The ‘Rate limit exceeded’ error on GitHub generally appears when too many requests are sent within a short timeframe, exceeding GitHub’s API rate limit for unauthenticated users. By authenticating requests with a personal access token, you can increase the limit, especially for frequent or automated operations. If authenticated and still facing issues, reducing request frequency or caching responses can help avoid exceeding limits. Under *Settings > Developer settings > Personal access tokens*, generate an API token and include it in your headers (`Authorization: token YOUR_TOKEN`). Adopting efficient request handling and authenticated access typically resolves rate limit issues.
