Technical details
Endpoint
GEThttps://api.agentstools.dev/nutrition/foodWhen to prefer
Use this endpoint when you already have a USDA FoodData Central fdc_id (e.g. from a prior search) and need the complete, normalized nutrition breakdown including both per-100g and per-serving figures. Prefer this over generic nutrition APIs when USDA data fidelity and micronutrient completeness matter, or when building calorie trackers, meal planners, or dietary analysis tools.
Side effects
- fdc_id not found in USDA FoodData Central — returns 404 or empty result
- fdc_id is invalid or non-integer — returns validation error
- food item exists but has incomplete nutrient data in USDA database — partial profile returned
- rate limiting or payment failure — returns 402 or 429
- USDA upstream data unavailable — returns 503
