    summary: >-
      Tokyo Metropolitan Open Data runs CKAN and exposes a live, standardized open-data catalog API. The
      endpoint was probed and returned a valid CKAN JSON response reporting approximately 9,675 datasets (CKAN version 2.11.4).
      Because it runs CKAN, the full standard action/search API surface is available and consistent with all other CKAN portals.
    endpoints:
