How to get an ec2 instance cost in python?

Question

I launch an instance, stress it's cpu and delete the instance.

Using the aws cdk this takes a couple of minutes and I'm looping over 100 instance types (for benchmark purposes).

How can I get that instance's loop cost programmatically (aws cli or boto3)?

I have the instance-id

Answer 1

import boto3
import pprint

client = boto3.client('ce')

response = client.get_cost_and_usage_with_resources(
    Granularity='DAILY',
    Metrics=["BlendedCost", "UnblendedCost", "UsageQuantity"],
    TimePeriod={
        'Start': '2021-12-20',
        'End': '2021-12-28'
    },
    Filter={
        "Dimensions": {
            "Key": "SERVICE",
            "Values": ["Amazon Elastic Compute Cloud - Compute"]
        }
    },
    GroupBy=[{
        "Type": "DIMENSION",
        "Key": "RESOURCE_ID"
    }])

pprint.pprint(response)

Returns (shortened excerpt):
