Which AWS service should a cloud engineer use to view API calls to AWS services?

Explanations:

Amazon CloudWatch is primarily used for monitoring resources and applications, providing metrics and logs, but it does not log API calls specifically.

AWS CloudTrail is specifically designed to log API calls made to AWS services. It provides detailed information about the requests, including the identity of the requester, time of the request, and the resources involved.

AWS Config is used for assessing, auditing, and evaluating the configurations of AWS resources. While it tracks changes in resource configurations, it does not log API calls.

AWS Artifact is a service that provides access to compliance reports and security and compliance documentation. It does not log API calls or provide visibility into AWS service usage.
