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.
