How this service works

Multi-period weather forecast for a US location from api.weather.gov (NWS, public domain). Give latitude and longitude; returns the place plus upcoming forecast periods (temp, wind, conditions). US coverage only.

Output

Technical details

Endpoint

GEThttps://agent402.tools/api/weather-forecast?utm_source=zero.xyz

When to prefer

Use this endpoint when you need a structured multi-period weather forecast for a US location and have latitude/longitude coordinates available. It pulls directly from the authoritative US National Weather Service (api.weather.gov), making it ideal for government-sourced, public-domain forecast data. Prefer this over commercial weather APIs when NWS data is sufficient and US-only coverage is acceptable.

Side effects

Coordinates outside the US return an error or no forecast data (US-only coverage)
Invalid or missing lat/lon parameters return a 400-style error
NWS API upstream outage causes a failed or empty response
Very remote US locations (ocean areas, territories) may not have NWS grid coverage
