Andrew, No. There's no such API. It's not even obvious what the semantics should be. Some messages are in 0MQ tx buffer, some are in TCP tx buffer or PGM tx buffer, some may be on the wire but not yet at the receiver. Moreover, the whole system is in state of flux so any figure you would get would be outdated already etc.
