Damjan is right. However, vpp is willing to start a binary API messages over
sockets server.
With a strong warning that not every api works when vpp_api_test runs over
sockets, here's how to make it play:
# vpp unix { interactive cli-listen /run/vpp/cli-vpp1.sock } api-segment {
prefix vpp1 } socksvr { socket-name /run/vpp/api_1.sock }
and
# vpp_api_test socket-name /run/vpp/api_1.sock chroot prefix vpp1
# show_version
Or some such...

You cannot use CLI socket with VAT. They are completely different things.
