"UnionPay has released the Agentic Payment Open Protocol (APOP) framework – UnionPay's solution for agent-based payments. The APOP framework aims to establish a unified trust mechanism and interaction paradigm. By connecting players in the agentic payment ecosystem through trusted routing, it enables any compatible agent, merchant, financial institution, and technology platform to integrate on a plug-and-play basis, and to easily and securely participate in the complex processes of agentic payments."
