How this service works
Active weather alerts from the US National Weather Service (NOAA, public domain, real-time feed). Query: ?area=CA (2-letter state code) or ?point=34.05,-118.24; optional severity=Extreme|Severe|Moderate|Minor and event='Tornado Warning'. Returns up to 50 normalized alerts: event, severity, urgency, headline, affected areas, onset/expiry. count=0 means no active alert matches. 2 min cache.
Output
A list of up to 50 normalized active weather alerts including event type (e.g. 'Tornado Warning'), severity, urgency, headline text, affected areas, onset and expiry timestamps. If count=0, no alerts match the query. Data is cached for 2 minutes from the NWS real-time feed.
Example use cases
Example prompt
“Are there any active Severe or Extreme weather alerts right now in Texas? Show me the event names, headlines, and when they expire.”

Endpoint
GEThttps://x402-datashop-production.up.railway.app/v1/us/wx-alerts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time, authoritative active weather alerts from NOAA/NWS for a specific US state or location. Prefer it over general weather forecast APIs when the user's need is safety-critical alerting (watches, warnings, advisories) rather than temperature or precipitation forecasts. It covers all official NWS alert event types and severity levels.
Side effects
- Invalid or unrecognized state code returns empty results or error
- GPS point outside US territory may return no alerts
- Unrecognized event name string returns empty results
- Temporary NWS feed outage may cause stale or missing data
- Malformed point parameter (wrong format) returns validation error
