## 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 fema-national-risk-index-flood-zone-lookup-67da1b28
```

Example prompt: What's the full FEMA natural hazard risk profile for 742 Evergreen Terrace, Springfield, IL — I need the composite risk index, expected annual loss, social vulnerability score, and whether it's in a flood zone.

## When to prefer this

Use this endpoint when you need an authoritative, government-sourced natural hazard risk assessment for a specific US property or location. It is the right choice for real estate due diligence, insurance underwriting research, emergency planning, or any scenario requiring official FEMA data on 18 hazard types plus flood zone designation in a single call. Prefer this over generic third-party risk scores when official FEMA provenance and citation are important.

## Known failure modes

- Address not geocodable or not found in the US — returns error indicating geocoding failure
- FIPS code invalid or not matching a known county or census tract — returns validation error
- Coordinates outside the continental US, Alaska, Hawaii, or US territories — may return no data or partial data
- Missing required input (no address, lat/lon, or FIPS provided) — returns 400-level error
- FEMA NRI data not available for the specific census tract — partial result or null fields

## How this service works

US property/location natural-hazard risk profile: FEMA National Risk Index composite (18 hazards, expected annual loss, social vulnerability) plus the FEMA flood zone, as one cited JSON verdict for a US address, coordinates, or FIPS.

## Output

A JSON object containing the FEMA National Risk Index composite score, individual scores for up to 18 natural hazards (e.g. earthquake, hurricane, wildfire, tornado, flood), expected annual loss in dollars, social vulnerability index, community resilience metrics, and the property's FEMA flood zone designation — all cited to official FEMA data sources.
