compatible embeddings endpoint |
| Media parsing (optional) | `pdftotext` for PDF, `tesseract` for image text, `ffmpeg` for video, a whisper.cpp server for audio |

Without an embedding model the Engine still works: search is full-text only, and a backfill embeds everything once a model is set up.
Without a media tool, a file of that kind is stored with its metadata and a warning instead of its text.

## Install

### From a checkout

```bash
git clone https://github.com/Miosa-osa/OptimalEngine.git
cd OptimalEngine
mix deps.get
mix optimal.auth mint --name "root" --workspace '*'
OPTIMAL_API_ENABLED=true OPTIMAL_AUTH_REQUIRED=true mix run --no-halt
```

`make bootstrap` (or `mix optimal.bootstrap`) compiles, runs migrations, and loads the bundled `sample-workspace/` so you have data to try.

### With Docker

`deploy/Dockerfile.engine` builds an OTP release on Elixir 1.19.5 and OTP 28.5.

| Image default | Value |
|---|---|
| User | `optimal`, UID 1000, not root |
| Data | `/data`, the only volume. The database is `/data/.optimal/index.db`. |
| Port | `4200`, bound to `0.0.0.0` inside the container |
| API | On, with keys required (`OPTIMAL_AUTH_REQUIRED=true`) |
| Embeddings | `OLLAMA_HOST=http://host.docker.internal:11434` |
| Health check | `GET /api/health` with `Authorization: Bearer $OPTIMAL_ENGINE_API_KEY` |

Set `OPTIMAL_ENGINE_API_KEY` on the container, or the health check runs without a key and the container reports unhealthy.
On Linux, `host.docker.internal` does not resolve by default; point `OLLAMA_HOST` at the host's address.

### With Docker Compose

```bash
cd deploy
cp env.example .env
# Set OPTIMAL_BOOTSTRAP_KEY and OPTIMAL_ENGINE_API_KEY to the same oe_ key.
docker compose up --build
```

Compose publishes the Engine on `127.0.0.1:4200` and keeps data in the `optimal_data` volume.
For a public server, add the production overlay, which puts Caddy with automatic TLS in front and keeps the Engine port private:

```bash
docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
```

Set `DOMAIN` and `LETSENCRYPT_EMAIL` in `.env` first.

`deploy/docker-compose.storage.yml` also starts Postgres, NATS, Valkey, Qdrant, and OpenBao.
In 0.3.10 the Engine only uses its S3-compatible storage from that set.
The others have no adapter yet and report `adapter_missing`.

### As a release

```bash
MIX_ENV=prod mix release optimal
OPTIMAL_API_ENABLED=true OPTIMAL_AUTH_REQUIRED=true _build/prod/rel/optimal/bin/optimal start
```

`bin/optimal maintenance <task>` runs maintenance with the API off; see [Operations](/docs/optimal-engine/operations/#upgrades).

## Settings

The Engine reads its settings from environment variables at boot.
An invalid value stops the boot with a message that names the variable.

### Server and keys

| Variable | Default | What it does |
|---|---|---|
| `OPTIMAL_API_ENABLED` | off (image: on) | Only the value `true` starts the HTTP API |
| `OPTIMAL_API_PORT` | `4200` | Port |
| `OPTIMAL_API_INTERFACE` | `127.0.0.1` (image: `0.0.0.0`) | Address to bind |
| `OPTIMAL_AUTH_REQUIRED` | `false` (image: `true`) | Require an API key on every request. Takes `true` or `false` only. |
| `OPTIMAL_BOOTSTRAP_KEY` | none | Registers a first key at boot, in the form `oe_<24 hex>_<secret of 32+ characters>`. Changing it rotates the key. |
| `OPTIMAL_BOOTSTRAP_SCOPES` | `read,write` | Scopes of the bootstrap key |
| `OPTIMAL_BOOTSTRAP_WORKSPACES` | `*` | Workspaces of the bootstrap key |
| `OPTIMAL_BOOTSTRAP_TENANT` | `default` | Tenant of the bootstrap key |
| `OPTIMAL_REFUSE_OPEN_NETWORK` | off | Refuse to start when bound beyond loopback with keys off |
| `OPTIMAL_OPEN_NETWORK_ACKNOWLEDGED` | off | You run keys-off behind a proxy that authenticates every request |
| `OPTIMAL_SIZE_PROFILE` | `business` | Size profile; see [Operations](/docs/optimal-engine/operations/#sizing) |

### Paths and storage

| Variable | Default | What it does |
|---|---|---|
| `OPTIMAL_ENGINE_ROOT` | the working directory (image: `/data`) | Root of the workspace folders |
| `OPTIMAL_ENGINE_DB` | `.optimal/index.db` | SQLite database file |
| `OPTIMAL_ENGINE_CACHE` | `.optimal/cache` | Cache, including stored embeddings |
| `OPTIMAL_BACKUP_DIR` | `backups/` next to the database | Where backups are written |
| `OPTIMAL_KNOWLEDGE_BACKEND` | `ets` | Graph projection: `ets` in memory, or `rocksdb` on disk |
| `OPTIMAL_ASSET_STORAGE` | filesystem | `s3` keeps uploaded file bytes in S3-compatible storage |
| `OPTIMAL_S3_ENDPOINT`, `OPTIMAL_S3_BUCKET`, `OPTIMAL_S3_ACCESS_KEY_ID`, `OPTIMAL_S3_SECRET_ACCESS_KEY` | none | S3, MinIO, R2, or Garage. Also `OPTIMAL_S3_REGION` (`us-east-1`) and `OPTIMAL_S3_PREFIX`. |

### Secrets

Each is 64 hex characters; generate one with `openssl rand -hex 32`.

| Variable | Needed when |
|---|---|
| `CONNECTOR_KEY` | You set up app connectors or replication peers. It encrypts their stored keys. |
| `OPTIMAL_AUTHORITY_KEY` | Recommended always. It protects the signing keys of authority grants. |
| `OPTIMAL_BACKUP_KEY` | You send backups offsite. It encrypts them. |

### Embeddings

| Variable | Default | What it does |
|---|---|---|
| `OLLAMA_HOST` | `http://localhost:11434` | Ollama server |
| `OPTIMAL_EMBED_MODEL` | `nomic-embed-text` | Embedding model, 768 dimensions |
| `OPTIMAL_EMBED_URL` | none | Another endpoint. A path ending in `/api/embed` speaks Ollama; anything else speaks OpenAI `/v1/embeddings`. |
| `OPTIMAL_EMBED_DIMENSIONS` | `768` | Vector size of that model |
| `OPTIMAL_EMBED_API_KEY` or `OPTIMAL_EMBED_API_KEY_FILE` | none | Key for that endpoint, read per request and never stored |
| `OPTIMAL_GENERATE_MODEL` | `qwen3:1.7b` | Small model used to curate wiki pages and summarize sessions |
| `OPTIMAL_VLM_MODEL` | `qwen2.5-vl` | Vision model that describes images |

### Behavior

| Variable | Default | What it does |
|---|---|---|
| `OPTIMAL_CLAIM_PROMOTION_MODE` | `auto_threshold` | `auto_threshold`, `manual`, or `agent_review`; see [Concepts](/docs/optimal-engine/concepts/#claims-and-facts) |
| `OPTIMAL_AUTHORITY_MODE` | `off` | `off`, `observe` (log decisions), or `enforce` |
| `OPTIMAL_ENGINE_SCOPE` | `org` | `workspace` limits the Engine to `OPTIMAL_ENGINE_WORKSPACE` |
| `OPTIMAL_IMPORT_MAX_BYTES` | 1 GiB | Largest import file |
| `OPTIMAL_BUNDLE_MAX_BYTES` | 5 GiB | Largest workspace bundle |
| `OPTIMAL_RELEASE_CHANNEL` | `dev` | `dev`, `stable`, `beta`, or `pinned`, as `/api/version` reports it |

`deploy/env.example` in the repository lists every variable with a comment.

## Where data lives

SQLite is the store.
It holds full-text search, vectors, and every record, so one file plus the folders around it is the whole Engine.

```text
<OPTIMAL_ENGINE_ROOT>/          workspace folders: nodes/, .wiki/, assets/
.optimal/index.db               the database (with -wal and -shm files)
.optimal/cache/                 cache and stored embeddings
.optimal/backups/               local backups
.optimal/knowledge-rocksdb/     graph projection, when the rocksdb backend is on
```

`GET /api/stores` lists the 13 logical stores and which provider backs each one.

A PostgreSQL store exists, but it needs a build compiled with `OPTIMAL_STORE=postgres`, and moving an existing Engine onto it is not supported yet.
The Docker image is SQLite only.
Run `mix optimal.postgres.check` to see its state on your build.

## API keys and scopes

Send a key as `Authorization: Bearer <key>` or `X-API-Key: <key>`.
Keys look like `oe_<id>_<secret>`; the Engine keeps only a bcrypt hash of the secret.

Mint keys from the checkout:

```bash
mix optimal.auth mint --name "agent" --workspace default:notes --scope read --scope write
mix optimal.auth list
mix optimal.auth revoke <id>
```

Or over HTTP with an `admin` key: `POST /api/auth/keys` with `{"name", "scopes", "workspace_scope", "expires_at"}`.
A key can only mint keys narrower than itself.
`GET /api/auth/whoami` shows a key's own scopes and workspaces.

| Scope | Allows |
|---|---|
| `read`, `write` | Reading and writing in the key's workspaces |
| `admin` | Keys, backups, maintenance, and other operator routes |
| `claims:review` | Promoting and rejecting claims |
| `topology:write` | Changing workspaces and nodes |
| `connectors:write` | Setting up app connectors |
| `sync` | Replication |
| `data:admin` | App data collections |
| `authority:read`, `authority:enforce`, `authority:approve`, `authority:issue`, `authority:admin` | Authority rules and grants |
| `*` | Everything |

With `OPTIMAL_AUTH_REQUIRED=false`, a request with no key acts as the local operator and can do anything.
That is fine on `127.0.0.1`.
Bound to any other address, the Engine logs an error at boot and every 10 minutes, and `/api/health` warns `auth_open_on_network`.
A tunnel or proxy in front of a loopback Engine is not detected, so turn keys on before you publish it.

# Memory and retrieval

URL: https://miosa.ai/docs/optimal-engine/memory-and-retrieval
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/memory-and-retrieval
Source: src/routes/docs/optimal-engine/memory-and-retrieval/+page.md
Description: How Optimal Engine searches (full-text, vector, hybrid), what ask and assemble return, how claims are reviewed into facts, how versioned memories work, and what the benchmark numbers mean.

Optimal Engine has four ways to read memory, from a plain search to a governed context package for an agent.

| Call | Returns | Use it for |
|---|---|---|
| `GET /api/search` | Ranked results with their sources | Finding things |
| `GET /api/grep` | Matching chunks, with intent, scale, and modality filters | Finding exact passages |
| `POST /api/rag` (`optimal ask`) | A context envelope sized for a reader, with sources | Giving a model what it needs to answer one question |
| `POST /api/assemble` (`optimal assemble`) | A tiered context package with reviewed facts and memories | Briefing an agent before it acts |

None of them writes an answer with a language model.
They return context and the sources it came from; your model writes the answer.

## Search

```bash
curl -s "http://127.0.0.1:4200/api/search?q=renewal&workspace=default:notes&limit=10&mode=auto" \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY"
```

| Parameter | Default | Meaning |
|---|---|---|
| `q` | required | Query |
| `workspace` | `default` | Workspace id |
| `limit`, `offset` | `10`, `0` | Paging |
| `mode` | `auto` | `auto`, `lexical`, or `hybrid` |
| `type` | all | `memory` searches only durable memories |
| `as_of` | now | ISO 8601 instant to measure recency against |

Each result has an `id`, `title`, `uri`, `content`, a short `l0_abstract`, a `score`, and the `workspace_id` it came from.
`inherited: true` marks a result that came from the organization policy rather than the workspace itself.

### How ranking works

- **Full-text**: SQLite FTS5 BM25, multiplied by a recency decay that depends on the kind of source and by a signal-quality score.
- **Vector**: cosine similarity over embeddings, when an embedding model is set up.
- **Hybrid**: a weighted mix of the two, then a boost for results connected in the graph.

| `mode` | Behavior |
|---|---|
| `auto` | Uses vectors when the embedding model answers, and full-text otherwise |
| `lexical` | Full-text only |
| `hybrid` | Requires vectors; answers `503 hybrid_unavailable` instead of quietly falling back |

Ties are broken by `uri` and then `id`, so the same query on the same data returns the same order.

Vectors are stored in SQLite and compared in the Engine process, without an approximate nearest-neighbor index.
Vector search time grows with the number of chunks, so watch `search_latency_ms` in [metrics](/docs/optimal-engine/operations/#observability) as a workspace grows.

## Ask

```bash
curl -s -X POST http://127.0.0.1:4200/api/rag \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "What did we decide about pricing?", "workspace": "default:notes", "format": "claude", "bandwidth": "small"}'
```

The Engine reads the intent of the question, looks for a curated wiki page first, searches when there is none, and fits the result to the reader.

| Field | Values |
|---|---|
| `format` | `plain`, `markdown`, `claude`, `openai` |
| `bandwidth` | `small`, `medium`, `large` |
| `strategy` | `tiered`, `reconstructive`, `hybrid` |
| `audience` | Who will read it, used to filter and shape the result |
| `context_package` | `true` returns a governed context package as well |

```json
{
  "source": "chunks",
  "envelope": {
    "body": "...",
    "format": "claude",
    "sources": ["optimal://..."],
    "warnings": []
  },
  "trace": {"intent": "...", "n_candidates": 12, "n_delivered": 4, "elapsed_ms": 41}
}
```

`source` says where the context came from: `wiki`, `chunks`, `memory`, `context_package`, or `empty`.
`GET /api/rag/stream` returns the same steps as server-sent events: `intent`, `wiki_hit` or `chunks`, `composing`, `envelope`, and `done`.

## Assemble and reconstruct

`POST /api/assemble` returns what an agent should read before acting: tiers `l0` to `l3`, the `total_tokens`, the `sources`, and a `context_package`.
The context package holds reviewed facts and memory objects only, so a new source shows up there after its claims are promoted.

`POST /api/reconstruct` uses the reconstructive strategy: it expands across associations between memories the reader is allowed to see.
Associations can improve recall, but they never decide what is true.
Record how useful a reconstruction was with `POST /api/reconstruct/:id/outcome`, which the Engine credits per workspace and intent.

## Reviewing claims

```bash
optimal claims -w default:notes
optimal review -w default:notes
```

| Route | What it does |
|---|---|
| `GET /api/memory-core/claim-review` | The review queue |
| `GET /api/memory-core/claims` | Claims, with their status and sources |
| `POST /api/memory-core/claims/:id/promote` | Accept a claim as a fact (`claims:review`) |
| `POST /api/memory-core/claims/:id/reject` | Reject a claim (`claims:review`) |

The default rule promotes a claim on its own when its score reaches the workspace threshold of 0.85.
Set `OPTIMAL_CLAIM_PROMOTION_MODE=manual` to review every claim yourself.

## Versioned memories

```bash
curl -s -X POST http://127.0.0.1:4200/api/memory/remember \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"workspace": "default:notes", "content": "Customer Example Co renews in March."}'
```

`remember` scores the memory first and answers with an `action`:

| `action` | Meaning |
|---|---|
| `add` | Stored as a new memory |
| `update` | Stored as a new version of a similar memory |
| `skip` | Already known; nothing changed |
| `pending_claim` | Proposed as a claim for review |
| `rejected` | Below the gate |

The `gate` object explains the score: `novelty`, `salience`, `prediction_error`, and `reason`.
`POST /api/memory` stores a memory without the gate.

| Route | What it does |
|---|---|
| `GET /api/memory` | List, with `q`, `include_forgotten`, and paging |
| `GET /api/memory/:id/versions` | The version chain |
| `GET /api/memory/:id/relations` | Links: `updates`, `extends`, `derives`, `contradicts`, `cites` |
| `POST /api/memory/:id/update`, `extend`, `derive` | A new linked version |
| `POST /api/memory/:id/forget` | Hide it; the row stays |
| `DELETE /api/memory/:id` | Delete it permanently |

## Time travel

`search`, `grep`, `ask`, and `assemble` take `as_of`, an ISO 8601 instant.
Facts carry the time they are valid for, and a superseded fact stays readable as history.

## Benchmarks

On LoCoMo, all 1,540 questions, the Engine's candidate portfolio retrieves at least one gold evidence item for 96.1% of questions and 87.1% of all gold evidence at top 100.
That measures retrieval, not answer accuracy.
The candidate portfolio is opt-in (`memory_search_mode=portfolio` on a memory search); the default memory search is `hybrid`.
The repository's README has the full results, their limits, and the commands that reproduce them under `benchmarks/`.

# Optimal Engine on MIOSA

URL: https://miosa.ai/docs/optimal-engine/miosa
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/miosa
Source: src/routes/docs/optimal-engine/miosa/+page.md
Description: Run a managed Optimal Engine on MIOSA - workspace Memory in the console, how Optimal chat uses it, the miosa engine commands, client keys for the optimal CLI and MCP server, the API, sizes, backups, and how to get it enabled.

On MIOSA, an Optimal Engine runs as a managed database with the engine `optimal`.
MIOSA creates and runs it for you: you never install it, hold its admin key, or take its backups by hand.

## Availability

Managed Engines are enabled per organization.
Until yours is enabled:

- the console's create flow under **Databases** does not offer Optimal Engine;
- **Start Memory** answers "Memory could not be started. Your role may not allow it, or Memory is not set up for this organization yet.";
- creating one over the API or CLI answers `422` with the code `ENGINE_NOT_AVAILABLE`.

To have it turned on, open a ticket from the console or email [support@miosa.ai](mailto:support@miosa.ai) with your organization's name.
See [Support](/docs/faq/support/).
Self-hosting needs no enablement; see the [quickstart](/docs/optimal-engine/quickstart/).

## What you get

| Part | Detail |
|---|---|
| Machine | A private machine in your workspace's network, reachable only inside MIOSA and through the MIOSA API |
| Data | A durable data disk that survives restarts and upgrades |
| Keys | MIOSA holds the Engine's admin key and never shows it; you mint short-lived client keys |
| Workspaces | An Engine workspace named after each MIOSA workspace attached to it |
| Backups | Scheduled backups of the whole data disk, and backups on demand |
| Health | Health checks reported by the Engine itself |
| Search | Full-text search. Managed Engines do not include an embedding model, so vector search is not available on MIOSA. |

It is billed like an always-on managed database while it runs, at the hourly price of its size.
The console shows that price, and the price for a full month, before it creates anything.

## Workspace Memory in the console

**Optimal > Memory** (`/optimal/memory`) is the simplest way in.
Memory belongs to one workspace: pick a workspace in the switcher first.

1. Press **Start Memory**.
   - If your organization already has a running Engine, Memory attaches this workspace to it at no new cost.
   - Otherwise the console offers to create one with 1 vCPU, 2 GiB of memory, and the smallest disk, and shows its price. Press **Create and start Memory**.
2. "Memory is starting. This takes about a minute."
3. When it is running, the page has a search box over everything the workspace knows, with each result's title, location, and an excerpt.

To add to Memory, ask Optimal in a chat to save a note.

## How Optimal chat uses Memory

When the workspace has Memory, [Optimal](/docs/optimal/) can:

- **search it** before answering about the workspace's people, projects, clients, or history, and say so when Memory has nothing;
- **save** a note, a decision, or a transcript you ask it to keep;
- **start** Memory for the workspace when you ask.

In an **All workspaces** chat, Optimal searches every workspace you can open and names the workspace each result came from.

Each chat also has a Memory panel:

- **Save to memory** stores the chat as a session.
- **Sources** lists what Optimal read, grouped by workspace in an organization chat.
- **Learned in this chat** lists the claims the chat produced; accept or reject each one.

Optimal reaches Memory through MIOSA as you, with your permissions.
It holds no Engine key and has no network path to the Engine.
What Memory returns is passed to the model as untrusted content.

## From a terminal

The [MIOSA CLI](/docs/cli/) has a `miosa engine` command group, version 2.3.19 or newer.

```bash
miosa engine create brain --workspace notes --for workspace --wait
miosa engine list
miosa engine status notes
```

`create` returns the existing Engine when one with that name exists, so scripts can call it every time.
`--for` picks a starting size: `agent` (tiny, 2 GiB disk), `workspace` (xs, 10 GiB), or `business` (small, 25 GiB).
`--size tiny|xs|small|medium|large` and `--disk ` override it.
An Engine created for a workspace attaches to that workspace when it first runs.

| Command | What it does |
|---|---|
| `miosa engine attach <workspace> --to <engine>` | Attach another workspace to an Engine |
| `miosa engine detach <workspace>` | Detach a workspace and revoke its Engine key |
| `miosa engine status [workspace]` | Which Engine serves a workspace, or every Engine and its workspaces |
| `miosa engine connect <engine>` | Mint a client key and write an `optimal` CLI profile |
| `miosa engine shell <engine> [-- command]` | Run a shell or a command with a key that is revoked when it exits |
| `miosa engine backup <engine>`, `miosa engine backups <engine>` | Take a backup now, or list backups |
| `miosa engine recover <engine>` | Restore a backup over the Engine, or with `--to-new <name>` into a new one |
| `miosa engine upgrade <engine> --to <version>`, `miosa engine rollback <engine>` | Change the Engine version |
| `miosa engine rm <engine>` | Delete the Engine and its data disk |

### Use the optimal CLI and MCP server

`miosa engine connect` mints a read/write key for one of the Engine's workspaces and writes `~/.config/optimal/profile` with mode `0600`.
The [`optimal` CLI and MCP server](/docs/optimal-engine/cli-sdks-mcp/) read that profile, so they reach the managed Engine with no other setup.

```bash
miosa engine connect brain                       # key lasts 24 hours
miosa engine connect brain --workspace notes --profile notes --ttl 72h
optimal boot
optimal search "renewal"
miosa engine shell brain -- optimal brief        # one command, key revoked after
```

`--print` prints shell exports instead of writing a profile.
Keys last 24 hours by default and at most 30 days.

## Machines in the workspace

Sandboxes, computers, apps, and agents in a workspace attached to an Engine start with two variables:

| Variable | Value |
|---|---|
| `OPTIMAL_ENGINE_URL` | The Engine's private address, on port 4200 |
| `OPTIMAL_ENGINE_API_KEY` | A key limited to that workspace |

The `optimal` CLI and the MCP server read both, so an agent on the machine can call `optimal boot` straight away.
A machine still starts when the Engine is down.

## Call the Engine API

From outside the workspace, call the Engine through MIOSA with a client key.

1. Mint a client key. Only an organization owner or admin can mint one.

   ```bash
   curl -s -X POST https://api.miosa.ai/api/v1/databases/$ENGINE_ID/client-keys \
     -H "Authorization: Bearer $MIOSA_API_KEY" \
     -H "Content-Type: application/json" \
     -d '{"workspace_id": "your_workspace_id", "ttl_seconds": 86400}'
   ```

   `201` returns `data.key` once, with its `id` and `expires_at`.
   The workspace must be attached to the Engine.
   `GET /databases/:id/client-keys` lists keys without their secrets, and `DELETE /databases/:id/client-keys/:key_id` revokes one.

2. Call the Engine with it:

   ```bash
   curl -s "https://api.miosa.ai/api/v1/engines/$ENGINE_ID/engine-api/api/search?q=renewal" \
     -H "Authorization: Bearer $ENGINE_CLIENT_KEY"
   ```

The proxy forwards only the routes an agent needs, and answers `404` for everything else, including key, sync, backup, and maintenance routes.

| Method | Routes under `/api/` |
|---|---|
| `GET` | `boot`, `brief`, `protocol`, `operating-projection`, `rhythm/current`, `loops`, `search`, `grep`, `read`, `memory`, `memory-core/claims`, `memory-core/claim-review`, `sessions`, `sessions/:id`, `org-policy`, `review/routing`, `routing/rules`, `authority/effective`, `viability`, `viability/history`, `analyses`, `jobs`, `workspaces`, `status`, `health`, `version`, `profile`, `recall/:kind`, `wiki/:slug`, `render/specs`, `agent-actions/:id` |
| `POST` | `rag`, `assemble`, `reconstruct`, `ingest`, `memory`, `memory/remember`, `memory/:id/forget`, `loops`, `loops/extract`, `loops/:id/:action`, `sessions/commit`, `routing/classify`, `signals/check`, `authority/decide`, `authority/requests`, `agent-actions`, `render/context` |

| Status | Code | When |
|---|---|---|
| 404 | `NOT_FOUND` | The route is not on the list |
| 409 | `ENGINE_NOT_RUNNING` | The Engine is stopped or starting |
| 413 | `REQUEST_TOO_LARGE` | The body is over 1 MiB, or the query string over 8 KiB |
| 502 | `ENGINE_UNAVAILABLE`, `ENGINE_RESPONSE_TOO_LARGE` | The Engine did not answer, or answered too much |

### Workspace Memory routes

These use your MIOSA API key, not a client key, and reach the Engine that serves the workspace.

All paths start with `https://api.miosa.ai/api/v1/workspaces/:workspace_id/engine`.

| Route | What it does | Permission |
|---|---|---|
| `GET .../engine` | Which Engine serves the workspace | |
| `GET .../engine/search?q=&limit=` | Search the workspace's Memory | `databases:read` |
| `GET .../engine/boot` | The workspace's boot briefing | `databases:read` |
| `POST .../engine/remember` with `{"content", "metadata"}` | Save a memory | `databases:write` |
| `POST .../engine/sessions` with `{"correlation_id", "messages", "title"}` | Save a chat as a session | `databases:write` |
| `GET .../engine/sessions/:session_id` | Read a saved chat | `databases:read` |
| `POST .../engine/claims/:claim_id/accept` or `/reject` | Review a claim | `databases:write` |

A workspace with no Engine answers `404 NOT_FOUND`; an Engine that is not running answers `409 ENGINE_NOT_RUNNING`.

## Backups, upgrades, and size

Open the Engine under **Databases** in the console.
Its page has an **Overview** tab with the connection, health, and usage against the size's limits, a **Backups** tab, a **Resize** button, and, when the Engine reports them, **Brief**, **Loops**, **Workspaces**, and **Keys** tabs.

| Size | vCPU | Memory | Disk |
|---|---|---|---|
| `agent` | 1 | 1 GiB | 2 GiB |
| `workspace` | 1 | 2 GiB | 10 GiB |
| `business` | 2 | 4 GiB | 25 GiB |
| `platform` | 4 | 8 GiB | 100 GiB |
| `scale` | 8 | 16 GiB | 250 GiB |

Resizing moves between `workspace`, `business`, `platform`, and `scale`; `agent` is a starting size only.
A resize refuses a size whose disk or memory cannot hold what the Engine already uses, and restarts a running Engine.
Over the API, `POST /api/v1/databases/:id/resize` takes `{"size": "business"}`, and `"dry_run": true` returns the plan without changing anything.

`miosa engine recover --to-new` restores a backup into a new Engine and never touches the original.
Restoring over the Engine keeps the previous data aside; `GET /api/v1/databases/:id/restore-copies` lists those copies.

A managed Engine is the same software as a self-hosted one, so the [API](/docs/optimal-engine/api/), the [CLI](/docs/optimal-engine/cli-sdks-mcp/), and the [concepts](/docs/optimal-engine/concepts/) apply to both.

# Operate a self-hosted Optimal Engine

URL: https://miosa.ai/docs/optimal-engine/operations
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/operations
Source: src/routes/docs/optimal-engine/operations/+page.md
Description: Backups and restore, upgrades and migrations, size profiles and rate limits, replication between Engines, moving a workspace, erasure and retention, and metrics for a self-hosted Optimal Engine.

This page is for a self-hosted Engine.
On MIOSA, backups, upgrades, and resizing are done for you; see [Optimal Engine on MIOSA](/docs/optimal-engine/miosa/#backups-upgrades-and-size).

## Backups

A backup is an online copy of the SQLite database, taken with `VACUUM INTO` while the Engine keeps serving.

```bash
mix optimal.backup /var/backups/engine-$(date +%F).db --verify
```

`--verify` runs an integrity check on the copy.
Over HTTP, an `admin` key can call `POST /api/backup` with an optional `{"name"}`; the file is written in the backup folder and the response has its `path`, `size_bytes`, `checksum_sha256`, and `integrity_status`.

### Offsite backups

With `OPTIMAL_BACKUP_KEY` and the `OPTIMAL_S3_*` settings, backups can be encrypted and sent to S3-compatible storage:

```bash
mix optimal.backup /tmp/snapshot.db --offsite
mix optimal.backup --list-offsite
```

Set `OPTIMAL_OFFSITE_BACKUP_INTERVAL_MS` (60000 or more) to take them on a schedule.
The Engine keeps the newest 14 offsite and 3 local copies by default (`OPTIMAL_OFFSITE_BACKUP_KEEP`, `OPTIMAL_OFFSITE_BACKUP_KEEP_LOCAL`).

### Restore

Stop the Engine first.

```bash
mix optimal.restore /var/backups/engine-2026-10-23.db
mix optimal.restore --from-offsite <backup id>
```

The restore checks the copy's checksum and integrity before it changes anything, and keeps the previous database beside it as `<db>.pre-restore-<time>`.

A backup is the database only.
Workspace folders under `OPTIMAL_ENGINE_ROOT`, local asset files, and the RocksDB graph folder are not in it; back them up with the volume or folder.
Local backups are not encrypted, and they contain the encrypted connector keys, so store them as secrets.
With Docker, the simplest full backup is the whole `/data` volume.

## Upgrades

1. Take a backup.
2. Install the new version: pull the new tag and rebuild, or start the new image on the same volume.
3. Start it. Migrations run at boot, each in its own transaction, before the API answers.

If a migration fails, it is rolled back, the Engine refuses to open the store, and it exits with `migration <number> failed and was rolled back: <cause>`.
Migrations that ran before it in the same boot stay applied, so going back means restoring the backup from step 1.

Check what is running and what it expects:

```bash
curl -s http://127.0.0.1:4200/api/version -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY"
mix optimal.migrate --status
```

`mix optimal.conformance --url <url> --key <key>` runs the conformance suite against a live Engine, prints a JSON report, and exits non-zero on any failure, so it can gate an upgrade.

A release build runs the same maintenance with the API off: `bin/optimal maintenance migrate`, `health`, `embed_backfill`, `graph_backfill`, `facts`, or `claims`.
It exits `0` when done, `1` on failure, and `78` when the Engine is in the wrong state for the task.

## Sizing

`OPTIMAL_SIZE_PROFILE` sets the rate limit per key and the advised limits the Engine measures itself against.

| Profile | Machine | Disk | Vectors | Memories | API requests per minute per key |
|---|---|---|---|---|---|
| `agent` | 1 vCPU, 1 GiB | 2 GiB | 50,000 | 100,000 | 300 |
| `workspace` | 1 vCPU, 2 GiB | 10 GiB | 250,000 | 500,000 | 600 |
| `business` (default) | 2 vCPU, 4 GiB | 25 GiB | 1M | 2M | 1,200 |
| `platform` | 4 vCPU, 8 GiB | 100 GiB | 5M | 10M | 3,000 |
| `scale` | 8 vCPU, 16 GiB or more | 250 GiB or more | more | more | 6,000 |

The vector and memory numbers are advice, not hard caps.
At 70% of any of them, `GET /api/storage` and `/api/metrics` recommend the next profile.
A key can get its own rate limit with `rate_limit_per_minute` in its metadata.

The Engine is a single writer: run one Engine per data folder.

## Replication

Two SQLite Engines can keep a workspace in sync.

| Route | What it does |
|---|---|
| `POST /api/sync/enable` | Start recording changes in a workspace |
| `POST /api/sync/peers` | Add a peer: `{"workspace", "url", "api_key", "policy", "max_class"}` (`admin`) |
| `POST /api/sync/run` | Sync now |
| `GET /api/sync/status`, `/changes`, `/conflicts` | State, the change log, and conflicts |
| `POST /api/sync/conflicts/:id/resolve` | Resolve one conflict |

`policy` is `push`, `pull`, `both`, or `none`.
`max_class` is the most sensitive data class that may leave: `public`, `internal`, `confidential` (default), or `restricted`.
The peer's key is stored encrypted with `CONNECTOR_KEY`.
Peers sync every 20 seconds by default.
Assets, connectors, API keys, jobs, and tools are not replicated.

## Move a workspace

A workspace bundle is one file with a whole workspace in it.

| Route | What it does |
|---|---|
| `POST /api/workspaces/:id/bundle` | Write a bundle |
| `POST /api/bundles/import` | Import one |
| `POST /api/bundles/jobs/export`, `POST /api/bundles/jobs/import` | The same as background jobs, for large workspaces |
| `GET /api/bundles/jobs/:id` | Follow a job |
| `POST /api/workspaces/:id/finalize-move` | Remove the workspace from the old Engine after the move |

Bundles are limited to 5 GiB (`OPTIMAL_BUNDLE_MAX_BYTES`).

## Erasure and retention

```bash
mix optimal.compliance dsar <principal id>
mix optimal.compliance erase <principal id> --preview
mix optimal.compliance erase <principal id>
mix optimal.compliance hold place <signal id> --by <actor> --reason "litigation"
mix optimal.compliance hold list
mix optimal.compliance retention sweep --dry-run
```

| Action | Effect |
|---|---|
| `dsar` | Exports what the Engine holds about one person |
| `erase` | Deletes it, and what was derived from it. `--preview` shows what would go; `--force` overrides legal holds. |
| `hold` | Places, lists, or releases a legal hold that stops deletion |
| `retention sweep` | Applies each source's retention rule |
| `POST /api/workspaces/:id/archive` | Archives a workspace; its rows are kept |

An erasure does not reach backups, offsite copies, exported bundles, or replicas that already synced the data.
SQLite does not overwrite freed pages, so deleted text can remain in the database file until it is vacuumed.

## Observability

| Route | What it returns |
|---|---|
| `GET /api/health` | `up`, `degraded`, or `down`, with the check that failed |
| `GET /api/metrics` | JSON counters, latencies, connector state, and size gauges |
| `GET /api/metrics/prometheus` | Prometheus text, such as `optimal_engine_search_latency_ms`, `optimal_engine_memories_total`, `optimal_engine_uptime_seconds` |
| `GET /api/viability` | A report on the workspace as an operating system, with alerts |

The Prometheus route needs a key when keys are required; it is only exempt from rate limits.
`deploy/grafana-dashboard.json` in the repository is a ready dashboard for it.
Logs go to standard output as `[level] message`.

# Optimal Engine quickstart

URL: https://miosa.ai/docs/optimal-engine/quickstart
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/quickstart
Source: src/routes/docs/optimal-engine/quickstart/+page.md
Description: Run Optimal Engine on your own machine, mint an API key, create a workspace, store a source, and search it - from a checkout or with Docker - plus the shortest path on MIOSA.

This guide runs one Engine on your machine, creates a workspace, stores a source, and finds it again.
It takes about ten minutes, most of it the first compile.
To use a managed Engine on MIOSA instead, skip to [On MIOSA](#on-miosa).

You end with:

- an Engine on `http://127.0.0.1:4200`;
- an API key that scopes every request;
- a workspace `default:notes` with one stored source;
- a search result that points back to that source.

## 1. Run the Engine

You need Erlang/OTP 27 or newer, Elixir 1.17 or newer, git, and a C toolchain.
On macOS, also run `brew install snappy`.

```bash
git clone https://github.com/Miosa-osa/OptimalEngine.git
cd OptimalEngine
mix deps.get
```

Mint the first key before the server starts.
The key is printed once, so copy it now.

```bash
mix optimal.auth mint --name "root" --workspace '*'
```

Start the Engine with the HTTP API on and keys required:

```bash
OPTIMAL_API_ENABLED=true OPTIMAL_AUTH_REQUIRED=true mix run --no-halt
```

The first start runs every database migration before the API answers.

You need Docker.
The first image build compiles RocksDB and can take 30 to 60 minutes.

```bash
git clone https://github.com/Miosa-osa/OptimalEngine.git
cd OptimalEngine
docker build -f deploy/Dockerfile.engine \
  --build-arg OPTIMAL_RELEASE_CHANNEL=stable \
  -t optimal-engine:quickstart .
```

Mint the first key in a one-off container that opens the same volume with the API off:

```bash
docker run --rm -v optimal-data:/data -e OPTIMAL_API_ENABLED=false optimal-engine:quickstart \
  /app/bin/optimal eval \
  'OptimalEngine.Auth.ApiKey.mint(%{tenant_id: "default", name: "root", scopes: ["*"], workspace_scope: ["*"]}) |> IO.inspect()'
```

Start the Engine.
`OPTIMAL_ENGINE_API_KEY` is the key you just minted; the container health check uses it.

```bash
docker run -d --name optimal-engine -p 127.0.0.1:4200:4200 \
  -v optimal-data:/data \
  -e OPTIMAL_AUTHORITY_KEY="$(openssl rand -hex 32)" \
  -e CONNECTOR_KEY="$(openssl rand -hex 32)" \
  -e OPTIMAL_ENGINE_API_KEY="<your key>" \
  optimal-engine:quickstart
```

The image turns on the API and requires keys by default.
Everything the Engine stores lives in the `optimal-data` volume, so replacing the container keeps your data.

## 2. Check that it answers

In a second terminal:

```bash
export OPTIMAL_ENGINE_API_KEY="<your key>"
curl -s http://127.0.0.1:4200/api/health -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY"
```

```json
{
  "status": "up",
  "live": true,
  "checks": {
    "store": ":ok",
    "migrations": ":ok",
    "credential_key": ":ok",
    "network_auth": ":ok"
  },
  "degraded": [],
  "warnings": []
}
```

`status` is `up`, `degraded` when there is a warning, or `down` when a check fails.
The real response also carries the release identity.

## 3. Create a workspace

```bash
curl -s -X POST http://127.0.0.1:4200/api/workspaces \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"slug": "notes", "name": "Notes"}'
```

The response is the new workspace.
Its `id` is `default:notes`; use that id everywhere below.

## 4. Store a source

```bash
curl -s -X POST http://127.0.0.1:4200/api/ingest \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace": "default:notes",
    "title": "Supplier renewal call",
    "text": "Renewal call with the supplier moved to the 14th. The contract review is still open."
  }'
```

```json
{
  "ok": true,
  "signal_id": "...",
  "genre": "...",
  "type": "...",
  "entities": [],
  "source_package_id": "..."
}
```

The Engine kept the source, classified it, and proposed claims from it.
A claim becomes a fact once it is reviewed or meets the workspace's promotion rule; see [Concepts](/docs/optimal-engine/concepts/#claims-and-facts).

## 5. Search and ask

```bash
curl -s "http://127.0.0.1:4200/api/search?q=supplier%20renewal&workspace=default:notes&limit=5" \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY"
```

Each result has a `title`, the matching `content`, a `score`, and a `uri` in the `optimal://` scheme that points back to the source.

```bash
curl -s -X POST http://127.0.0.1:4200/api/rag \
  -H "Authorization: Bearer $OPTIMAL_ENGINE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "What is open with the supplier?", "workspace": "default:notes", "format": "markdown"}'
```

`envelope.body` is the context an answer should be written from, and `envelope.sources` lists the sources it used.
The Engine does not write the answer itself; hand the envelope to your model or agent.

Out of the box, search is full-text.
Run [Ollama](https://ollama.com) with `nomic-embed-text`, or point `OPTIMAL_EMBED_URL` at an embeddings endpoint, to add vector search.
See [Install and configure](/docs/optimal-engine/install/#embeddings).

## 6. Use the client CLI

The repository ships a small client CLI, `optimal` (also called `oe`), that needs only `sh`, `curl`, and `awk`.

```bash
apps/cli/install.sh
export OPTIMAL_ENGINE_URL=http://127.0.0.1:4200
optimal doctor
optimal search "supplier renewal" -w default:notes
```

See [CLI, SDKs and MCP](/docs/optimal-engine/cli-sdks-mcp/) for every command and for connecting an agent over MCP.

## On MIOSA

Managed Engines are enabled per organization.
Once yours is enabled:

1. Open **Optimal > Memory** in the console and pick a workspace.
2. Press **Start Memory**. The console shows the size and the hourly price before it creates anything.
3. When Memory is running, search it on the same page, or ask Optimal in a chat to save a note to Memory.

From a terminal, the [MIOSA CLI](/docs/cli/) does the same:

```bash
miosa engine create notes-brain --workspace notes --for workspace --wait
miosa engine connect notes-brain
optimal search "supplier renewal"
```

See [Optimal Engine on MIOSA](/docs/optimal-engine/miosa/) for what is included and how to ask for access.

# Optimal Engine troubleshooting

URL: https://miosa.ai/docs/optimal-engine/troubleshooting
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal-engine/troubleshooting
Source: src/routes/docs/optimal-engine/troubleshooting/+page.md
Description: Fixes for common Optimal Engine problems - nothing listening, health checks, keys refused, empty search, hybrid search unavailable, busy store, failed migrations, Docker health, and errors from a managed Engine on MIOSA.

Each entry starts with what you see, then the fix.

## Start-up

### "Optimal Engine needs Erlang/OTP 27 or later"

The Engine uses the JSON module that ships with OTP 27.
Install OTP 27 or newer; avoid 28.0 to 28.2.

### The Engine starts but nothing listens on port 4200

The HTTP API is off unless `OPTIMAL_API_ENABLED=true`.
Set it and start again.
`mix optimal.api` alone prints a listening line without turning the API on, so set the variable for it too.

### "OPTIMAL_AUTH_REQUIRED must be true or false"

A setting has a value the Engine does not accept, and the boot stops.
The message names the variable; fix its value.
The same applies to `OPTIMAL_EMBED_URL`, `OPTIMAL_SIZE_PROFILE`, `OPTIMAL_ENGINE_SCOPE`, and the other settings in [Install and configure](/docs/optimal-engine/install/#settings).

### "migration ... failed and was rolled back"

An upgrade's migration failed.
The Engine will not open the store until it is fixed.
Restore the backup you took before the upgrade, then start the previous version; see [Operations](/docs/optimal-engine/operations/#upgrades).

### The Docker container stays "unhealthy"

The health check calls `/api/health` with `OPTIMAL_ENGINE_API_KEY`, and keys are required in the image.
Set `OPTIMAL_ENGINE_API_KEY` on the container to a valid key.

## Health

`GET /api/health` reports `status` and the checks behind it.

| Warning or error | Fix |
|---|---|
| `store_unreachable` | The database file cannot be opened. Check `OPTIMAL_ENGINE_DB`, the disk, and file permissions. |
| `migrations_pending` | Restart the Engine so it applies them, or run `mix optimal.migrate`. |
| `connector_key_missing` | You set up a connector or a replication peer without `CONNECTOR_KEY`. Set it to 64 hex characters. |
| `auth_open_on_network` | The Engine is bound beyond loopback with keys off. Set `OPTIMAL_AUTH_REQUIRED=true`. |
| `embedder_unreachable`, `embedder_unauthorized`, `embedder_dimension_mismatch` | Shown with `?full=true`. Check `OLLAMA_HOST` or `OPTIMAL_EMBED_URL`, its key, and `OPTIMAL_EMBED_DIMENSIONS`. |

## Requests

### 401 `missing_api_key` on every call, including `/api/health`

Keys are required.
Send `Authorization: Bearer <key>`.
Mint the first key with `mix optimal.auth mint`, or set `OPTIMAL_BOOTSTRAP_KEY`.

### 403 `workspace_scope_denied`

The key does not cover that workspace.
Check its workspaces with `GET /api/auth/whoami`, and mint a key that includes the workspace.

### 400 `workspace_required`

The key is limited to named workspaces and the request named none.
Pass `workspace`, or `-w` in the CLI.

### Search returns nothing for something you just stored

- Use the same full workspace id, such as `default:notes`, in every call.
  The Engine does not look up a bare slug such as `notes`; it treats it as a different workspace id.
- A context package from `assemble` holds reviewed facts only; a new source shows up there after its claims are promoted.
  Use `search` to see sources right away.

### 503 `hybrid_unavailable`

`mode=hybrid` needs an embedding model, and none answered.
Use `mode=auto`, which falls back to full-text, or set up embeddings; see [Install and configure](/docs/optimal-engine/install/#embeddings).

### 503 `busy` with `Retry-After: 1`

The store was busy, often right after boot or during a long write.
Retry after the delay.

### 429 `rate_limited`

The key used its budget for the minute.
Wait `retry_after_ms`, or raise the size profile or the key's `rate_limit_per_minute`; see [Operations](/docs/optimal-engine/operations/#sizing).

### 426 `client_incompatible`

The `optimal` CLI or MCP server is of a different major version than the Engine.
Update the client from the same release as the Engine.

## On MIOSA

### "Memory could not be started"

Your organization does not have managed Engines enabled, or your role cannot create databases.
See [Availability](/docs/optimal-engine/miosa/#availability).

### 422 `ENGINE_NOT_AVAILABLE`

Managed Engines are not enabled for your organization.
Contact support to have them turned on.

### 409 `ENGINE_NOT_RUNNING`

The Engine is stopped or still starting.
Start it from **Databases**, or wait about a minute after creating it.

### 404 `NOT_FOUND` from the engine-api proxy

The route is not one a client key may call, or the workspace has no Engine.
See the allowed routes in [Optimal Engine on MIOSA](/docs/optimal-engine/miosa/#call-the-engine-api).
Key, backup, sync, and maintenance routes are managed through MIOSA instead.

### A client key stopped working

Client keys expire, after 24 hours by default.
Run `miosa engine connect <engine>` again, and restart the MCP server, which reads its key once at start.

# Optimal API

URL: https://miosa.ai/docs/optimal/api
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/api
Source: src/routes/docs/optimal/api/+page.md
Description: HTTP reference for Optimal - mint an Optimal token, create chats, send messages, stream replies, bind a machine, upload attachments, decide approvals, and read a chat's cost.

The Optimal API is the same API the console uses.
Everything a chat in the console does starts from these endpoints, and chats you create here show up in the console's **History**.

| | |
|---|---|
| Base URL | `https://optimal.miosa.ai/api/v1` |
| Auth | `Authorization: Bearer ` |
| Body | JSON with `Content-Type: application/json`, except attachment uploads |
| Errors | `{"error": "<code>", "details": "<message>"}` |

## Authentication

Optimal does not take your API key directly.
Your API key mints a short-lived **Optimal token** on the MIOSA API, and every Optimal call uses that token.

The API key needs the **Chat with Optimal and start runs** permission (`osa:write`).
To approve or reject Optimal's changes with the token, the key also needs **Approve or reject Optimal's changes** (`osa:approve`).
A key bound to one workspace can mint a token for that workspace only.

### Mint a workspace token

`POST https://api.miosa.ai/api/v1/optimal/workspace-token`

```bash
curl -s https://api.miosa.ai/api/v1/optimal/workspace-token \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"workspace_id": "your_workspace_id"}'
```

```json
{
  "token": "eyJhbGciOi...",
  "expires_at": 1792771200,
  "can_decide_approvals": false,
  "scope": {
    "user_id": "...",
    "tenant_id": "...",
    "workspace_id": "your_workspace_id",
    "workspace_role": "admin"
  }
}
```

- The token lasts 10 minutes; `expires_at` is a Unix time in seconds.
  Mint a new one when a call answers `401`.
- Chats belong to the key's user and to the workspace in the token.

| Status | Code | When |
|---|---|---|
| 401 | `UNAUTHORIZED` | The API key is missing or revoked |
| 403 | `FORBIDDEN` | The key does not have `osa:write` |
| 403 | `WORKSPACE_FORBIDDEN` | The key's user is not a member of the workspace |
| 403 | `API_KEY_WORKSPACE_BOUND` | The key is bound to a different workspace |
| 403 | `API_KEY_NOT_ELIGIBLE` | The key is bound to a project or an end user |
| 422 | `WORKSPACE_REQUIRED` | `workspace_id` is missing |

### Mint an organization token

`POST https://api.miosa.ai/api/v1/optimal/org-token` takes no body.
It mints a token for an **All workspaces** chat, which reads every workspace the user belongs to and asks which one to use before changing anything.
A key bound to one workspace cannot mint it.

## Chats

A chat is called a session in the API.

### Create a chat

`POST /sessions`

```bash
curl -s https://optimal.miosa.ai/api/v1/sessions \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"resume": false}'
```

```json
{
  "id": "your_chat_id",
  "status": "created",
  "machine": null,
  "workspace": { "id": "your_workspace_id", "rule": "This chat belongs to the workspace it was started in and never moves; its machines, memory and spend are that workspace's." },
  "pending_workspace": null,
  "turn": { "state": "idle", "turn_id": null, "started_at": null, "last_event_seq": 0 }
}
```

| Field | Type | Description |
|---|---|---|
| `resume` | boolean | Send `false` to always start a fresh chat |
| `client_key` | string | Your own key for this chat; creating again with the same key resumes it (`status: "resumed"`) |
| `model` | string | Optional; the only value is `optimal` |

### List chats

`GET /sessions`

| Query | Description |
|---|---|
| `page`, `per_page` | Pagination; `per_page` is 20 by default, at most 100 |
| `view` | `mine` (default), `team` for shared chats, or `members` for owners and admins |

```json
{
  "sessions": [
    { "id": "your_chat_id", "title": "Landing page", "message_count": 6, "created_at": "2026-10-23T14:02:11Z", "visibility": "personal" }
  ],
  "count": 1,
  "page": 1,
  "per_page": 20
}
```

### Rename or share a chat

`PATCH /sessions/{id}` with any of:

| Field | Values |
|---|---|
| `title` | Text |
| `mode` | `ask`, `build`, `investigate` |
| `visibility` | `personal`, `team` |

### Delete a chat

`DELETE /sessions/{id}` deletes the chat and its messages for good, and answers `{"status": "deleted", "session_id": "..."}`.
Machines the chat used are not touched.

## Messages

### Send a message

`POST /sessions/{id}/message`

```bash
curl -s https://optimal.miosa.ai/api/v1/sessions/$CHAT/message \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"message": "Why did my latest deployment fail?", "mode": "investigate", "client_message_id": "msg-001"}'
```

The call returns at once with `202`; the reply arrives on the [stream](#streaming).

```json
{
  "status": "processing",
  "session_id": "your_chat_id",
  "turn_id": "msg-001",
  "client_message_id": "msg-001",
  "queued": false
}
```

| Field | Type | Description |
|---|---|---|
| `message` | string | Required. The text to send |
| `mode` | string | `ask`, `build`, or `investigate` |
| `client_message_id` | string | 1 to 128 characters of letters, digits, `_`, `.`, `:`, or `-`. Sending the same id again answers `200` with `status: "duplicate"` instead of a second turn |
| `machine` | object | `{"resource_type": "sandbox" \| "computer", "resource_id": "..."}`: run this message on that machine |
| `confirm_switch` | boolean | `true` to move a chat that is already working on another machine |
| `attachments` | array | Attachment ids from [Attachments](#attachments) |

A message sent while Optimal is working waits behind the current turn, and `queued` is `true`.
`DELETE /sessions/{id}/queued/{client_message_id}` removes it until it starts; after that the call answers `409 not_queued`.

### Read the transcript

`GET /sessions/{id}/messages`

```json
{
  "messages": [
    { "role": "user", "content": "Why did my latest deployment fail?", "timestamp": "2026-10-23T14:02:11Z" },
    { "role": "assistant", "content": "The build failed at npm install...", "timestamp": "2026-10-23T14:02:40Z" }
  ],
  "count": 2,
  "queued": [],
  "owner": { "id": "...", "label": "Ada" }
}
```

### Stop a reply

`POST /sessions/{id}/cancel` answers `{"status": "cancel_requested"}`.
When nothing is running it answers `404 not_running`.

## Streaming

`GET /sessions/{id}/stream` is a Server-Sent Events stream.

```bash
curl -N https://optimal.miosa.ai/api/v1/sessions/$CHAT/stream \
  -H "Authorization: Bearer $TOKEN"
```

- A browser `EventSource` cannot set headers, so this endpoint also takes the token as `?token=`.
  No other endpoint accepts a token in the URL.
- Every event has a numbered `id:`.
  Reconnect with the `Last-Event-ID` header, or `?last_event_id=`, to replay what you missed.
- A new reader with no id gets the turn in flight from its start; finished turns come from `GET /sessions/{id}/messages`.
- If the events you missed are gone, the stream sends `replay_gap`; read the transcript, then keep streaming.

The main events:

| Event | Data | Meaning |
|---|---|---|
| `connected` | `session_id` | The stream is open |
| `turn_start` | `turn_id` | Optimal started on a message |
| `streaming_token` | `text`, `message_id` | The next piece of the reply |
| `tool_call` | `name`, `phase` (`start` or `end`) | Optimal is using a tool |
| `permission_required` | the step that waits | A step needs approval; see [Approvals](#approvals) |
| `agent_response` | `response` | The finished reply |
| `turn_billed` | `turn_credits`, `session_credits`, `balance` | What the turn cost, once the ledger settles |
| `replay_gap` | `session_id`, `last_seq` | Events you asked to replay are gone |

Ignore events you do not use; new events can be added.

## Machines

A chat can work on one sandbox or computer in your workspace at a time.

`POST /sessions/{id}/machine`

```json
{ "resource_type": "sandbox", "resource_id": "your_sandbox_id" }
```

Answers `{"session_id": "...", "machine": {"resource_type": "sandbox", "resource_id": "..."}}`.
`DELETE /sessions/{id}/machine` unbinds it; the machine keeps running.

| Status | Code | When |
|---|---|---|
| 400 | `invalid_machine` | `resource_type` is not `sandbox` or `computer`, or `resource_id` is missing |
| 404 | `machine_not_found` | The machine is not in this workspace |
| 409 | `machine_unavailable` | The machine is not running or cannot be reached |
| 409 | `machine_switch_requires_confirmation` | The chat is working on another machine; send `confirm_switch: true` |

## Attachments

`POST /sessions/{id}/attachments?name={file_name}` takes the raw file bytes as the body.

```bash
curl -s "https://optimal.miosa.ai/api/v1/sessions/$CHAT/attachments?name=error.log" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/octet-stream" \
  --data-binary @error.log
```

```json
{ "id": "att_...", "name": "error.log", "mime": "text/plain", "bytes": 2048, "path": "/workspace/uploads/error.log", "vision": false }
```

Pass the `id` in the next message's `attachments`.
Files are up to 10 MB each and 25 MB per chat.
A file that is neither an image nor a document needs a machine bound to the chat, or the call answers `409 no_machine`.

## Approvals

`GET /approvals` lists approvals; filter with `session_id` and `status` (`pending`, `approved`, `rejected`).

```json
{ "approvals": [ { "id": "...", "status": "pending", "session_id": "your_chat_id", "title": "Delete sandbox api-old" } ], "count": 1 }
```

- `POST /approvals/{id}/approve` approves; `POST /approvals/{id}/reject` declines.
  Both take an optional `reason`.
- A token whose `can_decide_approvals` is `false` gets `403 approval_scope_required`.
- Deciding twice answers `409 already_decided`.

See [Approvals](/docs/optimal/approvals/).

## Models

`GET /models` returns one model, `optimal`, with its live price:

```json
{
  "models": [
    {
      "id": "optimal",
      "name": "Optimal",
      "provider": "MIOSA",
      "context_window": 1048576,
      "default": true,
      "credits_per_1m": { "input": 150, "output": 600 },
      "pricing": {
        "unit": "wallet credits (1 credit = 1 cent)",
        "input_credits_per_1m": 150,
        "output_credits_per_1m": 600
      }
    }
  ],
  "current": "optimal",
  "default": "optimal",
  "currency": "wallet credits (1 credit = 1 cent)"
}
```

Any other `model` value answers `400 MODEL_NOT_ALLOWED`.

## A chat's cost

`GET https://api.miosa.ai/api/v1/credits/session/{chat_id}` is on the MIOSA API and takes your API key.

```json
{
  "session_id": "your_chat_id",
  "model_credits": 12,
  "machine_credits": 7,
  "total_credits": 19,
  "attributed": true,
  "settled": true,
  "as_of": "2026-10-23T14:10:00Z"
}
```

## Errors

| Status | Code | Meaning |
|---|---|---|
| 400 | `missing or empty message` | `message` is empty |
| 401 | `MISSING_TOKEN`, or an expired token | Mint a new Optimal token |
| 402 | `OPTIMAL_CREDITS_REQUIRED` | No credits left; add credits or upgrade |
| 403 | `ownership_denied` | The machine is not in your organization |
| 404 | `session_not_found` | The chat does not exist, or is not yours |
| 415 | `unsupported_media_type` | A JSON body without `Content-Type: application/json` |
| 429 | `rate_limited` | Too many requests; wait for `Retry-After` |
| 429 | `session_ceiling` | Too many chats running at once for your organization |

A chat in another organization or workspace answers `404`, the same as one that does not exist.

