# Kling Video Create Voice API

> 5-30 s کے آڈیو یا ویڈیو نمونے سے حسبِ ضرورت آواز رجسٹر کرتا ہے اور voice ID واپس کرتا ہے

Kling ماڈلز کے وائس کنٹرول کے لیے دوبارہ استعمال کے قابل آواز بناتا ہے۔ `voice_url` میں .mp3/.wav آڈیو یا .mp4/.mov ویڈیو کا لنک دیں، جس کی لمبائی 5-30 سیکنڈ ہو اور اس میں صاف، ایک آواز میں تقریر ہو۔ نتیجہ ایک `voice_id` اسٹرنگ ہوتا ہے جو نئی آواز کی شناخت کرتا ہے۔

- Model id: `kling-video/create-voice`
- Made by: Kling
- Category: Audio
- Output: json
- Price: $0.007 / request (cheapest run $0.007 (7 API credits))
- Run: `POST https://api.doitong.com/v1/run/kling-video/create-voice`
- Quote: `POST https://api.doitong.com/v1/quote/kling-video/create-voice`
- Docs page: https://doitong.com/ur/developers/models/kling-video/create-voice

## Pricing

Price: **$0.007 / request**. Billed once per request.

The full example input below costs $0.007 = 7 API credits (1 request × 7 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/kling-video/create-voice` 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 |
|---|---|---|---|---|---|---|
| `enable_safety_checker` |  | boolean | no | `true` |  | حفاظتی جانچ صرف اکاؤنٹ کی اجازت کے ساتھ غیر فعال کی جا سکتی ہے؛ بغیر اجازت کی درخواستوں کی ہمیشہ جانچ ہوتی ہے۔ |
| `voice_url` |  | string (audio URL) | yes |  |  | آواز کی ریکارڈنگ کی طرف اشارہ کرنے والا URL، .mp3 یا .wav آڈیو، یا .mp4 یا .mov ویڈیو فارمیٹ میں۔ ریکارڈنگ 5–30 سیکنڈ کی ہو اور اس میں ایک ہی آواز کے ساتھ صاف آڈیو شامل ہو۔ |

File parameters (`voice_url`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "voice_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "voice_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## 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/kling-video/create-voice?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "voice_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# 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/kling-video/create-voice?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "voice_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }),
});
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 = {
    "voice_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/kling-video/create-voice", 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": "kling-video/create-voice",
      "input": {
        "voice_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "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.
