How this service works
Machine-readable settlement service
Output
Returns a JSON object containing page metadata extracted from the target URL, typically including fields such as page title, meta description, Open Graph properties (og:title, og:description, og:image, og:url), canonical URL, and potentially other head-tag metadata available on the page.
Example use cases
Link preview card generation
“Pull the title, description, and OG image for https://techcrunch.com/2024/05/01/openai-news so I can display a rich link preview card in my app.”
SEO audit metadata check
“Fetch the page metadata for https://myshop.com/products/sneakers and tell me what the title tag and meta description currently say.”
Content pipeline URL enrichment
“I have this article URL — https://blog.example.com/post/ai-agents — can you grab its structured page metadata so I can tag and categorize it in my content database?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/mini/web.page-meta--url-metadataWhen to prefer
Use this endpoint when you need lightweight, structured page metadata (title, description, OG tags) from a URL without needing full page content or DOM traversal. Ideal for link preview generation, content enrichment pipelines, or SEO audits where a fast, cheap per-call cost ($0.002 USDC) is acceptable and you want a simple POST-based API with micro-payment settlement via x402.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty metadata
- Target page blocks crawlers via robots.txt or JS rendering requirements — metadata may be incomplete
- Malformed or missing input URL — likely returns a validation error
- Payment settlement failure via x402 — request not processed
- Paywalled or login-gated pages — metadata may be minimal
