🇺🇸Government & Public Sector in United States

80 government & public sector providers in United States, publishing 52 APIs.

80 providers 52 published APIs 157 indexed documents

Government & Public Sector in United States — 80 providers on the APIs.io network sit in both cohorts, and between them they publish 52 indexed APIs.

32 of the 80 publish at least one machine-readable API; 48 publish nothing indexed at all. That split is the first thing worth reading here — a vertical can be well represented in a market and still have almost no programmable surface.

By Kin Score band: 39 emerging, 31 minimal, 5 thin, 4 developing, and 1 strong.

Leading by rating: LVT, Federal Aviation Administration, U.S. Department of Transportation, EIA, FERC, Weather.gov, and 74 more.

Country membership reads a tag or a stated headquarters. A provider lands in United States when one of its own top-level tags names the country, or when its own description states a headquarters that names the country or one of its cities (roadmap#542, #719). A description that calls a company by its nationality, or names a city in a phrase that is not a headquarters statement, is not counted, so this cell is a floor, not a census.