The Optimal token reaches chats, history, artifacts, investigations, approvals, cost, and settings.
It cannot run tools directly or reach MIOSA's own servers.
See [Isolation and permissions](/docs/optimal/isolation/).

# Approvals

URL: https://miosa.ai/docs/optimal/approvals
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/approvals
Source: src/routes/docs/optimal/approvals/+page.md
Description: Decide which Optimal steps wait for you, approve or decline them in the chat, allow a step for the rest of a chat, and let an API key approve.

Optimal asks before it acts.
When a step needs your decision, the chat pauses and an approval card appears above the composer.

## Approve or decline

An approval card names the step Optimal wants to take.

- **Approve** lets that one step run.
- **Decline** refuses it, and Optimal continues another way or tells you what it could not do.
- **Allow for this chat** approves it and lets the same kind of step run without asking for the rest of the chat.
  It shows only for steps that can be remembered.

When several cards are waiting, the newest shows first with "N more waiting".

## Choose what Optimal asks before

In **Preferences**, under **Approvals**, **Ask before** sets which steps wait for you in the workspace:

| Setting | Steps that wait |
|---|---|
| Every step | Every step that uses a tool |
| Changes only | Steps that change something |
| Deletions only | Steps that delete something |

The default is **Changes only**.
The setting is yours: it applies to your chats in this workspace, on every device.

## Auto-approve

The **Auto-approve** switch sits in the chat header of an Optimal chat.
When it is on, Optimal runs every tool it asks for in this workspace without stopping.
Turn it off to go back to the **Ask before** setting.

On an empty chat, the same switch sits under the composer.
Auto-approve is offered for the Optimal brain only.

## Allowed in this chat

Every step you allowed with **Allow for this chat** is listed under **...** > **Allowed in this chat (N)** in the chat header.
**Remove** puts a step back to asking.
When nothing is allowed, the list reads "Nothing is allowed without asking in this chat."

## Every pending approval

**Approvals** in the Optimal sidebar lists approvals across your chats in the workspace.
Each row says which chat it came from, and you can search the list.
A pending approval expires when the turn that asked for it ends.

## Signing in to a site

When Optimal needs to sign in to a site in its browser, it shows a secure sign-in card instead of asking in the chat.
What you type goes straight to the sign-in page and is not saved in the chat.
Tick **Save for next time** to keep the sign-in; saved sign-ins are listed in **Preferences** under **Sign-ins**, with a masked name only.
**Not now** skips it.

## Approvals over the API

An Optimal token minted from an API key can approve or reject only if the key has the **Approve or reject Optimal's changes** permission (`osa:approve`).
The token's `can_decide_approvals` field says whether it can.
Without it, the decision routes answer `403 approval_scope_required`, so a script cannot approve its own changes unless you allowed that.

```bash
# Pending approvals in one chat
curl -s "https://optimal.miosa.ai/api/v1/approvals?session_id=$CHAT&status=pending" \
  -H "Authorization: Bearer $TOKEN"

# Approve one
curl -s -X POST https://optimal.miosa.ai/api/v1/approvals/$APPROVAL/approve \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"reason": "Looks right"}'
```

`/reject` declines.
Deciding twice answers `409 already_decided`.
See the [Optimal API](/docs/optimal/api/#approvals).

Auto-approve and **Ask before** apply to your Optimal chats in the workspace, on every device.
Platform policy still applies on top.

# Brains and agents

URL: https://miosa.ai/docs/optimal/brains
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/brains
Source: src/routes/docs/optimal/brains/+page.md
Description: Choose who answers an Optimal chat - the built-in Optimal model, a coding harness on your own account, or a saved agent you built in Agent Studio.

The brain is who answers a chat.
Pick it in the composer's brain picker (tooltip "Choose who answers") before the first message.

## The three kinds of brain

| Brain | Billed to | Where it runs | Best for |
|---|---|---|---|
| **Optimal** | Wallet credits | MIOSA, working on your machines through scoped tools | Questions about your workspace, building, investigating |
| **A harness** | Your own model account | On the sandbox or computer you pick | Coding with Claude Code, Codex, OSA, and others |
| **A saved agent** | Your own model account | On the sandbox or computer you pick | An agent with your own instructions, tools, and permissions |

## Optimal

Optimal is the model built into MIOSA.
The picker shows it as "Built into MIOSA" and "Uses your wallet credits, about 4 credits per message".

- It is one model, with a 1M-token context.
- You cannot pick a different model for it, and it does not use your own model keys.
- It is the only brain that offers Investigate mode.

On the free plan with no credits left, Optimal is disabled in the picker with "Add credits to use Optimal".

## Harnesses

A harness is a coding agent that runs on a machine on your own account.
MIOSA credits never pay for its model.
The picker lists the harnesses under **Your agents**:

- Claude Code, Codex, and OSA;
- OpenCode, pi, Prime Agent, Kimi Code, Mistral Vibe, and Hermes, when your organization can connect them.

Each row shows its connection state: "Connected" with the account, "Not connected", or "Needs signing in again".
**Connect** or **Reconnect** opens the sign-in for that harness, then returns you to Optimal.
See [Harnesses and auth](/docs/agents/harnesses/) for what each harness accepts.

A harness always asks where to work, in any mode, because each message is a run on a machine.
The cost strip says the work is billed to your own plan.

## Saved agents

A saved agent is an agent you built in Agent Studio, with its own instructions, harness, model, tools, and permissions.
Saved agents appear under **Your agents** next to the harness they use.
An archived agent is not listed.

To build one, choose **Build an agent** at the bottom of the brain picker, or open [Agent Studio](/docs/agents/agent-studio/).
From the CLI:

```bash
miosa agent new reviewer --harness claude-code --instructions-file review.md
miosa agent list
```

## Switching brains

The brain is fixed after the first message.
The picker's tooltip then reads "This chat keeps its brain. Start a new chat to change it."
Picking another brain in a started chat starts a new chat.

Harnesses and saved agents run on your own model account.
Optimal's model is MIOSA's, and is paid only in wallet credits.

# Chats and modes

URL: https://miosa.ai/docs/optimal/chats
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/chats
Source: src/routes/docs/optimal/chats/+page.md
Description: How an Optimal chat works - the composer, Ask, Build and Investigate, attachments, queued messages, the context meter, and renaming or deleting a chat.

A chat is one conversation with one brain, in one workspace.
Open **Optimal** in the sidebar to reopen your most recent chat in the current workspace, or press **New** to start a fresh one.

## Pick a workspace first

Optimal works in one workspace at a time.
With a single workspace selected, the chat can read and change resources in that workspace only.

If **All workspaces** is selected, the chat reads every workspace you belong to.
It asks which workspace to use before it changes anything.

## The composer

The empty chat shows a headline for the current mode, three starter suggestions, and the composer.
From left to right, the composer toolbar has:

| Control | What it does |
|---|---|
| **+** | Adds files or MIOSA resources to the chat as context |
| Mode menu | Switches between Ask, Build, and Investigate |
| Brain picker | Chooses who answers; see [Brains and agents](/docs/optimal/brains/) |
| Machine menu | Chooses where Optimal works; shown in Build mode or once a machine is involved |
| **Send message** | Sends; while Optimal is working it becomes **Queue message** |
| **Stop** | Cancels the running reply |

Under the input, the cost strip shows what the chat has cost so far.
See [Pricing and usage](/docs/optimal/pricing/).

## Modes

| Mode | Use it to | Starter suggestions |
|---|---|---|
| Ask | Get answers from live workspace context | "What needs my attention in this workspace?", "Summarize what changed in the last day" |
| Build | Build or change something on a sandbox or computer | "Build a landing page and publish it", "Build a small API with a database" |
| Investigate | Trace evidence before reaching a conclusion | "Why did my latest deployment fail?", "Trace the most recent error in my logs" |

You can change the mode between messages.
After an answer in Ask mode, **Switch to Build and run this** turns the answer into work on a machine.

Investigate always runs on the Optimal brain.
With a harness or saved agent as the brain, Investigate is not offered; start a new chat to use it.

## Add context

Press **+** to open **Add context**.
You can:

- attach files: images, documents, or any file, up to 10 MB each and 25 MB per chat;
- drop or paste files straight into the composer;
- point Optimal at MIOSA resources in your workspace.

Optimal takes three kinds of file:

| Kind | Examples | What happens |
|---|---|---|
| Image | PNG, JPEG, WebP, GIF | The model sees it |
| Document | PDF, Word, Excel, CSV, Markdown, JSON, code | Its text is read into the message |
| Any other file | Archives, binaries | It is written to the chat's machine, under `/workspace/uploads` |

Any other file needs a machine bound to the chat; pick a sandbox or computer, then send again.
When the chat has a machine, images and documents are copied to it too.

## Send while Optimal works

You can keep typing while Optimal works.
**Queue message** sends your message right after the current reply finishes.
A queued message can be removed until it starts.

## Stop

**Stop** cancels the reply in progress.
The chat shows "Stopped", and what Optimal finished before you stopped it stays in the chat.

## Context and compaction

Every chat has a 1M-token context.
The context meter in the chat header shows how much is used, for example "312K of 1M context".
It turns amber at 70% and red at 90%.

When the context fills, Optimal folds the older part of the chat into a short summary on its own.
The meter shows "Compacting context..." while it does.
Nothing is needed from you.

## Rename, share, delete

The **...** menu in the chat header (tooltip "Chat options") has:

- **Rename**: gives the chat a new title.
- **Allowed in this chat**: lists the steps you allowed without asking, with **Remove** on each; see [Approvals](/docs/optimal/approvals/).
- **Delete**: deletes the chat and its messages for good.
  Machines the chat used are not touched.

To share a chat with your team, use **Share with team** from its menu in **My chats**.
See [Team chats and sharing](/docs/optimal/team-chats/).

## Ask Optimal from any page

On project, product, deployment, agent, workflow, computer, sandbox, database, and storage pages, the sidebar shows **Ask Optimal**.
It opens Optimal next to the page, with that page as context.
The shortcut is <kbd>Alt</kbd> + <kbd>Shift</kbd> + <kbd>O</kbd>.

## Find a chat again

**History** in the Optimal sidebar lists every chat in the workspace, with search and **Load older chats**.
Recent chats also sit in the sidebar under **Mine** and **Team**.
How long chats stay is set in **Preferences**: 30 days, 90 days, or 1 year.
See [Tasks, artifacts and history](/docs/optimal/workspace/).

The brain is fixed after the first message.
Picking a different brain in a started chat starts a new chat.

# Isolation and permissions

URL: https://miosa.ai/docs/optimal/isolation
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/isolation
Source: src/routes/docs/optimal/isolation/+page.md
Description: Optimal acts only inside your organization and workspace, with your permissions, and never on MIOSA's own keys.

Optimal acts only inside your organization and workspace, with your permissions.
It never reaches anything you could not reach yourself.

## Scoped per chat

Every key Optimal holds is scoped to one chat:

- a machine key bound to one sandbox or computer; or
- a workspace key bound to your organization, workspace, and user.

Both are minted per chat from the chat's saved scope, never from a message or a tool argument.
They are short-lived, and are never logged or saved in a tool result.

## Every call re-checks the scope

Each tool call re-derives your organization, workspace, and user from the chat.
An id in a tool argument is ignored.
A foreign organization, a sibling workspace, and an unknown id all get the same answer: not found, or no access.

## Nothing runs on MIOSA's host

For a hosted chat, no shell or file tool runs on the Optimal host.
Those tools run only on the machine the chat is bound to.
Tool output is cleaned before the model or the stream sees it.

## Dispatched agents get none of Optimal's authority

When Optimal dispatches a harness run, the run request carries no key, token, or scope.
The harness runs on your own account, and Optimal's own reasoning bills wallet credits.

# Build on your machines

URL: https://miosa.ai/docs/optimal/machines
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/machines
Source: src/routes/docs/optimal/machines/+page.md
Description: Choose the sandbox or computer Optimal works on, use the side panel to watch and steer it, publish a preview, and take over from the agent at any time.

Optimal does its building on a machine: a sandbox or a computer in your workspace.
You choose which one, and you can watch, steer, or take over at any time.

## Choose a machine

The machine menu sits in the composer toolbar.
It shows in Build mode, or once the chat has a machine.
Its label is **Auto** until you pick one, then the machine's name.

When you send a Build message and the chat has no machine, the menu opens on its own.
You can:

- pick **New sandbox**, with a size and its hourly price;
- pick **New computer**, with its hourly price;
- pick a machine you already have, under **Other machines in this workspace**.

A new sandbox has an idle timeout of 30 minutes.

A harness or saved agent always asks where to work, in any mode, because each message is a run on a machine.

## Machines in this chat

Under **This chat** the menu lists the chat's machines.
For each machine you can **Open** it, choose **Run next message here**, pause or resume it, stop it, or delete it.
**Add a sandbox** and **Add a computer** add another.

At the bottom of the menu:

| Action | What it does |
|---|---|
| **Pause all** | Pauses every machine in the chat |
| **Remove all** | Deletes every machine of the chat for good, after a confirm; their files are lost unless you took snapshots |
| **See all** | Opens the full machine list |
| **Show the preview** | Opens the Preview tab |
| **Detach from this chat** | Unbinds the machine; it keeps running |

If Optimal wants to move the chat to a different machine, it asks "Move this chat to ...?" with **Keep current** and **Move it**.

## The side panel

When work starts, the side panel opens on the right and follows the chat's machine.
Toggle it with **Open side panel** and **Close side panel**, and drag its edge to resize it.

| Tab | Shows |
|---|---|
| Preview | Your app, live from the machine |
| Browser | The live browser Optimal is using, from a sandbox |
| Desktop | The computer's live desktop |
| Machine | The sandbox or computer itself: its state, size, cost, and controls |
| Progress | What the agent is doing now and what it has finished |
| Terminal | A shell on the machine |
| Files | Browse and edit what is on the machine |
| Code | Every file changed in this chat, with its changes |
| Artifacts | Everything Optimal has produced for you |
| Deployments | Your sites and apps, and whether they are live |
| Logs | What the machine and its apps print |

A tab that does not apply yet shows what to do, for example "No computer in this chat" with **Add a computer**.

## Preview and publish

When Optimal serves an app, a preview card appears in the chat.
**Open preview** opens it; **Publish** puts it on a public URL.

The publish sheet asks for:

- **Update this site** or **New site**;
- the site name;
- the folder to publish, `/workspace` by default.

**Publish** creates the site and **Publish update** updates it.
The machine has to be running to publish.
The sheet also links to **Manage**, the custom domain, and recent versions.

## Stop, take over, hand back

- **Stop** cancels the running reply.
- **Take over**, on the Desktop and Browser tabs, pauses the agent and gives you the controls.
  The chat shows "You're in control".
- **Hand back** returns control, and the agent picks up from the machine's current state.

While you are in control, the agent cannot click or type.
If the agent asked you to take over, for example to finish a sign-in, it continues from where you leave the machine.

Clicking the desktop while you are only watching asks first.
Choose **Keep watching** to stay hands-off.

## When the machine is gone

If the chat's machine is deleted, the chat says "This chat's machine was deleted. Pick another, or let Optimal choose."
Pick a machine in the machine menu and send again.

# Pricing and usage

URL: https://miosa.ai/docs/optimal/pricing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/pricing
Source: src/routes/docs/optimal/pricing/+page.md
Description: What an Optimal chat costs, how the cost strip and the Usage page report it, what happens when credits run out, and how harness brains are billed.

An Optimal chat has two costs: the model and the machines it uses.
Both are paid from wallet credits, where 1 credit is 1 cent.

## The Optimal model

| | Price |
|---|---|
| Input | $1.50 per 1M tokens |
| Output | $6.00 per 1M tokens |
| A typical message | About 4 credits |

Billing is in whole credits.
The part of a credit left over from one call carries to the next, so small calls are not each rounded up.

Every chat has the full 1M-token context, with automatic compaction when it fills.
See [Chats and modes](/docs/optimal/chats/#context-and-compaction).

The live price is also returned by the API in `GET /models`, under `pricing`.
See the [Optimal API](/docs/optimal/api/#models).

## Machines

A sandbox or computer that Optimal creates or uses bills at its normal size price, while it runs.
A new sandbox that Optimal creates has a 30-minute idle timeout.
See [Pricing](/docs/pricing/) for machine rates.

## Harnesses and saved agents

A harness or saved agent bills its model to your own account, never to MIOSA credits.
The cost strip says so, for example "Billed to your Claude plan".
The machine it runs on still bills in credits.

## The cost strip

The cost strip sits under the composer and updates while Optimal works.
For an Optimal chat it reads, for example:

```text
12 credits model · 7 credits machines · 19 credits so far · 4,180 left · Add credits
```

| Part | Meaning |
|---|---|
| model | Model calls settled for this chat |
| machines | Machines this chat ran, settled for this chat |
| so far | The two together |
| left | Your wallet balance, in credits |

A running machine settles every few minutes, so the machine figure catches up shortly after the work.
The (i) tooltip explains each figure.

## The Usage page

**Usage** in the Optimal sidebar shows Optimal's spend in the workspace:

- **Total cost**, **Tokens**, **Input**, and **Output**;
- your credit balance;
- **Model activity**: requests and cost for Optimal.

## When credits run out

Optimal needs a positive credit balance.
With no credits left, it does not start a chat or answer a message.
On the free plan, the chat shows "Optimal runs on credits" with **Upgrade** and **Add credits**.
Over the API, the call answers `402` with the code `OPTIMAL_CREDITS_REQUIRED`.

Add credits from **Billing**, or upgrade your plan, then send again.

`GET https://api.miosa.ai/api/v1/credits/session/{chat_id}` returns `model_credits`, `machine_credits`, and `total_credits` for one chat, read from the ledger.
`attributed` is `false` when no machine has been tagged with the chat yet, so the total is the model only.

This walkthrough takes about five minutes.
You ask Optimal a question, have it build a page on a sandbox, and then send the same kind of message from your own code.

## Before you start

- A MIOSA account with a workspace.
- Wallet credits, or a paid plan.
  On the free plan with no credits left, the Optimal brain is disabled until you add credits.

## 1. Ask a question

1. Open **Optimal** in the console sidebar.
2. Pick a single workspace in the workspace switcher.
3. Leave the mode on **Ask** and choose the starter "What needs my attention in this workspace?", or type your own question.
4. Press **Send message**.

Optimal reads your live workspace and answers in the chat.
Ask mode never touches a machine.

## 2. Build something

1. Open the mode menu in the composer and pick **Build**.
2. Type "Build a landing page and publish it", then send.
3. Optimal asks where to build.
   In the machine menu, pick **New sandbox**, or pick a machine you already have.
4. The side panel opens.
   Watch **Progress** for the steps, and open **Preview** when the page is served.

Steps that change your workspace wait for your approval.
Press **Approve** on the card above the composer, or **Allow for this chat** to stop being asked for that kind of step in this chat.

When the page looks right, press **Publish** on the preview card to put it on a public URL.
See [Build on your machines](/docs/optimal/machines/).

## 3. Send a message from code

Optimal has an HTTP API at `https://optimal.miosa.ai/api/v1`.
It takes a short-lived Optimal token, which your API key mints.

Create an API key with the **Chat with Optimal and start runs** permission (`osa:write`), then:

```bash
export MIOSA_API_KEY=msk_your_key
export WORKSPACE=your_workspace_id

# 1. Mint a 10-minute Optimal token for one workspace.
TOKEN=$(curl -s https://api.miosa.ai/api/v1/optimal/workspace-token \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"workspace_id\": \"$WORKSPACE\"}" | jq -r .token)

# 2. Start a chat.
CHAT=$(curl -s https://optimal.miosa.ai/api/v1/sessions \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"resume": false}' | jq -r .id)

# 3. Open the stream in the background, so you see the turn from its start.
curl -sN "https://optimal.miosa.ai/api/v1/sessions/$CHAT/stream" \
  -H "Authorization: Bearer $TOKEN" &

# 4. Send a message. This call returns at once with 202; the reply arrives on the stream.
curl -s https://optimal.miosa.ai/api/v1/sessions/$CHAT/message \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"message": "Summarize what changed in the last day", "mode": "ask"}'
```

The stream sends `streaming_token` events while the reply is written and an `agent_response` event with the full reply.
`GET /sessions/$CHAT/messages` returns the finished transcript at any time.
The chat also appears in **History** in the console.
See the [Optimal API](/docs/optimal/api/) for every endpoint.

Mint a new Optimal token when a call answers `401`.
The chat keeps going; only the token is new.

# Team chats and sharing

URL: https://miosa.ai/docs/optimal/team-chats
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/team-chats
Source: src/routes/docs/optimal/team-chats/+page.md
Description: Optimal chats are personal until you share them with your workspace. Owners and admins can read and join members' chats, and every view is recorded.

A new Optimal chat is personal.
You can share it with everyone in its workspace, and turn it back into a personal chat at any time.

## Share a chat

From a chat's **...** menu in **My chats**:

- **Share with team** opens the chat to everyone in its workspace.
- **Make personal** makes it yours alone again.

## The chat lists

The sidebar's recent chats have tabs, and each opens a full list:

| List | What it shows |
|---|---|
| **My chats** | Your chats with Optimal. A personal chat is yours; a shared one is open to everyone in its workspace. |
| **Team chats** | Chats shared with everyone in the workspace. Anyone can read one and add a message; each message shows who wrote it. |
| **Team members** | Members' personal chats, by person. Shown to organization owners and admins only. |

Rows are marked when a chat is shared, when it is working, when it "Needs you", or when it is "Read only" for you.

## Writing in a shared chat

In a team chat, each message shows who wrote it.
A member who is not the chat's creator sends words only.
The chat's machine, brain, and files stay as its creator set them.

A workspace viewer can read team chats but not post in them.

## Owners and admins

Organization owners and admins can open **Team members** to read members' personal chats, and **Join** one to carry on in the same chat.
Reading and joining are both recorded, and the chat's creator is told when someone joins.

Each person can see who has opened their chats under "Who has opened my chats".
Owners and admins see their own record under "Recorded views of members' chats".

**Preferences** says it plainly: "Your chats are personal until you share them with the team from a chat's menu. Organization owners and admins can view and join your chats."

# Optimal troubleshooting

URL: https://miosa.ai/docs/optimal/troubleshooting
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/troubleshooting
Source: src/routes/docs/optimal/troubleshooting/+page.md
Description: Fixes for common Optimal problems - no credits, no workspace, a missing machine, attachments, harness sign-in, taking over, and API errors.

Each entry starts with what you see, then the fix.

## In the console

### "Optimal runs on credits"

Optimal needs a positive credit balance, and yours is empty.
Press **Add credits**, or **Upgrade** for a plan with credits, then send again.
In the brain picker the same state reads "Add credits to use Optimal".

A harness or saved agent does not use credits for its model, so you can still use one of those.

### "Choose or create a workspace to start an isolated Optimal chat."

No workspace is selected.
Pick one in the workspace switcher.
Under **All workspaces**, Optimal reads every workspace but asks which one to use before it changes anything.

### Investigate is greyed out

Investigate always runs on the Optimal brain.
The chat's brain is a harness or a saved agent, and a chat keeps its brain.
Start a new chat with **New** and pick Optimal.

### The brain picker will not change

The brain is fixed after the first message.
Picking a different brain starts a new chat.

### A harness shows "Not connected" or "Needs signing in again"

Press **Connect** or **Reconnect** on its row in the brain picker, sign in, and you return to Optimal.
See [Harnesses and auth](/docs/agents/harnesses/).

### "This chat's machine was deleted. Pick another, or let Optimal choose."

The sandbox or computer bound to the chat no longer exists.
Pick a machine in the machine menu, or send in Build mode and choose **New sandbox**.

### "... is kept on this chat's machine: pick a sandbox or computer, then send again."

The file is not an image or a document, so it is written to the chat's machine, and the chat has none.
Pick a machine in the machine menu, then send the file again.
Files are limited to 10 MB each and 25 MB per chat.

### "Interrupted. The reply stopped early."

The reply was cut off before it finished.
Press **Try again** next to the note; the chat keeps everything before it.

### "Couldn't take over. Try again." or "Couldn't hand it back. Try again."

The machine did not answer in time.
Wait a moment and press **Take over** or **Hand back** again.
Check the **Machine** tab to see that the machine is running.

### Publish is not available

The machine has to be running to publish.
Resume it from the **Machine** tab or the machine menu, then press **Publish** again.

### The context meter is red

The chat has used most of its 1M-token context.
Nothing is needed: Optimal folds the older part into a summary on its own and shows "Compacting context..." while it does.

## Over the API

| You get | Fix |
|---|---|
| `401` with `MISSING_TOKEN` | Send `Authorization: Bearer `, not your API key |
| `401` on a call that worked before | The Optimal token expired after 10 minutes; mint a new one |
| `403 FORBIDDEN` when minting | Give the API key the `osa:write` permission |
| `403 API_KEY_WORKSPACE_BOUND` | Mint the token for the workspace the key is bound to |
| `403 approval_scope_required` | Give the API key the `osa:approve` permission, then mint a new token |
| `402 OPTIMAL_CREDITS_REQUIRED` | Add credits or upgrade |
| `404 session_not_found` | The chat id is wrong, deleted, or in another workspace; check the token's workspace |
| `409 machine_switch_requires_confirmation` | Send the message again with `"confirm_switch": true` |
| `409 machine_unavailable` | Start the machine, then retry |
| `409 no_machine` on an upload | Bind a machine with `POST /sessions/{id}/machine` first |
| `415 unsupported_media_type` | Add `Content-Type: application/json` |
| `429 rate_limited` | Wait for the `Retry-After` seconds |
| A stream that shows nothing | Open the stream before you send, or read finished turns from `GET /sessions/{id}/messages` |

See the [Optimal API](/docs/optimal/api/) for every endpoint.

# Tasks, artifacts and history

URL: https://miosa.ai/docs/optimal/workspace
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/optimal/workspace
Source: src/routes/docs/optimal/workspace/+page.md
Description: The Optimal sidebar pages - Tasks, Investigations, Artifacts, Approvals, History, Usage and Preferences - and what each one keeps for you.

Inside Optimal, the sidebar switches to Optimal's own pages.
Each page shows the current workspace.

| Page | What it keeps |
|---|---|
| **New** | Starts a fresh chat |
| **Tasks** | What Optimal took on in your chats, grouped by chat |
| **Investigations** | The investigations Optimal ran, with their evidence |
| **Artifacts** | Everything Optimal produced for you |
| **Approvals** | Approvals across your chats; see [Approvals](/docs/optimal/approvals/) |
| **History** | Every chat, and what Optimal did in the workspace |
| **Usage** | Spend and tokens; see [Pricing and usage](/docs/optimal/pricing/) |
| **Preferences** | Approvals, memory, chat history, notifications, and sign-ins |

## Tasks

Tasks lists what Optimal took on, grouped by the chat it came from.
The page refreshes while something is still running.
A running group of tasks can be cancelled from here.

When there are none yet, the page reads "No durable tasks yet".
Ask Optimal to investigate, plan, or operate something and its task appears.

## Investigations and Artifacts

Both pages have a search box and a status filter.

- **Review investigation** opens an investigation and the evidence behind it.
- **Open artifact** opens something Optimal produced, such as a report or a file.

When a list is empty, **Start in Optimal** opens a new chat.

## History

History lists every chat in the workspace.
Search by title, open a chat to pick it up again, or use **Load older chats** to go further back.
Each row has a menu to rename or delete the chat, and **Copy chat ID**.

Below the chats, **Workspace events** lists what Optimal did in the workspace.

## Preferences

| Section | Setting | Options |
|---|---|---|
| Approvals | Ask before | Every step, Changes only, Deletions only |
| About you | Remember across chats | On or off; your saved memories are listed with **Delete** |
| Chat history | Keep chats for | 30 days, 90 days, 1 year |
| Notifications | Needs your approval, Work finished | On or off |
| Sign-ins | Saved sign-ins | Masked site names, with **Remove** |

Memories are yours: only you see them, and only in this workspace.
Turn **Remember across chats** off to stop Optimal keeping new ones.

Chats older than the **Keep chats for** setting can no longer be resumed.

# Plans and limits

URL: https://miosa.ai/docs/plans-and-limits
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/plans-and-limits
Source: src/routes/docs/plans-and-limits/+page.md
Description: The four MIOSA plans, what each includes, and the limits per service and per account.

# Plans and limits

There are four plans.
Every plan pays the same published price for a size.
Plans differ in what they include and in how much you can run.

| Plan | Price | Included usage each month | Past the included usage |
|---|---|---|---|
| Free | $0 | $1 | Stops at $1. Add credits to keep going. |
| Developer | $20/mo | $20 | Pay as you go. Add credits any time. |
| Business | $500/mo | $500 | Pay as you go. Add credits any time. |
| Enterprise | $2,000/mo | $2,000 | Pay as you go, invoiced |

Pick a plan in [Billing](/billing).
Free works for a first try.

## Per service

A service's replicas, size and storage are limited by your plan.

| Plan | Replicas | Largest replica | All replicas together | Always-on | Volume | Image |
|---|---|---|---|---|---|---|
| Free | 1 | 1 vCPU, 0.5 GB | 0.5 GB, 1 vCPU | No, it sleeps | 0.5 GB | 4 GB |
| Free with added credits | 2 | 2 vCPU, 2 GB | 2 GB, 2 vCPU | No, it sleeps | 2 GB | 8 GB |
| Developer | 4 | 4 vCPU, 8 GB | 16 GB, 8 vCPU | Yes | 10 GB | 20 GB |
| Business | 10 | 8 vCPU, 16 GB | 64 GB, 32 vCPU | Yes | 250 GB | 50 GB |
| Enterprise | 20 | 16 vCPU, 32 GB | 128 GB, 64 vCPU | Yes | 1 TB | Unlimited |

## Per account

These totals count everything running at once: services, sandboxes, computers and databases.

| Plan | Running memory | Running vCPU | Projects | Sandboxes | Computers | Databases | Egress per month | Seats |
|---|---|---|---|---|---|---|---|---|
| Free | 2 GB | 2 | 1 | 1 (stops after 30 minutes) | 1 small, hibernates after 15 idle minutes | 1 small | 5 GB | 1 |
| Free with added credits | 6 GB | 4 | 2 | 2 (stop after 2 hours) | 1, up to 2 vCPU and 4 GB | 2 | 20 GB | 1 |
| Developer | 32 GB | 16 | 10 | 5 | 3 | 5 | 100 GB | 1 |
| Business | 128 GB | 64 | Unlimited | 25 | 20 | 25 | 1 TB | 10 |
| Enterprise | 256 GB | 128 | Unlimited | 100 | 100 | 100 | 5 TB | Unlimited |

Enterprise totals can be raised by agreement.

## Free with added credits

A Free account can add credits, from $5.
Added credits never expire.
While the added balance is above $0, the "Free with added credits" limits apply.
When it reaches $0, the account is back on the Free limits.

## Dedicated vCPU

Dedicated vCPU sizes are for Business and Enterprise.
See [Dedicated vCPU](/docs/services/dedicated-vcpu).

## When you reach a limit

A create or a deploy that would pass a limit is refused with an error that names the limit and the plan that raises it.
Nothing running is stopped.
Your limits and usage are in [Billing](/billing).

## Guardrails

Two limits sit above the plan tables, and both are there to keep the fleet honest:

- **Running memory per organization.** No organization runs more than about
  100 GB of memory at once without an administrator override, whatever its plan.
- **Fleet pressure.** When the committed memory on the fleet passes 80% of what
  is free, new Free creates pause and new Free signups queue until capacity
  returns. Paid creates continue. Nothing already running is stopped.

## Where to go next

- [Pricing](/docs/pricing): the per-size rates every plan pays.
- [Credits](/docs/api-reference/credits): how credits are bought, spent and expire.

# Agent credit metering

URL: https://miosa.ai/docs/platform/agent-credit-metering
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/agent-credit-metering
Source: src/routes/docs/platform/agent-credit-metering/+page.md
Description: How to meter credits for MIOSA agent runs, model usage, devices, tools, storage, and deployments.

# Agent credit metering

Credits are the business model for agent work on MIOSA. A user does not buy
"a sandbox" or "a model call" in isolation. They buy credits that power agents
doing useful work on devices.

```text
credits = model usage + device runtime + tools + storage + deployments
```

Use this page when building billing, quotas, usage pages, workspace budgets,
or white-label credit systems.

---

## Metered surfaces

| Surface | Examples | When charged |
|---|---|---|
| Model/runtime | OSA, Codex, Claude Code, Hermes, custom model calls | During agent reasoning and tool planning |
| Sandbox runtime | CPU/RAM while sandbox is running | While executing, previewing, installing, building |
| Computer runtime | Cloud desktop/browser time | While browser/desktop session is active |
| Local relay | Secure relay, streaming, tunnel, control channel | While paired local device is connected through MIOSA |
| Tool calls | Browser actions, web search, Refero, connector token requests | Per call or per run allocation |
| Storage | Snapshots, artifacts, logs, persistent files | By size and retention |
| Deploy hosting | MIOSA Deploy, Docker Host, domains, always-on app runtime | While deployed or always-on |

Even if each subsystem records internal metrics, customer-visible billing should
land in one credit ledger with workspace, user, run, agent, and device context.

---

## Ledger shape

```sql
credit_ledger
  id
  tenant_id
  workspace_id
  project_id
  user_id
  agent_id
  run_id
  device_type
  device_id
  category
  units
  unit_price_credits
  credits
  metadata_json
  created_at
```

Recommended categories:

```text
model
device_runtime
tool
connector
storage
deployment
network
adjustment
grant
refund
```

Each ledger entry should be traceable to a run, request id, or lifecycle event.

---

## Run-level cost model

Every agent run should expose:

| Field | Purpose |
|---|---|
| `estimated_credits` | Show before high-cost work starts |
| `reserved_credits` | Prevent a run from exceeding budget mid-flight |
| `credits_used` | Final charge |
| `credit_breakdown` | Explain model/device/tool/storage/deploy split |
| `budget_remaining` | Let UI warn before next action |

---

## Simple examples

### One-shot health check

```text
User runs: miosa run "check preview"

Charges:
  model: small
  device_runtime: seconds
  storage: none
  deploy: none
```

### Sandbox app generation

```text
User asks: "Build a Next.js marketing page."

Charges:
  model: planning and code generation
  sandbox_runtime: install, build, preview
  storage: files, logs, snapshot
  deployment: only if user publishes
```

### Browser automation

```text
User asks: "Log in and test checkout."

Charges:
  model: browser planning
  computer_runtime: browser session
  tool: screenshots and browser actions
  storage: screenshots/report artifact
```

### Agent-company workflow

```text
User asks: "Launch this company campaign."

Charges:
  parent model run
  child model runs
  multiple sandboxes/computers
  connectors
  artifacts
  optional deployment
```

---

## Budget policies

Workspace owners should be able to set:

- monthly credit budget
- per-run max credits
- per-agent daily budget
- max concurrent sandboxes
- max concurrent computers
- max child agents
- max connector spend
- approval threshold
- hard stop threshold

Recommended approval gates:

| Action | Gate |
|---|---|
| Use more than run budget | Ask approval |
| Create many child devices | Ask approval |
| Start always-on deployment | Ask approval |
| Use paid connector | Ask approval or preconfigured policy |
| Send external messages | Ask approval |
| Delete snapshots/artifacts | Ask approval |

---

## Credits in white-label products

White-label products can expose credits in two ways:

| Model | Meaning |
|---|---|
| Pass-through | End customer sees MIOSA credit usage directly |
| Wrapped | Your product shows its own units, while backend maps to MIOSA credits |

For Lumen-style products, the backend should store both:

```sql
customer_usage_events
  external_workspace_id
  external_user_id
  external_project_id
  miosa_run_id
  miosa_credits
  customer_units
```

This lets your app show the product-specific balance while still reconciling to
MIOSA billing.

---

## Credit events

Emit events so the UI can update live:

| Event | When |
|---|---|
| `credits.estimated` | Before a run, publish, or expensive connector action |
| `credits.reserved` | Budget held for a run |
| `credits.charged` | Ledger entry committed |
| `credits.refunded` | Failed or cancelled work refunded |
| `credits.low_balance` | Workspace balance below threshold |
| `credits.limit_reached` | Run blocked by plan or budget |

The CLI should report the same data:

```bash
miosa billing balance
miosa workspace usage <slug>
miosa run usage <run-id>
miosa whoami --json
```

---

## Failure handling

Billing should be conservative and explainable.

| Failure | Expected billing behavior |
|---|---|
| Run rejected before start | No charge |
| Device created but agent failed before work | Charge minimal device time or refund per policy |
| Upload/import failed after resource creation | Return partial resource id and recovery command |
| User cancels | Charge work already performed, stop future charging |
| Platform error | Refund affected usage where possible |
| Connector/provider error | Charge only completed provider work |

Always include request ids and run ids in billing-support views.

# Agents in your product

URL: https://miosa.ai/docs/platform/agents-in-your-product
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/agents-in-your-product
Source: src/routes/docs/platform/agents-in-your-product/+page.md
Description: Give each of your users a machine with an agent or harness working inside it, and show the result in your own UI.

# Agents in your product

A platform makes a machine for each of your users, then puts an agent or harness inside it.
The agent writes files, runs commands, and opens ports.
Your product shows the result: a preview URL, a terminal, or a screenshot.

## One machine per user

One sandbox or computer per end user, never shared across customers.

Each machine has its own filesystem, network, and process tree.
Pick sandboxes for code and previews, and computers when an agent needs a desktop or browser: [Agent device selection](/docs/guides/agent-device-selection/).

A code agent gets a sandbox, and a browsing agent gets a computer.
Both get their own filesystem and network.

## Let your user bring their own model account

An agent run thinks with an account that belongs to its owner.
Your customer can connect their own Claude plan, ChatGPT plan or model key from inside your product, with no console visit.
Every run on their machines then uses it, before the workspace's.

```typescript
const signin = await miosa.connections.connectSubscription({ provider: "claude", externalUserId: "cus_123" })
// show signin.verificationUrl in your UI, then: await signin.submitCode(pastedCode)
```

See [Connect agent accounts](/docs/guides/connect-agent-accounts/).

## Show the result to your user

The browser only ever sees preview URLs and scoped, expiring tokens.
Mint short-lived [browser tokens](/docs/platform/browser-tokens/) for previews and terminals.

To show a preview inside your product, mint a share token on the server and send only the URL to the browser:

```typescript
// GET /embed-url on your backend
const share = await sandbox.previews.share(preview.id, { expiresInSec: 3600 })
return { embedUrl: share.share_url }
```

The token is bound to that one preview and expires.

Never put an `msk_*` key in a browser.
Treat it like a Stripe secret key: server-only, rotated on a schedule, audited.

Always display the returned `public_url` instead of building hostnames yourself.

## Next


    Run an AI agent against a sandbox or computer.


    Dispatch work, stream events, and collect artifacts.


    Keys and subscription plans for your workspace or for each end user.


    Short-lived tokens for previews and terminals in the end user's browser.


    Choose a sandbox or a computer for each agent.

# API Keys

URL: https://miosa.ai/docs/platform/api-keys
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/api-keys
Source: src/routes/docs/platform/api-keys/+page.md
Description: User and platform API keys for personal tools, backend automation, and scoped MIOSA API access.

An **API key** authenticates a person or backend service to MIOSA.
User keys are personal credentials.
Platform keys are tenant automation credentials and can optionally be restricted to one workspace.

## Create a key

From the dashboard: **Workspace → Settings → API Keys → New key**. Or via API:
```http
POST /api/v1/api-keys
```

```typescript
const key = await miosa.apiKeys.create({
  name: "Lumen backend prod",
  key_type: "platform",
  workspace_id: workspaceId,
  scopes: ["deployments:write", "sandboxes:write", "domains:write"],
})

console.log(key.key)  // shown once
// -> msk_p_a1b2c3d4...
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

key = miosa.api_keys.create(
    name="Lumen backend prod",
    key_type="platform",
    workspace_id=workspace_id,
    scopes=["deployments:write", "sandboxes:write", "domains:write"],
)

print(key["key"])  # shown once
# -> msk_p_a1b2c3d4...

# List all keys (tokens are NOT shown in list responses)
for k in miosa.api_keys.list():
    print(k["id"], k["name"])

# Revoke a key
miosa.api_keys.delete(key["id"])
```

The plaintext `msk_*` value is returned **exactly once** at creation.
The dashboard shows only a prefix and last four characters thereafter.
The server stores only a SHA-256 hash.

If you lose a key, rotate  -  create a new one, swap it in, delete the old.

## Key families
```

msk_<type>_<random>
```

- `msk_u_*` - user-bound keys for personal CLI and SDK use.
- `msk_p_*` - tenant platform keys for server-side automation.
- `msk_a_*` - operator-admin keys that are not created through the public self-service API.

Environment-labeled key prefixes are not part of the current self-service contract.
Dedicated test-mode billing isolation is planned.

For a server-side platform integration, use a `platform` key created by a tenant owner or administrator.
Never expose it to browser code.

## Scopes

Each key has a list of scopes. MIOSA enforces scopes on every mutation. Reads typically require the matching `:read` scope; writes require `:write`.

Common scopes:

| Scope | Allows |
|---|---|
| `sandboxes:read` | List, get sandboxes |
| `sandboxes:write` | Create, exec, files.write, destroy |
| `deployments:read` | List, get deployments, versions, domains |
| `deployments:write` | Create, publish, rollback, attach domains |
| `domains:write` | Create, verify, delete custom domains |
| `databases:write` | Provision and operate managed databases |
| `storage:write` | Provision and operate object storage |
| `billing:read` | Read billing and credit information |

For server-side platform integration, start with the exact resource scopes the backend needs.
User keys created without an explicit scope list receive the standard product scopes.
Platform keys are trusted tenant automation credentials, so only tenant owners and administrators can create them.

## Permission presets

A preset is a named set of scopes that the platform keeps, so you pick a name instead of maintaining a list.
`GET /api/v1/api-keys/presets` returns every preset with its scopes.
The dashboard offers **Read-only**, **Automation**, **CI**, **Full access** and **Custom** (choose each scope yourself).

```http
POST /api/v1/api-keys
{ "name": "Deploy pipeline", "preset": "ci" }
```

Send either `preset` or `scopes`, not both.
The platform resolves the preset to its current scopes when the key is created, and the key keeps those scopes afterwards.

**Full access** carries every permission.
Use it only for trusted server-side tools, and prefer a service account.
The dashboard offers it only to organization owners and admins.

For production, create keys under a service account.
A service-account key does not depend on one person's membership, and deleting the account revokes all of its keys.

## Rotation

Rotate keys on a schedule (we recommend every 90 days, or on incident). The flow:

1. Create a new key with the same scopes.
2. Roll out the new key to your backend (deploy + restart).
3. Confirm the new key works (recent activity logged with `key_id` of the new key).
### 4. Delete the old key

```typescript
// Step 1: create
const newKey = await miosa.apiKeys.create({ name: "...", scopes: [...] })

// Step 2-3: deploy, confirm.

// Step 4: revoke old
await miosa.apiKeys.delete(oldKeyId)
```

```python
# Step 1: create
new_key = miosa.api_keys.create(name="...", scopes=[...])

# Step 2-3: deploy, confirm.

# Step 4: revoke old
miosa.api_keys.delete(old_key_id)
```

Deleting a key invalidates it immediately. Any in-flight requests using the old key will start getting 401.

## Rate limits

Each key has a server-provided request-per-minute limit.
The current defaults are 600 rpm for user keys and 30,000 rpm for platform keys, but tenant and endpoint-family limits can be more restrictive.

- Key ID (the key's own bucket)
- Tenant or organization
- Endpoint (publish has its own bucket, separate from list operations)

Limits scale with the plan. Headers in every response tell you where you stand:
```

X-RateLimit-Limit: 600
X-RateLimit-Remaining: 547
X-RateLimit-Reset: 1715712060
```

429 responses include a `Retry-After` header. SDKs back off automatically.

## Audit

Every action authenticated by a key emits an audit event with:

- `api_key_id` (so you know which key did what)
- `actor` (the organization, plus the key's name)
- `workspace_id`, `project_id`, `external_workspace_id`, `external_user_id` (if passed or resolved in the request)
- The action (e.g. `deployments.publish`, `domains.create`)
- Timestamp + outcome

Read your audit log via:
```http
GET /api/v1/audit-log?api_key_id=550e8400-e29b-41d4-a716-446655440000
GET /api/v1/audit-log?workspace_id=550e8400-e29b-41d4-a716-446655440000
```

## Browser keys (no)

There is no such thing as a browser-safe `msk_*`. If you need a browser to call MIOSA-like functionality, mint a scoped browser token server-side. See [Browser Tokens](/docs/platform/browser-tokens/).

Unlike Stripe, MIOSA does NOT issue separate `pk_*` publishable keys. Every MIOSA key is a server-side secret. If a third-party SDK or doc tells you to "just use the publishable key in the browser," that's not a MIOSA pattern  -  they're probably using a scoped browser token.

# Resource Ownership and Attribution

URL: https://miosa.ai/docs/platform/attribution
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/attribution
Source: src/routes/docs/platform/attribution/+page.md
Description: Scope resources to MIOSA workspaces and projects while preserving your own workspace / user / project IDs for billing and reconciliation.

Resource ownership is how MIOSA decides where a resource lives. External attribution is how your platform maps that resource back to your own database.

- `workspace_id` and `project_id` are canonical MIOSA ownership. They affect routing, permissions, dashboard grouping, usage, and where resources appear.
- `external_workspace_id`, `external_user_id`, and `external_project_id` are opaque strings from your platform. They are copied to usage, audit, and child resources for reconciliation.

## Ownership fields

| Field | Meaning | Example |
|---|---|---|
| `workspace_id` | Existing MIOSA workspace UUID | `"550e8400-e29b-41d4-a716-446655440000"` |
| `workspace_slug` | Existing or auto-created workspace slug | `"acme-corp"` |
| `workspace_name` | Workspace display name when auto-created | `"Acme Corp"` |
| `project_id` | Existing MIOSA project UUID | `"660e8400-e29b-41d4-a716-446655440001"` |
| `project_slug` | Existing or auto-created project slug inside the workspace | `"lead-magnet"` |
| `project_name` | Project display name when auto-created | `"Lead Magnet"` |

If no workspace selector is supplied, MIOSA uses the organization's default workspace. If no project selector is supplied, MIOSA uses or creates a `default` project inside that workspace.

When you pass `external_workspace_id` or `external_project_id` without a canonical ID/slug, MIOSA resolves the matching workspace/project or creates one for this organization. The response includes `workspace_id` and `project_id`; store those IDs and use them on future calls when possible.

## Attribution fields

| Field | Meaning | Example |
|---|---|---|
| `external_workspace_id` | Your customer/workspace/account ID | `"acct_123"` |
| `external_user_id` | Your end-user ID inside that customer | `"user-456"` |
| `external_project_id` | Your project ID inside that workspace | `"project_789"` |

All three are optional, stored as text, and scoped to the authenticated MIOSA organization. They never grant access.

## How it flows
Diagram:
sequenceDiagram
    participant P as Platform backend
    participant M as MIOSA API
    participant U as Usage records
    participant B as Billing / chargeback

    P->>M: POST /sandboxes<br/>workspace_slug: acme-corp<br/>project_slug: lead-magnet<br/>external_workspace_id: acct_123
    M-->>P: sandbox with workspace_id + project_id
    M->>U: usage event with canonical ownership + external IDs
    P->>M: GET /usage?workspace_id=...
    M-->>P: { total_usd: 4.20, line_items: [...] }
    P->>B: charge acct_123 accordingly

## On every create

Pass ownership and attribution in the request body of create calls:

```typescript
await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceSlug: "acme-corp",
  workspaceName: "Acme Corp",
  projectSlug: "lead-magnet",
  projectName: "Lead Magnet",
  externalWorkspaceId: "acct_123",
  externalUserId: "user-456",
  externalProjectId: "project_789",
})
```

```typescript
await miosa.computers.create({
  template_type: "ubuntu-desktop",
  workspaceId: "550e8400-e29b-41d4-a716-446655440000",
  projectId: "660e8400-e29b-41d4-a716-446655440001",
  externalWorkspaceId: "acct_123",
  externalUserId: "user-456",
  externalProjectId: "records_portal",
})
```

```typescript
await miosa.deployments.publish(deploymentId, {
  sourceSandboxId: sandbox.id,
  workspaceId: sandbox.workspaceId,
  projectId: sandbox.projectId,
  externalWorkspaceId: "acct_123",
  externalUserId: "user-456",
  externalProjectId: "project_789",
})
```

```typescript
await miosa.deployments.domains.add(deploymentId, {
  domain: "program.example.net",
  externalWorkspaceId: "acct_123",
  externalUserId: "user-456",
})
```

Canonical ownership and attribution are stored on the resource row and on every event / audit / usage record produced from that resource.

## Filter by ownership or attribution

List endpoints accept canonical ownership filters and external attribution filters:
```http
GET /api/v1/sandboxes?workspace_id=550e8400-e29b-41d4-a716-446655440000
GET /api/v1/sandboxes?project_id=660e8400-e29b-41d4-a716-446655440001
GET /api/v1/computers?external_project_id=records_portal&status=running
GET /api/v1/deployments?external_user_id=user-456
GET /api/v1/deployments/:id/domains?external_project_id=project_789
```

Filters are organization-scoped server-side. Another MIOSA organization cannot read your resources by guessing the same `workspace_id`, `project_id`, slug, or external ID.

## Inheritance

When a resource is derived from another, ownership and attribution are inherited by default:

- sandbox to preview
- sandbox to deployment
- deployment to build, version, service, release, runtime instance, and domain
- project to database, storage bucket, volume, function, cron job, auth, and integration
- computer to custom domain, usage records, and audit events

```typescript
const sandbox = await miosa.sandboxes.create({
  workspaceSlug: "acme-corp",
  projectSlug: "lead-magnet",
  externalWorkspaceId: "acct_123",
  externalUserId: "user-456",
})

const deployment = await miosa.deployments.publish(deploymentId, {
  sourceSandboxId: sandbox.id,
})

console.log(deployment.workspace_id) // same as sandbox.workspace_id
console.log(deployment.project_id) // same as sandbox.project_id
```

Explicit values on the descendant request override inherited external IDs. Canonical project/workspace IDs must still belong to the authenticated organization.

## Authorization vs ownership vs attribution

Critical distinction:

- **Authorization** is the MIOSA organization. It is derived server-side from your API key or JWT.
- **Ownership** is `workspace_id` and `project_id`. It controls where resources live, but must belong to the authenticated organization.
- **Attribution** is `external_*`. It never authorizes anything. It only groups and filters inside the organization.

If you're building authorization in your own app, check your authenticated app user and the MIOSA organization first. Treat `external_*` as labels for billing, display, and reconciliation.

## Storage and indexing

Ownership and attribution are stored on:

- **Resource tables**: computers, sandboxes, sandbox previews, deployments, deployment versions, deployment builds, deployment environments, deployment services, deployment releases, runtime instances, service bindings, custom domains, databases, storage buckets, volumes, edge functions, cron jobs, preview environments, project auth, and project integrations.
- **Event tables**: usage meters, usage records, sandbox runtime events, and audit events.

Ownership filters are indexed by `tenant_id`, `workspace_id`, and `project_id`. Attribution filters are indexed by `tenant_id` plus the external ID field.

## What to use vs leave null

- Use `workspace_id` / `project_id` when you have already stored MIOSA IDs.
- Use `workspace_slug` / `project_slug` for human-readable integration code.
- Use `external_workspace_id` and `external_project_id` when your own database already has customer/project IDs.
- Use `external_user_id` when one end user triggered the action.

For white-label platforms, the best default is to pass canonical ownership and all three external IDs.

# Browser Tokens

URL: https://miosa.ai/docs/platform/browser-tokens
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/browser-tokens
Source: src/routes/docs/platform/browser-tokens/+page.md
Description: Short-lived scoped credentials your backend mints for end-user-facing access. Never expose `msk_*` to the browser.

When your end-user's browser needs direct MIOSA access  -  previewing a sandbox, opening a terminal, uploading a file  -  mint a short-lived browser token server-side and hand only that to the browser. The workspace API key (`msk_*`) never leaves your backend.

## The mint flow

Diagram:
sequenceDiagram
    participant BR as Browser
    participant BE as Your Backend
    participant MI as MIOSA

    BR->>BE: show preview
    BE->>MI: POST /previews/:id/share (msk_* key)
    MI-->>BE: preview_token + share_url
    BE-->>BR: share_url
    BR->>MI: GET share_url (token in query)
    MI->>MI: validate token, check scope + expiry
    MI-->>BR: preview content

## The pattern

The token is resource-bound (one preview), short-lived (configurable; default 1 hour), and never grants access to anything beyond the resource it was minted for.

## Preview share tokens (the main one)

The most common browser-facing flow.

```typescript
// Inside your authenticated request handler
const share = await miosa.sandboxes.previews.share(previewId, {
  expiresInSec: 3600,
})

res.json({
  share_url: share.share_url,
  expires_at: share.data.share_token_expires_at,
})
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes/$SBX/previews/$PREVIEW/share \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -d '{"ttl_seconds": 3600}'
```

Response:
```json
{
  "data": {
    "id": "preview_...",
    "share_token_prefix": "first12chars",
    "share_token_expires_at": "2026-05-14T19:30:00Z"
  },
  "preview_token": "miosa_pv_<one-time-raw-token>",
  "share_url": "https://5173-abc12345.sandbox.miosa.ai?preview_token=miosa_pv_<one-time-raw-token>"
}
```

Front-end:
```jsx
// React example
<iframe
  src={shareUrl}
  sandbox="allow-same-origin allow-scripts allow-forms"
  className="w-full h-[600px] border-0"
/>
```

The token authenticates the request at MIOSA's edge proxy. The proxy strips the credential before forwarding to your dev server on the sandbox  -  your application code never sees it.

## Token formats

| Use case | Where it goes | Lifetime |
|---|---|---|
| Preview share | `?preview_token=...` query string | configurable (default 1h, max 7 days) |
| Terminal session | `wss://...?token=...` WebSocket query | typically 5-30m |
| Upload session | `Authorization: Bearer miosa_up_...` | minutes |
| Generic resource token | TBD | scoped per resource |

All formats are JWTs signed by MIOSA. The payload includes the resource ID, scopes, expiry, and an HMAC the proxy verifies. You can decode them client-side to inspect the expiry but you cannot forge them.

## Lifetime and expiry
```typescript
const share = await miosa.previews.share(previewId, {
  expiresInSec: 3600, // 1 hour
})
```

Share tokens default to 1 hour and can be set from 60 seconds up to 7 days. Longer TTL means more risk if a token leaks; for browser embedding 1-3 hours is typical.

After expiry the preview returns 401. Your frontend should:

1. Watch `share.data.share_token_expires_at`.
2. Mint a new token before expiry by re-calling your backend.
3. Reload the iframe with the new `share_url`.

## Re-minting and revoking

A preview can have **multiple active share tokens** at the same time. Minting a new one does not invalidate previous ones.

To revoke all tokens for a preview, hit:
```http
DELETE /api/v1/sandboxes/:id/previews/:preview_id/share
```

This invalidates every outstanding share token for the preview. Useful for "I accidentally shared this externally, kill all browser access immediately."

## CSP and embedding

MIOSA's preview proxy emits `Content-Security-Policy` headers that allow the preview to be embedded as an iframe under specific origins. By default:

- `*.miosa.app`
- `*.miosa.ai`
- `localhost:4000` (for local dev of MIOSA frontend)

For white-label embedding (your platform served at `app.example.com` embedding MIOSA previews), the CSP needs to include your origin. Contact support to configure the proxy CSP per tenant.

## Audit

Every token issuance emits an audit event:
```json
{
  "action": "preview.share_token.issued",
  "resource_id": "preview_...",
  "actor": "api_key:msk_u_...",
  "metadata": {
    "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
    "project_id": "660e8400-e29b-41d4-a716-446655440001",
    "external_workspace_id": "acct_123",
    "external_user_id": "user-456",
    "expires_at": "2026-05-14T19:30:00Z",
    "token_prefix": "miosa_pv_xyz"
  }
}
```

`token_prefix` lets you correlate audit events to log entries without storing the raw token.

## What browser tokens cannot do

- Cannot make MIOSA API calls (sandboxes.create, deployments.publish, etc.). They're proxy-only.
- Cannot escalate to a different resource. A preview token for `preview_A` cannot read `preview_B`.
- Cannot cross tenants.
- Cannot persist past expiry. A revoked or expired token is permanently dead.

If you need broader browser-side access (e.g. a developer dashboard your end users log into), use a full MIOSA user session (JWT) instead. See [Authentication](/docs/authentication/).

The raw token grants iframe access. Treat it like a session cookie  -  don't log it server-side or pass it through analytics tools. The `share_token_prefix` is safe to log.

