TU Berlin Matrix Homeserver (Client-Server API) is one of 8 APIs that [Technical University of Berlin](https://apis.io/providers/tu-berlin/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Messaging, Matrix, Synapse, Campus Life, and Federation. The published artifact set on APIs.io includes API documentation and authentication docs.

TU Berlin runs its own Matrix homeserver for institutional messaging, with an Element web client at chat.tu-berlin.de and documentation at docs.chat.tu-berlin.de. The Client-Server API answers unauthenticated where the specification says it should: /_matrix/client/versions returns 200 advertising r0.0.1 through v1.12, /_matrix/federation/v1/version reports Synapse 1.157.2, /.well-known/matrix/client returns the homeserver base URL and a Jitsi domain at meet.innocampus.tu-berlin.de, and /_matrix/client/v3/login lists m.login.password and m.login.application_service. Guest access is disabled. A genuine campus-life API surface, institution-operated, speaking an open standard.
