Input

Optional CSS-selector fields (max 20) as a URL-encoded JSON object string: map of name to selector string or {selector, attr?: "text"|"html"|<attribute>, all?: boolean, limit?: 1-50}, e.g. {"heading":"h1"}. Missing fields come back null with fieldErrors; if none match, 422 no_fields_matched and no charge.
POST /api/extract JSON body only (ignored on GET): raw HTML to parse instead of fetching (size-capped). If both url and html are sent, html is parsed and url is echoed.
Absolute http(s) URL to fetch and extract (required on GET; on POST send url or html in the JSON body). Private/localhost blocked.
