Which of the following metrics would measure the usage of APIs in Anypoint Platform?

The most relevant metric for measuring the usage of APIs in Anypoint Platform is the number of API invocations. This metric directly reflects how often the APIs are being called and utilized by clients or applications. By tracking the number of invocations, organizations can gain insights into their API consumption patterns, identify popular endpoints, and analyze the overall performance and demand for their APIs.

The other options do not directly correlate with measuring API usage. For instance, the number of lines of code may indicate the size of an API’s codebase but does not provide any insight into how frequently the API is used. Similarly, the number of automated test cases relates to the quality assurance process, showing how many tests are in place rather than actual API usage. Lastly, the number of Project Managers pertains to the human resources managing API projects, which does not measure usage or engagement with the APIs themselves.
