Developers, he added, can access sample code, software development kits, and API descriptions. "Also, API management enables you to offer a managed API that will exhibit a high quality of service so these APIs are monitored and you can understand the usage of the APIs."
Open APIs are published on the Internet and shared freely. A startup software company, for example might publish a series of APIs to encourage third-party developers in vertical industries to be innovative and figure out new ways to use the startup's software product. In theory, it's a win-win business arrangement.
