Instant Link Metadata & Preview API

Titles, images, AI summaries & safe-link classification for any URL - at edge speed.

Paste a URL above and click "Run" to fetch metadata.

Why LinkMetadata?

LinkMetadata is perfect for anyone who needs to display rich link previews, summaries, or safe-link checks in their app or website. Common use cases include:

  • Chat & messaging apps — Instantly show a preview (title, image, description) when users share a link.
  • Social feeds & timelines — Enrich posts with safe, attractive link cards and flag unsafe content.
  • Content management & publishing — Auto-fetch metadata for referenced links in blogs, newsletters, or knowledge bases.

Features

  • Zero-config cache — canonicalises URLs and serves repeat requests from 13 ms global edge.
  • AI fallbacks — generates a clean title/description when sites forget their OG or metadata tags.
  • Fair credit model — quota counts only new links; cached hits are free.
  • No per-hour caps — burst up to 100 links/sec per IP by default.

Use the REST API or the Preview Component

Fetch rich metadata for any URL in a single request. Perfect for link previews, chat apps, and more.

Frequently Asked Questions

Can I use it for free?

Yes! The main endpoint doesn't require authentication and can be used by anyone. However some features, such NSFW filters, require a paid plan.

How fast is the API?

While it depends on a user's network quality, most requests are served in under 200ms. Uncached links are fetched and parsed in real time, usually within 1 second.

What happens if a site has no Open Graph tags?

We use alternative metadata if available, and we fallback to pre-generated domain-wide titles and descriptions. We try hard to get useful metadata—even from poorly tagged sites, but it may not be possible for all URLs.

Can I use this for commercial projects?

Yes! Our Pro and Enterprise plans are designed for production and commercial use, with SLAs and support available.
