How this service works
Agent-ready x402 APIs for AI video production, audio localization, web research, document extraction, data analysis, and structured JSON transformation.
Output
Returns a JSON object with status, request_id, and a result object containing extracted metadata fields such as page title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), Twitter card tags, canonical URL, keywords, author, favicon URL, schema.org structured data, and any other HTML head metadata. May include a usage object and warnings array for partial extraction cases.
Example use cases
Link preview card generation
“I'm building a link preview feature — can you grab the title, description, and Open Graph image URL from https://www.theverge.com/2024/3/10/apple-vision-pro-review so I can generate a preview card?”
SEO metadata audit for a competitor page
“Can you extract all the metadata from https://stripe.com/payments — I want to see their page title, meta description, canonical URL, and any schema.org markup they're using?”
Article metadata for content aggregation
“Pull the structured metadata from https://medium.com/@johndoe/building-ai-agents-2024 — I need the author, publish date, keywords, and description to index it in my content library.”
Technical details
Endpoint
POSThttps://api.x402cloud.space/api/v1/web-metadata-extractorWhen to prefer
Choose this endpoint when you need fast, structured extraction of HTML metadata (titles, Open Graph, schema.org, canonical URLs) from a web page without needing to parse or process the full page body. It is ideal for link preview generation, SEO audits, content indexing, and metadata enrichment pipelines. Prefer this over a full web scraper when you only need head-level metadata and want a clean JSON response at low cost ($0.01 USDC per call via x402 micropayment).
Side effects
- URL is unreachable or returns a non-200 status — result may be empty or partial
- Page uses heavy JavaScript rendering and metadata is not in static HTML — dynamic content may not be extracted
- URL is behind a paywall or authentication — returns empty or minimal metadata
- Malformed or missing input URL — returns validation error
- Rate limiting or bot protection on target site — request may fail or return blocked page metadata
- Network timeout on slow-loading pages — may return partial results with warnings
