I did not get it how it could be used for a _static blog_.
>…the paywall fetches the content behind the scenes, and since our response is JSON rather than HTML it has nothing to render in place, so it navigates to an in-memory object URL created from the response. The protocol itself is pay per use, so every time you hit an API - you will be charged.
So it can't be used to 'unlock' a paid article forever? You can only read it once, and if you closed the tab, you need to pay again?
