Link Preview API

What it does

Link Preview API is a free, production-ready API that extracts Open Graph metadata from any URL. It returns structured JSON with title, description, og:image, favicon, image dimensions, site name, and more. The API handles JavaScript-rendered pages, includes built-in image validation, and offers dedicated support for popular websites like YouTube, Amazon, Twitter, Airbnb, SoundCloud, NYT, Vimeo, and Giphy. It also provides anti-bot evasion, caching, and content filtering for malware or adult content. Usage is free up to 20,000 link previews per month, with a nominal charge beyond that.

Who it is for

This API is designed for developers building applications that need to display rich link previews. Use cases include chat and messaging apps (like Slack or Discord), CMS link cards, bookmark managers, social media scheduling tools, email newsletters, content aggregators, SEO audit tools, browser extensions, and affiliate or comparison sites. It is also suitable for AI agents and knowledge bases that need to enrich stored URLs with metadata.

Why it matters

Rendering link previews manually requires maintaining a headless browser, handling timeouts, retries, caching, and rate limiting. Link Preview API simplifies this to a single GET request. It offers JavaScript rendering, which many competitors lack, ensuring accurate previews for modern web apps. The free tier (20,000 previews/month) is generous compared to alternatives like OpenGraph.io, which charges $15/mo for 1,000 requests. The API also includes image validation, malware blocking, and CORS support, reducing development overhead.

Launch signal

The product is currently featured on Product Hunt and is part of Exabase, a broader platform offering memory, file storage, search, and extraction APIs for AI agents. The website emphasizes that over 1,000,000 link previews are processed per month, indicating existing traction. The API is available immediately with a free sign-up and no credit card required.

Brand and naming

The name 'Link Preview API' is highly descriptive and functional, clearly communicating the product's core value. However, it lacks distinctiveness and memorability, as it's a generic term that could apply to many similar services. The domain 'linkpreviewapi.com' is likely taken, and the name doesn't differentiate from competitors. Positioning is clear: a free, scalable API for extracting Open Graph data. The tagline reinforces this, but the name itself doesn't create a strong brand identity.
