Missing JS files from eqneditor

Question

The below 2 files which were available for the eqneditor plugin of ckeditor are no longer accessible. Does anyone have a solution here? 

1. https://latex.codecogs.com/js/eq_config.js
2. https://latex.codecogs.com/js/eq_editor-lite-17.js

Answer 1

Looks like they've updated their API Documentation.
The new link is:

<script
    src="https://editor.codecogs.com/eqneditor.api.min.js"
    crossorigin="anonymous"
></script>

Here's a live example on jsFiddle.
And also their package on jsDelivr.com

Thank you Chun. But I'm not sure how to use the new links with ckeditor4. It'll be great if someone had the old js files.
