I am working on a project and all the project resource is on \'me-south-1\' I have other resources things in other regions.
I need to send a detailed bill to the client.
For detailed billing (with the ability to filter) the best approach is to use Cost Explorer.
By using this service you can apply a range of filters (including region), this can also be done programmatically.
Be aware that using this service does charge $0.01 per request.
$0.01
