01 / UNDERSTAND

An API is a set of rules that lets one piece of software ask another for information or an action.

A weather app sends a request to a weather service. The service sends a response containing the forecast.

The app turns that data into something useful, such as a reminder to bring a jacket.

02 / TRY IT

This simulation uses safe example data and does not contact a third-party API.
