# ElevenLabs Dubbing API

> Lồng tiếng tệp âm thanh hoặc video sang ngôn ngữ đích, với tùy chọn ngôn ngữ nguồn và số người nói

Dịch nội dung lời nói sang ngôn ngữ khác. Bắt buộc có `target_lang`, đồng thời cung cấp `audio_url` hoặc `video_url`; nếu cung cấp cả hai, video sẽ được sử dụng. `source_lang` được tự động phát hiện khi bỏ qua, và có thể đặt thủ công `num_speakers` (1 đến 50). Kết quả gồm âm thanh đã lồng tiếng, cùng video đã lồng tiếng nếu đầu vào có video.

- Model id: `elevenlabs/dubbing`

- Category: Lipsync & Avatars
- Output: video
- Price per minute of your input file: $0.60 / minute of input file (cheapest run $0.60 (600 API credits))
- Run: `POST https://api.doitong.com/v1/run/elevenlabs/dubbing`
- Quote: `POST https://api.doitong.com/v1/quote/elevenlabs/dubbing`
- Docs page: https://doitong.com/vi/developers/models/elevenlabs/dubbing

## Pricing

Price: **$0.60 / minute of input file**. Price per minute of your input file: 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.

The full example input below costs $0.60 = 600 API credits (1 min input file × $0.60).

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/elevenlabs/dubbing` 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

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `audio_url` | `audio` | string (audio URL) \| null | no |  |  | URL tệp âm thanh để lồng tiếng. Cung cấp ít nhất một trong `audio_url` và `video_url`. |
| `video_url` | `video` | string (video URL) \| null | no |  |  | URL video lồng tiếng, được ưu tiên hơn `audio_url` khi cả hai cùng được cung cấp. Yêu cầu phải chứa `video_url`, `audio_url` hoặc cả hai. |
| `target_lang` |  | string | yes |  |  | Ngôn ngữ đích của bản lồng tiếng, được chỉ định bằng mã ISO 639-1. |
| `source_lang` |  | string \| null | no |  |  | Mã nhận diện ngôn ngữ nguồn, được tự động phát hiện khi bỏ qua. |
| `num_speakers` |  | integer \| null | no |  | 1 – 50 | Để trống để mô hình tự phát hiện số người nói trong âm thanh, hoặc cung cấp rõ số người nói. |
| `highest_resolution` |  | boolean | no | `true` |  | Kiểm soát việc lồng tiếng có sử dụng độ phân giải cao nhất hiện có hay không. |

File parameters (`audio`, `video`) 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
{
  "target_lang": "es"
}
```

A fuller example:

```json
{
  "target_lang": "es"
}
```

## 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/elevenlabs/dubbing?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "target_lang": "es"
  }'

# 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/elevenlabs/dubbing?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "target_lang": "es"
  }),
});
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 = {
    "target_lang": "es",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/elevenlabs/dubbing", 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": "elevenlabs/dubbing",
      "input": {
        "target_lang": "es"
      },
      "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.
