What Is an API?

⏱ 4 hours

Every AI tool you use runs on APIs. When ChatGPT reads your files, when your calendar opens a Zoom link, when your CRM pings you in Slack, that's an API doing the work. Most people never learn how that works. So the minute a tool doesn't do exactly what they want, they're stuck.

What Is an API? fixes that. In four hours across two self-paced sessions, you'll build a clear mental model of how apps talk to each other, and then you'll build something real. No coding required.

Session 1 gives you the mental model. You'll learn how the client-server model works, what REST, SOAP, WebSocket, and GraphQL actually mean, the vocabulary you'll see in every tool's settings page, and the security basics that keep your data safe. The API Concept Explorer, an AI Tool built for this class, is there any time you want to dig deeper.

Session 2 puts it to work. You'll see how AI tools use APIs behind the scenes, learn six ways to use AI as your guide when you get stuck, pick a no-code automation platform, and build a working automation that connects two real apps.

That automation is your capstone. Describe it to the API Capstone Evaluator, get a READY verdict, and earn your badge.

This class is built for beginners: managers, small business owners, career changers, and anyone who uses AI tools and is tired of guessing how they connect. If you can use a web browser, you're ready.

You won't leave with a pile of notes. You'll leave with an automation that's already saving you time, and the confidence to look at any tool and know what's possible. Enroll now and build your first one this week.
