Introspect a token
RFC 7662 token introspection: the calling client authenticates (client_id, plus client_secret for confidential clients) and submits a token to check, as form or JSON. Returns active true only for a token that the authenticated client itself issued and that is neither revoked nor expired, along with its scope, client_id, username, token_type, exp, iat, and sub; for any other token (unknown, expired, revoked, or belonging to a different client) it returns active false without leaking details.
