Answer: AWS CloudTrail

AWS CloudTrail is the correct service for viewing API calls to AWS services. Here's why: - **AWS CloudTrail** records API calls and related events made in your AWS account, providing a history of AWS API calls for your account - **Amazon CloudWatch** is for monitoring and observability - it collects monitoring and operational data in the form of logs, metrics, and events - **AWS Config** is for resource inventory, configuration history, and configuration change notifications - **AWS Artifact** is for on-demand access to AWS security and compliance reports CloudTrail enables security analysis, resource change tracking, and compliance auditing by logging API activity across your AWS infrastructure.
