  source: >-
    Authored by API Evangelist over the provider's own spec at https://pay.agribus-connect.net/v3/api-docs.
    Every action below either supplies metadata the springdoc-generated document omits, or records
    behaviour observed on live anonymous probes of pay.agribus-connect.net on 2026-09-12. The original
    document is never mutated.
  note: >-
    The base document has a null info object and an http:// server URL. Both are springdoc
    generation defaults rather than statements by the provider, and both break tooling: a null info
    fails OpenAPI validation, and the http server is not the scheme the host actually serves.
actions:
  - target: $.info
    description: >-
      The published document carries info: null. Supply the identity fields, attributed to
      API Evangelist rather than presented as the provider's own.

        Stripe-backed subscription, card, coupon and invoice management plus Google Play purchase verification for the AgriBus paid plans.
        Contract harvested verbatim from https://pay.agribus-connect.net/v3/api-docs; this description is
        supplied by API Evangelist because the published document has no info object.

    description: >-
      The published servers[] entry is http://pay.agribus-connect.net with the springdoc placeholder
      description "Generated server url". The host serves HTTPS only (HTTP/2, TLS observed
      2026-09-12). Record the https origin without removing the provider's own entry.
    update:
      - url: https://pay.agribus-connect.net
        description: >-
          Production origin as observed by API Evangelist. The provider's own document says http.
  - target: $.components.securitySchemes.bearerAuth
    description: Record where the verification key actually lives.
    update:
      description: >-
        RS256 JWT issued by auth.agribus-connect.net. Verify against the JWKS at
        https://auth.agribus-connect.net/.well-known/jwks.json (kid connect-auth-key-1). Note that
        an unauthenticated request is answered with HTTP 403 and no WWW-Authenticate header on the
        auth and datastore services, and with HTTP 500 on the pay service.

    description: >-
      Record, at document level, that no operation in the published contract declares any non-200
      response. The error envelopes below were observed live, not published.
    update:
      x-api-evangelist-error-envelopes:
        observed: true
        source: errors/agriinfodesign-problem-types.yml
        formats:
          - '{"code":"<DOMAIN>-<int>","message":"..."}'
          - '{"timestamp":"<ISO8601>","status":<int>,"error":"<reason>","path":"<path>"}'
        rfc9457: false
      x-api-evangelist-known-defects:
        - >-
          Timestamp properties declare "format": "2016-01-01T00:00:00.000Z" - an example value in
          the format keyword - instead of "date-time".
        - No operation declares a 4xx or 5xx response.
        - No operation declares an operation-level security[] requirement.
