Paste up to 100 addresses, one per line. Get hail days, the most recent hail date and the nearest radar detection for each — then download the lot as a CSV. Free, no login, no daily cap.
What a result does and does not tell you. Hail days describe a 0.1° grid tile about 7 miles tall around each address, not a rooftop. The nearest-detection distance is much more specific — it is the reported centroid of a detected storm cell — but a cell is a volume of air aloft, its position error grows with distance from the radar, and hail drifts as it falls. A clean result is a real answer, not a failure: it means radar registered nothing over that tile in the period, which is not the same as proof nothing fell. None of this is a damage assessment. Somebody still has to look at the roof.
This runs in your browser against our free public API, which calls NOAA. We pace requests deliberately — roughly one address per second — because NOAA publishes no rate limit and that is not the same as there being none. 100 addresses takes about two minutes with distances on, under one without. Nothing is stored: close the tab and it is gone.
The API is free and keyless with CORS open, so you can call it directly from a script or a spreadsheet without going through this page. If you need something this page does not do — scheduled runs, branded PDFs, a territory watch list — tell us; that page is also where contractors claim a city for leads.
