The iwant.fyi demand-side protocol defines how AI agents express structured purchase intent on behalf of users, receive matched supply across multiple sources, and report outcomes back. It is MCP-native, transport-flexible, and intentionally agnostic about who matches the demand, who fulfills it, and how money moves.
Existing agentic commerce protocols are supply-side: ACP and UCP define how an agent completes a purchase at a merchant; AP2 handles payment authorization; MCP is general tool/data access. None of them defines how an agent expresses what its user wants in a structured, machine-matchable form, or how that demand persists across sessions and gets fulfilled across multiple sources.
The iwant.fyi demand-side protocol fills that gap.
