Results are sourced directly from the official weather.gov alerts feed.
Example use cases
Storm alert check before outdoor event
“Are there any Extreme or Severe weather alerts active in Tennessee right now? I need to know before we head out.”
Location-based alert for field crew
“Check for any active weather alerts near the point 29.76,-95.37 — that's where our crew is working today.”
Automated severe weather monitor
“Pull all active Tornado alerts across the US and give me up to 20 results so I can flag anything critical.”
Technical details
Endpoint
GEThttps://x402-data-api-x6da.onrender.com/v1/weather/alerts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, official US weather alert data from the National Weather Service, filterable by state, geographic point, event type, or severity. Prefer it over general weather APIs when the focus is on active hazard alerts (warnings, watches, advisories) rather than forecasts or current conditions. Ideal for safety-critical workflows where authoritative government data is required.
Side effects
- No alerts found for the given area/event/severity — returns empty list
- Invalid state/territory code returns 400 or empty result
- Invalid lat/lon format for point parameter causes error
- Payment failure or insufficient USDC balance prevents call
- Rate limiting or service unavailability on the upstream NWS API causes 503
