Post Purchase Question

I would like to know if there a script I can place in a non-WordPress directory on WordPress site?

For example, Silm Stat is a plugin, and I can use this code to monitor my non-WordPress directory that has traditional html website (think old-school purest with lots of json):

<!-- START -->
<script type="text/javascript">
/* <![CDATA[ */
var SlimStatParams = { ajaxurl: "https://test.com/panel/admin-ajax.php" };
/* ]]> */
</script>
<script type="text/javascript" src="https://test.com/test/js/wp-slimstat.min.js"></script>
<!-- END -->

Does your plugin have a piece of code like that I could use?

Thanks!
