Questions

FAQ

How do I use the Weather Underground Monthly Observations API?

Send a POST request to https://api.sandbase.ai/v1/api/weather-underground/monthly-observations 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 Weather Underground Monthly Observations API cost?

$0.01 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 Weather Underground Monthly Observations API accept?

Required: year (integer), month (integer) and station_id (string). Optional: country_code (string). The Parameters table and the Playground on this page list every field.

What does the Weather Underground Monthly Observations API return?

A JSON result. This endpoint runs asynchronously, so the response tells you how to fetch the finished result.

Do I need a Weather Underground developer account or API key?

No. Weather Underground Monthly Observations 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 Weather Underground API access separately.
