Ok, did some research.
It looks like outpost/smt based tribes are not reporting tokens in the API. I don't know if there is a second api, or it is just another oversight. I contacted the dev and let them know and waiting for a reply to see if there is any solution. For now there isn't anything I can do since the data just isn't available.
If I get a solution, I will work it in and try to let you know.
