API Economy

Manage APIs as the core asset that makes both the internal organization and the outside world fully benefit from your application services – and vice versa

May the best API win. Unleash the power of your applications portfolio through easy-to-use, standardized interfaces to application services. This will allow both the business and IT sides to quickly build flexible solutions that feel like their own even if they are not. And by exposing your carefully managed API catalog to the outside world, it doesn’t only open up your business in new ways to customers and partners. It might also give way to a platform for innovative ideas and solutions that you never envisioned yourself. Come to think of it, you may want to intimately know and use the APIs of others as well. Your digital breakthrough may be just one API away.


  • An application programming interface (API) provides standardized, open access to an application service or data set; it is decoupled from the actual user interface of the application.
  • A set of definitions, protocols, and tools for building application software, APIs provide the building blocks for developers to compose and enrich their application, leveraging data from multiple sources. With more and more companies opening their data sources by means of APIs, we no longer have to build all our services.
  • APIs can be managed as a product through API management platforms; they take care of versioning, scalability, quality, and monitoring of actual use.
  • APIs can be built on top of existing applications in order to provide more flexible access; new applications typically come by default with a set of accompanying APIs.
  • APIs can be exchanged with the outside world.
