How this service works
US weather forecast API: official National Weather Service forecast for any US lat/lon — next four periods (~48 hours, day/night): temperature, wind, short and detailed forecast text, plus resolved place name. UNITED STATES COVERAGE ONLY; points outside NWS coverage return an unpaid 404. Public-domain government data. Use for logistics, travel, and event-planning agents. Cached up to 10 minutes; nearby coordinates (within ~0.1°/11km) may share a cached forecast.
Output
A JSON object with up to 4 forecast periods (each with name like 'Tonight', temperature in °F, wind speed/direction, short forecast summary, and detailed forecast text), the resolved city/state location name, the NWS update timestamp, and cache metadata indicating whether the response was served from cache and when it was fetched.
Example use cases
Example prompt
“What's the official weather forecast for the next two days at coordinates 37.7749° N, 122.4194° W — I need temperature, wind, and a description for each day/night period.”
Technical details
Endpoint
GEThttps://gateway.stride20k.com/weather/us?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the official US government (NWS/NOAA) weather forecast for a specific US latitude/longitude — ideal for logistics, travel, and event-planning agents that need authoritative day/night forecasts for the next ~48 hours. Prefer this over commercial weather APIs when public-domain, attribution-free government data is acceptable and coverage is limited to the continental US, Alaska, Hawaii, and US territories with NWS grid coverage.
Side effects
- Coordinates outside US NWS coverage (e.g. international locations) return a 404 error
- Invalid lat/lon format or missing required query parameters returns a 400 error
- NWS upstream outage may cause delayed or failed responses
- Coordinates in US waters or territories without NWS grid coverage may return 404
- Cached responses (up to 10 minutes) may not reflect the very latest NWS update
