How this service works

Pay-per-request data tools for AI agents.

Output

A JSON object with ok:true and a data object containing: page title (string), language code (e.g. 'en'), an array of JSON-LD structured data objects, an array of Open Graph tag objects, and the canonical URL string.

Example use cases

SEO audit for a landing page

“Pull the metadata from https://mysite.com/landing — I want to see the page title, canonical URL, language, and any Open Graph or JSON-LD structured data it has.”

Social preview data for link sharing

“Grab the Open Graph metadata from this article URL https://techcrunch.com/2024/01/ai-trends so I can preview how it'll look when shared on social media.”

Structured data validation for a product page

“Check what JSON-LD structured data is published on https://shop.example.com/products/widget-x and tell me the canonical URL and page title too.”

Technical details

Endpoint

POSThttps://x402.feld-feder.at/v1/web/metadata?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need structured metadata (title, Open Graph, JSON-LD, canonical URL, language) from a specific URL without setting up your own scraping infrastructure. It is ideal for agents that need quick, pay-per-use web metadata extraction without API key management, making it suitable for low-frequency lookups where a subscription service would be overkill.

Side effects

Invalid or unreachable URL returns an error response
Pages behind authentication or paywalls may return incomplete metadata
Pages with no Open Graph or JSON-LD return empty arrays for those fields
Rate limiting or payment failure may block the request
Very slow or large pages may timeout
