x402 is an open, neutral standard for internet-native payments that enables instant, low-cost transactions for digital services by integrating payment directly into HTTP requests. It solves the problem of slow, friction-heavy payment processes for API monetization, agentic commerce, and paywalled content. The standard targets developers and executives in B2B settings, particularly those building or using APIs and digital services. It is positioned as a free, open, and neutral alternative to traditional payment systems, with zero protocol fees, no accounts, and no centralization.