# Platform builder guide

Source: src/routes/docs/platform/overview/+page.md
Description: Run your users' agents, previews, and workspaces on MIOSA: architectures, costs, and provisioning patterns.

# Platform builder guide

MIOSA gives you machines, previews, and deployments.
A platform is what you build on top of them so that other people can use them without ever learning how they work.

This guide is for builders of products like Lovable, Devin, or agent platforms.
In these products, your product makes a sandbox for each of your own users.

Such a platform needs:

- A sandbox per user or project: [Patterns](/docs/platform/patterns/).
- A private preview URL of what the user builds: [Branding and domain setup](/docs/platform/white-label/).
- An agent or harness working inside the machine: [Agents in your product](/docs/platform/agents-in-your-product/).
- Deployments and Docker Host: [Deploy overview](/docs/docker-host/overview/).
- White-label, tenants, scoped tokens, and external users: [Branding and domain setup](/docs/platform/white-label/) and [Ownership and attribution](/docs/platform/attribution/).
- Billing and caps: [Templates and sizing](/docs/platform/templates-and-sizing/).

## Choose a shape

Every platform on MIOSA uses one model.
Three shapes cover most products.

| You are | Example | Who uses it | What is white-labeled |
|---|---|---|---|
| A SaaS shipping an agent product | **Lumen** | Lumen's customers | Everything: domains, branding, billing |
| An agency running client work | **Northwind Agency** | Northwind's clients | Client previews and delivery domains |
| A company with a team | **Acme Corp** | Acme's own staff and agents | Nothing. It is internal |

If you only need the internal case, jump to [Acme Corp: an internal platform](/docs/platform/patterns/#acme-corp-an-internal-platform).

## Northwind Agency: client work

The full architectures - Lumen, Northwind Agency client work, and Acme Corp - are walked in [Patterns](/docs/platform/patterns/).

## 1. Create a scoped platform key

Platform keys (`msk_p_*`) are for server-side automation.
Only tenant owners and administrators can create them.
Give each key only the scopes the backend needs, and optionally restrict it to one workspace.

```typescript
const key = await miosa.apiKeys.create({
  name: "Lumen backend prod",
  key_type: "platform",
  workspace_id: workspaceId,
  scopes: ["sandboxes:write", "deployments:write", "domains:write"],
})

console.log(key.key) // shown once, store it in your secret manager
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

key = miosa.api_keys.create(
    name="Lumen backend prod",
    key_type="platform",
    workspace_id=workspace_id,
    scopes=["deployments:write", "sandboxes:write", "domains:write"],
)

print(key["key"])  # shown once
```

The plaintext is returned exactly once and MIOSA stores only a hash.
Rotation, scopes, and audit are covered in [API keys](/docs/platform/api-keys/).

## 2. Create a workspace per customer

Do this once, when the customer signs up, and store the returned IDs next to your own row.

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const workspace = await miosa.workspaces.create({
  name: "Northwind Agency",
  slug: "northwind-agency",
  externalWorkspaceId: "acct_123",
})
```

```python

client = miosa.Miosa(api_key=os.environ["MIOSA_API_KEY"])

workspace = client.workspaces.create(
    name="Northwind Agency",
    slug="northwind-agency",
    external_workspace_id="acct_123",
)
```

You can also skip this step.
If a create call carries `workspace_slug` or `external_workspace_id` and the workspace does not exist, MIOSA resolves or creates it.
The response returns the canonical `workspace_id` and `project_id`, so store those and reuse them.
Details in [Ownership and attribution](/docs/platform/attribution/).

## 3. Give each user a machine

One sandbox or computer per end user, never shared across customers.

```typescript
const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceId: workspace.id,
  projectSlug: "booking-portal",
  projectName: "Booking Portal",
  externalUserId: user.id,         // your end user
  externalWorkspaceId: "acct_123", // your customer
})
```

```python
sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    workspace_id=workspace.id,
    project_slug="booking-portal",
    project_name="Booking Portal",
    external_user_id=user.id,
    external_workspace_id="acct_123",
)

# Everything in one customer's workspace
mine = client.sandboxes.list(workspace_id=sandbox.workspace_id)
```

Each machine has its own filesystem, network, and process tree.
Sizing, templates, and idle defaults are in [Templates and sizing](/docs/platform/templates-and-sizing/).

## Pick what you need

| You want to | Page |

# Platform patterns

Source: src/routes/docs/platform/patterns/+page.md
Description: The three architectures that cover most products on MIOSA, plus the model and backend jobs every platform shares.

# Platform patterns

This guide shows the one model that every platform shares, then walks three concrete shapes:

Every platform on MIOSA shares one model.
This page shows that model plus the three concrete shapes: a white-label SaaS, an agency, and an internal team.

## The model

Every shape uses the same four ideas.

1. **Organization.** Your account on MIOSA. It owns the key, the balance, and the single bill.
2. **Workspace.** A boundary inside the organization. One per customer, client, or team.
3. **Project.** A thing someone is building inside a workspace. Sandboxes, computers, databases, deployments, and domains belong to a project.
4. **Your own IDs.** Opaque `external_*` strings from your database, copied onto every resource, usage event, and audit entry so you can reconcile with your own records.

Diagram:
flowchart TB
  O["Organization<br/>one account, one bill"] --> K["Platform key<br/>server-side, scoped"]
  O --> W1["Workspace<br/>customer, client, or team"]
  O --> W2["Workspace<br/>customer, client, or team"]
  W1 --> P1["Project"]
  P1 --> R["Sandboxes, computers, databases,<br/>deployments, domains"]

Workspaces and projects decide routing, permissions, dashboard grouping, and usage.
Your `external_*` IDs are only labels.
Another organization cannot read your resources even if it knows the same slug or external ID.

## Your backend is the platform

Your users never talk to MIOSA directly.
Your backend does.

Diagram:
flowchart LR
  U[Your users] --> A[Your app]
  A --> B["Your backend<br/>holds the platform key"]
  B --> M[MIOSA API]
  M --> S[Sandboxes and computers]
  S --> P[Previews and deployments]
  P --> A

The backend owns five jobs:

1. Map each of your users or customers to a MIOSA workspace and project.
2. Create sandboxes, computers, deployments, databases, and domains for them.
3. Mint short-lived [browser tokens](/docs/platform/browser-tokens/) for previews and terminals.
4. Query usage for chargeback.
5. Verify webhook signatures.

The browser only ever sees preview URLs and scoped, expiring tokens.

Never put an `msk_*` key in a browser. Treat it like a Stripe secret key: server-only, rotated on a schedule, audited.

## Name the organization

The organization slug is created once, from the organization name, and cannot change.
It appears in MIOSA-managed URLs until you attach your own domain, so set it before users create anything.
See [Branding and domain setup](/docs/platform/white-label/#1-organization-identity).

## Put your brand on it

Branding has three layers, and each is configured separately.

| Layer | What it controls | Where |
|---|---|---|
| Preview domain | `5173-sbx01j9x.sandbox.example.com` instead of a MIOSA URL | [Preview domain](/docs/platform/white-label/#4-organization-preview-domain) |
| Deployment domain | `lead-magnet.apps.example.com` for published apps | [Deployment domain](/docs/platform/white-label/#5-deployment-domain) |
| Exact custom domain | `program.example.net` on one deployment or computer | [Custom domains](/docs/platform/white-label/#6-resource-custom-domains) |

Exact domains win over the deployment domain, which wins over the MIOSA fallback (`lead-magnet.example-org.miosa.app`).
Tenant branding also controls the logo, wallpaper, support URL, and whether "Powered by MIOSA" shows.
Always display the returned `public_url` instead of building hostnames yourself.

## Lumen: a white-label SaaS

Lumen is a made-up company, and `example.com` and `example.net` are reserved example domains, not real ones.
Lumen sells an agent product.
Its customers sign up on `example.com`, describe an app, and get a running preview and a deployment.
They never see MIOSA.

- **Organization:** `Lumen`, one platform key on Lumen's backend.
- **Workspace per customer:** Acme Corp is `acme-corp`, Northwind Agency is `northwind-agency`.
- **Domains:** previews on `*.sandbox.example.com`, deployments on `*.apps.example.com`, and a customer's own `program.example.net` where they ask for it.
- **Billing:** Lumen reads usage grouped by `external_workspace_id` and charges each customer its own price.

```text
Organization: Lumen
  Workspace: Acme Corp
    Project: Summer lead magnet   ->  program.example.net
  Workspace: Northwind Agency
    Project: Booking portal
```

## Northwind Agency: client work

An agency does not sell a product.
It delivers work, and it wants every client kept apart and every client's cost visible.

- **Organization:** `Northwind Agency`, one account that pays for everything.
- **Workspace per client.** A client's machines, databases, deployments, and spend never mix with another client's.
- **Project per engagement.** A website, a booking portal, a campaign page.
- **Delivery:** each finished project is deployed and attached to the client's own domain, with the agency's name on the preview URL while the work is in review.
- **Cost:** query usage per workspace and put it on the client's invoice or retainer report.

Northwind can run this on its own organization with the CLI and dashboard.
It only needs the platform pieces (keys, browser tokens, per-user quotas) once it lets clients log in and iterate themselves.

## Acme Corp: an internal platform

Acme Corp is not launching anything.
It wants its team and its agents to work on one platform that the company owns.

- **Organization:** `Acme Corp`. It pays, owns the balance, and sets who can do what.
- **Workspace per team:** Ops, Engineering, Sales. Each team's machines and apps live there.
- **A machine per agent.** A code agent gets a sandbox, and a browsing agent gets a computer. Both get their own filesystem and network.
- **Connections and secrets** are managed centrally, so a new machine starts with exactly what it should have, and no teammate pastes a vendor token.
- **Domain:** internal apps run behind a company hostname such as `agents.example.net`.

```bash
miosa workspace create Ops
miosa create ops-agent --template miosa-sandbox --workspace ops --env prod --wait
miosa workspace usage ops
```

There is no white-label layer, no end-user browser tokens, and no resale billing.
Everything else in this guide still applies, in particular scoped keys for automation and per-workspace usage.
The full walkthrough, with connections, environments, and access control, is in [Build an internal Business OS for your team](/docs/guides/internal-business-os/).

## Production checklist

**Security**

- The key lives only in your backend, injected from a secret store. Rotate it on a schedule.
- Never sign an end user's request with it. Mint a scoped browser token instead.
- Verify the webhook signature on every delivery.
- Keep your own user database as the source of truth for authorization. MIOSA ownership is for routing and grouping.

**Isolation and quotas**

- One machine per end user.
- Set per-user limits so one account cannot exhaust the organization's capacity: [Quotas](/docs/api-reference/quotas/).
- Cap concurrency and runtime, and set idle timeouts so unused machines pause.

**Abuse**

- Apply your own signup checks, rate limits, and terms before you provision.
- Restrict outbound traffic with [Network policy](/docs/security/network/) and review the [audit log](/docs/security/audit-log/) for unexpected hosts.

**Billing**

- Persist `workspace_id` and `project_id` beside your own IDs on first create.
- Query usage every period and enforce your own spend caps.

# Templates and sizing

URL: https://miosa.ai/docs/platform/templates-and-sizing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/templates-and-sizing
Source: src/routes/docs/platform/templates-and-sizing/+page.md
Description: Pick a template and a size for each user's machine, cap concurrency, and set idle defaults so unused machines pause.

# Templates and sizing

Every machine you make for a user needs a template and a size.
This page covers the defaults a platform builder sets, and where the full resource contracts live.

## Templates

A platform typically starts every user's machine from one template.

```typescript
const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceId: workspace.id,
  externalUserId: user.id,
})
```

```python
sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    workspace_id=workspace.id,
    external_user_id=user.id,
)
```

## Sizes and idle defaults

Sizes, named resource contracts, and idle auto-pause defaults are documented once, for every sandbox:

- [Sizing and limits](/docs/develop/sandboxes/sizing/): size names, resource ranges, and the idle auto-pause default.
- [Timeouts](/docs/develop/sandboxes/timeouts/): `timeout_sec`, `always_on`, and `idle_timeout_sec`.
- [Sandbox lifecycle](/docs/develop/sandboxes/lifecycle/): pause, resume, and persistence.

Cap concurrency and runtime, and set idle timeouts so unused machines pause.

## Quotas and caps

One machine per end user.
Set per-user limits so one account cannot exhaust the organization's capacity: [Quotas](/docs/api-reference/quotas/).

## Costs and billing

Every usage event carries the workspace, project, and your `external_*` IDs.
Group by whichever one you charge on.

```typescript
const report = await miosa.usage.report({
  period: { start: "2026-05-01", end: "2026-06-01" },
  groupBy: ["external_workspace_id"],
})

for (const row of report.data) {
  await charge(row.external_workspace_id, row.total_usd)
}
```

MIOSA sends the organization one invoice for everything.
It does not bill your customers.
You decide the markup and charge them on your own system.
Subscribe to signed lifecycle events with `miosa.webhooks.create`, and verify the `x-miosa-signature` HMAC (SHA-256 of the raw body) before acting on a delivery.
See [Usage and billing](/docs/platform/usage-and-billing/) and [Webhooks](/docs/integrations/webhooks/).

Persist `workspace_id` and `project_id` beside your own IDs on first create.
Query usage every period and enforce your own spend caps.

# Usage & Billing

URL: https://miosa.ai/docs/platform/usage-and-billing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/usage-and-billing
Source: src/routes/docs/platform/usage-and-billing/+page.md
Description: Track MIOSA usage per workspace, per project, per external customer, and per user. Chargeback to your customers.

If you're a platform reselling MIOSA capacity, you need to attribute MIOSA costs back to your own customers. MIOSA emits usage events with [resource ownership and external attribution](/docs/platform/attribution/) on every billable action; you query them, group, and chargeback in your own currency / margin model.

Tenant-scoped usage rollup, session usage, summary, workspace usage, and audit-log endpoints are live.
The exact dimensions available in a response depend on the resource and metering source.
Treat missing measurements as unavailable, not zero.

## What's metered

| Dimension | Unit | When emitted |
|---|---|---|
| Sandbox runtime | sandbox-seconds, priced by size | Per-second while running |
| Builder runtime | builder-seconds | During publish |
| Runtime instance runtime | runtime-seconds, measured CPU and memory, capped at the size price | Per-second while serving |
| Static artifact storage | GB-months | Continuously |
| Static artifact bandwidth | GB egress | Per response |
| Object storage (buckets) | GB-months + GB egress | Continuously / per response |
| Managed Postgres | GB-months + connections | Continuously |
| Managed Redis | GB-months | Continuously |
| Ownership and attribution: every event carries `workspace_id`, `project_id`, and the `external_*` fields if present on the source resource |

Computers (desktop product) have a separate metering schema; see [Computers](/docs/computers/overview/) for that side.

## Usage report API
```http
GET /api/v1/usage?period_start=2026-05-01&period_end=2026-06-01
GET /api/v1/usage?workspace_id=550e8400-e29b-41d4-a716-446655440000
GET /api/v1/usage?external_workspace_id=acct_123&period=2026-05
```

```typescript
const report = await miosa.usage.report({
  period: { start: "2026-05-01", end: "2026-06-01" },
  groupBy: ["external_workspace_id"],
})

for (const row of report.data) {
  console.log(
    row.external_workspace_id,
    "$" + row.total_usd.toFixed(2),
    row.line_items
  )
}
```

```python
from miosa import Miosa

miosa = Miosa(api_key="msk_u_...")

# Grouped chargeback report for a billing period
report = miosa.usage.report(
    period_start="2026-05-01",
    period_end="2026-06-01",
    group_by=["external_workspace_id"],
)

for row in report.get("data", []):
    print(row["external_workspace_id"], f"${row['total_usd']:.2f}")

# Single-workspace query for the current period
summary = miosa.usage.report(
    external_workspace_id="acct_123",
)
print(summary)

# Raw per-session events
sessions = miosa.usage.sessions(external_workspace_id="acct_123")
for s in sessions:
    print(s["dimension"], s["qty"])
```

Response shape:
```json
{
  "data": [
    {
      "workspace_id": "550e8400-e29b-41d4-a716-446655440000",
      "project_id": "660e8400-e29b-41d4-a716-446655440001",
      "external_workspace_id": "acct_123",
      "external_user_id": null,
      "external_project_id": null,
      "total_usd": 1.89,
      "line_items": [
        { "dimension": "sandbox_seconds", "qty": 36000, "usd": 0.36 },
        { "dimension": "static_bandwidth_gb", "qty": 38.2, "usd": 1.53 }
      ]
    },
    {
      "external_workspace_id": "acct_456",
      "total_usd": 11.75,
      "line_items": [...]
    }
  ],
  "period": { "start": "2026-05-01", "end": "2026-06-01" },
  "currency": "usd"
}
```

Use `groupBy` to slice by any combination of ownership and external IDs. Typical groupings:

- `["workspace_id"]`  -  per-client workspace
- `["workspace_id", "project_id"]`  -  per-app/project inside a client
- `["external_workspace_id"]`  -  per-customer chargeback
- `["external_workspace_id", "external_project_id"]`  -  per-app within a customer
- `["external_user_id"]`  -  per-user attribution (e.g. for fair-use limits)
- `[]`  -  total for the entire MIOSA organization

## Audit log

Every mutation also emits an audit event with attribution. Different table, separate read endpoint:
```http
GET /api/v1/audit-log?workspace_id=550e8400-e29b-41d4-a716-446655440000
GET /api/v1/audit-log?external_workspace_id=acct_123
GET /api/v1/audit-log?api_key_id=550e8400-e29b-41d4-a716-446655440000
GET /api/v1/audit-log?action=deployments.publish
```

Audit is for security / compliance, usage is for billing. Both share the same ownership and attribution model.

## Quotas and limits

MIOSA enforces quotas at the organization and plan level. You can enforce per-workspace, per-project, or per-user limits in your own app logic, querying usage to make decisions.

Example: Lumen wants to cap each customer account at $50/month. Their backend:

1. Queries `/api/v1/usage?workspace_id=550e8400-e29b-41d4-a716-446655440000&period=current_month`.
2. If `total_usd &gt; 50`, denies new sandbox creation in the Lumen app.
3. Optionally, hits a MIOSA endpoint to suspend the customer's sandboxes (not a single endpoint today; do it client-side by destroying their sandboxes).

MIOSA also exposes external-user quota endpoints at `/api/v1/quotas/external/{external_user_id}`.
Use them when the caller should be prevented from creating more resources after reaching a configured limit.

## Pricing

Every size has one price, the same on every plan; your plan sets limits, never the price. See [Pricing](/docs/pricing) for the rates, or `GET /api/v1/pricing` for the live price list.

## Billing tenancy

Important: your MIOSA bill is one bill. MIOSA charges the organization owner for all usage, regardless of which workspace/project or `external_workspace_id` it came from. Ownership and attribution exist so you can charge your customers. MIOSA does not bill your downstream customers directly.
```

MIOSA -> Lumen:        $X / month, one invoice
Lumen -> acct_123:   $Y / month (markup, your pricing model)
Lumen -> acct_456:   $Z / month
```

# Branding and domain setup

URL: https://miosa.ai/docs/platform/white-label
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/platform/white-label
Source: src/routes/docs/platform/white-label/+page.md
Description: Configure organization slug, workspace/project ownership, preview domains, deployment domains, branding, and resource attribution.

# Branding and domain setup

MIOSA can run behind your product and your customers' domains. The important order is: set the organization identity first, create workspaces/projects for downstream customers, configure preview and deployment domains separately, then attach exact custom domains where a customer needs their own hostname.

---

## Setup flow
Diagram:
flowchart TD
  A[Set organization name] --> B[Organization slug is created once]
  B --> C[Create workspaces for customers]
  C --> D[Create projects inside workspaces]
  D --> E[Create sandboxes, computers, data, and deployments]
  E --> F[Configure preview domain for sandbox previews]
  F --> G[Configure deployment domain for durable apps]
  G --> H[Attach exact customer domains when needed]
  H --> I[Issue browser tokens to end users]

## 1. Organization identity

Every account needs a real organization name. MIOSA derives the organization slug from that name, and the slug is permanent after setup. Do this before letting users create resources.

Example:

| Organization name | Organization slug | Default managed deployment URL |
|---|---|---|
| `Lumen` | `lumen` | `https://lead-magnet.example-org.miosa.app` |

If a newly created account still has a temporary setup slug such as `org-...` or a slug that does not match the organization name, require setup before normal app navigation.

```http
GET /api/v1/platform/tenants/current
Authorization: Bearer msk_u_...
```

If setup is required, update the tenant with the final organization name:
```http
PUT /api/v1/tenants/{tenant_id}
Authorization: Bearer msk_u_...
Content-Type: application/json

{
  "name": "Lumen"
}
```

The API normalizes the slug from `name`. If a `slug` is supplied, it must match the normalized organization name. After setup, `name` and `slug` are immutable.

The organization slug is used in MIOSA-managed URLs until a custom domain is attached. Make the setup screen explicit: "Create your organization name. This creates your permanent MIOSA slug and can only be done once."

## 2. Workspaces and projects

For white-label platforms, use workspaces for downstream customers and projects for the things they build.

Lumen is a made-up company, and `example.com` and `example.net` are reserved example domains.
Replace them with your own.

Lumen example:

```
Organization: Lumen
  Workspace: Acme Corp
    Project: Summer lead magnet
      Sandboxes: generated app previews
      Databases: form submissions
      Deployment: production lead magnet
      Domain: program.example.net
  Workspace: Northwind Agency
    Project: Booking portal
```

Create workspaces and projects directly, or let resource create calls auto-resolve them from `workspace_slug` / `project_slug` or `external_workspace_id` / `external_project_id`.

```http
POST /api/v1/sandboxes
Content-Type: application/json

{
  "template_id": "miosa-sandbox",
  "workspace_slug": "acme-corp",
  "workspace_name": "Acme Corp",
  "project_slug": "summer-lead-magnet",
  "project_name": "Summer Lead Magnet",
  "external_workspace_id": "acct_123",
  "external_user_id": "user-456",
  "external_project_id": "project_789"
}
```

Responses include `workspace_id` and `project_id`. Store those IDs for future calls.

## 3. URL layers

White-label production has distinct URL layers. Do not mix them:

| Resource | Default URL shape |
|---|---|
| Sandbox preview | `https://{port}-{sandbox_slug}.sandbox.{preview_domain}` |
| Computer desktop | `https://{computer_slug}.computer.miosa.ai/desktop/index.html` |
| Durable deployment | `https://{deployment_slug}.{deployment_domain}` |
| Deployment fallback | `https://{deployment_slug}.{organization_slug}.miosa.app` |
| Exact custom domain | `https://customer-owned.example.com` |

For Lumen, a deployment named `Lead Magnet` defaults to something like:

```text
https://lead-magnet.example-org.miosa.app
```

The fallback is always available. If a tenant deployment domain is configured, deployment responses return that branded URL instead. SDKs, CLIs, and frontends should display the returned `public_url` / `url`, not construct hostnames.

## 4. Organization preview domain

Set a tenant preview domain when generated sandbox preview URLs should use your organization's domain instead of the MIOSA fallback.

Example:

```http
PUT /api/v1/tenant/preview-domain
Content-Type: application/json

{
  "preview_domain": "example.com"
}
```

DNS:

| Record type | Name | Value |
|---|---|---|
| `CNAME` | `*` | `proxy.miosa.ai` |

After DNS propagates:

```http
GET /api/v1/tenant/preview-domain/verify
```

Sandbox preview URLs then use:

```text
https://5173-sbx01j9x.sandbox.example.com
```

## 5. Deployment domain

Set a tenant deployment domain when published apps should use your branded production URL base.

Recommended Lumen setup:

```text
*.example.com       CNAME proxy.miosa.ai   (preview domain: record name `*`)
*.apps.example.com  CNAME proxy.miosa.ai   (deployment domain)
```

Then generated URLs look like:

| Surface | Example |
|---|---|
| Sandbox preview | `https://5173-sbx01j9x.sandbox.example.com` |
| Durable deployment | `https://lead-magnet.apps.example.com` |
| Managed fallback | `https://lead-magnet.example-org.miosa.app` |

Current V1 note: public tenant preview-domain routes are exposed. Tenant deployment-domain resolution exists in backend settings/routing; public tenant-level management routes are still operator-managed. Your client code should consume returned deployment `public_url` values.

## 6. Resource custom domains

Attach exact domains when a project, deployment, or computer needs its own public URL.

Examples:

- `example.net` for a website deployment
- `program.example.net` for a lead magnet
- `app.example.net` for an app
- `preview.example.net` for a client-specific preview surface

For deployments:

```http
POST /api/v1/deployments/{deployment_id}/domains
Content-Type: application/json

{
  "domain": "program.example.net"
}
```

For computers:

```http
POST /api/v1/computers/{computer_id}/domains
Content-Type: application/json

{
  "domain": "desktop.example.net"
}
```

The domain response returns DNS instructions and verification status. Exact resource domains take precedence over managed MIOSA URLs.

## 7. Domain precedence

When MIOSA renders or routes a URL, use this mental model:

| Priority | Source | Example |
|---|---|---|
| 1 | Exact resource domain | `program.example.net` |
| 2 | Tenant deployment domain | `lead-magnet.apps.example.com` |
| 3 | MIOSA managed fallback | `lead-magnet.example-org.miosa.app` |

Sandbox preview domains are separate from deployment domains. Computer desktop URLs are separate from both. Exact resource custom domains still win when attached.

## 8. Branding

Tenant branding controls the product UI, desktop wallpaper, logos, support URL, and whether "Powered by MIOSA" is shown.

```http
PUT /api/v1/tenant/branding
Content-Type: application/json

{
  "custom_app_name": "Lumen",
  "custom_logo_url": "https://example.com/logo-dark.png",
  "support_url": "https://help.example.com",
  "desktop_wallpaper_url": "https://example.com/wallpaper.png",
  "powered_by_visible": false
}
```

Wallpaper requirements:

| Property | Value |
|---|---|
| Format | PNG or JPEG |
| Dimensions | 1920 x 1080 recommended |
| File size | Max 5 MB |

## 9. Browser tokens

Never expose an `msk_*` API key in a browser. Your backend creates sandboxes, deployments, and domains, then issues scoped browser tokens for the end user.

```typescript
const token = await client.browserTokens.create({
  workspaceId: "550e8400-e29b-41d4-a716-446655440000",
  projectId: "660e8400-e29b-41d4-a716-446655440001",
  externalWorkspaceId: "acct_123",
  externalUserId: "user-456",
  permissions: ["sandbox:read", "sandbox:exec", "preview:read"],
  ttlSeconds: 3600,
})
```

## Complete setup checklist

- [ ] Require organization setup if the account still has a temporary slug or no organization name.
- [ ] Explain that organization name creates the permanent MIOSA slug one time.
- [ ] Create or auto-resolve workspaces for downstream customers.
- [ ] Create or auto-resolve projects for each app, website, lead magnet, document, or workflow.
- [ ] Store `workspace_id` and `project_id` from create responses.
- [ ] Use returned MIOSA fallback URLs until DNS is configured.
- [ ] Configure preview domain if sandbox previews should use your domain.
- [ ] Configure deployment domain if generated apps should use your domain by default.
- [ ] Attach exact custom domains to deployments or computers when a customer wants their own URL.
- [ ] Apply tenant branding and support links.
- [ ] Issue browser tokens from your backend only.

## End-to-end walkthrough: per-user provisioning

This walkthrough builds a design-tool SaaS where each customer gets an isolated workspace and never sees the MIOSA brand.

### Per-user provisioning

Create one sandbox per customer project. Pass your own IDs so you can look up, filter, and bill these resources later.

```python

def slug_from_name(name: str) -> str:
    return re.sub(r"[^a-z0-9]+", "-", name.lower()).strip("-")[:60] or "project"

sandbox = client.sandboxes.create(
    template_id="miosa-sandbox",
    name=slug_from_name("Brand Refresh 2026"),   # "brand-refresh-2026"
    external_user_id="user_42",                  # your customer's ID
    external_project_id="proj_lumen_1",    # your project's ID
    metadata={
        "customer_id": "user_42",
        "project_name": "Brand Refresh 2026",
        "source": "lumen-whitelabel",
    },
)

print(sandbox.id)     # "sbx_01hzq5pnmpgt6vdwp0r8d23c5n"
print(sandbox.state)  # "provisioning"  -  becomes "running" in ~2 seconds
```

```typescript
function slugFromName(name: string): string {
  return name.toLowerCase().replace(/[^a-z0-9]+/g, "-").replace(/^-|-$/g, "").slice(0, 60) || "project";
}

const sandbox = await client.sandboxes.create({
  templateId: "miosa-sandbox",
  name: slugFromName("Brand Refresh 2026"),   // "brand-refresh-2026"
  externalUserId: "user_42",                 // your customer's ID
  externalProjectId: "proj_lumen_1",   // your project's ID
  metadata: {
    customerId: "user_42",
    projectName: "Brand Refresh 2026",
    source: "lumen-whitelabel",
  },
});

console.log(sandbox.id);     // "sbx_01hzq5pnmpgt6vdwp0r8d23c5n"
console.log(sandbox.state);  // "provisioning"  -  becomes "running" in ~2s
```

**Field reference:**

| Field | Purpose | Example |
|---|---|---|
| `external_user_id` | Your customer's stable identifier. Used for usage rollup, quota checks, and filtering. | `"user_42"` |
| `external_project_id` | Your project's identifier within a customer. | `"proj_lumen_1"` |
| `name` | URL-safe slug that appears in preview URLs until a custom domain is set. | `"brand-refresh-2026"` |
| `metadata` | Arbitrary key-value pairs returned in webhook payloads and API responses. | `&#123;"source": "lumen"&#125;` |

### Pretty URLs

By default, sandbox previews use `*.sandbox.{preview_domain}` after you register your preview domain. To give each sandbox a human-readable subdomain, update the slug after creation:

```python
client.sandboxes.update("sbx_01hzq5...", slug="brand-refresh-2026")
# Preview URL becomes:
# https://3000-brand-refresh-2026.sandbox.example.com
```

```typescript
await client.sandboxes.update("sbx_01hzq5...", { slug: "brand-refresh-2026" });
// Preview URL becomes:
// https://3000-brand-refresh-2026.sandbox.example.com
```

Slugs must be unique within your workspace. If a slug is already taken, MIOSA returns a `409` conflict.

### Customize after create

Update sandbox settings at any time without recreating the VM:

```python
client.sandboxes.update(
    "sbx_01hzq5...",
    slug="brand-refresh-2026",    # pretty URL slug
    timeout_sec=7200,             # idle timeout (2 hours)
    always_on=False,              # allow idle-pause
    metadata={"phase": "v2"},     # merge into existing metadata
)
```

```typescript
await client.sandboxes.update("sbx_01hzq5...", {
  slug: "brand-refresh-2026",
  timeoutSec: 7200,
  alwaysOn: false,
  metadata: { phase: "v2" },
});
```

### Bill by user

Query compute usage keyed to your `external_user_id`. Use this for per-seat billing, usage dashboards, or chargeback reports.

```python
usage = client.usage.get(
    external_user_id="user_42",
    period_start="2026-05-01T00:00:00Z",
    period_end="2026-06-01T00:00:00Z",
)

print(usage["compute_seconds"])  # total sandbox-seconds
print(usage["sandbox_count"])    # distinct sandboxes created
print(usage["cost_usd"])         # dollar amount for billing
```

```typescript
const usage = await client.usage.get({
  externalUserId: "user_42",
  periodStart: "2026-05-01T00:00:00Z",
  periodEnd: "2026-06-01T00:00:00Z",
});

console.log(usage.computeSeconds); // total sandbox-seconds
console.log(usage.sandboxCount);   // distinct sandboxes created
console.log(usage.costUsd);        // dollar amount for billing
```

### Per-user quotas

Prevent a single customer from consuming your entire compute budget. Set quotas at the workspace or project level, or enforce them in your own API layer:

```python
# List sandboxes for this user and reject if at the limit.
SANDBOX_LIMIT_PER_USER = 5

existing = client.sandboxes.list(external_user_id="user_42", state="running")
if len(existing) >= SANDBOX_LIMIT_PER_USER:
    return jsonify({"error": "sandbox limit reached"}), 429
```

```typescript
const SANDBOX_LIMIT_PER_USER = 5;

const existing = await client.sandboxes.list({
  externalUserId: "user_42",
  state: "running",
});
if (existing.length >= SANDBOX_LIMIT_PER_USER) {
  return res.status(429).json({ error: "sandbox limit reached" });
}
```

### Teardown on cancellation

Destroy all sandboxes when a customer cancels their account:

```python
sandboxes = client.sandboxes.list(external_user_id="user_42")
for sandbox in sandboxes:
    client.sandboxes.delete(sandbox["id"])
    print(f"Destroyed {sandbox['id']}")
```

```typescript
const sandboxes = await client.sandboxes.list({ externalUserId: "user_42" });
for (const sandbox of sandboxes) {
  await client.sandboxes.delete(sandbox.id);
  console.log(`Destroyed ${sandbox.id}`);
}
```

## End-user UI components

Give your users a native feel with file browsing, terminal, and run-button components backed by the MIOSA SDK. All three require a browser token with the appropriate scopes (see [Preview permission scoping](/docs/develop/previews/#permission-scoping)).

### File tree

```typescript

const client = new Miosa({ apiKey: browserToken }); // mp_ token from your backend

async function loadFileTree(sandboxId: string, path = "/workspace") {
  const entries = await client.files.list(sandboxId, path);
  return entries.map((e) => ({
    name: e.name,
    type: e.type,   // "file" | "directory"
    path: e.path,
    size: e.size,
  }));
}
```

### Terminal

```typescript
// Stream terminal output as an async iterable.
const stream = client.exec.stream(sandboxId, "bash", {
  cols: 80,
  rows: 24,
});

for await (const chunk of stream) {
  terminalEmulator.write(chunk.data);
}
```

### Run button

```typescript
// One-shot exec with streaming output.
const result = await client.exec.run(sandboxId, "npm test", {
  workingDir: "/workspace",
  timeoutMs: 30_000,
});

console.log(result.stdout);
console.log(result.exitCode); // 0 = pass
```

## End-to-end checklist

- [ ] Set branding: `product_name`, `logo_url`, `support_email`
- [ ] Register preview domain and add DNS CNAMEs
- [ ] Verify DNS propagation
- [ ] Register webhook and store the secret in your environment
- [ ] Create sandboxes with `external_user_id`, `external_project_id`, and `metadata`
- [ ] Mint preview tokens server-side only  -  never expose `msk_*` to the browser
- [ ] Verify HMAC-SHA256 on every webhook delivery
- [ ] Reject stale webhook timestamps (>5 min)
- [ ] Deduplicate webhook events by `event.id`
- [ ] Query usage by `external_user_id` for billing
- [ ] Enforce per-user sandbox quotas before creating
- [ ] Destroy sandboxes on cancellation

# Pricing and limits

URL: https://miosa.ai/docs/pricing
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/pricing
Source: src/routes/docs/pricing/+page.md
Description: What a sandbox costs per hour, what a plan buys, how many sandboxes you can run and start, and how that compares to other providers.

# Pricing and limits

What a sandbox costs per hour, what a plan buys, how many sandboxes you can run and start, and how that compares to other providers.

Every size has one price per hour. You pay it per second, and only while a sandbox or computer is running.
A paused, stopped or destroyed sandbox costs nothing for compute, and the price does not change with how busy the machine is.
Storage is metered on its own: disk costs $0.09 per GiB-month while the machine runs, and paused disk, named snapshots, and backups cost $0.018 per GiB-month. Buckets and static sites cost $0.0162 per GiB-month.
One credit is always one US cent.
Each organization keeps 10 named snapshots included; each one after that is $1.70 a month.
There are no other discounts, bonuses or free allowances: egress is billed from the first GB. Builds are free.

## Price

| Size | Per hour | Always on (730 h) | CPU | RAM | Disk |
|---|---|---|---|---|---|
| `micro` | $0.0316 | $23.05 | 1 vCPU | 0.5 GiB | 10 GiB |
| `tiny` | $0.0359 | $26.22 | 1 vCPU | 1 GiB | 20 GiB |
| `xs` | $0.0446 | $32.58 | 1 vCPU | 2 GiB | 10 GiB |
| `small` | $0.0893 | $65.16 | 2 vCPU | 4 GiB | 10 GiB |
| `quad` | $0.1437 | $104.90 | 4 vCPU | 4 GiB | 20 GiB |
| `medium` | $0.1785 | $130.32 | 4 vCPU | 8 GiB | 20 GiB |
| `large` | $0.3570 | $260.65 | 8 vCPU | 16 GiB | 40 GiB |
| `xl` | $0.7141 | $521.29 | 16 vCPU | 32 GiB | 80 GiB |

- The price is the size: it is the same whether the machine is idle or fully busy, and it is charged per second while the machine runs.
- Disk is provisioned, not used: you pay for the disk the size allocates, whether or not it is filled, at the storage rates above.
- `small` is the default size.
- Every size is a full machine with the same features, templates, and API. Only the resources change.
- Computers (desktops) come in `xs` through `xl`. A computer costs $0.01512 per vCPU-hour and $0.00486 per GiB-hour, a little over half the price of a sandbox of the same size: `medium` $0.0994 an hour. Their disks are larger: `xs` 10 GiB, `small` 20 GiB, `medium` 40 GiB, `large` 80 GiB, `xl` 160 GiB.

Apps and databases are billed on what they use, and never more than the price of their size in this table.
A small app that sits idle most of the day pays far less than the table; a busy one pays the table price at most.
Egress is $0.054 per GB, with no free allowance.
Deployment builds are free.
Your plan sets the largest size you can pick, never the price.

## Apps, services and databases

Apps, services and databases are billed on what they use, per second, and never more than the price of their size.

| What | Price |
|---|---|
| CPU actually busy | $21.915 per vCPU-month |
| Memory actually used | $10.953 per GiB-month |
| Idle CPU, unused memory, a stopped service | not billed |
| Most you can pay for a size, per second while it runs | the size price in the table above (`xs` $0.0446 an hour, `small` $0.0893, `medium` $0.1785, `large` $0.3570, `xl` $0.7141) |

- A small app that sits idle most of the day pays far less than its size price; a busy one pays the size price at most. The size is the cap, not the bill.
- Managed databases follow the same rule on their own sizes (never more than the sandbox price of the same size), plus disk at $0.162 per GiB-month.
- Running disk is $0.09 per GiB-month and egress $0.054 per GB. Builds are free.
- `GET /api/v1/pricing` lists each size under `products.machines.app.sizes` and `products.machines.database.sizes` with `usd_per_hour` and `usd_per_month`, and `price_kind` `maximum`.

## Plans and concurrency

| Plan | Price | Included usage each month |
|---|---|---|
| Free | $0 | $1 |
| Developer | $20/mo | $20 |
| Business | $500/mo | $500 |
| Enterprise | $2,000/mo | $2,000 |

Limits per service and per account are on [Plans and limits](/docs/plans-and-limits).

- The plan price comes back as usage: Business is $500 for $500 of usage, and every credit spends at the prices above.
- Plans never change the price of a size, only the caps.
- Top up any time from $1 to $5,000. Purchased credits never expire; recurring plan credits expire a month after they are granted.
- Start free with $1 of usage every month. Paid plans pay as you go. Free stops at its $1 unless you buy credits. Add credits any time.
- When your balance reaches $0, running computers and sandboxes pause and resume on their own when you add credit; databases and deployments are stopped and may need a manual restart after you add credit. Nothing is deleted. New machines start only while you have credit.
- Starting a sandbox is an API call, so it is rate-limited per API key (60 to 30,000 requests per minute by tier) and per plan. See [Rate limits](/docs/rate-limits/).

## Limits

| Limit | Value |
|---|---|
| Concurrent sandboxes | See [Plans and limits](/docs/plans-and-limits) |
| Sandbox lifetime (`timeout_sec`) | 1 to 86,400 seconds, default 3,600 |
| Idle auto-pause | 30 minutes for accounts created on or after October 11, 2026; wakes on the next request |
| Exec | 30 seconds per call by default; detached jobs have no limit |
| Run code (`/code/run`) | 300 seconds maximum |
| File upload | 500 MB per write |
| Browser token | 1 hour by default, 60 seconds to 7 days |
| Named snapshots | 10 free per organization, then $1.70 a month each |

Cap one of your own end users, below the organization limit, with the [Quotas API](/docs/api-reference/quotas/) (`max_sandboxes`, `max_concurrent`, `max_storage_gb`, `max_credit_cents`).

## Compared to others

The same machine, **4 vCPU and 8 GiB of RAM, running**, at each provider's public list price, checked 2026-10-20.
Each price is followed by its multiplier against MIOSA.

| Provider | 4 vCPU + 8 GiB / hour | vs MIOSA |
|---|---|---|
| **MIOSA** | **$0.1785** | **1x** |
| Railway | $0.2223 | 1.2x |
| Freestyle | $0.2645 | 1.5x |
| E2B | $0.3312 | 1.9x |
| Vercel † | $0.6816 | 3.8x |

† Bills active CPU, not allocated CPU.

MIOSA's figure is compute only; disk is metered separately at the rate above.
Several providers meter storage and egress on top of compute, so a real monthly bill can differ from the compute line.

MIOSA is below every provider listed here for this machine.
For capabilities and measured performance, see [MIOSA vs other platforms](/docs/compare) and the [compute provider comparison](/docs/integrations/comparison/).

Sources, each checked 2026-10-20: [Freestyle](https://www.freestyle.sh/pricing), [E2B](https://e2b.dev/pricing), [Railway](https://railway.com/pricing), [Vercel Sandbox](https://vercel.com/docs/vercel-sandbox/pricing).

### Why some providers list a lower hourly price

Most sandbox providers sell the machine, and that is where their product ends.
You then stitch together other services for hosting, databases, agents, tenants and billing.

MIOSA prices the machine as part of a whole platform, so one account covers what you need to build and run a full-stack, multi-tenant application:

- [Deployments and Docker Host](/docs/docker-host/overview) to publish what you build to a stable URL with your own domain, versions and rollback.
- [Agents](/docs/guides/agent-operating-guide) with harnesses and approvals, running inside your machines.
- [Managed data](/docs/data/overview): Postgres, Redis, MySQL and Qdrant.
- [Organizations, workspaces and the white-label kit](/docs/platform/overview) to run it for your own team or sell it as your product.

If you only need a raw sandbox and nothing around it, a sandbox-only provider may fit.
If you want to build, deploy and run a product on one platform, that is where MIOSA's value is.

## Performance

MIOSA in the independent ComputeSDK benchmark suite. Every run is a committed JSON file, so each number can be checked against the repository.

| Benchmark | MIOSA | Field | Date |
|---|---|---|---|
| Burst startup: 100 concurrent creates, timed to the first command | 57.09 ms median | #1 of 32 | 2026-10-23 |
| DAX build: clone, install, typecheck in a fresh sandbox | 38.4 s | #1 of 16 completed | 2026-08-21 |
| DAX build, latest completed run | 39.2 s | #2 of 20 | 2026-10-02 |

See [Benchmarks](/docs/benchmarks/) for every run and the raw results.
A cost per run is not published, because the benchmark sandbox size is not part of the result; size a run from the rates in [Worked examples](#worked-examples).

## Worked examples

| You run | Per month |
|---|---|
| 1 `small` sandbox, 2 hours a day (60 h) | 60 x $0.0893 = **$5.36** |
| 1 `small` sandbox, always on (730 h) | 730 x $0.0893 = **$65.19** |
| 1 `medium` sandbox, 8 hours a day (176 h) | 176 x $0.1785 = **$31.42** |
| 1 `large` sandbox, always on (730 h) | 730 x $0.3570 = **$260.61** |
| 10,000 one-minute jobs on `small` | 166.7 h x $0.0893 = **$14.89** |
| 10 GiB kept paused for a month | 10 x $0.018 = **$0.18** |
| 10 GiB of disk on a running `small` sandbox, always on (730 h) | 10 x $0.09 = **$0.90**, on top of the $65.19 |

Compute for these examples only; running disk is metered on top at $0.09 per GiB-month.

## For the API

- `GET /api/v1/pricing` returns the price book this page is built from: for each product a list of sizes with `usd_per_hour` and `usd_per_month` (730 hours), the per-resource rates, and the plans. Sandboxes and computers have `price_kind: "flat"`; apps and databases have `price_kind: "maximum"`, the most they can cost for that size. `GET /api/v1/compute/pricing` serves the same body.
- `GET /api/v1/credits/balance` reports the balance in credits, with lifetime earned, lifetime spent, and the nearest expiry. One credit is $0.01, so 100 credits is $1.00.
- A sandbox or computer is billed the price of its size per second while it runs, with a 1-second minimum, and settled against the balance every 5 minutes. Apps and databases are billed on measured CPU and memory use, capped per second at the price of their size.
- The [Usage Rollup API](/docs/api-reference/usage-rollup/) aggregates by `external_user_id`, `external_project_id`, or `workspace_id`, so a rollup maps onto your own billing.

Every plan pays the same price for a size. Plans only change the caps and the concurrency, never the price.

## MIOSA AI pricing

MIOSA AI bills in wallet credits where 1 credit is 1 cent.
Each model has its own input and output price per 1M tokens, listed with real model names on the [pricing page](/pricing#ai-models) and under `ai.models` in `GET /api/v1/pricing`.
The default model, `kimi-k2.6`, is also reachable as `optimal`.
`deepseek-v4.1-flash` is the low-cost model and is also reachable as `optimal-fast`.
Every chat has the full context of its model, with automatic compaction when it fills.
See [Optimal](/docs/optimal/) for how chats work.

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/projects
Source: src/routes/docs/projects/+page.md
Description: Group the resources for one app, site, or deliverable inside a Workspace, without becoming a runtime.

# Projects

A **Project** is the durable product boundary inside one Workspace.
It groups the resources for one application, site, workflow, or customer deliverable, and it never runs code itself.
Every resource that belongs to the product carries the project's `project_id`, so ownership, deployment history, domains, members, and usage all roll up to one boundary.

A Project always belongs to exactly one Workspace, and a Workspace belongs to one Organization.
The Workspace is required: creating a Project with no workspace fails with `WORKSPACE_REQUIRED`.

## 1. Create a project

```bash
miosa project create "Lead Magnet" \
  --workspace-id "$MIOSA_WORKSPACE_ID" \
  --description "Customer lead capture app"

miosa project list
miosa project get lead-magnet
```

## 2. Add resources

```bash
# Create a sandbox in the workspace, then publish its output.
miosa create lead-magnet-dev --workspace acme-corp --wait
miosa deploy create --from-sandbox lead-magnet-dev --wait
```

## 3. Deploy

```bash
miosa deploy create --git https://github.com/me/lead-magnet --branch main --wait
```

Publishing creates an immutable version under the Deployment and prints the URL.
Display the URL the API returns; never rebuild it from a slug.

# Project lifecycle

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/projects/lifecycle
Source: src/routes/docs/projects/lifecycle/+page.md
Description: Create a project, add resources, configure environments and secrets, deploy, then retire it.

# Project lifecycle

The five steps below are the whole path: create, add resources, configure environments and secrets, deploy, then retire.

## 1. Create a project

```bash
miosa project create "Lead Magnet" \
  --workspace-id "$MIOSA_WORKSPACE_ID" \
  --description "Customer lead capture app"

miosa project list
miosa project get lead-magnet
```

```bash
curl -X POST https://api.miosa.ai/api/v1/projects \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_id": "'"$MIOSA_WORKSPACE_ID"'",
    "name": "Lead Magnet",
    "slug": "lead-magnet",
    "external_project_id": "project_789"
  }'
```

The response is `201` with the project record.
`workspace_slug` or `external_workspace_id` also resolve the workspace; `slug` is derived from `name` when you omit it.

## 2. Add resources

```bash
# Create a sandbox in the workspace, then publish its output.
miosa create lead-magnet-dev --workspace acme-corp --wait
miosa deploy create --from-sandbox lead-magnet-dev --wait
```

```ts

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY });

// Project CRUD is REST and CLI only; the SDK lists projects per workspace.
const projects = await miosa.workspaces.listProjects(workspaceId);
const project = projects.find((p) => p.slug === "lead-magnet");

const sandbox = await miosa.sandboxes.create({
  projectId: project.id as string,
  projectSlug: "lead-magnet",
});
```

```python
from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

projects = client.workspaces.list_projects(workspace_id)
project = next(p for p in projects if p["slug"] == "lead-magnet")

sandbox = client.sandboxes.create(
    project_id=project["id"],
    project_slug="lead-magnet",
)
```

```bash
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "project_id": "'"$PROJECT_ID"'", "name": "lead-magnet-dev" }'
```

Sandboxes, computers, deployments, databases, storage, functions, jobs, and domains all accept `project_id`.
When you only have your own identifier, pass `external_project_id` and MIOSA resolves or creates the project for you.
Machine commands in the CLI take `--workspace`, not a project, so the project resolves from the workspace default; use the API or an SDK when a resource must land in a named project.

## 3. Environments and secrets

Runtime environment variables resolve narrowest-wins:

```text
tenant defaults < workspace defaults < project defaults < resource env < request env
```

A project-scoped variable reaches every resource in the project without copying values into each one.

```bash
# CLI environments belong to a workspace or the organization.
echo "$STRIPE_SECRET_KEY" | miosa env set --env staging STRIPE_KEY
```

```ts
await miosa.runtimeEnv.set({
  scope: "project",
  projectId: project.id as string,
  name: "STRIPE_SECRET_KEY",
  value: process.env.STRIPE_SECRET_KEY!,
});
```

```python
client.runtime_env.set(
    scope="project",
    project_id=project["id"],
    name="STRIPE_SECRET_KEY",
    value=os.environ["STRIPE_SECRET_KEY"],
)
```

```bash
curl -X POST https://api.miosa.ai/api/v1/runtime-env \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "scope": "project",
    "project_id": "'"$PROJECT_ID"'",
    "target": "all",
    "name": "STRIPE_SECRET_KEY",
    "value": "sk_live_..."
  }'
```

Values are encrypted at rest and never returned in plaintext.
Production configuration for a single deployment is separate: a Deployment owns its own environments (`production`, `staging`, `preview`, `development`) with their own config.

## 4. Deploy

```bash
miosa deploy create --git https://github.com/me/lead-magnet --branch main --wait
```

```ts
// The sandbox already carries the project, so its deployment inherits it.
const deployment = await sandbox.deploy({ name: "lead-magnet" });
```

```python
# The sandbox already carries the project, so its deployment inherits it.
deployment = sandbox.deploy(name="lead-magnet")
```

```bash
# Create the deployment inside the project, then publish a version.
curl -X POST https://api.miosa.ai/api/v1/deployments \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "name": "lead-magnet", "project_id": "'"$PROJECT_ID"'", "repo_url": "https://github.com/me/lead-magnet", "branch": "main" }'

curl -X POST https://api.miosa.ai/api/v1/deployments/"$DEPLOYMENT_ID"/publish \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Publishing creates an immutable version under the Deployment and prints the URL.
Display the URL the API returns; never rebuild it from a slug.

