Fetch a web page (Japanese-web-native) as low-impact, token-efficient Markdown. Built-in robots.txt compliance, rate limiting, and caching. mode: auto (default; quality score picks Markdown or screenshot) / markdown / outline (heading summary) / screenshot. Refetching a cached URL returns cache: unchanged, or diff (changed sections only), to save tokens. PDF URLs are handled automatically. mode: screenshot is the retry for pages whose Markdown came back poor; when the layout itself is the information or you need viewport/scale control, use the screenshot tool instead.

Enumerate URLs under a site or page without fetching each one. Tries sitemap.xml, then RSS/Atom feeds, then falls back to links found in the page itself; the response header reports which source was used (source:), the count:, and (truncated) when more than 200 links were cut. Each link is one line, - <title> — <url> (title omitted when unknown). filter narrows by substring or * glob against URL and link text; an empty result states whether the filter removed everything or the source had no links. Use it to find the right page before fetch. It does not return page content and does not follow more than the first 3 child sitemaps.

Render a page in a headless browser and return it as up to 10 tiled PNG images (1280px wide by default; fullPage: false returns only the first viewport). Pages taller than 10 tiles are cut off and the response says truncated: true. Use it when the layout or an image is the information (pricing tables, banners, visual QA) or when you need explicit viewport/scale control; scale: 0.5 roughly halves image tokens. For text content use fetch. Built-in robots.txt compliance, rate limiting, and caching.
