## OpenAPI

````yaml /openapi/ehr-api.v1.yaml get /v1/clinics/{clinic_id}/inventory/items/{item_id}
openapi: 3.1.0
info:
  title: ClinikEHR API
  version: 1.0.0
  description: >-
    Server-to-server REST API for a clinic's own data, reached with a key the
    clinic (or a developer workspace) creates in the developer portal.


    Authenticate every request with `Authorization: Bearer <key>`. Test keys
    reach only your workspace's own synthetic sandbox; live keys reach the
    clinic that created them. Lists wrap their rows as `{ data, has_more,
    next_cursor }`; single resources are returned directly. Errors are
    `application/problem+json` (RFC 9457) with a stable `code`.


    Write requests accept an `Idempotency-Key` header so a retry never repeats a
    change. See the guides for authentication, permissions, pagination, rate
    limits and retries.
