“A-P-I”

A doorway that lets two pieces of software talk to each other.

Think of it like…

A restaurant server carrying orders between you and the kitchen.

Everyday example

An app showing live weather it pulled from a weather service.

Construction example

Your scheduling software sending job details straight into your accounting software.

Business example

A store's website checking inventory in the warehouse system in real time.

Why this matters

APIs are how AI plugs into the tools you already use instead of living on an island.

One-sentence summary

An API is the doorway software uses to talk to other software.

Try it yourself

Name two tools you use that don't talk to each other. Connecting them would be an API job.
