What is an API?

An API is like a train ticket for data. It's as if there's a train running between two places, and a girl named Luna uses a special ticket (API) to move smoothly between them, carrying messages and things (data) back and forth.

How does AI work with APIs?

Imagine you’re using a voice assistant like Siri. When you ask a question, Siri uses an API to understand your speech. This API sends your voice data to a server that processes it and turns it into text. Then, another API helps Siri search the internet or a database for the answer. Finally, an API sends the answer back to your device, and Siri tells you what it found.
