What is the Agentic Commerce Protocol?

The Agentic Commerce Protocol (ACP) is an open standard co-developed by OpenAI and Stripe that enables AI agents to complete commercial transactions on behalf of users. It consists of three specifications: Product Feed, Agentic Checkout, and Delegated Payment.

Yes, the protocol specification is free and open source (Apache 2.0). Standard payment processing fees apply when using Stripe for payments.

Do merchants keep their customer relationships with ACP?

Yes, merchants remain the merchant of record and keep full control over customer relationships, including customer data, emails, and support.

How are payments secured in ACP?

ACP uses Shared Payment Tokens (SPTs) that are merchant-specific, amount-limited, time-limited, and single-use. The AI agent never sees actual payment credentials.

Which AI assistants support ACP?

ChatGPT supports ACP via its Instant Checkout feature. As an open standard, any AI platform can implement ACP support.
