KIT Library Catalogue REST API (self-hosted Koha)
The KIT Library self-hosts Koha, the open-source integrated library system, at katalog.bibliothek.kit.edu, and its REST API is live and served from KIT's own registrable domain. Verified 2026-09-01: /api/v1/ returns a 739 KB Swagger 2.0 document declaring host katalog.bibliothek.kit.edu, basePath /api/v1, 242 paths and 103 definitions, of which sixteen sit under /public and need no credentials. /api/v1/public/libraries answers 200 with KIT's own branch records (Bibliothek Campus Nord, service@bibliothek.kit.edu); staff endpoints such as /api/v1/libraries correctly answer 401. The DEPLOYMENT, the host and the data are KIT's. The CONTRACT is not: info.contact names the Koha Development Team at koha-community.org and the document ships identically with every Koha install, so it is recorded here and deliberately NOT saved under KIT's name. Koha's OAI-PMH provider is not enabled on this instance (/cgi-bin/koha/oai.pl returns a Koha error page).
