-H "X-API-Key: ht_live_xxxxxxxxxxxx"How accurate is the hail size data?
MESH (Maximum Estimated Size of Hail) is radar-estimated at ~1km resolution. It's the best available automated hail measurement. We include distance_miles and source fields so you know exactly what you're working with.
What's the difference between MESH and Storm Events data?
MESH comes from NOAA NEXRAD radar — precise coordinates, available from 2020. Storm Events comes from NOAA's curated database — county-level, back to 1950, includes ground reports and damage data.
What states are covered?
All 48 continental US states (CONUS) with full NEXRAD radar coverage.
How fresh is the data?
MESH data is ingested nightly from NOAA's public S3 bucket. Storm Events data is updated monthly when NOAA publishes new CSV files.
What counts as a 'lookup'?
Each call to /v1/hail/address or /v1/hail/coordinate counts as one lookup. Calls to /v1/account/usage do not count.
Can I cancel anytime?
Yes. Cancel through the Stripe billing portal — no lock-in, no cancellation fees.
