REST API

The Smarter Weather API provides a unified interface to weather data. All endpoints return JSON, serve errors as RFC 7807 problem details, and authenticate via an HTTP Bearer token.

Smarter Weather covers the 50 US states and DC only. Every route that takes a point (lat and lon, zip or location) returns 404 outside-coverage for a point outside the 50 states and DC. /v1/alerts and /v1/observations return it for a bounding box that touches no US domain (CONUS, Alaska, Hawaii); a box that touches one may still include area outside the US. /v1/weather/batch reports it per item as outside_coverage, and /v1/point with points and /v1/series/batch mark such points out_of_domain, as they do a point the check could not reach in time (retry it). If the location lookup is unavailable, the check can briefly fail open. Routes keyed by a station, radar site, forecast office or alert id, and nationwide lists, are not filtered by point, so do not treat an empty result as an all-clear. See Errors.
