How this service works
Verify a claim or fact check a statement against public web sources: send a question and up to 5 URLs, get cited evidence - passages that support, contradict or fail to settle it. Claim verification with a citation for every excerpt: source URL, retrieval time, content hash. Never charges when nothing is retrieved. Free to evaluate: the `sample` tool returns one real response at no cost, so you can judge the output before paying for your own question.
Output
A list of active National Weather Service alerts for the specified state, each containing the event name (e.g. 'Tornado Warning'), the affected geographic area, the severity rating (e.g. Extreme, Severe, Moderate), and the official NWS instruction or recommended action for residents.
Example use cases
Real-time storm warning check
“Are there any tornado or severe thunderstorm warnings active in Oklahoma right now? I need the event type, area, severity, and what people should do.”
Emergency preparedness app alert feed
“Pull all current NWS weather alerts for Florida — I need to know what events are active, how severe they are, and the official guidance for each.”
Travel safety check before trip
“I'm about to drive through Louisiana this weekend — can you check if there are any active weather warnings or advisories I should know about?”

Endpoint
POSThttps://agent-evidence-api.thx93.workers.dev/v1/weather/alerts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, official NWS weather alert data for a specific US state, including severity and actionable instructions. Prefer this over general weather forecast endpoints when the use case involves safety monitoring, emergency awareness, or alert notification rather than temperature or precipitation forecasts.
Side effects
- Invalid or unrecognized state code returns an error or empty result
- No active alerts returns an empty alerts array (not an error)
- NWS API upstream outage may cause timeout or 5xx response
- Malformed request body (missing state field) returns a 400-level error
