Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability oneshot-agent-api-place-flood-zone-lookup-3998eb6c -d '<json body>'
```

Example prompt: What flood zone is the property at latitude 29.76 and longitude -95.37 in? I need to know if it's in a special flood hazard area and what the FIRM map ID is.

## When to prefer this

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.

## Known failure modes

- 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

## 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).
