# PurAI.js

PurAI.js is a simple JavaScript/TypeScript library that allows you to interact with the PurAI API.

## Installation

```bash
npm install purai.js
```

## Usage

### Setup

First, you need to get an API key from the [PurAI Discord server](https://discord.gg/purlabs-1117511140440821852).

```js
const { PurAi, ApiStyle } = require('purai.js');

const purAi = new PurAi('your-api-key', {
    // apiStyle: ApiStyle.OpenAi // Allows you to interact with the PurAI API using the OpenAI style
});
```

### See the available models

```js
await purAi.models();
```

### Generate an image

> [!WARNING]
> Generally the images are expired after 5 minutes, depending on the provider.

```js
await purAi.generateImage('dalle-3', "Imagine a fluffy, ginger tabby cat lounging lazily in a patch of sunlight filtering through a window. Its fur glows with a warm, golden hue, accentuating the soft stripes that run along its back. The cat's eyes are a deep, amber color, reflecting the tranquility of its surroundings. It's curled up elegantly, with its tail neatly wrapped around its paws, exuding a sense of contentment and peace.");
