Endpoint
GEThttps://agentrxi.com/v1/nutrition?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, authoritative USDA nutrition data for foods or branded products, including macros and micronutrients. Prefer it over general web search when you need machine-readable nutrition facts for logging, analysis, or dietary planning. Best when the user asks about calories, protein, fat, carbs, sugar, sodium, fiber, or minerals for a specific food item.
Side effects
- Food not found in USDA database — returns empty results or minimal matches
- Ambiguous food name returns unrelated results — refine query for better accuracy
- Rate limit or payment failure — 402 response if USDC payment not attached
- Invalid or missing query parameter — 400 bad request
- Branded product not in USDA database — may return no results or generic equivalent
