Wordpress AMP. How to validate a link?

Question

Accelerated Mobile Pages

Hello, we are developing a website on AMP with a custom template. We also use critical css in our work in order to pull out styles only for a specific page. I'm having problems displaying the page and I would like to know if there is any function for this plugin that I can call, pass the url to it and get information about whether it is valid or not.
I combed through the documentation and didn't find anything. I also dug into the source code, did not see it. Maybe someone faced such a situation?

Greetings.
I don’t know if I understood the question exactly, but in general, the validity of an AMP page is checked like this .
