# Real-Esrgan API Usage Guide

## Introduction

This document will guide developers on how to use the aonweb library to call the Real-Esrgan API, which is used for voice cloning and text-to-speech conversion.

## Prerequisites

- Node.js environment
- `aonweb` library installed
- Valid Aonet APPID

## Basic Usage

### 1. Import Required Modules

```js
import { AI, AIOptions } from 'aonweb';
```

### 2. Initialize AI Instance

```js
const ai_options = new AIOptions({
    appId: 'your_app_id_here',
    dev_mode: true
});

const aonweb = new AI(ai_options);
```

### 3. Prepare Input Data Example

```js
const data = {
   input:{
    "image": "https://replicate.delivery/pbxt/Ing7Fa4YMk6YtcoG1YZnaK3UwbgDB5guRc5M2dEjV6ODNLMl/cat.jpg",
    "scale": 2,
    "face_enhance": false
  }
};
```

### 4. Call the AI Model

```js
const price = 8; // Cost of the AI call
try {
    const response = await aonweb.prediction("/predictions/ai/real-esrgan", data, price);
    // Handle response
    console.log("Real-Esrgan result:", response);
} catch (error) {
    // Error handling
    console.error("Error generating :", error);
}
```

### Parameter Description

- `image` String,Provide the image file that needs optimization
- `scale` Number,Factor to scale image by
- `face_enhance` Boolean,Run GFPGAN face enhancement along with upscaling

### Notes

- Ensure that the provided audio URL is publicly accessible and of good quality to achieve the best cloning effect.
- The API may take some time to process the input and generate the result, consider implementing appropriate wait or loading states.
- Handle possible errors, such as network issues, invalid input, or API limitations.
- Adhere to the terms of use and privacy regulations, especially when handling voice samples of others.

### Example Response

The API response will contain the URL of the generated cloned voice or other relevant information. Parse and use the response data according to the actual API documentation.
