The Linux Foundation is launching the x402 Foundation, a new industry initiative that will oversee an open protocol designed to let AI agents make payments natively over the web.
The foundation will govern the x402 protocol, developed in part by Coinbase, which allows AI agents, APIs, and applications to perform transactions directly within HTTP requests instead of using conventional checkout or billing systems.
The x402 Foundation has already attracted considerable industry support. Backers include technology companies like Amazon Web Services (AWS) and Google; financial services firms including Visa, Mastercard, and American Express; crypto companies such as Coinbase and Ripple; and retailers like Shopify.
The foundation hopes to address one of the biggest challenges facing agentic commerce: AI agents have lacked a native, secure way to transact and interact with each other. It also plans to expand x402 beyond its current capabilities by supporting multiple payment methods, including cards and stablecoins.
Defining the Shared Language
As AI agents become increasingly capable of making autonomous payments, companies across technology and payments industries have raced to build the infrastructure to support them.
Among the most important developments are agentic commerce protocols such as x402 and Google’s Agent Payments Protocol (AP2). These standards act as the shared language for agents, merchants, financial institutions, and consumers, while providing safeguards to help ensure AI agents execute transactions securely and as intended.
The rapid emergence of competing protocols has also created a fragmented environment. The Linux Foundation hopes that placing x402 under neutral governance will encourage more industry collaboration and adoption.
Momentum is already building around the protocol. For example, x402 underpins Amazon Bedrock AgentCore Payments, AWS’s suite of features that enable AI agents to pay for services like web content and APIs. The goal is to let developers focus on building AI agents rather than managing payment flows.
Waiting for the Boom
Despite the growing interest inx402, and agentic commerce at large, the technology is in early stages. Recent data from x402 found that much of the network’s transaction volume still comes from trials and pilot programs.
Even so, the level of backing behind the foundation suggests many of the world’s largest technology, payments, and financial companies except autonomous AI transactions will play a key role in digital commerce as adoption matures.
“The potential is still there, I just think the AI integration at scale is what’s holding back adoption,” Joel Hugentobler, Cryptocurrency Analyst at Javelin Strategy & Research told PaymentsJournal “It’s going to take some time for most FIs to adopt agents and therefore use Coinbase’s agentic solution. This tech will have its day but might just take some time to adopt.”
