University of Vienna
The University of Vienna (Universität Wien), founded in 1365, is Austria's largest university and ranks #78 in the QS World University Rankings 2025. Its public, programmatically accessible footprint centers on research and scholarly infrastructure rather than a unified developer portal: PHAIDRA, the university's institutional repository, exposes a documented REST(ish) API and an OAI-PMH metadata harvesting endpoint, and the institution's structured data is also published through the pan-European HEI API. Course, library discovery (u:find / u:search) and student-information systems are public web services but do not publish open developer documentation. No central, branded API developer portal or official GitHub organization was confirmed.
University of Vienna publishes 14 APIs on the APIs.io network, including datastream API, directory API, imageserver API, and 11 more. Tagged areas include Education, Higher Education, University, Research, and Repository.
The University of Vienna catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
University of Vienna’s developer surface includes authentication and 8 more developer resources.
