yes, paying for services is a big interest of mine which is why you'll find the term NIP-42 repeatedly in my notes, because almost no clients actually implement it properly and fully

i'm working on a relay that properly supports it but actually testing this feature is currently nearly impossible... the client implementations are very very patchy

getting more clients to fully support NIP-42 is critical to enabling pay-per-use and subscription models and modular storage back ends and search engine systems as they call them DVMs

until this support is widespread we are all depending on donations and grants and investors paying devs to build

there is a problem in the nostr dev culture that sprung out of the coming of jack and opensats that needs to be moved on from, the whole point of this system is exactly making it self-funded, as i see it
