39 fields confirmed including PropID (numeric parcel ID), AcctNumb (BCAD formatted account number, e.g. '04126-236-0090'), Owner, Situs (situs address), AddrLn1/2/3, AddrCity, AddrSt, Country, Zip, Zip4, DBA, LglDesc, LandVal, ImprVal, TotVal, Nbhd (neighborhood code), GBA, TOT_GBA, YrBlt, Stories, NumRooms, Houses, Detached, State_cd, LglAcres, Acres, TaxUnits, Exempts, IS_UDI, UDIPARNT, Roll, SWP, PropUse. Owner LIKE search (including UPPER()) returns real results. The service description notes the data was sourced from BCAD FTP as of October 2022 and was last updated October 2021 — this is a periodic export, not a live feed. The current version is ArcGIS Server 11.3. The supportsQuery field shows null in layer-level metadata (common with this ArcGIS version); the service capabilities string 'Map,Query,Data' confirms query support. maps.bexar.org is the authoritative Bexar County GIS host; gis.bexar.org NXDOMAINs. BCAD's own server (bcad.org) does not expose a public REST parcel endpoint. maxRecordCount=1000. Texas SB247 privacy exemption may suppress certain owner names.

/query?where=…&outFields=*&f=jsonto the URL. 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.
