How to Subdomain Endpoints for AMP? (wordpress)

Hello guys,

i need a plugin for Subdomain Endpoints for AMP, for free.

it should look like this;
sub-normaldomain-net.cdn.ampproject.org/c/s/sub.normaldomain.net/amp/

it normally looks like this;
https://www.google.com/amp/s/normaldomain.net/

Ask a mod to move this to the requests section. Might have better luck there.
