A lookup is one location with up to 50 fields; larger requests count one lookup per started block of 50 fields. Parcel records are 5 lookups per matched parcel and 25 lookups per search page of up to 100 parcels. Geocoding is free. Requests that return no data are not charged. Prices exclude any applicable sales tax, which is shown at checkout. Monthly plans renew until you cancel in the billing portal. How lookups and billing work.

What is free

What a lookup is

One location with up to 50 fields is one lookup. Asking for more fields counts one lookup per started block of 50, so 120 fields at one point is 3 lookups. A batch of 10 locations with 20 fields each is 10 lookups. Most presets, such as flood_risk or wildfire_underwrite, fit in one lookup.

Parcel records

A parcel enrich that matches a parcel is 5 lookups, plus the usual lookups for any point fields you ask for at the parcel. A parcel search page is 25 lookups whatever its size (up to 100 parcels). Parcels cover 35 states plus DC.

Common questions

Do I need a card for the free plan?

No. Sign up with an email address and you get an API key and 1,000 lookups every calendar month.

Do unused lookups roll over?

Monthly allowances do not. Top-ups last 365 days and are used only after your monthly allowance runs out.

Can I cancel?

Yes, anytime in the billing portal. Your plan stops renewing and you keep paid access to the end of the period you paid for, then move to Free.

Do AI apps cost extra?

No. Claude, ChatGPT and other apps connected through the MCP server use the same plans, lookups and limits as the REST API.
