How this service works
Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.
Output
Returns a JSON object containing the queried state/territory, a list of normalized active NWS alert records (up to the requested limit) with fields for severity, urgency, expiry, and official source identifiers, plus freshness metadata including retrieval timestamp, cache age, provenance/attribution details, and a link to the upstream NWS API source.
Example use cases
Pre-travel severe weather check
“Before I drive through Oklahoma tomorrow, can you pull up all active NWS weather alerts for OK so I know if there are any tornado warnings or severe thunderstorm advisories in effect?”
Emergency dashboard for hurricane season
“I'm monitoring storm conditions along the Gulf Coast — fetch the latest 20 active NWS alerts for Florida and show me the severity, urgency, and expiry for each one.”
Winter storm alert monitoring for logistics
“We have deliveries going through Wyoming today — can you check if there are any active NWS weather alerts for WY, especially any blizzard or ice storm warnings?”
Technical details
Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/nws-active-alertsWhen to prefer
Choose this endpoint when you need current, authoritative NWS weather alert data for a specific US state or territory in real time, especially for safety-critical decisions, logistics, travel planning, or automated monitoring workflows. It normalizes raw NWS data into a consistent schema with freshness metadata and attribution, making it more agent-friendly than calling the NWS API directly. Prefer this over general weather forecast endpoints when the specific need is official government-issued alerts (warnings, watches, advisories) rather than forecast conditions.
Side effects
- Invalid or unsupported state/territory code returns a validation error
- NWS upstream API unavailability may result in stale or empty results
- Result count capped at 20; more alerts may exist but won't be returned
- No alerts active for a state returns an empty normalizedResult array
- Payment failure (x402) blocks access before any query is made
