How this service works
Full normalized nutrition profile for a USDA FoodData Central food by fdc_id: calories, macros and micronutrients per 100g and per serving.
Output
A normalized nutrition object containing calories, macronutrients (protein, fat, carbohydrates, fiber, sugar), and micronutrients (vitamins, minerals, etc.) expressed both per 100g and per serving size for the requested USDA FoodData Central food item.
Example use cases
Track macro and micronutrient intake
“I'm trying to hit my daily protein and vitamin targets — can you grab the complete nutrition breakdown for USDA food ID 168209 so I can see exactly how much of each nutrient I get per serving?”
Build a balanced meal plan
“I'm meal-prepping this week and need to compare the full nutritional profiles of several ingredients. Pull the detailed nutrition data for USDA foods 747448 and 325089 — I need the calories, macros, and key micronutrients per serving to balance my meals properly.”
Analyze dietary restrictions and allergies
“My client has specific micronutrient needs and we're using USDA FoodData Central as our reference. Can you retrieve the complete normalized nutrition profile for food ID 463845, including all vitamins and minerals, so we can verify it fits their dietary requirements?”

Endpoint
GEThttps://payai.agentstools.dev/nutrition/foodWhen to prefer
Use this endpoint when you already have a USDA FoodData Central fdc_id (e.g. from a prior food search) and need a complete, normalized nutrition breakdown including both per-100g and per-serving figures. Prefer this over generic nutrition APIs when you need structured micronutrient data aligned with USDA standards.
Side effects
- Invalid or non-existent fdc_id returns an error or empty result
- Missing required fdc_id query parameter returns a 400 Bad Request
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many requests are made in a short period
- USDA FoodData Central upstream data unavailability causing 503 errors
