It's an e-cash based nostr client that you can use instead of ppq, but you can self host it.
The client has an integrated e-cash wallet and it puts e-cash notes in the HTTP request that goes to the LLM aggregator and receives change in the HTTP response from the aggregator. No identity required...
I have been using it since before pizza day and I haven't faced any issues so far.
