## 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 floodpulse-flood-risk-lookup-bd57d32e
```

Example prompt: What's the flood risk for 123 Bayshore Drive, Houston, TX 77058 — I need the FEMA flood zone, whether it's in a special flood hazard area, and the annual and 30-year flood odds.

## When to prefer this

Use FloodPulse when you need a comprehensive, single-call flood risk profile for a US property that combines FEMA zone classification, SFHA status, probabilistic flood odds (annual and 30-year), elevation data, and FEMA NRI ratings in one response. Prefer this over raw FEMA map lookups when you need structured, machine-readable risk scores and probability estimates — particularly for real estate due diligence, insurance underwriting, mortgage compliance, or property disclosure workflows.

## Known failure modes

- Address not found or outside the US — returns error or null data
- Invalid or unparseable address string — may fail geocoding
- Lat/lon provided without companion coordinate — returns validation error
- Property in area with incomplete FEMA mapping — some fields may be null
- Network timeout or upstream FEMA/elevation data unavailability — 5xx error
- Payment not completed (x402 protocol) — 402 Payment Required before data is returned
