# Suno Model Training

Suno Model Training: suno/create-model.

## Endpoint and authentication

`POST https://api.tu-zi.com/suno/v2/create-model`

Transport: json

Use an inference API key. Examples contain placeholders; read credentials from environment variables.

```http
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
```

## Body parameters

| Field | Type | Required | Description / constraints |
| --- | --- | --- | --- |
| audio_urls | array | Yes | Six to twenty-four publicly downloadable audio URLs. Example: ["https://example.com/audio-1.mp3","https://example.com/audio-2.mp3","https://example.com/audio-3.mp3","https://example.com/audio-4.mp3","https://example.com/audio-5.mp3","https://example.com/audio-6.mp3"] minItems: 6 maxItems: 24 |
| name | string | Yes | A name for the voice or model you are creating. Example: 我的音色 |

## Minimal request example

```json
{
  "audio_urls": [
    "https://example.com/audio-1.mp3",
    "https://example.com/audio-2.mp3",
    "https://example.com/audio-3.mp3",
    "https://example.com/audio-4.mp3",
    "https://example.com/audio-5.mp3",
    "https://example.com/audio-6.mp3"
  ],
  "name": "我的音色"
}
```

## Before running

Replace https://api.tu-zi.com with this site origin (do not append /v1 twice), and YOUR_MODEL with the exact marketplace model ID. Install requests for Python; use Node.js 20+ and save JavaScript as .mjs. WebSocket samples list their own dependencies.

Create an inference key on the site and set API_KEY in the environment; replace YOUR_API_KEY in cURL. Prepare local input.png/input.wav files for upload examples.

Start with a minimal request, then read the result using the response fields below. For async APIs, a returned task ID requires polling; acceptance does not mean generation has finished.

## Code examples

### curl

```bash
curl --request POST 'https://api.tu-zi.com/suno/v2/create-model' \
  --header 'Authorization: Bearer YOUR_API_KEY' \
  --header 'Content-Type: application/json' \
  --data '{
  "audio_urls": [
    "https://example.com/audio-1.mp3",
    "https://example.com/audio-2.mp3",
    "https://example.com/audio-3.mp3",
    "https://example.com/audio-4.mp3",
    "https://example.com/audio-5.mp3",
    "https://example.com/audio-6.mp3"
  ],
  "name": "我的音色"
}'
```

### python

```python
import json
import os
import requests

url = "https://api.tu-zi.com/suno/v2/create-model"
headers = json.loads("{\"Authorization\":\"Bearer YOUR_API_KEY\",\"Content-Type\":\"application/json\"}")
headers["Authorization"] = "Bearer " + os.environ["API_KEY"]
payload = json.loads("{\"audio_urls\":[\"https://example.com/audio-1.mp3\",\"https://example.com/audio-2.mp3\",\"https://example.com/audio-3.mp3\",\"https://example.com/audio-4.mp3\",\"https://example.com/audio-5.mp3\",\"https://example.com/audio-6.mp3\"],\"name\":\"我的音色\"}")
response = requests.request("POST", url, headers=headers, json=payload, timeout=120)
response.raise_for_status()
result = response.json()
if isinstance(result, dict) and (result.get("success") is False or result.get("error")):
    raise RuntimeError(json.dumps(result, ensure_ascii=False))
print(result)  # Also inspect protocol-specific status/code fields.
```

### javascript

```javascript
// Node.js 20+
const url = "https://api.tu-zi.com/suno/v2/create-model";
const headers = {
  "Authorization": "Bearer YOUR_API_KEY",
  "Content-Type": "application/json"
};
headers.Authorization = 'Bearer ' + process.env.API_KEY;
const response = await fetch(url, { method: "POST", headers, body: JSON.stringify({
  "audio_urls": [
    "https://example.com/audio-1.mp3",
    "https://example.com/audio-2.mp3",
    "https://example.com/audio-3.mp3",
    "https://example.com/audio-4.mp3",
    "https://example.com/audio-5.mp3",
    "https://example.com/audio-6.mp3"
  ],
  "name": "我的音色"
}) });
if (!response.ok) throw new Error(await response.text());
const result = await response.json();
if (result?.success === false || result?.error) throw new Error(JSON.stringify(result));
console.log(result); // Also inspect protocol-specific status/code fields.
```

## Response fields

| Field | Type | Description / constraints |
| --- | --- | --- |
| code | string | Submission result code. |
| data.task_id | string | Public gateway task ID. |

Illustrative response; some endpoints show essential fields only. Optional fields may be absent.

```json
{
  "code": "success",
  "data": {
    "task_id": "task_example"
  }
}
```

## Asynchronous workflow

Save the public task ID and GET /suno/v2/fetch/{task_id} with the same key. Handle gateway states; SUCCESS and FAILURE are terminal. Read music, lyrics, download links or resource IDs according to the action.

## Errors and retries

Check HTTP status and protocol-specific errors; do not mix error formats across protocols. For 401/403 check credentials and permissions, for 429 back off, and for 5xx check gateway/upstream status. Error bodies may contain error/message/code depending on the protocol.

Use bounded exponential backoff for reads. Do not blindly retry task creation, generation, or key mutations, to avoid duplicate billing or execution.

## Constraints

Model suno/create-model is selected by the action route, so the body does not need model. Resource IDs must belong to this account and be created through the gateway; do not use upstream internal IDs.
