Lab 5: Create Weather API Key

Introduction

In this lab, we will create an API key from WeatherAPI.com — a service that provides global weather data (current weather, forecasts, historical weather, etc.). This key will allow your applications, agents, or Google Colab notebooks to access weather information programmatically.

What Is WeatherAPI?

WeatherAPI.com is a weather data provider that delivers real-time weather information, forecasts, and historical weather data via RESTful APIs.

Why Do You Need a WeatherAPI Key?

With a WeatherAPI key, you can:

  • Fetch the current weather for any city or coordinates.

  • Retrieve weather forecasts for multiple days.

  • Access historical weather records.

  • Use weather data to enhance apps like dashboards, virtual assistants, travel tools, and more!

Use Cases:

  • Weather dashboards — show temperature, humidity, and forecasts

  • Travel apps — provide weather info for destinations

  • Agriculture tools — use weather data for planning

  • AI Agents & Chatbots — answer weather questions in real‑time
