Overview

jsDelivr's Data API provides programmatic access to package metadata and download statistics for npm, GitHub, and WordPress packages hosted on the jsDelivr CDN. It requires no authentication and is useful for building dashboards, tracking package popularity, or researching CDN usage trends. All responses are returned as JSON with no rate limits for reasonable usage.

💡

Beginner Tip

No API key is needed. Just construct the URL with the package name and optional version to get stats or file listings. Use the /stats/packages endpoint to compare download volumes across different packages.

Common Errors & Troubleshooting

404 Not Found The package name or version does not exist on jsDelivr
✓ Double-check the package name spelling and ensure it is available on jsDelivr; check https://www.jsdelivr.com/package/npm/PACKAGE_NAME in a browser first
Empty hits array in stats response No data available for the requested date range
✓ jsDelivr stats have a delay; try a date range from a few days ago or use the /stats/packages endpoint for aggregated data
Incorrect package type used Using /npm/ path for a GitHub-hosted package or vice versa
✓ Use /npm/ for npm packages, /gh/ for GitHub repos (format: /gh/user/repo), and /wp/ for WordPress plugins
