How this service works
Official US National Weather Service forecast for coordinates in the United States: next 7 days or hourly, temperature (F and C), wind, chance of rain, plus active weather alerts.
Output
A JSON object containing the resolved place name, data source (US National Weather Service), timezone, any active weather warnings, and an array of forecast periods. Each forecast period includes a name (e.g. 'Today', 'Tonight'), temperature in Fahrenheit and Celsius, wind speed and direction, precipitation probability as a percentage, a short summary, and a detailed narrative description. Optionally includes hourly breakdowns.
Example use cases
Outdoor event planning weather check
“I'm planning an outdoor event at 37.7749° N, 122.4194° W this Saturday — can you pull the weather forecast including rain probability so I can decide whether to set up a tent?”
Travel itinerary weather lookup
“What's the weather going to be like in Miami at coordinates 25.7617° N, 80.1918° W over the next couple of days? I need temperatures and wind conditions.”
Agriculture field weather monitoring
“Pull the detailed weather forecast including hourly data for coordinates 41.8781° N, 87.6298° W — I need to know precipitation probability and wind speed for crop planning.”

Endpoint
POSThttps://api.vextorium.com/v1/us-weather?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured US weather forecasts sourced directly from the authoritative US National Weather Service (NOAA), without needing an API key. It is ideal for US-only location-based weather queries where you have latitude/longitude coordinates and want structured forecast data including precipitation probability, wind, and temperature in both Fahrenheit and Celsius. Prefer this over generic weather APIs when you need official government-sourced data for US locations at a very low per-call cost.
Side effects
- Coordinates outside the US (NWS only covers US territories) — likely returns an error or empty forecast
- Invalid or malformed lat/lon values — schema validation error
- NWS upstream outage — service unavailable or timeout
- Coordinates in remote US areas with no NWS grid coverage — empty or null forecast
- Missing required lat or lon fields — request rejected with validation error
