Example use cases
Macro tracking for meal planning

Technical details
Endpoint
GEThttps://fittings.sh/v1/usda/food-searchWhen to prefer
Use this endpoint when you need structured nutritional data (calories, protein, fat, carbs, serving size) for a food item by name, especially when you need USDA-authoritative data with FDC IDs for cross-referencing. Prefer this over generic nutrition APIs when you need data sourced directly from the USDA FoodData Central and need to filter by specific data types like Foundation or Branded foods.
Side effects
- No results returned for obscure or misspelled food names
- Branded food data may be incomplete or outdated
- Query returns too many ambiguous results when search term is too broad
- Invalid dataType filter value causes query failure
- Limit parameter outside 1–50 range may cause an error
