- The site says its NWS alert endpoint resolves zone polygons that the official feed leaves unresolved for 97% of alerts.
Field notes
Alongside the radar layers, the page documents three coordinate-based JSON routes: point forecasts, active NWS alerts as GeoJSON, and historical conditions reaching back to 2013. The alert route says it resolves warning-zone polygons that the official feed leaves unresolved for most alerts; the page quantifies that as 97%. Trial accounts are listed at 500,000 requests for 14 days, with errors such as 401s and 404s excluded from billing.
