  title: Kraken Withdraw Funds with Fee Preview
  summary: Check balance and withdrawal fees, withdraw to a saved address, then track status.
  description: >-
    A safe withdrawal flow for the Kraken Spot REST API. It reads the account
    balance, previews the fee and limit for the chosen withdrawal address (key),
    submits the withdrawal, and then reads recent withdrawal statuses so the
    caller can track the resulting transfer by its reference id. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
