Profile

Hi HN, I built SatsAPI — a Bitcoin market intelligence API that uses L402 (HTTP 402 + Lightning Network) for pay-per-call access instead of API keys or subscriptions.The flow: GET /v1/price → 402 + { invoice: "lnbc3n1p...", payment_hash: "abc123" } pay invoice (any Lightning wallet) GET /v1/price?payment_hash=abc123 → 200 + { price, rsi, macd, trend, ... } 8 endpoints covering price/technicals, mempool fees, on-chain metrics, derivatives, AI-generated signals and a full market summary. Costs range from 2 sats (~$0.001) to 200 sats (~$0.12).The main thing I wanted to test: can L402 work as a real auth mechanism for a production API? Turns out yes — it's been live for a week on mainnet and alr
