The Zomato API tutorial provides a comprehensive guide on integrating features from the Zomato platform into applications, offering access to data from over 1.5 million restaurants in 10,000 cities globally. To use the API, developers must first acquire an API key by creating a free Zomato account and then connect to the API via RapidAPI. The basic plan allows up to 1,000 free calls per day, with additional access available through partnerships. The API includes 17 endpoints, enabling users to retrieve various types of information, such as restaurant categories, city details, restaurant collections, daily menus, and available cuisines. The tutorial also compares the Zomato API with alternatives like Spoonacular, Nutritionix, and Yelp, highlighting different features and pricing structures to help developers choose the best option for their needs.
