## When to prefer this

Choose this endpoint when you need authoritative USDA-sourced nutrition data for raw foods or branded products, especially when you need a comprehensive panel of nutrients (macros + micronutrients + minerals) in one call. Prefer this over generic web scraping for reliable, structured nutritional data. It is ideal for diet tracking, meal planning, recipe analysis, or any agent workflow that needs to enrich food items with validated nutritional information.

## Known failure modes

- No matching food found for the query string — returns empty results or 404
- Ambiguous query matches too many products — caller should narrow query or use limit parameter
- Branded product not in USDA FoodData Central database — may return generic or no result
- Query parameter 'q' missing — returns validation error
- Rate limit or payment failure — returns 402 or 429 status
