A publicly accessible URL that serves machine-readable JSON-LD structured data for a website’s core content or facts. By exposing your organization’s key entities, attributes, and relationships through a dedicated JSON-LD endpoint (often at a path like /facts.jsonld or /llms.jsonld), you create a “public fact API” that AI systems—search engines, chatbots, and LLMs—can crawl, index, and cite directly. This ensures your most important brand and product information is ingested in a consistent, schema-driven format, boosting the likelihood of verbatim citations and rich answer snippets across AI-powered platforms.
