What is agentic commerce?

Agentic commerce is a category of transactions where an autonomous AI agent, such as ChatGPT, Gemini, or Microsoft Copilot, discovers products, compares options, and completes purchases on behalf of a human buyer. The buyer still authorizes the spend, but the path from intent to checkout runs through the agent rather than the buyer's own clicks on a merchant website.

What does it mean for a checkout to be AI-agent-ready?

A checkout is AI-agent-ready when it can accept a purchase initiated by an autonomous AI agent through a standardized protocol (ACP, UCP, or both) without requiring the agent to navigate a human user interface. This requires a machine-readable product catalog, agentic checkout API endpoints, delegated payment token support, and visibility infrastructure to measure and optimize agent-driven traffic separately.

What is the difference between ACP and UCP?

ACP (Agentic Commerce Protocol) is co-developed by Stripe, OpenAI, and Meta. It powers ChatGPT Instant Checkout and focuses on the checkout flow. UCP (Universal Commerce Protocol) is co-developed by Google and Shopify. It powers commerce inside Google AI Mode and Gemini and covers the full journey from discovery through fulfillment. Most enterprise merchants implement both, since agent traffic comes from multiple platforms.

Is agentic commerce safe from a fraud and compliance perspective?

It can be, with the right infrastructure. The protocols themselves are designed with security in mind: scoped tokens, short expiration windows, programmatic controls, and full audit logging. The compliance burden falls on the merchant and their PSP to maintain PCI DSS Level 1 certification, apply appropriate fraud rules, and ensure that the authentication flow handles both customer-present and agent-initiated cases. Merchants who operate inside a PCI DSS Level 1 compliant orchestration environment with fraud rules tunable per traffic type are well positioned. Merchants who try to bolt agentic flows onto an aging PCI footprint typically struggle with audit scope.
