Ripple Joins x402 Foundation as Premier Member for AI Payment Infrastructure

Ripple joined the x402 Foundation as a premier member on July 14, 2026, alongside other cryptocurrency firms including Coinbase and Circle. The foundation, hosted by the Linux Foundation, oversees x402—an open protocol contributed by Coinbase that embeds payments directly into standard web interactions. The technology enables AI-based agents, applications, and APIs to send and receive money with the same ease as data exchange. The move addresses the need for reliable payment infrastructure as AI agents transition from making recommendations to independently purchasing services, accessing paid APIs, and completing transactions. Through open, vendor-neutral governance, the foundation ensures the emerging payment infrastructure supports various networks and payment methods without single-company control.

x402 Protocol Enables Machine-to-Machine Payments for AI Agents

The x402 protocol embeds payments directly into standard web interactions, allowing AI-based agents, applications, and APIs to send and receive money as easily as they exchange data. Markus Infranger, senior vice president of RippleX, stated: "Open standards like x402 help lay the foundation for trusted, interoperable machine-to-machine payments." The protocol addresses the operational requirements of AI agents that purchase services, access paid APIs, and complete transactions autonomously.

Ripple Develops XRP Ledger Infrastructure Supporting x402

Ripple developed XRP Ledger infrastructure that supports the x402 protocol. The infrastructure enables AI agents to transact using XRP and Ripple's RLUSD stablecoin. Infranger confirmed that Ripple has been building this capability on the XRP Ledger to support the emerging payment framework for AI-driven transactions.
