info:
  title: OpenID Connect Authentication Session API
  description: OpenID Connect (OIDC) is an identity layer built on top of the OAuth 2.0 protocol. It allows clients to verify the identity of end-users based on the authentication performed by an authorization server, and to obtain basic profile information about the end-user in an interoperable and REST-like manner. This specification covers the core OIDC endpoints including discovery, token, userinfo, and JWKS.
