Swagger UI

Interactive browser for openapi.json, generated from the canonical contract registry by scripts/gen_api_docs.py (see the API reference for the same facts as Markdown). Rendered with a locally vendored Swagger UI (docs/assets/swagger-ui/, Apache-2.0, see its NOTICE.md) — no CDN, no external network request.

Every request/response body here is shown as its JSON-Schema-equivalent shape; the real wire encoding is MessagePack, not JSON — see openapi.json's own info.description.
