Does anyone have a list of boto3 function name which list resources for each service?

There isn't a universally agreed-upon list of all boto3 functions for listing resources across all AWS services. However, you can typically find the relevant functions in the boto3 documentation for each service. Common naming conventions in boto3 include methods that start with list_ or describe_, depending on the service and resource. For example, list_buckets() for S3, describe_instances() for EC2, and so on.

For your use case of identifying resources across all AWS accounts and regions, you might consider using AWS Config or AWS Organizations for a more centralized approach. AWS Config can track resource inventory and changes across your AWS account, while AWS Organizations can help manage policies and resources across multiple AWS accounts.

The open-source tool at https://github.com/awslabs/resource-lister allows you to view resources across accounts /region, though it currently has limited coverage and supports only 27 services.
