カートの内容で x402 チェックアウトの 1 回目を実行する。在庫を仮押さえし(有効期限は返り値 expires_at_unix_ms)、小計・割引・送料・合計(JPYC)と reservation_id、および PAYMENT-REQUIRED チャレンジ(base64url、x402 accepts 配列)を返す。accepts の決済方式: 『eip3009』(既定。通常の EOA ウォレットは常にこちらを選び、EIP-712 TransferWithAuthorization に署名する) と『erc20-transfer』(ecrecover 非対応のスマートコントラクトウォレット専用。payer_address を渡した予約にだけ提示される。extra.payerAuthorization.message を personal_sign して authorize_transfer を呼び、その成功後に表示額ぴったりの通常 ERC-20 transfer を実行し、txHash 任意/payerAddress 必須で submit_payment に渡す)。全 item は同一ショップである必要がある。配送が必要な商品があれば shipping を、贈答なら gift_recipient を必ず渡すこと。
