How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object with the queried state code, total alert count, and an array of alert objects — each containing an alert ID, affected geographic areas, event type (e.g. Heat Advisory, Wind Advisory), onset and expiry datetimes, urgency level, severity level, and a human-readable headline from the issuing NWS office.
Example use cases
Heat advisory check for travel planning
“Are there any active heat advisories or extreme weather alerts in Arizona right now? Give me up to 5 results.”
Emergency operations dashboard feed
“Fetch all current NWS weather alerts for Texas — I need the event name, severity, affected areas, and expiry times for our ops team.”
Automated state-level weather monitoring
“Check for any active weather warnings or advisories in Florida and tell me how many there are and what types.”
Technical details
Endpoint
GEThttps://x402-agent.kariguetoazul.workers.dev/api/data/us-weather-alerts?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, real-time NWS weather alert data for a specific US state, especially for emergency dashboards, travel safety checks, or automated alerting pipelines. It is preferable when you need a paid, reliable API wrapper around the NWS alerts feed with a predictable schema and bounded result set rather than parsing the raw NWS API yourself.
Side effects
- Missing or invalid area code (not two uppercase letters) returns a validation error
- area code for a non-US state or territory not covered by NWS may return empty results
- limit parameter outside 1–20 range is rejected
- NWS upstream API downtime may cause timeouts or empty responses
- Payment of $0.003 USDC required per call; insufficient funds or missing x402 payment header returns 402
