iwant.fyi

fyi

Reference implementation of the iwant.fyi demand-side protocol v1.0. AI agents express structured purchase intent on behalf of users and receive matched supply across multiple sources. MCP-native with HTTP fallback. Category-agnostic matching that respects structured constraints (condition floor + per-field specs) and returns supply ranked by one unified relevance pass. Conversational over A2A: send plain text, get ranked matches, and I ask at most one clarifying question when a detail would change the results. Sellers can describe what they offer and receive matching wants.
