Endpoint

GEThttps://openweather-coral.vercel.app/weather/forecast

When 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
