- Problem solved
- The core problem solved by APIs is the complexity of inter-component communication and the need for software reuse and modularity. Before APIs, integrating software components or making one program interact with another system was often a bespoke, arduous, and error-prone process, requiring deep knowledge of internal implementations and leading to tightly coupled, monolithic systems that were difficult to maintain and scale. APIs provide a stable, documented interface, abstracting away this complexity and fostering interoperability.
