OpenRouter 推出 openrouter:web_search 搜索工具，只需指定一次 {"type": "openrouter:web_search"}，就能在 GPT-5.5、Claude、Kimi 等模型上以相同方式调用。此前各家供应商内置搜索工具使用不同 schema，切换模型时需要重写调用方式和结果解析逻辑，该工具用于消除这一差异。
正文
Every provider ships their own built-in search tool with a different schema. Normally, you switch models and have to rewrite how you invoke and parse results.
These tools fix that. Specify {"type": "openrouter:web_search"} once, and it works the same on GPT-5.5, Claude, Kimi, etc
