Hosted on ArcGIS Online (services7.arcgis.com) — the county's WAB viewer config points at this FeatureServer as the backing data layer. 27 fields total including Parcel_Number, Owner, SiteAddress, MailingAddress, tax_code, net_taxable_value, Zone_Code, and QTAS/Compass hyperlinks. Owner-name search by UPPER() LIKE works. The public-facing viewer at spatial.dekalbcounty.org uses VertiGIS/Geocortex as the front-end.

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.
