FEMA federal disaster & emergency declarations — every federally declared disaster since 1953, including the ones declared this week. Filter by state (2-letter), disasterNumber, declarationType (DR=major disaster, EM=emergency, FM/FS/FW=fire management), incidentType (e.g. Hurricane, Fire, Flood, Severe Storm), county (5-digit FIPS), fiscal year (fyDeclared), and declaration date range (fromDate/toDate, YYYY-MM-DD). With no filter, returns the most recent declarations nationwide. Returns the total matching count plus records (one per designated county/area) with the declaration string, disaster number, title, incident type, declaration + incident begin/end + closeout dates, designated area, county FIPS, FEMA region, and the assistance programs authorized (Individuals & Households, Individual Assistance, Public Assistance, Hazard Mitigation). Free, public-domain (OpenFEMA). Distinct from gov.risk-index (modeled future risk) and gov.nfip-claims (realized flood losses): this is the official federal-response record — for disaster-response logistics, eligibility checks, insurance, and emergency-management workflows.
/api/gov/disaster-declarationsPAYMENT-SIGNATURE.The disaster declarations API is a pay-per-call gov endpoint built for AI agents and autonomous software. FEMA federal disaster & emergency declarations — every federally declared disaster since 1953, including the ones declared this week.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in disaster declarations data source for an agent tool-use loop, an MCP host, or a backend that needs gov data on demand without onboarding to yet another vendor portal.
