ParcelKit normalizes 60+ Texas CAD portals into a single JSON contract. Each county runs its own upstream provider strategy — ArcGIS FeatureServer, TrueProdigy API, BIS HTML, or hybrid — while returning identical response fields.
ArcGIS FeatureServer
Direct spatial query against county GIS portals. Lowest latency. Harris, Nueces, Jefferson, and others.
TrueProdigy API
REST-based CAD API. Structured JSON from Denton, Travis, Hidalgo, and 8 others.
BIS HTML
HTML scrape of county BIS portals. Widest county coverage — 25+ counties including Galveston, Brazoria, Collin.
Hybrid HTML + GIS
BIS HTML for owner/property data, ArcGIS spatial layer for neighbor queries. Bexar, Dallas, Fort Bend, Waller.
The /api/counties endpoint pings each upstream CAD portal and returns current latency and health. Use it to build status dashboards or route around degraded providers at runtime.

-H "x-api-key: sk_live_your_key"County coverage expands continuously. If your target county isn't listed, open an issue or reach out — most BIS-based CADs can be added within a day.
