Polymarket US integration for Claude and Codex

Cancel all authenticated Polymarket US open orders, optionally scoped to specific market slugs. This is broad and destructive for remaining open quantities; omit slugs only when the user clearly asks to cancel every open order. Already executed fills and positions remain, so verify open orders afterward when confirmation matters.

Cancel up to 20 Polymarket US open orders in one request. Use only when the user explicitly asks to cancel the batch. Cancellation removes remaining open quantity but does not undo fills or positions, and batch responses can require per-order follow-up reads to verify final state.

Cancel one Polymarket US open order by exchange-assigned order ID. This is a destructive mutation of the remaining open quantity and should only be used when the user explicitly asks to cancel. Already executed fills and resulting positions remain; confirm order state afterward when precision matters.

Create a live Polymarket US order intended to close an existing position in one market. Use only when the user explicitly asks to close that position. This can trade immediately, leave residual exposure if not fully filled, or be rejected for market, liquidity, risk, or funding checks; inspect the returned order state before confirming the position is closed.

Submit up to 20 live Polymarket US orders in one request. Use only after the user explicitly asks to place the batch and, when practical, after previewing the same orders. This mutating action can consume buying power and create exposure across multiple markets; read per-order statuses because a batch can contain accepted, filled, and rejected orders.
