DFN-AAI federation membership (eduGAIN) is one of 10 APIs that [Technical University of Darmstadt](https://apis.io/providers/technical-university-of-darmstadt/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Identity Federation, eduGAIN, DFN, SAML, and Metadata. The published artifact set on APIs.io includes API documentation.

TU Darmstadt's identity provider is published in DFN-AAI, the German research-and-education identity federation run by DFN, and is reachable through eduGAIN by extension. Verified live 2026-09-01: the DFN-AAI MDQ service returns the signed EntityDescriptor for https://idp.hrz.tu-darmstadt.de/idp/shibboleth (HTTP 200, 22,505 bytes). A federation is shared by definition; the IdP behind this entry is TU Darmstadt's own, which is why this is recorded as a membership rather than discarded as a shared host.
