how do I resolve Zillow API Account not authorized Error?

I am getting this error when I try to use the zillow API

from pyzillow.pyzillow import ZillowWrapper, GetDeepSearchResults
API_KEY = 'mykey'
zillow_data = ZillowWrapper(API_KEY)
address = '2114 Bigelow Ave'
zipcode = '98109'
rentzestimate = True
deep_search_response = zillow_data.get_deep_search_results(address,
                                                               zipcode,
                                                               rentzestimate)
result = GetDeepSearchResults(deep_search_response)

I get Status 6: This account is not authorized to execute this API call.

I've looked at my zillow account and have the APIs checked off, so I should have access to use the API already. I've also waited for several hours after I checked off the APIs on the zillow settings page. Anyone seen this issue before?
