Google's new open protocol secures AI agent transactions - and 60 companies already support it
"The next level of AI assistance in e-commerce is agent-led AI transactions, where your agent can place orders on your behalf, saving you time as a consumer and connecting your product to buyers if you're a merchant. Also: Gartner says add AI agents ASAP - or else. Oh, and they're also overhypedWhile the technology is promising, there are also security concerns because an agent has access to your payment details. To address those concerns, Google has launched its new Agent Payments Protocol (AP2), which the company describes as an "open protocol developed with leading payments and technology companies to securely initiate and transact agent-led payments across platforms.""
"AP2 can be used as an extension of the Agent2Agent (A2A) protocol and the Model Context Protocol (MCP). Similar to how MCP allows users to connect AI tools to their databases with confidence, the AP2 standard lets users, merchants, and payment providers transact with AI agents securely.

Agent-led AI transactions let agents place orders for consumers and connect merchants to buyers, saving time and automating commerce. Agents accessing payment details create security and accountability concerns that require verification and clear responsibility. Google launched the Agent Payments Protocol (AP2) as an open standard developed with payments and technology companies to securely initiate and transact agent-led payments across platforms. AP2 can extend Agent2Agent (A2A) and Model Context Protocol (MCP), validate user authorization, confirm agent behavior to merchants, and help identify accountability when actions fail. AP2 supports credit cards, stablecoins, and real-time bank transfers as a unified payment standard.
