ParcelKit is a property data API for Texas. It normalizes divergent county appraisal district (CAD) databases into a single JSON contract — covering valuation, ownership, flood risk, school districts, and spatial comparables — so you can ship real-estate features without scraping or maintaining county-specific parsers.
One address in. Structured data out. Every supported county returns the same fields, regardless of whether the upstream source is a REST API, ArcGIS feature server, or legacy HTML table.
