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 list of currently active NWS alerts matched to the point and window (may be empty), the count of matched/examined/unknown alerts, a flag indicating whether results were truncated, the requested time window echoed back, source metadata including the NWS API URL and retrieval timestamp, and a list of data limitations (e.g. no historical archive coverage, no independent geometry guarantee).
Example use cases
Outdoor event weather safety check
“I'm planning an outdoor concert at latitude 36.17, longitude -86.78 from 6 PM to 11 PM this Saturday — can you check whether any NWS weather alerts are active for that location during that window, say 2025-08-02T23:00:00Z to 2025-08-03T04:00:00Z?”
Drone flight go/no-go alert screening
“Before we launch a drone at 47.61 latitude, -122.33 longitude, check if NOAA has any active weather alerts for that point between 2025-07-20T16:00:00Z and 2025-07-20T20:00:00Z.”
Insurance claim weather corroboration
“A client filed a weather damage claim for a property at latitude 29.76, longitude -95.37. Can you check whether NWS had any active alerts for that location during the window 2025-06-10T00:00:00Z to 2025-06-10T12:00:00Z, and give me the source URL and attribution?”
Technical details
Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/nws-alert-interval-relevanceWhen to prefer
Use this endpoint when you need official, source-attributed NWS weather alert coverage for a specific geographic point and time interval — particularly for go/no-go decisions, event safety checks, or audit trails requiring explicit provenance. Prefer this over generic weather APIs when you need the raw alert match count, limitation disclosures, and NOAA attribution in a structured JSON contract. Not suitable for historical alert archives or future forecast alerts beyond what NWS currently exposes as active.
Side effects
- Invalid or out-of-range latitude/longitude returns a validation error
- Malformed ISO 8601 datetime strings rejected by the pattern validator
- NWS upstream API unavailability may result in empty or stale responses
- No alerts returned does not confirm safe conditions — stated explicitly in limitations
- Time window outside current NWS active alert horizon returns empty results with historical_coverage: NOT_AN_ARCHIVE
- Missing temporal fields in NWS alerts result in UNKNOWN status counts rather than definitive matches
