Building satsgate (open-source): a hosted Lightning L402 paywall for APIs/AI agents. If your agent calls an endpoint, you can charge sats per successful call (402 challenge -> pay invoice -> retry with L402 token). No accounts, no webhooks. Looking for 3–10 beta operators (trial: 1000 sats -> 200 credits). Repo: https://github.com/Mike-io-hash/satsgate #bitcoin #lightning #l402 #ai #agents #opensource #fastapi #buildinpublic
