How this service works
US weather: give a latitude and longitude, get the National Weather Service forecast for the next 7 days (day and night periods: temperature, rain chance, wind, summary) and any active weather alerts for that spot. United States only. $0.003 per call; a location outside NWS coverage is not charged.
Output
An array of up to 14 consecutive 12-hour forecast periods (day/night alternating), each containing: period name, temperature, precipitation chance, wind speed and direction, and a short text summary. Also returns any currently active NWS weather alerts (e.g. tornado warnings, winter storm watches) for the queried location. Locations outside NWS coverage return an appropriate error and are not charged.
Example use cases
Outdoor event weather planning
“I'm hosting an outdoor wedding at 40.7128°N, 74.0060°W this coming weekend — can you pull the National Weather Service forecast for all 14 day and night periods and let me know if there are any active storm alerts?”
Agricultural field conditions check
“Pull the NWS weather forecast for my farm at 41.5868°N, 93.6250°W — I need temperature, wind, and rain chance for the next 7 days and any active weather advisories for that area.”
Hiking trip safety check
“Before I head out, can you get the National Weather Service forecast for 36.1069°N, 112.1129°W — give me the next 6 periods showing temperature, precipitation chance, and wind, plus any active weather alerts?”
Technical details
Endpoint
POSThttps://extract.tollkit.dev/weather?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official US government (NWS/NOAA) weather forecasts for a precise geographic coordinate, including active weather alerts, at very low cost per call. Prefer it over general weather APIs when NWS authority and alert data are important, or when you need granular day/night period breakdowns. Note it is strictly limited to locations within NWS coverage (United States and territories).
Side effects
- Coordinates outside the United States or NWS coverage area — returns an error, no charge applied
- Invalid latitude or longitude values (out of range or wrong type) — validation error
- NWS API upstream unavailability — temporary service error
- Periods parameter out of range (below 1 or above 14) — validation error
