How this service works
Get structured metadata for any public web page in one call: title, meta description, canonical URL, Open Graph and Twitter card tags, favicons, JSON-LD schema types, language and the heading outline. Use it to build link previews and social cards, classify or dedupe URLs, and run SEO and AI-readability audits - far cheaper than fetching and parsing the whole page.
Output
Returns a structured JSON object containing the page title, meta description, canonical URL, Open Graph tags (og:title, og:description, og:image, og:type, etc.), Twitter card tags, favicon URLs, JSON-LD schema types found on the page, detected language, and an array of headings (H1–H6).
Example use cases
Link preview card generation
“I need to generate a link preview for https://techcrunch.com/2024/01/15/openai-news — grab the title, description, Open Graph image, and canonical URL so I can display it nicely in the app.”
SEO metadata audit
“Can you check the SEO metadata on https://mystore.com/products/blue-widget? I want to see the title tag, meta description, canonical URL, and whether it has proper Open Graph tags set.”
Content classification by JSON-LD type
“Fetch the metadata from https://nytimes.com/2024/03/01/science/climate.html and tell me what JSON-LD types and structured data it has so I can classify what kind of content it is.”
Technical details
Endpoint
GEThttps://agentreader.dev/metaWhen to prefer
Choose this endpoint when you need lightweight, fast metadata extraction from a URL without needing the full page body — ideal for link previews, SEO audits, content classification, and Open Graph / Twitter card inspection. Prefer this over a full-page scraper or article extractor when you only need head-level metadata, structured data types, and headings rather than the main article content.
Side effects
- URL is not reachable or returns a non-200 status — endpoint may return an error or empty fields
- Page blocks crawlers via robots.txt or bot detection — metadata may be partial or missing
- JavaScript-rendered pages where meta tags are injected client-side may not be captured
- Malformed or relative URLs passed as input will fail the required absolute URL validation
- Pages with no meta tags return mostly empty fields but do not error