## 5. Archive or delete

A project row has no state, so there is no project archive.
Archive is a resource concept: a Product is `active` or `archived`, and a deployment environment is `active`, `inactive`, or `archived`.
To retire a project, move or delete its resources first, then delete the project.

```bash
# The CLI creates, lists, and shows projects.
# Moving and deleting a project are REST operations.
miosa project list
miosa project get lead-magnet
```

```bash
# Move the project and its children to another workspace.
curl -X POST https://api.miosa.ai/api/v1/projects/"$PROJECT_ID"/move \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "target_workspace_id": "'"$TARGET_WORKSPACE_ID"'" }'

# Delete the project once it owns nothing.
curl -X DELETE https://api.miosa.ai/api/v1/projects/"$PROJECT_ID" \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Delete returns `204`.
It returns `409 PROJECT_HAS_RESOURCES` with a `details.impact` document listing what still blocks the delete, and `409 DEFAULT_PROJECT_PROTECTED` for a workspace's Default project.
Move is refused for the Default project and for a caller who is not a workspace admin.

# Members and usage

Access follows the hierarchy and narrows at the project:

- Every Workspace member inherits access to every project in that workspace.
- A **project member** row narrows one user's role for one project. Roles are `owner`, `admin`, `developer`, and `viewer`, and the user must already belong to the parent workspace.
- Project endpoints are gated by the `projects:read` and `projects:write` scopes. An API key bound to a workspace pins `workspace_id` for you, so you do not repeat it in the body.
- Member management lives at `GET` and `POST /api/v1/projects/{id}/members` and `PATCH` and `DELETE /api/v1/projects/{id}/members/{user_id}`.

Usage is attributed by the `project_id` on every metered row.
The project roll-up is available at `GET /api/v1/projects/{id}/usage`, and `GET /api/v1/usage/projects` groups settled cost and runtime hours by project or by workspace.
Usage that carries no project is reported in an explicit `unattributed` bucket rather than merged into a named project, so a total that is short is visibly short.
Your `external_project_id` flows through to usage, audit, and list filters.

## Operating checklist

- Every resource resolves to exactly one Organization and Workspace.
- Every product resource has the intended `project_id`.
- Development happens in a Sandbox, not the live Deployment.
- Production changes only through publish, verify, and promote.
- Data survives Sandbox replacement and application rollback.
- The UI displays the authoritative URL returned by the API.
- The project is not the Default project if you plan to delete or move it.

## Common mistakes

| Symptom | Likely cause | Correction |
|---|---|---|
| Resources appear under the wrong customer | Workspace or Project was inferred from stale UI state | Send the canonical IDs explicitly |
| A new app overwrites an older app's history | Both products share one Project and Deployment | Create a separate Project and Deployment |
| A domain change does not affect Sandbox previews | A production hostname was changed | Configure the Project preview domain separately |
| Deleting a Sandbox appears to delete the app | Development and production were treated as one resource | Publish to a Deployment before removing development state |
| A delete returns `409 PROJECT_HAS_RESOURCES` | Sandboxes, deployments, or data still carry the `project_id` | Move or delete the listed resources first, then delete |
| A delete or move returns `409 DEFAULT_PROJECT_PROTECTED` | The target is the workspace's Default project | Create a named project and move the resources into it |

Description: The project record, everything that attaches to a project, and how a project maps to your own platform.

# Project resources

The project record itself holds only identity and attribution:

| Field | Purpose |
|---|---|
| `id` | Canonical UUID. Store this after the first resolution. |
| `tenant_id` | The Organization that owns the project. |
| `workspace_id` | The Workspace the project lives in. Required. |
| `name` | Display name, 1 to 120 characters. |
| `slug` | URL-safe key, 1 to 80 characters, unique per workspace. Derived from the name when omitted. |
| `description` | Optional free text. |
| `metadata` | Arbitrary key-value map. |
| `is_default` | True for the workspace's Default project. A client cannot set this. |
| `external_project_id` | Your own project id, unique per Organization. Attribution only. |
| `external_workspace_id` | Your own workspace id, inherited from the Workspace. Attribution only. |

## Where a project fits

Diagram:
flowchart TD
  O["Organization<br/>billing, plan, policy"] --> W["Workspace<br/>team, customer, or business boundary"]
  W --> P["Project<br/>one app or deliverable"]
  P --> S["Sandboxes"]
  P --> C["Computers"]
  P --> D["Deployments"]
  P --> DATA["Data services"]
  P --> DOM["Domains"]
  D --> V["Versions and releases"]

A Sandbox, Computer, or Runtime Instance executes work.
A Project provides ownership and organization around those resources.

Every Workspace also has one **Default project**, created on demand and marked `is_default`.
It is the home for resources created without an explicit project, and it can neither be deleted nor moved.

## What lives in a project

Resources attach to a project through a canonical `project_id` column, and most also carry `workspace_id` and your `external_project_id`.
A resource create call can resolve the project for you: pass `project_id`, `project_slug`, `project_name`, or `external_project_id` and MIOSA resolves or creates the project before inserting the resource.

| Resource | In a project | Notes |
|---|---|---|
| Sandbox | Yes | The mutable development environment. Carries `project_id` and `workspace_id`. |
| Sandbox preview | Yes | Generated preview URL for a sandbox. |
| Computer | Yes | The desktop runtime. Carries `project_id`; computers have no `workspace_id` column. |
| Deployment | Yes | Durable production identity. It owns versions, releases, services, environments, builds, runtime instances, and preview environments, and every one of those children carries the same `project_id`. |
| Managed database | Yes | Project-scoped with no workspace column. One is auto-provisioned when the project is created. |
| Database | Yes | Database attached to a sandbox. |
| Managed service | Yes | Project-scoped with no workspace column. |
| Storage bucket | Yes | S3-compatible object storage. |
| Volume | Yes | Durable filesystem. A `/data` volume is auto-created with the project. |
| Custom domain | Yes | An exact hostname attached to a sandbox, computer, or deployment. |
| Edge function | Yes | Code that runs at the edge. |
| Cron job | Yes | Scheduled executions. |
| Workflow | Yes | Carries `project_id` with no workspace column. |
| Project auth | Yes | Built-in auth for one sandbox or deployment, with an encrypted JWT secret. |
| Project integration | Yes | Provider credentials such as Stripe, Resend, and Twilio. |
| Runtime env var | Yes | `scope` is `tenant`, `workspace`, or `project`. Values are encrypted at rest. |
| Agent definition and runtime profile | Yes | Agent configuration scoped to the project. |
| Usage meter | Yes | The billing dimension a resource is metered under. |
| Run | Yes | Detached when the project is deleted: `project_id` is set to null, the run is not deleted. |
| Project member | Yes | Cascades on project delete. |
| Product link | Yes | A Product groups one or more projects inside a workspace. |
| Audit, usage, and platform events | Attribution only | Immutable history. It keeps the project it was recorded under and is never rewritten. |
| Workspace | No | The parent boundary. A project has exactly one. |
| Organization | No | Two levels above the project. It owns billing and policy. |

For the live counts, health roll-up, last deploy, and linked repository of one project, call `GET /api/v1/projects/{id}/summary`.

## Project, workspace, or organization?

| Need | Use |
|---|---|
| Separate company billing and policy | Organization |
| Separate team, customer, or business boundary | Workspace |
| Group one app and its resources | Project |
| Develop mutable source | Sandbox |
| Operate one stable production app | Deployment |
| Keep a persistent interactive desktop | Computer |

Create separate Projects when applications need independent deployment history, domains, environments, or usage attribution.

Do not create a new Project for every build, preview, or release.
Previews and releases belong to the Deployment inside the project, not to a new project.

## Domains

Preview domains are an organization-level setting, not a per-project one.
A tenant preview domain white-labels generated preview links for the whole organization; an exact custom hostname attaches to one Deployment or Computer.

The effective order is:

```text
Exact deployment/computer hostname
  -> Organization preview domain
  -> MIOSA-managed fallback
```

Always display URLs returned by MIOSA instead of rebuilding them from slugs.

Every custom domain row carries `project_id` and `workspace_id` alongside the resource it points at, so a hostname is scoped and attributed the same way the resource is.

## Mapping your own platform onto projects

| Your platform | MIOSA |
|---|---|
| Company account | Organization |
| Customer or team | Workspace |
| App, site, document, or product | Project |
| Editable build environment | Sandbox |
| Live application | Deployment |

Three worked examples:

| Platform | Shape | Why |
|---|---|---|
| Lumen | One Project per customer app, inside one Workspace | Each app gets its own deployment history, domains, and usage line while the whole platform stays on one billing account. |
| Acme Corp | One Project per internal tool, inside one Workspace per department | Tools share the company's Organization and policy but roll up their usage and members separately. |
| Northwind Agency | One Workspace per client, one Project per deliverable | The client boundary is the Workspace, so isolating clients never leaks into a per-deliverable project. |

Store the canonical `workspace_id` and `project_id` after the first resolution.
Use `external_workspace_id`, `external_project_id`, and `external_user_id` for correlation, not as substitutes for MIOSA ownership.

# Quickstart

URL: https://miosa.ai/docs/quickstart
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/quickstart
Source: src/routes/docs/quickstart/+page.md
Description: Install the CLI, start a sandbox, let an agent build something inside it, and open it at a live URL.

# Quickstart

MIOSA runs isolated Linux sandboxes and full cloud desktops for your code and your AI agents, then publishes the result to a live URL.
This page takes you from install to an app that an agent built, in four steps.

## Let your agent drive MIOSA

Most people run MIOSA through a coding agent, not by hand.
Your agent can run on your laptop and control the whole platform.
It has four ways in:

| Way in | What to do |
|---|---|
| CLI | Your agent runs `miosa` commands. Start it with the [Agent operating guide](/docs/guides/agent-operating-guide/). |
| MCP server | `miosa mcp install --client claude` (also `cursor` and `gemini`). OSA and Hermes use a config file instead: see [MCP](/docs/mcp/). |
| Skills | Claude Code skills for sandboxes, computers, and deploys. See [Claude Code skills](/docs/guides/skills/). |
| `llms.txt` | Point any agent at [miosa.ai/llms.txt](https://miosa.ai/llms.txt). It lists every docs page in plain text. |

This works with OSA, Claude Code, Codex, OpenCode, Hermes, Kimi Code, and more.
The rest of this page puts an agent inside a sandbox.

Already know what you need?

- [Sandbox to deployment](/docs/quickstart/sandbox-to-deployment/): the recommended first walkthrough.
- [Agent-driven build](/docs/quickstart/agent-driven-build/): dispatch work, stream events, and collect artifacts from your backend.
- [Docker Host](/docs/quickstart/app-engine/): run containerized applications on a workspace Docker Host host; check [availability](/docs/availability/) first.
- [Connect your own server](/docs/opencomputers/connect/): run your first command on a Linux machine you operate.

## 1. Install

```bash
curl -fsSL https://raw.githubusercontent.com/Miosa-osa/miosa-cli-go/main/install.sh | sh
```

```powershell
npm i -g @miosa/cli
```

The installer does these steps:

1. Detects your OS and CPU.
2. Downloads the matching `miosa` binary and checks its SHA-256.
3. Installs it to `~/.local/bin/miosa` (or `/usr/local/bin` when run as root).

Then run `miosa login` to sign in: it opens your browser, and the key for this machine is stored in `~/.miosa/config.toml`.
Prefer npm, Homebrew, or a manual download? See [Install the CLI or SDK](/docs/cli/install/).

## 2. Start a sandbox

```bash
miosa create my-box --wait     # provision a sandbox and wait until it is ready
miosa list                     # see all your sandboxes
```

A sandbox is a fast, isolated Linux VM.
Your agent writes files into it, runs commands, and opens ports as live preview URLs.
Its filesystem persists when the sandbox pauses, so you can resume it later.
Read [Sandboxes](/docs/develop/sandboxes/) for sizes, limits, and lifecycle.

## 3. Run an agent inside it

Pick your agent.
MIOSA installs it in the sandbox and runs it there.
The agent uses your own model account, so you pay your own provider.
MIOSA credits never pay for the model.

Each agent has three parts: connect your account, start the agent, and give it a task.

OSA is MIOSA's own agent. It works with the model you connect.

**Connect.**
Open the MIOSA console, go to **Agents**, and connect your model key for OSA.

**Start it and give it a task.**

```bash
miosa prompt --harness osa --sandbox my-box \
  "Build a landing page and serve it on port 3000"
```

**Connect.**
Sign in with your Claude plan.
The command prints a link and a code. Approve it in your browser, then paste the code back.

```bash
miosa connections add models claude --sandbox my-box
```

Or use your own Anthropic key:

```bash
miosa connections add models anthropic --key-stdin <<< "$ANTHROPIC_API_KEY"
```

**Start it and give it a task.**

```bash
miosa prompt --harness claude-code --sandbox my-box \
  "Build a landing page and serve it on port 3000"
```

**Connect.**
Sign in with your ChatGPT plan.
The command prints a link and a code. Approve it in your browser.

```bash
miosa connections add models chatgpt --sandbox my-box
```

Or use your own OpenAI key:

```bash
miosa connections add models openai --key-stdin <<< "$OPENAI_API_KEY"
```

**Start it and give it a task.**

```bash
miosa prompt --harness codex --sandbox my-box \
  "Build a landing page and serve it on port 3000"
```

**Connect.**
In the MIOSA console, go to **Agents** and connect one of these for OpenCode: an Anthropic, OpenAI, OpenRouter, or Mistral key, or your ChatGPT plan.
`miosa connections` does not cover this agent yet.

**Start it and give it a task.**

```bash
SANDBOX_ID=$(miosa info my-box --json | jq -r .id)
RUN=$(miosa api POST /runs -d "{
  \"runner\": \"opencode\",
  \"sandbox_id\": \"$SANDBOX_ID\",
  \"instruction\": \"Build a landing page and serve it on port 3000\"
}" | jq -r .data.id)
miosa run follow $RUN
```

Hermes Agent is a first-class runner in the run API.
It is not in the CLI `--harness` list yet, so start it with the run API.

**Connect.**
In the MIOSA console, go to **Agents**, and connect a ChatGPT plan, a Claude plan (Max with extra usage), or an Anthropic, OpenAI, or OpenRouter key.
`miosa connections` does not cover this agent yet.

**Start it and give it a task.**

```bash
SANDBOX_ID=$(miosa info my-box --json | jq -r .id)
RUN=$(miosa api POST /runs -d "{
  \"runner\": \"hermes\",
  \"sandbox_id\": \"$SANDBOX_ID\",
  \"instruction\": \"Build a landing page and serve it on port 3000\"
}" | jq -r .data.id)
miosa run follow $RUN
```

**Connect.**
In the MIOSA console, go to **Agents** and connect your Kimi Code plan or your Moonshot key.
`miosa connections` does not cover this agent yet.

**Start it and give it a task.**

```bash
SANDBOX_ID=$(miosa info my-box --json | jq -r .id)
RUN=$(miosa api POST /runs -d "{
  \"runner\": \"kimi\",
  \"sandbox_id\": \"$SANDBOX_ID\",
  \"instruction\": \"Build a landing page and serve it on port 3000\"
}" | jq -r .data.id)
miosa run follow $RUN
```

**Connect.**
In the MIOSA console, go to **Agents** and connect one of these for Pi: an Anthropic, OpenAI, OpenRouter, or Mistral key, or your Claude or ChatGPT plan.
`miosa connections` does not cover this agent yet.

**Start it and give it a task.**

```bash
SANDBOX_ID=$(miosa info my-box --json | jq -r .id)
RUN=$(miosa api POST /runs -d "{
  \"runner\": \"pi\",
  \"sandbox_id\": \"$SANDBOX_ID\",
  \"instruction\": \"Build a landing page and serve it on port 3000\"
}" | jq -r .data.id)
miosa run follow $RUN
```

**Connect.**
In the MIOSA console, go to **Agents** and connect your Mistral Vibe plan or your Mistral key.
`miosa connections` does not cover this agent yet.

**Start it and give it a task.**

```bash
SANDBOX_ID=$(miosa info my-box --json | jq -r .id)
RUN=$(miosa api POST /runs -d "{
  \"runner\": \"mistral\",
  \"sandbox_id\": \"$SANDBOX_ID\",
  \"instruction\": \"Build a landing page and serve it on port 3000\"
}" | jq -r .data.id)
miosa run follow $RUN
```

If you have not connected an account, the run is refused or fails.
MIOSA never falls back to its own keys.

## 4. See what it built

```bash
miosa preview create my-box 3000 --visibility public
```

Open the URL it prints.
That is the page your agent built, served from inside the sandbox.

If nothing loads, the agent did not leave a server running.
Start one yourself:

```bash
miosa process start my-box --name web --cwd /workspace -- python3 -m http.server 3000 --bind 0.0.0.0
```

## Or do it by hand

You do not need an agent for this.
Write a file, start a server, and open a preview yourself.

```bash
miosa exec my-box -- echo "hello from MIOSA"
echo "<h1>Hello</h1>" | miosa files write my-box:/workspace/index.html
miosa process start my-box --name web --cwd /workspace -- python3 -m http.server 3000 --bind 0.0.0.0
miosa preview create my-box 3000 --visibility public
```

`miosa process start` returns at once and keeps the server running.
Do not use `miosa exec` for a server, because `exec` waits for the command to end.

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceSlug: "default", // the workspace it belongs to; every create names one
  wait: true, // hold the call until the sandbox is ready
})
console.log(sandbox.id, sandbox.state)
// sbx_a1b2c3d4e5  running

await sandbox.files.write(
  "/workspace/index.html",
  `<!doctype html>
<html lang="en">
  <head><meta charset="utf-8"><title>My App</title></head>
  <body><h1>Hello from MIOSA</h1><p>Built in a sandbox.</p></body>
</html>`
)

// Start the server in the background. This call returns right away.
await sandbox.exec(
  "nohup python3 -m http.server 3000 --bind 0.0.0.0 > /tmp/web.log 2>&1 &",
  { cwd: "/workspace" }
)

const preview = await sandbox.previews.create(3000)
console.log(preview.url)
// https://3000-abc12345.sandbox.miosa.ai
```

You can also hand the whole job to an agent: `await sandbox.run("Build a landing page and serve it on port 3000", { runner: "codex" })`.

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sandbox = miosa.sandboxes.create(
    template_id="miosa-sandbox",
    workspace_slug="default",  # the workspace it belongs to; every create names one
    wait=True,
)
print(sandbox.id, sandbox.state)
# sbx_a1b2c3d4e5  running

sandbox.files.write(
    "/workspace/index.html",
    """<!doctype html>
<html lang="en">
  <head><meta charset="utf-8"><title>My App</title></head>
  <body><h1>Hello from MIOSA</h1><p>Built in a sandbox.</p></body>
</html>""",
)

# Start the server in the background. This call returns right away.
sandbox.processes.start("python3 -m http.server 3000 --bind 0.0.0.0", name="web")

preview = sandbox.previews.create(port=3000)
print(preview["url"])
# https://3000-abc12345.sandbox.miosa.ai
```

Open the preview URL MIOSA returns. Your `index.html` is served live from inside the sandbox.

# Agent-driven build

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/quickstart/agent-driven-build
Source: src/routes/docs/quickstart/agent-driven-build/+page.md
Description: Dispatch work to your agent, stream events, and collect artifacts from your backend, tagging every resource with your own customer IDs.

# Agent-driven build

This track treats the sandbox as an agent's tool environment.
You can supply the intelligence from your own backend, or use the Agent Runs API when you want MIOSA to dispatch OSA, Claude Code, Codex, or another harness against a sandbox or computer target.

For the managed runner path, see [Agent Runs](/docs/api-reference/agent-runs/) and [Agent Run Groups](/docs/api-reference/agent-run-groups/).
To try a harness from the terminal first, follow [Quickstart, step 3](/docs/quickstart/#3-run-an-agent-inside-it).

## Pick a harness

A harness is the coding agent that MIOSA runs inside the sandbox.
You pick it with the `runner` field.
The agent uses your own model account, never MIOSA credits.

| Agent | `runner` | Connect your account |
|---|---|---|
| OSA | `osa` | Connect your model key in the console, under **Agents**. |
| Claude Code | `claude-code` | `miosa connections add models claude` (your plan) or `anthropic` (your key). |
| Codex | `codex` | `miosa connections add models chatgpt` (your plan) or `openai` (your key). |
| OpenCode | `opencode` | `miosa connections add models chatgpt`, `openrouter` or `anthropic`, then `miosa connections use opencode --all`. |
| Kimi Code | `kimi` | `miosa connections add models kimi` (your plan). |
| Pi | `pi` | `miosa connections add models anthropic`, `chatgpt` or `openrouter`, then `miosa connections use pi --all`. |
| Mistral | `mistral` | `miosa connections add models vibe` (your plan) or `mistral` (your key). |
| Hermes | `hermes` | `miosa connections add models chatgpt` (your plan) or `anthropic` / `openai` / `openrouter` (your key). |

Run one from your backend:

```typescript
const run = await sandbox.run("Build a landing page and serve it on port 3000", {
  runner: "osa", // or "claude-code", "codex", "opencode", "kimi", "pi", "mistral"
})
console.log(run.status)
```

```python
run = sandbox.run_agent(
    "Build a landing page and serve it on port 3000",
    runner="osa",  # or "claude-code", "codex", "opencode", "kimi", "pi", "mistral"
)
print(run["status"])
```

If the account for that harness is not connected, MIOSA refuses the run and says what to connect.

You do not need the console to connect one.
Set a key or connect a Claude or ChatGPT plan from your own code, for your workspace or for each of your end users: [Connect agent accounts](/docs/guides/connect-agent-accounts/).

```typescript
await miosa.connections.setKey({ provider: "anthropic", key: process.env.ANTHROPIC_API_KEY! })

// A customer's own Claude plan, used only for runs on their machines
const signin = await miosa.connections.connectSubscription({ provider: "claude", externalUserId: "user-456" })
console.log(signin.verificationUrl) // show it in your UI, then: await signin.submitCode(pastedCode)
```

```python
miosa.connections.set_key("anthropic", key=os.environ["ANTHROPIC_API_KEY"])

# A customer's own Claude plan, used only for runs on their machines
signin = miosa.connections.connect_subscription("claude", external_user_id="user-456")
print(signin.verification_url)  # show it in your UI, then: signin.submit_code(pasted_code)
```

### Step 1  -  Create a sandbox with external attribution.
   If you're embedding MIOSA in your own product, pass your user/project IDs so you can filter resources later.

```typescript
const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceSlug: "default", // the MIOSA workspace it belongs to
  wait: true, // hold the call until the sandbox is ready
  externalWorkspaceId: "acct-123", // your own grouping id, not a MIOSA workspace
  externalUserId: "user-456",
  externalProjectId: "intake-portal-789",
})
console.log(sandbox.id)
// sbx_f6g7h8i9j0
```

```python
sandbox = miosa.sandboxes.create(
    template_id="miosa-sandbox",
    wait=True,  # hold the call until the sandbox is ready
    external_workspace_id="acct-123",
    external_user_id="user-456",
    external_project_id="intake-portal-789",
)
print(sandbox.id)
# sbx_f6g7h8i9j0
```

### Step 2  -  Give your agent an exec tool.
   The pattern below shows the structure. Substitute `callYourLLM` with your actual model call.

```typescript
// Tool the agent can call
async function execInSandbox(command: string): Promise<string> {
  const result = await sandbox.exec(command)
  return result.stdout + result.stderr
}

// Example: agent scaffolds a project
const output = await execInSandbox("npx create-react-app /workspace/my-app --template minimal 2>&1 | tail -5")
console.log(output)
// Success! Created /workspace/my-app
// Happy hacking!
```

```python
def exec_in_sandbox(command: str) -> str:
    result = sandbox.exec(command)
    return result.stdout + result.stderr

# Example: agent scaffolds a project
output = exec_in_sandbox(
    "npx create-react-app /workspace/my-app --template minimal 2>&1 | tail -5"
)
print(output)
# Success! Created /workspace/my-app
# Happy hacking!
```

### Step 3  -  Let the agent write files directly.

```typescript
// Agent writes a component
await sandbox.files.write(
  "/workspace/my-app/src/App.jsx",
  `export default function App() {
  return <main><h1>Generated by my agent</h1></main>;
}`
)
```

```python
# Agent writes a component
sandbox.files.write(
    "/workspace/my-app/src/App.jsx",
    """export default function App() {
  return <main><h1>Generated by my agent</h1></main>;
}""",
)
```

### Step 4  -  Start the dev server, create a preview, stream it to your user.

```typescript
// Start the dev server in the background. This call returns right away.
await sandbox.exec("nohup npm start > /tmp/app.log 2>&1 &", { cwd: "/workspace/my-app" })

const preview = await sandbox.previews.create(3000)
const share = await sandbox.previews.share(preview.id as string)

console.log("embed this URL in your product's UI:", share.share_url)
// https://3000-abc12345.sandbox.miosa.ai?preview_token=miosa_pv_...
```

```python
# Start the dev server in the background. This call returns right away.
sandbox.processes.start("cd /workspace/my-app && npm start", name="app")

preview = sandbox.previews.create(port=3000)
share = sandbox.previews.share(preview["id"])

print("embed this URL in your product's UI:", share["share_url"])
# https://3000-abc12345.sandbox.miosa.ai?preview_token=miosa_pv_...
```

   The `share_url` is safe to put in an `&lt;iframe&gt;` in your end user's browser. It expires after the configured TTL. Your `msk_*` key never leaves your server.

### Step 5  -  Take a screenshot of a Computer (optional).
   If your agent needs to verify GUI output or run browser-based tasks, use a Computer instead of (or alongside) a Sandbox.

```typescript
const computer = await miosa.computers.create({
  name: "agent-desktop",
  template_type: "miosa-desktop",
  size: "small",
})

// Let the agent observe the screen
const png = await computer.desktop.screenshot()
// → Buffer containing PNG bytes; send to your vision model

// Let the agent interact
await computer.desktop.click({ x: 800, y: 400 })
await computer.desktop.type("hello world")

await computer.destroy()
```

```python
computer = miosa.computers.create(
    name="agent-desktop",
    template_type="miosa-desktop",
    size="small",
)

# Let the agent observe the screen
png = computer.desktop.screenshot()
# → bytes containing PNG; send to your vision model

# Let the agent interact
computer.desktop.click(x=800, y=400)
computer.desktop.type("hello world")

computer.destroy()
```

### Step 6  -  Publish what the agent built.

```typescript
const result = await sandbox.deploy({
  name: "intake-portal",
  outputPath: "/workspace/my-app/build",
})
// Read the production URL from the response; do not construct it.
console.log(result)
```

```python
result = sandbox.deploy(
    name="intake-portal",
    output_path="/workspace/my-app/build",
)
# Read the production URL from the response; do not construct it.
print(result)
```

### Step 7  -  Filter all sandboxes for this customer.

```typescript
const allForCustomer = await miosa.sandboxes.list({
  externalWorkspaceId: "acct-123",
})
console.log(`${allForCustomer.length} sandboxes for acct-123`)
// 3 sandboxes for acct-123
```

```python
all_for_customer = miosa.sandboxes.list(external_workspace_id="acct-123")
print(f"{len(all_for_customer)} sandboxes for acct-123")
# 3 sandboxes for acct-123
```

### Step 8  -  Clean up.

```typescript
await sandbox.destroy()
```

```python
sandbox.destroy()
```

### What you just did

| Step | What happened |
|------|--------------|
| External attribution | Tagged every resource with your customer's IDs  -  no MIOSA accounts needed for your end users |
| Exec as agent tool | Ran arbitrary shell commands inside an isolated VM from your agent loop |
| `files.write` | Agent wrote generated code directly to the sandbox file system |
| Share token | Minted a browser-safe URL for preview embedding  -  workspace key stays server-side |
| Computer screenshot | Optionally gave the agent a real desktop with a vision-accessible screen |
| `sandbox.deploy` | Shipped the agent's output to a permanent immutable URL |
| `sandboxes.list` with attribution | Queried only resources belonging to one customer  -  cross-tenant leakage impossible |

# Docker Host

URL: https://miosa.ai/docs/quickstart/app-engine
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/quickstart/app-engine
Source: src/routes/docs/quickstart/app-engine/+page.md
Description: Run containerized applications on a workspace Docker Host host, then confirm the app is live.

# Docker Host

Use Docker Host when a workspace needs many always-on apps, funnels, APIs, or client sites without provisioning a separate production VM for each deployment.
The visible product name is Docker Host.
The CLI and API still use `docker_deploy` as the internal compatibility value.

## Step 1  -  Ensure the workspace Docker Host host.

```bash
miosa api POST /docker-deploy/hosts/ensure -d '{"workspace_id": "<workspace-id>"}'
miosa api GET /docker-deploy/hosts
```

The host must be active before an Docker Host publish can finish.

## Step 2  -  Publish the sandbox to Docker Host.

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --run-command "npm run start" \
  --port 3000 \
  --type docker_deploy \
  --wait \
  --wait-timeout 900s \
  --json
```

The response includes the Deployment and its `public_url`.
That URL may be a MIOSA-managed tenant URL, a workspace deployment domain, a tenant deployment domain, or an exact custom domain.
Always show the returned URL.

## Step 3  -  Confirm the app is live.

```bash
miosa deploy get <deployment-id> --json
miosa deploy requests <deployment-id>
```

`deploy get` shows the deployment's status, product and `public_url`.
`deploy requests` shows the recent HTTP requests served, so you can confirm real traffic reaches the app.

## What you just did

| Step | What happened |
|------|--------------|
| `docker-deploy ensure` | Created or returned the workspace Docker Host host |
| `sandbox publish --docker-deploy` | Published the sandbox artifact as a container on that workspace host |
| `docker-deploy doctor` | Proved the container and public URL are real |

See [Docker Host](/docs/docker-host/docker-deploy/) for the full deployment contract, and [Deploy overview](/docs/docker-host/overview/) for the rest of the deploy surface.

# Sandbox to deployment

URL: https://miosa.ai/docs/quickstart/sandbox-to-deployment
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/quickstart/sandbox-to-deployment
Source: src/routes/docs/quickstart/sandbox-to-deployment/+page.md
Description: The full first walkthrough: create a sandbox, write code, preview it live, publish to production, and prove the deployment is running.

# Sandbox to deployment

Start with **Track 1: Sandbox to deployment**.
The recommended first walkthrough.
Your first success is a small site running at the production URL returned by MIOSA, with its deployment verified.
Complete that path before adding agent orchestration or another runtime.

> **Building a white-label product?** If your goal is to ship a SaaS where your customers never see the MIOSA brand, start with the [White-Label Integrator Guide](/docs/integrations) instead. It covers per-user provisioning, custom domains, iframe embeds, webhooks, and usage billing from scratch.

## Prerequisites

### Account and workspace

Create a MIOSA account at [miosa.ai](https://miosa.ai) and a workspace.

### API key

Create a key in Settings → API Keys for the intended workspace.
See [API keys](/docs/platform/api-keys/) for key types and scopes.
Export your key in the terminal where you will run the examples:

```bash
export MIOSA_API_KEY="msk_u_..."
```

### Install tooling for your language

```bash
npm install @miosa/cli @miosa/sdk
# or: pnpm add @miosa/cli @miosa/sdk
```

```bash
pip install --upgrade miosa
```

```elixir
# mix.exs  -  published on Hex.pm: https://hex.pm/packages/miosa
{:miosa, "~> 1.1"}
```

Then run `mix deps.get`.

**Zero-install option  -  just a URL + API key:**

```json
{
  "mcpServers": {
    "miosa": {
      "url": "https://api.miosa.ai/api/v1/mcp",
      "headers": {
        "Authorization": "Bearer msk_u_..."
      }
    }
  }
}
```

Add this to `~/.claude/mcp.json` (Claude Code), Cursor's MCP settings, or Windsurf's `mcp_config.json`. No pip, no npm  -  the current capability-scoped tool catalog appears immediately after a client restart. This is the easiest way to get started.

**Local server (optional):**

```bash
pip install git+https://github.com/Miosa-osa/miosa-mcp.git
```

Or via the TypeScript CLI:

```bash
npx @miosa/cli mcp serve
```

Workspace API keys are server-only. For browser-side preview embedding, your backend mints a short-lived share token. See [Browser Tokens](/docs/platform/browser-tokens/).

## Step 1  -  Create a sandbox.

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! })

const sandbox = await miosa.sandboxes.create({
  templateId: "miosa-sandbox",
  workspaceSlug: "default", // the workspace it belongs to; every create names one
})
console.log(sandbox.id, sandbox.state)
// sbx_a1b2c3d4e5  running
```

```python

from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

sandbox = miosa.sandboxes.create(template_id="miosa-sandbox", workspace_slug="default")
print(sandbox.id, sandbox.state)
# sbx_a1b2c3d4e5  running
```

## Step 2  -  Write a small static site into `/workspace`.

```typescript
await sandbox.files.write(
  "/workspace/index.html",
  `<!doctype html>
<html lang="en">
  <head><meta charset="utf-8"><title>My App</title></head>
  <body><h1>Hello from MIOSA</h1><p>Built in a sandbox.</p></body>
</html>`
)
```

```python
sandbox.files.write(
    "/workspace/index.html",
    """<!doctype html>
<html lang="en">
  <head><meta charset="utf-8"><title>My App</title></head>
  <body><h1>Hello from MIOSA</h1><p>Built in a sandbox.</p></body>
</html>""",
)
```

## Step 3  -  Start a dev server so you can preview it.

```typescript
// Start the dev server. `exec.stream` keeps the process running and yields its output.
const events = sandbox.exec.stream("python3 -m http.server 3000 --bind 0.0.0.0", { cwd: "/workspace" })
for await (const event of events) console.log(event)
```

```python
# Start the dev server in the background.
server = sandbox.commands.run(
    "python3 -m http.server 3000 --bind 0.0.0.0",
    cwd="/workspace",
    background=True,
)
```

## Step 4  -  Create a preview and open it.

```typescript
const preview = await sandbox.previews.create(3000)
console.log(preview.url)
// https://3000-abc12345.sandbox.miosa.ai
```

```python
preview = sandbox.previews.create(port=3000)
print(preview.url)
# https://5173-abc12345.sandbox.miosa.ai
```

   Open the URL in your browser. You see your `index.html` served live from inside the sandbox.

## Step 5  -  Publish to production.

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name my-app \
  --dir /workspace \
  --type docker_deploy \
  --wait \
  --json
```

Use the `deployment.id` and `deployment.public_url` returned by MIOSA.

```typescript
const result = await sandbox.deploy({
  name: "my-app",
  outputPath: "/workspace",
})
// Read the production URL from the response; do not construct it.
console.log(result)
```

```python
result = sandbox.deploy(
    name="my-app",
    output_path="/workspace",
)
# Read the production URL from the response; do not construct it.
print(result)
```

   MIOSA freezes a source snapshot, runs a Builder to package the files, stores an immutable Release, and routes the Deployment URL to it. The sandbox remains alive and editable.

## Step 6  -  Prove the deployment.
The production URL is the URL returned by MIOSA.
Do not construct it from the slug.
Use deployment proof when you need an operator or CI check that the app is live.

```bash
miosa deploy get <deployment-id> --json
```

For Docker Host deployments, proof checks the deployment row, Docker Host host link, host health, durable app target, container route, and public URL probe.

## Step 7  -  Make a change and republish.
Edit `/workspace/index.html` again and publish to the existing deployment:

```bash
miosa deploy create --from-sandbox <sandbox-id> \
  --name <deployment> \
  --dir /workspace \
  --type docker_deploy \
  --wait \
  --json
```

MIOSA creates a new immutable Version and promotes it only after verification succeeds.
The previous healthy version remains available for rollback.

## Step 8  -  (Optional) Attach a custom domain.
   See [Domains](/docs/docker-host/domains/) for the DNS setup. Short version: add a `CNAME` from your domain to the generated host, hit the verify endpoint, MIOSA issues a TLS certificate.

## Step 9  -  Clean up.

```typescript
await sandbox.destroy()
```

```python
sandbox.destroy()
```

   The sandbox is gone. The published deployment and its domain are unaffected  -  the Release is immutable and lives in object storage independently of the sandbox.

### What you just did

| Step | What happened |
|------|--------------|
| `sandboxes.create` | Created an isolated sandbox on the sandbox image |
| `files.write` | Wrote a file into `/workspace` inside the running VM |
| `exec` | Ran a command inside the VM over the exec API |
| `previews.create` | Opened a tunnel from a public hostname to port 3000 inside the VM |
| `sandbox publish` | Froze source, ran Builder, stored Release, created Version, and made it live |
| `deploy prove` | Verified that MIOSA can prove the deployment route and runtime state |
| `sandbox.destroy` | Terminated the VM; deployment is unaffected |

## What's next

- **Add a real backend.** Move from static to dynamic deploys with [Publishing](/docs/docker-host/publishing/) and a managed [Postgres database](/docs/data/postgres/).
- **Authenticate end users.** [Auth-as-a-service](/docs/data/auth/) adds a full JWT signup/login flow with one environment variable.
- **Roll back a bad deploy.** [Rollback](/docs/docker-host/rollback/) repoints the domain at an older version in seconds.
- **Understand every primitive.** [Concepts](/docs/concepts/) is the canonical architecture reference.
- **Build your own product on MIOSA.** The [Platform / White-label overview](/docs/platform/overview/) covers preview tokens, share URLs, tenant branding, per-user quotas, webhook subscriptions, Docker Host domains, and the audit log.
- **Drop in UI components.** `@miosa/react`, `@miosa/vue`, and `@miosa/svelte` provide `MiosaPreview`, `MiosaTerminal`, `MiosaFileTree`, and `MiosaUsage`. See [UI Components](/docs/ui-components/).
- **See a full white-label example.** The [reference integration](https://github.com/Miosa-osa/miosa/tree/main/examples) shows a complete platform embedding.
- **Extend Claude Code with MIOSA skills.** 5 pre-built skills at [github.com/Miosa-osa/miosa-skills](https://github.com/Miosa-osa/miosa-skills) give Claude Code sandbox, computer, and deploy primitives. See [Skills](/docs/guides/skills/).
- **API wire format.** [API Reference](/docs/api-reference/) documents every endpoint.

# Rate limits

URL: https://miosa.ai/docs/rate-limits
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/rate-limits
Source: src/routes/docs/rate-limits/+page.md
Description: The per-workspace and per-endpoint API request limits, how to read the rate-limit headers, and how to back off on 429.

# Rate limits

MIOSA rate-limits API requests per API key, per workspace, and per endpoint group. When you exceed a limit, the API returns HTTP `429` with a `Retry-After` header telling you how many seconds to wait before retrying.

This page covers request throttling only. Hard caps that are not about request rate - concurrent sandboxes, exec and upload limits, webhook retries, browser token TTL - and everything billable live on [Pricing and limits](/docs/pricing/).

## Request limits

| Scope | Limit |
|---|---|
| Per API key | 60 to 30,000 requests per minute, depending on the key's tier |
| Per workspace | Your plan's public-API limit, in requests per minute: Developer 2,500, Business 25,000, Enterprise 100,000 |
| Per endpoint group | Static per-minute caps per endpoint family (for example 30,000 on the public API and 3,000 on event streams) |
| All `/egress/*` endpoints | Current limit returned in `X-RateLimit-*` headers |

Limits can vary by key and policy. Every response carries the current numbers in `X-RateLimit-*` headers, so read them rather than hardcoding the values above.

Contact support to raise a request limit for a heavy integration. Volume terms are negotiated per plan; see the [pricing page](/pricing).

## Handle a 429

```python

def call(url, **kwargs):
    while True:
        res = requests.get(url, **kwargs)
        if res.status_code != 429:
            return res
        time.sleep(int(res.headers.get("Retry-After", "1")))
```

Back off for the number of seconds in `Retry-After`, then retry. Do not retry in a tight loop; `429` is a signal to slow down, not to try harder.

On the opt-in runner endpoint there are two distinct `429`s: `rate_limited` is the per-key or per-tenant limit, and `runtime_busy` (with `Retry-After: 0`) means the runner is at its admission limit and you should retry the request.

# Regions

URL: https://miosa.ai/docs/regions
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/regions
Source: src/routes/docs/regions/+page.md
Description: Which regions MIOSA runs in, what is region-local, how to pin a sandbox or computer to one, and the cross-region story.

# Regions

Every Computer and every Sandbox is created in exactly one region and stays there for its lifetime. A resource does not span regions, and there is no live migration between them today.

## Available regions

| Slug | Location | City | Status |
|---|---|---|---|
| `us-west` | US West | Los Angeles, CA | Live |
| `us-east` | US East | New York, NY | Live |
| `us-mia` | US East 2 | Miami | Live |

All three are generally available and none is restricted. A Computer defaults to your workspace's default region, or `us-mia` when none is set; a Sandbox has no default region and is placed wherever capacity allows.

## Pin a resource to a region

Pass `region` on create; the same field works on Computers and Sandboxes.

```python
computer = client.computers.create(name="ny-build-box", size="M", region="us-east")
print(computer.region)   # "us-east"
```

```typescript
const computer = await client.computers.create({ name: 'ny-build-box', size: 'M', region: 'us-east' });
```

If you omit `region`, a Computer uses your workspace's default region (falling back to `us-mia`), while a Sandbox is placed wherever capacity allows; the response includes the resolved region when one is set. You can change your workspace's default region in dashboard settings; the override applies to Computer creation that omits the field.

| Status | Error | Cause |
|---|---|---|
| 400 | `invalid_region` | Slug not in the list above |
| 503 | `REGION_UNAVAILABLE` | Transient capacity issue; retry or pick another |

## List regions

**`GET /api/v1/regions`** returns the regions available to your tenant, so a region picker in your UI does not need a hardcoded list.

```bash
curl https://api.miosa.ai/api/v1/regions \
  -H "Authorization: Bearer $MIOSA_API_KEY"
```

Each entry has `id` (the region slug), `label`, `active_nodes`, `available`, `small_slots_free`, and a `headroom` object with free slots per size and the region's total and used memory. See the [Regions API](/docs/api-reference/regions/) for the full response shape.

## What is region-local

- **Compute.** The VM runs in one region. All VM sizes are available in every region for both Computers and Sandboxes.
- **Data.** Data services and volumes live in the region of the resource that uses them.
- **Latency.** The three US sites are roughly equidistant for the median US user, so compute performance is effectively identical. Pick by data residency first; otherwise pick by proximity to your users or CI runners, which lowers RTT for desktop streaming and terminal round-trips.

## Cross-region

There is no live migration between regions. To run work in more than one region, create one resource per region, and federate bring-your-own hosts with [OpenComputers](/docs/api-reference/open-computers/) if you want a single logical workspace across them.

EU and APAC regions are on the roadmap and will appear in `GET /api/v1/regions` alongside the current three.

A resource's region (`us-west`, `us-east`, `us-mia`) is separate from the opt-in runner endpoint that serves fast create and exec calls. Region is about where the VM lives; the runner endpoint is about how your request reaches MIOSA. See [regions and the runner](/docs/develop/sandboxes/sizing/) for that distinction.


    Request and response shapes for region listing and errors.

# Sandboxes or Computers?

URL: https://miosa.ai/docs/sandboxes-or-computers
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sandboxes-or-computers
Source: src/routes/docs/sandboxes-or-computers/+page.md
Description: Pick where your app or agent runs on MIOSA: a Sandbox for code, previews and a built-in browser, a Computer for a full desktop, Docker Host to publish.

# Sandboxes or Computers?

Most work starts in a **Sandbox**.
Reach for a **Computer** when someone has to see and use a real screen.
When the result should stay online for your users, publish it with **Docker Host**.


    A fast, isolated machine for code. Run commands, edit files, install packages, open a live preview URL, and drive the built-in browser. Pauses when idle and wakes on the next request.


    A durable cloud desktop. A real Linux screen with a browser, desktop apps, mouse and keyboard control, a live view a person can take over, and state that stays between sessions.


**Ready to go live?** [Docker Host](/docs/docker-host/docker-deploy/) keeps what you built online at a stable URL, with your own domain, versions and rollback.

## Pick by what you need

| You want to | Use |
|---|---|
| Run code, build, test, or install packages | Sandbox |
| Show a live preview of an app while you build it | Sandbox |
| Let an agent browse and fill forms in a browser | Sandbox, with its [built-in browser](/docs/browser-use/) |
| Use desktop apps, or anything that needs a full screen | Computer |
| Keep logins, files and a desktop around for days | Computer |
| Let a person watch and take over an agent's screen | Either: the sandbox browser or the computer desktop both have a live view |
| Keep an app online for your users | Docker Host |

Sandboxes start fastest and cost the least.
Move to a Computer only when the work truly needs a desktop.

## Create one



```bash
# A sandbox for code and previews
miosa create

# A computer with a full desktop
miosa computer create --size small
```




```ts

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const sandbox = await miosa.sandboxes.create({ templateId: "miosa-sandbox" });
const computer = await miosa.computers.create({ name: "research-desk", size: "small" });
```



## Often you use both

A typical agent product writes and runs code in a Sandbox, uses a Computer when a task needs a real desktop, and publishes the finished app with Docker Host.
See [Agent device selection](/docs/guides/agent-device-selection/) for the full decision guide, including when an agent needs no machine at all.

# SDKs overview

URL: https://miosa.ai/docs/sdks
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks
Source: src/routes/docs/sdks/+page.md
Description: Official MIOSA client libraries for TypeScript, Python, Go, Elixir, Java and Rust, with package names, versions, install commands and status.

Official client libraries wrap the MIOSA REST API. Every SDK does authentication, sandboxes, exec and files, snapshots, computers, agents and typed errors. Coverage varies by language; each page marks what a given SDK does not implement yet.

## Languages

## What every SDK shares

- **Auth** with an API key (`msk_u_*`) or an access token, read from the constructor or from `MIOSA_API_KEY`.
- **Sandboxes** with create, list, get and delete.
- **Exec** to run a command, and **files** to read and write inside a machine.
- **Snapshots** and **computers**.
- **Typed errors** carrying a status, a code and a request id.

## Differences to expect

- **Agent definitions** are full CRUD in Elixir; TypeScript has definition CRUD plus separate run APIs; Python, Go and Java expose runs and settings but not definition CRUD. See each page.
- **Sandbox exec in Go, Java and Elixir** runs through a dedicated sandbox exec route; the handle-level convenience methods differ by language.
- **File method names differ** between the sandbox surface and the computer surface even inside one SDK. Each page lists the exact names.

## Secrets

### `secrets.set`  -  Store a secret

```python
sandbox.secrets.set(
    name: str,
    value: str,
    expose_as_env: str,
    scope: str = "sandbox",            # "sandbox" | "user" | "external_user" | "external_workspace" | "tenant"
    external_user_id: str | None = None,
    external_workspace_id: str | None = None,
)
```

Returns `None`. Raises `MiosaAPIError` on validation failure.

```python
sandbox.secrets.set(
    name="openai_key",
    value=os.environ["MY_OPENAI_KEY"],
    expose_as_env="OPENAI_API_KEY",
)
```

```typescript
await sandbox.secrets.set({
  name: string,
  value: string,
  exposeAsEnv: string,
  scope?: 'sandbox' | 'user' | 'external_user' | 'external_workspace' | 'tenant',
  externalUserId?: string,
  externalWorkspaceId?: string,
}): Promise<void>
```

```typescript
await sandbox.secrets.set({
  name: 'openai_key',
  value: process.env.MY_OPENAI_KEY!,
  exposeAsEnv: 'OPENAI_API_KEY',
});
```

```go
err := sandbox.Secrets.Set(ctx, miosa.SecretSet{
    Name:                string,
    Value:               string,

    .scope(String scope)              // optional
    .externalUserId(String id)        // optional
    .externalWorkspaceId(String id)   // optional
    .build());
```

```java
sandbox.secrets().set(SecretSet.builder()
    .name("openai_key")
    .value(System.getenv("MY_OPENAI_KEY"))
    .exposeAsEnv("OPENAI_API_KEY")
    .build());
```

```elixir
Miosa.Secrets.set(sandbox_id, %{
  name: String.t(),
  value: String.t(),
  expose_as_env: String.t(),
  scope: String.t() | nil,               # optional
  external_user_id: String.t() | nil,    # optional
  external_workspace_id: String.t() | nil
})
# Returns {:ok, nil} | {:error, reason}
```

```elixir
{:ok, _} = Miosa.Secrets.set(sandbox.id, %{
  name: "openai_key",
  value: System.get_env("MY_OPENAI_KEY"),
  expose_as_env: "OPENAI_API_KEY"
})
```

---

### `secrets.list`  -  List secrets on a sandbox

Returns metadata only. The `value` field is never returned.

```python
secrets = sandbox.secrets.list()
# Returns List[SecretMeta]
# SecretMeta: name, type, expose_as_env, scope, preview (last 4 chars), last_used_at

for s in secrets:
    print(s.name, s.expose_as_env, s.last_used_at)
```

```typescript
const secrets = await sandbox.secrets.list();
// Returns SecretMeta[]
// SecretMeta: { name, type, exposeAsEnv, scope, preview, lastUsedAt }

for (const s of secrets) {
  console.log(s.name, s.exposeAsEnv, s.lastUsedAt);
}
```

```go
secrets, err := sandbox.Secrets.List(ctx)
// Returns []miosa.SecretMeta

for _, s := range secrets {
    fmt.Println(s.Name, s.ExposeAsEnv, s.LastUsedAt)
}
```

```java
List secrets = sandbox.secrets().list();
for (SecretMeta s : secrets) {
    System.out.println(s.getName() + " " + s.getExposeAsEnv());
}
```

```elixir
{:ok, secrets} = Miosa.Secrets.list(sandbox.id)
Enum.each(secrets, fn s ->
  IO.puts("#{s.name} → #{s.expose_as_env}")
end)
```

---

### `secrets.rotate`  -  Update a secret's value

The placeholder token is unchanged. All sandboxes using this secret pick up the new value on their next request.

```python
sandbox.secrets.rotate("openai_key", new_value="sk-proj-newvalue...")
```

```typescript
await sandbox.secrets.rotate('openai_key', { new_value: 'sk-proj-newvalue...' });
```

```go
err := sandbox.Secrets.Rotate(ctx, "openai_key", "sk-proj-newvalue...")
```

```java
sandbox.secrets().rotate("openai_key", "sk-proj-newvalue...");
```

```elixir
{:ok, _} = Miosa.Secrets.rotate(sandbox.id, "openai_key", "sk-proj-newvalue...")
```

---

### `secrets.delete`  -  Remove a secret

Removes the binding. The sandbox's env var is unset on the next exec.

```python
sandbox.secrets.delete("openai_key")
```

```typescript
await sandbox.secrets.delete('openai_key');
```

```go
err := sandbox.Secrets.Delete(ctx, "openai_key")
```

```java
sandbox.secrets().delete("openai_key");
```

```elixir
{:ok, _} = Miosa.Secrets.delete(sandbox.id, "openai_key")
```

---

## Connect Accounts (OAuth)

### `secrets.connect`  -  Initiate an OAuth flow

```python
flow = sandbox.secrets.connect(
    provider: str,           # "github" | "google" | "slack" | …
    expose_as_env: str,
    scopes: list[str] | None = None,
)
# Returns OAuthFlow
# OAuthFlow: authorize_url (str), wait_for_completion(timeout: int)

print(flow.authorize_url)
flow.wait_for_completion(timeout=300)
```

```typescript
const flow = await sandbox.secrets.connect({
  provider: string,        // 'github' | 'google' | 'slack' | …
  exposeAsEnv: string,
  scopes?: string[],
});
// Returns OAuthFlow
// OAuthFlow: { authorizeUrl: string, waitForCompletion(opts): Promise<void> }

console.log(flow.authorizeUrl);
await flow.waitForCompletion({ timeoutSec: 300 });
```

```go
flow, err := sandbox.Secrets.Connect(ctx, miosa.OAuthConnect{
    Provider:    string,   // "github" | "google" | "slack"
    ExposeAsEnv: string,
    Scopes:      []string,
})
// flow.AuthorizeURL string
// flow.WaitForCompletion(ctx, timeoutSec int) error

fmt.Println(flow.AuthorizeURL)
err = flow.WaitForCompletion(ctx, 300)
```

```java
OAuthFlow flow = sandbox.secrets().connect(OAuthConnect.builder()
    .provider("github")
    .exposeAsEnv("GITHUB_TOKEN")
    .scopes(List.of("repo", "read:user"))
    .build());

System.out.println(flow.getAuthorizeUrl());
flow.waitForCompletion(Duration.ofSeconds(300));
```

```elixir
{:ok, flow} = Miosa.Secrets.connect(sandbox.id, %{
  provider: "github",
  expose_as_env: "GITHUB_TOKEN",
  scopes: ["repo", "read:user"]
})

IO.puts(flow.authorize_url)
{:ok, _} = Miosa.Secrets.wait_for_oauth(flow.id, timeout: 300)
```

---

### `secrets.connect`  -  Start or re-run an OAuth flow

Use to connect a provider, or to re-run an OAuth flow when a token was revoked or scopes changed.

```python
flow = sandbox.secrets.connect(provider="github")
print(flow.authorize_url)
flow.wait_for_completion(timeout=300)
```

```typescript
const flow = await sandbox.secrets.connect({ provider: 'github' });
await flow.waitForCompletion({ timeoutSec: 300 });
```

```go
flow, err := sandbox.Secrets.Connect(ctx, "github")
err = flow.WaitForCompletion(ctx, 300)
```

```java
OAuthFlow flow = sandbox.secrets().connect("github");
flow.waitForCompletion(Duration.ofSeconds(300));
```

```elixir
{:ok, flow} = Miosa.Secrets.connect(client, "github")
```

---

## Network Allowlist

### `network.allow`  -  Add a host to the allowlist

```python
sandbox.network.allow(
    host: str,                  # e.g. "api.openai.com" or "*.openai.com"
    methods: list[str] | None,  # ["GET", "POST"]  -  None means all
    warn_only: bool = False,    # allow but flag in audit log
)
```

```python
sandbox.network.allow("api.openai.com")
sandbox.network.allow("*.anthropic.com", methods=["POST"])
sandbox.network.allow("api.experimental.io", warn_only=True)
```

```typescript
await sandbox.network.allow(
  host: string,
  opts?: { methods?: string[]; warnOnly?: boolean }
)
```

```typescript
await sandbox.network.allow('api.openai.com');
await sandbox.network.allow('*.anthropic.com', { methods: ['POST'] });
await sandbox.network.allow('api.experimental.io', { warnOnly: true });
```

```go
err := sandbox.Network.Allow(ctx, "api.openai.com", miosa.AllowOpts{})
err = sandbox.Network.Allow(ctx, "*.anthropic.com", miosa.AllowOpts{
    Methods:  []string{"POST"},
})
err = sandbox.Network.Allow(ctx, "api.experimental.io", miosa.AllowOpts{
    WarnOnly: true,
})
```

```java
sandbox.network().allow("api.openai.com");
sandbox.network().allow("*.anthropic.com", AllowOpts.builder().methods(List.of("POST")).build());
```

```elixir
{:ok, _} = Miosa.Network.allow(sandbox.id, "api.openai.com")
{:ok, _} = Miosa.Network.allow(sandbox.id, "*.anthropic.com", methods: ["POST"])
```

---

### `network.deny`  -  Explicitly block a host

Deny rules win over allow rules.

```python
sandbox.network.deny("169.254.169.254")
```

```typescript
await sandbox.network.deny('169.254.169.254');
```

```go
err := sandbox.Network.Deny(ctx, "169.254.169.254")
```

```java
sandbox.network().deny("169.254.169.254");
```

```elixir
{:ok, _} = Miosa.Network.deny(sandbox.id, "169.254.169.254")
```

---

### `network.lockdown` and `network.observe`

```python
sandbox.network.lockdown()   # enforce mode  -  apply allowlist
sandbox.network.observe()    # audit-only  -  log everything, block nothing
```

```typescript
await sandbox.network.lockdown();
await sandbox.network.observe();
```

```go
err := sandbox.Network.Lockdown(ctx)
err = sandbox.Network.Observe(ctx)
```

```java
sandbox.network().lockdown();
sandbox.network().observe();
```

```elixir
{:ok, _} = Miosa.Network.lockdown(sandbox.id)
{:ok, _} = Miosa.Network.observe(sandbox.id)
```

---

### `network.suggestions`  -  Hosts observed in a time window

```python
hosts = sandbox.network.suggestions(since: str = "7d")
# Returns List[HostSuggestion]
# HostSuggestion: host, request_count, last_seen, methods

for h in hosts:
    print(h.host, h.request_count)
```

```typescript
const hosts = await sandbox.network.suggestions({ since?: string });
// Returns HostSuggestion[]
// HostSuggestion: { host, requestCount, lastSeen, methods }
```

```go
hosts, err := sandbox.Network.Suggestions(ctx, miosa.SuggestionsOpts{Since: "7d"})
// returns []miosa.HostSuggestion
```

```java
List hosts = sandbox.network().suggestions(SuggestionsOpts.builder()
    .since("7d").build());
```

```elixir
{:ok, hosts} = Miosa.Network.suggestions(sandbox.id, since: "7d")
```

---

### `network.suggestions`  -  Hosts the sandbox contacted

```python
suggestions = sandbox.network.suggestions()
# Returns the hosts the sandbox has contacted.
for host in suggestions:
    print(host["host"], host.get("request_count"))
```

```typescript
const suggestions = await sandbox.network.suggestions();
// Returns the hosts the sandbox has contacted.
for (const host of suggestions) console.log(host.host, host.request_count);
```

```go
suggestions, err := sandbox.Network.Suggestions(ctx)
```

```java
var suggestions = sandbox.network().suggestions();
```

```elixir
{:ok, suggestions} = Miosa.Network.suggestions(client)
```

---

### `network.policies`  -  Inspect current policies

```python
policies = sandbox.network.policies()
for policy in policies:
    print(policy["id"], policy["mode"])  # "observe" | "enforce"
```

```typescript
const policies = await sandbox.network.policies();
for (const policy of policies) console.log(policy.id, policy.mode);
```

```go
policies, err := sandbox.Network.Policies(ctx)
```

```java
var policies = sandbox.network().policies();
```

```elixir
{:ok, policies} = Miosa.Network.policies(client)
```

---

## Audit Log

### `audit.list`  -  Query audit events

Every row has: `timestamp`, `host`, `method`, `path`, `action`, `status_code`, `duration_ms`, `bytes_in`, `bytes_out`, `request_transforms`, `mcp`.

```python
events = sandbox.audit.list(
    since: str = "1h",                # "15m" | "1h" | "24h" | "7d" | "30d" | ISO8601
    host: str | None = None,          # exact or glob, e.g. "*.openai.com"
    method: str | None = None,        # "GET" | "POST" | …
    action: str | None = None,        # "allow" | "reject" | "stub" | "error"
    limit: int = 100,                 # max 1000
    external_user_id: str | None = None,
    external_workspace_id: str | None = None,
)
# Returns List[AuditEvent]
```

```python
events = sandbox.audit.list(since="1h", host="api.openai.com", action="allow")
for e in events:
    print(e.timestamp, e.host, e.status_code, e.duration_ms, "ms")
```

```typescript
const events = await sandbox.audit.list({
  since?: string,
  host?: string,
  method?: string,
  action?: 'allow' | 'reject' | 'stub' | 'error',
  limit?: number,
  externalUserId?: string,
  externalWorkspaceId?: string,
}): Promise<AuditEvent[]>
```

```typescript
const events = await sandbox.audit.list({ since: '1h', action: 'reject' });
for (const e of events) {
  console.log(e.timestamp, e.host, e.statusCode, e.durationMs, 'ms');
}
```

```go
events, err := sandbox.Audit.List(ctx, miosa.AuditListOpts{
    Since:  "1h",
    Host:   "api.openai.com",
    Action: "allow",
    Limit:  100,
})
for _, e := range events {
    fmt.Println(e.Timestamp, e.Host, e.StatusCode, e.DurationMs, "ms")
}
```

```java
List events = sandbox.audit().list(AuditListOpts.builder()
    .since("1h")
    .host("api.openai.com")
    .action("allow")
    .limit(100)
    .build());

for (AuditEvent e : events) {
    System.out.println(e.getTimestamp() + " " + e.getHost() + " " + e.getStatusCode());
}
```

```elixir
{:ok, events} = Miosa.Audit.list(sandbox.id, since: "1h", host: "api.openai.com", action: "allow")
Enum.each(events, fn e ->
  IO.puts("#{e.timestamp} #{e.host} #{e.status_code} #{e.duration_ms}ms")
end)
```

---

### `audit.tail`  -  Live stream of audit events

Blocks and yields events as they arrive over a WebSocket.

```python
# Blocks forever; break out when needed
for event in sandbox.audit.tail():
    print(event.host, event.action, event.status_code)
    if event.action == "reject":
        break
```

```typescript
// The TypeScript SDK has no live tail; poll audit.list().
const events = await sandbox.audit.list({ since: '1h' });
for (const event of events) {
  console.log(event.host, event.action, event.status_code);
  if (event.action === 'reject') break;
}
```

```go
stream, err := sandbox.Audit.Tail(ctx)
for {
    event, err := stream.Next()
    if err != nil { break }
    fmt.Println(event.Host, event.Action, event.StatusCode)
    if event.Action == "reject" { break }
}
```

```java
try (AuditStream stream = sandbox.audit().tail()) {
    for (AuditEvent event : stream) {
        System.out.println(event.getHost() + " " + event.getAction());
        if ("reject".equals(event.getAction())) break;
    }
}
```

```elixir
Miosa.Audit.tail(sandbox.id, fn event ->
  IO.puts("#{event.host} #{event.action} #{event.status_code}")
  if event.action == "reject", do: :stop, else: :continue
end)
```

---

### `audit.list`  -  Query events and export client-side

There is no server-side export endpoint; query with `audit.list(...)` and write the file yourself.

```python

events = sandbox.audit.list(since="30d")
with open("audit-30d.csv", "w", newline="") as f:
    w = csv.writer(f)
    w.writerow(["host", "method", "path", "action", "status_code"])
    for e in events:
        w.writerow([e["host"], e["method"], e["path"], e["action"], e["status_code"]])
```

```typescript
const events = await sandbox.audit.list({ since: '30d' });
// Write `events` to CSV or JSON in your own process.
```

---

## Tenant-level methods

Some operations apply across your entire tenant rather than a single sandbox. These use `client` rather than `sandbox`.

