Our latest addition to the spoonacular food API is our menu item database, which includes over 115,000 menu items from over 800 fast food and chain restaurants. Currently you can access nutritional information including calories, fat, protein, carbs, sugar, sodium, etc. Ingredient lists and suitability for different diets (e.g. vegetarian, gluten free) is not yet available.
Our fast food/chain restaurant API can be queried via the following endpoints:
Type in the menu item you're looking for, such as "Big Mac" or "Whopper". You can also search for menu items that satisfy specific nutritional requirements, such as less than 500 calories or more than 10 grams of protein.
Try it here.
For restaurants that do not provide nutritional information, there is another endpoint you can experiment with:
This endpoint can be used to estimate how many calories and how much fat, protein, and carbs a dish has based on its title and the nutritional information for recipes of this type.
