How this service works
Return the mapped flood hazard zone at a latitude and longitude in the United States.
Output
A JSON object containing: the FEMA flood zone code (e.g. 'X', 'AE'), the FIRM panel map ID, a boolean indicating whether the location is mapped, the zone subtype description (e.g. 'AREA OF MINIMAL FLOOD HAZARD'), base flood elevation in feet (null if not applicable), and a boolean indicating whether the location is within a Special Flood Hazard Area (SFHA).
Example use cases
Property purchase flood risk check
“Before I make an offer on this house, can you check if the coordinates 30.25 latitude, -97.75 longitude are in a FEMA special flood hazard area and what flood zone code it falls under?”
Construction site compliance review
“I need to know the flood zone classification for a construction site at latitude 25.77, longitude -80.19 — specifically whether it's in a high-risk zone and what the base flood elevation is.”
Real estate portfolio flood screening
“Can you look up the FEMA flood zone and FIRM map ID for the location at latitude 39.95, longitude -75.16? I want to know if it's a minimal hazard zone or something more serious.”

Choose this endpoint when you need authoritative FEMA NFIP flood zone classification for a specific geographic coordinate within the United States, particularly for real estate due diligence, mortgage compliance, insurance underwriting, or construction site assessment. It is pay-per-call with no API key required, making it ideal for agents that need ad-hoc lookups without subscription overhead.
Side effects
- Coordinates outside supported US range (latitude 17–72, longitude -180 to -64) — likely 400 error or empty result
- Location not covered by FEMA flood maps — mapped field returns false
- Invalid or missing latitude/longitude parameters — validation error
- Payment failure via x402 — request not processed
- Temporary FEMA data unavailability — server-side error
