Returns an object containing balance totals, risk information and a balances array. Asset balances are numbers in currency units; fields described as USD positions are estimates. The side parameter selects the buy or sell valuation rate. A posted balance is not a promise that the entire amount is withdrawable or available for trading; execution applies current account checks. Do not add the different balance categories together or equate these figures with a separate credit-account balance. The response can contain additional account metadata. There is no supported currency or hideZeroBalance filter on this route. Use data.lek (also repeated at the top level when present) to request the next page.
