APImetrics has announced the launch of the APImetrics API Performance Test Solution, a new kind of end-to-end API testing and monitoring service that tests an API's functionality and speed of response using complex, authenticated API calls.

Using API calls allows the APImetrics service to provide comprehensive monitoring and analysis of the actual performance of APIs.
