Shawnee County KS (Topeka metro, county seat and state capital Topeka) provides AppraisalDataPro/MapServer/4 (Current Parcels) via the county appraiser's GIS server. This is a 20-field service: OBJECTID, PARCELNUM, ACRES, PID, QUICKREFID, ONAME (owner name), PADDRESS, PADDRESS2, DBOOKPAGE, SUBS (subdivision), NBHD (neighborhood), TAXUNIT, USD (unified school district), LBCSFUNCTION, LBCSACTIVITY, LDVAL, BLDGVAL, TOTVAL, Shape, Shape area. Query confirmed live: UPPER(ONAME) LIKE '%SMITH%' returns real results (e.g., 'SMITH, NEIL K & JONI' on SE 105TH ST). The same service has layer 0 (Parcel Information with Labels), layer 3 (Parcels 1-1-2024, prior year snapshot), and layer 4 (Current Parcels). The Shawnee County Open Data Portal at data-sncoks-gis.opendata.arcgis.com provides additional datasets. The property search app is at gis.sncoapps.us/propertysearch/. Shawnee County KS (FIPS 20177) must not be confused with Shawnee County Ohio or Shawnee Township. NOTE 2026-06-27: query endpoint responds in 13-35s (server-side slowness. Returns 437,436 features when polled with 35s timeout); liveness check at 12s flags FAIL but endpoint IS live. Metadata returns immediately.

Shawnee County's Current Parcels layer exposes parcel identifiers (Parcel Number, Parcel ID), owner names (Owner Name), and address fields (Property Address, Property Address 2). Use it for owner-name lookups and address-based parcel searches. 6 of 7 listed fields accept queries; the rest are returned on read but not indexed for search. Served as an ArcGIS MapServer layer, which supports query operations but not write operations; last verified 2026-06-27.

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 Shawnee County actually publishes, not what you might expect from a national standard (there isn't one).

gis.sncoapps.us serves Shawnee County, Kansas parcels over public ArcGIS REST, but, like most county servers, it may not send the CORS headers a browser needs for a cross-origin fetch. If a direct browser call fails, the layer still works from curl, Postman, or a server-side script; the UrbanKit parcel lookup tool proxies the request, so a search that succeeds there confirms the layer is genuinely public.
We last verified Shawnee County's MapServer layer on 2026-06-27. County GIS teams move services without notice, so if you hit a fresh 404, tell us and we'll re-check. Atlas entries are re-verified on a rolling basis.
Shawnee County's layer is hosted by the county on gis.sncoapps.us. Public ArcGIS endpoints rarely rate-limit individual reads, but gis.sncoapps.us can throttle heavy automated traffic at the host level. Page through results with resultOffset / resultRecordCount and request only the fields you need. There's no API key and no charge from the county.
