### Python Error Handling Example

Source: https://docs.musicgpt.com/api-documentation/utilities/error

A practical Python code example demonstrating how to handle various HTTP status codes returned by the MusicGPT API, including success, client errors, and server errors.

```APIDOC
## How to Handle Errors in Your Code (Python Example)

This example illustrates how to implement error handling logic when making requests to the MusicGPT API using Python.

### Python Code Snippet

```python
import requests

url = "https://api.musicgpt.com/data"
headers = {
    "Authorization": "Bearer <your_api_key>"
}

try:
    response = requests.get(url, headers=headers)
    response.raise_for_status()  # Raise an exception for bad status codes (4xx or 5xx)

    if response.status_code == 200:
        print("Request successful:", response.json())
    # Additional specific checks can be added here if needed for particular 2xx codes

except requests.exceptions.HTTPError as e:
    status_code = e.response.status_code
    if status_code == 400:
        print(f"Error {status_code}: Bad Request. Please check your input parameters.")
    elif status_code == 402:
        print(f"Error {status_code}: Payment Required. Please check your account balance or payment method.")
    elif status_code == 403:
        print(f"Error {status_code}: Forbidden. Check your API key permissions.")
    elif status_code == 404:
        print(f"Error {status_code}: Not Found. The requested resource does not exist.")
    elif status_code == 409:
        print(f"Error {status_code}: Conflict. There is a conflict with the resource state.")
    elif status_code == 422:
        print(f"Error {status_code}: Unprocessable Entity. Review the request body for validation errors.")
    elif status_code == 429:
        print(f"Error {status_code}: Rate Limit Exceeded. Please try again later.")
    elif status_code >= 500:
        print(f"Error {status_code}: Internal Server Error. Please try again later or contact support.")
    else:
        print(f"An unexpected HTTP error occurred: {status_code} - {e.response.text}")
except requests.exceptions.RequestException as e:
    print(f"A network or request-related error occurred: {e}")
```

### Transcribe Audio using Go

Source: https://docs.musicgpt.com/api-documentation/conversions/audiotranscription

This Go code snippet illustrates how to interact with the MusicGPT API for audio transcription. It covers both transcribing from a URL and uploading a local audio file. The code uses the `net/http` package for requests and `mime/multipart` for file uploads, requiring an API key for authentication. Error handling is minimal in this example.

```Go
package main

import (
	"bytes"
	"fmt"
	"io"
	"mime/multipart"
	"net/http"
	"os"
	"strings"
)

func main() {
	url := "https://api.musicgpt.com/api/public/v1/audio_transcribe"
	apiKey := "<<<api key>>>"

	// Option 1: URL
	payload := "audio_url=https://example.com/audio.mp3&language=en&translate=true&transcription_format=srt&word_timestamps=true"
	req, _ := http.NewRequest("POST", url, strings.NewReader(payload))
	req.Header.Add("Authorization", apiKey)
	res, _ := http.DefaultClient.Do(req)
	defer res.Body.Close()
	body, _ := io.ReadAll(res.Body)
	fmt.Println(string(body))

	// Option 2: File Upload
	file, _ := os.Open("audio.mp3")
	defer file.Close()
	bodyBuf := &bytes.Buffer{}
	writer := multipart.NewWriter(bodyBuf)
	writer.WriteField("language", "en")
	writer.WriteField("translate", "false")
	writer.WriteField("transcription_format", "plain_text")
	writer.WriteField("word_timestamps", "true")
	part, _ := writer.CreateFormFile("audio_file", "audio.mp3")
	io.Copy(part, file)
	writer.Close()

	req, _ = http.NewRequest("POST", url, bodyBuf)
	req.Header.Add("Authorization", apiKey)
	req.Header.Add("Content-Type", writer.FormDataContentType())
	res, _ = http.DefaultClient.Do(req)
	defer res.Body.Close()
	body, _ = io.ReadAll(res.Body)
	fmt.Println(string(body))
}
```

### Webhook Integration Guide

Source: https://docs.musicgpt.com/api-documentation/index/webhook

This section outlines the process of using webhooks for Musicgpt asynchronous tasks. It covers how to set the webhook URL, what to expect in the POST request from Musicgpt upon task completion, and how to handle the incoming payload.

```APIDOC
## Webhook Integration

Webhooks allow Musicgpt to notify your application the moment an asynchronous task (like music generation, voice cloning, or instrumental extraction) is completed. This eliminates the need for constant polling of the API.

