API Reference
Every public endpoint, grouped by product, with a live playground on each operation.
Each section below documents one product. Open any operation and press Send Request to call it against the environment these docs are served from, the playground targets the same origin, so there is no CORS setup and no proxy.
New here? Getting Started covers base URLs, credentials and rate limits first.
The sections are also machine-readable: everything documented here comes from one OpenAPI
3.0 document, served without authentication from
/openapi-schema/. Point a client generator at
it rather than hand-writing requests.
