# FEMA events: declarations, flood claims, map revisions

`POST /api/locus_fema_events`

## Request

- Base URL: `https://api.locus.report`
- URL: `https://api.locus.report/api/locus_fema_events`
- Auth: none required

FEMA disaster declarations by county, NFIP flood claims by ZIP, and preliminary FIRM panels at a point. Accepts address, place, point, or state and county FIPS. For agents checking past declarations and claims; claims are ZIP-level, not parcel-level. National history and map status, not a prediction or quote.
Use this when you can call Locus free tools (REST tools/call or MCP).
Use locus-fema-events instead when your client can only call paid x402 routes; it returns the same records. Direct flat-body route for this one free resource; no API key, payment, or catalog wrapper. Return only the cited bounded evidence described here; this route never produces a paid brief or full report.

## Request body

- object
  - `address` string: Optional US street address; derives ZIP for NFIP claims and the point for preliminary-FIRM when geocodable. Explicit zip/lat/lng win over derived.
  - `state` string: Optional two-letter state code for disaster declarations; provide with countyFips3.
  - `countyFips3` string: Optional 3-digit county FIPS within state for declarations, e.g. 183 for Wake.
  - `zip` string: Optional 5-digit or ZIP+4 code for NFIP flood-claim history; overrides address-derived ZIP.
  - `latitude` number: Optional decimal latitude for preliminary FIRM panels; provide with longitude.
  - `longitude` number: Optional decimal longitude for preliminary FIRM panels; provide with latitude.

## Response `200`
