56 fields confirmed including OWNER_NAME, SITUS_ADDR, OWNER_ADDR, DEED_DATE, DEED_BOOK, DEED_PAGE, YEAR_BUILT, LIVING_ARE, BEDROOMS, BATHROOMS, SW_POOL, LAND_ACRES, APPRAISEDV, LAND_VALUE, IMPR_VALUE, TOTAL_VALU. Owner query returns real results. Some records may not appear in UPPER() LIKE queries due to the SB247 privacy flag on certain Texas property owners — drop UPPER() for broader results when needed. A sibling TADParcelsApp/MapServer/0 exists but only has TAXPIN (geometry-only layer for the appraisal district viewer).

The sample query above is a working example you can paste into a browser tab to see the raw JSON response.Counties publish parcel data through their own ArcGIS Server installations, each with its own schema. One county uses APN, another uses PIN, a third uses PARCEL_ID. Some expose owner names; others keep them on a separate assessor's portal. The searchable fields list above reflects what this county actually publishes — not what you might expect from a national standard (there isn't one).
For background, see What is an APN?
Many county servers allow public reads but block browser cross-origin requests. The UrbanKit parcel lookup tool fetches directly from your browser; if it works there, the layer is technically public. For your own integration, you may need a same-origin proxy or server-side fetch.
Possibly — counties move services without warning. We re-verify entries weekly and flag stale ones. If you're seeing a fresh 404, please let us know and we'll update the listing.
Most are. Public ArcGIS layers don't typically rate-limit individual reads, but heavy programmatic use can trigger throttling at the host level. Be respectful — query what you need.
