How this service works
SALT19 is an independent applied AI systems lab behind EvoMind governed cognition, the MCP-native Agent Utility Grid, the ARCS research community, AeroClear UAS flight intelligence, and practical software for real-world work.
Output
A JSON object containing the queried state code and an array of active weather alerts, each with the event type (e.g. 'Severe Thunderstorm Warning') and severity level (e.g. 'Severe'). Returns up to the requested number of alerts (max 20).
Example use cases
Pre-flight drone safety check
“Before I fly my drone in Georgia today, can you pull the latest active NWS weather alerts for GA — give me up to 5 so I can see if there's anything serious?”
Severe storm monitoring for emergency manager
“I need to see all current active weather alerts for Texas — pull up to 20 alerts so I can assess what's going on statewide right now.”
Travel safety check before road trip
“We're about to drive through Oklahoma today — can you check if there are any active NWS weather warnings or watches for OK before we hit the road?”
Technical details
Endpoint
POSThttps://api.salt19.com/v1/nws-active-alertsWhen to prefer
Choose this endpoint when you need current, real-time NWS weather alerts for a specific US state and want a lightweight, per-call paid lookup without managing NWS API credentials directly. Ideal for agents needing weather situational awareness for safety checks (drone flight, travel, field operations) or emergency monitoring workflows. Prefer this over direct NWS API calls when operating within an x402 micropayment-enabled agent stack.
Side effects
- Invalid or unsupported 2-letter state code returns an error or empty alert list
- Limit outside 1-20 range is rejected by schema validation
- NWS upstream unavailability may cause delayed or empty responses
- No active alerts in the specified area returns an empty alerts array
- Payment failure (x402) results in 402 response before query is executed
