The method getBalanceModels() does not exist on HanischIt\KrakenApi\Model\ResponseInterface. It seems like you code against a sub-type of HanischIt\KrakenApi\Model\ResponseInterface such as HanischIt\KrakenApi\Call\AccountBalance\AccountBalanceResponse.

        echo $balanceModel->getAssetName() . ": " . $balanceModel->getBalance() . "\n";
    }
