使用aws-go-sdk检查实例类型在特定区域中是否可用

Is it possible to check if a given instance type is available in a specific availability zone using the AWS golang sdk?

According to this so question some instance types are not available on some availability zones - is there a way to get all of the availability zones in a region foo that support instance type bar?

I could not find a support for this in the SDK - even if I have to check each az one-by-one if they supprt bar that is OK for me.

Thanks in advance!
