How this service works
US weather forecast API for agents: return a normalized National Weather Service (NOAA/NWS) multi-period forecast for $0.001 USDC from latitude/longitude only—US coverage, attributed periods, no arbitrary URL proxy and no global weather claim.
Output
A JSON object containing an array of normalized NWS forecast periods, each with a period name (e.g. 'Tonight', 'Monday'), temperature, wind, short forecast description, and attribution to the National Weather Service. Up to 10 periods returned depending on the 'periods' parameter.
Example use cases
Trip planning weather check
“Can you pull the NWS forecast for the next 7 periods for coordinates 40.7128, -74.0060? I want to know what the weather will be like in that area.”
Outdoor event weather planning
“Get me the next 10-period NWS forecast for latitude 34.0522, longitude -118.2437 — I need to know if conditions will be safe for an outdoor event.”
Field operations weather briefing
“What does NOAA say the weather will be for the next 3 forecast periods at 44.9778 latitude and -93.2650 longitude?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/weather-forecastWhen to prefer
Choose this endpoint when you need official US government (NOAA/NWS) weather forecast data for a specific US latitude/longitude, especially when accuracy and attribution matter. Prefer this over general weather APIs when you need authoritative NWS data, multi-period structured forecasts, and are guaranteed to be working within US geographic coverage. At $0.001 USDC per call it is cost-effective for per-request lookups.
Side effects
- Coordinates outside the US (including non-US territories not covered by NWS) return an error — NWS only covers US land area
- Invalid latitude/longitude values (out of -90 to 90 / -180 to 180 range) cause a validation error
- NWS upstream API timeout or unavailability may cause timeout errors (max 8 seconds)
- Ocean or offshore coordinates not covered by NWS grid will return a not-found error
- Requesting more than 10 periods returns a validation error
