ACP (Agentic Commerce Protocol) standardizes how agents conduct commerce end-to-end: discovering products and services, negotiating terms, paying, and confirming fulfillment. Backed by Stripe and OpenAI, it is a higher-level layer that can sit on top of payment rails like x402 or MPP — the difference between "paying for a request" and "buying a product".

Below are the projects implementing or integrating ACP: checkout flows for agents, merchant-side handlers, and commerce demos.

See the ACP guide for how it works, or compare the full stack on all agent payment protocols.

Frequently asked questions

What are the best ACP projects for AI payments?

We currently track 21 ACP projects in the directory, drawn from open-source repositories building on x402 and agent payments. The list above is sorted by GitHub stars and updates as new projects are submitted and crawled.

What is x402, and how does it relate to ACP?

x402 is an open standard for paying for an HTTP resource: a server replies with HTTP 402 and payment terms, the client pays (usually USDC), and the request is fulfilled. The ACP projects above implement or build on this flow.

How do I get a project listed here?
