I'm building a framework for nip90 data vending machines. The idea is that people can run and/or build their own DVMs easily. Clients like nostrudel and others currently start to integrate the first DVM services. By running a DVM connected to a service/API/local processing capabilities, you can monetize that service on any nostr client that supports NIP90. And I think by running variations of tasks the ecosystem grows and gets better.
