data.gov (CKAN catalog)
The U.S. federal open data catalog at catalog.data.gov, powered by the open-source CKAN platform. The CKAN Action API at https://catalog.data.gov/api/3/action/ exposes dataset metadata (package_search, package_show, package_list), organization listings (organization_list, organization_show), groups, tags, and resource records. data.gov holds only metadata about datasets, not the underlying data — each dataset entry links out to the publishing agency's authoritative resource URLs (CSV, JSON, GeoJSON, Shapefile, SODA, REST).
data.gov (CKAN catalog) is one of 21 APIs that Public Sector publishes on the APIs.io network.
Tagged areas include Federal, Catalog, Open Data, CKAN, and Metadata. The published artifact set on APIs.io includes API documentation and a GitHub repository.
