[Japan] GMO Payment Gateway (GMO-PG, Tokyo, Japan) completed the development of a proprietary payment solution in June 2026 for its comprehensive online payment service, “PG Multi-Payment Service.” This solution adopts the “Universal Commerce Protocol (UCP),” an open, common specification that connects AI agents with e-commerce businesses.
This initiative anticipates the growth of “Agentic Commerce,” in which AI agents search for products and complete purchase procedures on behalf of users. As UCP-compliant AI agents emerge and expand, the company aims to build a payment infrastructure that enables e-commerce operators and various online service providers to support Agentic Commerce.
Driven by advances in generative AI, “Agentic Commerce”—where AI agents understand user intent and autonomously assist with product searches, comparisons, and purchase procedures—is garnering attention both domestically and internationally as the next-generation form of online transactions.As AI agents become integrated into the purchasing process, the consumer shopping experience is undergoing significant changes, and e-commerce operators are beginning to be required to prepare for future demand for purchases made via AI agents.
In response to this trend, in January 2026, Google and various industry companies announced the “Universal Commerce Protocol (UCP)” as an open, common specification for connecting AI agents and e-commerce systems.UCP is a specification aimed at standardizing the interface for commerce transactions mediated by AI agents across industries; it is not tied to any specific AI agent or service, and is intended to be used by multiple UCP-compliant AI agents.
GMO-PG is actively working to build a next-generation payment infrastructure designed for the use of AI agents. In June 2025, it began supporting the Model Context Protocol (MCP)—a specification for integrating with external systems such as AI agents—in its online payment service “fincode byGMO.”
Building on these efforts, GMO-PG has now developed a proprietary payment solution based on UCP for its “PG Multi-Payment Service.” This proprietary solution will provide an environment capable of meeting new purchasing demand from agent-based commerce as the number of UCP-compliant AI agents continues to grow.
As of August 6, 2026, the e-commerce shopping carts scheduled for integration include ecbeing (ecbeing),Color Me Shop by GMO Pepabo (GMO Pepabo), MakeShop by GMO (GMO MakeShop), GMO Cloud EC (GMO MakeShop), ecforce (SUPER STUDIO), F.ACE (Diamond Head),W2 Commerce (W2), and Mercato (Mercato).
