PropData U.S. Property API

Resolve any U.S. address, parcel or coordinate into production property intelligence.

166M+indexed U.S. parcels
20+documented production routes
8MCP tools for AI clients

Overview

PropData resolves addresses, parcel identifiers and coordinates against 166M+ indexed U.S. parcels and returns assessor, valuation, tax, sale, geometry, comps, rent and market context, with source-level provenance on every response. The same key reaches the shared-gateway international adapters for Great Britain, New Zealand, France and Spain with country=.

Property resolutionAddress, parcel ID or coordinates to one normalized property record with provenance.
GeometryCounty-sourced parcel boundaries as GeoJSON and coordinate-to-parcel lookup.
Valuation & compsRanked comparables, AVM rent estimate and listing-market statistics.
Market & communityZIP, state and census-tract intelligence; Community Intelligence on Builder+.
Change feedsProperty and pre-foreclosure deltas since a timestamp for sync pipelines.
International on one keyGreat Britain, New Zealand, France and Spain through country= on the same gateway.

Integration ideas

  • Lending & underwriting. Resolve the collateral, pull tax and sale history, and attach comps in one integration.
  • Investor tooling. Screen ZIPs and states, then enrich candidate properties with rent and valuation context.
  • AI agents. Give Claude or ChatGPT live property lookups through the included MCP connector.

Coverage & limits

United States: 166M+ indexed parcels across the 50 states and DC; field depth varies by county source.

  • Assessor, valuation, tax and sale fields where the county publishes them
  • Parcel geometry where a spatial source is configured (see /v1/property/coverage)
  • Pre-foreclosure filings in Harris County TX, Hillsborough County FL and Johnson County KS
  • Nationwide property and pre-foreclosure change feeds
  • Nullable fields mean the connected official source did not return that attribute
  • Ownership contact enrichment (/v1/skip-trace) is Builder and above
