gov.disaster-assistance

FEMA disaster assistance dollars — how much federal aid was approved or obligated for a declared disaster, by place. program=individuals (default) returns Individuals & Households Program (IHP) approved housing assistance, one record per ZIP per disaster, with FEMA-approved repair/replace, rental, and other-needs dollars and valid-registration counts (tenancy=owner default, or renter). program=public returns Public Assistance funded-project summaries, one record per applicant (state/local government, tribe, or eligible nonprofit) per disaster, with the federally obligated grant amount and project count. Filter by disasterNumber (the join key to gov.disaster-declarations), state (2-letter), and zipCode (5-digit, IHP only); results are ordered by approved/obligated dollars, highest first, with the total matching count and a normalized approvedAmountUSD per record. Free, public-domain (OpenFEMA). Distinct from gov.disaster-declarations (which disasters were declared + what was authorized), gov.risk-index (modeled future risk), and gov.nfip-claims (flood-insurance losses): this is the realized federal-spend record — for disaster-recovery, grants, insurance, and emergency-management workflows.

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/gov/disaster-assistance?program=individuals&tenancy=owner&disasterNumber=1&state=xx&zipCode=12345&limit=1'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/gov/disaster-assistance?program=individuals&tenancy=owner&disasterNumber=1&state=xx&zipCode=12345&limit=1' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'

# Or use the canonical runner (handles probe → sign → retry):
