weather-api API
Overview
weather-api is a lightweight, open-source RESTful API that provides current weather data for cities around the world with no authentication required. It is built on top of open data sources and is perfect for learning how to consume a weather API without worrying about API keys or rate limits. Beginners can get started in minutes by simply querying a city name.
Beginner Tip
No API key is needed. Just pass a city name as a path parameter and you will get back current temperature, humidity, and weather conditions in a simple JSON response.
