How this service works
Pay-per-call web and onchain utilities for AI agents (MPP + x402, USDC on Base).
Output
Returns a JSON object containing the page title, meta description, canonical URL, HTTP status code, Open Graph properties (og:title, og:image, og:description, etc.), Twitter card metadata, and any JSON-LD structured data arrays found on the page.
Example use cases
Link preview before sharing
“I'm about to share https://openai.com on social media — can you pull the Open Graph title, description, and image from that page so I know how it'll preview?”
SEO audit of a competitor page
“Grab all the metadata from https://stripe.com/payments — title, canonical URL, meta description, and any JSON-LD schema — I want to see how they've set up their SEO.”
Enrich a saved article URL
“I saved this article https://techcrunch.com/2024/01/01/ai-trends/ but only have the URL — can you fetch its title, description, and any structured data so I can add it to my reading list properly?”
Technical details
Endpoint
POSThttps://red-web-utils.agent-tools-x402.workers.dev/api/metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need lightweight, structured metadata extraction from a single URL without full page scraping — ideal for link enrichment, social preview generation, SEO auditing, or structured-data inspection. It is pay-per-call with micro-pricing ($0.001 USDC), making it cost-effective for on-demand agent workflows. Prefer this over full crawlers when you only need head-level metadata, not page body content.
Side effects
- URL is unreachable or returns a non-200 status — status field will reflect the HTTP error code
- Page has no Open Graph or JSON-LD metadata — those fields return empty objects or arrays
- JavaScript-rendered content not captured — only static HTML metadata is extracted
- Malformed or non-URL input causes a request failure
- Rate limiting or bot-blocking by the target site may result in empty or partial metadata
