    summary: >-
      Verified a strong, real public API footprint. The USOS API for the
      University of Warsaw is well documented with 60+ services and an OAuth
      authorization flow; its documentation page resolved live (200). The Dane
      Badawcze UW research data repository is a live Dataverse instance whose
      native REST API version endpoint and OAI-PMH Identify verb both returned
      valid responses (200). The USOS developers/sign-up page returned 403 to
      automated probing (likely bot protection) rather than being dead. No
      endpoints were fabricated; only confirmed resources cataloged.
    endpoints:
