## OpenAPI

````yaml https://api.doers.sh/openapi.json get /v2/habits/completions
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.
