**APIs profiled:** 4

Data.gov is the United States federal government's open data catalog, operated by the General Services Administration (GSA) Technology Transformation Services. It indexes over 300,000 datasets, tools, and resources from federal, state, local, and tribal governments, as well as universities and non-profits. The catalog runs on CKAN 2.11 and exposes the standard CKAN Action API at catalog.data.gov/api/3/action for programmatic discovery and retrieval of datasets, organizations, groups, tags, and resources. Data.gov also publishes the federal Project Open Data (POD) schema (data.json) catalog endpoint at /data.json on every federal agency site, which Data.gov harvests into the central catalog. Related properties include inventory.data.gov (publisher-facing CKAN inventory), resources.data.gov (open data policy resources), and the api.data.gov shared API gateway used by 25+ federal agencies for 450+ APIs.
