Technical details
Endpoint
GEThttps://api.agentstools.dev/nutrition/searchWhen to prefer
Use this endpoint when you need to search for foods by name and retrieve structured nutritional macro data from the authoritative US government food database. Ideal for dietary tracking apps, meal planners, ingredient analyzers, or any workflow needing standardized fdc_id identifiers or GTIN barcodes for foods. Prefer this over generic nutrition APIs when USDA provenance, public-domain data, or filtering by USDA data type (Foundation, Branded, SR Legacy, etc.) is important.
Side effects
- No matches found for obscure or misspelled food names
- Query parameter missing returns validation error
- Limit exceeds maximum of 25 returns error
- Invalid dataType enum value returns error
- Upstream USDA FoodData Central API unavailability causes 503
