On subscription, yet the error suggests I am not

I am on paid subscription for data. When I request for market history of feed=otc, in, say

out = api.get_bars('GS', TimeFrame(15, TimeFrameUnit.Minute), start, end, feed='otc')

I get the following, subscription does not permit querying OTC data

subscription does not permit querying OTC data

May I ask how I can confirm if I am accessing any of the subscription limited data?
