CWRU Apereo CAS single sign-on (login.case.edu) is one of 9 APIs that [Case Western Reserve University](https://apis.io/providers/case-western-reserve-university/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Single Sign-On, CAS, Apereo, and Identity. The published artifact set on APIs.io includes authentication docs.

CWRU runs an Apereo CAS deployment at login.case.edu as its campus single sign-on service. The CAS 3.0 protocol validation endpoint /cas/p3/serviceValidate answers unauthenticated with a well-formed cas:serviceResponse in the http://www.yale.edu/tp/cas namespace. It is an institution-operated authentication service on the institution's own domain, not a data API: a valid service ticket is required for any substantive response, and there is no public client registration. The CAS OIDC module is deployed but refuses unauthenticated discovery (/cas/oidc/.well-known/openid-configuration returns 401).
