Link unfurling

Link unfurling without building the scraper yourself

Link unfurling is the process of taking a URL and turning it into a rich preview. OpenGraph.io handles metadata extraction, preview image detection, fallback logic, and normalized response data so your product can show useful previews without maintaining custom scraping infrastructure.

  • Convert any URL into a rich preview card with one API call
  • Enrich user-submitted links automatically at submission time
  • Show title, image, and domain context before users click
  • Avoid brittle custom metadata scrapers and edge-case handling
  • Support social-style previews natively inside your own product

How it works

From URL to preview data in seconds

01

Send a URL

Make a GET request to the API with your URL and API key as query parameters. That is the entire integration.

02

OpenGraph.io analyzes the page

The platform reads metadata, Open Graph tags, images, redirects, and fallback content from the live page.

03

Receive preview-ready data

Get back a clean JSON object — title, description, image, domain, favicon, and full OG and Twitter tag sets.

Developer experience

Simple enough to test. Reliable enough to build on.

Simple API access

Start with an API key and a GET request. No SDK required. Works in any language or framework.

Playground available

Test any URL in the API playground before writing a single line of integration code.

FAQ

A link preview API takes a URL and returns the data needed to create a rich preview card — including title, description, image, domain, and metadata — so your app can display context without the user needing to visit the page.
The free tool is for manually checking one URL. The Link Preview API is for generating previews automatically inside an application — it is designed to handle user-submitted URLs, bulk enrichment, and high-volume workflows.
Yes. Open Graph tags are one of the primary metadata sources. The API also reads Twitter Card metadata and falls back to standard HTML metadata (page title, meta description) when OG tags are absent or incomplete.
Link unfurling is the process of taking a URL and turning it into a rich preview with context like title, description, image, and domain — the same pattern used by Slack, iMessage, and LinkedIn when you paste a link.
Yes. This is one of the most common use cases. The API is built to handle unpredictable user-submitted URLs, including redirects, encoding edge cases, and pages with incomplete metadata.
Full documentation — including request parameters, response schema, code examples, and rate limits — is available in the API reference.
