i.e. I'd prefer to be able to just pay for each search with cashu tokens directly.
An other ok workflow would be nostr login + nwc
This seems like it would work well.. with the trade-off of potentially linking an npub to searches, I guess. I was picturing more like 1 browser extension wallet that manged cashu tokens/mints/seed phrase locally - from which any other browser app could ask for permission to spend tokens... similar to how nostr clients ask a browser extension to sign notes. But, I'm getting well out of my feasibility depth here.
