GitHub's official URL shortener for GitHub-related links

Overview

Git.io is GitHub’s dedicated URL shortener for GitHub domains (repos, gists, blog posts). It uses a simple POST request to https://git.io with the 'url' parameter (optional 'code' for custom short paths). Responses include a JSON object (with Accept: application/json header) or Location header containing the shortened link. Ideal for sharing concise GitHub links in docs, social media, or presentations—no extra clutter. Non-GitHub URLs are unsupported, keeping it focused on GitHub ecosystem needs.