### How It Works

1.  **Set the `webhook_url`**: Provide your server's URL when submitting a conversion request.
2.  **Receive POST Request**: Musicgpt will send a POST request to your specified `webhook_url` when the task is finished.
3.  **Process Payload**: Your server can parse the received JSON payload to access details like the audio URL and task status.

### Sample Webhook Payload

When a task is completed, Musicgpt sends a JSON payload containing:

*   **`task_id`** (string): The unique identifier for the task.
*   **`status`** (string): The completion status (e.g., "COMPLETED").
*   **`status_msg`** (string): A message indicating the status.
*   **`conversion_type`** (string): The type of conversion performed (e.g., "MUSIC_AI").
*   **`audio_url`** (string): The URL to the generated audio file.
*   **`title`** (string): The title of the generated content.
*   **`conversion_cost`** (number): The cost associated with the conversion.
*   **`createdAt`** (string): The timestamp when the task was created.
*   **`updatedAt`** (string): The timestamp when the task was last updated.

**Example Payload:**

```json
{
  "task_id": "12345678-abcd-1234-efgh-567890abcdef",
  "status": "COMPLETED",
  "status_msg": "Conversion successful",
  "conversion_type": "MUSIC_AI",
  "audio_url": "https://musicgpt.s3.amazonaws.com/audiofile.mp3",
  "title": "Generated Song",
  "conversion_cost": 1.25,
  "createdAt": "2025-01-01T12:00:00Z",
  "updatedAt": "2025-01-01T12:05:00Z"
}
```

### Preliminary Response

Upon initiating a conversion request, Musicgpt provides an immediate preliminary response confirming the task acceptance. This response includes:

*   **`success`** (boolean): Indicates if the task initiation was successful.
*   **`task_id`** (string): A unique ID for tracking the task.

**Example Preliminary Response:**

```json
{
  "success": true,
  "task_id": "12345678-abcd-1234-efgh-567890abcdef"
}
```

### Alternative: Get Conversion by ID

If you cannot use webhooks (e.g., running code on a client device or lacking a public server), you can manually check the conversion status using the "Get Conversion by ID" endpoint. Refer to `/api-documentation/endpoint/CheckStatus` for details.
```

--------------------------------

### Extend Task API - Successful Response Example

Source: https://docs.musicgpt.com/api-documentation/conversions/extend

This example demonstrates the JSON response structure for a successfully initiated extend task. It includes a success status, a confirmation message, task and conversion identifiers, estimated processing time, and a credit estimate.

```json
{
  "success": true,
  "message": "Extend request submitted successfully",
  "task_id": "task-extend-789",
  "conversion_id_1": "extend-a1b2",
  "conversion_id_2": "extend-c3d4",
  "eta": 38,
  "credit_estimate": 42
}
```

### Inpaint Audio with File Upload using Python - MusicGPT API

Source: https://docs.musicgpt.com/api-documentation/endpoint/inpaint

This code example shows how to perform audio inpainting using the MusicGPT API by uploading an audio file directly. It includes setting up the request headers with an API key, defining the inpainting parameters, and attaching the audio file in binary mode. An optional webhook URL can be provided for asynchronous results.

```Python
import requests


url = "https://api.musicgpt.com/api/public/v1/inpaint"
headers = {"Authorization": "<API_KEY>"}
data = {
  "prompt": "Add a soft guitar solo here",
  "replace_start_at": 12.5,
  "replace_end_at": 20.0,
  "lyrics": "This is where my story begins",
  "gender": "male",
  "webhook_url": "https://example.com/webhook"
}


# Option 2: File Upload

with open("song.mp3", "rb") as f:
    files = {"audio_file": f}
    response = requests.post(url, headers=headers, data=data,
files=files)


