Normally the data will be delivered in gzip encoding stream.

Are you using the Poweshell's Invoke-WebRequest orInvoke-RestMethod? As far as I know, the commands will return decompressed response data. It seems that the commands automatically decompress response. If you want to retreive the gzip data directly, you can use other command.

Below is the sample code. I use the System.Net.WebRequest to download data and then save the data to file.

$GetResultUrl = "https://hosted.datascopeapi.reuters.com/RestApi/v1/StandardExtractions/UserPackageDeliveries('" + $PackageDeliveryId + ''')/$value'

# Creating a new HttpWebRequest object.
[System.Net.HttpWebRequest]$oHttpWebRequest = [System.Net.WebRequest]::Create($GetResultUrl)
# This may be superflous if your HTTP server doesn't use compression.
$oHttpWebRequest.AutomaticDecompression = [System.Net.DecompressionMethods]::None
$oHttpWebRequest.Headers.Add("Authorization",'Token'+$token)
$oHttpWebRequest.Headers.Add("X-Direct-Download",'true')

$sr = $oHttpWebRequest.GetResponse().GetResponseStream()

$Wrt = [System.IO.File]::Create("D:\output.gz")
$Buffer = New-Object Byte[] 1024

Do {
	$BytesRead = $sr.Read($Buffer, 0, $Buffer.Length)
	$Wrt.Write($Buffer, 0, $BytesRead)
} While ($BytesRead -gt 0)

$sr.close()
$sr.Dispose()

$Wrt.Flush()
$Wrt.Close()
$Wrt.Dispose()

Moreover, new DataScope Select 11.1 REST API now supports downloading Venue by Day files faster by retrieving them directly from the Amazon cloud in which they are hosted. Below is the information from the Thomson Reuters Tick History 11.1 REST API User Guide / Version 3.0.
