# FEMA Disaster Declaration County Detail by Hurricane Event

> FEMA Disaster Declaration County Detail by Hurricane Event is a paid API for AI agents from api.querylines.com, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Returns per-county FEMA disaster-declaration details (declaration type/date, incident window, IA/PA program flags) for a specified U.S. hurricane event.

## 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-disaster-declaration-county-detail-by-hurricane-event-a038622f
```

Example prompt: Pull the FEMA disaster-declaration details for every county declared in Hurricane Ian — I need the declaration type, declaration date, incident window, and whether each county got Individual Assistance or Public Assistance.

## When to prefer this

Use this endpoint when you need structured, county-level FEMA disaster declaration data for a specific named hurricane, including program eligibility flags (IA/PA). It is purpose-built for insurance, risk, and catastrophe analytics workflows where knowing which counties received federal declarations — and what type — is essential. Prefer this over raw FEMA open data APIs when you want a clean, queryable record with pre-joined incident metadata.

## Known failure modes

- Missing or invalid 'event' query parameter returns an error — must use a valid event_key from /v1/cat/events
- Unknown event_key returns empty results or 404
- Invalid state code returns an error or empty county list
- Payment not processed (x402 flow) results in 402 Payment Required response
- Rate limiting or quota exhaustion returns 429

## How this service works

Per-county FEMA disaster-declaration detail for one U.S. hurricane (declaration type/date, incident window, Individual/Public Assistance program flags). Events from the free NOAA/FEMA catastrophe dataset. $0.10 per query. Free discovery: /v1/cat/events, /v1/cat/sample. Docs: https://api.querylines.com/openapi.json

## Output

A list of county-level records for the specified hurricane event, each containing the county name, state, FEMA declaration type (e.g. Major Disaster), declaration date, incident period start and end dates, and boolean flags indicating whether Individual Assistance (IA) and/or Public Assistance (PA) programs were activated for that county.
