Send deal_id, side ('give' or 'want') and the payload itself; the payload is hashed so either party can prove later what was delivered. Returns the deal status, whether both sides have now delivered, and the release state of the escrow. Nothing but the flat call fee is charged — the goods, not USDC, are what trade here.",
