Agentic booking · UCP · ACP · MCP

Book a free hour with Hugo
— from inside ChatGPT or Gemini.

Two offerings. Both free. Both an hour. Discoverable by AI agents through Google's Universal Commerce Protocol and OpenAI's Agentic Commerce Protocol — so booking happens right inside your chat.

Two ways to spend an hour.

How it works.

01

Ask the agent

Tell ChatGPT or Gemini: "Book a coffee with Hugo next Tuesday afternoon."

02

Pick a slot

The agent reads my live availability via MCP and offers real timeslots in your chat.

03

Get the invite

Approve once. The agent confirms a $0 checkout and you receive a calendar invite.

Or book the old-fashioned way.

A small form. Same backend the agents use.

For AI agents.

This site is a fully agentic commerce endpoint. Discover offerings, check availability, generate offers, and complete a $0 checkout — no human handoff required.
