Technical details
Endpoint
GEThttps://payai.agentstools.dev/forecast?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, government-sourced US weather forecasts with both Celsius and Fahrenheit temperatures, precipitation probabilities, and wind data — especially when accuracy and public-domain provenance matter. Prefer this over third-party weather APIs when working with US addresses or coordinates and when commercial use is required without licensing concerns.
Side effects
- Non-US coordinates or address provided — NWS only covers the United States, returns error or no data
- Invalid or unresolvable address string — geocoding fails, no forecast returned
- lat/lon out of valid range (lat outside -90 to 90, lon outside -180 to 180) — validation error
- days parameter outside 1–7 range — schema validation error
- NWS API upstream outage — service temporarily unavailable
- Coordinates fall in water or outside NWS grid coverage — no forecast grid available
