JsonLink
Powerful, free and super fast link scraper API for developers
About JsonLink
JsonLink is a developer API that extracts structured metadata from any URL, returning the title, description, image, favicon and site name as clean JSON. It powers rich link previews, URL unfurling and Open Graph extraction the same way Twitter, Facebook and WordPress see the web, and also offers endpoints for screenshots, image extraction and link harvesting.
Pros & Cons
Pros
- Dead-simple GET API with no SDK or complex setup required
- Returns clean, structured JSON for titles, descriptions, images and favicons
- Covers multiple use cases: metadata, screenshots, image and link extraction
- Generous free tier to prototype link-preview features
- Transparent flat monthly pricing with self-serve activation via Stripe
Cons
- Free plan is heavily limited (150 requests/month) and requires support verification for relief
- No usage-based or annual billing—only fixed monthly tiers
- Smaller, single-purpose service rather than a full content-intelligence platform
- Highest published tier caps at 500,000 requests/month, which may not suit very high-volume needs
