No recent identity check. The key acts for the organisation you have active, is created by you, and appears on the Keys page like any other. Without `scopes` the key gets the CLI default (devices:read, devices:act, devices:lease, runs:start, orders:place) narrowed to what your session holds. Without `ttlMs` it lasts 180 days from when the CLI collects it. The key is minted on the CLI's next poll, not by this call, and that collection does not re-check your membership. An approval near the code's deadline extends it to at least 60 seconds out so the CLI can still collect. Omitting `scopes` when your session holds none of the defaults is refused 403. Hosted deployments only. A local checkout does not mount this route, so calling it there is a 404. ## OpenAPI ````yaml /api/openapi.json post /v1/cli-sessions/{userCode}/approve openapi: 3.1.0 info: title: Phonebase HTTP API version: 0.1.0 summary: >- Every HTTP operation the control plane mounts, generated from the app's own route table. description: >- The control plane exposes two HTTP surfaces, and reading the boundary between them matters more than reading any single endpoint. The CONTROL surface is what your backend and your operators call. It takes a bearer token in the `Authorization` header, and two credential channels resolve to the same authorization context: an OAuth 2.1 access token for interactive clients, or an org scoped API key for headless ones. The DEVICE surface, under `/vrx/{runToken}/v1`, is what a worker calls while executing one run. Its credential is the run token in the url path, and it reads no `Authorization` header at all. Device control itself is not REST. An agent taps, swipes and reads the screen over the Model Context Protocol at `POST /mcp`, one tool call at a time. There is no `POST /v1/devices/{id}/tap`, and if you are looking for one, start with the tool reference instead. Operations marked `"x-phonebase-modes": ["hosted"]` exist only on a hosted deployment; a local checkout does not mount them. servers: - url: '{origin}' description: Your control plane origin. variables: origin: default: https://mcp.phonebase.co enum: - https://mcp.phonebase.co - http://127.0.0.1:8788 description: >- The hosted deployment serves the public origin its metadata document advertises, and that is the default here.

Send `Authorization: Bearer `. Two kinds of token are accepted and they are told apart by shape, not by a separate header. A token beginning `pbk_` is an org scoped API key, whose public half and secret half are generated together and of which only a hash of the secret is ever stored; anything else is treated as an OAuth 2.1 access token and verified against the authorization server's keys. Both resolve to the same context: an org, a principal and a set of scopes. Nothing downstream branches on which channel you used, with one deliberate exception, key management, which requires a signed-in person so that a key can never mint another key. Scopes are enforced when MCP tools are REGISTERED rather than when they are called, so a tool your credential cannot use is absent from `tools/list` rather than refused mid gesture. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
