Overview

The GitHub REST API gives you programmatic access to nearly everything on GitHub — repositories, issues, pull requests, commits, users, organizations, GitHub Actions, and more. Unauthenticated requests are allowed for public data but are limited to 60 requests per hour; authenticating with a personal access token raises the limit to 5,000 per hour. It is one of the most widely documented and used APIs in the developer ecosystem.

💡

Beginner Tip

Start with public endpoints that require no auth — like fetching repo info or listing releases. When you need more data or hit rate limits, create a Personal Access Token (PAT) at github.com > Settings > Developer settings > Personal access tokens. Pass it as Authorization: Bearer <token>. The API base URL is https://api.github.com.

}

Field Reference

full_name Owner and repository name in "owner/repo" format, e.g., "torvalds/linux".
description Short description of the repository as set by the owner.
stargazers_count Total number of users who have starred the repository.
forks_count Number of times this repository has been forked.
language Primary programming language detected in the repository.
open_issues_count Total number of open issues and pull requests combined.

Implementation Example 

// Get repository information
const url = "https://api.github.com/repos/github/docs";

const response = await fetch(url, {
  headers: {
    "Accept": "application/vnd.github+json",
    "Authorization": "Bearer YOUR_PERSONAL_ACCESS_TOKEN"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();

console.log(`Repository: ${data.full_name}`);
console.log(`Stars: ${data.stargazers_count}`);
console.log(`Forks: ${data.forks_count}`);
console.log(`Description: ${data.description}`);

Common Errors & Troubleshooting

403 Forbidden with rate limit message The 60 requests/hour unauthenticated limit has been exceeded
✓ Add Authorization: Bearer <your-pat> to your requests to raise the limit to 5,000/hour — create a token at github.com > Settings > Developer settings.
404 Not Found for a known repo The repository is private and your token does not have repo scope, or the owner/repo path is misspelled
✓ Check the capitalization of owner and repo name, and ensure your PAT has repo scope for private repositories.
Pagination stops early GitHub paginates results at 30 items by default and requires Link header navigation for subsequent pages
✓ Add ?per_page=100 to your request and follow the next URL from the Link response header until it is absent.
