Instituto Superior Tecnico SAML 2.0 Identity Provider (RCTSaai / eduGAIN) is one of 11 APIs that [University of Lisbon](https://apis.io/providers/university-of-lisbon/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, eduGAIN, RCTSaai, and SIRTFI. The published artifact set on APIs.io includes authentication docs.

The identity provider for Instituto Superior Tecnico, federated through RCTSaai into eduGAIN and asserting SIRTFI incident-response assurance — a stronger security posture than the central IdP declares. Its registered service provider in the same federation is the FenixEdu deployment listed above, which is how the academic API's person-scoped endpoints are authenticated. The entityID is an identifier, not a dereferenceable endpoint: metadata is distributed through the RCTSaai and eduGAIN aggregates.
