The Nutrientizer Professional Recipe Nutrition API accepts a recipe with ingredients and quantities (in grams) and returns a detailed list of nutrients with quantities per each ingredient. This API computes a recipe's total calories, lipids, proteins, carbohydrates, sugars, fibers, cholesterol, and fatty acids (including trans, saturated, monounsaturated, and polyunsaturated).
This API is RESTful with data submitted and received in JSON format.
Although the Nutrientizer Professional Recipe Nutrition API is intended for use by developers, an online version of the application is also available. With this, users can get recipe nutrients simply by inputting text.
