Lightning Labs launches pi402 for token-based AI payments on Bitcoin

By PulseAugur Editorial · [1 sources] ·

Lightning Labs has released pi402, an open-source extension designed to enable AI agents to pay for inference services using Bitcoin on the Lightning Network. This system operates without requiring user accounts, API keys, or credit cards, instead utilizing an L402 payment protocol. When an agent makes a request, it receives an HTTP 402 response containing a Lightning invoice and a macaroon credential, which its wallet then uses to pay based on predefined spending limits. ScriptMasterLabs offers a complementary Verdict Protocol that adds a decision-making layer, costing $0.25 USDC per decision, to evaluate the necessity and fairness of AI inference requests beyond simple payment limits. AI

IMPACT Enables new payment models for AI inference, potentially reducing friction for AI agent-to-agent transactions.
