# Sync Lipsync 3 API

> کسی بھی گفتگو کرتی ویڈیو کے ہونٹوں کا وقت نئے آڈیو ٹریک کے مطابق تبدیل کرتا ہے۔

Sync Labs کا lipsync-3 ویڈیو میں موجود شخص کی منہ کی حرکت کو تبدیل کرتا ہے تاکہ وہ نئی آواز کے ٹریک سے مطابقت رکھے، ڈبنگ، اشتہارات کی لوکلائزیشن اور پوسٹ میں لائنیں درست کرنے کے لیے۔ آڈیو اور ویڈیو کی لمبائیاں مختلف ہوں تو کٹ، لوپ، باؤنس، خاموشی سے پیڈ یا ری میپ کرنے کا انتخاب کریں۔

- Model id: `sync-lipsync/v3`
- Made by: Sync Labs
- Category: Lipsync & Avatars
- Output: video
- Price per minute of your output video: $8.00 / minute of output video (cheapest run $8.00 (8000 API credits))
- Run: `POST https://api.doitong.com/v1/run/sync-lipsync/v3`
- Quote: `POST https://api.doitong.com/v1/quote/sync-lipsync/v3`
- Docs page: https://doitong.com/ur/developers/models/sync-lipsync/v3

## Pricing

Price: **$8.00 / minute of output video**. Price per minute of your output video: 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 $1.334 = 1334 API credits (0.1667 min output video × $8.00).

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/sync-lipsync/v3` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | ان پٹ ویڈیو کی طرف اشارہ کرنے والا URL۔ |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | URL کے طور پر ان پٹ آڈیو کا مقام۔ |
| `sync_mode` |  | enum (string) | no | `cut_off` | `cut_off`, `loop`, `bounce`, `silence`, `remap` | آڈیو اور ویڈیو کی مدت کے فرق سے نمٹنے کے لیے lip synchronization mode۔ |
| `options` |  | object {sync_mode, model_mode, prompt, temperature, active_speaker_detection, occlusion_detection_enabled} \| null | no |  |  | اضافی Sync.so تخلیق behavior یہاں configure کریں؛ فراہم کردہ options.sync_mode کو top-level sync_mode value پر ترجیح حاصل ہے۔ |
| `options.sync_mode` |  | enum (string) \| null | no |  | `cut_off`, `loop`, `bounce`, `silence`, `remap` | top-level sync_mode کا override، جو بتاتا ہے کہ ان پٹ آڈیو اور ویڈیو کی مدت مختلف ہونے پر کیا ہو۔ |
| `options.model_mode` |  | enum (string) \| null | no |  | `lips`, `face`, `head`, `lipsync`, `emotion`, `talking_head` | editing-area selection، بنیادی طور پر react-1 کے لیے، جو بتاتی ہے کہ ماڈل کون سا region تبدیل کرے۔ |
| `options.prompt` |  | enum (string) \| null | no |  | `happy`, `sad`, `angry`, `disgusted`, `surprised`, `neutral` | emotion guidance، بنیادی طور پر react-1 کے ذریعے تخلیق کی سمت متعین کرنے کے لیے استعمال ہوتی ہے۔ |
| `options.temperature` |  | number \| null | no |  | 0 – 1 | expressiveness setting، sync-3 پر بے اثر کیونکہ وہ اسے native طور پر manage کرتا ہے۔ اس setting والے ماڈلز میں 0 کم ترین اور 1 زیادہ ترین expressive lipsync دیتا ہے۔ |
| `options.active_speaker_detection` |  | object {auto_detect, v3, use_v2, frame_number, coordinates, bounding_boxes, bounding_boxes_url, face_image} \| null | no |  |  | متعدد افراد والی ویڈیوز میں active speaker کی شناخت کی settings۔ |
| `options.active_speaker_detection.auto_detect` |  | boolean \| null | no |  |  | active speaker کی خودکار شناخت اور اس شخص پر تخلیق کا اطلاق۔ |
| `options.active_speaker_detection.v3` |  | boolean \| null | no |  |  | v3 active-speaker detection کا استعمال۔ |
| `options.active_speaker_detection.use_v2` |  | boolean \| null | no |  |  | v2 active-speaker detection کے لیے deprecated setting۔ |
| `options.active_speaker_detection.frame_number` |  | integer \| null | no |  | ≥ 0 | speaker کو دستی طور پر منتخب کرنے والے coordinates کے لیے استعمال ہونے والے فریم کا index۔ |
| `options.active_speaker_detection.coordinates` |  | array of integer \| null | no |  | 2 – 2 items | frame_number میں speaker کے لیے [x, y] کے طور پر دیا گیا facial reference point۔ |
| `options.active_speaker_detection.bounding_boxes` |  | array of array of integer \| null | no |  |  | ہر فریم کے لیے detected face bounding boxes، [x1, y1, x2, y2] کے طور پر بیان کیے گئے۔ |
| `options.active_speaker_detection.bounding_boxes_url` |  | string \| null | no |  |  | ہر فریم کے bounding boxes فراہم کرنے والے JSON فائل URL۔ |
| `options.active_speaker_detection.face_image` |  | string \| null | no |  |  | Base64 میں encoded چہرے کی تصویر، speaker کو دستی طور پر منتخب کرنے کے لیے استعمال ہوتی ہے۔ |
| `options.occlusion_detection_enabled` |  | boolean \| null | no |  |  | occlusion-detection toggle؛ sync-3 پر بے اثر کیونکہ وہاں detection خودکار ہے، بصورت دیگر یہ متعین کرتا ہے کہ تخلیق میں occlusion detection شامل ہو یا نہیں۔ |

File parameters (`video`, `audio`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",

## 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/sync-lipsync/v3?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \

    "audio": "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

### Python

```python
import os
import requests

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

payload = {
    "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",

r = requests.post(API + "/run/sync-lipsync/v3", 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": "sync-lipsync/v3",
      "input": {
        "video": "https://content.doitong.com/video/showcase/v3/avatar/talking_avatar_loop.mp4",
        "audio": "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.
