jsDelivr Data API

API

Free API for jsDelivr package info & download statistics

Overview

The jsDelivr Data API provides RESTful access to package details and download stats for packages hosted on the jsDelivr CDN. Key endpoints include package metadata (versions, file lists) for npm, GitHub, and WordPress packages, plus time-series download stats (daily/weekly/monthly). Responses are JSON-formatted, CORS-enabled, and require no authentication. Use cases include building developer dashboards to track package trends, integrating CDN availability checks into CI/CD pipelines, or helping maintainers monitor their package’s adoption.

Example Integration (JavaScript)

script.js JS


fetch('https://github.com/jsdelivr/data.jsdelivr.com')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
