  title: API Evangelist enhancements — Neurable Pipe Service

  x-source: openapi/neurable-pipe-service-openapi.yml
  x-note: >-
    Captures API Evangelist's enhancements over the verbatim spec Neurable serves at
    https://pipe.neurable.com/openapi.json. The original is never mutated. Everything added below
    is read off the live OpenID Connect discovery document this same service publishes at
    /.well-known/openid-configuration (HTTP 200, 2026-08-04) — nothing is invented.

  description: >-
    Declare the OAuth 2.0 / OIDC schemes this service itself implements. The document describes
    /oauth/authorize, /oauth/token and /oidc/userinfo as ordinary operations but declares no
    securitySchemes, so the fact that this IS an authorization server is invisible to tooling.
  update:
    securitySchemes:
      neurableOIDC:
        type: openIdConnect
        openIdConnectUrl: https://pipe.neurable.com/.well-known/openid-configuration
        description: Read from the live discovery document served by this same host.

        description: >-
          Read from the live discovery document. PKCE (S256) is mandatory — code_challenge and
          code_challenge_method are REQUIRED parameters on /oauth/authorize — and an `audience`
          parameter is also required.
        flows:
          authorizationCode:
            authorizationUrl: https://pipe.neurable.com/oauth/authorize
            tokenUrl: https://pipe.neurable.com/oauth/token

              openid: Standard OpenID Connect scope; request an ID token.

  update:
    security:
    - neurableOIDC: []
    x-inferred-security: >-
      Not declared by Neurable. GET /me returns GetMeResponse for the calling principal, so it
      cannot be anonymous.
