Questions
FAQ
How do I use the Bilibili Video Captions API?
Send a POST request to https://api.sandbase.ai/v1/api/bilibili/video-caption 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 Bilibili Video Captions 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 Bilibili Video Captions API accept?
Required: bvid (string), aid (string) and cid (string). The Parameters table and the Playground on this page list every field.
What does the Bilibili Video Captions API return?
A JSON response returned in the same HTTP request (synchronous).
Do I need a Bilibili developer account or API key?
No. Bilibili Video Captions 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 Bilibili API access separately.
