Did you know there are over 200 million APIs floating around the digital world right now?
That’s like walking into the world’s biggest library… except none of the books are labeled, the shelves are randomly stacked, and every librarian speaks a different language.

The article discusses the challenges faced in API discovery due to the overwhelming number of APIs available without proper labeling or organization, likening it to a chaotic library. It highlights the limitations of current methods, the need for knowledge graphs to streamline API management, and the benefits of advanced semantic technologies for better organization. The piece argues that as more APIs are created, intelligent systems like knowledge graphs will be essential for orchestrating digital services effectively, enhancing workflow automation, and ensuring compliance with business rules, ultimately transforming how organizations manage and utilize APIs.
