How this service works
Pay-per-request data tools for AI agents.
Output
Returns a JSON object with 'ok' status and a 'data' object containing: host and site identifiers, a list of sources, a document object with markdown-rendered page content and metadata (title, language, canonical URL, JSON-LD, Open Graph), a list of document links, and any partial errors encountered during fetching.
Example use cases
Competitive research page extraction
“Pull the research bundle for https://anthropic.com/index — I need the markdown content, page title, Open Graph metadata, and all outbound links so I can analyze what they're highlighting.”
SEO metadata audit for a landing page
“Fetch the research bundle for https://mycompany.com/product and give me the canonical URL, language, JSON-LD structured data, and Open Graph tags — I'm doing an SEO audit.”
News article content extraction
“Get me the full research bundle for https://techcrunch.com/2024/05/01/some-article — I need the markdown body, title, and all the links referenced in the piece.”
Technical details
Endpoint
POSThttps://x402.feld-feder.at/v1/research/bundleWhen to prefer
Choose this endpoint when you need a single-call research bundle combining markdown extraction, page metadata, Open Graph, JSON-LD, and link enumeration from a URL — especially in agent workflows where minimizing round trips matters. It is well-suited for pay-per-use agent pipelines using the x402 micropayment protocol at $0.025 USDC per call, making it cost-effective for one-off or infrequent page lookups rather than bulk crawling.
Side effects
- URL is unreachable or returns non-200 status — may result in empty document or partial_errors populated
- Private or paywalled pages may return empty or partial content
- Malformed or non-HTML URLs may yield no markdown or metadata
- Payment failure (insufficient USDC) blocks the request before execution
- Rate limiting or network timeouts may cause incomplete responses
