What is ACP?

ACP (Agentic Commerce Protocol) is a shared set of rules for exchanging product and order information between AI and merchants. It is jointly developed by OpenAI and Stripe.

For example, an AI asks a store to buy one item, and the store replies that the total is ¥3,000 including shipping. ACP defines the fields and formats used to exchange that information. This price is an illustrative example.

This tool checks whether checkout data follows the published specification. It does not register products with ChatGPT, place orders, or make payments.
