Extract article to Markdown

Added value: +{
+  "default": true,
+  "description": "Strip browser chrome (scrollbars, consent/cookie banners, fixed nav and overlays) before conversion. These elements poison Readability density scoring and clutter fragment output.",
+  "type": "boolean"
+}

Added value: +"Markdown code-block style: 'fenced' (triple backticks) or 'indented' (four-space)."

Added value: +"Readability scoring aggressiveness: 'balanced' (default), 'aggressive', or 'conservative'. Maps to Readability's scorer knobs."

Added value: +"Returned payload format: 'markdown' (default), 'html', 'text', or 'json' (emits {metadata, content, diagnostics})."

Added value: +"Enable GitHub-Flavored Markdown: tables, strikethrough, and task lists."

Added value: +"Markdown heading style: 'atx' (#) or 'setext' (underlining with = / -)."

Added value: +"Already-rendered HTML (post-JavaScript), e.g. the result of document.documentElement.outerHTML from a browser/devtools capture. This is the ONLY input the server reads; it makes no outbound requests."

Added value: +"Image handling: 'keep' (inline ![alt](url)), 'drop', 'src-only' (bare URL text), or 'reference' (link-reference style)."

Added value: +"Retain all CSS classes on extracted nodes. Defaults false, which strips non-language classes."

Added value: +"Truncate markdown/text output at a block boundary; never splits a fenced code block. Ignored for html/json formats."

Added value: +"Hard cap on elements parsed (Readability maxElemsToParse). Safety/perf guard for very large documents."

Added value: +"Prepend a metadata block to the markdown/text payload: 'none' (default), 'yaml', or 'json'."

Added value: +"Minimum article character length below which extraction falls back to the selector cascade (Readability charThreshold)."

Added value: +"Escape hatch: a record spread verbatim into the Readability options. Unstable and unvalidated; overrides the extraction/keepClasses/maxNodes/minArticleLength knobs."

Added value: +"Run DOMPurify over the extracted/fragment HTML before conversion (strips scripts, event handlers, and iframes)."

Added value: +"Scope the extracted/converted content by CSS selector before processing."

Added value: +"CSS selectors for boilerplate to remove before extraction (e.g. [\"nav\", \"footer\", \"[role=banner]\"])."

Added value: +"CSS selector restricting extraction to a matching subtree (e.g. \"main\", \"article\", \".post\"). The first match replaces the document body before processing."

Added value: +"Origin URL for absolutizing relative links and images. NEVER fetched — origin context only."

Added value: +"Reading speed (words per minute) used to compute metadata.readingTimeMin."

Added value: +"The human/LLM-readable payload — Markdown/html/text, or the serialized JSON when format=json."

Added value: +"Pipeline telemetry describing what was extracted, sanitized, and removed."

Added value: +"DOM root extraction came from: \"readability\" (main path), a fallback selector (e.g. \"article\", \"main\"), or \"fragment\" for html_to_markdown."

Added value: +"True if Readability parse failed and a selector cascade salvaged content. Always true for html_to_markdown."

Added value: +"Count of lazy/placeholder images resolved to their real src before conversion."

Added value: +"Readability isProbablyReaderable verdict on the document (extract main path only)."

Added value: +"Net element count removed across the whole pipeline (delta vs. the parsed document)."

Added value: +"Counts of nodes removed by DOMPurify sanitization."

Added value: +"<iframe> elements removed by sanitization."

Added value: +"<script> and event-handler nodes removed by sanitization."

Added value: +"True if the payload was truncated by maxChars."

Added value: +"Resolved article metadata. Each field is the first non-empty value across a priority cascade."

Added value: +"Article author(s), resolved from JSON-LD, OpenGraph, <meta>, or Readability."

Added value: +"Short article summary produced by Readability."

Added value: +"Detected document language."

Added value: +"Publication timestamp resolved from JSON-LD, <meta>, or <time> elements."

Added value: +"Estimated reading time in minutes, derived from wordCount and wordsPerMinute."

Added value: +"Publishing site name, resolved from OpenGraph or <meta>."

Added value: +"Article title, resolved by priority cascade (JSON-LD → OpenGraph → Twitter → <meta> → Readability → <title>)."
