1. A computer system for collecting and monitoring performance data for a plurality of application programming interfaces (APIs), comprising: a hardware memory device that stores program instructions; and a processor that executes the program instructions and causes the computer system to: obtain one or more various measurements of performance of the APIs on one or more computing devices operably connected to a network; and assess a performance status for each of the APIs based on the obtained one or more various measurements of performance; display the performance status for each of the APIs; initiate a live API call to a running application on the one or more computing devices using parameters of a method of one of the APIs; and receive data in an open standard format used by the API for transmitting data from a software application on the one or more computing devices.
