You can override global marshaler using httpruntime:

https://github.com/utrack/clay/blob/master/transport/httpruntime/mjson.go#L13

httpruntime.OverrideMarshaler("application/json",httpruntime.MarshalerPbJSON{
	Marshaler:       &runtime.JSONPb{EmitDefaults: true},
	Unmarshaler:     &runtime.JSONPb{},
	GogoMarshaler:   &gogojsonpb.Marshaler{EmitDefaults:true},
	GogoUnmarshaler: &gogojsonpb.Unmarshaler{},
})
