If you have a System Manager agent installed on your instances you can use DescribeInstanceInformation API to find that information:
$ aws ssm describe-instance-information --query 'InstanceInformationList[*].[InstanceId,PlatformType,PlatformName]' --output text --filters Key=InstanceIds,Values=i-016073859e4b31111
