summary:

api_key_in: []
oauth2_flows: [authorizationCode]
note: >-
Two distinct authentication stories sit under one organization. (1) The published
OpenTravel 2.0 Swagger contracts declare NO securityDefinitions at all — authentication is
left entirely to the implementer that hosts the resource. (2) opentravel.org itself runs a
real OAuth 2.1 authorization server in front of its Model Context Protocol endpoints.

No registration_endpoint is advertised; the authorization server sets
client_id_metadata_document_supported=true (client ID metadata documents, the OAuth
client-id-as-URL pattern) instead of RFC 7591 dynamic client registration.

schemes: []
evidence: >-
All eight harvested Swagger 2.0 documents were parsed on 2026-07-28: securityDefinitions is
absent and no operation carries a security requirement. The OTM compiler that generated
them emits the message contract only; 401 and 403 responses are declared on every
operation but no scheme is named to satisfy them.
