Combo

Sell an open combo position back to pUSD

Sells shares of an open combo through the RFQ gateway. Preview it first with POST /combo/cash-out-quote. minProceedsUsd is checked against GROSS proceeds, before the platform fee is deducted — so the amount that lands can be below the floor you set by the fee amount. Size the floor accordingly. Same up-front rejection as the quote endpoint: a combo with a lost leg, or one that has fully resolved, cannot be cashed out (no maker quotes a worthless or settled combo) and fails fast rather than hanging. Unlike the quote endpoint this is not rate limited — selling a position is economically self-limiting. Auth & scope. Requires trade:execute for polymarket plus the mutation gate.
