An API billing system has an API provider system platform and an API connection platform. In the API billing system, the API provider system platform is configured such that a storage apparatus or a storage controller which controls the storage apparatus, can be added to the device configuration in addition to the API server, and the API provider system platform executes processing of the API requested from the application with a processor which differs according to its device configuration, and the API connection platform calculates the API usage fee based on the specification and utilization history of each device included in the processor upon execution of the processing of the API.
