Live: POST api.hail-path.com/v1/events/verify — no key required. Leave date empty for "any recent hail" (last 2 years); fill it in to verify a specific storm date.

What it is

Address-level severe weather, one HTTPS call.

NOAA’s data is free — why pay? The CSVs are yours for the taking. Joining storm-event geometry to a specific street address, deduping across county reports, versioning as NOAA re-publishes, and serving it with a real SLA is the actual product. That is what you are outsourcing to hail-path.

CoreLogic and Verisk already exist. Yes — at 10–50× the price, sales-led, contract-bound, and dashboard-first. hail-path is the self-serve API in the shape those vendors will not quote to a two-person SaaS or a solo integrator.

The API

Four calls. That’s the whole thing.

# verify — the high-volume adjuster call
$ curl https://api.hail-path.com/v1/events/verify \

         "date":"2023-05-09"}'
