How this service works
A one-page hail report for a US address and date to share with a homeowner, adjuster or contractor: verdict, largest radar hail estimates by distance, a map of hail sizes within 10 miles, radar hail signatures in time order (when it fell), spotter reports, and NOAA's final Storm Events record with damage notes when published. Returns a private link valid for 1 year. Not found addresses are not charged.
Output
A JSON response containing a hail verdict (e.g. 'hail_likely'), NOAA MRMS radar hail size estimates at the location and within 1, 3, 5, and 10 miles, radar NEXRAD signatures with timestamps, local spotter reports with sizes and distances, NOAA Storm Events damage notes when available, and a private shareable report URL valid for one year.
Example use cases
Insurance claim hail verification
“I need a hail report for 4521 Oak Ridge Dr, Norman, OK 73072 for July 10, 2023 — I'm filing a roof damage claim and need to show the adjuster what the radar and spotter data say.”
Contractor pre-inspection hail check
“Before I go out to inspect a roof, can you check whether there was hail at 88 Maple Ave, Springfield, IL 62701 on August 3, 2024 and get me a link I can show the homeowner?”
Homeowner storm damage review
“We had a bad storm here at 37.1 latitude, -88.96 longitude on May 16, 2025 and I think it hailed — can you generate a hail report so I know the largest hail size and when it fell?”

Endpoint
POSThttps://hail.kagurazaka.dev/v1/hail/report?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a complete, shareable hail verification report for a specific US address and date — particularly for insurance claims, contractor inspections, or homeowner documentation. It aggregates NOAA MRMS radar estimates, NEXRAD signatures, spotter reports, and Storm Events into a single human-readable report link, making it superior to raw NOAA data lookups when a presentable artifact is required. Best for single-event, single-address queries where you need both data and a deliverable link.
Side effects
- Address not found or outside the US — not charged, returns error indicating unmatched address
- Date before 2020-10-14 — outside supported historical range
- No radar coverage for the requested date/location — may return 'no_hail' verdict with coverage flag false
- Invalid date format — returns validation error
- Missing both address and lat/lon — returns schema validation error
