  title: API Evangelist enhancements for marginalia public API
  version: 1.0.0
  description: >-
    Non-destructive annotations over the provider's generated OpenAPI 3.0.3 (fetched verbatim from
    https://marginalia.polycode.co.uk/api/openapi.json on 2026-09-19). The original is never mutated; these actions
    add catalog metadata, tags grouped by resource, the X-API-Key security scheme the agent card declares but the
    spec omits, and the observed 401/404 error responses. Generated by API Evangelist (method: generated).

          Declared in the A2A agent card, not in the spec. Optional today; routes a request to the private graph the key
          is bound to. Observed live: GET /api/keys/whoami without it returns 401 {"error":"send the key as X-API-Key"}.
