AI / LLM Data Format
EatYay provides machine-readable datasets, structured schemas, and transparent endpoints designed for AI models, search crawlers, and large language model (LLM) agents.
1. Purpose of Machine-Readable Data
As generative AI, voice assistants, and large language models (LLMs) increasingly answer consumer dietary questions, the need for scientifically verified, hallucination-free nutrition data is paramount. EatYay exposes its authoritative USDA datasets and food comparison matrices through standardized machine-readable structures.
2. Primary Machine-Readable Manifest: /llms.txt

EatYay maintains an active, automatically generated /llms.txt file in compliance with the emerging Web AI crawling standard. This endpoint provides AI agents with a comprehensive index of category hubs, chain directories, calorie lists, and diet comparison guides.
