# Mureka 9.5 Instrumental Generation API

> ٹیکسٹ پرامپٹ یا اپ لوڈ کیے گئے سازینہ ریفرنس ID سے آواز کے بغیر سازینہ ٹریکس بناتا ہے

`prompt` (زیادہ سے زیادہ 1024 حروف) یا پہلے اپ لوڈ کیے گئے `instrumental_id` سے سازینہ موسیقی تیار کرتا ہے؛ عین ایک فراہم کریں۔ `model` فیلڈ ورژن منتخب کرتا ہے: mureka-7.6، mureka-8، mureka-9 یا mureka-9.5 (ڈیفالٹ)۔ نتیجے میں آڈیو فائل، دستیاب ہونے پر ملی سیکنڈز میں اس کا دورانیہ، دستیاب ہونے پر وقت کے ساتھ بولوں کے حصے، اور lyrics ویڈیو جیسے دیگر اینڈ پوائنٹس کے لیے دوبارہ استعمال کے قابل `song_id` شامل ہوتا ہے۔

- Model id: `mureka/api/generate/instrumental`
- Made by: Mureka
- Category: Text to Music
- Output: audio
- Price: from $0.045 / request (cheapest run $0.045 (45 API credits))
- Run: `POST https://api.doitong.com/v1/run/mureka/api/generate/instrumental`
- Quote: `POST https://api.doitong.com/v1/quote/mureka/api/generate/instrumental`
- Docs page: https://doitong.com/ur/developers/models/mureka/api/generate/instrumental

## Pricing

Price: **from $0.045 / request** (the lowest tier; the quote prices your exact input). Billed once per request.

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `model` = mureka-9.5: $0.225 (225 API credits) / request
- When `model` = mureka-9: $0.0675 (67.5 API credits) / request
- When `model` = mureka-8: $0.0675 (67.5 API credits) / request

The full example input below costs $0.225 = 225 API credits (1 request × 225 API credits).

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/instrumental` 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-8`, `mureka-9`, `mureka-9.5` | instrumental تخلیق کے لیے منتخب ماڈل۔ |
| `prompt` |  | string \| null | no |  | 1 – 1024 characters | instrumental_id کے متبادل پرامپٹ کے طور پر فراہم کردہ instrumental description؛ ان دونوں میں سے عین ایک فراہم کرنا لازم ہے۔ |
| `instrumental_id` |  | string \| null | no |  | ≥ 1 characters | پرامپٹ کے بجائے instrumental_id کے طور پر فراہم کیا گیا Instrumental ID؛ عین ایک درکار ہے۔ ID /files/upload کے ذریعے purpose='instrumental' کے ساتھ حاصل کریں۔ |
| `enable_safety_checker` |  | boolean | no | `true` |  | false سیٹ کر کے اسکریننگ نرم کی جا سکتی ہے، بشرطیکہ کال کرنے والا مجاز ہو۔ |

## 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/instrumental?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/instrumental?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/instrumental", 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/instrumental",
      "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.
