ATTOM Area API

  title: ATTOM Area API
  description: 'The ATTOM API (delivered as ATTOM Cloud) provides REST access to ATTOM Data Solutions'' national warehouse of property, real estate, and location data covering 158+ million U.S. properties. Resources are queried by address, APN + FIPS, ATTOM ID, radius around coordinates, or geoIdV4, and cover property characteristics, tax assessments, automated valuations (AVM), sales and deed history, mortgage records, area and boundary geographies, schools, community/neighborhood data, points of interest, transportation noise, consolidated all-event history, and home equity.

    Every request requires an API key passed in the `apikey` header. The URI pattern for the classic Property API is `{base}/propertyapi/v1.0.0/{resource}/{package}?{query}`; version 4 (v4) endpoints drop the component name and use a simplified `{base}/v4/{resource}` form. Area geography endpoints live under `areaapi/v2.0.0`.

    Endpoints under `propertyapi/v1.0.0` (property, assessment, avm, sale, saleshistory, salestrend, school, allevents, valuation) are grounded in ATTOM''s published endpoint reference. The v4 community, POI, area/boundary, and transportation-noise operations are modeled from ATTOM''s documented resource groups; confirm exact query parameters against the live docs.'
