UC San Diego Shibboleth Identity Provider (InCommon / eduGAIN) is one of 12 APIs that [University of California, San Diego](https://apis.io/providers/ucsd/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, SAML, Shibboleth, InCommon, and eduGAIN. The published artifact set on APIs.io includes API documentation.

UC San Diego's SAML 2.0 identity provider, "TritON", registered in the InCommon Federation under entityID urn:mace:incommon:ucsd.edu and distributed through the InCommon MDQ metadata service. The metadata is complete, public and machine-readable — organization name, validity window, certificates and SingleSignOnService bindings at https://a5.ucsd.edu/tritON/profile/SAML2/{POST,Redirect}/SSO. Institution-operated by definition and, in practice, the only fully open machine-readable contract UC San Diego publishes. It satisfies the education regime's `saml` and `shibboleth` domain standards.
