# QR codes to share your profile. No more spelling it out.

Your WhatsApp, your LinkedIn, your calendar, your website or your contact card, each as a big QR, on a page you install on your phone. Show the right one and they scan.

**Free for a limited time.** Everything in Pro, free during the launch. What you build now keeps working.

## How it works

You claim your address, add your QRs and install it on your phone. On the web, or by asking ChatGPT or Claude.

- **Works without signal**: Once opened it stays on your phone. In the event's basement too.
- **Bright mode**: One tap and the screen stays on while people scan.
- **One QR per screen**: Large, with each network's mark. Nobody scans the wrong one.
- **They install nothing**: They scan it with the camera and it opens your WhatsApp, your profile or your site.

- “Set up my page at the address “martin” with my name, Martin Leigh.” Your address is yours and the page is ready for QRs.
- “Add my WhatsApp with the message “Hi! We met at the conference”.” Whoever scans it opens a chat with you, that message already written.
- “Add my LinkedIn and put it first.” The first tab is what people see when your page opens.
- “Add a contact card with my company and phone.” When scanned, the phone offers to save you to its contacts, offline.

## Also from ChatGPT or Claude

Connect your assistant and change your page by talking: “add my Instagram”, “change the WhatsApp message”. You sign in with your email once.

MCP server URL (Streamable HTTP, OAuth): `https://qrzoo.com/mcp`

The same URL works for all of them. When you add it, the assistant sends you to sign in with your email and to allow access; that's all.

### ChatGPT (Apps & Connectors)

1. Settings › Apps & Connectors › add a connector with the URL above.
2. Sign in with your email (link or code) and choose Allow.
3. Ask “show me my page”. It shows up in the chat.

### Claude (Web · Desktop · Cowork)

1. Settings › Connectors › Add custom connector, with the URL above.
2. Sign in with your email and choose Allow.
3. Ask “add my LinkedIn to my page”. Claude shows it in the chat.

### Claude Code, Cursor and scripts

1. `claude mcp add --transport http qrzoo https://qrzoo.com/mcp`
2. Cursor and other clients: add an MCP server with HTTP transport and the same URL.
3. A script: create an API key in your account and send `Authorization: Bearer sk_qrzoo_…` to the API.

### Your own script

The same page through the HTTP API, with an API key from your account.

```http
POST /api/items
Authorization: Bearer sk_qrzoo_…
{"kind":"linkedin",
 "value":"linkedin.com/in/martin-leigh"}
```

## Questions

### Does the person scanning need an app?

No. They scan with the phone’s camera and it opens WhatsApp, your site or whatever link it is.

### Is it an app from the store?

No need: it is a web page you install from the browser, and it sits on your home screen with your icon.

### Does it work without internet?

Yes. Opened once, it stays on your phone. Showing a QR needs no signal; opening the link does, on the other phone.

### What is the contact card?

A QR with your name, company, phone and email inside. The phone offers to save you to contacts.

### How much is it?

Nothing during the launch, with everything in Pro. Later, Pro is a one-time USD 1.99 and what you build now keeps working.

### How do I sign in?

No password. You sign in with your email: we send a link and an 8-digit code.

### Can I change my address?

Yes. The old one stays reserved for you for 90 days, so nobody takes the QRs you already shared.
