# MiniMax H3 Reference to Video API

> 최대 9개의 이미지, 3개의 비디오와 3개의 오디오 참조로 5~15초 비디오를 생성하며 최대 4K를 지원합니다

Image 1, Video 1 또는 Audio 1처럼 순서로 참조를 인용하는 `prompt`에서 비디오를 생성합니다. 최대 9개의 이미지, 3개의 비디오 클립과 3개의 오디오 클립을 제공할 수 있으며 총 파일 수는 최대 12개입니다. `duration`은 5~15초, `resolution`은 480P, 768P, 2K 또는 4K이고 `aspect_ratio`에는 adaptive, 21:9, 16:9, 4:3, 1:1, 3:4 및 9:16이 포함됩니다.

- Model id: `minimax/h3/reference-to-video`
- Made by: MiniMax
- Category: Reference to Video
- Output: video
- Price per second of your output video: from $0.05 / second of output video (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/minimax/h3/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/minimax/h3/reference-to-video`
- Docs page: https://doitong.com/ko/developers/models/minimax/h3/reference-to-video

## Pricing

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

Price by tier:

- 480P: $0.05 / second of output video
- 768P: $0.06 / second of output video
- 2K: $0.13 / second of output video
- 4K: $0.16 / second of output video

The full example input below costs $0.65 = 650 API credits (5 s output video × $0.13 (2K)).

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/minimax/h3/reference-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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 50000 characters | 각 참조 목록에서 자산 유형과 위치로 식별되는 참조를 사용하는 동영상 생성 지침입니다. Audio 1, Video 1, Image 1, Image 2 등의 레이블을 사용합니다. |
| `duration` |  | integer | no | `5` | 5 – 15 | 동영상 길이이며, 초 단위로 측정됩니다. |
| `resolution` |  | enum (string) | no | `2K` | `480P`, `768P`, `2K`, `4K` | 생성된 동영상의 해상도를 선택합니다. 2K와 4K는 768P 기본 결과를 업스케일링하여 얻습니다. 480P 또는 768P를 선택하면 네이티브 생성을 사용합니다. |
| `seed` |  | integer \| null | no |  |  | 무작위 생성용 시드입니다. 생략하면 무작위로 선택됩니다. |
| `enable_safety_checker` |  | boolean | no | `true` |  | 안전 검사기 활성화입니다. true는 검사를 활성화합니다. |
| `prompt_expansion_mode` |  | string \| null | no | `balanced` |  | 생성 전 프롬프트 재작성 수준입니다. 최대 약 30초가 걸리는 더 풍부한 프롬프트에는 'quality'를, 약 1초 만에 결과를 얻으려면 'fast'를 선택하세요. 'balanced'에서는 요청마다 선택이 이루어지고, 'disabled'는 확장을 끕니다. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | 출력 동영상의 화면 비율입니다. |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 9 items | 피사체 또는 스타일 참조 이미지 URL입니다. 모든 동영상 및 오디오 참조와 공유하여 최대 12개 파일까지 사용할 수 있습니다. 프롬프트에서 목록 위치에 따라 Image 1, Image 2 등의 레이블로 이미지를 식별하세요. |
| `reference_video_urls` |  | array of video URL | no |  | ≤ 3 items | 프롬프트에서 목록 위치에 따라 Video 1, Video 2 등의 레이블로 식별하는 움직임 또는 기타 참조 동영상 URL입니다. 이미지, 동영상, 오디오 참조의 공유 한도는 12개 파일이며, 각 동영상 클립은 2–15초이고 총 길이는 15초 이하여야 합니다. |
| `reference_audio_urls` |  | array of audio URL | no |  | ≤ 3 items | 참조 오디오를 URL로 제공하고 프롬프트에서 Audio 1, Audio 2 등의 레이블로 클립을 식별하세요. 각 클립은 2–15초여야 하며 전체 오디오 길이는 15초 이하여야 합니다. 이미지, 동영상, 오디오 참조 유형은 하나만 제공하거나 조합할 수 있으며, 공유 최대 한도는 12개 파일입니다. |

File parameters (`images`, `reference_video_urls`, `reference_audio_urls`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/minimax/h3/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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/minimax/h3/reference-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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 = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3/reference-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.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": "minimax/h3/reference-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `video` | object {url, content_type, file_name, file_size} | 모델이 생성한 동영상입니다. |
| `expanded_prompt` | string \| null | 모델에 사용할 수 있도록 확장된 프롬프트이며, 확장된 텍스트가 없으면 null입니다. null이 되는 경우는 확장이 비활성화되었거나, 확장 결과가 변경되지 않았거나, 모델의 호스팅 API가 내부적으로 확장을 처리한 경우입니다. |
