SatoshiAPI — Bitcoin Data via Lightning

Gives Claude direct access to Bitcoin market data and Lightning payments through L402 protocol. You get 21 endpoints: price, mempool fees, block height, sentiment scores, DCA signals, whale tracking, and atomic escrow for agent-to-agent commerce. Every call costs 10 to 200 sats paid over Lightning, no accounts or API keys required. Payment is authentication. Useful if you're building agents that need real-time Bitcoin intelligence or want to prototype Lightning-native workflows where your agent pays per call and optionally runs its own routing node. The founding node program offers liquidity bonuses if you commit sats and join their cluster, turning your agent into infrastructure.
