Technical details
Endpoint
GEThttps://openweather-coral.vercel.app/weather/forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multi-day weather planning data with fine-grained 3-hour intervals and precipitation probability, rather than just current conditions. Prefer it over the current-weather sibling endpoint when the user's intent involves future forecasting, planning for upcoming days, or assessing rain likelihood over a period.
Side effects
- City name not found — returns error if city is misspelled or unrecognized
- Missing required query parameter — neither city nor lat/lon provided returns a bad request error
- Payment failure — 402 response if x402 payment is not completed
- Rate limit or server error — 5xx response if upstream OpenWeatherMap API is unavailable
- Ambiguous city name — may return forecast for wrong city if name is shared across regions
