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.
The ACP category right now
Of the 22 ACP projects in the index, 1 have real traction (100+ stars) and 4 have none yet. bitrouter is the reference point at 208★. The median is 5★ — useful context before you pick a dependency from this list.
If you are choosing a stack, note that TypeScript (27%) and Python (23%) carry most of the ACP work, much of it from OrcaQubits. Projects tag themselves with acp, agentic-commerce, ai-agents more than anything else.
Freshness matters more than star count in a category this young: 7 projects shipped code in the last month, 13 in the last quarter, and 1 have not been touched in over a year. In short, activity is uneven — check the last-commit date before adopting. Newest addition: AgentFund (2026-07).
