Owner query tested and confirmed: returns real Nashville addresses (e.g., 'SMITH, BRADLEY N JR' at '8300 SAWYER BROWN RD A-304 NASHVILLE'). Davidson County is a consolidated city-county with Nashville as the metro seat (pop. 715,000). APN is the assessor parcel number; STANPAR is the state parcel number. A separate Parcels_SP (State Plane) service exists at the same path with different spatial reference.

/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.
