Im an open agents subscriber. Didnt know about fewsats, looks cool, but requires email to login AFAICT.

I also am looking for something more user friendly than DVMs.

I have may own agent framework in any case called #sandymount and I've tried to add DVMs many times, but yet to get that over the line. I think it will be easier to do next year.

I think with nostr is that you simply need a business to add nostr. Hopefully with a professional relay. No one seems to have done that yet. Which is odd, after all this time.
