How this service works
Official U.S. National Weather Service (NWS) forecast for the next period — the nearest upcoming forecast window, e.g. today, tonight, or tomorrow — at a given latitude/longitude. US locations only. Use /geo/lookup first if you only have an address.
Output
Returns the next forecast period from NWS including: period name (e.g. 'Tonight'), temperature with unit, short forecast summary (e.g. 'Partly Cloudy'), detailed forecast text, wind speed and direction, and the data source attribution.
Example use cases
Plan outdoor event weather safety
“I'm organizing a community picnic next Saturday at our local park in Austin — can you check the official National Weather Service forecast for that location so we know if we need to reschedule or prep for rain?”
Prepare delivery route conditions
“Before my delivery driver heads out to cover neighborhoods around Portland, Oregon, pull up the NWS forecast for those coordinates — I need to know the temperature, wind, and if there's any severe weather coming.”
Alert farm operations team
“We've got a big harvest planned tomorrow at our farm near Des Moines, Iowa — get me the official National Weather Service forecast for our property so I can tell the crew what conditions to expect and whether we need protective gear.”
Technical details
Endpoint
GEThttps://x402-seller.onrender.com/weather/forecastWhen to prefer
Use this endpoint when you need the authoritative, official U.S. government weather forecast for a specific US lat/lng coordinate and want structured next-period data including temperature, wind, and detailed narrative. Prefer this over commercial weather APIs when US government NWS sourcing is required. Use /geo/lookup first if you only have a street address and need to convert it to coordinates.
Side effects
- Coordinates outside the US return an error — endpoint only supports US locations
- Invalid or malformed lat/lng strings cause a 400-level error
- NWS API upstream outages may cause timeouts or 5xx errors
- Coordinates in US waters or territories may not have NWS grid coverage
- Missing required lat or lng query parameters returns validation error
