Changelog
A running record of new features, data sources, and API changes.
Peak Ground Acceleration (PGA) at 2% probability of exceedance in 50 years, queried live from the USGS Design Maps Web Service. Piecewise-calibrated 0–100 score reflects the actual US seismic hazard distribution.
Census-tract wildfire risk scores from the FEMA National Risk Index, covering all 50 states. Includes risk_rating (e.g. Very High) and normalized score.
Every hazard response now includes a score_basis string — a plain-English explanation of what drove the score (e.g. "FEMA zone AE", "PGA 0.087g", "62% of flood stage"). Designed for audit trails and underwriting workflows.
Previously limited to select regions. Full national FEMA NFHL coverage is now loaded and spatially indexed.
USGS river gauge readings now include flood_stage_ft and flood_stage_pct where NWS AHPS stage data is published, enabling meaningful river risk scores.
Score up to 50 locations in a single request. Responses include all hazards per location. Each location counts as one call against your quota.
Dedicated flood zone lookup returning FEMA zone, subtype, county FIPS, and risk score without the full multi-hazard payload.
Returns freshness and record counts for every data source. Useful for monitoring data pipeline health.
API key dashboard now shows calls used vs. monthly limit per key, sourced from Redis counters.
GET /v1/risk with flood (FEMA NFHL), air quality (EPA AirNow), and river gauge (USGS Water Services) hazards. Bearer token auth, Redis caching, rate limit headers.
No credit card required. Developer and Pro tiers available for higher volume.
