I'm not sure about the wildcard representation. I'll look into it and get back to you. Meanwhile, I have already worked with this json before so I can tell you how to access the information you need. The information you need can be obtained as follows:

for each_product in urlx['products']:
    if urlx['products'][each_product]['attributes']['operatingSystem']=="linux":
        #your code here

If you need pricing information from the json you need to take the product code string and look into the priceDimensions field for it. Look at the sample json and code accordingly. https://aws.amazon.com/blogs/aws/new-aws-price-list-api/
