Access to denied to S&P credit rating data - Excel download available but API not

I have problems doing the following call:

ek.get_data(['AU1YT=RR','UA1YT=RR'],['TR.IssuerRating','TR.IO.Outlook'],
{'IssuerRatingSrc':'SPI'})

I get the following output:

( Instrument Issuer Rating Outlook
0 AU1YT=RR <NA> Neg
1 UA1YT=RR <NA> Sta,
[{'code': 246, 'col': 1, 'message': 'Access to S&P data denied', 'row': 0},
{'code': 246, 'col': 1, 'message': 'Access to S&P data denied', 'row': 1}])

But when I go to the platform I can download the S&P data in the Excel format. Can I get access to the API to automate this call?
