Technical details
Endpoint
POSThttps://twin.unykorn.org/geo/weather-alerts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, official NWS weather alert data for a specific US state, especially for safety-critical applications, travel planning, or monitoring severe weather events. Prefer this over general weather forecast endpoints when you specifically need official government-issued warnings, watches, or advisories rather than forecasted conditions.
Side effects
- Missing or invalid state code returns validation error
- State with no active alerts returns empty result set
- NWS upstream service outage may return error or stale data
- Limit parameter outside 1-100 range rejected with validation error
