Introducing ACP: An Open Protocol for Agent-to-Agent Commerce

I want to introduce something I have been working on and get feedback from the builder community. ACP stands for Agent Commerce Protocol. It is an open specification that defines how autonomous AI agents negotiate terms, settle payments conditionally, and produce verifiable receipts of economic activity. If you are building multi-agent systems and have run into the problem of "how does Agent A pay Agent B, and how do I verify the work actually happened," this is what ACP is designed to solve. Why this matters now The agent ecosystem is moving fast. MCP (Model Context Protocol) gave us a standard way for agents to connect to tools. A2A gave us a way for agents to communicate with each other. The Agentic AI Foundation just launched under the Linux Foundation to steward these standards. But there is a missing piece. None of these protocols addresses the economic layer. How do agents agree on a price? How do you escrow funds against a conditional outcome? How do you split the payment acros
