Overview

PageCDN exposes a public API to query its CDN library catalog — including JavaScript packages, CSS frameworks, and web fonts — so developers can look up available versions and generate optimized CDN URLs programmatically. It is particularly useful for build tools or dashboards that need to resolve the latest stable version of a library without scraping npm or GitHub. An API key is required but is freely available on registration.

💡

Beginner Tip

Sign up at pagecdn.com to get a free API key, then include it as the api_key query parameter in every request. Start by calling the library-search endpoint to confirm your key works before building anything more complex. The response includes pre-built CDN URLs you can drop directly into HTML script or link tags.

const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

401 Unauthorized Missing or invalid api_key parameter in the request
✓ Register at pagecdn.com, copy your API key from the dashboard, and append ?api_key=YOUR_KEY to every request
Empty results array Library name typo or querying a package that is not indexed on PageCDN
✓ Try a shorter, exact package name (e.g., "jquery" not "jQuery.min") and check the PageCDN library list for supported packages
Rate limit exceeded (429) Too many requests in a short period on the free tier
✓ Add a short delay between bulk requests or upgrade to a paid plan for higher rate limits
