How this service works
Fetch Open Graph / meta metadata (title, description, image, favicon, canonical URL) for a public URL.
Output
A JSON object containing the resolved page's title, description, OG image URL, favicon URL, canonical URL, final redirected URL, site name, and content type — all extracted from the page's Open Graph and meta tags.
Example use cases
Link card preview for chat app
“Grab the title, description, and preview image for https://www.nytimes.com/2024/01/15/technology/ai-future.html so I can render a link card in my messaging app.”
Enriching shared URLs in feed
“I have a list of URLs that users shared — can you pull the OG title, site name, favicon, and thumbnail image for https://github.com/vercel/next.js so I can show rich previews in the feed?”
Checking canonical URL and metadata
“What's the canonical URL, page title, and meta description for https://en.wikipedia.org/wiki/Artificial_intelligence? I want to make sure I'm referencing the right page.”
Technical details
Endpoint
GEThttps://link-preview-api-z4nf.onrender.com/previewWhen to prefer
Use this endpoint when you need to enrich a URL with its Open Graph and meta tag data for rendering link previews, building content cards, validating links, or populating structured records. Prefer this over a full scraping service when you only need preview-level metadata (title, description, image, favicon) and not the full page content.
Side effects
- URL is not publicly accessible (private, behind auth, or firewall) — returns error or empty fields
- Page has no Open Graph or meta tags — most fields will be null or empty
- URL redirects to an error page — final_url reflects redirect but metadata may be sparse
- Malformed or non-HTTP URL input — validation error
- Slow or unresponsive target server — timeout or incomplete response
