I developed a web-service that uses Google Maps API web-services to get the complete address of a zip-code in Brazil.
I created this service to give a free way to developers get complete address based on just the zip-code. That's because the government does not provide such service and neither the Postal Company. The Postal Company actually charges who wants this information and you actually have to download a database in MS Access that you have to download again in the future if you want up to date information, there is not even a charged online solution.
Hence, I just want to create this free service online based on Google Maps information, so I am not stealing data from the Postal Company.
My question is: is it allowed by Google Maps API terms and conditions? I read it but I could not find this situation.
