quote_checkout で得た reservation_id と、エージェントが用意した x402 PaymentPayload（base64url）を渡して決済を確定する。quote_checkout の accepts から選んだ方式に応じて payload の中身が変わる: 『eip3009』なら { signature, authorization } (EIP-712 TransferWithAuthorization の署名)、『erc20-transfer』なら { payerAddress, txHash? } (ウォレットが実行した通常の ERC-20 transferの送金元アドレス。txHash は分かれば渡す任意ヒント — 無くてもサーバがon-chain のログを検索して照合する)。erc20-transfer は送金前に必ず authorize_transfer を成功させる。eip3009 はサーバが facilitator 経由で on-chain settle し、erc20-transfer はユーザーが既に送金したものをサーバが検証するだけ。いずれも確定した注文（order_number / tx_hash）を返す。
