🇺🇸Aerospace in United States

79 aerospace providers in United States, publishing 72 APIs.

79 providers 72 published APIs 168 indexed documents

Aerospace in United States — 79 providers on the APIs.io network sit in both cohorts, and between them they publish 72 indexed APIs.

20 of the 79 publish at least one machine-readable API; 59 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: 46 minimal, 24 emerging, 5 developing, and 4 thin.

Leading by rating: Federal Aviation Administration, American Express Global Business Travel, U.S. Department of Transportation, OpenTravel Alliance, Starlink, United Airlines, and 73 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.
