The main README.md in the root should be enough to get started, it has a quick example section for zsock (and all other classes). Else the zsock_test selftest method is another good example.
In general it's pretty easy, something like:
zsock_t *a = zsock_new_pair("@inproc://foo");
zsock_t *b = zsock_new_pair(">inproc://foo");
zsock_send(a, "p", ptr0);
zsock_recv(b, "p", &ptr1);
zsock_destroy(&a);
zsock_destroy(&b);
