There isn't any.

The zip compression is only avialable via the Explorer GUI. It's implemented
as a DLL (zipfldr.dll) which is loaded into the Explorer process space.
There's no stand-alone EXE or equivalent command-line option, to zip or
unzip files.

Microsoft licensed the zip compression code from a 3rd party company. Part
of the deal was there'd be no compression command, so as to not impact sales
of 3rd party compression utilities. If you need a command-line commpression
command, you'll need to find a tool to do the job, such as Winzip.

Hope it helps,
