P402 Protocol

P402 Protocol serves as an intelligent AI payment router, bridging the gap between AI applications and diverse LLM providers. It streamlines access to over 300 models by offering a single OpenAI-compatible endpoint, while handling complex routing decisions based on cost, quality, or speed. Integrating the x402 protocol, P402 facilitates gasless micropayment settlement in USDC on the Base blockchain, dramatically reducing transaction fees. Furthermore, it empowers autonomous AI agents with critical spending guardrails through session budgets and provides real-time analytics to optimize AI costs.
