Is there a way to downloads VSIXes from the VS Code Marketplace without a rate limit?

Question

I want to mass download vscode and a few addons from marketplace as *.vsix.
Is there a way to authentice myself or in anyway circumvent the rate limit?

Something between 20 and 50% of all downloads get finished.

# Hashtable of direct download links with lots of links
$Addons = [ordered]@{
    PowerShell             = "https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-vscode/vsextensions/PowerShell/latest/vspackage";
    CPlusPlus              = "https://marketplace.visualstudio.com/_apis/public/gallery/publishers/ms-vscode/vsextensions/cpptools/latest/vspackage";
}

# Download from $Addons hashtable
foreach ($Key in $Addons.Keys) {
    $Url = $($Addons[$Key])
    Invoke-WebRequest $Url -OutFile "$Key.vsix"
}

I receive the following error since Marketplace has quite strict rate limits.

Invoke-WebRequest $Url -OutFile "$Key.vsix"
