El Paso County (Colorado Springs metro, pop. 730,000) is the second-most populous Colorado county. Uses the same Colorado statewide composite endpoint as Denver — query by countyName='El Paso' or countyFips='041'. Owner query confirmed: returns real El Paso County results (e.g., 'SMITH CHERYL LYNNE'). See the Denver entry for full field list. Colorado OIT 3-digit FIPS for El Paso is '041' (full 5-digit is '08041').

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.
