1 Best APIs for Allergen info in Nigeria

Edamam Recipe Search API provides access to a database of over 2 million recipes with nutritional analysis, dietary labels, and allergen information, making it one of the most nutrition-focused recipe APIs available. Edamam specializes in the intersection of food data and health data — every recipe in their database has been analyzed against USDA nutritional databases to calculate precise macro and micronutrient values per serving. Recipe search accepts natural language queries and returns matching recipes with title, source URL, yield (number of servings), ingredients list, calorie count per serving, total and per-serving nutrient breakdowns, diet labels, health labels, and caution flags. The diet labels categorize recipes as balanced, high-protein, high-fiber, low-fat, low-sodium, or low-carb based on their nutritional profile. Health labels identify recipes suitable for specific dietary patterns: vegan, vegetarian, paleo, keto, whole30, Mediterranean, DASH, and more. For Nigerian health apps, the diabetic-friendly and low-glycemic health labels are particularly relevant given Nigeria's growing diabetes prevalence. Allergen filtering is a safety-critical feature. Recipes can be filtered to exclude any of the 14 major allergens: gluten, dairy, eggs, soy, wheat, peanuts, tree nuts, fish, shellfish, sesame, and more. The API also accepts custom ingredient exclusions — users who are intolerant to a specific ingredient (like palm oil or groundnuts common in Nigerian cuisine) can exclude it from all results. This makes Edamam essential infrastructure for food apps serving users with dietary restrictions. The Ingredient Nutrition API (separate from Recipe Search) accepts raw ingredient text and returns nutritional data per serving. Text like "100g of eba" or "one cup of egusi soup" can be nutritionally analyzed after parsing. For Nigerian food and diet tracking apps, the ability to analyze Nigerian-specific ingredients and dishes provides nutritional information that generic international food databases often lack. Meal planning features allow the API to generate daily and weekly meal plans that meet specified calorie and nutrient targets while respecting diet preferences. Nigerian wellness coaches and dietitians can build client-facing meal plan generation tools without manually calculating nutritional requirements for each client. The Recipe Nutrition Widget is a visual component Edamam provides for displaying nutritional facts panels in a standard label format. Rather than building a custom nutrition display component, developers can embed the widget with the recipe ID and receive a rendered nutrition facts label matching FDA/EFSA format expectations. For Nigerian health apps that need to communicate nutritional content clearly and credibly to users, the standardized label format is more trusted than custom data visualizations. Edamam also offers a separate Food and Grocery Database API that focuses on individual food ingredients rather than complete recipes — nutritional data for raw foods like "100g of uncooked rice" or "one medium plantain." For Nigerian food tracking apps where users log individual food items they eat rather than following recipes, this ingredient-level database complements the recipe search by covering the full range of what a Nigerian user might eat at home or in a restaurant. Edamam's recipe nutrition labeling complies with FDA nutritional labeling standards, making the generated nutrition facts panels legally appropriate for food products sold in the US. Nigerian food entrepreneurs who export to the US or apply for US distribution can use Edamam's computed nutrition data as a starting point for their product's required FDA nutrition facts label.
