How to get_cost_and_usage of an EC2 instance by instance id

[pedruntu]

Is there any straightforward way to get_cost_and_usage filtered or grouped by instance id?
Apparently the only way is by creating a identifier tag into each instance, activate the tags into the Cost Explorer, and then filter or group by that tags.
Instance Id is the fundamental unique way to identify an instance. Is hard to believe to me that this extensive API doesn't offer a way to use it directly for accessing individual ec2 instance cost information.
Please anybody help me with this, or confirm if it is actually not allowed.
Thanks in advance.

Hi @pedruntu it doesn’t look like you can filter/group by instance id with the get_cost_and_usage API.

As you said I think you would need to use Cost Allocation Tags as documented here and then group by that tag. You could use EC2 create-tags or the Resource Groups Tagging API tag-resources command to tag multiple EC2 instances at once.
