# Start the onboarding agent and get a stream id

> Creates, migrates or integrates a site. **Not mounted in production unless `AGENT_SURFACE=on`.** The agent routes run open-ended loops with file and shell tools, so the surface refuses to mount at all when no credential (`ACCESS_PASSWORD_HASH` or `ORCHESTRATOR_ACCESS_TOKEN`) is configured, and answers 404 when unmounted. In development it mounts but accepts loopback callers only. Spawning the Claude CLI on the host is a further opt-in, `AGENT_CLI=1`, off everywhere by default. See `apps/orchestrator/src/agent-surface.ts`.



## OpenAPI

````yaml /api-reference/orchestrator.openapi.json post /sites-agent/start
openapi: 3.0.3
info:
  title: Avocado Studio Orchestrator API
  description: >-
    HTTP API exposed by the orchestrator. The brain that runs editor sessions,
    calls the LLMs, and serves draft state to integrated sites.


    The route list is the one the standalone Fastify server registers
    (`apps/orchestrator/src`); the handlers behind most of them live in
    `packages/orchestrator-core/src/http`, so library mode —
    `createOrchestrator()` from `@avocadostudio-ai/site-sdk` — serves the same
    shapes from the same code. Where the two differ, the route says so.


    **Note**: most routes carry no Fastify response schema, so responses are
    described in prose rather than typed here. Request shapes are taken from the
    handler source. See [the API Reference index](/api-reference) for context.


    **Auth**: in the standalone server only the agent surface enforces the
    access gate — `/chat` and `/ops` remain open. `createOrchestrator()` gates
    every route instead. Under that gate `GET /auth/status`, `POST
    /auth/verify`, `GET /health` and `GET /generated-images/*` are public — the
    first two are how a caller obtains a credential, a probe that needs one is
    not a probe, and an image tag on the rendered page cannot send a header —
    while every other route wants the token as `x-access-token`, `Authorization:
    Bearer`, or `?accessToken=` on `EventSource`. A refusal is `401` with
    `{"error":"unauthorized"}`. On a `closed` mount — `NODE_ENV=production` with
    no credential configured and no `auth` hook — that body also carries
    `reason`, the sentence naming the variable that would open it; `error` keeps
    its exact value either way, because that is the field the editor matches on
    to re-prompt.
