How this service works
Heat alert API: every Heat Advisory, Extreme Heat Warning, and Excessive Heat Warning currently active anywhere in the United States — affected zones, severity, urgency, and full alert text — as normalized JSON. Use for outdoor-labor safety, public-health notification, and event-cancellation agents. Public-domain government data, cached 5 minutes. Legitimately returns an empty list outside of active heat events.
Output
A normalized JSON list of all currently active US heat alerts (Heat Advisory, Extreme Heat Warning, Excessive Heat Warning), each with affected geographic zones, severity level, urgency level, event type, and full alert text. Returns an empty list when no heat events are active. Data is cached and refreshed every 5 minutes from NWS.
Example use cases
Example prompt
“Pull all the heat alerts that are currently active anywhere in the United States — I need the affected zones, severity, urgency, and full alert text so I can decide whether to cancel tomorrow's outdoor construction work.”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/heat-alertsWhen to prefer
Use this endpoint when you need a real-time, aggregated snapshot of all active US heat alerts in a single normalized JSON call — ideal for outdoor labor safety systems, public health notification agents, event management bots, or any workflow that needs to react to active heat emergencies without parsing raw NWS feeds. Prefer over scraping NWS directly since data is pre-normalized and returned as structured JSON.
Side effects
- Empty list returned when no heat alerts are active (not an error — legitimate state outside heat season or during mild weather)
- Payment failure if x402 USDC payment of $0.004 is not provided or rejected
- Network timeout if NWS upstream data source is slow or unavailable
- Stale data up to 5 minutes old due to cache refresh interval
