Open source
ACP is open source and community-designed under the Apache 2.0 license. Businesses can implement the specification to transact with any AI agent or payment processor.
Built for businesses
With ACP, businesses maintain their customer relationships as the merchant of record, retaining control over which products can be sold, how they're presented, and how orders are fulfilled.
Supports complex flows
ACP supports flexible configurations for any commerce type, including physical and digital goods, subscriptions, and asynchronous purchases.
AI commerce that works for everyone
For businesses
Reach more customers. Sell to high-intent buyers by making your products and services available for purchase through AI agents—all while using your existing commerce infrastructure.
For AI agents
Embed commerce into your application. Let your users discover and transact directly with businesses in your application, without being the merchant of record.
For payment providers
Grow your volume. Process agentic transactions by passing secure payment tokens between buyers and businesses through AI agents.
AI agents
Instant Checkout in ChatGPT
Integrate ACP to participate in Instant Checkout in ChatGPT. You can process agentic payments with Stripe or any other ACP-compatible payment service provider.
Frequently asked questions
Who can use the Agentic Commerce Protocol (ACP)?
Any business or AI platform can implement the ACP spec to participate in agentic commerce, helping buyers discover and transact directly within AI interfaces.
Which AI agents are available to businesses who implement ACP?
Any AI agent can call an ACP-enabled checkout. Businesses can then choose to accept or decline transactions on a per agent, per transaction, or custom logic basis. OpenAI is the first AI platform to implement ACP with Instant Checkout in ChatGPT.
Does implementing the protocol mean my products will automatically be listed through AI agents?
No, each AI platform will manage their own process for how businesses can participate. If your business wants to participate in Instant Checkout in ChatGPT, you'll need to apply. We'll post additional AI platforms that adopt ACP on this site along with instructions for how to participate.
Can merchants use their current payment processor with ACP?
Businesses can use ACP with any compatible PSP—Stripe is the first compatible PSP with its Shared Payment Token. If you're a business on Stripe, you can learn more about Stripe's agentic commerce solutions in its documentation.
How can AI platforms identify which merchants have implemented ACP?
We're working to create discovery mechanisms for AI platforms to identify businesses that have implemented ACP. AI platforms interested in adopting ACP can reach out to [email protected].
Developed to create standards for open and secure AI commerce.
As transactions move from websites to AI workflows, the internet needs a new set of standards for open and secure commerce. Stripe and OpenAI developed the Agentic Commerce Protocol to define a common language for how agents and businesses transact—including coordinating checkout and securely sharing payment credentials. We built ACP as a collaborative, open source standard and we welcome your feedback on how to improve it.
