Brix Signage Templates API

openapi: 3.2.0
info:
  title: Brix Signage Templates API
  version: '1'
  summary: 'Control plane for Brix digital signage: screens, content, playlists, schedules, casts and emergencies.'
  description: 'Generated from the route table the API actually mounts

    (`apps/api/routes.snapshot.json`), the description each route is required to

    carry (`tests/contracts/route-registry.json`), and request/response schemas

    (`apps/api/src/openapi/`). CI enforces all three, so this document cannot list a

    route that does not exist or omit one that does.


    **Schemas.** 447 operations carry request and response schemas

    (`x-brix-schema: verified`). Each is checked in CI against the response the

    real handler returns — a missing, mistyped or undeclared field fails the build.

    The remaining operations are route-level only (`x-brix-schema: none`): their

    path, method, permission and purpose are exact, but the shape of `data` is not

    yet modelled, and we would rather say so than publish a schema that validates

    against nothing. Objects are open: a new field is not a breaking change.


    **Envelope.** Success bodies are `{ "data": … }`. Failures are

    `{ "error": "", "message": "…" }`, plus `requestId` on a 5xx.

    Many list routes page opt-in (see each operation): pass `?limit=` and

    follow `nextCursor` via `?cursor=` until it is null.


    **Authentication.** `Authorization: Bearer ` with an API key

    (`ak_…`, created in the console under Settings → API & MCP) or a user session. An

    API key carries a creator-chosen set of `resource.verb` permissions and may be

    pinned to one location''s subtree; a key can never be granted a permission its

    creator does not hold. The permission an operation needs is in

    `x-brix-permission` and in its security requirement.


    **Tenancy.** Every request resolves to one workspace. A resource belonging to

    another tenant returns 404, never 403, so a response never confirms that an

    account exists.


    **Rate limits.** A 429 carries `Retry-After`; a 503 `database_busy` means retry

    after the `Retry-After` interval.'
