It counts the org's unread notifications that need somebody to act, across everything and not just this page, so it does not drop to zero when somebody scrolls. An arrival is not counted: nothing is being asked of anybody. READ STATE IS PER PERSON. A colleague opening the bell does not clear it for you. An API key has no person behind it, so it reads the org's notifications with `readAt` null on all of them, and it cannot mark anything read. One kind is computed rather than stored. An order that has gone past its estimate has no event behind it, only a clock passing a recorded instant, so it appears on the FIRST page with an id prefixed `derived:`. It is marked read like any other item, and it does not repeat on later pages. Hosted deployments only. A local checkout does not mount this route, so calling it there is a 404. ## OpenAPI ````yaml /api/openapi.json get /v1/notifications 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.

Treat it as opaque: its form is not part of this contract. Send it only when you have one, because an empty value is refused rather than read as `no cursor`.

Hosted deployments only. Which budget applied depends on whether this request carried an `Authorization` header, not on which endpoint it was aimed at.

Raised by the rate limiter before any handler runs, which is why its code is not one of the action codes: nothing was attempted, so no action failed. securitySchemes: bearerAuth: type: http scheme: bearer description: >- The control surface credential. 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.
