API

You can query cdnjs via our API as below

Without any query parameters it will return the name and main file URL of every library on cdnjs:

https://api.cdnjs.com/libraries

To search, use:

https://api.cdnjs.com/libraries?search=[query]

You can also "select" a certain library if you already know its name on CDNJS, e.g.

https://api.cdnjs.com/libraries/[name]

Without any query parameters it will return the whole meta data of the library, if you want to specify the info you want (recommended), use "fields" query:

https://api.cdnjs.com/libraries/jquery?fields=name,filename,version

All the usable fields is the same as the library's package.json on CDNJS (except auto-update config, we'll only return the auto-update type (currently npm or git)

API will return minified result by default, if you wanna have a human readable result, try output=human like so:

https://api.cdnjs.com/libraries?output=human

https://api.cdnjs.com/libraries?search=[query]&output;=human

If you would like more data, use the fields parameter which takes comma-separated values:

https://api.cdnjs.com/libraries?search=[query]&fields;=version,description

To get a list of all files for that library, use the assets field:

https://api.cdnjs.com/libraries?search=[query]&fields;=assets

Other fields available are: 

version
description
homepage
keywords
license
repository
autoupdate
author
assets

The API is served over Cloudflare with a hour expiry for requests.
