How this service works
USDA FoodData Central nutrition data API with x402 micropayments. Search foods, get full nutrition profiles, and compare multiple foods side-by-side.

Technical details
Endpoint
GEThttps://food.memoryapi.org/x402/food/searchWhen to prefer
Use this endpoint when you need to search for foods by name and get their USDA FDC IDs and macronutrient data. Prefer this over the sibling full-nutrition endpoint when you don't yet know the FDC ID and need to discover matching foods first. This is the discovery step before fetching a full nutrition profile.
Side effects
- No results found for the given food name query
- Invalid or empty search query returns error
- Rate limiting or payment failure via x402 protocol
- Network timeout from USDA FoodData Central upstream
