You can create a class that represents the api connection and use
method_missing
to collect all the API calls to one place in your code, like this:

class ApiWrapperClass
  def method_missing(meth, *args)
    retries = 0
    begin
      SomeAPI.send(meth, *args)
    rescue API::Exception
      ...
    end
end

x = ApiWrapperClass.new
x.api_call( .... )
