HTTP API

Interactive API docs (served by a running Athenaeum instance): /docs. Machine-readable: GET /api/openapi.json (OpenAPI 3) and GET /api/docs (JSON). Key management is under Settings -> API.

Mutating browser requests require the X-CSRF-Token header (not needed for Basic Auth or API keys). Auth when users exist: session cookie, HTTP Basic, or API key (Authorization: Bearer ath_<token> or X-API-Key: ath_<token>).
