Ya the e-cash wallet can be topped up via lightning. The merchant that processes the requests essentially does the same thing as PPQ, but this merchant takes e-cash notes rather than requiring that the customer has an API key (ie. account/identity).

I'm sure he would be happy to help you set it up..
ecash is something we've been looking at yes but we hadn't seen this implementation yet. Thanks.
Users are not required to have account/balance by their provider they could switch provider instantly without asking for refund..
when user sends a request an ecash token is created and added to the request, providers forward the request to an ai provider (like openai) get paid with the token provided and return change (if any) .. Basically the user has always a new identity
