That's not possible right now. That JSON endpoint is specifically to pass into the SDKs, so it contains the minimum fields necessary. We're planning to add a full REST api soon that will have a lot more info.

For now I workaround this limitation by adding a dummy rule to the feature that holds and data I need. (very ugly patch )
It will be so much nicer if I could add metadata to the feature, get it the json and query for it in the sdk
