At most 500 turns; narrow with `since`. ## OpenAPI ````yaml https://api.doers.sh/openapi.json get /v2/coach/usage openapi: 3.1.0 info: title: Doers API version: 2.0.0 description: >- The open API of Doers: tasks, projects, areas, prioritised context and the day's plan. ## Authentication Every route requires a bearer token, generated from **Settings > API & MCP** in the app: ``` Authorization: Bearer pc_… ``` ## Two date fields, not to be confused - `when` — the **schedule**: `today`, `anytime` (Later), `someday` (Future) or a date. - `deadline` — the **commitment**, independent of the schedule. ## Time zone The server reasons in UTC and does not know yours. Send the `X-PC-Today: YYYY-MM-DD` header (or the `day` argument where it exists) so dated operations use your local day. ## MCP server The same token gives access to the [Model Context Protocol](https://modelcontextprotocol.io) server at `POST https://doers.sh/mcp`, which exposes the same operations as tools for Claude, Cursor and other compatible clients. servers: - url: https://api.doers.sh description: Production. security: - bearerAuth: [] tags: - name: Tasks - name: Projects - name: Areas - name: Headings - name: Comments - name: Realtime - name: Devices - name: Context - name: Plan - name: Sessions - name: Rounds - name: Journal - name: Habits - name: Stats - name: Users - name: Profiles - name: Workspaces - name: Access - name: Activity - name: Tokens - name: Referrals - name: Files - name: Connections - name: Collaborators - name: Links - name: Packages - name: Installs - name: Billing - name: Calendar - name: Coach - name: Marketplace paths: /v2/coach/usage: get: tags: - Coach summary: What your turns cost description: >- Every call your account made to the model, newest first, with its token counts and its price in nano-dollars under the catalogue version it was recorded with — so a price change never rewrites a past turn.
