🇺🇸Defense in United States

75 defense providers in United States, publishing 17 APIs.

75 providers 17 published APIs 23 indexed documents

Defense in United States — 75 providers on the APIs.io network sit in both cohorts, and between them they publish 17 indexed APIs.

9 of the 75 publish at least one machine-readable API; 66 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, 16 emerging, and 3 thin.

Leading by rating: PreVeil, Urban Sky, Teledyne Technologies, Electra.aero, Blue Origin, Neros, and 69 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.

This page is the intersection of two independently computed cohorts: United States and Defense. A provider appears here only when it is already a member of both. United States membership is matched on tag, stated HQ, so this is a floor rather than a census — coverage gaps show up here as small numbers, not as absent pages.

Work with this as data

Every country here is available over the APIs.io API and to AI agents over MCP. Countries is not yet its own endpoint on the v1 API. Reach it through catalog search and the tag graph, or the MCP server.
