How this service works
Extract structured metadata from any web page: title, description, canonical URL, Open Graph and Twitter card tags, favicons, JSON-LD types, language and headings. Useful for link previews, content classification and SEO analysis.
Output
A structured JSON object containing the page's title, meta description, canonical URL, Open Graph properties (og:title, og:description, og:image, etc.), Twitter card tags, favicon URLs, JSON-LD @type values found on the page, the declared language, and an array of heading elements (h1-h6).
Example use cases
Link preview card generation
“Generate a link preview card for https://openai.com/blog/chatgpt — grab the title, description, and Open Graph image tag so I can display it in our app.”
SEO audit for competitor page
“Fetch the SEO metadata from https://www.shopify.com — I want to see the title, meta description, canonical URL, and heading structure to compare against our own site.”
Content type classification pipeline
“Check what kind of content is at https://schema.org/Article — pull the JSON-LD types and page language so I can classify it in our content pipeline.”
Technical details
Endpoint
GEThttps://agent-reader.agent-reader.workers.dev/metaWhen to prefer
Use this endpoint when you need lightweight, fast metadata extraction from a web page without full content scraping — ideal for link previews, SEO audits, social tag inspection, and JSON-LD type detection. Prefer it over full-page scrapers when you only need header-level metadata rather than body text.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty metadata
- Page uses JavaScript rendering and metadata is injected client-side — static fetch may miss dynamically loaded tags
- URL parameter missing or malformed — returns 400 bad request
- Target page blocks bots/crawlers — may return empty or partial metadata
- Very large pages may time out on the Cloudflare Worker
