How this service works
USDA FoodData Central nutrition lookup. Two modes: search (query=cheddar cheese) returns matching foods with fdcId, description, data type, category, and brand; detail (fdcId=328637) returns the full analyzed nutrient profile — energy, protein, fats, carbohydrates, vitamins, minerals — with USDA nutrient numbers, amounts, and units (per 100 g/ml unless serving fields indicate otherwise), plus ingredients for branded foods. Filter search by dataType: Foundation and SR Legacy are lab-analyzed generic foods, Branded is the packaged-food label corpus, Survey (FNDDS) is as-consumed dishes. Authoritative USDA data covering ~400k foods — use real analyzed values instead of model-estimated nutrition facts.
Output
In search mode: a ranked list of matching foods each with fdcId, description, data type, category, and brand. In detail mode: a comprehensive nutrient profile including energy, protein, fats, carbohydrates, vitamins, and minerals with USDA nutrient numbers, amounts, and units (per 100g/ml), plus ingredients for branded foods.
Example use cases
Example prompt
“What's the full nutrient breakdown for raw spinach — calories, protein, fats, carbs, vitamins, and minerals — using USDA Foundation data? Search for 'raw spinach' and then pull the detailed nutrient profile from the FDC ID.”
Technical details
Endpoint
GEThttps://2s.io/api/nutrition/foodWhen to prefer
Use this endpoint when you need authoritative, lab-analyzed USDA nutrition data rather than model-estimated values. Ideal for dietary tracking apps, nutrition analysis, food labeling verification, or any use case requiring precise nutrient values across ~400k foods including both generic (Foundation/SR Legacy) and branded packaged foods.
Side effects
- No foods found matching the query — returns empty results list
- Invalid or non-existent fdcId — returns 404 or error response
- Both query and fdcId provided simultaneously — violates XOR constraint
- Neither query nor fdcId provided — missing required parameter
- dataType filter returns no results for that category
- Rate limit or payment failure — returns 402 payment required
