Questions
FAQ
How do I use the Open-Meteo Ensemble Forecast API?
Send a POST request to https://api.sandbase.ai/v1/api/open-meteo/ensemble with your SandBase API key in the Authorization header (Bearer) and the parameters as a JSON body. You can also try it in the Playground on this page without writing code.
How much does the Open-Meteo Ensemble Forecast API cost?
$0.0001 per call. Every organization gets 100 free calls per UTC day, shared across eligible SandBase APIs including this one; after that each call is billed at this price from your SandBase balance. There is no subscription.
What parameters does the Open-Meteo Ensemble Forecast API accept?
Required: latitude (string), longitude (string) and models (string). Optional: cell_selection (one of land, sea, nearest), daily (string), elevation (string), end_date (string), forecast_days (integer) and hourly (string) and 7 more. The Parameters table and the Playground on this page list every field.
What does the Open-Meteo Ensemble Forecast API return?
A JSON response returned in the same HTTP request (synchronous).
Do I need a Open-Meteo developer account or API key?
No. Open-Meteo Ensemble Forecast runs through SandBase, so one SandBase API key covers this endpoint and every other API and model in the catalog. You do not need to apply for Open-Meteo API access separately.
