gov.hazard-mitigation

FEMA Hazard Mitigation Assistance (HMA) funded projects — the pre- and post-disaster mitigation grants FEMA has actually obligated (HMGP, BRIC/PDM, FMA). Filter by state (2-letter), disasterNumber, programFy (program fiscal year), and/or programArea; at least one filter is required. Returns the total matching project count plus projects (identifier, program area, project type, status, recipient/subrecipient, county, disaster number, project amount and federal share obligated in USD, cost-share %, benefit-cost ratio, number of properties, approval/close dates), largest federal share first. Free, public-domain (OpenFEMA). Distinct from gov.public-assistance (post-disaster recovery grants) and gov.nfip-claims (flood losses paid) — this is mitigation funding: who got money to reduce future risk, where, and at what benefit-cost ratio.

# 1. Probe with no auth → 402 envelope with PaymentRequirements
curl -sS 'https://2s.io/api/gov/hazard-mitigation?state=xx&disasterNumber=1&programFy=1989&programArea=example&limit=1'

# 2. Sign + retry with PAYMENT-SIGNATURE:
curl -sS 'https://2s.io/api/gov/hazard-mitigation?state=xx&disasterNumber=1&programFy=1989&programArea=example&limit=1' \
  -H 'PAYMENT-SIGNATURE: <base64-json-payload>'
