For sure, I use the AWS APIs to gather the data but there's no single API for all this, I aggregate it from different services and across regions.
AWS also has some dashboard in the AWS console similar to this but it doesn't have cost information for the resources, it's not easy to track the resources that generate the costs, and you can't extract the data out of it for further automated processing.
They also have visibility for this in the Cost Intelligence dashboards, but you need those deployed in the account.
This tool runs from your local machine and you can point it to different accounts with just using a different AWS CLI profile, and you don't need to deploy anything in the target account.
I show it all on a single view across services(looks and feels much like a spreadsheet), each resource with its price tag next to it and also showing some metrics, like load balancer traffic numbers that should inform consolidation decisions.
Data export functionality is not there yet but we may add it soon if there's demand for it or someone contributes it.
