Sometimes, ZIP utilities have a command that just checks the integrity of the archive, without actually unZIPping its contents.
If you are unZIPping to an empty directory, you could see if any files got created. Or, if you know the name of a file that's supposed to be present in the output, or a pattern like YYYY-MM-DD.TXT you could search for that.
