• Idempotency: Each quoteId can only be executed once and acts as the idempotency key.
• Supported Transfers: Accepts funds from a Virtual Account Group (va_2_ca) or a Crypto Wallet (cw_2_ca).
• Routing: The destination balance (toBalanceId, CA master in USD) is automatically resolved by the system; no need to pass it.
