The following post indicated how to run an OData query/filter against a NuGet Feed.

Is there an equivalent available for NPM

Running something similar, e.g.

http://{proget-server}/npm/{feedName}/Packages()?$format=json

Returns a 'package not found' error. Presumably because it's searching for a package name called 'Packages()'

I can use http://{proget-server}/npm/{feedName}/{Package}/{Version}, but was wondering if there was an equivalent.
