GitHub Contribution Chart Generator API
Overview
The GitHub Contribution Chart Generator API creates a visual representation of any GitHub user's contribution activity over the past year. No API key is required — simply provide a GitHub username and embed the generated image URL directly in a README or webpage. It is a great beginner project for learning how to work with image-generating APIs.
Beginner Tip
You can embed the chart directly in a GitHub README using Markdown: . No code needed — just swap in your username and paste the link.
