AI Endpoint
A JSON file served at a predictable URL on a website that gives AI systems direct, machine-readable access to site identity, content catalog, or operational data.
Also known as: AI API endpoint, machine-readable endpoint
AI endpoints are structured JSON files served at predictable paths (e.g., /ai/llm.json, /ai/catalog.json, /ai/health.json) that AI systems, crawlers, and agents can request directly.
They function like a lightweight API for a website ... no database required, no authentication needed, just static JSON that describes what the site is, what it covers, and what content is available.
Common AI endpoints include: llm.json (site identity and topic coverage), ai-sitemap.json (content index by type), catalog.json (full content catalog with metadata), and health.json (operational status).
