x402

x402 is a payments protocol built directly on HTTP, enabling seamless, real-time micropayments for web content and services without requiring a separate blockchain or cryptocurrency wallet. It is designed for developers and content creators who want to monetize digital assets—such as APIs, articles, or streaming data—on a per-request basis. Its interesting because it reimagines internet payments as a native part of the web’s infrastructure, potentially unlocking new business models for pay-per-use or ad-free experiences.
