About
x402 is an open standard that enables internet-native payments using the HTTP 402 status code. Servers respond with payment requirements, clients pay in stablecoins, and access is granted. It's designed for machine-to-machine payments, particularly AI agents paying for API access.
Stablecoin Relevance
x402 represents the next frontier of stablecoin usage: programmatic micropayments between AI agents and APIs, turning stablecoins into internet-native money.
