Severe weather event data, as an API.

Answer “did hail hit this address on this date?” in one HTTPS call. Sourced from NOAA. Priced for property adjusters, roofing and restoration contractors, and the SaaS platforms they use.

    -H "Content-Type: application/json" \
    -d '{"address":"1234 Main St, Boulder, CO 80301","date":"2024-06-28"}'

What it isAn address-level lookup for severe weather

hail-path indexes public NOAA Storm Events data at the address level so property teams don’t have to. Give it an address and a date — we tell you what hit and how big.

The MVP covers hail across the continental United States from 2010 onward. Wind and tornado are next, then NEXRAD-derived radar swaths for the coverage NOAA’s ground reports miss.

EndpointsFour calls. That’s the whole API.

POST/events/search

All events matching an address and date window, ranked by distance and time.

  -d '{"address":"...","start_date":"2024-06-01","end_date":"2024-08-31","radius_km":5}'

POST/events/verify

Binary “did this happen here on this date?” — the high-volume adjuster call. Edge-cached 24h.

curl -X POST https://api.hail-path.com/v1/events/verify \

CoverageWhat’s in, what’s next

Today: hail events, continental US, 2010 to present. Backed by NOAA’s Storm Events Database. New events land within 7 days of NOAA’s monthly publication.

Next: wind and tornado (same source), then NEXRAD radar-derived hail swaths for the storms nobody was outside to report.
