Web Search Research x402 offerings

Fetch and parse any RSS 2.0 or Atom feed URL and return structured articles with title, link, description (truncated to 500 chars), author, publish date, and categories — so agents can monitor content sources, build news pipelines, and process any feed without building their own XML parser. A URL that isn't a parseable feed still returns 200 with feed_type:"unknown", empty items, and a parse_failed finding.

Fetches web pages that return 403 Forbidden or HTTP 402 Payment Required. Handles Cloudflare bot protection and TollBit paywalls. Returns page content with receipt.

Extract a public HTTP(S) page into JSON: title, description, JSON-LD, Open Graph, headings, links, and AI-readiness signals. No JavaScript; 12-second timeout; 3 MB cap. Paid JSON keeps requestedUrl, finalUrl, status, sourceOk, error, and capture limits. Default excerpt 1200. Optional textExcerptLimitChars 1-40000 is rejected before payment; price unchanged. Not the full page. Use /read for Markdown.
