Read a web page as clean Markdown⟨5 unchanged words⟩ selected sections from a public URL or raw HTML as clean Markdown, with navigation, scripts and page chrome removed. Use it instead of a raw fetch when a task needs the text of documentation, an article, an RFC or another reference page: in a five-site benchmark the Markdown was 62% fewer estimated tokens than the HTML. Call the free clean_extract_outline first on a long page, then pass only the section ids you need. A call is charged only when it returns ⟨7 unchanged words⟩ calls are free, total, then USD 0.05.Use the free clean_extract_outline first.Uncharged failures name upstream_timeout, upstream_http_error, bot_challenge, ⟨15 unchanged words⟩

Changed the definition of "clean_extract"
Extract clean, token-dense markdown fromConvert a public URL or raw HTMLstring.into token-dense markdown. Every response reportsextraction_content_ratio_band and the measurements inextraction_quality: the source-authored markdown bytes in the delivered output as a fraction of the source payload bytes,banded zero, below_threshold or at_or_above_threshold. That is a size measurement, not a statement that the page's content survived: a lightly marked-up page whose one load-bearing line was dropped scores a high band, and a faithful extraction of a navigation-heavy page scores a low one. The band is a triage hint, not a completeness guarantee. The first 3 calls are free, total, with no signup and no claim header; the allowance does not reset. Every later extraction costs USD 0.05 viaincludingx402.extraction_content_ratio_band.
