Submit the EIP-712 signature for a quote that was accepted (you received a quote:accepted message on the post-trade WebSocket). Sign the order from that message with the wallet key for order.maker, then POST the signature here before the confirmationDeadline. The backend verifies that your signature recovers to order.maker, returns the signed order to the trader, and emits quote:confirmed to you (and quote:rejected to other makers).
If you miss the confirmationDeadline, the backend falls back to the next-best maker and this endpoint returns 404 no_pending_acceptance. Keep your USDC approvals set ahead of time so signing is instant.
