University of Bonn Search API

Search the published catalog of datasets, dataverses and files in bonndata. Re-verified live 2026-09-01: /search?q=*&type=dataset returned total_count 376 (362 at first profiling on 2026-06-03), and /search/services returned the single Solr-backed "Dataverse Standard Search" service. Anonymous, no key. The OpenAPI server base is https://bonndata.uni-bonn.de/api; the baseURL above names a verified endpoint instead, because /api itself has no index and returns 404.
