How this service works
Machine-readable settlement service
Output
Returns a structured JSON object containing the page's metadata fields such as title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), canonical URL, and other available head-tag data extracted from the target web page.
Example use cases
Link preview card generation
“I need to generate a link preview card for this article — grab the page title, description, and OG image from https://techcrunch.com/2024/01/ai-trends so I can display it in my app.”
SEO metadata audit
“Pull all the meta tags and Open Graph data from our homepage at https://mycompany.com so I can check what title, description, and image show up when people share it on social media.”
Content aggregator enrichment
“I'm building a reading list and need the structured metadata — title, author, description — from this blog post at https://blog.example.com/post/123 to display alongside the link.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/mini/web.page-meta--page-metadataWhen to prefer
Choose this endpoint when you need lightweight, structured metadata extraction from a public web page URL — particularly for building link previews, enriching content feeds, or auditing SEO tags — and you want a pay-per-call model via x402 rather than managing a scraping infrastructure subscription. It is best suited for static or server-rendered pages where head metadata is present in the HTML.
Side effects
- Target URL is unreachable or returns a non-200 status — empty or error response returned
- Page has no meta tags — result object may be sparse or empty
- JavaScript-rendered pages may not have metadata extracted correctly if SSR is not available
- Payment not processed (x402 protocol failure) — request rejected before execution
- Malformed or missing input URL — validation error returned
