Extract markdown or structured content from a URL using the Diffbot Extract API — a live fetch and parse of the page, seconds per call. Try `/diffbot-web-search` with `url:<URL>` first: it reads Diffbot's already-extracted copy from the Web Index in ~300ms and answers most page questions outright. Use this skill when that lookup misses (URL not indexed) or when you need the complete document rather than the relevant chunks. Triggers on: extract URL, fetch page, parse webpage, get content from URL, extract article, extract structured data, full page text, whole article.
