Property data API features

Look up one address, resolve a spreadsheet of them, or filter a whole county. Every response has the same shape in every county.

One format nationwide

Owners, values, sales and buildings use the same fields in every county, with the county's own codes kept beside them.

Search by address, number, point or area

Find parcels by street address, parcel number, owner, coordinates, a radius or a bounding box.

Batch lookups

Resolve up to 500 addresses, parcel numbers or points in one request, in the order you sent them.

Maps and GeoJSON

Parcel and zoning boundaries as GeoJSON, and vector tiles for both.

Monitors and webhooks

Watch a list of sites and receive a webhook when a permit or zoning case is filed on one.

Pay for results

1 credit per lookup and 1 per 20 search results. A repeat lookup within 24 hours is free, and so is a search that finds nothing.

Look up an address

Frequently asked questions

What data does the API return?
Parcels with owners, assessed values, sales, buildings and boundaries; zoning districts with their permitted uses and standards; building permits; and zoning cases with their decisions.
How do I authenticate?
Send your API key as a bearer token in the Authorization header. Create and revoke keys in the console.
Is there an OpenAPI specification?
Yes. The full OpenAPI document is published with the docs, so you can generate a client in any language.
What formats are supported?
JSON by default. Parcel and zoning searches also return GeoJSON, and both are available as vector tiles.
Can I use the data in my own product?
Yes, within your plan's terms. Contact sales to redistribute the data or for high volumes.
Does the API work with AI agents?
Yes. The MCP server gives Claude, ChatGPT, Cursor and other agents the same data, with the same credits.
