Data.gov

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.

Kin Score

This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Data.gov

Each block below is one kind of artifact we hold for Data.gov. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

APIs 4

Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Security Posture 1

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
