USDA Food Data Central (BYOK) lets an AI assistant read your own USDA Food Data Central data through the USDA Food Data Central API with a key you supply (api.data.gov API key for FoodData Central). Read-only: 6 tools (search_foods, search_branded_foods, get_food, get_food_nutrients, get_foods, list_foods). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to api.nal.usda.gov. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by USDA Food Data Central. USDA Food Data Central and its logos are trademarks of their owners and are used only to say which service the connector works with.
Sources: Live from the USDA Food Data Central API (api.nal.usda.gov) with a BYOK key; documentation: https://fdc.nal.usda.gov/api-guide. Endpoints checked against that documentation on 2026-10-16.