### `client.secrets.set`  -  Scope a secret at tenant or workspace level

```python
# Tenant-wide credential  -  all sandboxes in the tenant resolve it
client.secrets.set(
    name="openai_key",
    value="sk-proj-...",
    scope="tenant",
    expose_as_env="OPENAI_API_KEY",
)

# External-user credential
client.secrets.set(
    name="user_openai_key",
    value="sk-proj-...",
    scope="external_user",
    external_user_id="dana@example.net",
    expose_as_env="OPENAI_API_KEY",
)
```

```typescript
await client.secrets.set({
  name: 'openai_key',
  value: 'sk-proj-...',
  scope: 'tenant',
  exposeAsEnv: 'OPENAI_API_KEY',
});
```

```go
err := client.Secrets.Set(ctx, miosa.SecretSet{
    Name:        "openai_key",
    Value:       "sk-proj-...",
    Scope:       "tenant",
    ExposeAsEnv: "OPENAI_API_KEY",
})
```

```java
client.secrets().set(SecretSet.builder()
    .name("openai_key")
    .value("sk-proj-...")
    .scope("tenant")
    .exposeAsEnv("OPENAI_API_KEY")
    .build());
```

```elixir
{:ok, _} = Miosa.Secrets.set(client, %{
  name: "openai_key", value: "sk-proj-...",
  scope: "tenant",
  expose_as_env: "OPENAI_API_KEY"
})
```

### `client.audit.list`  -  Tenant-wide audit query

Same parameters as `sandbox.audit.list` plus optional `external_user_id` / `external_workspace_id` filter.

```python
# All activity by one end-user across all sandboxes
events = client.audit.list(
    since="7d",
    external_user_id="dana@example.net",
)

# All activity for one workspace
events = client.audit.list(
    since="30d",
    external_workspace_id="acme",
)
```

```typescript
const events = await client.audit.list({
  since: '7d',
  externalUserId: 'dana@example.net',
});
```

```go
events, err := client.Audit.List(ctx, miosa.AuditListOpts{
    Since:          "7d",
    ExternalUserID: "dana@example.net",
})
```

```java
List events = client.audit().list(AuditListOpts.builder()
    .since("7d")
    .externalUserId("dana@example.net")
    .build());
```

```elixir
{:ok, events} = Miosa.Audit.list(client, %{since: "7d", external_user_id: "dana@example.net"})
```

# Elixir SDK

URL: https://miosa.ai/docs/sdks/elixir
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks/elixir
Source: src/routes/docs/sdks/elixir/+page.md
Description: Install, authenticate and use the miosa Elixir SDK 1.1.0 - sandboxes, exec, files, snapshots, computers, agents and typed errors.

The official Elixir SDK for MIOSA. Hex package `miosa`, version 1.1.0. Requires Elixir 1.15 or newer. Every resource returns `{:ok, value} | {:error, %Miosa.Error{}}`.

## Install

```elixir
{:miosa, "~> 1.1"}
```

The OTP application starts a shared named Finch pool (`:miosa_finch_pool`), so there is no config block to add. A client can also be started as a supervised child:

```elixir
{Miosa.Client, api_key: System.fetch_env!("MIOSA_API_KEY")}
```

## Authentication

```elixir
client = Miosa.client("msk_u_...")
client = Miosa.client_from_env()
```

`Miosa.client(api_key, opts)` takes `:base_url` (default `https://api.miosa.ai/api/v1`), `:timeout` (default 30s), `:receive_timeout` (default 60s), `:retry` (default `false`), `:tenant` (sent as `X-MIOSA-Tenant`), `:user_agent` and `:app_info`. The constructor raises `ArgumentError` when the credential is not `msk_`, `mat_` or JWT shaped.

`Miosa.client_from_env()` reads `MIOSA_API_KEY`, then `MIOSA_ACCESS_TOKEN`, `MIOSA_BASE_URL` and `MIOSA_TENANT`. `Miosa.Client.with_tenant(client, tenant)` returns a client acting in another organization.

Retry defaults to `false` in this SDK, unlike Java, which retries three times by default.

## Sandboxes

A sandbox is a computer with `template_id: "miosa-sandbox"`, created through `Miosa.Sandboxes`.

```elixir
{:ok, sandbox} = Miosa.Sandboxes.create(client, %{name: "my-box"})
{:ok, _} = Miosa.Sandboxes.wait_until_ready(client, sandbox["id"])
```

| Function | What it does |
|---|---|
| `Miosa.Sandboxes.create(client, params, opts \\ [])` | Create (`:wait`, `:bill_to`, `:idempotency_key`) |
| `Miosa.Sandboxes.create_with_meta(client, params, opts)` | Create, plus wait and bill-to meta |
| `Miosa.Sandboxes.list(client, opts)` / `list_page/2` | List |
| `Miosa.Sandboxes.get(client, id)` | Get one |
| `Miosa.Sandboxes.delete(client, id)` | Delete |
| `Miosa.Sandboxes.extend/3`, `stop/2`, `pause/2`, `resume/2`, `fork/3` | Lifecycle |
| `Miosa.Sandboxes.wait_until_ready(client, id, opts)` | Wait until ready |

## Exec and files

```elixir
{:ok, %{"stdout" => out}} = Miosa.Sandbox.Exec.run(client, sandbox_id, "node -v")
:ok = Miosa.Sandbox.Exec.stream(client, sandbox_id, "npm run dev", fn ev -> IO.inspect(ev) end)
```

Computer exec is a different module:

```elixir
{:ok, _} = Miosa.Exec.bash(client, computer_id, "ls -la")
{:ok, _} = Miosa.Exec.python(client, computer_id, "print(2 + 2)")
{:ok, cmd} = Miosa.Exec.spawn(client, computer_id, "bash")
```

Files: computer files live in `Miosa.Files`; sandbox files live in `Miosa.Sandbox.Fs` and `Miosa.Sandbox.Files`.

```elixir
:ok = Miosa.Files.write(client, computer_id, "/home/user/notes.txt", "hi")
{:ok, data} = Miosa.Files.download(client, computer_id, "/home/user/notes.txt")
{:ok, entries} = Miosa.Files.list(client, computer_id, "/home/user")

{:ok, _} = Miosa.Sandbox.Fs.write(client, sandbox_id, "/workspace/app.ex", code)
{:ok, _} = Miosa.Sandbox.Fs.read(client, sandbox_id, "/workspace/app.ex")
{:ok, _} = Miosa.Sandbox.Files.tree(client, sandbox_id, "/workspace")
```

`Miosa.Files` methods: `upload`, `download`, `download_to`, `list`, `write`, `export`, `delete`, plus `mkdir`, `rename`, `copy`, `chmod`, `stat`, `readdir`.

## Snapshots

```elixir
{:ok, cp} = Miosa.Checkpoints.create(client, sandbox_id, %{comment: "before deps"})
{:ok, snaps} = Miosa.Snapshots.list(client, limit: 50)
{:ok, _} = Miosa.NamedSnapshots.create(client, %{name: "before-upgrade"})
```

| Surface | Functions |
|---|---|
| `Miosa.Checkpoints` | `create`, `list`, `get`, `delete`, `restore`, `restore_stream` |
| `Miosa.Sandboxes` | `create_snapshot`, `list_snapshots`, `restore_snapshot`, `delete_snapshot` |
| `Miosa.Snapshots` | `list`, `groups`, `get`, `tree`, `wait_tree`, `download`, `fork`, `delete`, `delete_many`, `delete_history` |
| `Miosa.NamedSnapshots` | `list`, `create`, `get`, `delete`, `deploy` |

## Computers

```elixir
{:ok, computer} = Miosa.Computers.create(client, %{name: "dev-box"})
{:ok, _} = Miosa.Computer.start(client, computer["id"])
```

| Function | What it does |
|---|---|
| `Miosa.Computers.create(client, params)` | Create (`:template_type` default `miosa-desktop`, `:size`) |
| `Miosa.Computers.list(client)` | List |
| `Miosa.Computers.get(client, id)` | Get one |
| `Miosa.Computers.delete(client, id, opts)` | Delete (`force: true` for a running computer) |
| `Miosa.Computers.update(client, id, changes)` | Update |

The `Miosa.Computer` handle adds `start`, `stop`, `restart`, `destroy`, `wait_until_running`, `wait_until_stopped`, `clone`, `resize`, `move`, `preview_url`, `public_url`, `urls`, `stream_token`. Desktop control is in `Miosa.Desktop`: `screenshot`, `click`, `double_click`, `right_click`, `drag`, `type`, `key`, `hotkey`, `scroll`, `move`, `windows`, `cursor`, `focus_window`, `launch`, `accessibility_tree`, `get_clipboard`, `set_clipboard`, `screenshot_region`, and the `window_*` helpers.

## Agents

This SDK has full agent definition CRUD.

```elixir
{:ok, agents} = Miosa.Agents.list(client)
{:ok, agent} = Miosa.Agents.create(client, %{name: "reviewer"})
{:ok, _} = Miosa.Agents.duplicate(client, agent["id"], %{name: "reviewer-2"})
```

| Surface | Functions |
|---|---|
| `Miosa.Agents` | `list`, `create`, `get`, `update`, `delete`, `restore`, `duplicate`, `list_runs`, `list_harnesses`, `list_harness_versions`, `list_templates`, `list_defaults`, `put_default` |
| `Miosa.Agents.Settings` / `Credentials` / `Models` / `Signins` / `Chats` / `Triggers` / `Versions` | Sub-namespaces |
| `Miosa.Runs` | Run dispatch and reads |
| `Miosa.Connections` | Model provider and tool connections |

## Errors

```elixir
case Miosa.Sandboxes.get(client, id) do
  {:ok, sandbox} -> sandbox
  {:error, %Miosa.Error{} = err} ->
    if Miosa.Error.retryable?(err), do: :retry
    {err.status, err.code, err.message}
end
```

`Miosa.Error` is a `defexception` with `:message`, `:status`, `:code`, `:body`, `:details`, `:retryable`, `:retry_after_ms` and `:request_id`. Classify with `Miosa.Error.kind/1` (`:unauthorized`, `:insufficient_credits`, `:forbidden`, `:not_found`, `:conflict`, `:validation`, `:rate_limited`, `:server`, `:client`, `:network`), `retryable?/1`, `starting?/1` and `dependents/1`. The bang helpers `Miosa.Exec.bash!/4` and `python!/4` raise instead of returning an error tuple.

`Miosa.Error` parses every server envelope, including the canonical `{"error": {...}}` map form and the 409 bulk-delete `data.blocked` case.

# Go SDK

URL: https://miosa.ai/docs/sdks/go
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks/go
Source: src/routes/docs/sdks/go/+page.md
Description: Install, authenticate and use the miosa-go v2 SDK - sandboxes, exec, files, snapshots, computers, agent runs and typed errors.

The official Go SDK for MIOSA. Module path `github.com/Miosa-osa/miosa-go/v2`, version 2.2.0. Requires Go 1.21 or newer.

## Install

```bash
go get github.com/Miosa-osa/miosa-go/v2
```

```go

```

Subpackages: `github.com/Miosa-osa/miosa-go/v2/sandboxssh` and `github.com/Miosa-osa/miosa-go/v2/computeruse`.

## Authentication

```go
client := miosa.NewClient("msk_u_...")
```

`NewClient(apiKey, opts...)` falls back to `MIOSA_API_KEY` when the key is empty. It also reads `MIOSA_BASE_URL`, `MIOSA_ACCESS_TOKEN` and `MIOSA_TENANT`. Defaults: base URL `https://api.miosa.ai/api/v1`, timeout 60s, 3 retries.

Options: `WithBaseURL`, `WithHTTPClient`, `WithTimeout`, `WithMaxRetries`, `WithTenant`, `WithAccessToken`, `WithBillTo`, `WithDefaultHeader`, `WithUserAgent`. Derive a scoped client with `client.With(opts...)`, `client.AsUser(token)` or `client.ForTenant(id)`.

```go
ctx := miosa.WithBillToContext(context.Background(), "acme")
```

## Sandboxes

Sandbox calls live on `client.Sandboxes`. The `*Sandbox` value is data, not a handle: it has no methods.

```go
sbx, err := client.Sandboxes.Create(ctx, miosa.CreateSandboxInput{Name: "my-box"})
ok, err := client.Sandboxes.WaitUntilReady(ctx, sbx.ID, miosa.WaitUntilReadyOptions{})
```

| Method | What it does |
|---|---|
| `client.Sandboxes.Create(ctx, input)` | Create a sandbox |
| `client.Sandboxes.CreateDetailed(ctx, input)` | Create, plus wait outcome and billed org |
| `client.Sandboxes.Get(ctx, id)` | Get one |
| `client.Sandboxes.GetByName(ctx, name)` | Get by name |
| `client.Sandboxes.List(ctx, input)` / `ListPage` / `ListAll` | List (paged or all) |
| `client.Sandboxes.Delete(ctx, id)` | Delete |
| `client.Sandboxes.Update(ctx, id, in)` | Update |
| `client.Sandboxes.Stop/Pause/Resume/Extend` | Lifecycle |
| `client.Sandboxes.Usage(ctx, id)` | Usage |
| `client.Sandboxes.WaitUntilReady(ctx, id, opts)` | Wait until ready |

The `*Sandbox` value has fields such as `ID` and `PreviewURL` but no methods. Call exec, destroy and readiness on `client.Sandboxes` with the sandbox id.

## Exec and files

```go
res, err := client.Sandboxes.Exec(ctx, sbx.ID, miosa.ExecSandboxInput{Command: "node -v"})
events, err := client.Sandboxes.ExecStream(ctx, sbx.ID, miosa.ExecSandboxInput{Command: "npm run dev"})
```

Computer exec uses a WebSocket service:

```go
out, err := computer.Exec.Bash(ctx, "ls -la")
out, err = computer.Exec.Python(ctx, "print(2 + 2)")
```

Files are computer-scoped. Scope an unscoped client with `For`:

```go
files := client.Files.For(computer.ID)
_ = files.Upload(ctx, "./notes.txt", "/home/user/notes.txt")
data, _ := files.Download(ctx, "/home/user/notes.txt")
list, _ := files.List(ctx, "/home/user")
_ = files.Mkdir(ctx, "/home/user/data")
_ = files.Rename(ctx, "/home/user/a", "/home/user/b")
```

`client.Files` and `computer.Files` are the same service; `computer.Files` is pre-scoped. Methods: `Upload`, `UploadReader`, `Download`, `DownloadTo`, `List`, `Stat`, `Mkdir`, `Rename`, `Copy`, `Chmod`, `Readdir`, `Delete`, `Export`. `FS(workingDir)` returns a path-scoped `ScopedFS`.

## Snapshots

Five surfaces.

```go
snap, err := client.Sandboxes.CreateSnapshot(ctx, sbx.ID, miosa.CreateSandboxSnapshotInput{})
snaps, err := client.Sandboxes.ListSnapshots(ctx, sbx.ID)
_, err = client.Sandboxes.RestoreSnapshot(ctx, sbx.ID, snap.ID)
```

| Surface | Methods |
|---|---|
| `client.Sandboxes` | `CreateSnapshot`, `ListSnapshots`, `RestoreSnapshot`, `DeleteSnapshot` |
| `computer.Snapshots` | `Create`, `List`, `Get`, `Delete`, `Events` |
| `client.Snapshots` | `List`, `Groups`, `Get`, `Delete`, `DeleteMany`, `Fork`, `Tree`, `Download` |
| `client.NamedSnapshots` | `List`, `Get`, `Save`, `Remove`, `Deploy` |
| `client.SnapshotsStandalone` | `List`, `Get` (untyped data) |

## Computers

```go
computer, err := client.Computers.Create(ctx, miosa.CreateComputerInput{Name: "dev-box"})
err = computer.Start(ctx)
```

| Method | What it does |
|---|---|
| `client.Computers.Create(ctx, input)` | Create |
| `client.Computers.List(ctx, input)` | List |
| `client.Computers.Get(ctx, id)` | Get one |
| `client.Computers.Delete(ctx, id)` | Delete |

The `Computer` handle adds `Start`, `Stop`, `Restart`, `Destroy`, `Wait`, `Bash`, `Python`, `PreviewURL`, `PublicURL`, `Clone`, `Resize`, `Move`, `VncCredentials`, `StreamToken`. Desktop: `Screenshot` (bytes), `Click`, `LeftClick`, `DoubleClick`, `RightClick`, `Drag`, `Scroll`, `Type`, `Key`, `Hotkey`, `MoveMouse`, `Launch`, `Windows`, `Cursor`, `Clipboard`, `SetWallpaper`, `AccessibilityTree`, `ViewerURL`.

## Agents

`client.Agents` is settings and catalog only. There is no agent definition CRUD in this SDK.

```go
settings, err := client.Agents.Settings(ctx, workspaceID)
catalog, err := client.Agents.Harnesses(ctx)
```

| Surface | Methods |
|---|---|
| `client.Agents` | `Settings`, `SetDefaultHarness`, `UpdateHarness`, `Models`, `Credentials`, `PutCredential`, `DeleteCredential`, `Harnesses`, `ChatContext`, `CompactChat` |
| `client.AgentAccounts` | `List`, `CreateAPIKey`, `Delete`, `StartSignin`, `GetSignin`, `SubmitSigninCode`, `CancelSignin` |
| `client.Runs` | `Run(ctx, RunCreateInput)`, `Usage(ctx, opts)` |
| `client.Sandboxes` | `QueueAgentPrompt`, `StopAgent` |

**Not yet in this SDK:** creating, listing, updating and deleting agent definitions.

## Errors

Calls return ordinary Go errors. Inspect them with `errors.As`:

```go
var apiErr *miosa.MiosaError
if errors.As(err, &apiErr) {
    if miosa.IsCode(err, "SANDBOX_STARTING") { /* retry */ }
    fmt.Println(apiErr.StatusCode, apiErr.Code, apiErr.RequestID)
}
```

`MiosaError` has `StatusCode`, `Message`, `RequestID`, `Body`, `Code`, `Details`, `Retryable` and `RetryDelay`, plus `ShouldRetry()`. Typed subclasses: `AuthenticationError` (401), `InsufficientCreditsError` (402), `PermissionError` (403), `NotFoundError` (404), `ValidationError` (422), `RateLimitError` (429, adds `RetryAfter`), `ServerError` (5xx), `ConnectionError`. Helpers: `AsMiosaError`, `ErrorCode`, `IsCode`, `IsStarting`, `RetryAfter`.

# Java SDK

URL: https://miosa.ai/docs/sdks/java
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks/java
Source: src/routes/docs/sdks/java/+page.md
Description: Install, authenticate and use the miosa Java SDK 0.5.1 - sandboxes, exec, files, snapshots, computers, agent runs and thrown exceptions.

The official Java SDK for MIOSA. Coordinates `ai.miosa:miosa-sdk`, version 0.5.1. Requires Java 11 or newer. Built on `java.net.http.HttpClient` and Jackson.

## Install

```xml
<dependency>
    <groupId>ai.miosa</groupId>
    <artifactId>miosa-sdk</artifactId>
    <version>0.5.1</version>
</dependency>
```

```groovy
implementation 'ai.miosa:miosa-sdk:0.5.1'
```

```kotlin
implementation("ai.miosa:miosa-sdk:0.5.1")
```

## Authentication

```java

MiosaClient client = new MiosaClient("msk_u_...");
MiosaClient fromEnv = MiosaClient.fromEnv();
```

Constructors: `new MiosaClient(apiKey)`, `(apiKey, baseUrl)` and `(apiKey, baseUrl, timeoutMs, maxRetries)`. Defaults: base URL `https://api.miosa.ai/api/v1`, timeout 30s, 3 retries. An empty key throws `IllegalArgumentException`.

`MiosaClient.fromEnv()` reads `MIOSA_API_KEY`, then `MIOSA_ACCESS_TOKEN`, `MIOSA_BASE_URL` and `MIOSA_TENANT`. The string constructors ignore the environment. A builder adds tenant, user agent and app info:

```java
MiosaClient client = MiosaClient.builder("msk_u_...")
    .tenant("acme")
    .appInfo("Acme", "3.2")
    .build();
client.withTenant("other-org");
```

## Sandboxes

Sandbox calls live on `miosa.sandboxes()`.

```java
Computer sbx = client.sandboxes().create("my-box", "small");
boolean ready = client.sandboxes().waitUntilReady(sbx.getId(), WaitOptions.builder().build());
```

| Method | What it does |
|---|---|
| `sandboxes().create(name)` | Create (`miosa-sandbox`, `small`) |
| `sandboxes().create(name, size)` | Create with a size |
| `sandboxes().create(name, templateType, size)` | Create with template and size |
| `sandboxes().create(options)` | Create from a full parameter map |
| `sandboxes().get(id)` | Get one |
| `sandboxes().list(query)` / `list()` | List |
| `sandboxes().listPage(query)` | Paged list |
| `sandboxes().delete(id)` | Delete |
| `sandboxes().extend(id, seconds)` | Extend the time to live |
| `sandboxes().stop(id)` / `pause(id)` / `resume(id)` | Lifecycle |
| `sandboxes().usage(id)` | Usage |
| `sandboxes().waitUntilReady(id, WaitOptions)` | Wait until ready |

Sizes are `xs`, `small`, `medium`, `large`, `xl`. Passing raw `cpu_count` / `memory_mb` / `disk_size_mb` requires all three and an exact match to a named contract, else `IllegalArgumentException`.

## Exec and files

```java
CommandResult r = client.sandboxExec().run(sandboxId, "node -v", Map.of());
client.sandboxExec().stream(sandboxId, "npm run dev", Map.of(), ev -> System.out.println(ev));

computer.bash("ls -la");
computer.python("print(2 + 2)");
computer.exec().bash("ls -la", 30);
computer.exec().spawn("bash", SpawnOptions.builder().tty(true).build());
```

Files are computer-scoped. The base `FilesResource` is small; extended writes live in `filesExtended()`.

```java
computer.files().upload("./notes.txt", "/home/user/notes.txt");
byte[] data = computer.files().download("/home/user/notes.txt");
List entries = computer.files().list("/home/user");
computer.files().delete("/home/user/old");

computer.filesExtended().writeFiles(List.of(new FileWrite("/home/user/a.txt", "hi")));
Iterator it = computer.filesExtended().watchDir("/home/user");
```

`FilesResource` has only `upload`, `download`, `list`, `export` and `delete`. **Not yet in this SDK:** a read-by-path (use `download`) and `mkdir` / `rename` on the base files resource.

## Snapshots

```java
Snapshot cp = computer.checkpoints().create("before deps");
Map<String, Object> snaps = client.snapshotHistory().list(Map.of("limit", 50));
```

| Surface | Methods |
|---|---|
| `computer.checkpoints()` | `create`, `list`, `get`, `delete`, `restore` |
| `client.snapshotHistory()` | `list`, `groups`, `get`, `fork`, `delete`, `deleteMany`, `deleteHistory`, `tree`, `awaitTree`, `download` |
| `client.snapshotsStandalone()` | `list`, `get` |
| `client.namedSnapshots()` | `list`, `create`, `get`, `delete`, `deploy` |

## Computers

```java
Computer computer = client.computers().create("dev-box", "miosa-desktop", "small");
computer.start();
```

| Method | What it does |
|---|---|
| `computers().create(name, templateType, size)` | Create (also metadata and attribution overloads) |
| `computers().list()` / `list(page, perPage, status)` | List |
| `computers().get(id)` | Get one |
| `computers().delete(id)` | Delete |
| `computers().viewerPassword(id)` / `rotateViewerPassword(id)` | Viewer password |

The `Computer` handle adds `start`, `stop`, `destroy`, `refresh`, `wait(seconds)`, `clone`, `resize`, `move`, `previewUrl(port)`, `publicUrl`, `screenshot`, `screenshotBase64`, `click`, `rightClick`, `doubleClick`, `type`, `key`, `scroll`, `drag`, `launch`, `windows`, `cursor`, `focusWindow`, `bash`, `python`, `desktop()`, `files()`, `exec()`, `checkpoints()`, `services()`, `env()`, `terminal()`.

## Agents

There is no agent definition CRUD resource in this SDK. Agent surfaces are settings and runs only.

```java
client.agentSettings().get(workspaceId);
client.runs().run(Map.of("instruction", "...", "target_kind", "sandbox", "target_id", sbx.getId()));
```

| Surface | Methods |
|---|---|
| `client.agentSettings()` | `get`, `setDefaultHarness`, `updateHarness` |
| `client.agentCredentials()` / `agentModels()` / `agentSignins()` / `agentChats()` | Settings and sign-in |
| `client.runs()` | Run dispatch and reads |
| `client.connections()` | Model provider and tool connections |

**Not yet in this SDK:** creating, listing, updating and deleting agent definitions.

## Errors

Methods throw unchecked exceptions extending `MiosaException`:

```java

try {
    client.sandboxes().get("missing");
} catch (RateLimitException e) {
    System.out.println(e.getRetryAfter());
} catch (MiosaException e) {
    System.out.println(e.getStatusCode() + " " + e.getCode() + " " + e.getRequestId());
}
```

`MiosaException` carries `getStatusCode()`, `getCode()`, `getBody()`, `getRequestId()`, `getDetails()`, `isRetryable()`, `getRetryAfterMs()`, `getKind()` and `isStarting()`. Subclasses: `AuthException`, `InsufficientCreditsException`, `NotFoundException`, `ConflictException`, `RateLimitException`, `ValidationException`, `ServerException`, `NetworkException`, `TimeoutException`, `ResourceStartingException`, `SnapshotInUseException`. Branch on `getKind()`, an `ErrorKind` classified by API code first, then status.

# Python SDK

URL: https://miosa.ai/docs/sdks/python
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks/python
Source: src/routes/docs/sdks/python/+page.md
Description: Install, authenticate and use the miosa Python SDK 2.16.5 - sync and async, sandboxes, exec, files, snapshots, computers, agents and typed errors.

The official Python SDK for MIOSA. Every resource has a sync and an async class: pick `Miosa` or `AsyncMiosa` at construction. Requires Python 3.9 or newer.

## Install

```bash
pip install miosa
```

```python
from miosa import Miosa, AsyncMiosa, Sandbox, Computer, Forge
```

Extras: `miosa[events]` (websockets), `miosa[http2]`, `miosa[dev]`. The agent runtime is a separate module: `from miosa.agent import Agent`.

## Authentication

```python
from miosa import Miosa

client = Miosa(api_key="msk_u_...")           # sync
async_client = AsyncMiosa(api_key="msk_u_...") # async
```

`api_key` and `access_token` are mutually exclusive: passing both raises `ValueError`. Key resolution order is `access_token`, `api_key`, `MIOSA_ACCESS_TOKEN`, `MIOSA_API_KEY`. Other options: `tenant` (`MIOSA_TENANT`), `base_url` (`MIOSA_BASE_URL`, default `https://api.miosa.ai/api/v1`), `timeout` (default 60s), `max_retries` (default 3), `unbranded`.

Both clients are context managers. `client.with_tenant(tenant)` returns a client acting in another organization. Use `client.get_balance()`, `client.get_usage()` and `client.get_transactions()` for account reads.

## Sandboxes

```python
sbx = client.sandboxes.create(name="my-box", size="small")
sbx.wait_until_ready()
```

| Method | What it does |
|---|---|
| `client.sandboxes.create(template_id=None, *, name=None, size=None, ...)` | Create a sandbox |
| `client.sandboxes.list(*, state=None, tags=None, ...)` | List |
| `client.sandboxes.get(sandbox_id)` | Get one |
| `client.sandboxes.get_by_name(name)` | Get by name |
| `client.sandboxes.get_or_create(name, *, resume=True, ...)` | Reuse or create |
| `client.sandboxes.delete(sandbox_id)` | Delete |

On the handle, `sandbox.stop()` stops it (the disk is kept, processes are not) and `sandbox.resume()` brings it back; `sandbox.destroy()` deletes it (`delete` is an alias). Sizes are `xs`, `small`, `medium`, `large`, `xl`.

`Sandbox` and `Computer` destroy themselves on `__exit__`. A `with client.sandboxes.create(...) as sbx:` block deletes the sandbox at block exit.

## Exec and files

```python
r = sbx.exec.run("node -v")      # ExecResult(stdout, stderr, exit_code, duration_ms)
sbx.exec("npm test")             # the exec runner is callable
sbx.run("npm test")              # delegates to exec.run
for ev in sbx.exec.stream("npm run dev"):
    print(ev)
sbx.commands.run("ls -la")       # richer: background processes, pid
```

Computer exec is separate:

```python
computer.bash("ls -la")
computer.python("print(2 + 2)")
```

Files differ between sandboxes and computers. Sandbox files have no `mkdir` or `rm`:

```python
sbx.files.write("/workspace/app.py", code)
sbx.files.read_text("/workspace/app.py")
sbx.files.list("/workspace")
# directory create/remove: use exec
sbx.exec.run("mkdir -p /workspace/out")

computer.files.write_file("/home/user/notes.txt", "hi")
computer.files.mkdir("/home/user/data", recursive=True)
computer.files.delete("/home/user/old")
```

Sandbox file methods: `list`, `read`, `read_text`, `write`, `write_many`, `upload`, `download`, `stat`, `tree`, `watch`. Flat shims on the handle: `write_file`, `read_file`, `list_files`, `stat_file`, `upload`, `download`.

## Snapshots

```python
sbx.snapshots.create(comment="before deps")
sbx.snapshots.list()
sbx.snapshots.restore(snapshot_id)
sbx.create_snapshot()            # convenience
```

| Surface | Methods |
|---|---|
| `sbx.snapshots` | `create`, `list`, `restore`, `delete` |
| `client.snapshots` | `list`, `get` |
| `client.snapshot_history` | `list`, `groups`, `get`, `delete`, `bulk_delete`, `tree`, `file`, `fork` |
| `client.named_snapshots` | `list`, `create`, `get`, `delete`, `deploy` |

## Computers

```python
computer = client.computers.create(name="dev-box", size="small")
computer.start()
computer.wait_until_ready()
```

| Method | What it does |
|---|---|
| `client.computers.create(name, *, template_type="miosa-desktop", size="small", ...)` | Create |
| `client.computers.list(*, workspace_id=None)` | List |
| `client.computers.get(computer_id)` | Get one |
| `client.computers.update(computer_id, ...)` | Update |
| `client.computers.delete(computer_id)` | Delete |

Desktop control: `screenshot()` (bytes), `screenshot_base64()`, `click`, `right_click`, `double_click`, `type`, `key`, `hotkey`, `scroll`, `drag`, `move_cursor`, `launch`, `windows`, `accessibility_tree`, `set_clipboard`, `set_wallpaper`.

## Agents

There is no `client.agents`. Agent surfaces:

```python
computer.agent.run("open the editor")     # computer control session
client.runs.run(instruction="...", target_kind="sandbox", target_id=sbx.id)
sbx.run_agent("fix tests")                # convenience, runner "claude-code"
sbx.prompt("fix tests")                   # convenience, provider "claude"
```

| Surface | Purpose |
|---|---|
| `computer.agent` | Control sessions: `run`, `list`, `get`, `cancel`, `pause`, `resume`, `task` |
| `client.runs` | `run`, `list`, `get`, `cancel`, `outputs`, `files`, `messages`, `diagnostics` |
| `client.agent_runs` | `run`, `list`, `get`, `cancel`, `artifacts`, `events`, `wait_for_completion` |
| `miosa.agent` | ADK: `Agent`, `miosa_tools`, provider factories |

`miosa.agent.Agent` needs `tools=` or `miosa_api_key=`; it raises `ValueError` otherwise.

## Errors

```python
from miosa import Miosa, RateLimitError

try:
    client.sandboxes.get("missing")
except RateLimitError as err:
    print(err.retry_after)
```

All errors extend `MiosaError`, which carries `status_code`, `code`, `body`, `details`, `request_id`, `retryable` and `retry_after_ms`. Branch on `err.code` (a string), not `err.status_code`. Status-mapped subclasses (`AuthenticationError`, `PermissionError`, `NotFoundError`, `ValidationError`, `RateLimitError`, `InsufficientCreditsError`, `ServerError`, `TimeoutError`, `ConnectionError`) plus around 55 typed errors are exported from the package root.

`PermissionError`, `TimeoutError` and `ConnectionError` shadow Python builtins and derive from `MiosaError`, not from the builtin of the same name. Catch `MiosaError` for a universal handler.

## Services and data, in this SDK

The same client reaches the Services and data surfaces. The method names below
are the ones in 2.19.0, on both the sync and the async client:

```python
# settings as code, replicas and rolling deploys
client.services.update(service_id, settings={"strategy": "rolling"}, shape="dedicated-4", lock_version=3)

# a pull request preview per repository
client.services.set_preview_settings(project_id, repository="acme/api", enabled=True, secret="whsec_...")
metrics = client.services.metrics(project_id, service_id, range="24h")

# log drains
client.services.create_log_drain(project_id, environment_id, name="ops", url="https://logs.example.test/ingest")

# public database endpoint
client.databases.enable_public_networking(database_id, ["203.0.113.0/24"])
```

Protection and WAF are `services.set_protection`, `services.share_link`,
`services.set_waf` and `services.set_attack_mode`.

# Rust SDK

URL: https://miosa.ai/docs/sdks/rust
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks/rust
Source: src/routes/docs/sdks/rust/+page.md
Description: Install, authenticate and use the miosa Rust SDK 0.1.0 - sandboxes, exec, files, computers, agents and a typed error enum.

The crate is named `miosa`, version 0.1.0. It targets Rust 1.85 or newer (edition 2021). The default `ws` feature adds WebSocket support for the terminal, port tunnels and the SSH tunnel; the `blocking` feature adds `BlockingMiosa`, which owns its own Tokio runtime.

## Install

```bash
cargo add miosa
```

```toml
[dependencies]
miosa = "0.1"
```

## Authentication

```rust
use miosa::Miosa;

let client = Miosa::new("msk_u_...")?;
let client = Miosa::from_env()?;
```

`Miosa::new(api_key)` and `Miosa::from_env()` read `MIOSA_API_KEY`, then `MIOSA_ACCESS_TOKEN`, `MIOSA_BASE_URL` and `MIOSA_TENANT`. Defaults: base URL `https://api.miosa.ai/api/v1`, timeout 60s, 3 retries.

The builder sets everything explicitly:

```rust
let client = Miosa::builder()
    .api_key("msk_u_...")
    .tenant("acme")
    .timeout(Duration::from_secs(45))
    .build()?;
```

Builder methods: `api_key`, `access_token`, `base_url`, `tenant`, `workspace`, `bill_to`, `user_agent`, `unbranded`, `timeout`, `max_retries`, `http_client`. Derived clients (which share the connection pool): `with_tenant`, `with_workspace`, `with_bill_to`, `as_user`, `anonymous`, `with_timeout`. Passing both an API key and an access token is an `Error::Config`.

## Sandboxes

```rust
use miosa::CreateSandbox;

let sbx = client.sandboxes().create(CreateSandbox::new().name("my-box")).await?;
let handle = client.sandboxes().handle(sbx.id.clone());
handle.wait_until_ready(Default::default()).await?;
```

| Method | What it does |
|---|---|
| `client.sandboxes().create(options)` | Create (mints an `Idempotency-Key`) |
| `client.sandboxes().create_detailed(options)` | Create, plus wait outcome |
| `client.sandboxes().get(id)` | Get one |
| `client.sandboxes().get_by_name(name)` | Get by name |
| `client.sandboxes().list(filter)` / `list_all` / `list_every` | List |
| `client.sandboxes().delete(id)` | Delete |
| `client.sandboxes().handle(id)` | A `SandboxHandle` for the sandbox |

`CreateSandbox` builder: `name`, `size`, `template_id`, `metadata`, `env`, `timeout_sec`, `idle_timeout_sec`, `persistent`, `always_on`, `environment`, `no_env`, `setup_file`, `wait`, `idempotency_key`. `SandboxHandle` adds `exec`, `pause`, `resume`, `stop`, `extend`, `destroy`, `usage`, `wait_until_ready`, `wait_until_idle`, `fork`, `logs`, `metrics`, `files`, and the snapshot methods.

## Exec and files

```rust
use miosa::ExecOptions;

let r = handle.exec("node -v", ExecOptions::new()).await?;
let mut stream = handle.exec_stream("npm run dev", ExecOptions::new()).await?;
```

`ExecOptions` builder: `cwd`, `env`, `timeout`. Computer exec: `computer.bash("ls -la", ExecOptions::new()).await?` and `computer.python(code, opts)`.

Files are reached through a machine-scoped `Files`:

```rust
let files = handle.files();
files.write("/workspace/app.rs", code.as_bytes()).await?;
let text = files.read("/workspace/app.rs").await?;
let list = files.list(Some("/workspace")).await?;
files.mkdir("/workspace/out", true, None).await?;
files.delete("/workspace/old").await?;
```

`Files` methods: `list`, `readdir`, `stat`, `download`, `read`, `write`, `write_many`, `upload`, `mkdir`, `rename`, `copy`, `chmod`, `delete`. `computer.files()` returns the same type, scoped to that computer.

## Snapshots

There is no top-level snapshots namespace. Snapshots are per-machine on the handles.

```rust
let snap = handle.create_snapshot(SnapshotOptions::default()).await?;
let snaps = handle.list_snapshots().await?;
handle.restore_snapshot(&snap.id).await?;
```

| Handle | Methods |
|---|---|
| `SandboxHandle` | `create_snapshot`, `list_snapshots`, `restore_snapshot`, `delete_snapshot`, `fork` |
| `ComputerHandle` | `create_snapshot`, `list_snapshots`, `restore_snapshot`, `delete_snapshot`, `duplicate(name)` |

**Not yet in this SDK:** account-wide snapshot history, named snapshots, and snapshot tree or download.

## Computers

```rust
let computer = client.computers().create(CreateComputer::default()).await?;
let handle = client.computers().handle(computer.id.clone());
handle.start().await?;
handle.wait_until_ready(Default::default()).await?;
```

| Method | What it does |
|---|---|
| `client.computers().create(options)` | Create |
| `client.computers().get(id)` | Get one |
| `client.computers().list(filter)` / `list_all` | List |
| `client.computers().delete(id)` | Delete |
| `client.computers().handle(id)` | A `ComputerHandle` |

`ComputerHandle` adds `start`, `stop`, `restart`, `resize`, `move_to`, `destroy`, `bash`, `python`, `files`, the snapshot methods, `viewer_password`, `rotate_viewer_password`, `urls`, `vnc_credentials`, `stream_token` and `embed`. Desktop: `screenshot`, `screenshot_region`, `click`, `double_click`, `drag`, `type_text`, `key`, `hotkey`, `key_down`, `key_up`, `scroll`, `move_cursor`, `launch`, `focus_window`, `close_window`, `maximize_window`, `minimize_window`, `set_wallpaper`, `windows`, `clipboard`, `set_clipboard`, `accessibility_tree`, `act(action)`, `look()`.

## Agents

Settings, catalog and triggers. Agent definition CRUD and run dispatch are not in this SDK.

```rust
let harnesses = client.agents().harnesses().await?;
let triggers = client.agents().triggers(&agent_id).await?;
let profile = client.agent_runtime().profiles().await?;
```

| Surface | Methods |
|---|---|
| `client.agents()` | `harnesses`, `harness_versions`, `templates`, `models`, `defaults`, `set_defaults`, `settings`, `set_default_harness`, `update_harness`, `credentials`, `put_credential`, `delete_credential`, `triggers`, `create_trigger`, `update_trigger`, `delete_trigger`, `rotate_trigger_secret`, `fire_trigger`, `chat_context`, `compact_chat` |
| `client.agent_runtime()` | `profiles`, `profile`, `create_profile`, `update_profile`, `delete_profile`, `start_signin`, `signin`, `submit_signin_code`, `cancel_signin` |

**Not yet in this SDK:** creating agents, running agents, and reading run outputs. Many `agents` methods return untyped `serde_json::Value`.

## Errors

The crate has one error type, a `#[non_exhaustive]` enum:

```rust
use miosa::Error;

match result {
    Ok(sbx) => println!("{}", sbx.id),
    Err(e) if e.is_retryable() => { /* back off */ }
    Err(e) => eprintln!("{} {} {}", e.kind_name(), e.status().unwrap_or(0), e.code().unwrap_or("")),
}
```

Variants: `Api(ApiError)`, `Transport`, `Decode`, `Config`, `ToolsetConfig`, `ClientRequired`, `Internal`. `ApiError` carries `kind`, `status`, `code`, `message`, `retryable`, `retry_after`, `request_id`, `details` and `body`, plus `is_code(&str)`. `Error` helpers: `status()`, `code()`, `is_code()`, `retry_after()`, `is_retryable()`, `request_id()`, `api()`, `is_not_found()`, `is_conflict()`, `is_timeout()`, `kind_name()`. Matches on `Error` must include a wildcard arm because the enum is non-exhaustive.

POST and PATCH are only retried when the request carries an `Idempotency-Key`. `sandboxes().create` mints one automatically.

# TypeScript SDK

URL: https://miosa.ai/docs/sdks/typescript
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/sdks/typescript
Source: src/routes/docs/sdks/typescript/+page.md
Description: Install, authenticate and use @miosa/sdk 3.7.1 - sandboxes, exec, files, snapshots, computers, agents and typed errors.

The official TypeScript/JavaScript SDK for MIOSA. Works with Node.js 18+, Deno, Bun and modern bundlers. Fully typed, with no `any`. Named exports only; there is no default export.

## Install

```bash
npm install @miosa/sdk
```

```bash
pnpm add @miosa/sdk
```

```bash
yarn add @miosa/sdk
```

```bash
bun add @miosa/sdk
```

```typescript

```

Two subpath exports add helpers and the computer-use toolset:

```typescript

```

## Authentication

```typescript

const client = new Miosa({ apiKey: "msk_u_..." });
```

The class is `Miosa`. Constructor options: `apiKey` (or the `MIOSA_API_KEY` env var), `accessToken` (a user JWT for org switching), `tenant` (`MIOSA_TENANT`), `baseUrl` (`MIOSA_BASE_URL`, default `https://api.miosa.ai/api/v1`), `timeout` (default 30s) and `maxRetries` (default 3).

`apiKey` and `accessToken` are mutually exclusive: passing both throws. Derive a scoped client with `client.withTenant(tenant)` or `client.withOptions(opts)`, both of which return a new client.

```typescript
const tenant = client.withTenant("acme");
await client.whoami();
```

## Sandboxes

```typescript
const sbx = await client.sandboxes.create({ name: "my-box", size: "small" });
await sbx.waitUntilReady();
```

| Method | What it does |
|---|---|
| `client.sandboxes.create(params?)` | Create a sandbox |
| `client.sandboxes.list(params?)` | List sandboxes |
| `client.sandboxes.get(id)` | Get one sandbox |
| `client.sandboxes.getByName(name)` | Get by name |
| `client.sandboxes.getOrCreate(params)` | Reuse or create |
| `client.sandboxes.listPage(params?)` | Paged list with meta |
| `client.sandboxes.delete(id)` | Delete by id |

`Sandbox.stop()` is in the TypeScript SDK 3.7.5, which is tagged but not yet published to npm; until it is, stop with `POST /api/v1/sandboxes/{id}/stop`.

The `Sandbox` handle adds `destroy()` and `delete()`, plus `pause()`, `resume()`, `fork()`, `extend(seconds)`, `expose(port)`, `getUrl(port, path)`, `usage()` and `waitUntilReady()`.

## Exec and files

Sandbox exec is callable and streamable:

```typescript
const r = await sbx.exec("node -v");            // { stdout, stderr, exitCode }
await sbx.exec.run("npm test", { cwd: "/workspace" });
for await (const ev of sbx.exec.stream("npm run dev")) console.log(ev);
await sbx.commands.execute("echo hi");          // POST /commands, ready-gated
```

Computer exec is a class, not callable:

```typescript
await computer.exec.bash("ls -la");
await computer.exec.python("print(2 + 2)");
const h = computer.exec.stream({ /* ... */ });
```

Sandbox files and computer files use different names:

```typescript
await sbx.files.write("/workspace/app.ts", code);
await sbx.files.readText("/workspace/app.ts");
await sbx.files.list("/workspace");
await sbx.files.remove("/workspace/old");       // sandbox: "remove"

await computer.files.writeFile("/home/user/notes.txt", "hi");
await computer.files.readFile("/home/user/notes.txt");
await computer.files.readdir("/home/user");
await computer.files.delete("/home/user/old");  // computer: "delete"
```

Sandbox file methods: `write`, `read`, `readText`, `list`, `mkdir`, `remove`, `rename`, `copy`, `chmod`, `stat`, `tree`, `writeMany`, `uploadFile`, `download`.

## Snapshots

Three surfaces: account-wide, per sandbox, per computer.

```typescript
await client.snapshots.list();
await client.snapshots.named.create({ name: "before-upgrade", /* ... */ });
await sbx.snapshots.create("before deps");
await computer.checkpoints.create();
```

| Surface | Methods |
|---|---|
| `client.snapshots` | `list`, `groups`, `get`, `tree`, `download`, `fork`, `delete`, `deleteMany`, `deleteHistory` |
| `client.snapshots.named` | `list`, `create`, `get`, `remove`, `deploy` |
| `sbx.snapshots` | `create`, `list`, `restore`, `delete` |
| `computer.checkpoints` | `create`, `list`, `get`, `delete`, `restore` |

## Computers

```typescript
const computer = await client.computers.create({ name: "dev-box" });
await computer.start();
await computer.waitUntilReady();
```

| Method | What it does |
|---|---|
| `client.computers.create(params)` | Create (returns a computer in `creating` state; call `start()`) |
| `client.computers.list(params?)` | List computers |
| `client.computers.get(id)` | Get one |
| `client.computers.update(id, params)` | Update |
| `client.computers.delete(id)` | Delete |

The `Computer` handle drives the desktop: `screenshot()` returns PNG `Uint8Array` (use `screenshotBase64()` for base64), plus `click`, `rightClick`, `doubleClick`, `moveMouse`, `type`, `key`, `hotkey`, `scroll`, `drag`, `launch(app)`, `windows()` and `act(action, ...args)`.

## Agents

Definitions and runs are separate surfaces.

```typescript
await client.agents.list();
await client.agents.create({ /* ... */ });
await client.agents.publish(id, configuration);

const run = await sbx.prompt("fix the failing test");
await computer.run("write a README");
```

| Surface | Purpose |
|---|---|
| `client.agents` | Agent definitions: `list`, `get`, `create`, `update`, `publish`, `archive` |
| `sbx.prompt(...)`, `computer.prompt(...)` | Prompt an agent on a machine (Agent Runs API) |
| `sbx.run(...)`, `computer.run(...)` | Dispatch a run (Runs API) |
| `client.runs` | `run`, `list`, `get`, `cancel`, `waitForCompletion`, `outputs`, `files`, `messages`, `diagnostics`, `usage` |
| `client.agentRuns` | `run`, `list`, `get`, `cancel`, `waitForCompletion`, `streamEvents`, `artifacts`, `downloadArtifact` |

## Errors

Every HTTP failure throws `MiosaError`:

```typescript

try {
  await client.sandboxes.get("missing");
} catch (err) {
  if (err instanceof RateLimitError) console.log(err.retryAfterMs);
}
```

`MiosaError` carries `status`, `code`, `details`, `requestId` and `retryable`. Branch on `error.code`, not `error.status`. All typed subclasses (`AuthError`, `NotFoundError`, `RateLimitError`, `InsufficientCreditsError`, `ValidationError`, `TimeoutError`, `EnvironmentNotFoundError`, `SnapshotInUseError` and many more) are exported from the package root.
## Services and data, in this SDK

Beyond sandboxes and computers, the same client reaches the Services and data
surfaces. The method names below are the ones in 3.8.0:

```ts
// settings as code, replicas and rolling deploys
await miosa.services.update(serviceId, {
  settings: { shape: "dedicated-4", spread: "auto", strategy: "rolling" },
  lock_version: 3,
});

// a pull request preview per repository
await miosa.services.setPreviewSettings(projectId, {
  repository: "acme/api", enabled: true, secret: "whsec_...",
});
const { series, available } = await miosa.services.metrics(projectId, serviceId, "24h");

// log drains
const drain = await miosa.services.createLogDrain(projectId, environmentId, {
  name: "ops", url: "https://logs.example.test/ingest",
});

// public database endpoint
await miosa.databases.enablePublicNetworking(databaseId, ["203.0.113.0/24"]);
```

Protection and WAF are `services.setProtection`, `services.shareLink`,
`services.setWaf` and `services.setAttackMode`.

# Security

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security
Source: src/routes/docs/security/+page.md
Description: Built-in credential vault, outbound network controls, and audit log on every MIOSA sandbox and computer. No setup. Free on all plans.

# Security

Every MIOSA Sandbox and Computer ships with a built-in security boundary. **No setup. No add-on SKU. Free on every plan.**

Three things you can use whenever you need them:

| Feature | What it does | Page |
|---|---|---|
| **Secrets** | Store your API keys in MIOSA  -  sandboxes see opaque placeholders, the real values stay encrypted at rest | [Secrets](/docs/security/secrets) |
| **Connect Accounts** | OAuth-based credential connection (GitHub, Google, Slack, …) instead of pasting raw tokens | [Connect Accounts](/docs/security/connect-accounts) |
| **Network Allowlist** | Watch what your sandbox calls; lock it down to an approved list when you're ready | [Network](/docs/security/network) |
| **Audit Log** | Outbound calls recorded to the egress audit log  -  searchable, exportable, live-tail (capture is not yet enabled in the current release) | [Audit Log](/docs/security/audit-log) |

## Getting started in 60 seconds

Nothing to install. Nothing to configure globally. Each Computer / Sandbox already has the three tabs.

### 1. Add a credential

Open any Sandbox or Computer → **Secrets** tab → **+ Add Secret**

```
Name:         openai_key
Value:        sk-proj-...   ← your real key
Expose as:    OPENAI_API_KEY
```

Or via SDK (Python  -  same shape in TypeScript / Go / Java / Elixir):

```python
sandbox.secrets.set(
    name="openai_key",
    value="sk-proj-...",
    expose_as_env="OPENAI_API_KEY",
)
```

Inside the sandbox, `process.env.OPENAI_API_KEY` is now an opaque `miosa-tok-…` placeholder. Your existing code uses it as normal. The real key is swapped in at the network boundary on the way out.

→ Full walkthrough: [Secrets](/docs/security/secrets)

### 2. Use your code unchanged

```python

requests.post(
    "https://api.openai.com/v1/chat/completions",
    headers={"Authorization": f"Bearer {os.environ['OPENAI_API_KEY']}"},
    json={...},
)
```

That's it. OpenAI sees your real `sk-…`. Your sandbox never does. No code change.

### 3. (Optional) Check what you called + lock it down

After your sandbox has been running for a while:

- **Audit Log tab**  -  live-tail outbound calls. Filter by host, status, time. Egress audit capture is not yet enabled in the current release.
- **Network tab**  -  see the auto-built list of hosts you've contacted. One click to enforce-mode with that list as the allowlist.

Both are opt-in. Audit-only is the default until you decide to lock down.

→ See [Network Allowlist](/docs/security/network) for the lockdown workflow.

### Want to wire up GitHub / Google / Slack instead of pasting tokens?

→ [Connect Accounts](/docs/security/connect-accounts)  -  OAuth flow that handles refresh automatically.

### Building a white-label product on top of MIOSA?

Your end-users don't need MIOSA accounts  -  credentials can be scoped to your own `external_user_id`.

→ [White-label Credentials](/docs/security/white-label)

---

## Your code doesn't change

The whole design rule for MIOSA Security: **your existing code keeps working.**

```python

# This code is identical with or without MIOSA Secrets:
response = requests.post(
    "https://api.openai.com/v1/chat/completions",
    headers={"Authorization": f"Bearer {os.environ['OPENAI_API_KEY']}"},
    json={...},
)
```

What changes is *the value* of `OPENAI_API_KEY`. Without Secrets, it's your real `sk-...` key. With Secrets, it's an opaque placeholder like `miosa-tok-7f2a8c...`. The MIOSA proxy substitutes the real key on the way out. OpenAI sees the real key. Your sandbox never does.

## Three guarantees

New sandboxes do not block anything. The proxy watches and logs but never gets in the way. You only enter "enforce" mode by explicitly clicking Lock Down  -  and it's reversible in one click.

Once saved, secret values are encrypted with ChaCha20-Poly1305. They are unsealed only at the moment the proxy needs to swap them into an outbound request. Nobody  -  including MIOSA engineers  -  can re-read a stored value via the API or UI.

`.env` files still work. `tenant_provider_keys` and `workspace_env_vars` still work. MIOSA Secrets adds a new layer; it doesn't replace anything that exists today.

## Where to go next

- **First time using this?** Start with [Secrets  -  Quickstart](/docs/security/secrets).
- **Want to wire up OAuth (GitHub etc.)?** Read [Connect Accounts](/docs/security/connect-accounts).
- **Want to lock down outbound traffic?** Read [Network Allowlist](/docs/security/network).
- **Building a white-label product on MIOSA?** Read [White-label Credentials](/docs/security/white-label).

## Glossary

**Placeholder token**
An opaque string (format: `miosa-tok-<hex>`) that MIOSA injects into a sandbox's environment in place of a real credential. The proxy swaps the placeholder with the real value on every outbound request. The placeholder is unique per binding  -  it cannot be brute-forced to discover the real key.

**OAuth Connect**
A MIOSA feature that lets you authorize a third-party account (GitHub, Google, Slack, …) via the standard OAuth 2.0 flow instead of pasting a static API key. MIOSA stores the resulting access and refresh tokens, refreshes them automatically, and exposes the current valid access token to the sandbox as a placeholder env var.

**Resolver scope walk**
The ordered lookup MIOSA performs when a sandbox makes an outbound request and the proxy needs to match a placeholder to a real credential. The proxy checks scopes in this priority order: (1) direct sandbox binding, (2) user-scoped secret, (3) external_user-scoped secret, (4) external_workspace-scoped secret, (5) MIOSA workspace secret, (6) tenant-wide secret. First match wins. If nothing matches, the placeholder passes through unchanged and the upstream API call fails (the intended safe behavior).

