How to check if a router is REST API capable?

[PeterFranca]

Hi All, 

Does anyone knows how to check if a router is REST API capable? 

I have a few ISR 4000 series router and I can't find the documentation that shows how to enable the REST API in the router. 

I am wondering if the box is able to run API or not.

The "sh license feature" command does not show any API information at all.  

Thanks for the help.

 - Guess easiest method would be to check/test one of the resources mentioned below :

 (check paragraph URI and resources)
