# H3 Max Lip Sync Image to Video API

> تبدیل تصویر پرتره و فایل صوتی به ویدئوی گفتاری هماهنگ با لب، تا 2K

یک تصویر را متحرک می‌کند تا حرکت دهان با فایل صوتی ارائه‌شده هماهنگ شود. صدا باید حداقل 5 ثانیه باشد، تا 15 دقیقه را پشتیبانی می‌کند و طول خروجی با آن برابر است. نسبت تصویر باید بین 0.4 و 2.5 باشد. `resolution` از 480P تا 2K است و `enable_transcription` می‌تواند رونوشت را برای هدایت همگام‌سازی اضافه کند.

- Model id: `minimax/h3-max/lip-sync/image-to-video`
- Made by: MiniMax
- Category: Lipsync & Avatars
- Output: video
- Price per second of your input audio: from $0.05 / second of input audio (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.ru/v1/run/minimax/h3-max/lip-sync/image-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/minimax/h3-max/lip-sync/image-to-video`
- Docs page: https://doitong.com/fa/developers/models/minimax/h3-max/lip-sync/image-to-video

## Pricing

Price: **from $0.05 / second of input audio** (the lowest tier; the quote prices your exact input). Price per second of your input audio: 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.

Price by tier:

- 480P: $0.05 / second of input audio
- 480P, over 15 s: $0.06 / second of input audio
- 768P: $0.08 / second of input audio
- 768P, over 15 s: $0.096 / second of input audio
- 1080P: $0.16 / second of input audio
- 1080P, over 15 s: $0.192 / second of input audio
- 2K: $0.32 / second of input audio
- 2K, over 15 s: $0.384 / second of input audio

The full example input below costs $0.80 = 800 API credits (10 s input audio × $0.08 (768P)).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.ru/v1/quote/minimax/h3-max/lip-sync/image-to-video` 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 |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | تصویر ورودی انیمیشن؛ فقط نسبت‌های ابعاد در بازهٔ 0.4–2.5 پذیرفته می‌شوند. |
| `audio_url` | `audio` | string (audio URL) | yes |  |  | صوت هدایت‌کنندهٔ حرکات دهان، با مدت پشتیبانی‌شدهٔ 5 ثانیه تا 15 دقیقه. ویدیوی تولیدشده همان مدت صوت را دارد. |
| `resolution` |  | enum (string) | no | `768P` | `480P`, `768P`, `1080P`, `2K` | وضوح خروجی تولیدشده، با استفاده از نزدیک‌ترین نسبت ابعاد پشتیبانی‌شده به نسبت تصویر. |
| `enable_transcription` |  | boolean | no | `false` |  | کمک به رونویسی برای همگام‌سازی لب‌ها. در حالت غیرفعال، همگام‌سازی فقط از صوت استفاده می‌کند؛ با فعال‌سازی، صوت ارائه‌شده رونویسی شده و آن رونویس به‌عنوان راهنما استفاده می‌شود. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 | Seed برای تولید تصادفی؛ حذف آن باعث انتخاب تصادفی می‌شود. |
| `enable_safety_checker` |  | boolean | no | `true` |  | مشخص می‌کند غربالگری ایمنی محتوا فعال باشد یا نه. |

File parameters (`image`, `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
{
  "image": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
  "audio_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.ru/v1/run/minimax/h3-max/lip-sync/image-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
    "audio_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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

  "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/minimax/h3-max/lip-sync/image-to-video?wait=20", {

  }),
});
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.ru/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
    "audio_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/minimax/h3-max/lip-sync/image-to-video", 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.ru/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": "minimax/h3-max/lip-sync/image-to-video",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/avatar/talking_avatar.jpg",
        "audio_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.