## Real-world example  -  OpenAI customer-support agent in 5 minutes

This is the complete setup for an AI agent that uses OpenAI safely. Run these five commands and you're done.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

# 1. Create sandbox
sandbox = client.sandboxes.create(template_id="python-ds")

# 2. Store the OpenAI key  -  sandbox never sees the real value
sandbox.secrets.set(
    name="openai_key",
    value=os.environ["MY_OPENAI_KEY"],
    expose_as_env="OPENAI_API_KEY",
)

# 3. Lock down to only api.openai.com
sandbox.network.allow("api.openai.com")
sandbox.network.lockdown()

# 4. Run the agent  -  uses $OPENAI_API_KEY exactly like normal
result = sandbox.exec("""
python3 -c "

resp = requests.post(
    'https://api.openai.com/v1/chat/completions',
    headers={'Authorization': f'Bearer {os.environ[\"OPENAI_API_KEY\"]}'},
    json={'model': 'gpt-4o-mini', 'messages': [{'role': 'user', 'content': 'Hello!'}]}
)
print(resp.json()['choices'][0]['message']['content'])
"
""")
print(result.stdout)

# 5. Check the audit trail
events = sandbox.audit.list(since="5m")
for e in events:
    print(e.host, e.action, e.status_code)
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

// 1. Create sandbox
const sandbox = await client.sandboxes.create({ template: 'python-ds' });

// 2. Store the OpenAI key
await sandbox.secrets.set({
  name: 'openai_key',
  value: process.env.MY_OPENAI_KEY!,
  exposeAsEnv: 'OPENAI_API_KEY',
});

// 3. Lock down
await sandbox.network.allow('api.openai.com');
await sandbox.network.lockdown();

// 4. Run the agent
const result = await sandbox.exec(`
python3 -c "

resp = requests.post(
    'https://api.openai.com/v1/chat/completions',
    headers={'Authorization': f'Bearer {os.environ[\"OPENAI_API_KEY\"]}'},
    json={'model': 'gpt-4o-mini', 'messages': [{'role': 'user', 'content': 'Hello!'}]}
)
print(resp.json()['choices'][0]['message']['content'])
"
`);
console.log(result.stdout);

// 5. Audit trail
const events = await sandbox.audit.list({ since: '5m' });
for (const e of events) {
  console.log(e.host, e.action, e.statusCode);
}
```

## Troubleshooting

**My sandbox's env var contains a placeholder but the API returns 401.**
The proxy couldn't match the placeholder in the outbound request header. Confirm the SDK puts the token in `Authorization: Bearer ...`. See [troubleshooting #1](/docs/security/troubleshooting#1-secret-value-is-not-being-swapped-outbound-request-uses-the-raw-placeholder).

**I enabled lockdown and nothing works.**
Call `sandbox.network.pending()` to see the blocked hosts, then allow them. Or revert with `sandbox.network.observe()` while you diagnose.

**I can't see any audit rows.**
The audit log records outbound calls only. If the sandbox hasn't made any outbound requests, the log is empty. Trigger a call and re-query.

**I see "Reconnect needed" on a GitHub secret.**
The OAuth token was revoked by the user or expired. Call `sandbox.secrets.reauthorize(provider="github")` to re-run the OAuth dance. See [Connect Accounts troubleshooting](/docs/security/troubleshooting#4-github-oauth-refresh-failing--sandbox-gets-401-on-apigithubcom).

# API keys

URL: https://miosa.ai/docs/security/api-keys
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security/api-keys
Source: src/routes/docs/security/api-keys/+page.md
Description: Create, scope, rotate and revoke the keys programs use, with the presets and limits the platform enforces.

# API keys

A key authenticates a program. It carries a list of scopes, an optional workspace
pin, an optional expiry, an optional source-IP allowlist and a rate limit, and it is
shown once, when it is created.

## Everyday commands

```bash
miosa api-key list                      # revoked keys hidden unless --all
miosa api-key create pipeline \
  --preset ci --expires-in 90 --rate-limit 600 \
  --allowed-ip 203.0.113.0/24
miosa api-key get pipeline              # never prints the secret
miosa api-key rotate pipeline           # old secret stops working at once
miosa api-key rm pipeline               # revoke
miosa api-key events pipeline           # when it was used, what changed
```

`--quiet-key` prints only the secret, for a script that pipes it somewhere safe.
A secret cannot be recovered later; rotate to get a new one.

## Scopes

`--scope` takes one scope per flag and can be repeated. A few worth knowing:

| Scope | What it allows |
|---|---|
| `projects:read` / `projects:write` | Projects, Deploy targets, services, releases, preview settings |
| `env:read` / `env:write` / `env:reveal` | Variables, writing them, and reading a value back |
| `sandboxes:read` / `sandboxes:write` / `sandboxes:exec` | Sandbox lifecycle and commands |
| `databases:read` / `databases:write` | Managed databases, including the public endpoint |
| `deployments:read` / `deployments:write` | Docker Host deployments |
| `previews:read` / `previews:write` | Sandbox previews, not pull-request previews |

Pull-request preview settings are `projects:read` / `projects:write`: the sandbox
`previews:*` scopes never grant them.

## Presets

`miosa api-key presets` lists what the server offers; `--preset` picks one at
create time. The named ones are `read-only`, `ci`, `agent`, `cli`, `automation`
and `full-access`. A preset is a starting point, not a ceiling: add `--scope` for
anything it does not include, and the created key lists exactly what it holds.

For one end user of your product, `miosa api-key scoped` mints a key bound to that
person instead of the organization.

`env:reveal` is separate from `env:read` on purpose: a key that lists variables
cannot read their values. Keep it off keys that do not need it, and never put a
key in a client-side bundle.

# Audit Log

URL: https://miosa.ai/docs/security/audit-log
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security/audit-log
Source: src/routes/docs/security/audit-log/+page.md
Description: Egress audit log for outbound calls: rows, live tail, filters and export. Capture is not yet enabled in the current release.

# Audit Log

When egress audit capture is enabled, every outbound call from your sandbox is recorded automatically with no setup, and the Audit Log tab on each sandbox/computer is where you read it. Egress audit capture is not yet enabled in the current release, so the tab can be empty until the egress audit pipeline ships.

The egress audit log surface exists, but capture is not yet wired in the current release. Do not rely on it as the only record of network activity yet.

## What's in each row

| Column | Description |
|---|---|
| `timestamp` | When the request happened (microsecond precision) |
| `host` | Upstream hostname |
| `method` | GET, POST, PUT, … |
| `path` | URL path (query string redacted) |
| `action` | `allow`, `reject`, `stub`, `error`, `client_cancel` |
| `status_code` | Upstream response code (or 0 if no response) |
| `duration_ms` | Wall-clock time |
| `bytes_in` / `bytes_out` | Volume |
| `request_transforms` | Which transforms fired (secrets, allowlist, header allowlist, …) |
| `mcp` | MCP message trace, when the call was an MCP JSON-RPC request |

## Live tail

The Audit Log tab streams new events in real time over WebSocket. New rows appear at the top as your sandbox makes calls.

## Filtering

In the UI, use the filter bar to scope by:

- **Time range**  -  last hour, 24h, 7d, 30d, custom
- **Host**  -  exact or wildcard
- **HTTP method**
- **Action**  -  show only blocked, only allowed, only errors
- **Transform**  -  show only requests that swapped a particular secret, or only MCP tool calls
- **Status code**  -  show only 4xx, only 5xx, etc.

All filters are URL-shareable.

## From the SDK

```python
# List recent events
events = sandbox.audit.list(
    since="1h",
    host="api.openai.com",
    action="allow",
    limit=100,
)

for e in events:
    print(e.timestamp, e.host, e.method, e.status_code, e.duration_ms)

# Live tail (blocks; yields events as they arrive)
for event in sandbox.audit.tail():
    print(event.host, event.action)
    if event.action == "reject":
        break

# Tenant-wide audit (admin-scoped key required)

## Common queries

### "Why did this fail?"
Filter by `action=reject` for the last hour. Each row tells you which rule blocked it (`rejected_by` column).

### "Which secret did this request use?"
Each row's `request_transforms` JSON includes a `secrets` entry listing the secret names swapped. UI surfaces this in the detail drawer; SDK exposes it as `event.request_transforms.secrets.swapped`.

### "What did our AI agent do last quarter?"
Tenant-admin filter by date range and resource type. Export CSV.

### "Show me all calls by Dana"
For white-label deployments, filter by `external_user_id`. See [White-label Credentials](/docs/security/white-label).

## Export

Every filtered view can be exported as CSV or JSON via the "Export" button (UI) or the SDK:

```python
sandbox.audit.export(since="30d", format="csv", path="audit-30d.csv")
```

## Retention

| Plan | Retention |
|---|---|
| All plans (default) | 90 days |
| Custom retention (longer) | available on enterprise plans |

Beyond the retention window, rows are deleted from `egress_audit`. Export your data if you need a longer record.

If you delete a sandbox, its audit rows remain in the tenant's audit table for the retention window. Identity columns (tenant, workspace, user, external_*) are denormalized at write time so queries don't need joins.

## Programmatic alerting (Phase 5)

You'll be able to wire saved queries into alerting:

> "Notify me if any sandbox makes more than 100 requests to a never-before-seen host in 5 minutes."

This ships in Phase 5 of the Security rollout.

## Real-world example  -  compliance dashboard for a multi-tenant SaaS

You're building a SaaS where each end user runs in their own sandbox. Compliance requires you to surface all outbound calls per user in your own dashboard, with a 30-day export.

```python

from miosa import Miosa
from datetime import datetime

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

def get_member_report(member_id: str, days: int = 30) -> dict:
    """Return an audit summary for one member over the last N days."""
    events = client.audit.list(
        since=f"{days}d",
        external_user_id=member_id,
        limit=1000,
    )

    hosts = {}
    blocked = []
    for e in events:
        hosts[e.host] = hosts.get(e.host, 0) + 1
        if e.action == "reject":
            blocked.append({
                "timestamp": e.timestamp,
                "host": e.host,
                "method": e.method,
                "rule": e.rejected_by,
            })

    return {
        "member_id": member_id,
        "period_days": days,
        "total_requests": len(events),
        "unique_hosts": len(hosts),
        "top_hosts": sorted(hosts.items(), key=lambda x: -x[1])[:10],
        "blocked_count": len(blocked),
        "blocked_events": blocked[:20],
    }

report = get_member_report("dana@example.net", days=30)
print(json.dumps(report, indent=2))

# Export to CSV
client.audit.export(
    since="30d",
    format="csv",
    path=f"audit-dana-30d.csv",
    external_user_id="dana@example.net",
)
print("Exported audit-dana-30d.csv")
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

async function getMemberReport(memberId: string, days = 30) {
  const events = await client.audit.list({
    since: `${days}d`,
    externalUserId: memberId,
    limit: 1000,
  });

  const hosts: Record<string, number> = {};
  const blocked = [];

  for (const e of events) {
    hosts[e.host] = (hosts[e.host] ?? 0) + 1;
    if (e.action === 'reject') {
      blocked.push({ timestamp: e.timestamp, host: e.host, rule: e.rejectedBy });
    }
  }

  return {
    memberId,
    periodDays: days,
    totalRequests: events.length,
    uniqueHosts: Object.keys(hosts).length,
    topHosts: Object.entries(hosts).sort(([, a], [, b]) => b - a).slice(0, 10),
    blockedCount: blocked.length,
    blockedEvents: blocked.slice(0, 20),
  };
}

const report = await getMemberReport('dana@example.net', 30);
console.log(JSON.stringify(report, null, 2));

await client.audit.export({
  since: '30d',
  format: 'csv',
  path: 'audit-dana-30d.csv',
  externalUserId: 'dana@example.net',
});
```

## Troubleshooting

**Audit log is empty even though the sandbox is running.**
The audit log only records *outbound* calls from the sandbox. If the sandbox is just waiting for input or doing in-process computation with no network calls, no rows appear. Trigger an outbound call and re-query.

**`audit.tail()` disconnects after a few seconds.**
Tail connections are kept alive with WebSocket pings. If your network has a short idle-connection timeout, the connection can drop. Reconnect in your retry loop:

```python
while True:
    try:
        for event in sandbox.audit.tail():
            process(event)
    except ConnectionError:
        time.sleep(1)  # reconnect
```

**`request_transforms.secrets.swapped` is empty  -  but I have secrets bound.**
If the sandbox's env var contains the real key (e.g., from a `.env` file that overrode the placeholder), the proxy has nothing to swap. Run `sandbox.exec("echo $OPENAI_API_KEY")`  -  if it prints the real `sk-proj-...` instead of `miosa-tok-...`, the `.env` file is winning.

**Tenant-wide `client.audit.list()` returns too many rows.**
Narrow with `external_user_id`, `external_workspace_id`, `host`, or `action` filters. Maximum `limit` per call is 1000. For larger exports, use `audit.export()`.

**I need audit rows older than 90 days.**
Default retention is 90 days. For longer retention, contact support to enable custom retention on your tenant. Export regularly if you need a permanent archive.

For more issues, see the [Security troubleshooting hub](/docs/security/troubleshooting).

## Frequently asked

**Does the audit log capture request bodies?**
Not by default  -  only headers (redacted) and metadata. You can opt in to body capture per-resource if you need it for compliance, with a "may contain sensitive data" warning.

**Are response bodies captured?**
No. Audit is request-side only.

**Can I disable the audit log entirely?**
No  -  audit is the platform baseline. You can shorten retention but not disable it.

**Will live-tail consume my plan's API quota?**
No. Audit streaming is over a WebSocket and doesn't count against REST API rate limits.

# Connect Accounts (OAuth)

URL: https://miosa.ai/docs/security/connect-accounts
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security/connect-accounts
Source: src/routes/docs/security/connect-accounts/+page.md
Description: Authorize accounts (GitHub, Google, Slack, …) once. MIOSA manages token refresh; your sandbox sees an env var.

# Connect Accounts (OAuth)

Instead of pasting a personal-access token or API key, **authorize an account** directly with the upstream provider. MIOSA stores the access + refresh tokens, refreshes them in the background, and exposes the current valid access token to your sandbox as a plain environment variable.

## When to use this over Secrets

| You have… | Use |
|---|---|
| An API key string (e.g., OpenAI `sk-…`, Stripe `sk_live_…`) | [Secrets](/docs/security/secrets) |
| An account where the provider supports OAuth (GitHub, Google, Slack, …) | **Connect Accounts** |
| A machine-to-machine OAuth2 client (client_id + client_secret) | **Connect Accounts** (Machine OAuth) |

## Connect a GitHub account (the typical flow)

### From the dashboard

```
1. Sandbox detail → Secrets tab → "+ Connect Account"
2. Pick "GitHub" from the provider grid
3. Browser opens to github.com/login/oauth/authorize
4. Approve the scopes you want to grant
5. You bounce back to MIOSA. Done.
```

A new entry appears in your Secrets list:

```
Name:     github_token
Type:     OAuth Connect
Provider: GitHub
Scopes:   repo, read:user
Expires:  in 8 hours (auto-refreshed)
```

Inside your sandbox:

```bash
$ echo $GITHUB_TOKEN
miosa-tok-9a3c5e7b1f8d2a4c...
```

Use it exactly like a real token  -  the swap happens on egress:

```python
requests.get(
    "https://api.github.com/user/repos",
    headers={"Authorization": f"Bearer {os.environ['GITHUB_TOKEN']}"},
)
```

When the access token expires, MIOSA uses the refresh token in the background to mint a new one. Your code never notices.

### From the SDK

```python
flow = sandbox.secrets.connect(
    provider="github",
    expose_as_env="GITHUB_TOKEN",
)

# `flow.authorize_url` is a URL the end user opens in their browser.
print("Authorize at:", flow.authorize_url)

# Block until the user completes the OAuth dance:
flow.wait_for_completion(timeout=300)
```

```ts
const flow = await sandbox.secrets.connect({
  provider: 'github',
  exposeAsEnv: 'GITHUB_TOKEN',
});

console.log('Authorize at:', flow.authorizeUrl);
await flow.waitForCompletion({ timeoutSec: 300 });
```

```go
flow, err := sandbox.Secrets.Connect(ctx, miosa.OAuthConnect{
    Provider:    "github",
    ExposeAsEnv: "GITHUB_TOKEN",
    Scopes:      []string{"repo", "read:user"},
})
if err != nil { panic(err) }

fmt.Println("Authorize at:", flow.AuthorizeURL)
if err := flow.WaitForCompletion(ctx, 300); err != nil { panic(err) }
```

```java
OAuthFlow flow = sandbox.secrets().connect(OAuthConnect.builder()
    .provider("github")
    .exposeAsEnv("GITHUB_TOKEN")
    .scopes(List.of("repo", "read:user"))
    .build());

System.out.println("Authorize at: " + flow.getAuthorizeUrl());
flow.waitForCompletion(Duration.ofSeconds(300));
```

```elixir
{:ok, flow} = Miosa.Secrets.connect(sandbox.id, %{
  provider: "github",
  expose_as_env: "GITHUB_TOKEN",
  scopes: ["repo", "read:user"]
})

IO.puts("Authorize at: #{flow.authorize_url}")
{:ok, _} = Miosa.Secrets.wait_for_oauth(flow.id, timeout: 300)
```

## Supported providers

| Provider | Status |
|---|---|
| GitHub | ✅ available |
| Google (Gmail, Drive, Calendar) | rolling out |
| Slack | rolling out |
| Linear | rolling out |
| Notion | rolling out |
| Stripe | planned |
| HubSpot | planned |
| Custom OAuth2 provider | planned  -  file a request |

Adding a new well-known provider is a config-only change on our side  -  no SDK release needed.

## Machine OAuth (client credentials)

For provider APIs that use the OAuth2 client-credentials flow (no end-user, machine-to-machine):

```python
sandbox.secrets.add_machine_oauth(
    name="my_internal_api",
    client_id="abc...",
    client_secret="def...",
    token_url="https://my-api.example.com/oauth/token",
    scopes=["read", "write"],
    expose_as_env="INTERNAL_API_TOKEN",
)
```

MIOSA mints + caches access tokens against `token_url`, refreshes ahead of expiry, and injects them as `INTERNAL_API_TOKEN`.

## What the proxy injects

For an OAuth Connect secret, the proxy injects:

- **Access token** by default (the most common case  -  `Authorization: Bearer …`)
- **Refresh-on-401**: if the upstream returns a 401, the proxy attempts a refresh before bubbling the error to your code

The refresh token itself is **never** exposed to the sandbox. It stays encrypted in MIOSA's vault.

## Rotation, revocation, scope changes

- **Rotation**: happens automatically. You don't do anything.
- **Revocation**: open the Secrets tab → click "Disconnect" → MIOSA destroys the refresh token immediately. The next outbound request fails with 401.
- **Scope changes**: requires re-authorizing. Click "Re-authorize" on the secret; you'll go through the OAuth dance again with the new scopes.

## White-label OAuth (your branding, not MIOSA's)

By default, end-users see "Authorize MIOSA to access your GitHub" in the OAuth consent screen. For white-label deployments, register your own OAuth app and route the dance through your branding  -  see [White-label Credentials](/docs/security/white-label).

## Real-world example  -  agent reads GitHub issues and posts Slack updates

Connect both GitHub and Slack via OAuth. The agent reads open issues and posts a daily digest to a Slack channel. No credentials ever enter the sandbox.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])
sandbox = client.sandboxes.create(template_id="python-ds")

# Connect GitHub
github_flow = sandbox.secrets.connect(
    provider="github",
    expose_as_env="GITHUB_TOKEN",
    scopes=["repo", "read:user"],
)
print("1. Authorize GitHub at:", github_flow.authorize_url)
github_flow.wait_for_completion(timeout=300)
print("   GitHub connected.")

# Connect Slack
slack_flow = sandbox.secrets.connect(
    provider="slack",
    expose_as_env="SLACK_BOT_TOKEN",
    scopes=["chat:write", "channels:read"],
)
print("2. Authorize Slack at:", slack_flow.authorize_url)
slack_flow.wait_for_completion(timeout=300)
print("   Slack connected.")

# Write and run the agent
agent_code = '''

GITHUB_TOKEN = os.environ["GITHUB_TOKEN"]
SLACK_TOKEN  = os.environ["SLACK_BOT_TOKEN"]
REPO         = "your-org/your-repo"
CHANNEL      = "#engineering-digest"

# Fetch open issues
issues = requests.get(
    f"https://api.github.com/repos/{REPO}/issues?state=open&per_page=10",
    headers={"Authorization": f"Bearer {GITHUB_TOKEN}"},
).json()

# Build digest message
lines = [f"*Open issues digest for {REPO}*"]
for i in issues:
    lines.append(f"• <{i['html_url']}|#{i['number']} {i['title']}>")
message = "\\n".join(lines)

# Post to Slack
resp = requests.post(
    "https://slack.com/api/chat.postMessage",
    headers={"Authorization": f"Bearer {SLACK_TOKEN}"},
    json={"channel": CHANNEL, "text": message},
)
print("Posted:", resp.json().get("ok"))
'''

sandbox.files.write("/workspace/digest.py", agent_code)
result = sandbox.exec("python /workspace/digest.py")
print(result.stdout)
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
const sandbox = await client.sandboxes.create({ template: 'node-web' });

// Connect GitHub
const githubFlow = await sandbox.secrets.connect({
  provider: 'github',
  exposeAsEnv: 'GITHUB_TOKEN',
  scopes: ['repo', 'read:user'],
});
console.log('1. Authorize GitHub at:', githubFlow.authorizeUrl);
await githubFlow.waitForCompletion({ timeoutSec: 300 });
console.log('   GitHub connected.');

// Connect Slack
const slackFlow = await sandbox.secrets.connect({
  provider: 'slack',
  exposeAsEnv: 'SLACK_BOT_TOKEN',
  scopes: ['chat:write', 'channels:read'],
});
console.log('2. Authorize Slack at:', slackFlow.authorizeUrl);
await slackFlow.waitForCompletion({ timeoutSec: 300 });
console.log('   Slack connected.');

// Run the digest agent
const result = await sandbox.exec('node /workspace/digest.js');
console.log(result.stdout);
```

## Troubleshooting

**`flow.wait_for_completion` times out  -  user authorized but the flow never resolves.**
Usually means the OAuth callback URL is wrong. Verify the callback URL in your OAuth app settings on the provider side matches what MIOSA expects. For white-label setups, make sure your proxy endpoint is forwarding `code` and `state` parameters to `client.oauth.complete()`.

**GitHub OAuth returns "bad_verification_code".**
The authorization code is single-use with a short TTL (10 minutes for GitHub). If `wait_for_completion` took too long, or the callback was called twice, the code is stale. Re-initiate `sandbox.secrets.connect()` to get a fresh flow.

**Token expired  -  sandbox gets 401 from GitHub.**
MIOSA auto-refreshes tokens. If refresh fails (token revoked by user), the dashboard shows "Reconnect needed." Call `sandbox.secrets.reauthorize(provider="github")` and have the user re-authorize.

**"invalid_grant" during token refresh.**
GitHub (and most providers) invalidate the refresh token when the user revokes the OAuth app permission. Re-connect via `sandbox.secrets.reauthorize()`.

**Slack posts succeed but the token appears in the message body.**
This happens if the Slack SDK puts the token in the request body instead of the `Authorization` header. The MIOSA proxy scans bodies when buffered, but Slack's standard `Bearer` header is the reliable path. Ensure you're using `Authorization: Bearer $SLACK_BOT_TOKEN`.

For more issues, see the [Security troubleshooting hub](/docs/security/troubleshooting).

## Frequently asked

**My OAuth provider isn't on the list. Can I add it manually?**
Yes  -  file a request, or use the Custom OAuth2 path when it ships (Phase 3). For now, any provider that issues static access tokens works as a regular API key via [Secrets](/docs/security/secrets).

**Does the sandbox see the refresh token?**
No. Only the current access token is injected. Refresh tokens stay encrypted in MIOSA.

**Can I bind one OAuth account to many sandboxes?**
Yes. Save the secret at the `tenant`, `workspace`, or `user` scope; every sandbox in that scope inherits the binding.

**What happens if the provider revokes my token from their side?**
The proxy's next refresh attempt will fail. We surface this in the dashboard with a "Reconnect needed" badge on the secret, and your next outbound request returns 401.

# Network Allowlist

URL: https://miosa.ai/docs/security/network
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security/network
Source: src/routes/docs/security/network/+page.md
Description: Watch what your sandbox calls. When you're ready, lock it down with a one-click allowlist. Reversible.

# Network Allowlist

By default, every new MIOSA sandbox is configured in **audit-only mode**: outbound calls are not blocked. Audit-only mode logs every outbound request, so you can see which hosts your sandbox calls before you lock down.

Lockdown is never applied automatically. You explicitly click "Lock Down"  -  and you can revert to audit-only at any time with one click. No data is lost in either direction.

## The two modes

| Mode | What it does | Default? |
|---|---|---|
| **Audit-only** | Logs every outbound request; nothing is blocked. | ✅ yes  -  every new sandbox starts here |
| **Enforce** | Applies the allowlist. Requests to unlisted hosts are blocked. | opt-in |

## The "watch then enforce" flow

### Day 0  -  Sandbox is created

No setup. Audit-only is on by default. Your sandbox makes outbound calls exactly like it did before MIOSA Egress existed. Outbound calls are logged, and the hosts they reach build your allowlist.

### Day 0-7  -  Use your sandbox normally

Build, deploy, run your agent  -  whatever. MIOSA collects audit data.

### Day 7+  -  Visit the Network tab

The Network tab shows you:

```
HOSTS CONTACTED IN THE LAST 7 DAYS                  REQUESTS

api.openai.com                                        1,247
*.anthropic.com                                          83
github.com                                               412
pypi.org                                                  29
files.pythonhosted.org                                   161
api.github.com                                          1,053
```

Click "Lock Down". A confirmation modal appears showing the checkboxes for each host. You uncheck anything you don't want. Click Confirm.

Mode flips to **enforce**. The proxy now blocks anything not on the list.

### After lockdown  -  New hosts go to Pending

If your sandbox tries to reach a host that isn't on the allowlist, the request is blocked AND the host appears in the **Pending Requests** section of the Network tab. One click → Allow or Block.

You're never stuck  -  denied requests are visible, attributable, and one click away from resolution.

## SDK  -  Network controls

```python
# Allow a host (audit-only or enforce  -  doesn't matter; allow is allow)
sandbox.network.allow("api.openai.com")
sandbox.network.allow("*.anthropic.com", methods=["POST"])

# Explicit deny  -  overrides any allow
sandbox.network.deny("169.254.169.254")

# Switch to enforce mode using the current allowlist
sandbox.network.lockdown()

# Switch back to audit-only
sandbox.network.observe()

# Auto-suggested allowlist from observed traffic
hosts = sandbox.network.suggestions(since="7d")
for h in hosts:
    print(h.host, h.request_count, h.last_seen)

# Inspect the current policy
policy = sandbox.network.get_policy()
print(policy.mode, policy.allow_rules, policy.deny_rules)

# Pending blocked requests
pending = sandbox.network.pending()
for p in pending:
    print(p.host, p.request_count, "blocked")
```

```typescript
await sandbox.network.allow('api.openai.com');
await sandbox.network.allow('*.anthropic.com', { methods: ['POST'] });
await sandbox.network.deny('169.254.169.254');
await sandbox.network.lockdown();
await sandbox.network.observe();

const hosts = await sandbox.network.suggestions({ since: '7d' });
const policy = await sandbox.network.getPolicy();
const pending = await sandbox.network.pending();
```

```go
sandbox.Network.Allow(ctx, "api.openai.com", miosa.AllowOpts{})
sandbox.Network.Allow(ctx, "*.anthropic.com", miosa.AllowOpts{Methods: []string{"POST"}})
sandbox.Network.Deny(ctx, "169.254.169.254")
sandbox.Network.Lockdown(ctx)
sandbox.Network.Observe(ctx)

hosts, _ := sandbox.Network.Suggestions(ctx, miosa.SuggestionsOpts{Since: "7d"})
policy, _ := sandbox.Network.GetPolicy(ctx)
pending, _ := sandbox.Network.Pending(ctx)
```

```java
sandbox.network().allow("api.openai.com");
sandbox.network().allow("*.anthropic.com", AllowOpts.builder().methods(List.of("POST")).build());
sandbox.network().deny("169.254.169.254");
sandbox.network().lockdown();
sandbox.network().observe();

List hosts = sandbox.network().suggestions(
    SuggestionsOpts.builder().since("7d").build());
NetworkPolicy policy = sandbox.network().getPolicy();
List pending = sandbox.network().pending();
```

```elixir
{:ok, _} = Miosa.Network.allow(sandbox.id, "api.openai.com")
{:ok, _} = Miosa.Network.allow(sandbox.id, "*.anthropic.com", methods: ["POST"])
{:ok, _} = Miosa.Network.deny(sandbox.id, "169.254.169.254")
{:ok, _} = Miosa.Network.lockdown(sandbox.id)
{:ok, _} = Miosa.Network.observe(sandbox.id)

{:ok, hosts}   = Miosa.Network.suggestions(sandbox.id, since: "7d")
{:ok, policy}  = Miosa.Network.get_policy(sandbox.id)
{:ok, pending} = Miosa.Network.pending(sandbox.id)
```

## Pattern matching

| Kind | Example | Matches |
|---|---|---|
| Exact host | `api.openai.com` | only this hostname |
| Wildcard | `*.openai.com` | any subdomain of openai.com |
| CIDR (IP only) | `10.0.0.0/8` | any IP in this range, only when the request target is an IP literal (not a hostname) |

Precedence at request time:

1. Exact match wins over wildcard
2. Wildcard wins over CIDR
3. Explicit `deny` rules always win over `allow`

## Per-resource vs tenant-wide rules

You can attach allowlist rules at two levels:

- **Per-resource**  -  applies to just one sandbox or computer
- **Tenant-wide**  -  applies to every resource in your tenant unless a resource has its own override

This means you can have a tenant default of "only allow our internal API + npm" and per-sandbox additions on top.

## When to use warn-mode rules

You can mark a rule as `warn_only`:

```python
sandbox.network.allow("api.experimental.example.com", warn_only=True)
```

In enforce mode, a `warn_only` allow rule still lets the request through but flags it in the audit log. Useful for trial-running a new third-party integration before committing to it.

## Rolling back

If lockdown breaks something:

```python
sandbox.network.observe()
```

You're back to audit-only. Allowlist rules are preserved (so you can re-lockdown later) but they're no longer enforcing.

## Real-world example  -  Python data pipeline locked to its upstream services

A Python sandbox that fetches data from a REST API, processes it, and writes results to an S3-compatible endpoint. Locked down to exactly those three hosts.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])
sandbox = client.sandboxes.create(template_id="python-ds")

# Store credentials in the vault
sandbox.secrets.set(name="data_api_key", value=os.environ["DATA_API_KEY"], expose_as_env="DATA_API_KEY")
sandbox.secrets.set(name="s3_key", value=os.environ["S3_SECRET_KEY"], expose_as_env="AWS_SECRET_ACCESS_KEY")

# Let it run for a minute to observe traffic

pipeline = """

resp = requests.get(
    "https://data.example.com/api/v1/events?limit=100",
    headers={"X-Api-Key": os.environ["DATA_API_KEY"]},
)
events = resp.json()

# Process…
summary = {"count": len(events), "total_value": sum(e["value"] for e in events)}

s3 = boto3.client(
    "s3",
    endpoint_url="https://storage.example.com",
    aws_access_key_id="access",
    aws_secret_access_key=os.environ["AWS_SECRET_ACCESS_KEY"],
)

s3.put_object(Bucket="results", Key="summary.json", Body=json.dumps(summary))
print("Done:", summary)
"""
sandbox.files.write("/workspace/pipeline.py", pipeline)
sandbox.exec("pip install boto3 -q")
sandbox.exec("python /workspace/pipeline.py")   # observe this run

# Now lock down based on what we observed
suggestions = sandbox.network.suggestions(since="1h")
print("Observed hosts:")
for h in suggestions:
    print(f"  {h.host} ({h.request_count} requests)")

# Allow only the three we expect
sandbox.network.allow("data.example.com")
sandbox.network.allow("storage.example.com")
sandbox.network.allow("pypi.org")          # for the pip install above
sandbox.network.allow("files.pythonhosted.org")
sandbox.network.lockdown()
print("Locked. Mode:", sandbox.network.get_policy().mode)

# Run again  -  still works, nothing else reachable
result = sandbox.exec("python /workspace/pipeline.py")
print(result.stdout)
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
const sandbox = await client.sandboxes.create({ template: 'python-ds' });

await sandbox.secrets.set({ name: 'data_api_key', value: process.env.DATA_API_KEY!, exposeAsEnv: 'DATA_API_KEY' });

// Observe one run, then lock down
const suggestions = await sandbox.network.suggestions({ since: '1h' });
for (const h of suggestions) {
  await sandbox.network.allow(h.host);
}
await sandbox.network.lockdown();
console.log('Locked to:', suggestions.map(h => h.host).join(', '));
```

## Reuse a policy across sandboxes

Export a locked policy and apply it to a new sandbox:

```python
# Export the policy from a locked sandbox
policy = sandbox.network.get_policy()

# Apply it to a new sandbox
new_sandbox = client.sandboxes.create(template_id="python-ds")
for rule in policy.allow_rules:
    new_sandbox.network.allow(rule.host, methods=rule.methods)
for rule in policy.deny_rules:
    new_sandbox.network.deny(rule.host)
new_sandbox.network.lockdown()
print(f"Policy cloned to {new_sandbox.id}.")
```

For the same policy on every new sandbox, apply rules at the tenant level with `client.network.allow(...)` and `client.network.lockdown()`; they become the default for all resources unless a sandbox overrides them.

A sandbox created from a template inherits the template's network policy. If the template was snapshotted in enforce mode, new sandboxes start locked down. Call `new_sandbox.network.observe()` right after create to return it to audit-only.

## Full script

End-to-end: observe, review, lock down, and check the pending queue.

```python
#!/usr/bin/env python3
"""lockdown_workflow.py  -  audit-only to enforce in one pass"""

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])
sandbox = client.sandboxes.create(template_id="python-ds")
print(f"Sandbox {sandbox.id}  -  mode: {sandbox.network.get_policy().mode}")

# 1. Observe (use 7d in production)
time.sleep(10)

# 2. Review observed hosts
suggestions = sandbox.network.suggestions(since="1h")
for h in suggestions:
    print(f"  {h.host}  ({h.request_count} requests)")

# 3. Lock down with the observed hosts as the allowlist
for h in suggestions:
    sandbox.network.allow(h.host)
sandbox.network.lockdown()
print(f"Locked. Mode: {sandbox.network.get_policy().mode}")

# 4. Check what is still being blocked
pending = sandbox.network.pending()
for p in pending:
    print(f"  {p.host}  ({p.request_count} blocked)")
```

## Troubleshooting

**`pip install` fails after lockdown  -  "Could not find a version that satisfies the requirement".**
Three domains are needed: `pypi.org`, `files.pythonhosted.org`, and `pythonhosted.org`. Allow all three before locking down.

**An agent stopped working after lockdown and I cannot tell what is blocked.**
Open the Network tab -> Pending Requests, or call `sandbox.network.pending()`. Each blocked row has a `rejected_by` field naming the rule that fired.

**`npm install` fails after lockdown.**
Allow `registry.npmjs.org`. Some packages also fetch from `*.github.com` during postinstall scripts  -  check the Pending queue for exact hosts.

**My sandbox is in enforce mode but I see unexpected hosts in the audit log.**
Audit-only log entries always appear even in enforce mode (blocked calls still get logged with `action=reject`). Filter by `action=reject` to see what's being blocked.

**I want the same policy on every new sandbox without configuring each one.**
Apply rules at the tenant level using `client.network.allow(...)` and `client.network.lockdown()`  -  these become the default for all resources in the tenant unless overridden per sandbox.

**After `observe()`, my rules are gone when I call `lockdown()` again.**
Rules are never deleted by `observe()`. If they appear missing, check `sandbox.network.get_policy().allow_rules`  -  they'll be listed there. The only way rules disappear is if you called `sandbox.network.clear_rules()` explicitly.

For more issues, see the [Security troubleshooting hub](/docs/security/troubleshooting).

## Frequently asked

**Will lockdown block npm install or pip install?**
Only if you don't allow `pypi.org`, `files.pythonhosted.org`, `registry.npmjs.org`, etc. The 7-day audit data will have already shown you these  -  they're on the suggested list.

**My agent suddenly stopped working after I locked down.**
Open the Network tab → Pending Requests. You'll see exactly what got blocked. One-click allow, or revert with `observe()`.

**Can I share allowlists across sandboxes?**
Yes  -  apply them at the tenant or workspace scope, or copy a "policy template" from another resource (Phase 5).

**Does lockdown affect inbound (preview) traffic?**
No. Lockdown is for outbound only. Preview URLs into your sandbox keep working exactly as before.

# Secrets  -  Quickstart

URL: https://miosa.ai/docs/security/secrets
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security/secrets
Source: src/routes/docs/security/secrets/+page.md
Description: Store API keys in MIOSA. Your sandbox uses an opaque placeholder. The real key never lives inside the VM.

# Secrets  -  Quickstart

Store an API key once in MIOSA. Every sandbox using it sees an opaque placeholder env var. Rotate in one place, every sandbox picks up the new value automatically.

## Add an API key (30 seconds)

### From the dashboard

```
1. Open your Sandbox or Computer in the MIOSA dashboard
2. Click the "Secrets" tab
3. Click "+ Add Secret"
4. Fill in:
     Name:        openai_key
     Value:       sk-proj-...  (paste your real key)
     Expose as:   OPENAI_API_KEY
5. Save
```

Inside the sandbox, `process.env.OPENAI_API_KEY` is now an opaque token. Use it in your code exactly as you would the real key  -  the swap happens on egress.

### From the SDK

```python
from miosa import Miosa
client = Miosa(api_key="msk_u_...")
sandbox = client.sandboxes.create(template_id="python-ds")

sandbox.secrets.set(
    name="openai_key",
    value="sk-proj-...",
    expose_as_env="OPENAI_API_KEY",
)
```

```ts

const miosa = new Miosa({ apiKey: 'msk_u_...' });
const sandbox = await miosa.sandboxes.create({ template: 'node-web' });

await sandbox.secrets.set({
  name: 'openai_key',
  value: process.env.MY_OPENAI_KEY!,
  exposeAsEnv: 'OPENAI_API_KEY',
});
```

```go
client := miosa.NewClient(os.Getenv("MIOSA_API_KEY"))
sandbox, _ := client.Sandboxes.Create(ctx, miosa.SandboxCreate{Template: "go-web"})

sandbox.Secrets.Set(ctx, miosa.SecretSet{
    Name:         "openai_key",
    Value:        realKey,
    ExposeAsEnv:  "OPENAI_API_KEY",
})
```

## How the placeholder works

Inside the sandbox after binding:

```bash
$ echo $OPENAI_API_KEY
miosa-tok-7f2a8c1d4b2e6f0a...
```

When your code makes an outbound call:

```python
requests.post(
    "https://api.openai.com/v1/chat/completions",
    headers={"Authorization": f"Bearer {os.environ['OPENAI_API_KEY']}"},
    json={...},
)
```

…the MIOSA proxy on your VM's host sees the request, finds `miosa-tok-7f2a8c1d4b2e6f0a` in the `Authorization` header, and **swaps it with your real `sk-proj-...`** before forwarding to OpenAI. OpenAI sees the real key. Your sandbox never did.

The placeholder is unique per binding  -  there is no global table of placeholders an attacker could brute-force.

Header values, query parameters, URL paths, and (when buffered) request bodies are all scanned for placeholder tokens. Basic-auth headers are decoded → swapped → re-encoded.

## Rotate a key

```python
sandbox.secrets.rotate("openai_key", new_value="sk-proj-newvalue...")
```

Every sandbox using this secret picks up the new value on its next outbound request. No restart. No redeploy. The placeholder token doesn't change.

## List + delete

```python
secrets = sandbox.secrets.list()
# Returns metadata only  -  name, type, preview (last 4 chars), last_used_at.
# Never returns the real value.

sandbox.secrets.delete("openai_key")
```

## Scope levels

A secret can be scoped at five levels  -  the proxy picks the most specific match for the resource making the request:

| Scope | Use case |
|---|---|
| `tenant` | Your organization's company-wide credentials |
| `workspace` | Credentials shared by everyone in one workspace |
| `user` | An individual MIOSA user's personal credentials |
| `external_user` | A white-label end-user's credentials (see [White-label](/docs/security/white-label)) |
| `external_workspace` | A white-label workspace's credentials |

Default scope when using `sandbox.secrets.set` is determined by the API key making the call. Tenant admins can create tenant-wide secrets; individual users create user-scoped ones for their own resources.

## Runtime profiles vs secrets

Agent runtime profiles and secrets solve different problems.

| Configuration | Put it in | Example |
|---|---|---|
| Non-secret runtime defaults | Agent runtime profile `env` | `ANTHROPIC_MODEL=claude-sonnet-4.6` |
| Provider API keys | Managed secret or connector | `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, `HIGGSFIELD_API_KEY` |
| Tool catalog | Agent runtime profile `tools` | `filesystem`, `shell`, `browser`, `refero` |
| Account connection | Connector binding | GitHub org, Slack workspace, CRM tenant |
| Per-run override | Agent run `env` | `FEATURE_FLAG=on` |

For white-label products, use this hierarchy:

```text
Tenant default
  -> workspace default
    -> project or resource binding
      -> sandbox/computer runtime
        -> run-level override
```

A Lumen-style platform can set an Anthropic key once for a customer workspace. Every
sandbox or computer launched in that workspace can receive the right placeholder
or connector token automatically, while the runtime profile chooses which agent
harness and tools are enabled.

Do not store long-lived provider secrets in runtime profile `env`. Profiles are
for defaults and policy. Secrets and connectors are for credentials.

## What the proxy can do beyond a string swap

For OAuth-managed credentials (see [Connect Accounts](/docs/security/connect-accounts)), the proxy also:

- **Refreshes expired tokens** automatically using the stored refresh token
- **Surfaces token revocation** (when the upstream side invalidates the access) as a 401 to your code, exactly as if you'd held the token yourself

You don't write any of that logic.

## All 5 SDKs

```python
from miosa import Miosa
client = Miosa(api_key="msk_u_...")
sandbox = client.sandboxes.create(template_id="python-ds")

sandbox.secrets.set(
    name="openai_key",
    value="sk-proj-...",
    expose_as_env="OPENAI_API_KEY",
)
sandbox.secrets.rotate("openai_key", new_value="sk-proj-newvalue...")
secrets = sandbox.secrets.list()
sandbox.secrets.delete("openai_key")
```

```typescript

const miosa = new Miosa({ apiKey: 'msk_u_...' });
const sandbox = await miosa.sandboxes.create({ template: 'node-web' });

await sandbox.secrets.set({
  name: 'openai_key',
  value: process.env.MY_OPENAI_KEY!,
  exposeAsEnv: 'OPENAI_API_KEY',
});
await sandbox.secrets.rotate({ name: 'openai_key', newValue: 'sk-proj-newvalue...' });
const secrets = await sandbox.secrets.list();
await sandbox.secrets.delete('openai_key');
```

```go
client := miosa.NewClient(os.Getenv("MIOSA_API_KEY"))
sandbox, _ := client.Sandboxes.Create(ctx, miosa.SandboxCreate{Template: "go-web"})

sandbox.Secrets.Set(ctx, miosa.SecretSet{
    Name:        "openai_key",
    Value:       realKey,
    ExposeAsEnv: "OPENAI_API_KEY",
})
sandbox.Secrets.Rotate(ctx, "openai_key", "sk-proj-newvalue...")
secrets, _ := sandbox.Secrets.List(ctx)
sandbox.Secrets.Delete(ctx, "openai_key")
```

```java
MiosaClient client = new MiosaClient(System.getenv("MIOSA_API_KEY"));
Sandbox sandbox = client.sandboxes().create(SandboxCreate.builder()
    .template("python-ds").build());

sandbox.secrets().set(SecretSet.builder()
    .name("openai_key")
    .value(System.getenv("MY_OPENAI_KEY"))
    .exposeAsEnv("OPENAI_API_KEY")
    .build());
sandbox.secrets().rotate("openai_key", "sk-proj-newvalue...");
List secrets = sandbox.secrets().list();
sandbox.secrets().delete("openai_key");
```

```elixir
{:ok, sandbox} = Miosa.Sandboxes.create(%{template_id: "python-ds"})

{:ok, _} = Miosa.Secrets.set(sandbox.id, %{
  name: "openai_key",
  value: System.get_env("MY_OPENAI_KEY"),
  expose_as_env: "OPENAI_API_KEY"
})
{:ok, _} = Miosa.Secrets.rotate(sandbox.id, "openai_key", "sk-proj-newvalue...")
{:ok, secrets} = Miosa.Secrets.list(sandbox.id)
{:ok, _} = Miosa.Secrets.delete(sandbox.id, "openai_key")
```

## Real-world example  -  multi-service agent with OpenAI and Stripe

An agent that drafts payment summaries by calling both OpenAI and the Stripe API. Two secrets, one sandbox, no credentials in the VM.

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])
sandbox = client.sandboxes.create(template_id="python-ds")

# Store both secrets
sandbox.secrets.set(
    name="openai_key",
    value=os.environ["MY_OPENAI_KEY"],
    expose_as_env="OPENAI_API_KEY",
)
sandbox.secrets.set(
    name="stripe_key",
    value=os.environ["MY_STRIPE_KEY"],
    expose_as_env="STRIPE_SECRET_KEY",
)

agent_code = '''

# Both env vars are placeholders; the proxy swaps them on egress
OPENAI_API_KEY = os.environ["OPENAI_API_KEY"]
STRIPE_SECRET_KEY = os.environ["STRIPE_SECRET_KEY"]

# Fetch recent Stripe charges
charges = requests.get(
    "https://api.stripe.com/v1/charges?limit=5",
    auth=(STRIPE_SECRET_KEY, ""),
).json()["data"]

# Ask OpenAI to summarize them
summary_prompt = "Summarize these Stripe charges in one sentence: " + json.dumps(charges)
resp = requests.post(
    "https://api.openai.com/v1/chat/completions",
    headers={"Authorization": f"Bearer {OPENAI_API_KEY}"},
    json={"model": "gpt-4o-mini", "messages": [{"role": "user", "content": summary_prompt}]},
)
print(resp.json()["choices"][0]["message"]["content"])
'''

sandbox.files.write("/workspace/agent.py", agent_code)
result = sandbox.exec("python /workspace/agent.py")
print(result.stdout)
```

```typescript

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
const sandbox = await client.sandboxes.create({ template: 'node-web' });

await sandbox.secrets.set({
  name: 'openai_key',
  value: process.env.MY_OPENAI_KEY!,
  exposeAsEnv: 'OPENAI_API_KEY',
});
await sandbox.secrets.set({
  name: 'stripe_key',
  value: process.env.MY_STRIPE_KEY!,
  exposeAsEnv: 'STRIPE_SECRET_KEY',
});

const agentCode = `
const resp = await fetch('https://api.stripe.com/v1/charges?limit=5', {
  headers: { Authorization: 'Bearer ' + process.env.STRIPE_SECRET_KEY },
});
const { data: charges } = await resp.json();

const ai = await fetch('https://api.openai.com/v1/chat/completions', {
  method: 'POST',
  headers: {
    Authorization: 'Bearer ' + process.env.OPENAI_API_KEY,
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    model: 'gpt-4o-mini',
    messages: [{ role: 'user', content: 'Summarize: ' + JSON.stringify(charges) }],
  }),
});
const { choices } = await ai.json();
console.log(choices[0].message.content);
`;

await sandbox.files.write('/workspace/agent.ts', agentCode);
const result = await sandbox.exec('npx tsx /workspace/agent.ts');
console.log(result.stdout);
```

## Troubleshooting

**The sandbox env var is empty  -  `echo $OPENAI_API_KEY` prints nothing.**
The secret was saved at `scope="tenant"` or `scope="workspace"` but the sandbox doesn't belong to that scope. Re-save with `scope="sandbox"` (the default when using `sandbox.secrets.set`).

**`secrets.list()` shows the secret but the upstream API returns 401.**
The proxy is not seeing the placeholder in the request. Confirm the library you're using puts the token in `Authorization: Bearer ...`. Check the audit row's `request_transforms.secrets.swapped`  -  if empty, the proxy never matched.

**I rotated the key but nothing changed.**
Rotation is instant. The upstream API call succeeding after rotation means the new key is already working. Verify the old key is actually invalid by revoking it on the provider side.

**I deleted a secret but the env var still has a value inside the sandbox.**
The sandbox process caches env vars at startup. Restart the process or open a new exec session  -  the proxy checks the vault on each request, but the env var in the process's memory reflects the last value it read.

For more issues, see the [Security troubleshooting hub](/docs/security/troubleshooting).

## Frequently asked

**Can I read a secret's real value via the SDK after I save it?**
No. `secrets.list` returns metadata only (name, type, preview, last-used time). The value is sealed.

**What if I want to keep using `.env` files?**
Use them. MIOSA Secrets is purely additive; `.env` files continue to work. Use Secrets for credentials you want centrally managed.

**Will this slow my sandbox down?**
About 1-3 ms per outbound request. Trivial vs typical API latency.

**Does it work with `curl`, `requests`, `fetch`, `axios`, `gRPC`, …?**
Yes. The proxy operates at the network layer; the swap is invisible to the language runtime.

Source: src/routes/docs/security/troubleshooting/+page.md
Description: Top 15 issues across MIOSA Secrets, Connect Accounts, Network Allowlist, Audit Log, and White-label Credentials  -  with root causes and fixes.

# Security  -  Troubleshooting

Quick-reference for the 15 most common issues across all MIOSA Security features. Each entry: symptom → root cause → fix.

---

## Secrets

### 1. Secret value is not being swapped: outbound request uses the raw placeholder

**Symptom**: Your sandbox sees `miosa-tok-...` in `$OPENAI_API_KEY` and that placeholder reaches the upstream API, which returns a 401.

**Root cause**: The proxy swaps placeholders by scanning the outbound request for known token prefixes. If the request uses a non-standard header name or doesn't include the `Authorization` header at all, the swap is skipped.

**Fix**:
- Confirm the SDK or library you're using puts the token in the `Authorization: Bearer ...` header.
- For query-string auth (e.g., `?api_key=...`), make sure the token appears verbatim in the query string  -  the proxy scans query params too.
- Check the audit row's `request_transforms.secrets.swapped` field. If it's empty, the proxy didn't match the placeholder.
- Verify the env var name casing matches exactly. `OPENAI_API_KEY` ≠ `openai_api_key`. The proxy is case-sensitive when looking up `expose_as_env` bindings.

---

### 2. `secrets.list()` shows the secret but `$ENV_VAR` is empty inside the sandbox

**Symptom**: The secret is listed in the dashboard and SDK, but `echo $OPENAI_API_KEY` inside the sandbox returns nothing.

**Root cause**: The secret was created with `scope="tenant"` or `scope="workspace"` but the sandbox was not created under the same workspace. Or the `expose_as_env` value has a typo.

**Fix**:
```python
# Check the binding on the sandbox directly
secrets = sandbox.secrets.list()
for s in secrets:
    print(s.name, s.expose_as_env, s.scope)

# If missing, bind it explicitly to this sandbox
sandbox.secrets.set(
    name="openai_key",
    value="sk-proj-...",
    expose_as_env="OPENAI_API_KEY",
)
```

---

### 3. Rotating a key doesn't take effect  -  sandbox still uses the old key

**Symptom**: You called `sandbox.secrets.rotate(name, new_value=...)` but outbound calls to the API still succeed with what appears to be the old key.

**Root cause**: This is almost always correct behavior. Rotation is instant  -  the proxy looks up the new value on the next request carrying the placeholder. If the upstream call succeeds after rotation, the new key is already working. The old key may still be valid on the provider's side (keys aren't invalidated on MIOSA's end  -  only on the provider's end).

**Fix**: Verify rotation worked by checking the audit log:
```python
events = sandbox.audit.list(since="5m", host="api.openai.com", limit=5)
for e in events:
    print(e.timestamp, e.status_code, e.request_transforms)
```
If `status_code` is 200 after rotation, the new key is in use.

To force the old key to stop working: revoke it on the provider's side (e.g., delete it in the OpenAI dashboard), then rotate on MIOSA.

---

## Connect Accounts (OAuth)

### 4. GitHub OAuth refresh failing  -  sandbox gets 401 on `api.github.com`

**Symptom**: The sandbox was working, then suddenly starts getting 401s from GitHub. The audit log shows `action=allow` but `status_code=401`.

**Root cause**: The GitHub access token expired and the refresh attempt failed. This happens when:
- The user revoked the GitHub OAuth app's access from their GitHub settings
- The refresh token itself expired (GitHub personal OAuth tokens don't expire, but GitHub Apps tokens do after 8 hours without a refresh)
- The scopes were changed on the provider side

**Fix**:
1. In the MIOSA dashboard → Secrets tab, the GitHub entry will show "Reconnect needed."
2. Call `flow.reauthorize()` to re-run the OAuth dance:
```python
flow = sandbox.secrets.reauthorize(provider="github")
print("Authorize at:", flow.authorize_url)
flow.wait_for_completion(timeout=300)
```

---

### 5. Custom OAuth provider returns "invalid_state"

**Symptom**: The OAuth callback from a custom OAuth2 provider includes `error=invalid_state`.

**Root cause**: The `state` parameter in the OAuth dance has a 10-minute TTL. If the user took more than 10 minutes to authorize, or if the callback was called twice (e.g., the user hit the back button and tried again), the state is expired or consumed.

**Fix**: Re-initiate the flow. State is one-time use.
```python
# Don't reuse the old flow object  -  create a new one
flow = sandbox.secrets.connect(
    provider="my_custom_provider",
    expose_as_env="MY_API_TOKEN",
)
print("New authorize URL:", flow.authorize_url)
```
If you're building the UI, show the user a "Try again" button that calls your backend to initiate a fresh `connect()`.

---

### 6. Provider OAuth app shows "Authorize MIOSA" instead of my brand

**Symptom**: Your end-users see the MIOSA branding on the GitHub (or other provider) consent screen.

**Root cause**: You haven't registered a custom OAuth app override for your tenant.

**Fix**: See [White-label OAuth setup](/docs/security/white-label#white-label-oauth-your-branding-not-miosas). Register your own OAuth app with the provider, then add the override in Settings → OAuth Providers.

---

## Network Allowlist

### 7. Sandbox can't reach `pypi.org` after lockdown

**Symptom**: `pip install <package>` fails with a connection error after you locked down the network.

**Root cause**: `pip` contacts three domains, and all three must be on the allowlist:

| Domain | What it does |
|---|---|
| `pypi.org` | Package index queries |
| `files.pythonhosted.org` | Package download CDN |
| `pythonhosted.org` | Legacy package downloads (some packages still use this) |

**Fix**:
```python
sandbox.network.allow("pypi.org")
sandbox.network.allow("files.pythonhosted.org")
sandbox.network.allow("pythonhosted.org")
# If you also need conda:
sandbox.network.allow("conda.anaconda.org")
sandbox.network.allow("repo.anaconda.com")
```

---

### 8. `npm install` fails after lockdown

**Symptom**: `npm install` or `pnpm install` fails after switching to enforce mode.

**Root cause**: The npm registry and its CDN are not on the allowlist.

**Fix**:
```python
sandbox.network.allow("registry.npmjs.org")
sandbox.network.allow("*.npmjs.com")
```
If you use pnpm's own mirror:
```python
sandbox.network.allow("registry.npmjs.org")
```

---

### 9. Agent stopped calling a host that's on the allowlist

**Symptom**: You can see the host in your allowlist, but the agent keeps getting blocked.

**Root cause**: The agent is resolving a subdomain or alias not covered by your rule. For example, `api.openai.com` is on the list but the agent is also hitting `oai.endpoint.amazonaws.com` (OpenAI's backend CDN).

**Fix**:
1. Check the Pending Requests queue:
```python
pending = sandbox.network.pending()
for p in pending:
    print(p.host, p.request_count)
```
2. Add any missing hosts to the allowlist.
3. For CDNs and dynamic subdomains, use a wildcard: `*.openai.com`.

---

### 10. I locked down a sandbox but all new sandboxes from the same template are locked too

**Symptom**: Sandboxes created from a template inherit enforce mode unexpectedly.

**Root cause**: The template you snapshotted was already in enforce mode. The policy state is part of the template snapshot.

**Fix**: After creating a sandbox from the template, immediately call:
```python
new_sandbox.network.observe()
```
To prevent this for all future sandboxes, snapshot the template while it's in audit-only mode.

---

## Audit Log

### 11. Audit log is empty  -  no rows for a sandbox that's been running

**Symptom**: `sandbox.audit.list(since="24h")` returns an empty list, even though the sandbox is running and making calls.

**Root cause**: Either:
- The sandbox isn't making any *outbound* calls (the audit log only records egress, not inbound traffic)
- The sandbox was created before the MIOSA egress feature was enabled on your tenant

**Fix**: Confirm outbound traffic from inside the sandbox:
```python
r = sandbox.exec("curl -s -o /dev/null -w '%{http_code}' https://api.openai.com/")
print(r.stdout)  # 401 is fine  -  it proves egress happened
```
Then re-query the audit log. If still empty after confirmed egress, file a support ticket.

---

### 12. Audit rows show `request_transforms.secrets.swapped = []` even though a secret is bound

**Symptom**: The request to `api.openai.com` succeeds, but the audit row shows no secrets were swapped.

**Root cause**: The secret binding was added *after* this particular request was made, or the sandbox resolved the real key from a `.env` file rather than the placeholder (so no swap was needed).

**Fix**: Check whether the env var contains a placeholder or the real key:
```python
r = sandbox.exec("echo $OPENAI_API_KEY")
print(r.stdout)
# "miosa-tok-..." means placeholder is present → proxy will swap
# "sk-proj-..."  means real key is in the env → proxy has nothing to swap
```
If the real key is in the env var (e.g., from a `.env` file), the proxy never sees the placeholder and no swap occurs.

---

## White-label

### 13. Audit query by `external_user_id` returns rows from other users

**Symptom**: `client.audit.list(external_user_id="alice@example.com")` returns events that clearly belong to other users.

**Root cause**: This should not happen  -  `external_user_id` is a strict equality filter within your tenant. Most commonly this is a wildcard match being applied in your own code.

**Fix**: Verify you're passing the exact ID, not a pattern:
```python
# Correct
events = client.audit.list(external_user_id="alice@example.com")

# Wrong  -  this is not a prefix match, but double-check your exact string
events = client.audit.list(external_user_id="alice@")  # won't match anything
```
If the issue persists, check that multiple sandboxes aren't all being created with the same `external_user_id` by mistake.

---

### 14. `scope="external_user"` secret returns 403

**Symptom**: Calling `client.secrets.set(..., scope="external_user", external_user_id="...")` returns HTTP 403.

**Root cause**: Your tenant has "Allow end-user-scoped credentials" disabled.

**Fix**: In the MIOSA dashboard → Settings → Security → toggle "Allow end-user-scoped credentials" to On. If you intentionally disabled it and this call is from your own backend (not an end-user), use `scope="tenant"` or `scope="external_workspace"` instead.

---

### 15. Resolver scope walk skips an expected secret

**Symptom**: A sandbox with `external_user_id="alice"` doesn't pick up a secret set at `scope="external_workspace"` for `external_workspace_id="team-a"`, even though Alice is in team-a.

**Root cause**: The resolver scope walk uses the `external_workspace_id` stamped on the sandbox at creation time. If the sandbox was created without `external_workspace_id="team-a"`, the workspace-level secret doesn't resolve for it.

**Fix**: Verify the sandbox has the right workspace stamp:
```python
sbx = client.sandboxes.get(sandbox_id)
print(sbx.external_workspace_id)   # should be "team-a"
```
If it's missing or wrong, create a new sandbox with the correct attribution. Attribution fields are immutable after creation.

---

## Still stuck?

- Use the Audit Log → detail drawer: each row shows exactly which transforms ran and which rules fired.
- Check [Network Allowlist](/docs/security/network), [Secrets](/docs/security/secrets), [Connect Accounts](/docs/security/connect-accounts) for full reference docs.
- For bugs, open a support ticket from the MIOSA dashboard  -  include the sandbox ID and the relevant audit row ID.

# End-user credentials and OAuth

URL: https://miosa.ai/docs/security/white-label
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/security/white-label
Source: src/routes/docs/security/white-label/+page.md
Description: How to scope secrets and OAuth connections to your own end-users on top of MIOSA  -  with your branding, not ours.

# End-user credentials and OAuth

If you're building a product **on top of MIOSA** (an AI coding agent, a vertical SaaS, an agency tool) and your end-users create sandboxes through *your* UI, MIOSA Security supports them as first-class identities  -  even though they don't have MIOSA accounts.

This page covers:

1. Attributing sandboxes to your end-users with `external_user_id`
2. Storing credentials scoped to those end-users
3. Branding the OAuth consent flow as your own product
4. Auditing per end-user, per workspace

## Background  -  external attribution

Every Computer and Sandbox already supports three caller-supplied attribution fields:

| Field | Purpose |
|---|---|
| `external_user_id` | Your end-user's identity in your system |
| `external_workspace_id` | Your workspace/team grouping |
| `external_project_id` | Your project identity |

These are labels, not authentication boundaries. But MIOSA Security uses them as **credential-scoping keys**, which means you can store secrets that resolve only for *that* end-user's resources.

See [External Attribution](/docs/platform/attribution) for the broader picture.

## Stamping attribution at create time

When your backend creates a sandbox for one of your end-users, pass the attribution:

```python
sandbox = client.sandboxes.create(
    template_id="python-ds",
    external_user_id="dana@example.net",
    external_workspace_id="acme",
    external_project_id="intake-flow",
)
```

```typescript
const sandbox = await client.sandboxes.create({
  template: 'node-web',
  externalUserId: 'dana@example.net',
  externalWorkspaceId: 'acme',
  externalProjectId: 'intake-flow',
});
```

```go
sandbox, err := client.Sandboxes.Create(ctx, miosa.SandboxCreate{
    Template:            "python-ds",
    ExternalUserID:      "dana@example.net",
    ExternalWorkspaceID: "acme",
    ExternalProjectID:   "intake-flow",
})
```

```java
Sandbox sandbox = client.sandboxes().create(SandboxCreate.builder()
    .template("python-ds")
    .externalUserId("dana@example.net")
    .externalWorkspaceId("acme")
    .externalProjectId("intake-flow")
    .build());
```

```elixir
{:ok, sandbox} = Miosa.Sandboxes.create(%{
  template_id: "python-ds",
  external_user_id: "dana@example.net",
  external_workspace_id: "acme",
  external_project_id: "intake-flow"
})
```

The values you choose are opaque to MIOSA  -  they're whatever IDs make sense in your system.

## Storing a credential scoped to an end-user

Suppose Dana pastes her own OpenAI key into your UI. Save it scoped to her:

```python
client.secrets.set(
    name="openai_key",
    value="sk-proj-her-personal-key...",
    scope="external_user",
    external_user_id="dana@example.net",
    expose_as_env="OPENAI_API_KEY",
)
```

Now any sandbox you create with `external_user_id="dana@example.net"` resolves `OPENAI_API_KEY` to her key. Other members in the same account do **not** see it.

For an account-wide credential (for example a shared company key):

```python
client.secrets.set(
    name="ehr_api_key",
    value="...",
    scope="external_workspace",
    external_workspace_id="acme",
    expose_as_env="EHR_API_KEY",
)
```

## How the proxy decides which credential to use

When a sandbox makes an outbound call and the proxy needs to swap a placeholder, it walks (in priority order):

```
1. Direct binding on this specific sandbox
2. Secret scoped to user (owner_user_id  -  for MIOSA-native users)
3. Secret scoped to external_user (external_user_id match)
4. Secret scoped to external_workspace (external_workspace_id match)
5. Secret scoped to MIOSA workspace
6. Tenant-wide secret
```

First match wins. If nothing matches, the placeholder stays in the request and the upstream call fails (the right behavior  -  better than silently leaking).

## White-label OAuth (your branding, not MIOSA's)

By default, when one of your end-users clicks "Connect GitHub" in your UI, they're sent to GitHub with the consent screen showing **"Authorize MIOSA"**. For a true white-label experience, override that:

### 1. Register your own OAuth app on the provider

For GitHub:

```
https://github.com/settings/applications/new

Application name:  Lumen Cloud
Homepage URL:      https://lumen.example
Authorization callback URL:  https://app.lumen.example/oauth/callback
```

### 2. Drop the credentials into MIOSA

In your tenant admin dashboard → Settings → OAuth Providers → "Add provider override":

```
Provider:       github
Display name:   GitHub
Client ID:      <from GitHub>
Client Secret:  <from GitHub>
Callback URL:   https://app.lumen.example/oauth/callback
Branding:       { "button_label": "Connect GitHub to Lumen" }
```

From now on, when one of your end-users connects GitHub, they see "Authorize Lumen Cloud"  -  your name, your branding, your callback domain.

### 3. Make sure your callback proxies to MIOSA

Your `https://app.lumen.example/oauth/callback` route receives the OAuth `code` parameter and forwards it to MIOSA's callback endpoint:

```python
@app.get("/oauth/callback")
def oauth_callback(request):
    code = request.query_params["code"]
    state = request.query_params["state"]
    # Forward to MIOSA
    return miosa.oauth.complete(provider="github", code=code, state=state)
```

MIOSA exchanges the code for tokens on your behalf and stores them in the vault.

## Per-user auditing

Audit log carries the full identity chain on every row, so you can query by your own user IDs:

```python
# All activity by one end-user
events = client.audit.list(
    since="7d",
    external_user_id="dana@example.net",
)

# All activity in one workspace
events = client.audit.list(
    since="30d",
    external_workspace_id="acme",
)
```

Same filters available in the UI.

## Privacy boundary

What a tenant admin (you, as the white-label operator) can do:

- ✅ See that a particular `external_user_id` has secrets bound to them
- ✅ Read audit rows showing which credential resolved for each call
- ✅ Disable a secret to immediately revoke access
- ❌ Re-read the encrypted value of any stored secret

The "you can't read stored values" rule applies to every actor in MIOSA  -  including the platform engineers. If one of your end-users ever asks "can Lumen see my OpenAI key after I save it"  -  the answer is "no, the value is encrypted; only the request body that leaves your sandbox ever contains it, briefly, in transit."

## Disabling end-user-scoped credentials entirely

Some white-label customers want all credentials managed centrally  -  end-users can't bring their own keys. Toggle this in your tenant settings:

```
Settings → Security → "Allow end-user-scoped credentials" → Off
```

When off, only `tenant` and `external_workspace` scoped secrets resolve. End-user-scoped secret creation returns a 403.

## Real-world example  -  Lumen: one sandbox per end user

Lumen is a SaaS built on MIOSA. Each of Lumen's end users gets their own sandbox. They supply their own OpenAI key through the Lumen settings page. The audit log is surfaced in Lumen's own dashboard. GitHub OAuth shows "Authorize Lumen", not "Authorize MIOSA".

