Browser engine for AI agents: fetch JS-rendered and Cloudflare-protected pages as clean markdown, run 5-engine aggregated web search (Baidu, Bing, Sogou, WeChat, Google), take screenshots as visual input, extract structured data from SPAs, and drive multi-step interactions (click, type, fill forms, login, paginate) through indexed sessions. One HTTP API from a single Rust binary — no Chromium. Use when the agent needs to read a web page, scrape or extract content from a URL, search the web, screenshot a page, log in or fill a form, or click through interactive content. Triggers include user requests to "read this page", "open this link", "what does this site say", "search the web", "take a screenshot", "scrape this page", "download this file / this zip / this pdf", "log in and do X", "fill out this form", "click through this", "bypass Cloudflare", and Chinese equivalents (打开这个网页/看看这个网站/搜一下/ 截图/登录/填表/翻页). Trigger words: scrape, fetch, read this page, open this link, web search, look up, screenshot, headless browser, browser automation, Cloudflare bypass, CAPTCHA, login, fill form, paginate, 抓取/读取/搜索/截图/登录/填表/翻页/下载.