# print(response.json())

```

    "voice_id": "<string>",
    "remove_background": "<int>",
    "pitch": "<int>",
    "webhook_url": "<string>"
}

# For file upload instead of URL:

# files = {'audio_file': open('filepath', 'rb')}

headers = {
    "Authorization": "<API Key>"
}

response = requests.post(url, data=payload, headers=headers)

# For file upload:

# response = requests.post(url, data=payload, files=files,
headers=headers)


print(response.text)
```

```PHP
<?php

$url = "https://api.musicgpt.com/api/public/v1/VoiceChanger";
$apiKey = "<API_KEY>";


// For URL-based processing
$data = [
    "audio_url" => "<AUDIO_URL>",
    "voice_id" => "<VOICE_ID>",
    "remove_background" => 0, // 0 or 1
    "pitch" => 0, // -12 to +12
    "webhook_url" => "<WEBHOOK_URL>"
];


// For file upload (uncomment and replace)

// $data = ["voice_id" => "<VOICE_ID>"];

// $file = new CURLFile('path/to/audio.wav', 'audio/wav',
'audio_file');


$headers = [
    "Authorization: " . $apiKey
];


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

// For file upload:

// curl_setopt($ch, CURLOPT_POSTFIELDS, array_merge($data, ['audio_file' => $file]));

curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);


$response = curl_exec($ch);
curl_close($ch);

### Call Voice Changer API with File Upload (Java)

Source: https://docs.musicgpt.com/api-documentation/endpoint/voicetovoice

This Java code example demonstrates how to upload an audio file using the MusicGPT Voice Changer API with OkHttp. It sets up a multipart request including the audio file and other necessary parameters, with authentication handled via an API key. The API response is then printed.

```Java
import okhttp3.*;

import java.io.File;
import java.io.IOException;

public class VoiceChanger {
    public static void main(String[] args) throws IOException {
        String url = "https://api.musicgpt.com/api/public/v1/VoiceChanger";
        String apiKey = "<API_KEY>";

        // For URL-based processing
        /*
        RequestBody requestBody = new FormBody.Builder()
                .add("audio_url", "<AUDIO_URL>")
                .add("voice_id", "<VOICE_ID>")
                .add("remove_background", "0")
                .add("pitch", "0")
                .add("webhook_url", "<WEBHOOK_URL>")
                .build();
        */

        // For file upload (uncomment and replace)
        File audioFile = new File("audio.wav");
        RequestBody requestBody = new MultipartBody.Builder()
                .setType(MultipartBody.FORM)
                .addFormDataPart("voice_id", "<VOICE_ID>")
                .addFormDataPart("audio_file", "audio.wav",
                        RequestBody.create(audioFile, MediaType.parse("audio/wav")),
                        RequestBody.create(audioFile, MediaType.parse("audio/wav")))
                .build();

        Request request = new Request.Builder()
                .url(url)
                .post(requestBody)
                .header("Authorization", apiKey)
                .build();

        OkHttpClient client = new OkHttpClient();
        try (Response response = client.newCall(request).execute()) {
            System.out.println(response.body().string());
        }
    }
}
```

### Initiate Noise Removal via URL - Go

Source: https://docs.musicgpt.com/api-documentation/conversions/denoise

This Go code snippet demonstrates how to initiate the noise removal process by providing an audio file URL. It sends a POST request to the `/api/public/v1/denoise` endpoint with the audio URL and an optional webhook URL. The API key must be included in the Authorization header. The response will contain a task ID for tracking the conversion.

```Go
package main

import (
	"bytes"
	"fmt"
	"io"
	"mime/multipart"
	"net/http"
	"os"
	"strings"
)

func main() {
	url := "https://api.musicgpt.com/api/public/v1/denoise"
	headers := map[string]string{
		"Authorization": "<<<api key>>>"
	}

	// Option 1: URL
	data := "audio_url=https://example.com/audio.m4a&webhook_url="
	req, _ := http.NewRequest("POST", url, strings.NewReader(data))
	for k, v := range headers {
		req.Header.Add(k, v)
	}
	res, _ := http.DefaultClient.Do(req)
	defer res.Body.Close()
	body, _ := io.ReadAll(res.Body)
	fmt.Println(string(body))

	// Option 2: File Upload
	file, _ := os.Open("audio.m4a")
	defer file.Close()
	bodyBuf := &bytes.Buffer{}
	writer := multipart.NewWriter(bodyBuf)
	_ = writer.WriteField("webhook_url", "https://www.test.requestcatcher.com/test")
	part, _ := writer.CreateFormFile("audio_file", "audio.m4a")
	io.Copy(part, file)
	writer.Close()

	req, _ = http.NewRequest("POST", url, bodyBuf)
	req.Header.Add("Authorization", "<<<api key>>>")
	req.Header.Add("Content-Type", writer.FormDataContentType())
	res, _ = http.DefaultClient.Do(req)
	defer res.Body.Close()
	body, _ = io.ReadAll(res.Body)
	fmt.Println(string(body))
}
```

```go
package main

import (
	"bytes"
	"fmt"
	"io"
	"net/http"
	"strings"
)

func main() {
