Audit Open Graph Tags Across Pages
Check whether pages are correctly set up for social sharing by auditing their Open Graph metadata.
Fetch Rich Metadata from URLs
Pull the title, description, thumbnail image, and Open Graph data from any public URL.
Tool
When you share a link in a messaging app, the preview that appears — the title, description, and thumbnail image — comes from Open Graph metadata embedded in the page. Accessing that data programmatically without visiting the page, parsing the HTML, and extracting the right tags is a non-trivial amount of work for a task that should be simple.
The preview_url skill fetches a URL and returns its structured metadata: page title, meta description, Open Graph title and description, thumbnail image URL, site name, and content type. You get the full preview data in one call.
Developers building link-sharing features, content teams curating external resources, and researchers building reference databases all use this to pull clean metadata from URLs without writing a custom scraper for every site format.
