Git.io API
Overview
Git.io is GitHub's own URL shortener service specifically designed for shortening GitHub URLs into compact git.io links. It requires no API key and works with a simple POST request, making it trivial to integrate. Note that Git.io only works with GitHub URLs (github.com domain), so it is not a general-purpose shortener.
Beginner Tip
Git.io only shortens URLs from the github.com domain: if you submit any other URL it will return an error. Use it in your GitHub-related tools or scripts to create cleaner links to repositories, commits, or pull requests.
