Questions

FAQ

How do I use the Lemon8 Topic Information API?

Send a POST request to https://api.sandbase.ai/v1/api/lemon8/app/topic-info 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 Lemon8 Topic Information API cost?

$0.0015 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 Lemon8 Topic Information API accept?

Required: forum_id (string). The Parameters table and the Playground on this page list every field.

What does the Lemon8 Topic Information API return?

A JSON response returned in the same HTTP request (synchronous). The README on this page includes a sample response.

Do I need a Lemon8 developer account or API key?

No. Lemon8 Topic Information 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 Lemon8 API access separately.
