# Sync Lipsync 3 API

> Athamaíonn sé liopaí aon fhíseáin chainte le rian fuaime nua.

Cuireann sync-lipsync-3 de chuid Sync Labs gluaiseacht bhéil duine i bhfíseán in áit chun í a mheaitseáil le rian gutha nua, le haghaidh dubála, logánú fógraí agus línte a dheisiú san iar-léiriú. Nuair a bhíonn faid na fuaime agus an fhíseáin éagsúil, roghnaigh gearradh, athdhéanamh, preabadh, ciúnas a chur leis nó athmhapáil.

- 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/ga/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

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",
  "audio": "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/sync-lipsync/v3?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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"
  }'

# 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

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/sync-lipsync/v3?wait=20", {

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

# Run the model; wait up to 20 s for the finished result in the same call
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.
