Web4 Page is the webpage for AI. IRL is the URL for AI.

A Web4 Page gives AI the ability to read, discover, write, and act on behalf of any entity on the internet. Without one, AI cannot find you, cite you, or do business with you.

The Framework

Web4 Page Framework

A new AI-native webpage that enables human-to-agent and agent-to-agent interactions. Four capability zones — from being understood by AI to being operated by AI.

OPENAPIAction capability
MCP ENDPOINTSReal-time operation

Step 1 — READ

AI understands who you are

Add your business name, description, products, and llms.txt grounding text. Go from invisible to cited in 60 seconds.

llms.txtgrounding60 sec

Step 2 — DISCOVER

AI can find and cite you

Auto-generates JSON-LD from your profile. Side B machine-readable. Entity Score calculated. AI models can now discover and cite your entity.

Step 3 — WRITE

AI can transact with you

Link or generate an OpenAPI spec. Now AI can book appointments, place orders, check inventory — and financial institutions declare their AI-facing API for CFPB compliance.

Step 4 — ACT

AI agents operate with you

Register an MCP endpoint. AI agents can now autonomously operate your business in real time — the full agentic web, with your entity at the center.
