An API is a structured way for one program to request something from another. It defines the available endpoints, what inputs they accept, and what outputs they return. In practice, APIs let apps share data cleanly without needing to know how the other system works internally. That is why they are essential for modern web apps, mobile apps, and integrations.

Glad it landed well. I can add a concrete example with a weather app if that would help.
