How this service works
Fetch a page and extract title, description, OpenGraph/Twitter cards, canonical, and favicon.

Example use cases
Link preview card generation
“Fetch the metadata from https://openai.com/blog/chatgpt so I can render a nice link preview — I need the title, description, og:image, and favicon.”
SEO metadata audit
“Check what title, meta description, and canonical URL are set on https://example.com/landing-page — I want to make sure their SEO tags are populated correctly.”
Social share card inspection
“Pull the OpenGraph and Twitter card tags from https://github.com/vercel/next.js so I can see how it would appear when shared on social media.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/v1/url-metadataWhen to prefer
Use this endpoint when you need to extract standard webpage metadata (title, description, OG tags, Twitter cards, canonical, favicon) from any public URL without running a full browser. Ideal for building link previews, auditing SEO tags, or enriching content with page metadata. Prefer over general-purpose web scrapers when the specific goal is structured social/SEO metadata rather than full page content.
Side effects
- URL is unreachable or returns a non-200 status — metadata fields may be empty or error returned
- Page uses JavaScript rendering exclusively — statically served meta tags may be missing
- URL points to a non-HTML resource (PDF, image) — no HTML metadata available
- Page blocks crawlers via robots.txt or user-agent checks — fetch may fail or return partial content
- Malformed or invalid URL input — request rejected with validation error
