Free, Unlimited Aion Labs API
On this page
This tutorial will show you how to use Puter.js to access Aion Labs models, including Aion 3.0, Aion 3.0 Mini, Aion 2.0 and Aion RP 1.0 completely free, without any API keys.
Puter.js uses the User-Pays model, where users of your application cover their own AI costs. This means you as a developer don't pay anything for your users' usage, making your app practically free to run. You can scale to unlimited users and pay nothing for the AI or server usage.
To use Puter.js, import our npm module in your project:
// npm install @heyputer/puter.js
import { puter } from '@heyputer/puter.js';
Or alternatively, add our script via CDN if you are working directly with HTML, simply add it to the <head> or <body> section of your code:
<script src="https://js.puter.com/v2/"></script>
Nothing else is required to start using Puter.js for free access to Aion Labs models and capabilities.
