Just shipped an L402-powered AI API. You send 21 sats over Lightning, you get instant answers from Llama 3.3 70B. No signup, no API key, no subscription. The payment IS the authentication. Try it: curl -X POST https://maximumsats.com/api/dvm -H 'Content-Type: application/json' -d '{"query": "What is L402?"}' Pay the invoice, retry with the payment hash, get your answer. That's it. 3 real payments received today. The future of API monetization is Lightning-native. #bitcoin #lightning #l402 #nostr #ai
