  The University of Warsaw (Uniwersytet Warszawski) is Poland's largest and
  highest-ranked university, placed #258 in the QS World University Rankings
  2025. Its public developer footprint centers on the USOS API, a documented
  OAuth-secured REST-like protocol exposing the institution's academic database
  (courses, grades, exams, users, payments and more), and on the Dane Badawcze
  UW research data repository, a Dataverse instance that offers a native REST
  API and an OAI-PMH endpoint for metadata harvesting. Developer access to
  USOS requires registration for an API key (Consumer Key/Secret) via the USOS
  developers portal.
