University of Freiburg

The University of Freiburg (Albert-Ludwigs-Universität Freiburg) is a public research university in Freiburg im Breisgau, Germany, founded in 1457 and ranked #212 in the QS World University Rankings 2025. It does not operate a centralized public developer portal, but its university library (Universitätsbibliothek Freiburg) exposes several real, publicly reachable programmatic interfaces. The FreiDok plus institutional repository offers a JSON API and an OAI-PMH metadata-harvesting endpoint, and the FreiData research-data repository (built on InvenioRDM) provides a REST API. These are open, unauthenticated read endpoints intended for metadata harvesting and discovery rather than a formal developer program.

University of Freiburg publishes 3 APIs on the APIs.io network. Tagged areas include Education, Higher Education, University, Research, and Open Data.

The University of Freiburg catalog on APIs.io includes 1 JSON-LD context.
