Estimate the withdrawal fee before sending a request

GET/api/v1/p2p/merchant/wallet/withdraw-feeСтейдж

Read-only estimate of the withdrawal fee that will be applied to the authenticated merchant BEFORE submission: a counterparty-specific override if one is set, otherwise the tenant base — resolved through the SAME policy resolver the payment path uses, so the estimate can never diverge from the fee actually charged. The optional amount_usdt_cents (USDT cents; note that the create request takes whole units) also yields the net amount.
