Link Preview API.

Exabase Link Preview API

Transform any URL into rich, structured metadata with a single API call. The Exabase Link Preview API extracts titles, descriptions, images, favicons, and complete Open Graph data from any web page—even those rendered with JavaScript—delivering production-ready JSON responses for building engaging link cards and content previews.

Product Highlights

• JavaScript Rendering: Automatically renders JavaScript-heavy sites including React and Next.js applications, eliminating empty responses from dynamic pages without requiring headless browsers or Puppeteer on your end.
• Generous Free Tier: Process up to 20,000 link previews per month completely free, with simple pay-as-you-go pricing beyond that threshold for serious scale.
• Comprehensive Metadata Extraction: Returns title, description, preview image URL, canonical URL, locale, site name, plus full image and favicon details including dimensions, file size, and MIME type.
• Built-in Content Safety: Optional malware and adult content filtering with the block_content parameter, returning a 424 error for unsafe URLs before they reach your users.
• Intelligent Caching & Reliability: Popular URLs return instantly from cache with 24-hour automatic caching, 99.9% uptime, and 95%+ success rate across the web including sites that block basic scrapers.

Use Cases

• Chat and Messaging Apps: Render rich link cards when users paste URLs, matching the experience users expect from Slack, Discord, WhatsApp, and iMessage.
• Content Management Systems: Enable editors to paste any URL and auto-generate preview cards with title, image, and description without manual data entry or broken embeds.

• Social Media Scheduling Tools: Show users exactly how links will render on Twitter, LinkedIn, and Facebook before publishing, with image dimension validation to catch incorrect aspect ratios.
• Email Newsletter Platforms: Generate HTML link preview cards for curated link roundups by pulling structured metadata and rendering into email-safe templates.

Developers and product teams building AI agents, chat applications, content platforms, and social tools who need reliable, scalable URL metadata extraction without maintaining complex scraping infrastructure. Ideal for teams prioritizing privacy, security, and rapid integration over building and maintaining their own headless browser solutions.
