GeoClear

About

GeoClear provides FEMA flood zones, census tract information, county FIPS codes, RDI data, and timezone details for any US address through one API call. It covers over 198 million addresses. A free tier offers 10,000 monthly calls with no credit card required, while paid plans start at $49 per month. There is no need to separately combine the Census Bureau geocoder and the FEMA NFHL API, as we have completed that integration. You receive a single, clean JSON response. The service is built on data from USDOT NAD, Overture Maps, FEMA NFHL, and the US Census Bureau.
