CalorieNinjas

CalorieNinjas API

The CalorieNinjas API returns nutrition and recipe data for 100,000+ foods and beverages. It offers three endpoints: GET /nutrition for natural-language nutrition lookups (returns calories, macros, vitamins, and minerals), POST /imagetextnutrition for extracting nutrition from images containing food/beverage text, and GET /recipe for searching recipes with titles, ingredients, servings, and instructions. All requests authenticate with an API key sent in the X-Api-Key header.
