# H3 Max Hand Drawn API

> Text-to-video theo phong cách hoạt ảnh vẽ tay, kiểu bút chì, với ảnh khung hình đầu tùy chọn

Tạo các đoạn hoạt ảnh có âm thanh theo phong cách vẽ tay được áp dụng tự động, để lời nhắc có thể tập trung vào cảnh, hành động, máy quay và âm thanh. `image_url` khung hình đầu tiên là tùy chọn, và hình vẽ bằng bút chì phù hợp nhất với diện mạo này; tỷ lệ khung hình của nó đặt canvas. Không có hình ảnh, hãy chọn `aspect_ratio` từ 21:9 đến 9:16. `duration` từ 5 đến 15 giây và đầu ra là 768P.

- Made by: MiniMax
- Category: Text to Video
- Output: video
- Price: $0.08 / second (5 s ≈ $0.40) (cheapest run $0.40 (400 API credits))
- Run: `POST https://api.doitong.ru/v1/run/minimax/h3-max/styles/hand-drawn`
- Quote: `POST https://api.doitong.ru/v1/quote/minimax/h3-max/styles/hand-drawn`

## Pricing

Price: **$0.08 / second (5 s ≈ $0.40)**. Billed per second of output (`duration`, default 15).

The full example input below costs $0.40 = 400 API credits (5 s × 80 API credits).

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/styles/hand-drawn` 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 – 49868 characters | Lời nhắc cho video tự động áp dụng phong cách vẽ tay; chỉ định bối cảnh, hành động, hành vi camera và âm thanh. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | Hình ảnh tùy chọn có tỷ lệ xác định tỷ lệ khung hình canvas và nội dung cung cấp khung hình mở đầu. Khuyến nghị dùng tranh chì để đạt tính nhất quán hình ảnh tối đa. |
| `duration` |  | integer | no | `5` | 5 – 15 | Độ dài mong muốn của video, đo bằng giây. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Tỷ lệ khung hình dùng khi tạo chỉ từ văn bản. Không có tác dụng nếu cung cấp image_url. |
| `seed` |  | integer \| null | no |  |  | Seed ngẫu nhiên; không chỉ định sẽ tự động chọn seed. |

File parameters (`image`) 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.ru/v1/run/minimax/h3-max/styles/hand-drawn?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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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-max/styles/hand-drawn?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.ru/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-max/styles/hand-drawn", 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/styles/hand-drawn",
      "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.
