What is an API? | The Invisible Messenger That Runs the Entire Internet!

You use APIs every single day, but do you know how they act as the Invisible Messenger of the internet? 📨 In just 2 minutes, we explain What is an API? using the simple "Restaurant & Waiter" metaphor. We clarify why apps like Uber need APIs to function, and how APIs turn a passive AI Chatbot (Brain in a Jar) into an active AI Agent that can actually do things. Crucially, we also cover API Limits—why you can't just ask AI to check "every stock price in the world," and why Rate Limits exist. In this video, you will learn: -The Metaphor: Why an API is like a Waiter (Request vs. Response). -The Real World: How Uber uses Google Maps APIs. -The AI Connection: Giving AI "Hands" and "Eyes" to browse the web. -The Catch: Understanding Rate Limits and Costs. -------------------- Keywords in 2 Minutes breaks down complex tech buzzwords into bite-sized, easy-to-understand videos.
