  2. New clients should use the v4 API instead of the older read-only CKAN endpoint and must send an api.data.gov key or limited DEMO_KEY. informative
  3. Catalog results contain dataset metadata, URLs, and descriptions rather than guaranteeing that the referenced data files are hosted by Data.gov. informative
  4. A catalog match is not evidence that a referenced resource is reachable, current, licensed for every use, complete, or endorsed by GSA. informative
