# MiniMax H3 Text to Video API

> Model video MiniMax (Hailuo) untuk gerakan hidup, 5 hingga 15 detik, hingga 4K.

MiniMax H3 menghasilkan gerakan karakter dan kamera yang ekspresif dari prompt. Model merender secara native pada 480P atau 768P; opsi 2K dan 4K memperbesar hasil 768P. Klip berdurasi 5 hingga 15 detik dalam enam rasio aspek, penulis ulang prompt bawaan opsional memiliki empat tingkat upaya, dan Anda dapat menyematkan trek audio sendiri sebagai soundtrack.

## Pricing

Price: **from $0.05 / second (5 s ≈ $0.25)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 5).

The full example input below costs $0.36 = 360 API credits (6 s × 60 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/text-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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  | 1 – 50000 characters | Instruksi teks untuk membuat video. |
| `duration` |  | integer | no | `5` | 5 – 15 | Panjang video, diukur dalam detik. |
| `resolution` |  | enum (string) | no | `2K` | `480P`, `768P`, `2K`, `4K` | Pilih resolusi video yang dibuat, dengan 2K dan 4K diperoleh melalui upscaling basis 768P. Memilih 480P atau 768P menggunakan pembuatan native. |
| `seed` |  | integer \| null | no |  |  | Seed untuk pembuatan acak; jika tidak diberikan, seed dipilih secara acak. |
| `prompt_expansion_mode` |  | string \| null | no | `balanced` |  | Upaya penulisan ulang prompt sebelum pembuatan: pilih 'quality' untuk prompt yang lebih kaya dengan durasi hingga sekitar 30 detik, atau 'fast' untuk hasil dalam kira-kira satu detik. Dengan 'balanced', pilihan dibuat untuk setiap permintaan; 'disabled' menonaktifkan perluasan. |
| `target_audio_url` |  | string (audio URL) \| null | no |  | ≥ 1 characters | Soundtrack pengganti opsional yang disediakan melalui URL HTTP(S) atau URI data base64; klip harus berdurasi setidaknya 2 detik dan berukuran tidak lebih dari 15 MB. Audio yang disediakan menggantikan soundtrack yang dibuat dengan kecepatan pemutaran tetap: durasi berlebih dihapus dari akhir, sedangkan klip yang lebih pendek diberi jeda hening agar sesuai dengan video. Resampling ke 96 kHz dapat terjadi pada laju sampel yang sangat tinggi. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Rasio aspek video output. |

File parameters (`target_audio_url`) 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 white kitten chases a butterfly across a sunlit garden, gentle tracking camera, soft afternoon light"
}
```

A fuller example:

```json
{
  "prompt": "A white kitten chases a butterfly across a sunlit garden, gentle tracking camera, soft afternoon light",
  "duration": 6,
  "resolution": "768P"
}
```

## 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/text-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A white kitten chases a butterfly across a sunlit garden, gentle tracking camera, soft afternoon light",
    "duration": 6,
    "resolution": "768P"
  }'

# 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/text-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A white kitten chases a butterfly across a sunlit garden, gentle tracking camera, soft afternoon light",
    "duration": 6,
    "resolution": "768P"
  }),
});
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 white kitten chases a butterfly across a sunlit garden, gentle tracking camera, soft afternoon light",
    "duration": 6,
    "resolution": "768P",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3/text-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/text-to-video",
      "input": {
        "prompt": "A white kitten chases a butterfly across a sunlit garden, gentle tracking camera, soft afternoon light",
        "duration": 6,
        "resolution": "768P"
      },
      "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 |
