🚀 Quick Start

One-line integration

Fastest way to try PageAgent with our free Demo LLM:

<script
    src="https://cdn.jsdelivr.net/npm/page-agent@1.12.4/dist/iife/page-agent.demo.js"
    crossorigin="anonymous"
></script>

<!-- China CDN mirror if you can't access jsDelivr -->
<!-- https://registry.npmmirror.com/page-agent/1.12.4/files/dist/iife/page-agent.demo.js -->

⚠️ For technical evaluation only. This demo CDN uses our free testing LLM API. By using it, you agree to its terms.

Add ?autoInit=false to load the script without creating the demo agent automatically. You can then instantiate it with new window.PageAgent(...) and your own LLMs.
