Very nice and thanks for sharing this! Out of curiosity where is this hosted? And how many paying subscribers do you have?

It's hosted on a dedicated server: a typical Apache, PHP + MySQL environment. Currently, there are around 50 premium users.

Are you using the wordPress REST API for all those transactions?

Classic AJAX calls, not the REST API.