```python

from miosa import Miosa
from flask import Flask, request, jsonify, redirect

app_server = Flask(__name__)
client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

def get_or_create_sandbox(member_id: str, account_id: str):
    """Return existing sandbox or create a new one for this member."""
    sandboxes = client.sandboxes.list(external_user_id=member_id)
    if sandboxes:
        return sandboxes[0]
    return client.sandboxes.create(
        template_id="python-ds",
        external_user_id=member_id,

    client.oauth.complete(

        state=request.args["state"],
    )
    return redirect("/dashboard?connected=github")

@app_server.get("/api/members/<member_id>/activity")
def member_activity(member_id: str):

    events = client.audit.list(

    )
    return jsonify([{

        "host": e.host,
        "action": e.action,
        "status": e.status_code,
    } for e in events])
```

```typescript

    state: req.query.state as string,
  });
  res.redirect('/dashboard?connected=github');
});

app.get('/api/members/:memberId/activity', async (req, res) => {
  const events = await client.audit.list({
    since: '7d',
    externalUserId: req.params.memberId,
    limit: 200,
  });
  res.json(events.map(e => ({ time: e.timestamp, host: e.host, action: e.action, status: e.statusCode })));
});
```

## Troubleshooting

**Sandbox can't find the secret I stored for an end-user  -  env var is empty.**
The sandbox must have been created with the same `external_user_id` you used for the secret. Attribution is stamped at creation time and cannot be changed. Verify with `client.sandboxes.get(sandbox_id).external_user_id`.

**`scope="external_user"` returns HTTP 403.**
Your tenant has "Allow end-user-scoped credentials" disabled. Enable it in Settings → Security, or use `scope="external_workspace"` for workspace-level credentials instead.

**The resolver skips my workspace-scoped secret.**
The sandbox must have been created with a matching `external_workspace_id`. If the sandbox was created without it, the workspace-level scope walk entry is blank and won't match.

**OAuth consent screen still says "Authorize MIOSA" after I added a provider override.**
Double-check that the `client_id` in your override matches the OAuth app you registered with the provider, not MIOSA's default client ID. Remove and re-add the override if needed.

**My end-user can see other users' sandboxes in the MIOSA dashboard.**
End-users should not have MIOSA accounts or API keys. If they do, create a browser token scoped to that user instead: `client.browser_tokens.create(external_user_id="...")`. Browser tokens are read-only and scoped to that user's resources.

For more issues, see the [Security troubleshooting hub](/docs/security/troubleshooting).

## Frequently asked

**My end-users don't have MIOSA accounts. Can they still use OAuth Connect?**
Yes. The OAuth flow attributes the resulting token to whatever `external_user_id` your backend passes when initiating the flow.

**Can the same `external_user_id` exist in multiple tenants?**
Yes  -  `external_user_id` is scoped within a tenant. The same string in two different tenants represents two independent identities.

**What if an end-user is in two of my workspaces?**
You can create credentials at the workspace scope for each  -  the proxy resolves the correct one based on which sandbox is making the request.

**Can my end-users see the audit log themselves?**
That's your call  -  MIOSA gives you the audit data; how you expose it in your white-labeled UI is up to you. Most white-label customers surface "your activity" to end-users in their own dashboards.

**How do I migrate existing in-app secret storage to MIOSA Secrets?**
Bulk import via SDK is the easiest path:

```python
for user_id, openai_key in your_existing_secret_store.items():
    client.secrets.set(
        name="openai_key",
        value=openai_key,
        scope="external_user",
        external_user_id=user_id,
        expose_as_env="OPENAI_API_KEY",
    )
```

Once verified, delete from your old store.

# Services CLI

URL: https://miosa.ai/docs/services/cli
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/cli
Source: src/routes/docs/services/cli/+page.md
Description: Every miosa service command and flag, from create and deploy to variables, domains, releases and rollback.

# Services CLI

`miosa service` operates Services.
`miosa services` and `miosa svc` are aliases.
A named background process inside a sandbox is `miosa daemon`, a different product.

`<project>` is a project name, slug or id.
`<service>` is a service name, slug or id; the CLI resolves the name to the id the API needs.
`<release>` is a release number or id.
Every command accepts `--json`.

## Commands

| Command | What it does |
|---|---|
| `service create <project> <name>` | Create a web service, worker, private service, static site, cron job or database service |
| `service list <project>` | List the project's services |
| `service get <project> <service>` | Show one service |
| `service update <project> <service>` | Change the name, start command, replicas or region |
| `service deploy <project> <service>` | Build and release |
| `service logs <project> <service>` | Show a release's transitions and failure reason |
| `service scale <project> <service>` | Change replicas, region or limits |
| `service start <project> <service>` | Start a stopped service |
| `service stop <project> <service>` | Stop every active release now |
| `service restart <project> <service>` | Queue a release that restarts the service |

| `service domains <project> <service>` | Show the private and public addresses |
| `service domains enable <project> <service>` | Give the service a public address |
| `service domains disable <project> <service>` | Remove the public address |
| `service vars list <project> <service>` | List variables, masked |
| `service vars set <project> <service> KEY=VALUE...` | Set variables |
| `service vars unset <project> <service> NAME[,NAME]` | Delete variables |
| `service vars effective <project> <service>` | Show what a deploy would receive |
| `service vars reveal <project> <service> NAME` | Print one value |
| `service runs <project> <service>` | A cron service's recent runs |
| `service connection <project> <service>` | A database service's URLs |
| `service settings <project>` | What each setting does today |

| `project target duplicate <project> <target> --name <new>` | Copy a Deploy target's services and variables |
| `project target rm <project> <target>` | Delete a Deploy target |

## `service create` flags

| Flag | Meaning |
|---|---|
| `--type` | `web`, `worker`, `private`, `static`, `schedule` or `database` (default `web`) |
| `--repo`, `--branch`, `--root-dir` | A git source |
| `--image`, `--port` | A container image source |
| `--dockerfile` | Dockerfile path for a git source (needs Services build cells) |
| `--start-command` | Command the service starts with |
| `--replicas` | 1 to 50 |
| `--region` | `us-west`, `us-east` or `us-mia` |
| `--schedule` | Five-field schedule expression, required for `--type schedule` |
| `--env KEY=VALUE` | A variable; repeatable, and a value may be a `${{...}}` reference |
| `--no-public` | Do not give a web or static service a public address |
| `--slug` | Host label (default: from the name) |
| `--deploy-target` | Deploy target name or id (default: the project's default) |

A web or static service gets its public address enabled right after creation unless `--no-public` is passed.
If the address cannot be enabled the service is still created and the CLI prints a warning.

## `service deploy` flags

| Flag | Meaning |
|---|---|
| `--dir` | Upload this local directory as the source |
| `--repo`, `--branch`, `--root-dir` | Deploy a git source |
| `--image`, `--port` | Deploy a container image |
| `--message` | Release message |
| `--wait`, `--timeout` | Follow the release until it is live or fails |
| `--deploy-target` | Deploy target name or id |

With no source flag the service's own source is rebuilt.

## `service get`

`service get` prints the service, including `Pending changes` when a variable write made the running release stale.
The value is `rebuild` (a build-visible variable changed) or `redeploy` (any other variable), and `miosa service deploy` is the action that clears it.

## `service logs`

`logs` prints the newest release's state transitions and its failure reason.
Pass `--release <number|id>` for an older one.
`--follow` is refused until the Services log stream ships; the release events carry the reason a release failed.

## Deploy targets

Every project has a default Deploy target, and the first read creates `production`.
Services, variables and releases live inside one Deploy target; `--deploy-target` picks it and defaults to the project's default.

```bash
miosa project target list shop
miosa project target duplicate shop production --name staging
miosa service list shop --deploy-target staging
```

A duplicate copies services and variables; secrets are generated again and no data or managed database is copied.

## Confirmation

`stop`, `delete`, `rollback` and `promote` ask for confirmation on a terminal and refuse in a script unless `--yes` is passed.

### Deleting a database service

Deleting a database service also deletes its database and every row in it.
It cannot be undone, so it needs the service's exact name, not `--yes`:

- On a terminal, the CLI asks you to type the name.
- In a script, pass `--confirm <exact name>`.
- `--yes` alone is not enough.
- A run with no terminal and no `--confirm` exits with code 2 and sends nothing.
- A `--confirm` that does not match the name exactly also exits with code 2.

```bash
miosa service delete shop Postgres --confirm Postgres
```

`--confirm` needs CLI 2.13.3 or later.

## Automation

Every command is non-interactive with `--yes` (deleting a database service needs `--confirm <name>` instead), prints JSON with `--json`, and exits non-zero on an API error.
The API's error code is preserved; for example a stale settings write exits non-zero with `STALE_SERVICE`.

# Service settings as code

URL: https://miosa.ai/docs/services/config-file
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/config-file
Source: src/routes/docs/services/config-file/+page.md
Description: Put a service's settings in a file at the repository root, so the repository says how the service runs and the console shows where each value came from.

# Service settings as code

A service can carry its settings in a file at the repository root. The same file
works for Docker Host and for Services:

- `miosa.app.yml`, `miosa.app.yaml` or `miosa.app.json`, and
- `miosa.json`.

`railway.json` is read as a compatible fallback, so a project imported from
Railway needs no edit first.

## Rules

**Only the fields the file names change.** A file with one key leaves every other
setting as the project has it. A file is an addition, not a replacement.

**The API still validates.** The merged settings go through the same validation
as a console save, so a file cannot write a value the API would refuse.

**The file wins over the console for the fields it names.** The console shows
which fields came from the file.

## Fields

| File key | Setting | Applies to |
|---|---|---|
| `deploy.start` / `startCommand` / `start_command` | Start command | all |
| `deploy.preDeploy` / `preDeployCommand` | Pre-deploy command | all |
| `deploy.healthcheckPath` / `healthcheck_path` | Health check path | web services |
| `deploy.healthcheckTimeout` | Health check timeout, seconds | web services |
| `deploy.restartPolicy` / `restartPolicyType` | `always`, `on_failure` or `never` | all |
| `deploy.maxRetries` / `restartPolicyMaxRetries` | Retries before giving up | all |
| `deploy.replicas` / `numReplicas` | Replicas | all |
| `deploy.cron` / `cronSchedule` | Five-field schedule | cron services |
| `deploy.region` | `us-east`, `us-west` or `us-mia` | all |
| `deploy.sleep` / `sleepApplication` | Sleep when idle, five minutes by default | web services with a public address |
| `build_command` | Build command, Railpack builds only | static services |
| `output_dir` | Directory to serve, relative to the app | static services |

`variables` are read as names; values are not taken from the file.

## What the file cannot carry

Keys with no equivalent are reported in the plan and in the console rather than
dropped quietly: `build.builder`, `build.dockerfilePath`, and anything unknown.

Every field the file sets is recorded against the file and key that set it, so
"why is the start command this?" has an answer months later.

# Dedicated vCPU

URL: https://miosa.ai/docs/services/dedicated-vcpu
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/dedicated-vcpu
Source: src/routes/docs/services/dedicated-vcpu/+page.md
Description: Run a service on vCPUs that are one hardware thread each and never shared: sizes, prices, and how to select one.

# Dedicated vCPU

A dedicated size gives a service vCPUs it owns outright.
Each dedicated vCPU is one hardware thread of the host, pinned to your service and never shared with another workload.
Use it when you need steady CPU with no noisy neighbors.

Dedicated sizes are available on Business and above.

## Sizes and prices

Memory is 4 GiB per vCPU.

| Size | vCPU | Memory | Price per month |
|---|---|---|---|
| `dedicated-2` | 2 | 8 GiB | $153.37 |
| `dedicated-4` | 4 | 16 GiB | $306.74 |
| `dedicated-8` | 8 | 32 GiB | $613.48 |
| `dedicated-16` | 16 | 64 GiB | $1,226.95 |

- A dedicated vCPU costs $32.8725 a month ($0.04503 an hour), and memory costs the normal $10.953 per GiB-month.
- A dedicated service is billed for its full size for every second a replica runs, whether the CPU is busy or idle.
- A stopped or sleeping service is not billed for compute.
- The same vCPUs and memory on a shared size cost about 17 percent less, without the guarantee.

## Select a size

Set `shape` in the service settings.

```bash
curl -X PATCH https://api.miosa.ai/api/v1/projects/{id}/services/{sid} \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"settings": {"shape": "dedicated-4"}}'
```

- The size applies to the next deployment.
- `replicas` multiplies it: three replicas of `dedicated-4` use 12 dedicated vCPUs.
- If you also set `limits`, they must fit inside the size.
- Check `GET /api/v1/projects/{id}/services/setting-capabilities`: the `shape` entry reads `enforced` when dedicated sizes are available to place.

## Capacity

Dedicated vCPUs come from a fixed pool of 16 threads on each host that carries one.
A deployment is placed only on such a host, and it is refused with `no_capacity` when that host's pool has too few free threads.
A deployment of 16 vCPUs takes a whole host pool.
Free threads return to the pool when a replica stops.

# Services addresses and domains

URL: https://miosa.ai/docs/services/domains
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/domains
Source: src/routes/docs/services/domains/+page.md
Description: How services reach databases while private networking is not available, the public miosa.app address a web service or static site can have, and how TLS is handled.

# Services addresses and domains

Services reach managed databases through their connection variables.
A web service or a static site can also have a public address.

## Private networking

Private networking between services is not available yet.
One service cannot reach another by a private name, and `private_network` reads `{"enabled": false}`.
The older `private_domain` field (`<service-slug>.miosa.internal`) and the `MIOSA_PRIVATE_DOMAIN` variable do not resolve; do not build on them.

Managed databases connect automatically from any host.
Reference a database's connection in the service's Variables:

```text
DATABASE_URL=${{Postgres.DATABASE_URL}}
REDIS_URL=${{Redis.REDIS_URL}}
```

To call another service of the project, give it a public address and call that.
The service's Networking tab in the console shows the same.

## Public address

```bash
miosa service domains shop API
miosa service domains enable shop API --label api
miosa service domains disable shop API
```

`enable` gives the service:

```text
https://<label>.<your-org>.miosa.app
```

The label defaults to the service's slug and must be lowercase a-z, 0-9 and `-`.
The label is unique across your organization.
TLS is issued and renewed by the platform; there is no certificate to install.

`disable` removes the public address and leaves the private one in place.
The service keeps running; it just stops being reachable from the internet.

## What serves a public address

The public address routes to the healthy replicas of the service's active release.
A release that is not `active` does not receive traffic.

If the service has idle sleep enabled, a request to a sleeping service wakes it and waits for it.
A service without a public address has no request signal, so it never sleeps.

## Reading the address in code

TypeScript:

```typescript
const service = await miosa.services.get(serviceId);
console.log(service.private_network);       // { enabled: false } while private networking is not available
console.log(service.public_address.url);    // null until enabled
```

Python:

```python
service = miosa.services.get(service_id)
print(service["private_network"])
print(service["public_address"]["url"])
```

## Custom domains

The public address is on `miosa.app`.
A custom domain on your own DNS zone is a separate product: register it, add the CNAME it shows and let MIOSA verify it.
That flow lives under Domains, not under a service, so one domain can outlive a service.

## When ingress is off

If public addresses are not switched on for the platform, `enable` answers `INGRESS_DISABLED` (404).
The service still runs, but has no address to reach it on, and `miosa service settings shop` reports `public_address` as `unsupported`.

# Services environments

URL: https://miosa.ai/docs/services/environments
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/environments
Source: src/routes/docs/services/environments/+page.md
Description: Every project starts with a production environment. Fork it into staging or a preview, and switch between environments on the canvas.

# Services environments

An environment is a copy of a project that runs on its own.
Every project starts with a `production` environment.
Add `staging`, a preview, or anything else you need.

Each environment has its own services, variables and releases.
A change in staging does not touch production.

## Switch and fork on the canvas

The environment name sits in the canvas top bar, next to the project name.
Open it to see every environment of the project and to switch between them.
The canvas reloads for the environment you pick, and the address carries it as `?env=<name>`.

Choose **Fork** to create a new environment from the one you are looking at.
Give it a name.
MIOSA copies the services and variables, then shows a summary of what was copied and what was skipped.

## From the API

```text
GET  /api/v1/projects/:id/environments
POST /api/v1/projects/:id/environments/:env/duplicate   {"name": "staging"}
```

`duplicate` returns the new environment, the services and variables it copied, and the entries it skipped.
The project's service routes accept `?env=<name>`; without it they use `production`.

## Where to go next

- [Variables](/docs/services/variables): variables and references are per environment.
- [Releases and rollback](/docs/services/releases): each environment has its own releases.
- Docker Host has its own [environments](/docs/docker-host/environments) for the former Docker Host deployments.

# Services logs

URL: https://miosa.ai/docs/services/logs
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/logs
Source: src/routes/docs/services/logs/+page.md
Description: Read a service's runtime logs per replica, the build log of a release, and the events that led to its state.

# Services logs

The service panel has a **Logs** tab with three views.

| View | Shows |
|---|---|
| Runtime | The newest lines each replica printed, with the replica's state. |
| Build | The log of the build that produced a release, with whether it finished. |
| Events | The state transitions of a release and the reason when it failed. |

A service that runs a container image has no build, so its Build view is empty.

## Runtime logs

Runtime logs are per replica.
Each replica reports its state and its lines, or an error when its log could not be read.
Each replica is listed separately, and the `replica` parameter reads one.

```text
GET /api/v1/projects/:id/services/:sid/logs?tail=200&replica=<id>
```

## Build logs

```text
GET /api/v1/projects/:id/services/:sid/builds/latest/logs?tail=200
GET /api/v1/projects/:id/services/:sid/builds/:build_id/logs?after=<offset>
```

The response carries the text, the offset to continue from, and `complete` once the build has finished.
Ask again with `after` set to the last offset to follow a running build.

## Events and failure reasons

```bash
miosa service logs shop API
```

The CLI prints the newest release's state transitions and its failure reason.
It does not stream runtime output.

## Where to go next

- [Releases and rollback](/docs/services/releases): the release states the events describe.
- [Replicas and scaling](/docs/services/replicas): what a replica is.

# Service metrics

URL: https://miosa.ai/docs/services/metrics
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/metrics
Source: src/routes/docs/services/metrics/+page.md
Description: Requests, errors and latency per service, and what the series does not measure.

# Service metrics

Every service reports its own request series: requests, errors, error rate, and
response latency at p50 and p95.

```bash
miosa service metrics lumen API
miosa service metrics lumen API --range 24h --json
```

The same series is at `GET /api/v1/projects/:id/services/:sid/metrics/series?range=`
with `15m`, `1h`, `6h`, `24h` or `7d`, scope `projects:read`.

## Reading it honestly

The server buckets the series and reports `step_seconds`: 60 for `15m` and `1h`,
300 for `6h`, 900 for `24h`, and 3600 for `7d`. The full timeline comes back even
in a quiet window, with null fields where nothing happened; a point is empty when
`requests` is null, and the CLI prints a dash rather than a zero.

`available` names what is actually measured. For a service that is `requests` and
`latency`; **cpu, memory and network are not collected for services**, and the CLI
says so under the table instead of printing empty columns.

Real-user web vitals (LCP, INP, FCP, TTFB, CLS) are collected for static and web
services that include the beacon, and come back under `web_vitals` with
`available.web_vitals`. They are reported separately because they measure the
browser, not the server.

# Edge middleware

URL: https://miosa.ai/docs/services/middleware
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/middleware
Source: src/routes/docs/services/middleware/+page.md
Description: Ordered path rules and an optional function that run at the edge, in front of a server service.

# Edge middleware

Edge middleware runs in front of a server service, before the request reaches
your process: redirects, rewrites, header changes, and optionally a published
function that can answer, continue or rewrite the request.

It is a structured rule set, so it is written as a file rather than a pile of
flags:

```bash
miosa middleware shop API --from middleware.json
miosa middleware shop API           # what is configured now
miosa middleware shop API --off     # remove the rules and the function
```

```json
{
  "rules": [
    { "path": "/old/*", "redirect": { "to": "/new", "status": 308 } },
    { "path": "/api/*", "request_headers": { "set": { "x-plan": "pro" } } }
  ],
  "function": { "slug": "gate", "paths": ["/app/*"], "timeout_ms": 250, "on_error": "closed" }
}
```

Rules run in order and there can be up to fifty of them. A `path` is either an
exact path or a prefix ending in `/*`, where `$1` is the rest of the path. Each
rule carries exactly one of a `redirect` (with an optional `301`, `302`, `303`,
`307` or `308`, default `307`), a `rewrite`, and/or header changes.

The function answers `x-miosa-middleware: next` to let the request continue, and
may add `x-miosa-middleware-request-<name>` or `x-miosa-middleware-rewrite`. Any
other answer is returned to the client. With `on_error: "closed"`, a failing
function answers `503 edge_middleware_unavailable`; with `open`, the request
continues.

Protected header names are refused, including `host`, `content-length`,
`transfer-encoding`, `connection`, `upgrade`, `x-internal-*`, `x-miosa-*` and
`x-forwarded-*`.

A change applies within about five seconds at every edge node. Validation errors
name the field (`settings.edge_middleware.<path>`), so a typo in a rule is easy to
find.

# Services

URL: https://miosa.ai/docs/services/overview
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/overview
Source: src/routes/docs/services/overview/+page.md
Description: Run web services, workers, private services and static sites in a project, with releases, variables, domains and rollback.

# Services

Services are the apps a project runs.
A service is one of four common types, plus cron jobs and database services:

| Type | What it is |
|---|---|
| Web service | A process that serves HTTP on a public address. |
| Worker | A process with no port and no address. It runs until it stops. |
| Private service | A process with no public address. Private networking between services is not available yet, so nothing else reaches it by name; it can reach managed databases through their connection variables. |
| Static site | Pre-built files served from the edge. |
| Cron job | A command on a five-field cron schedule, with run history and output. |
| Database service | A managed Postgres or Redis bound to the project. |

Every service belongs to a project and an environment.
A project starts with a `production` environment; add `staging` or anything else you need.

## What a service has

- **Releases.** Every deploy is an immutable release with a number, a state and a reason when it fails.
- **Variables.** Sealed at rest, masked on read, and able to reference another service, a shared variable or a generated secret.
- **An address.** Every service is assigned a private name. A web service or static site can also have a public address.
- **Settings.** Replicas, region, start command, health check, restart policy, volumes and idle sleep.

## The lifecycle

1. Create the service with a source: a git repository, a container image or an uploaded archive.
2. Deploy it. MIOSA builds it and starts a release.
3. The release becomes `active` when its replicas pass their health checks.
4. Deploy again to change it, or roll back to an earlier release. Rollback serves the earlier built image, so nothing is rebuilt.

## Where to go next

- [Quick start](/docs/services/quickstart): a repository to a live URL, then Postgres, a worker, a domain and a rollback.
- [Services and types](/docs/services/services): the source, settings and address of each type.
- [Variables](/docs/services/variables): references between services and generated secrets.
- [Releases](/docs/services/releases): deploy, promote, roll back and cancel.
- [CLI](/docs/services/cli) and [SDKs](/docs/services/sdk): the same operations from a terminal or code.

## Migrating from Railway

The model maps directly:

| Railway | MIOSA |
|---|---|
| Project | Project |
| Service | Service (web service, worker, private service or static site) |
| Environment | Environment |
| Deployment | Release |
| Variables and shared variables | Variables and shared variables |
| Custom domain | Public address |

`miosa service` operates Services.
Services use `/projects/:id/services` and `/services/:id`; the separate Deploy product keeps its own `/deployments` routes.

# Preview environments

URL: https://miosa.ai/docs/services/previews
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/previews
Source: src/routes/docs/services/previews/+page.md
Description: Open a pull request and MIOSA deploys it to its own environment with its own addresses, then removes it when the pull request closes.

# Preview environments

A preview environment is a copy of your project's default environment that runs a pull request.
Open a pull request and MIOSA creates the environment, deploys the pull request's branch, and comments the addresses on the pull request.
Close or merge it and the environment is deleted.

## What happens

| Pull request event | What MIOSA does |
|---|---|
| Opened or reopened | Forks the default environment as `pr-<number>`, deploys every service from the pull request's branch, and comments the addresses |
| New commit pushed | Redeploys the services of `pr-<number>` |
| Closed or merged | Deletes `pr-<number>` and nothing else |

Each server service in the preview is named `<service>-pr-<number>`.
Variables are copied from the environment it was forked from.
A preview never changes the environment it came from.

## Turn it on

Open the project's **Settings** in the console and choose **Previews**.
Set the repository as `owner/name`, switch previews on, and save.
The page shows the webhook URL and the secret to paste into GitHub.

In the GitHub repository, add a webhook:

| Field | Value |
|---|---|
| Payload URL | The URL shown in Previews, `https://api.miosa.ai/api/v1/hooks/git/<project id>` |
| Content type | `application/json` |
| Secret | The secret from Previews |
| Events | Pull requests only |

The repository you set must match GitHub's `full_name` exactly, or deliveries are ignored.
A delivery is accepted only when its signature matches the secret.
The secret is write-only: it is never shown again, so keep a copy or set a new one.

## Cost control

| Setting | Default | Range |
|---|---|---|
| `max_open` | 3 | 1 to 20 |
| `ttl_hours` | 72 | 1 to 720 |

A fourth preview is refused while three are open.
A preview for a pull request nobody closed is deleted after 72 hours.
Raise or lower both in Previews.

## From the API

```text
GET    /api/v1/projects/:id/previews
PUT    /api/v1/projects/:id/previews
DELETE /api/v1/projects/:id/previews/:preview_id
```

`PUT` replaces the row, so send the whole object: `{repository, enabled, max_open, ttl_hours, secret}`.
A blank or absent `secret` keeps the one already stored.
The row you get back reports `has_secret`, never the secret, and the `webhook_path` to use.
These routes need the `projects:read` and `projects:write` scopes.

## Where to go next

- [Environments](/docs/services/environments): fork an environment by hand.
- [Variables](/docs/services/variables): what a preview copies.

# Protection and WAF

URL: https://miosa.ai/docs/services/protection
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/protection
Source: src/routes/docs/services/protection/+page.md
Description: Put a password in front of a service, mint share links, and set the web application firewall rules the proxy enforces.

# Protection and WAF

Protection and the WAF are enforced at the edge, in front of the service, so they
apply before a request reaches your process.

## Password and share links

```bash
miosa protection shop API                            # is it protected?
miosa protection shop API --password 'open-sesame'
miosa protection shop API --share-link --expires 3600
miosa protection shop API --revoke <link-id>
miosa protection shop API --off
```

The password is never shown again. A share link is a way past it for one person:
the `msl_...` token is shown once, and expires after `--expires` seconds (seven
days by default, at most ninety). A visitor uses it as `?miosa_share=<token>` or
with an `x-miosa-share-token` header.

Protection can also be set on a Deploy target or on an environment kind, and the
rows resolve service over environment over kind. That is why a preview environment
can be protected without touching each service in it.

## WAF

```bash
miosa waf shop API
miosa waf shop API --mode enforce --deny 203.0.113.0/24 --rate 120
miosa waf shop API --allow 198.51.100.0/24
miosa waf shop API --attack-mode on
miosa waf shop API --off
```

- `--mode` is `off`, `observe` or `enforce`.
- `--allow`/`--deny` take IPs or CIDRs (`ip_allow`/`ip_deny` on the wire).
- `--rate` is requests per minute per source; `0` clears the limit.
- `--attack-mode` serves a JavaScript challenge to browsers and `403` to
  everything else.

**Country rules read only the trusted `x-miosa-country` header that the edge
sets.** There is no GeoIP lookup of our own: if a request arrives without that
header the country rules are skipped, and the WAF document says whether they can
act at all with `country_rules_active`.

Run `--mode observe` for a day first. The WAF reports what it would have blocked,
so you can see a wrong CIDR before it turns into a page full of 403s.

# Services quick start

URL: https://miosa.ai/docs/services/quickstart
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/quickstart
Source: src/routes/docs/services/quickstart/+page.md
Description: Take a repository to a live URL, add Postgres and Redis, add a worker, attach a domain, read a failed release and roll back.

# Services quick start

This walkthrough takes a repository to a live URL, then adds a database, a worker and a domain.
Every step has a CLI form and an SDK form.

## Before you start

- A MIOSA account with an API key (`msk_...`) or a signed-in CLI.
- A project. `miosa project create shop --workspace-id <workspace>` creates one; `miosa project list` shows the others.
- A repository MIOSA can clone, or a container image.

Export the key once:

```bash
export MIOSA_API_KEY=msk_your_key
```

## 1. Create a web service

```bash
miosa service create shop API --type web \
  --repo https://github.com/acme/api \
  --branch main \
  --start-command "node server.js" \
  --replicas 2 \
  --env NODE_ENV=production
```

`--type web` stores the API's `server` kind, which can have a public address.
`--type private` stores the same kind but never gets one.
The command prints the service, its private address and, once enabled, its public address.

TypeScript:

```typescript
const service = await miosa.services.create(projectId, {
  name: "API",
  type: "web",
  source: { type: "git", ref: "https://github.com/acme/api", branch: "main" },
  settings: { start_command: "node server.js", replicas: 2 },
});
const address = await miosa.services.enablePublicAddress(service.id);
console.log(address.url); // https://api.acme.miosa.app
```

Python:

```python
service = miosa.services.create(
    project_id,
    "API",
    type="web",
    source={"type": "git", "ref": "https://github.com/acme/api", "branch": "main"},
    settings={"start_command": "node server.js", "replicas": 2},
)
address = miosa.services.enable_public_address(service["id"])
print(address["url"])
```

## 2. Deploy it

```bash
miosa service deploy shop API --message "first deploy" --wait
```

`--wait` polls the release until it is live or fails.
Without it you get the queued release and can check it with `miosa service releases shop API`.

```typescript
const release = await miosa.services.deploy(service.id, { message: "first deploy" });
let current = release;
while (!["active", "sleeping", "failed", "canceled", "stopped", "removed"].includes(current.state)) {
  await new Promise((resolve) => setTimeout(resolve, 3000));
  current = await miosa.services.release(service.id, release.id);
}
console.log(current.state);
```

The Python SDK ships `wait_for_release(service_id, release_id)`, which polls and raises on a failed release.

A release goes `queued -> building -> built -> starting -> health_check -> active`.
Any step can fail; the release carries a `reason.code` such as `build_failed`, `healthcheck_timeout` or `no_capacity`.

## 3. Add Postgres and Redis

Templates create the service, its variables and the references between them in one change set:

```bash
miosa service templates                       # the catalog
miosa service templates apply shop nextjs-postgres
miosa service templates apply shop redis
```

The Postgres template creates a database service and a web service whose `DATABASE_URL` is the reference `${{Postgres.DATABASE_URL}}`.
Applying a template stages one change set and deploys every service it creates; pass `--no-deploy` to create them without deploying.

To read the connection string later:

```bash
miosa service connection shop Postgres
```

That call needs `databases:read` and is audited, because the URL holds the password.

## 4. Add a worker

A worker has no port and no address.

```bash
miosa service create shop Worker --type worker \
  --repo https://github.com/acme/api \
  --start-command "node worker.js" \
  --replicas 1
miosa service deploy shop Worker
```

The worker can read the same database with the same reference:

```bash
miosa service vars set shop Worker DATABASE_URL='${{Postgres.DATABASE_URL}}'
```

## 5. Attach a domain

A web service or static site gets a public address on `miosa.app`:

```bash
miosa service domains shop API
miosa service domains enable shop API --label api
```

The result is `https://api.<your-org>.miosa.app`, served from the active release's healthy replicas.
To stop serving publicly without deleting the service, remove the address:

```bash
miosa service domains disable shop API
```

Private networking between services is not available yet, so other services call it at its public address; databases are reached through their connection variables, see [addresses and domains](/docs/services/domains/).

## 6. Read a failed release

```bash
miosa service releases shop API
miosa service logs shop API
```

`logs` prints the newest release's state transitions and its failure reason.
Pass `--release <number>` to look at an older one.
The console's Logs tab shows each replica's runtime lines and the build log; see [Logs](/docs/services/logs).

## 7. Roll back

Rollback serves an earlier release's built image with its frozen source and settings.
Nothing is rebuilt, so it is fast.

```bash
miosa service rollback shop API 3 --yes
```

`miosa service promote shop API 3` is the same call: the Services API calls the operation rollback.

## 8. Tear down

```bash
miosa service stop shop API --yes      # stop now, keep the service
miosa service delete shop API --yes    # remove it and stop its replicas
```

Deleting a database service also deletes its data, so it takes `--confirm <exact name>` instead of `--yes`.
See [Deleting a database service](/docs/services/cli#deleting-a-database-service).

# Services releases

URL: https://miosa.ai/docs/services/releases
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/releases
Source: src/routes/docs/services/releases/+page.md
Description: Deploy a service, follow the release state machine, read a failure reason, promote or roll back, and cancel a release.

# Services releases

A release is one build-and-serve attempt of a service.
It is immutable: it freezes the source, the settings and the built image it ran with.

## Deploy

```bash
miosa service deploy shop API                        # rebuild the service's own source
miosa service deploy shop API --dir . --wait         # upload a directory
miosa service deploy shop API --repo https://github.com/acme/api --branch main
miosa service deploy shop API --image ghcr.io/acme/api:1.4 --port 8080
```

Every release takes an `Idempotency-Key`; the CLI sends one so a retried command returns the first release instead of starting a second.

`--wait` follows the release and exits non-zero if it fails, printing the reason.

## The state machine

| State | Meaning |
|---|---|
| `queued` | Accepted, waiting for a worker. |
| `building` | The source is being built. |
| `built` | The image exists; the release is about to start replicas. |
| `pre_deploy` | `pre_deploy_command` is running in the new replica. |
| `starting` | Replicas are booting. |
| `health_check` | The health path is being probed. |
| `active` | Serving. |
| `sleeping` | Idle sleep stopped the replicas; the next request wakes them. |
| `draining` | An earlier release is stopping. |
| `crashed` | A replica crashed and the restart policy did not recover it. |
| `failed` | Terminal failure, with a reason. |
| `canceled` | Canceled by a user. |
| `stopped` | Stopped by `stop`. |

A release that never leaves a state before its deadline is settled by the reaper with `deadline_exceeded`.

## Read a failure

```bash
miosa service releases shop API
miosa service logs shop API
miosa service logs shop API --release 6
```

`logs` prints every transition and the failure reason of the newest release, or of the release you name.
The release events carry the reason a release failed.
The build log and each replica's runtime lines are in the console's Logs tab; see [Logs](/docs/services/logs). The CLI does not stream them.

What a running replica printed is a separate read:

```text
GET /projects/:id/services/:sid/logs                    # the active release
GET /projects/:id/services/:sid/deployments/:did/logs   # one release
```

Each returns the last lines of every replica's output, with your secret values masked.
`tail` sets the number of lines (1 to 1000, default 200) and `replica` narrows it to one replica.
A replica that cannot be read says so in its own entry and does not hide the others.
It is a snapshot, not a stream.

Common reason codes:

| Code | What to do |
|---|---|
| `build_failed` | Read the build output; the command exited non-zero. |
| `clone_failed` | The repository or branch was not reachable, or the credential is wrong. |
| `image_pull_failed` | The image reference is wrong, or the registry secret is missing. |
| `healthcheck_timeout` | The app did not answer its health path in time. Check `start_command` and the port. |
| `pre_deploy_failed` | `pre_deploy_command` exited non-zero; nothing serves. |
| `no_capacity` | No host had room for the shape in that region. Try another region or a smaller `limits`. |
| `reference_missing` | A variable references something that does not exist. `miosa service vars effective` lists them. |
| `reference_cycle` | Two variables reference each other. |
| `deadline_exceeded` | The release sat in one state too long and the reaper settled it. |
| `quota_exceeded` | A plan limit was reached. |

## Promote and roll back

Rollback serves an earlier release's built image with its frozen source and settings.
Nothing is rebuilt, so it is fast.

```bash
miosa service rollback shop API 3 --yes
miosa service promote  shop API 3 --yes   # the same call
```

The Services API has one operation for this and calls it rollback.
The CLI accepts `promote` as its name for "serve this release again"; there is no separate promote route.

## Cancel and remove

```bash
miosa service cancel shop API 7     # a queued or building release
miosa service release shop API 3    # one release
```

A release that already finished can be removed from the history; one that is still running cannot.

## Stop, start, restart

```bash
miosa service stop    shop API --yes   # stop every active release now
miosa service start   shop API         # start a stopped service
miosa service restart shop API         # queue a release that restarts it
```

`stop` fails with `SERVICES_NOT_STOPPED` if a replica cannot be stopped, so a service is never reported stopped while it still runs.
`start` on a service that is already running or starting is `SERVICE_CONFLICT`.

## Rollout and rollback of several services

Each service releases independently.
For a coordinated change, apply a template or a change set, which stages every service's change and deploys them together.

# Services replicas and scaling

URL: https://miosa.ai/docs/services/replicas
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/replicas
Source: src/routes/docs/services/replicas/+page.md
Description: Set how many replicas a service runs, where, and how large they are, and what a scale change does to the running release.

# Services replicas and scaling

A replica is one running copy of a service.
A service runs from 1 to 50 replicas.

## Change replicas, region and size

```bash
miosa service update shop API --replicas 4
miosa service scale  shop API --replicas 4
```

`update` changes the setting.
`scale` changes replicas, region or limits and also queues a release that applies them.
The running release is not touched until that release is active, so a scale change never interrupts traffic part way.

| Setting | Meaning |
|---|---|
| `replicas` | 1 to 50. A writable volume forces 1. |
| `region` | `us-west`, `us-east` or `us-mia`. |
| `limits` | `{vcpu, memory_mb}`. Above 4 vCPU or 8192 MB the release fails. |
| `restart_policy` | `always`, `on_failure` or `never`. |
| `healthcheck_path` | The path a web service must answer before a new release becomes active. |

## What a release does to replicas

A new release starts its replicas first.
Once they pass the health check, the release becomes `active` and the earlier release drains and stops.
`overlap_s` and `terminate_grace_s` add time before the earlier release stops.

## Volumes

A volume is attached to a service, never added on its own.
A writable volume allows one replica.
Mount it read-only if you need more.
A service can mount up to four volumes, and a path or a volume cannot repeat.

## Check what takes effect

```bash
miosa service settings shop
```

Each setting is `enforced`, `stored` or `unsupported`.
A `stored` setting is kept but not applied yet, so do not rely on it.

## Where to go next

- [Releases and rollback](/docs/services/releases): how a scale change becomes a release.

# Services SDKs

URL: https://miosa.ai/docs/services/sdk
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/sdk
Source: src/routes/docs/services/sdk/+page.md
Description: TypeScript and Python methods for services, releases, variables, addresses and projects.

# Services SDKs

Both SDKs expose the same operations.
The TypeScript SDK lives on `miosa.services` and `miosa.projects`; the Python SDK on `miosa.services` and `miosa.projects` (sync and async).

Product types are accepted everywhere the API takes a kind:

```typescript
await miosa.services.create(projectId, { name: "API", type: "web" });
```

`web` and `private` both store `kind: server`; pass `kind` when you already speak the API.

## Services

| Method | Route |
|---|---|
| `list(projectId, { environment })` | `GET /projects/:id/services` |
| `get(serviceId)` | `GET /services/:id` |
| `create(projectId, params)` | `POST /projects/:id/services` |
| `update(serviceId, params)` | `PATCH /services/:id` |
| `delete(serviceId)` | `DELETE /services/:id` |
| `deploy(serviceId, params)` | `POST /services/:id/deployments` |
| `redeploy(serviceId)` | `POST /services/:id/redeploy` |
| `restart(serviceId)` | `POST /services/:id/restart` |
| `start(serviceId)` | `POST /services/:id/start` |
| `stop(serviceId)` | `POST /services/:id/stop` |
| `scale(serviceId, params)` | `POST /services/:id/scale` |
| `releases(serviceId)` | `GET /services/:id/deployments` |
| `release(serviceId, releaseId)` | `GET /services/:id/deployments/:did` |
| `events(serviceId, releaseId)` | `GET /services/:id/deployments/:did/events` |
| `rollback(releaseId)` | `POST /service-deployments/:id/rollback` |
| `redeployRelease(releaseId)` | `POST /service-deployments/:id/redeploy` |

| `deleteVariables(serviceId, names)` | `DELETE /services/:id/variables/:name` |
| `effectiveVariables(serviceId)` | `GET /services/:id/variables/effective` |
| `revealVariable(serviceId, name)` | `GET /services/:id/variables/:name/reveal` |
| `enablePublicAddress(serviceId, label?)` | `PUT /services/:id/public-address` |
| `disablePublicAddress(serviceId)` | `DELETE /services/:id/public-address` |

| `runs(serviceId)` | `GET /services/:id/runs` |
| `settingCapabilities(projectId)` | `GET /projects/:id/services/setting-capabilities` |
| `createSourceUpload(params)` | `POST /uploads` |

The Python names are snake_case (`set_variables`, `enable_public_address`, ...), and `wait_for_release(service_id, release_id)` polls a release and raises `MiosaError` with code `RELEASE_FAILED` or `RELEASE_TIMEOUT`.

|---|---|
| `list({ workspaceId })` | `GET /projects` |
| `get(projectId)` | `GET /projects/:id` |

| `templates()` | `GET /project-templates` |
| `template(slug)` | `GET /project-templates/:slug` |
| `applyTemplate(projectId, slug, params)` | `POST /projects/:id/templates/:slug/apply` |

## Examples

TypeScript:

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const project = await miosa.projects.create({
  name: "Shop",
  workspaceId: process.env.MIOSA_WORKSPACE_ID!,
});

const api = await miosa.services.create(project.id, {
  name: "API",
  type: "web",
  source: { type: "git", ref: "https://github.com/acme/api" },
  settings: { start_command: "node server.js", replicas: 2 },
});

await miosa.services.enablePublicAddress(api.id);
const release = await miosa.services.deploy(api.id, { message: "first deploy" });
console.log(release.number, release.state);
```

Python:

```python
from miosa import Miosa

miosa = Miosa(api_key=os.environ["MIOSA_API_KEY"])

project = miosa.projects.create("Shop", workspace_id=os.environ["MIOSA_WORKSPACE_ID"])

api = miosa.services.create(
    project["id"],
    "API",
    type="web",
    source={"type": "git", "ref": "https://github.com/acme/api"},
    settings={"start_command": "node server.js", "replicas": 2},
)

miosa.services.enable_public_address(api["id"])
release = miosa.services.deploy(api["id"], message="first deploy")
live = miosa.services.wait_for_release(api["id"], release["id"])
print(live["state"])
```

## Async

The Python SDK has the same surface under `AsyncMiosa`, with `await` on every method and an async `wait_for_release`.

# Services and types

URL: https://miosa.ai/docs/services/services
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/services
Source: src/routes/docs/services/services/+page.md
Description: The source, settings, address and limits of a web service, worker, private service, static site, cron job and database service.

# Services and types

A service's `kind` is what the API stores.
It is one of `server`, `worker`, `cron`, `static` or `database`.
The product types map onto it:

| Product type | `kind` | Public address |
|---|---|---|
| Web service | `server` | Yes, when enabled |
| Private service | `server` | No |
| Worker | `worker` | No |
| Static site | `static` | Yes, when enabled |
| Cron job | `cron` | No |
| Database service | `database` | No (use `connection`) |

There is no `web` or `private` kind.
The CLI and both SDKs take `type: web` or `type: private`, and store `kind: server`.
A private service is a server service with no public address.

## Source

A service builds from one source.

| `source.type` | What it needs | Notes |
|---|---|---|
| `git` | `ref` (repository URL), optional `branch` and `root_dir` | Built on a Services build cell |
| `image` | `ref` (OCI image), optional `port`, optional `registry_secret` | The image is run as-is |
| `upload` | `upload_id` | PUT a `.tar.gz`, `.tar.zst`, `.tar` or `.zip` archive first |
| `forge` | `ref` | A repository hosted by MIOSA Forge |

Dockerfile builds run on the Services build cells and are detected in the source.
While the build cells are off, a Dockerfile service does not build; use a git build or an image source.

Uploading a directory is one command:

```bash
miosa service deploy shop API --dir . --wait
```

The CLI packs the directory (skipping `.git`, `node_modules` and `.env*`), records the archive with `POST /uploads`, PUTs it to the returned URL and deploys `{source: {type: "upload", upload_id}}`.
Archives are single use and expire after an hour.

## Settings

Settings are validated strictly: an unknown key is refused, so a typo never silently stays.

| Setting | Applies to | Meaning |
|---|---|---|
| `start_command` | all | Replaces the image entrypoint when a replica starts. |
| `pre_deploy_command` | all | Runs once in the new replica before the app starts. A non-zero exit fails the release. |
| `healthcheck_path` | `server` | The path probed before a new release becomes active. |
| `healthcheck_timeout_s` | `server` | How long a release may take to pass. |
| `restart_policy` | all | `always`, `on_failure` or `never`. |
| `max_retries` | all | Restarts before an `on_failure` replica is left stopped. |
| `replicas` | all | 1 to 50. A writable volume forces 1. |
| `region` | all | `us-west`, `us-east` or `us-mia`. |
| `limits` | all | `{vcpu, memory_mb}`. Above 4 vCPU or 8192 MB the release fails. |
| `sleep` | services with a public address | `{enabled, idle_s}`. The next request wakes the service. |
| `cron_schedule` | `cron` | Required. Five-field cron, UTC. |
| `overlap_s` | all | Extra time before the previous release is stopped. |
| `terminate_grace_s` | all | Extra time before the previous release is stopped, like `overlap_s`. |
| `volumes` | `server`, `worker` | Up to four `{volume, mount_path, read_only}`. |

Read what each setting actually does on your platform:

```bash
miosa service settings shop
```

Each entry is `enforced` (it takes effect), `stored` (kept but not applied yet) or `unsupported`.
Never present a `stored` setting as if it took effect.

## Create and change

```bash
miosa service create shop API --type web --repo https://github.com/acme/api --replicas 2
miosa service update shop API --replicas 4
miosa service scale  shop API --replicas 4        # also queues a release
```

`update` merges settings: only the flags you pass change.
It sends the `lock_version` it read; a stale value is refused with `STALE_SERVICE` so two editors cannot overwrite each other.
`scale` changes replicas, region or limits and queues a release that applies them.

## Cron jobs

```bash
miosa service create shop Nightly --type schedule \
  --repo https://github.com/acme/api \
  --start-command "node jobs/nightly.js" \
  --schedule "0 3 * * *"
miosa service runs shop Nightly --output
```

`runs` shows the newest 20 runs with state, exit code, times and output.
A run is limited to five minutes.

## Database services

A database service is a managed Postgres or Redis bound to the project.
Apply a template to create one with its variables wired, or attach an existing managed database.
The connection string is only available through `connection`, which is audited:

```bash
miosa service connection shop Postgres
```

## Limits and errors

| Error | Meaning |
|---|---|
| `SERVICE_NOT_FOUND` | No service with that id in the project. The API resolves services by id only. |
| `STALE_SERVICE` | The `lock_version` you sent is older than the stored one. Re-read and retry. |
| `SERVICE_CONFLICT` | `start` on a service that is already running or starting. |
| `SERVICES_NOT_STOPPED` | `stop` could not stop a replica; the service stays running. |
| `INGRESS_DISABLED` | Public addresses are off for this platform; the service runs but has no address to reach it on. |
| `PLAN_LIMIT_REACHED` | The plan's service limit is reached. |

# Static sites from Git

URL: https://miosa.ai/docs/services/static
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/static
Source: src/routes/docs/services/static/+page.md
Description: Build a static site from a repository and serve it from the static lane, with an optional build command and output directory.

# Static sites from Git

A static service takes a git source like a web service does, and is served from
the static lane instead of a container.

```bash
miosa service create shop site --type static \
  --repo https://github.com/acme/site --branch main
miosa service update shop site --build-command "npm run build" --output-dir dist
```

## How the site is built

The build runs on a build cell: Railpack detects the framework, or a Dockerfile
in the repository is used when there is one. `build_command` replaces the build
command Railpack would use (Railpack builds only), and `output_dir` says which
folder to serve.

With neither set, the output folder is discovered: Railpack's own static root
first, then `dist`, `build`, `out`, `public` and `_site`, taking the first one
with an `index.html` at its top. A Dockerfile build also tries the image's own
document root (`nginx`, `httpd`, `caddy`).

## When the build fails

- `reason_code: build_failed` with `reason_detail` starting
  `static_output_missing:` means no `index.html` was found in any candidate
  folder. Set `output_dir` to the folder your build writes.
- `static_site_too_large:` means the site is over 500 MiB or over 20,000 files.

A Vite site needs nothing: Railpack detects Vite, builds it, and the output is
`dist`. Single-page-app fallback routing is a separate change; until then a deep
link into a client-side route should be handled by the app.

# Services variables

URL: https://miosa.ai/docs/services/variables
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/services/variables
Source: src/routes/docs/services/variables/+page.md
Description: Set a service's variables, reference another service's, share variables across an environment, and generate secrets.

# Services variables

Variables are stored sealed at rest.
A read returns a masked preview, never the value.
The only plaintext read is `reveal`, which needs `env:reveal` and a person's own credential, and which refuses a sealed variable.

## Set a variable

```bash
miosa service vars set shop API NODE_ENV=production
miosa service vars list shop API
```

TypeScript:

```typescript
await miosa.services.setVariables(serviceId, { NODE_ENV: "production" });
const variables = await miosa.services.variables(serviceId);
```

Python:

```python
miosa.services.set_variables(service_id, {"NODE_ENV": "production"})
variables = miosa.services.variables(service_id)
```

A write merges by name. Deleting takes names:

```bash
miosa service vars unset shop API NODE_ENV,OLD_FLAG
```

## References

A value may be a reference.
MIOSA resolves it when the release starts, so the service always sees the current value.

| Expression | Resolves to |
|---|---|
| `${{Postgres.DATABASE_URL}}` | A variable of another service in the same environment |
| `${{shared.API_BASE}}` | An environment shared variable |
| `${{NAME}}` | Another variable of the same service |
| `${{secret(32)}}` | A generated random secret of 32 characters |

```bash
miosa service vars set shop API DATABASE_URL='${{Postgres.DATABASE_URL}}'
```

Quote the value in a shell so `${{...}}` reaches MIOSA unchanged.

