AI agents require native payment and trust mechanisms to operate autonomously at scale. x402 supports embedding on-demand payments directly into APIs using stablecoins, eliminating the need for subscriptions or manual billing. At the same time, ERC-8004 provides on-chain identity and reputation for agents and services, enabling verifiable execution histories and trust assessments of trading counterparts. These protocols address key infrastructural bottlenecks in payment settlement and reputation, laying the essential foundation for competitive operation of autonomous agent ecosystems.
