Zhihu Websearch

English | 简体中文

Zhihu Web Search (Global Search) as an OpenCode websearch provider.

Zhihu Global Search is a high-trust search service for AI applications, combining high-quality Zhihu content with authoritative web sources to deliver real-time, structured, and traceable results. It offers high-quality, highly relevant results for Chinese-language queries.

Requirements

• OpenCode v2
• A Zhihu Open Platform account with an Access Secret: https://developer.zhihu.com/profile

Install

opencode plugin add opencode-zhihu-websearch

Or add it to opencode.jsonc:

{
  "$schema": "https://opencode.ai/config.json",
  "plugins": ["opencode-zhihu-websearch"],
  "websearch": { "provider": "zhihu" },
}

Without websearch.provider, OpenCode asks you to pick a provider the first time you search.

Credentials

Run /connect and pick Zhihu, or set ZHIHU_ACCESS_SECRET before starting OpenCode. A stored credential takes priority over the environment variable.

Options

Plugin options are optional:

{
  "plugins": [
    {
      "package": "opencode-zhihu-websearch",
      "options": { "count": 8, "searchDB": "realtime" },
    },
  ],
}

Option	Values	Default	Description
count	1-20	10	Number of results
searchDB	all, realtime, static	all	Search index
filter	Filter expression	none	Filter results by site or publish time
endpoint	URL	Zhihu Global Search API	Override the search endpoint

filter uses Zhihu's filter syntax: host supports == and != with a double-quoted value, publish_time (Unix seconds) supports ==, !=, >, >=, < and <=, and conditions combine with uppercase AND/OR and parentheses. Filtering on zhihu.com itself is not supported. Escape the quotes in JSON:

"options": { "filter": "host!=\"example.com\" AND publish_time>=1735689600" }

Development

bun install
bun run typecheck
bun run test

# optional: hits the real API, needs ZHIHU_ACCESS_SECRET
LIVE=1 bun run test:live
