Questions
FAQ
How do I use the Zhihu Topic Search (V3) API?
Send a POST request to https://api.sandbase.ai/v1/api/zhihu/web/topic-search-v3 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 Zhihu Topic Search (V3) 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 Zhihu Topic Search (V3) API accept?
Required: keyword (string). Optional: limit (string) and offset (string). The Parameters table and the Playground on this page list every field.
What does the Zhihu Topic Search (V3) 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 Zhihu developer account or API key?
No. Zhihu Topic Search (V3) 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 Zhihu API access separately.
