Every item also has platform, id, ref, approx and type; the response around the items is the same on every call. Response format
Zhihu Detail API: paging and billing.
5 calls per second per key, 20 after a purchase; going over is not charged. Rate limits
A failed call costs 0 credits and is never retried on its own. Error codes
“Last tested” above is the last day a real call of this interface succeeded. Each call reads from the platform, and fetched_at in the answer is when it was read. The same request sent again with the same key within 5 minutes is a replay (replayed: true): 0 credits, and the answer as first read.
Once connected over MCP, these questions use the Zhihu Detail API.

How to connectUse the SocialToAI MCP server (https://mcp.socialtoai.com/mcp) for this: Read this Zhihu answer: 2430879961Call the detail tool with {"platform":"zhihu","id":"2430879961"}. Needed: id, url.For several, call it once for each: 2 credits each.Before you start, work out how many credits it will take in all and ask me; call it only after I agree.What usually comes next, with the ref or username it returns: comments (Comments).If SocialToAI is not connected yet, tell me how to connect it; never ask me to paste a key into the chat.Answer with a link to every item you used, and tell me how many credits it cost.Paste it into a chat once SocialToAI is connected over MCP. There is no key in it: Claude and ChatGPT sign in, other clients send a key in a header.
