NTU Identity Provider — SGAF / eduGAIN is one of 4 APIs that [Nanyang Technological University](https://apis.io/providers/ntu/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, Shibboleth, and eduGAIN.

NTU's SAML 2.0 identity provider, registered in the Singapore Access Federation (SGAF) by SingAREN and interfederated into eduGAIN, asserting the scope ntu.edu.sg. Live machine-readable SAML metadata with an IDPSSODescriptor and an AttributeAuthorityDescriptor. This is the surface class universities operate that almost never gets catalogued, and it is a genuine institutional fact — but the entityID and endpoints are on SingAREN's federation proxy, not on ntu.edu.sg, so it is recorded as a tenancy rather than as NTU-operated infrastructure.
