How this service works
Structured nutrition data for agents, paid per request with x402 v2
Output
A structured list of food items (up to the requested limit) with detailed nutrition data per item, including macronutrients (calories, protein, fat, carbohydrates), micronutrients, serving sizes, and food source metadata (e.g., Foundation, SR Legacy, Survey FNDDS, or Branded category).
Example use cases
Recipe ingredient nutrition breakdown
“Get me the nutritional info for cooked brown rice from the USDA Foundation and SR Legacy databases, up to 3 results, so I can calculate macros for my recipe.”
Branded product nutrition lookup
“Find nutrition facts for Cheerios from the Branded food database — give me up to 10 results — I need calories, carbs, and protein per serving.”
Dietary planning macro check
“Pull structured nutrition data for chicken breast from the USDA Survey FNDDS database, limit to 5 results, so I can track my protein intake for the day.”
Technical details
Endpoint
POSThttps://x402.srch.best/nutritionWhen to prefer
Choose this endpoint when you need structured, USDA-sourced nutrition data for a specific food query and want to filter by food database type (Foundation, SR Legacy, Survey FNDDS, or Branded). It is ideal for agent workflows that need machine-readable nutrition facts per-request at low cost ($0.001 USDC) without managing a full USDA API integration. Prefer this over general web search when you need clean, schema-consistent nutrition output rather than scraped or unstructured data.
Side effects
- Query string too short (under 2 chars) or too long (over 200 chars) returns validation error
- Limit outside 1–20 range rejected with parameter error
- Invalid dataType enum value causes request failure
- Payment not included or insufficient USDC causes 402 Payment Required response
- No matching foods found returns empty result set
- Network or provider timeout returns error response
