Frequently asked

What data does the ParcelGeo API return?

Parcel records for 130M+ US properties: owner of record, USPS-shaped mailing address, situs address, market/assessed value, land use, acreage, sale data where available, and census-tract demographics (income, owner-occupancy, education). Vector map tiles are included for building map UIs.

How much does the API cost?

API access is included in the Scale plan at $299/mo (or $2,990/yr) with 25,000 calls a month — no per-seat pricing, no enterprise minimums, cancel anytime. Compare that to legacy providers that start at four figures with annual contracts.

How do I authenticate?

Send your API key in the x-api-key header. Keys are created in the dashboard on the Scale plan and can be rotated or revoked at any time.

Is there a free way to evaluate the data?

Yes — the interactive map explorer is free (no card): browse any US neighborhood and open parcel records to inspect exactly the fields the API returns. Grab a free 10-lead sample export to test the CSV shape.

Are there usage restrictions?

ParcelGeo is not a consumer reporting agency; the data may not be used for FCRA-regulated decisions (credit, employment, tenant screening, insurance). Owner names are withheld where state law requires. See the Acceptable Use policy.
