🇺🇸Real Estate in United States

96 real estate providers in United States, publishing 64 APIs.

96 providers 64 published APIs 213 indexed documents

Real Estate in United States — 96 providers on the APIs.io network sit in both cohorts, and between them they publish 64 indexed APIs.

20 of the 96 publish at least one machine-readable API; 76 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: 53 minimal, 29 emerging, 7 developing, 6 thin, and 1 strong.

Leading by rating: Spark Platform, Snappt, Fund That Flip, Lone Wolf Technologies, RESO (Real Estate Standards Organization), Trestle, and 90 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.
