I'd probably use an API provided by the hosting service in this case, as Christian recommended, since it will be the most efficient route. But just for the sake of completeness, if you wanted to limit yourself only to Git commands, you could make a partial shallow clone of a single branch like this:

  git clone --bare --depth 1 --filter=tree:0 \
	https://gitlab.freedesktop.org/spice/win32/spice-nsis.git
  cd spice-nsis.git
  git log -1 --format=%s

That should fetch only a single object. You only get the HEAD branch because --depth implies --single-branch. You can use "clone -b" to get a different branch if you want.
