# Mureka 9.5 Song Generation API

> با کنترل سبک، صدا و ملودی، از پرامپت یا متن ترانه آهنگ‌های دارای آواز تولید می‌کند

برای تبدیل متن ترانه به آهنگ از `lyrics` (حداکثر 5000 کاراکتر)، یا برای تبدیل پرامپت به آهنگ از `prompt` (حداکثر 2000 کاراکتر) و `styles` استفاده کنید. گزینه‌ها شامل `gender`، `reference_id`، `vocal_id` و `melody_id` هستند. فهرست `model` شامل mureka-7.6، mureka-o2، mureka-8، mureka-9 و mureka-9.5 (پیش‌فرض) است. صوت، مدت و یک `song_id` برمی‌گرداند.

- Model id: `mureka/api/generate/song`
- Made by: Mureka
- Category: Text to Music
- Output: audio
- Price per run: from $0.45 / run (cheapest run $0.45 (450 API credits))
- Run: `POST https://api.doitong.com/v1/run/mureka/api/generate/song`
- Quote: `POST https://api.doitong.com/v1/quote/mureka/api/generate/song`
- Docs page: https://doitong.com/fa/developers/models/mureka/api/generate/song

## Pricing

Price: **from $0.45 / run** (the lowest tier; the quote prices your exact input). Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

Price by tier:

- mureka-7.6: $0.45 / run
- mureka-o2: $0.45 / run
- mureka-8: $0.45 / run
- mureka-9: $0.45 / run
- mureka-9.5: $0.75 / run

The full example input below costs $0.75 = 750 API credits (1 run × $0.75 (mureka-9.5)).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/mureka/api/generate/song` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `model` |  | enum (string) | no | `mureka-9.5` | `mureka-7.6`, `mureka-o2`, `mureka-8`, `mureka-9`, `mureka-9.5` | مدل مورد استفاده برای تولید آهنگ. |
| `lyrics` |  | string \| null | no |  | 1 – 5000 characters | متن خوانده‌شده برای تولید آهنگ از روی شعر، با حداکثر طول 5,000 نویسه. برای تولید آهنگ از روی پرامپت، به‌جای lyrics، پرامپت را ارسال کنید. |
| `styles` |  | array of enum (string) \| null | no |  | ≥ 1 items | انتخاب سبک که فقط برای تولید آهنگ از روی پرامپت بدون شعر در دسترس است؛ یک یا چند سبک موسیقی را انتخاب کنید. |
| `prompt` |  | string \| null | no |  | 1 – 2000 characters | توضیح آهنگ که نقش آن به ارسال lyrics بستگی دارد: در کنار lyrics سبک موسیقی را کنترل می‌کند و بدون lyrics الزامی است. آهنگ موردنظر، ازجمله حال‌وهوا، سازبندی و آوازها را توصیف کنید. |
| `gender` |  | enum (string) \| null | no |  | `female`, `male` | ترجیح جنسیت خواننده برای تولید آهنگ از روی شعر؛ فقط زمانی استفاده می‌شود که صدای بارگذاری‌شده یا شبیه‌سازی‌شده آن را جایگزین نکند. |
| `reference_id` |  | string \| null | no |  | ≥ 1 characters | شناسه موسیقی مرجع که از /files/upload با purpose='reference' دریافت شده است. |
| `vocal_id` |  | string \| null | no |  | ≥ 1 characters | شناسه صدا که از /voice/clone دریافت شده است. |
| `melody_id` |  | string \| null | no |  | ≥ 1 characters | شناسه ملودی برای استفاده بدون پرامپت، reference_id یا vocal_id. آن را از طریق /files/upload با purpose='melody' دریافت کنید. |
| `enable_safety_checker` |  | boolean | no | `true` |  | با تنظیم false، در صورت مجاز بودن فراخواننده، می‌توان بررسی را آسان‌گیرانه‌تر کرد. |

## Example input

Required parameters only:

```json
{}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/mureka/api/generate/song?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/mureka/api/generate/song?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/mureka/api/generate/song", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "mureka/api/generate/song",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
