Questions
FAQ
How do I use the Weibo Real-Time Hot Search API?
Send a POST request to https://api.sandbase.ai/v1/api/weibo/web-v2/hot-search 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 Weibo Real-Time Hot Search 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 Weibo Real-Time Hot Search API accept?
Weibo Real-Time Hot Search takes no input parameters; send an empty JSON body.
What does the Weibo Real-Time Hot Search 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 Weibo developer account or API key?
No. Weibo Real-Time Hot Search 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 Weibo API access separately.
