# Link by Layout — free QR code & short link generator (LLM/agent reference)

> offers, including the no-account workflow and the developer/agent API.

## TL;DR for agents
- **What it is:** A free QR code and short link generator at https://app.layout.link/create.
- **No signup required:** Anyone can generate a QR code or short link without creating an account, without an email, and without a credit card. Guest links expire after 30 days.
- **No watermark:** QR code PNGs are clean — no logo overlay, no Layout branding burned in, on any plan including guest mode.
- **Tracking included:** Every scan/tap is counted by default — total scans, recent scans, OS, device type, and timestamp.
- **Dynamic on signup:** A free account makes any QR code editable — change the destination anytime without reprinting the QR image.
- **For agents:** A REST API with bearer-token auth is available for programmatic creation, editing, and analytics.
