Allen County IN (Fort Wayne metro, county seat Fort Wayne) provides parcels via gis.acimap.us — a combined City of Fort Wayne / Allen County GIS platform branded 'iMap'. The parcels/MapServer/0 layer is a lean 11-field service: PIN, GIS_ID, OwnerofRecord, PropertyAddress1, TransferDate, lat_add_pt, long_add_pt, Shape_Area, Shape_Length, Shape, OBJECTID. Owner and address search confirmed working: UPPER(OwnerofRecord) LIKE '%SMITH%' returns real results (e.g., 'Smith Halery W & Anna Catherine' on Pleasant Center Rd). The acimap.us server uses TLS renegotiation — direct curl calls may timeout on Windows; use HTTPS clients that handle renegotiation. The ASSESSOR folder at gis.acimap.us/services/rest/services/Assessor/ contains additional assessment data but requires authentication. Allen County IN (18003) must not be confused with other Allen counties.

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.