A cycle or a malformed expression is refused with every problem at once, and nothing is written.
A reference to a service or variable that does not exist yet is allowed to be saved, but it blocks the deploy and shows up under `problems`.

## Shared variables

Shared variables belong to the environment and are visible to every service in it.

```bash
miosa project vars set shop API_BASE=https://api.acme.dev
miosa project vars list shop
miosa project vars unset shop API_BASE
```

A service reads one with `${{shared.API_BASE}}`.

## When a change needs a release

Writing a variable does not change the running release.
MIOSA records what the write made stale on the service document as `pending_changes`:

```json
{"needs": "rebuild", "variables": ["DATABASE_URL"], "because": "Web.DATABASE_URL", "at": "..."}
```

- `needs: rebuild` when a build-visible variable changed, because a redeploy alone would ship the value inlined at build time.
- `needs: redeploy` for every other variable, which is read when the release starts.
- `because` is `own`, `shared`, or the reference that carried the change: changing `Web.DATABASE_URL` marks every service whose expression uses it, and changing a shared variable marks every service that reads it.

```bash
miosa service get shop API
```

A deploy clears the mark, and a rebuild is never downgraded by a later runtime change:

```bash
miosa service deploy shop API
```

## Check what a deploy will receive

```bash
miosa service vars effective shop API
```

This shows every variable the release will receive, with references resolved and values still masked, plus a `problems` list.
A release is refused while that list is not empty.

## Read one value

```bash
miosa service vars reveal shop API DATABASE_URL
```

Reveal is for a person acting as themselves.
A sealed variable never reveals, and every reveal is audited with the variable's name and never its value.

## Build-time variables

A variable can be marked build-visible, so the build sees it too.
Platform-provided values are never sent to a build.
Names starting with `MIOSA_` or `RAILPACK_` are reserved.

# SOMA

URL: https://miosa.ai/docs/soma
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/soma
Source: src/routes/docs/soma/+page.md
Description: SOMA is MIOSA's own open-source virtual machine monitor, written in Rust. It gives every sandbox a hardware-isolated machine with its own Linux kernel, restored from a certified snapshot.

# SOMA

SOMA is the Secure Optimized Machine Architecture: the virtual machine monitor MIOSA builds and runs its sandboxes on.
It is open source under the Apache License 2.0 at [Miosa-osa/SOMA](https://github.com/Miosa-osa/SOMA), it is written in Rust, and it runs on Linux KVM.

A SOMA sandbox is not a container and not a userspace kernel.
It is one hardware-isolated Linux virtual machine with its own guest kernel and its own private memory, created and owned by a single VMM process for exactly one sandbox lifetime.

MIOSA runs SOMA for you. This page explains what sits under the Sandboxes and Computers you already create.
If you only want the API switch that selects a runtime, read [Choosing a runtime](/docs/soma/choosing-a-runtime/).

## What SOMA is

SOMA is a type-2 VMM for Linux guests, plus the launch runtime around it.
It boots a pinned Linux kernel directly through the paravirtualized PVH entry, so there is no BIOS or UEFI stage, and it exposes a deliberately tiny virtual machine to the guest.

Three things follow from that design:

- **Hardware isolation, per sandbox.** The guest runs on virtual CPUs backed by KVM. It is a real kernel with its own page tables, not a syscall filter or a sandboxed process.
- **A small, fixed machine.** SOMA machine contract v1 exposes at most five virtio devices and no PCI bus at all. Smaller device surface means fewer places for a hostile guest to attack.
- **Start from a certified snapshot, not from a power-on.** The expensive work happens once, when a Generation is built. Launch restores a warmed machine and then proves the guest is alive.

SOMA is not a container runtime, a provider control plane, or a billing system.
MIOSA's platform owns placement, tenancy, policy, and the public sandbox API, and SOMA sits underneath that as the execution engine.

## Why we built it

MIOSA's sandboxes ran on Firecracker, and Firecracker is still the default today (see [Choosing a runtime](/docs/soma/choosing-a-runtime/)).
We built SOMA because we wanted to own the whole launch path, especially the exact moment a machine becomes command-ready, and because we wanted an engine whose contract carries no cloud, provider, or fixed machine-size assumption.

The goals come straight from [the project's mission](https://github.com/Miosa-osa/SOMA/blob/main/MISSION.md):

- One native VMM process owns one virtual machine.
- Restored memory uses immutable shared backing with private copy-on-write mappings instead of eagerly copying a whole RAM image.
- Every restore gets a fresh identity, entropy state, network identity, and repaired clock.
- Ready means an authenticated guest agent completed a real command after repair, not that a socket opened.
- Public contracts contain no cloud, provider, billing tier, or fixed machine-size assumption.

## How it works

Read the stack from the workload down to the hardware.
Each layer uses the layer below it, and the guest never talks to KVM or to physical hardware directly.

### Build time: Template, Generation, Instance

SOMA separates the slow work from the fast work.

1. A **Template** (a TOML recipe) is compiled into a **Template Lock** that pins the image to an exact OCI digest.
2. The Generation compiler turns that lock and the normalized root filesystem into an immutable **Generation**: one certified box that never runs itself.
3. Every **Launch** of that Generation opens a private **Instance**, a running machine with its own identity, memory, and disk head.

A Generation carries its own pinned kernel, a read-only root filesystem, a sterile writable-disk template, an initramfs, and a signed-off manifest.
Its identity, the Generation ID, is the SHA-256 of that manifest.
Because the manifest names every artifact by digest, two Instances of the same Generation are byte-identical at the moment they start but never share mutable state.

Shape is a build parameter, not a per-request knob.
A Generation is compiled for exactly one CPU, memory, and disk shape, and a Launch asserts that shape rather than choosing it.
That is what lets the memory image be captured once and restored many times.

### Launch time: claim, restore, repair, prove

The fast path is short by construction:

Diagram:
flowchart LR
    A["Validate Generation identity"] --> B["Claim a prepared worker"]
    B --> C["Map memory copy-on-write"]
    C --> D["Create KVM machine and restore state"]
    D --> E["Resume and repair the guest"]
    E --> F["Authenticate soma-guest over vsock"]
    F --> G["Run the readiness command"]

- **Prepared workers.** A node-local allocator keeps a bounded pool of already-booted machines, so a Launch usually claims one through a single-winner exchange rather than booting from scratch.
- **Copy-on-write memory.** The restored memory is shared read-only and mapped privately per Instance. One Generation can back many Instances without copying its RAM each time.
- **Repair before Ready.** A restored guest is a clone, so SOMA gives it fresh identity, fresh entropy, a fresh network identity, and a corrected clock. Readiness is only reported after the in-guest agent authenticates over vsock and completes a real command.
- **No shell.** Commands cross the boundary as argument vectors, not shell strings, and output comes back as explicit bytes.

Everything on the launch path is bounded: time, output size, and the number of control responses.

### The device surface

SOMA machine contract v1 exposes at most five modern virtio 1.0+ devices, each on its own fixed virtio-mmio version 2 page:

| Device | Present when |
|---|---|
| Immutable root block (EROFS) | Always |
| Private writable overlay block | Writable storage is declared |
| vsock (control and commands) | Always |
| Entropy | Always, so a restore is never reused |
| Network | A network capability is declared |

There is no PCI bus, no device hotplug, no graphics, no USB, and no BIOS.
The device set is part of the Generation's identity, so a snapshot captured on a machine with an overlay can never be restored onto one built without it.
That mismatch is refused before a single byte of memory is mapped.

### Isolation and evidence

One `soma-vmm` process owns one machine, and that process runs inside a jail with a narrowed syscall filter.
The guest is treated as hostile: every length, offset, descriptor, and protocol frame it sends is validated on the host side.
Each terminal operation returns an execution receipt that names the immutable workload, the effective isolation class, the preparation class, the result, the timing boundary, and the cleanup state.
If a dimension cannot be proven, the receipt says so instead of inventing a value.

## SOMA and Firecracker

Firecracker is a strong, well-understood microVM monitor, and MIOSA ran on it for years.
SOMA exists because we wanted a machine we could shape end to end, from the kernel boot entry to the readiness proof.
Both are Rust VMMs on KVM; the difference is the contract wrapped around the machine.

|  | SOMA | Firecracker |
|---|---|---|
| Built by | MIOSA, open source | AWS, open source |
| Language | Rust | Rust |
| Isolation | KVM; one process per machine | KVM; one process per microVM |
| Guest kernel | One pinned kernel per sandbox | One kernel per microVM |
| Boot entry | PVH; no BIOS or UEFI | Project kernel policy |
| Device model | Five virtio-mmio devices; no PCI | Small model; virtio over MMIO |
| Host hardening | Jailed VMM; seccomp; cgroups | Jailer; seccomp; cgroups |
| Warm start | Restore into a prepared worker | Snapshot restore |
| Startup numbers | Admission targets, not claims | Project performance specification |
| Contract around the VM | Identity repair, readiness, receipts | Mechanisms only |

Neither "startup numbers" cell is a head-to-head result.
Firecracker's own performance specification defines a typical API wall time of 12 ms, guest-init boot at or below 125 ms, and VMM overhead at or below 5 MiB.
SOMA's admission targets are lower still, below 5 ms server-side create and below 10 ms to first command, but they are targets for a path that is still being certified rather than measured results.
Firecracker's spec also does not include restore-time identity repair or an authenticated readiness proof, which is the gap SOMA was built to close.

MIOSA's own published number is a product-level figure, not an engine figure.
In the independent ComputeSDK burst benchmark on 2026-10-23, MIOSA ranked first of 32 providers with a median burst time-to-interactive of 57.09 ms.
See [Benchmarks](/docs/benchmarks/) for every run and the raw JSON.

## Open source

SOMA is public and licensed under the [Apache License 2.0](https://github.com/Miosa-osa/SOMA/blob/main/LICENSE), the same license as Firecracker. The repository also carries a [NOTICE](https://github.com/Miosa-osa/SOMA/blob/main/NOTICE) file (Copyright 2026 MIOSA LLC), and the workspace declares the license the same way.
The MIOSA and SOMA names and logos are covered separately by [BRAND.md](https://github.com/Miosa-osa/SOMA/blob/main/BRAND.md).

The repository is honest about where it stands: the source version is `1.0.0-alpha.1`, and the project keeps a [claim ledger](https://github.com/Miosa-osa/SOMA/blob/main/docs/claim-ledger.md) that labels every capability as designed, component-tested, live-proved, integrated, or production-admitted, with the evidence for each.

To try it on your own machine, the supported local path today is Docker Desktop on macOS or Docker Engine on Linux, and the custom KVM engine wants a Linux host with `/dev/kvm`:

```sh
git clone https://github.com/Miosa-osa/SOMA.git
cd SOMA
cargo run --locked -p soma-cli -- doctor
cargo run --locked -p soma-cli -- --backend docker run node:22 -- /usr/local/bin/node --version
```

To contribute, start with [CONTRIBUTING.md](https://github.com/Miosa-osa/SOMA/blob/main/CONTRIBUTING.md) and [MISSION.md](https://github.com/Miosa-osa/SOMA/blob/main/MISSION.md).
A Rust change is expected to pass formatting, clippy with warnings denied, and the full workspace test suite.
Security findings go through the private process in [SECURITY.md](https://github.com/Miosa-osa/SOMA/blob/main/SECURITY.md), never a public issue.

## Status

SOMA is available to every customer.
Select the runtime on sandbox create, from the REST API, the SDKs, the CLI, or the console.
Firecracker (`standard`) remains the default.

`GET /api/v1/sandboxes/runtimes` lists the runtimes and what each one reports it supports today, so you can read SOMA's live capability flags before you choose it.

See [Choosing a runtime](/docs/soma/choosing-a-runtime/) for the create examples and the shape rules.

Known gaps today:

<!-- TODO(team-lead, before deploy): the SOMA persistence behavior below (default `persistent: false`, and a `422` when `persistent: true` is sent with SOMA) lands with #1993. Confirm #1993 is deployed before this branch ships. -->
- **Sandboxes are not persistent yet on SOMA.** State does not survive a stop or a timeout, and a disposable sandbox is deleted when its timeout expires: a SOMA create defaults to `persistent: false`, and `persistent: true` with SOMA is refused with a `422`.
- **Computers still run on Firecracker.** Only sandboxes expose a runtime choice.
- **No public per-sandbox engine latency figure.** The published benchmark is MIOSA's product-level burst number, not a breakout of SOMA's internal stages.
- **Feature parity is not complete.** SOMA's own claim ledger lists the capabilities that are integrated, live-proved, and still only designed.

  Pick SOMA or Firecracker on sandbox create, and see what each option requires.

## FAQ

**Is SOMA a fork of Firecracker?**
No. SOMA is an independent implementation, written from scratch in Rust against the Linux KVM interface and the virtio specification.

**Does my sandbox already run on SOMA?**
If you did not ask for a specific runtime, your sandbox runs on Firecracker, which is still the default. SOMA is available to every customer and is selected explicitly with `runtime_profile`. Either way the product contract, the API, and your data are identical.

**Can I run SOMA on my own hardware?**
Yes. The repository is public and Apache-2.0. Today the custom KVM engine requires a Linux host with `/dev/kvm`; Apple and Docker backends exist for local development.

**Does every sandbox get its own kernel?**
Yes. Each Instance boots its own copy of the Generation's pinned Linux kernel, so a kernel bug in one sandbox is not a shared kernel with its neighbors.

**Where do my containers fit?**
A SOMA sandbox is a virtual machine, so you can run a container runtime inside it. Inside the guest is your boundary; SOMA is the boundary around the guest.

**Is SOMA safe for untrusted production workloads?**
SOMA treats the guest as hostile and validates everything it sends, but the project is still labeled alpha. Treat it as a fast-moving engine you can inspect, not a finished audited product.

# Choosing a runtime

URL: https://miosa.ai/docs/soma/choosing-a-runtime
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/soma/choosing-a-runtime
Source: src/routes/docs/soma/choosing-a-runtime/+page.md
Description: Choose Firecracker, SOMA or auto when you create a sandbox with the runtime option. List the runtimes your organization offers and see what each runtime reports it supports today.

# Choosing a runtime

A sandbox runs on one of two engines: **Firecracker**, MIOSA's long-standing default, or **SOMA**, MIOSA's own open-source VMM.
Select one with the `runtime` option, which travels on the wire as the `runtime_profile` field.

If you never select a runtime, nothing changes. You get Firecracker (`standard`).
Organization and workspace runtime settings, with SOMA as the default, are coming.
SOMA is available to every customer.

## The runtimes

| Runtime | `runtime_profile` | What it is |
|---|---|---|
| Firecracker | `standard` | Full machine. The default for every size and template. |
| SOMA | `soma` | Fastest start for supported sandbox images, offered at `small` (2 vCPU / 4 GiB), `medium` (4 / 8 GiB), and `large` (8 / 16 GiB), with live vCPU and memory resize up and down. |
| Auto | `auto` | Let the platform pick the best runtime for the request. |

`runtime` is the name the SDKs and the CLI use; the REST field is `runtime_profile`. The mapping is `firecracker` to `standard`, `soma` to `soma`, and `auto` to `auto`.
Omitting the field is treated exactly as `standard`. A value outside those three is refused with `422 INVALID_SANDBOX_RUNTIME_PROFILE`, and the error names the allowed set.

## List the runtimes your organization offers

`GET /api/v1/sandboxes/runtimes` reports the runtimes available to your organization and what each runtime reports it supports today.

```http
GET /api/v1/sandboxes/runtimes
Authorization: Bearer msk_u_...
```

```json

      "default": true,

      "unavailable_reason": null,
      "capabilities": {
        "browser": true,

        "persistence": true,
        "pause": true,
        "gpu": false,
        "max_shape": { "cpu_count": 16, "memory_mb": 32768, "disk_size_mb": 163840 }
      }
    },
    {
      "id": "soma",
      "runtime_profile": "soma",
      "label": "SOMA",
      "description": "Fastest start for supported sandbox images.",
      "default": false,
      "available": false,
      "unavailable_reason": "GLOBAL_GATE_CLOSED",
      "capabilities": {
        "browser": false,
        "network_egress": false,
        "persistence": false,
        "pause": true,
        "gpu": false,
        "max_shape": { "cpu_count": 8, "memory_mb": 16384, "disk_size_mb": 40960 }
      }
    },
    {
      "id": "auto",
      "runtime_profile": "auto",
      "label": "Auto",
      "description": "Let the platform pick the best runtime for the request.",
      "default": false,
      "available": true,
      "unavailable_reason": null,
      "capabilities": {
        "browser": true,
        "network_egress": true,
        "docker": true,
        "persistence": true,
        "pause": true,
        "gpu": false,
        "max_shape": { "cpu_count": 16, "memory_mb": 32768, "disk_size_mb": 163840 }
      }
    }
  ]
}
```

Read `available` before you offer a runtime. When it is `false`, `unavailable_reason` says why:

- `GLOBAL_GATE_CLOSED` - the platform has not enabled SOMA for customer traffic yet.
- `ORG_RESTRICTED` - SOMA is turned off for your organization by policy.
- `NOT_CONFIGURED` - SOMA is switched on but has no default capacity configured yet.

The `capabilities` flags state what a runtime does today. They come from this endpoint, so read the entry for the runtime you plan to use instead of inferring a capability from its name.

## Choose a runtime on create

```bash
# List the runtimes your organization can select
curl https://api.miosa.ai/api/v1/sandboxes/runtimes \
  -H "Authorization: Bearer $MIOSA_API_KEY"

# Create a SOMA sandbox
curl -X POST https://api.miosa.ai/api/v1/sandboxes \
  -H "Authorization: Bearer $MIOSA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "runtime_profile": "soma", "size": "small", "template_id": "miosa-sandbox" }'
```

```typescript

const miosa = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

const runtimes = await miosa.runtimes.list();
const sandbox = await miosa.sandboxes.create({ runtime: "soma", size: "small" });
```

```python

from miosa import Miosa

client = Miosa(api_key=os.environ["MIOSA_API_KEY"])

runtimes = client.runtimes.list()
sandbox = client.sandboxes.create(runtime="soma", size="small")
```

```bash
miosa runtimes list
miosa create --runtime soma --size small
```

`miosa runtimes list` prints each runtime with its availability and reason, so you can see whether SOMA is offered to your organization before selecting it.

If a runtime cannot serve the requested shape, create is refused with `422 SOMA_RUNTIME_UNSUPPORTED_REQUEST`, naming the runtime's maximum shape, before any machine is admitted.
A sandbox response carries `runtime`: `"firecracker"` or `"soma"`, the engine it actually runs on, so an `auto` request that fell back reports `"firecracker"`.

## What happens when you ask for SOMA

`soma` and `auto` are checked against a trusted runtime policy for your organization before any host work starts.
If the request cannot be honoured, create fails closed with a typed error rather than silently running on the other engine. There is never a silent fallback.

Once your organization is enabled, a SOMA create needs two things to succeed:

1. **An enabled runtime policy** for your organization that carries the SOMA requirements.
2. **Qualified capacity.** A host profile that is approved, has a fresh host-truth observation, and holds a certified Generation for the requested shape.

### Select it

Create sandboxes with `runtime_profile: "soma"`, or `"auto"` to let the platform choose.
Read `available` from `GET /api/v1/sandboxes/runtimes` first; when it is `false`, `unavailable_reason` says why, and a shape with no certified Generation for your request is refused before any machine is admitted.

Do not confuse this with the **SOMA one-hop runner**, which the SDKs expose through `config.runner.enabled` (or the `MIOSA_RUNNER_MODE=1` environment variable).
That option is a transport fast path, not a runtime selector: it sends `create`, `exec`, and `destroy` straight to the runner fleet instead of through the control plane first. It says nothing about whether the sandbox runs on SOMA or Firecracker, and every other client path is unaffected either way.
The [Sizing and limits](/docs/develop/sandboxes/sizing/) page documents that runner path in full, including its request shape and its `Soma-Runner-Url` header.

## Feature parity and gaps

Pick SOMA for a workload once you have confirmed it does not depend on a gap below.

What is the same on both engines:

- The sandbox API contract, response shapes, and error codes.
- Named resource contracts. SOMA serves `small`, `medium`, and `large`; Firecracker serves every size, `xs` through `xl`.
- `exec`, streaming output, and the file API: read, write, list, mkdir, and remove.
- Create, extend, and destroy. Pause, persistence, snapshots, and fork are Firecracker only for now.
- Pricing and billing, which accrue per second at the price of the size regardless of engine.

What to confirm before you switch:

- **No live browser viewer yet.** A SOMA sandbox ships Docker and Chromium, but not the virtual display the live viewer renders, so the live viewer is not available on SOMA yet.
- **No pause, snapshot, or fork yet.** A SOMA sandbox cannot be paused, snapshotted, or forked.
  These arrive in their own release.
- **Long commands on SOMA.** The executable and each argument are limited to 4096 bytes, and a longer shell command fails today with a `502 AGENT_UNAVAILABLE` that looks retryable.
  Send it as a file, or on standard input, instead.
<!-- TODO(team-lead, before deploy): the SOMA persistence behavior below (default `persistent: false`, and a `422` when `persistent: true` is sent with SOMA) lands with #1993. Confirm #1993 is deployed before this branch ships. -->
- **SOMA sandboxes are not persistent yet.** State does not survive a stop or a timeout, so a SOMA create defaults to `persistent: false`, and `persistent: true` with SOMA is refused with a `422`. A disposable SOMA sandbox whose timeout expires is deleted. Keep durable state in a data service, or use Firecracker when you need a persistent sandbox.
- **Only sandboxes take a runtime.** There is no runtime choice for desktop Computers, which run on Firecracker.
- **Check the capability flags.** Read the runtime's `capabilities` from `GET /api/v1/sandboxes/runtimes` and confirm the features your workload needs are enabled before you switch.
- **The shape ceiling is real.** A request above a runtime's `max_shape` is refused with `422 SOMA_RUNTIME_UNSUPPORTED_REQUEST`, so stay within the advertised shape.
- **SOMA capacity is limited.** A SOMA create needs a certified Generation for the exact shape you asked for, on a host that is approved and freshly observed.
- **SOMA is alpha software.** Its own repository labels the engine `1.0.0-alpha.1` and keeps a claim ledger of what is proven and what is still only designed.

# Support

URL: https://miosa.ai/docs/support
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/support
Source: src/routes/docs/support/+page.md
Description: How to reach the MIOSA team, what to include so a ticket resolves fast, and where to check status and what has shipped.

# Support

## Get in touch

- **In-product ticket.** Open a support ticket from the MIOSA dashboard. This is the fastest path for account-specific issues because it carries your tenant context.
- **Email.** Write to `platform@miosa.ai` for anything that is not tied to a live resource, such as roadmap questions or a limitation you need lifted.

## What to include

A precise report resolves in one round trip. Include:

- The **resource id** (sandbox, computer, deployment, secret) and your tenant or workspace.
- The **operation** that failed and how you invoked it (SDK call, CLI command, raw request).
- A **timestamp with timezone**, and the request's **`x-request-id`** header if you have it.
- The **error text** exactly as it came back, including the status code.
- What you already checked, such as the pending network queue or build logs.

Remove API keys, tokens, host keys, private URLs that contain tokens, and any sensitive command output. Never paste a live `msk_*` key or a secret value into a ticket.

## Before you open a ticket

Many issues have a documented fix:

- [Troubleshooting](/docs/troubleshooting/) is the front door for sandbox, exec, preview, network, and deploy problems.
- [Security troubleshooting](/docs/security/troubleshooting/) covers secrets, OAuth, the network allowlist, and the audit log.
- `miosa doctor` checks your CLI version, config, endpoint, key, and clock skew in one command.

## Status and changes

- **Status page.** The status page shows current platform health and recent incidents. Check it first if something looks broadly broken rather than scoped to your tenant.
- **Changelog.** The [changelog](/docs/changelog/) lists what shipped, and [Known limitations](/docs/known-limitations/) lists what has not.

## Raising a limit

Concurrency, rate limits, and volume terms can be raised for a plan. Ask through the same channels and include your expected scale; see [Pricing and limits](/docs/pricing/) for the current defaults.

# Troubleshooting

Fallback URL: https://miosa.roberto-c49.workers.dev/docs/troubleshooting
Source: src/routes/docs/troubleshooting/+page.md
Description: The front door for things that are not working: sandbox, exec, preview, secret, network, and deploy failures, and where to look for each.

# Troubleshooting

Start with the exact resource id and the operation that failed. Most requests also return an `x-request-id` header  -  include it in any support request.

```bash
miosa doctor   # checks CLI version, config, endpoint, key, and clock skew
```

A skewed clock breaks signed webhooks and expiring tokens, so `miosa doctor` is a fast first check.

## Sandbox will not start

- **Still `provisioning`.** The runtime is not ready yet. Poll `GET /api/v1/sandboxes/{id}` and wait for `state` to become `running` and `ready` to be `true`.
- **`error`.** A boot or runtime failure. Check `sbx.data["metadata"]` for `last_error`, then destroy and create a new sandbox.
- **`exec` is refused.** A sandbox that is still starting rejects commands. The CLI's `exec` retries with backoff for up to 90 seconds; SDK callers should do the same or wait for `ready`.

## Commands fail or hang

- **A command returns non-zero.** The sandbox exits with the remote command's status. Read `stderr`; nothing is silently swallowed.
- **`exec` times out.** The sandbox `exec` endpoint accepts a `timeout` of 1 to 86,400 seconds (default 3,600) regardless of the sandbox's own timeout. For long work, start a [background process](/docs/develop/sandboxes/long-running-tasks/) and poll its logs instead.
- **A file upload fails.** The maximum file upload is 500 MB. Split larger artifacts or write them from inside the sandbox.
- **HTTP `429`.** You hit a rate limit. Wait for the seconds in the `Retry-After` header. See [Rate limits](/docs/rate-limits/).

## Previews do not load

- **`404` or connection refused.** Nothing is listening on the port you exposed. Confirm the server is bound to `0.0.0.0`, not just `127.0.0.1`, and that the port number matches.
- **A private preview needs a token.** Private previews require a valid token. See [Previews](/docs/develop/previews/) for visibility and sharing.

## A secret is not working

Secrets are covered in depth in [Security troubleshooting](/docs/security/troubleshooting/). That page catalogs the most common issues  -  a placeholder that is not swapped, an unbound or mismatched scope, and rotation that seems not to take effect  -  with root causes and fixes, alongside Connect Accounts, the Network Allowlist, the Audit Log, and white-label credentials.

## The network is blocked

A sandbox starts in audit-only mode, so nothing is blocked until you enforce an allowlist. If a call is blocked, check the pending queue (`sandbox.network.pending()`) or filter the audit log by `action=reject`; each row names the rule in `rejected_by`. Common gaps (`pip`, `npm`, CDNs) are listed in [Internet access and egress](/docs/develop/sandboxes/internet-access/).

## A deployment failed

- **Build fails.** Read the build logs for the deployment version; see the [Docker Host deploy guide](/docs/docker-host/docker-deploy/) for container build paths.
- **A custom domain does not resolve.** Apex records need ALIAS / ANAME support in your DNS provider.
- **You need the previous version back.** Roll back to a prior release; see [Releases](/docs/docker-host/releases/) and [Rollback](/docs/docker-host/rollback/).

For host, tunnel, and bring-your-own-cloud problems, see [OpenComputers troubleshooting](/docs/opencomputers/troubleshooting/).

## SSH and connections

There is no public SSH endpoint. `miosa ssh`, the SDK SSH tunnel, and preview URLs are the only ways in. See [Connecting to a running sandbox](/docs/develop/sandboxes/connect/).

## Still stuck

Open a support ticket from the MIOSA dashboard and include the resource id, the operation, a timestamp with timezone, and the `x-request-id`. Remove API keys, tokens, and private URLs from anything you paste. See [Support](/docs/support/) for other channels.

Source: src/routes/docs/ui-components/+page.md
Description: Drop-in React, Vue, and Svelte components for embedding MIOSA sandboxes in your own frontend.

# UI Components

`@miosa/react`, `@miosa/vue`, and `@miosa/svelte` are drop-in component libraries that let you embed live MIOSA sandboxes directly in your own frontend  -  no iframe glue code, no WebSocket wiring, no API plumbing.

Each package ships four production-ready components:

| Component | What it renders |
|---|---|
| `` | A sandboxed iframe showing your sandbox's HTTP preview URL |
| `` | A full xterm.js terminal connected to a sandbox PTY over WebSocket |
| `` | An interactive file browser backed by the sandbox filesystem |
| `` | A usage summary widget (compute seconds, storage, egress) per end-user |

These are the customer-facing drop-in packages: your app imports them to embed a sandbox in your own frontend. They are separate from the MIOSA Foundation component library, which is the internal UI system for building the MIOSA product itself. Use [Foundation Component Library](/docs/component-library) for the product UI system, design tokens, cleanup rules, and reusable internal components.

## Auth model

Your MIOSA API key (`msk_*`) must stay on your server. Components that accept an `apiKey` prop are intended for **server-rendered** or **trusted-client** contexts only. For public-facing embeds, generate a short-lived preview token on your backend and pass it as `previewToken`.

The recommended pattern for public embeds:

Diagram:
sequenceDiagram
    participant Browser
    participant YourBackend
    participant MiosaAPI as api.miosa.ai

    Browser->>YourBackend: GET /sandbox-token?sandboxId=sb_...
    YourBackend->>MiosaAPI: POST /api/v1/sandboxes/{id}/preview-token
    Note over YourBackend,MiosaAPI: Uses msk_* API key  -  server only
    MiosaAPI-->>YourBackend: { token, expires_at }
    YourBackend-->>Browser: { token }
    Browser->>Browser:

`` and `` both accept a `previewToken` in place of an `apiKey`. Tokens are short-lived (1 hour by default) and scoped to a single sandbox.

## Which framework package to choose

| If you use... | Install |
|---|---|
| React / Next.js / Remix | `@miosa/react` |
| Vue 3 / Nuxt 3 | `@miosa/vue` |
| Svelte 5 / SvelteKit | `@miosa/svelte` |

The component APIs are structurally identical across all three packages. Prop names, event names, and behavior are the same  -  only the import path and framework idioms differ.

## Install

```bash
npm install @miosa/react
# xterm peer deps  -  required only if you use MiosaTerminal
npm install @xterm/xterm @xterm/addon-fit
```

```bash
npm install @miosa/vue
# xterm peer deps  -  required only if you use MiosaTerminal
npm install @xterm/xterm xterm-addon-fit
```

```bash
npm install @miosa/svelte
# xterm peer deps  -  required only if you use MiosaTerminal
npm install @xterm/xterm xterm-addon-fit
```

Also add the stylesheet to your app entry point (React only  -  Vue and Svelte bundle their own scoped styles):

```ts

```

# Foundation UI

URL: https://miosa.ai/docs/ui-components/foundation
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/ui-components/foundation
Source: src/routes/docs/ui-components/foundation/+page.md
Description: The owned MIOSA frontend primitives used by the platform application.

The MIOSA platform owns a Foundation UI primitive set exposed to the Svelte app through the `$foundation` alias.

Use this surface for platform screens before adding route-local buttons, inputs, cards, modals, tabs, tables, or page chrome.

## Owned primitive surface

| Primitive group | Components |
|---|---|
| Actions | `Button`, `PillButton` |
| Forms | `Input`, `RoundedInput`, `Textarea`, `Select`, `Checkbox`, `Toggle`, `RadioGroup`, `Slider` |
| Layout | `GlassCard`, `AppCard`, `Separator`, `ScrollArea`, `Breadcrumb` |
| Feedback | `Alert`, `Toast`, `Loading`, `Skeleton`, `Progress` |
| Overlays | `Modal`, `Popover`, `Tooltip`, `Menu` |
| Data display | `Table`, `Tabs`, `Accordion`, `Avatar` |

## Import path

```svelte

```

The alias is configured in the platform Svelte config and resolves to:

```text
src/lib/foundations-components/src/lib/ui
```

## Compute workspace audit

The Compute workspace was using this surface inconsistently. Shared Compute components often use `$foundation`, but several top-level Compute routes still hand-roll controls, tables, cards, and page shells with route-local CSS.

| Route | Current state |
|---|---|
| Projects | Mostly shared Compute components; low direct Foundation usage in the page. |
| Deploy | High custom UI; raw filters, buttons, selects, table, and route CSS remain. |
| Logs | Partial Foundation usage through `PillButton`; raw inputs and table remain. |
| Analytics | Visible cards and actions converted to `GlassCard` and `PillButton`. |
| Environment Variables | Partial Foundation usage through `PillButton`; raw modal, form, and table remain. |
| Domains | Partial Foundation usage through `PillButton`; raw modal and table remain. |
| Storage | High custom UI; raw tabs, search, buttons, card grid, and route CSS remain. |
| Databases | Partial Foundation usage through `PillButton`; raw cards and modal remain. |
| Sandboxes | Partial Foundation usage through `PillButton`; raw table and filter controls remain. |
| Computers | Partial Foundation usage through `PillButton`; raw table and filter controls remain. |

## Cleanup order

1. Convert route-level actions and empty/error states to `PillButton`, `Alert`, `Skeleton`, and shared empty-state components.
2. Replace raw form controls with `RoundedInput`, `Input`, `Select`, `Checkbox`, and `Toggle`.
3. Replace hand-rolled tabs and chips with `Tabs` or a shared Compute filter-chip component.
4. Replace raw tables and cards with Foundation table primitives or shared Compute table/card components.
5. Collapse repeated shell CSS into shared Compute layout primitives instead of copying page, console, and main CSS per route.

## Verification guardrail

Every migrated route should keep passing:

```bash
pnpm check
pnpm test:e2e tests/platform-shell-regression.spec.ts --project=chromium
pnpm build
```

# React UI Components

URL: https://miosa.ai/docs/ui-components/react
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/ui-components/react
Source: src/routes/docs/ui-components/react/+page.md
Description: Drop-in React components for embedding MIOSA sandboxes  -  MiosaPreview, MiosaTerminal, MiosaFileTree, MiosaUsage.

`@miosa/react` v0.3.2 provides four React components for embedding MIOSA sandboxes in any React application.

## Install

```bash
npm install @miosa/react
# xterm peer deps  -  required only if you use MiosaTerminal
npm install @xterm/xterm @xterm/addon-fit
```

Add the bundled stylesheet to your app entry point:

```ts

```

## MiosaThemeProvider

Wrap your component tree with `MiosaThemeProvider` to set a default theme for all nested Miosa components.

```tsx

export default function App() {
  return (

      {/* all Miosa components inherit theme="dark" */}

  );
}
```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `theme` | `"dark" \| "light"` | `"dark"` | Visual theme applied to all child components |
| `injectStyles` | `boolean` | `false` | When `true`, lazily injects the stylesheet via a `<link>` tag. Prefer the explicit `import '@miosa/react/styles.css'` instead. |
| `children` | `React.ReactNode` |  -  | Required. Your component tree. |

---

## MiosaPreview

Renders a sandboxed `<iframe>` showing the HTTP preview URL for a running sandbox.

```tsx

// Using a short-lived preview token (recommended for public-facing embeds)

// Using an API key (server-rendered / trusted context only)

```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `sandboxId` | `string` |  -  | **Required.** The sandbox ID to preview. |
| `previewToken` | `string` |  -  | Short-lived preview token minted by your backend. Mutually exclusive with `apiKey`. |
| `apiKey` | `string` |  -  | Your MIOSA API key. Mutually exclusive with `previewToken`. Do not expose in the browser. |
| `theme` | `"dark" \| "light"` | `"dark"` | Visual theme. |
| `className` | `string` |  -  | CSS class forwarded to the root element. |
| `onError` | `(err: Error) => void` |  -  | Called when the preview URL cannot be resolved. |

Exactly one of `previewToken` or `apiKey` must be provided.

### States

The component progresses through `idle → loading → ready` (or `error`). A skeleton placeholder is shown while loading. On error, an accessible `role="alert"` message is rendered.

---

## MiosaTerminal

Renders a full PTY terminal connected to a sandbox over WebSocket, powered by xterm.js. The terminal auto-fits to its container and reconnects on resize.

`MiosaTerminal` requires `apiKey`  -  it does not support `previewToken`. Keep this component in server-rendered or internal tooling contexts.

```tsx

 console.log('resized to', cols, rows)}
  onError={(err) => console.error(err)}
/>
```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `sandboxId` | `string` |  -  | **Required.** The sandbox to connect to. |
| `apiKey` | `string` |  -  | **Required.** Your MIOSA API key. |
| `theme` | `"dark" \| "light"` | `"dark"` | Sets the xterm.js color theme. |
| `className` | `string` |  -  | CSS class forwarded to the root `<div>`. |
| `onResize` | `(cols: number, rows: number) => void` |  -  | Called whenever the terminal dimensions change. |
| `onError` | `(err: Error) => void` |  -  | Called on WebSocket errors or if xterm fails to load. |

### Peer dependencies

`@xterm/xterm` and `@xterm/addon-fit` are loaded dynamically at runtime (lazy import), so they will not bloat your initial bundle. The component falls back to the legacy `xterm` package name if `@xterm/xterm` is unavailable.

---

## MiosaFileTree

Renders an interactive file browser backed by the sandbox filesystem. Directories expand and collapse; clicking a file fires `onSelect`. The tree subscribes to filesystem change events and refreshes automatically.

```tsx

 openFile(file.path)}
  onChange={(tree: FileNode[]) => console.log('tree updated', tree)}
/>
```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `sandboxId` | `string` |  -  | **Required.** |
| `apiKey` | `string` |  -  | **Required.** |
| `theme` | `"dark" \| "light"` | `"dark"` | Visual theme. |
| `className` | `string` |  -  | CSS class on the root `<nav>`. |
| `showHidden` | `boolean` | `false` | When `true`, dotfiles and hidden directories are included. |
| `defaultExpanded` | `string[]` | `[]` | Array of directory paths to start expanded, e.g. `['/workspace/src']`. |
| `onSelect` | `(file: FileNode) => void` |  -  | Called when a file (not a directory) is clicked. |
| `onChange` | `(tree: FileNode[]) => void` |  -  | Called after each tree refresh with the full updated tree. |
| `onError` | `(err: Error) => void` |  -  | Called on load or watch errors. |

### FileNode type

```ts
interface FileNode {
  path: string;       // absolute path, e.g. "/workspace/src/index.ts"
  name: string;       // filename segment, e.g. "index.ts"
  type: 'file' | 'directory';
  children?: FileNode[]; // present for directories
}
```

---

## MiosaUsage

Renders a usage summary for a specific end-user  -  compute seconds, aggregated over a time period. Intended for billing dashboards in white-label products.

```tsx

```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `externalUserId` | `string` |  -  | **Required.** Your platform's user ID (the `external_user_id` used when creating sandboxes). |
| `apiKey` | `string` |  -  | **Required.** |
| `period` | `"7d" \| "30d" \| "90d"` | `"30d"` | Time window for usage aggregation. |
| `theme` | `"dark" \| "light"` | `"dark"` | Visual theme. |
| `className` | `string` |  -  | CSS class on the root element. |
| `onError` | `(err: Error) => void` |  -  | Called on fetch errors. |

The component renders a total usage count and a bar chart of daily buckets.

---

## Theming and styling

All components attach BEM class names to their root element for CSS targeting:

| Component | Root class |
|---|---|
| `MiosaPreview` | `.miosa-preview` |
| `MiosaTerminal` | `.miosa-terminal` |
| `MiosaFileTree` | `.miosa-file-tree` |
| `MiosaUsage` | `.miosa-usage` |

Theme variants are appended as modifier classes: `.miosa-preview--dark`, `.miosa-preview--light`, etc.

The `data-miosa-theme` attribute is also set on the root element, allowing CSS attribute selectors:

```css
[data-miosa-theme="dark"] .miosa-preview__frame {
  border: 1px solid #333;
}
```

---

## End-to-end example: Next.js

This example creates a sandbox on page load, then shows the preview, terminal, and file tree side by side.

**`app/api/sandbox-token/route.ts`**  -  backend token endpoint (never expose your API key to the client)

```ts

const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });

export async function POST(req: Request) {
  const { sandboxId } = await req.json() as { sandboxId: string };
  const sandbox = await client.sandboxes.get(sandboxId);
  // @ts-expect-error - previewToken is available on the sandbox object
  const { token } = await sandbox.previewToken(3600);
  return NextResponse.json({ token });
}
```

**`app/workbench/page.tsx`**  -  client component

```tsx
'use client';

  MiosaPreview,
  MiosaTerminal,
  MiosaFileTree,
  MiosaThemeProvider,
} from '@miosa/react';

const SANDBOX_ID = 'sb_abc123'; // created elsewhere in your app

export default function WorkbenchPage() {
  const [token, setToken] = useState<string | null>(null);
  const [selectedFile, setSelectedFile] = useState<string | null>(null);

  useEffect(() => {
    fetch('/api/sandbox-token', {
      method: 'POST',
      headers: { 'Content-Type': 'application/json' },
      body: JSON.stringify({ sandboxId: SANDBOX_ID }),
    })
      .then((r) => r.json() as Promise<{ token: string }>)
      .then(({ token }) => setToken(token));
  }, []);

  if (!token) return <div>Loading workspace…</div>;

  return (

      <div style={{ display: 'grid', gridTemplateColumns: '240px 1fr 1fr', height: '100vh' }}>
        {/* File tree sidebar */}
         setSelectedFile(file.path)}
        />

        {/* Preview panel */}
        <div style={{ display: 'flex', flexDirection: 'column', height: '100%' }}>
          {selectedFile && (
            <div style={{ padding: '8px', fontSize: 12, color: '#888' }}>
              {selectedFile}
            </div>
          )}

        </div>

        {/* Terminal panel */}
         console.error('[terminal]', err)}
        />
      </div>

  );
}
```

In production, generate the preview token on your Next.js server side (e.g. a Server Component or API route) rather than in a `useEffect`. This keeps your API key entirely off the client.

# Svelte UI Components

URL: https://miosa.ai/docs/ui-components/svelte
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/ui-components/svelte
Source: src/routes/docs/ui-components/svelte/+page.md
Description: Drop-in Svelte 5 components for embedding MIOSA sandboxes  -  MiosaPreview, MiosaTerminal, MiosaFileTree, MiosaUsage.

`@miosa/svelte` v0.3.2 provides four Svelte 5 components for embedding MIOSA sandboxes. All components use Svelte 5 runes (`$props`, `$state`, `$derived`, `$effect`) and work with SvelteKit out of the box.

## Install

```bash
npm install @miosa/svelte
# xterm peer deps  -  required only if you use MiosaTerminal
npm install @xterm/xterm xterm-addon-fit
```

Styles are scoped inside each `.svelte` file  -  no global stylesheet import required.

## MiosaPreview

Renders a sandboxed `<iframe>` showing the HTTP preview URL for a running sandbox.

```svelte

 console.error(e.detail)}
/>
```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `sandboxId` | `string` |  -  | **Required.** The sandbox ID to preview. |
| `previewToken` | `string` |  -  | Short-lived preview token from your backend. Mutually exclusive with `apiKey`. |
| `apiKey` | `string` |  -  | Your MIOSA API key. Use only in `+page.server.svelte` or trusted SSR contexts. |
| `theme` | `"light" \| "dark"` | `"light"` | Visual theme. |
| `class` | `string` | `""` | CSS class forwarded to the root `<div>`. |

### Events

| Event | Detail | Description |
|---|---|---|
| `error` | `Error` | Dispatched when the preview URL cannot be resolved. |

Exactly one of `previewToken` or `apiKey` must be provided.

The component re-resolves the URL reactively whenever `sandboxId` changes (via `$effect`).

---

## MiosaTerminal

Renders a full PTY terminal connected to a sandbox over WebSocket, powered by xterm.js.

`MiosaTerminal` requires `apiKey`. Place it inside a `+page.server.svelte` data load or pass the key via a server-only environment variable  -  do not embed your API key in client-side markup.

```svelte

 console.log(e.detail.cols, e.detail.rows)}
  on:error={(e) => console.error(e.detail)}
  style="height: 400px"
/>
```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `sandboxId` | `string` |  -  | **Required.** |
| `apiKey` | `string` |  -  | **Required.** |
| `theme` | `"light" \| "dark"` | `"dark"` | Sets the xterm.js color scheme. |

### Events

| Event | Detail | Description |
|---|---|---|
| `resize` | `{ cols: number; rows: number }` | Dispatched when the terminal dimensions change. |
| `error` | `Error` | Dispatched on WebSocket errors or xterm load failure. |

The component auto-fits to its container via `ResizeObserver` and syncs resize events to the PTY. Cleanup (WebSocket close + terminal dispose) runs in `onDestroy`.

---

## MiosaFileTree

Renders a flat-list file browser backed by the sandbox filesystem. Directories expand inline on click; files dispatch a `select` event with the file path.

```svelte

 (selectedPath = e.detail)}
  on:change={(e) => console.log(e.detail.path, e.detail.type)}
/>
```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `sandboxId` | `string` |  -  | **Required.** |
| `apiKey` | `string` |  -  | **Required.** |
| `showHidden` | `boolean` | `false` | Include dotfiles and hidden directories. |
| `defaultExpanded` | `boolean` | `false` | When `true`, all directories start expanded. |

### Events

| Event | Detail | Description |
|---|---|---|
| `select` | `string` | Absolute path of the clicked file, e.g. `/workspace/src/index.ts`. |
| `change` | `{ path: string; type: "created" \| "deleted" \| "modified" }` | Dispatched on filesystem changes. |

The tree uses `$derived` to recompute the flat render list whenever a directory is toggled  -  no recursive component needed.

---

## MiosaUsage

Renders a three-column usage summary (compute seconds, storage GB·hours, egress GB) for a specific end-user.

```svelte

```

### Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `externalUserId` | `string` |  -  | **Required.** Your platform's user ID, matching the `external_user_id` used when creating sandboxes. |
| `apiKey` | `string` |  -  | **Required.** |
| `period` | `"current" \| "last_30" \| "last_7"` | `"current"` | Billing period. `"current"` is the active billing cycle; `"last_30"` / `"last_7"` are rolling windows. |
| `theme` | `"light" \| "dark"` | `"light"` | Visual theme. |

Reactively reloads whenever `externalUserId` or `period` changes via `$effect`. No events are dispatched.

---

## createMiosaClient store

The package also exports a `createMiosaClient` helper for creating a shared client store:

```ts

const client = createMiosaClient({ apiKey: 'msk_...' });
```

This is intended for advanced use cases where you need direct SDK access alongside the components.

---

## End-to-end example: SvelteKit

**`src/routes/workbench/+page.server.ts`**  -  load preview token server-side

```ts

const SANDBOX_ID = 'sb_abc123';

export const load: PageServerLoad = async () => {
  const client = new Miosa({ apiKey: env.MIOSA_API_KEY });
  const sandbox = await client.sandboxes.get(SANDBOX_ID);
  // @ts-expect-error
  const { token } = await sandbox.previewToken(3600);
  return { sandboxId: SANDBOX_ID, previewToken: token };
};
```

**`src/routes/workbench/+page.svelte`**

```svelte

<div class="workbench">
  <aside class="workbench__sidebar">
     (selectedFile = e.detail)}
    />
  </aside>

  <main class="workbench__preview">
    {#if selectedFile}
      <div class="workbench__filepath">{selectedFile}</div>
    {/if}

  </main>

  <section class="workbench__terminal">
     console.error('[terminal]', e.detail)}
    />
  </section>
</div>

<style>
  .workbench {
    display: grid;
    grid-template-columns: 240px 1fr 1fr;
    height: 100vh;
    overflow: hidden;
  }
</style>
```

`$env/dynamic/private` is available only in server-side SvelteKit modules (`+page.server.ts`, hooks, etc.). Never import it in a `+page.svelte` or any other client-side file  -  SvelteKit will throw a build error if you try.

| `change` | `[path: string, type: "created" \| "deleted" \| "modified"]` | Emitted on filesystem changes (when the watch subscription fires). |

---

## MiosaUsage

Renders a three-column usage summary (compute, storage, egress) for a specific end-user.

```vue

<template>

| `theme` | `"light" \| "dark"` | `"light"` | Visual theme. |

Displays `compute_seconds`, `storage_gb_hours`, and `egress_gb`. No events are emitted.

---

## End-to-end example: Nuxt 3

**`server/api/sandbox-token.post.ts`**  -  server route (keeps API key off the client)

```ts

export default defineEventHandler(async (event) => {
  const { sandboxId } = await readBody<{ sandboxId: string }>(event);
  const client = new Miosa({ apiKey: process.env.MIOSA_API_KEY! });
  const sandbox = await client.sandboxes.get(sandboxId);

  return { token };
});
```

**`pages/workbench.vue`**

```vue

<template>
  <div class="workbench">
    <aside class="workbench__sidebar">

      />
    </aside>

    <main class="workbench__preview">
      <div v-if="selectedFile" class="workbench__filepath">{{ selectedFile }}</div>

    </main>

    <section class="workbench__terminal">
       console.error('[terminal]', err)"
      />
    </section>
  </div>
</template>

<style scoped>
.workbench {
  display: grid;
  grid-template-columns: 240px 1fr 1fr;
  height: 100vh;
  overflow: hidden;
}
</style>
```

In Nuxt 3, use `runtimeConfig` to expose the API key only on the server side (`runtimeConfig.miosaApiKey`, not `runtimeConfig.public.miosaApiKey`). This prevents it from being serialized into the client bundle.

# What you can build with MIOSA

URL: https://miosa.ai/docs/use-cases
Fallback URL: https://miosa.roberto-c49.workers.dev/docs/use-cases
Source: src/routes/docs/use-cases/+page.md
Description: Concrete product patterns for MIOSA sandboxes, computers, agent runtimes, generated artifacts, previews, and deployments.

# What you can build with MIOSA

MIOSA is the infrastructure underneath AI products. Your product, or your agent, gets real machines and real URLs:

- **Sandboxes** for code, files, builds, and previews.
- **Computers** for browsers and full desktops, with human handoff.
- **Agents** you dispatch, stream, and collect artifacts from.
- **Deployments and Docker Host** for immutable releases on stable URLs, with custom domains and rollback.
- **Platform features** for white-label products: organizations, workspaces, scoped keys, domains, and usage metering.

```text
User request
  -> agent plans work
  -> sandbox does code, files, builds, tests, artifacts
  -> computer does browser, desktop, screenshots, manual-style tasks
  -> MIOSA streams events and previews
  -> deployment ships the finished app
```

MIOSA is not just a remote shell. It is the execution layer for products that need AI agents to do real work safely.

## Browse the Build gallery

Every product shape below has a step-by-step guide in the [Build gallery](/docs/build/): the primitives you need, an architecture diagram, six steps from API key to custom domain, and a prompt you can hand to your coding agent.

    Org and workspaces
    Branding
    Attribution

    [Start here: Platform builder guide](/docs/platform/overview/)






    Northwind-style agencies that give each client an isolated workspace, build their apps, and hand over domains.

    Multi-tenant
    Quotas
    Custom domains

    [Start here: Platform builder guide](/docs/platform/overview/#northwind-agency-client-work)






    An Acme Corp-style internal platform where your team agents, apps, and data live together on MIOSA.

    Sandbox
    Connectors
    Data

    [Start here: internal Business OS](/docs/build/business-os/)



## Infrastructure and enterprise




    OpenComputers enrolls machines you own so agents can run commands and files on your own hardware.

    OpenComputers
    Hosts
    Meshes

    [Start here: OpenComputers](/docs/opencomputers/)






    Fractal gives enterprise data a governed home, so agents work against your systems with the right controls.

    Fractal
    Data
    Governance

    [Start here: Fractal enterprise data](/docs/data/fractal/)



MIOSA can host the application, data, workflow, customer boundary, and deployment for these products today.
Specialized model and media execution may use connected providers.
Managed GPU execution and customer-cloud placement remain gated until the availability page marks them shipped.
See [Availability and roadmap](/docs/availability/).

## Product primitives

| Primitive | Use it for | Not for |
|---|---|---|
| **Sandbox** | Code, files, commands, package installs, builds, tests, generated artifacts, preview servers | GUI/browser interaction |
| **Computer** | Browser automation, screenshots, mouse/keyboard, desktop apps, visual QA, user handoff | Headless code builds that do not need a desktop |
| **Deployment** | Stable public app/site/API URLs, versions, releases, rollback | Active development iteration |
| **Docker Host** | Many customer apps running as isolated containers on one workspace Docker Host host | Generic sandbox development |
| **Artifacts** | Files created by agents: PDFs, docs, images, reports, exports, screenshots | Hidden temporary state |
| **Events** | Real-time UI updates: tool calls, stdout, file writes, preview readiness, deployment status | Long-term storage |

## Build an agent-company product

Several modern AI products package the same high-level pattern: an agent, a
persistent workspace, connected apps, a browser or cloud device, jobs, files,
and generated deliverables. MIOSA exposes those primitives directly, so you can
build your own version inside your product.

```text
Your product UI
  -> agent configuration
  -> device policy
  -> sandbox/computer/local device
  -> connected accounts and managed connectors
  -> streamed tool calls and events
  -> files, artifacts, previews, jobs, and deployments
```

| Product shape | MIOSA primitives |
|---|---|
| Always-on virtual device | Persistent sandbox or computer, primary device policy, snapshots, jobs |
| Agent team | Orchestrator, child sandboxes, child computers, shared artifacts, event stream |
| Mini-app builder | Next.js sandbox, preview URL, artifact panel, publish flow |
| Operator agent | Browser computer, connected apps, schedules, approvals, memory |
| Design/research agent | Web research, a managed research connector, files, browser screenshots |
| 24/7 monitoring job | Scheduled trigger, persistent device, app connector, notifications |

The important architecture point is that the agent should work in a MIOSA
device. The local CLI, MCP client, or your backend orchestrates, but files,
commands, browser actions, previews, and artifacts live in the assigned runtime.

See [Build an agent-company platform](/docs/guides/build-agent-company/),
[What MIOSA agents can do](/docs/guides/agent-capabilities/),
[Agent devices](/docs/guides/agent-devices/), and
[Agent orchestration](/docs/guides/agent-orchestration/) for the full model.

For AI coding products, the default loop should be sandbox-first: create or
resume a sandbox, write files inside `/workspace`, run commands inside the
sandbox, show the preview, snapshot progress, then publish.

## Example: generated app builder

Diagram:
sequenceDiagram
  participant User
  participant Product as Your product
  participant Agent
  participant S as MIOSA Sandbox
  participant D as MIOSA Deploy

  User->>Product: Build a landing page for my customer
  Product->>Agent: Start build task
  Agent->>S: get_or_create(name, template_id=nextjs)
  Agent->>S: write /workspace/app/page.tsx
  Agent->>S: exec npm install && npm run build
  S-->>Product: stream stdout, stderr, file events
  Agent->>S: start preview on port 3000
  S-->>Product: preview_url
  User->>Product: Make the hero more premium
  Agent->>S: patch files and rerun checks
  User->>Product: Ship it
  Agent->>D: publish /workspace
  D-->>Product: public_url

Your frontend can show the same work stream users expect from modern AI
builders: tool calls, command output, generated files, preview links, screenshots,
and final deployment URLs.

---

## Example: artifact workspace

Use a sandbox when the output is a file, not a deployed app.

```text
User asks for a proposal
  -> agent writes Python or Node generator
  -> sandbox creates proposal.html
  -> sandbox renders proposal.pdf
  -> sandbox creates proposal.docx
  -> product shows artifacts in a side panel
  -> user downloads or asks for edits
```

Good artifact outputs:

- client proposals
- pitch decks
- data reports
- PDF invoices
- SVG diagrams
- PNG charts
- HTML previews
- ZIP bundles
- code archives

---

## Two sandbox choices, and both cover the jobs

| Choice | Intended job |
|---|---|
| The default sandbox (`miosa-sandbox`) | Everything in one place: Python and Node execution, generated web apps, reports and artifacts, browser testing, and database-backed apps. |
| The desktop (`miosa-desktop`) | GUI work and human takeover, when a person needs to see and drive the screen. |

The product shape stays the same: start the default sandbox, let the agent work inside it.

---

## What to show users in your product

Users should not have to understand VM internals. Show them useful work:

- current task and plan
- tool calls
- command output
- files created or edited
- artifacts generated
- preview URL
- screenshots from browser checks
- deployment URL
- rollback/version history
- credits and runtime usage

The message should be: "Your agent is working in a real cloud workspace. You can
watch it, inspect the files, preview the result, and ship when ready."
