I'm trying to use the GoDaddy API for checking if a domain is available to register, but I'm getting inconsistencies with the results. For instance, checking to an unregistered domain like is returning the domain is already registered, but when searching for it in the official registar of .com.br domains (the registro.br website), that domain is available. This is happening with lots of domains.
I've tried using both the FAST and FULL search methods of the API.
How can I know that the API is reliable in order for me to provide a UI so that my users can search and register a domain in my system?
