• usda_list_nutrients

  Look up the FDC nutrient reference table — all tracked nutrients with their numeric IDs, names, SR reference numbers, units, and categories. Use to resolve a nutrient name (e.g. "vitamin C") to its FDC ID (1162) before passing it to the nutrients[] filter on other tools. Filter…

• usda_search_foods

  Search USDA FoodData Central foods by keyword. Returns matching foods with FDC IDs and a preview of key nutrients (energy, protein, fat, carbs — not guaranteed complete). Use the returned fdcId with usda_get_food for the full nutrient profile, or usda_compare_foods for…
