An API endpoint is a specific URL or address where you send requests to interact with an API.

Think of an endpoint as a doorway that leads to a specific resource or function within a larger service. Each endpoint defines a clear path that tells the API exactly what data or action you want.

For example, if you are using a weather API, there might be one endpoint for current weather and another for forecasts. When you send a request to an endpoint, you are asking the API to give you information or perform a task at that exact location. Endpoints are important because they organize how you communicate with the API, making it easy to find and use the information or actions you need. By following these paths, your application knows exactly where to send requests and how to get the right responses.

Example: Using API Endpoints in a Weather App

Imagine you are building a weather application that shows current weather and allows users to save their favorite locations. Your app communicates with a weather API using different endpoints:

• To get the current weather for a city, your app sends a request to the /weather endpoint with the city name;
• To get a forecast for the week, your app uses the /forecast endpoint and includes the city name;
• To save a user's favorite city, your app sends data to the /favorites endpoint.

This approach lets your app organize requests by purpose. Each endpoint handles a specific type of data or action, making the API easier to use and understand.
