Google has upgraded its Agent2Agent (A2A) framework, which now allows agents to pay each other. With the new Agentic Payments Protocol (AP2) and its x402 extension, Google is enabling AI agents to handle stablecoin payments directly. It is said to unlock instant micropayments and automation models that traditional payment systems can’t match.
Until now, Google Cloud’s A2A allowed AI agents across platforms to communicate and collaborate on tasks. Adding AP2 means these agents can exchange value, not just information. And with x402 as the first stablecoin facilitator for AP2, agents can monetize services, pay peers, and execute transactions on behalf of users, all without human oversight.
