🇺🇸Aerospace in United States

96 aerospace providers in United States, publishing 264 APIs.

96 providers 264 published APIs 265 indexed documents

Aerospace in United States — 96 providers on the APIs.io network sit in both cohorts, and between them they publish 264 indexed APIs.

27 of the 96 publish at least one machine-readable API; 69 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: 56 minimal, 24 emerging, 8 thin, 4 strong, and 4 developing.

Leading by rating: Sift Stack, FlightAware, Tomorrow.io, Federal Aviation Administration, American Express Global Business Travel, Starlink, and 90 more.

Country membership reads a tag, a stated headquarters or a stated nationality. A provider lands in United States when one of its own top-level tags names the country, when its own description states a headquarters that names the country or one of its cities, or when it describes itself by nationality (“a French company”; roadmap#542, #719). Region words (“Latin American”), language uses (“French-speaking”) and a city named outside a headquarters statement are not counted, so this cell is a floor, not a census.
