How this service works

Output
Returns a structured object containing web page metadata such as the page title, meta description, Open Graph tags (og:title, og:description, og:image), canonical URL, and other head-level meta properties parsed from the target webpage.
Example use cases
Link preview card generation
“Fetch the title, description, and Open Graph image URL from https://techcrunch.com/2024/01/15/openai-new-model so I can build a preview card for it.”
SEO audit data collection
“Pull the meta title and meta description from https://mycompany.com/about so I can check how the page appears in search results.”
Content aggregator enrichment
“Get the structured metadata from https://medium.com/some-article — I need the title, author if available, and description to enrich my RSS feed entries.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/mini/web.page-meta--metaWhen to prefer
Choose this endpoint when you need a lightweight, paid-per-call web page metadata extraction without setting up your own scraper infrastructure. It is well-suited for link preview generation, SEO auditing, or content enrichment pipelines where you need title/description/OG tags from arbitrary URLs. Prefer it over general-purpose scraping endpoints when you specifically need structured head metadata rather than full page content.
Side effects
- Target URL is unreachable or returns a non-200 status — empty or error response returned
- Target page has no meta tags — response object may be sparse or empty
- Invalid or malformed URL input — request fails with validation error
- Page blocks server-side crawlers — metadata extraction returns partial or no results
- Payment not processed — 402 response returned before data is delivered
