Zhihu (知乎) is China’s question-and-answer network — the place for long, reasoned answers from practitioners, and a prime source for research on how Chinese professionals think about a topic. It has no public API and gates most pages behind a login. Through AgentKey your agent reads public Zhihu data the same way it reads everything else — find_tools, describe_tool, execute_tool — with more than one provider behind the scenes, so one route failing does not stop the task.

How to use it

Pass the request in plain language and let the router pick the tool:
Both English and Chinese phrasing work, and the platform’s usual English and Chinese names all land here. Always describe_tool before executing — parameters and per-call costs differ between providers.
Building with code? The same capability is available as fixed-contract Scenario Methods with automatic provider failover: social.zhihu.post.search, social.zhihu.post.get, social.zhihu.topic.search, social.zhihu.user.get, social.zhihu.user.posts, social.zhihu.user.search, social.zhihu.trending.

FAQ

No. AgentKey holds the upstream access; your agent only needs your AgentKey subscription.
Salt titles can be searched like other content types. Whether a given title’s body is returned depends on what Zhihu serves publicly for it; paywalled text is not unlocked.
Every call goes to Zhihu at request time; the hot list, answers and comments reflect what Zhihu returns at that moment.
