# H3 Max Camera Controls API

> Menganimasikan satu gambar mengikuti jalur kamera berbasis keyframe dengan kontrol orbit, elevasi, dan jarak

Menggunakan `image_url` sebagai bingkai pertama dan menggerakkan kamera sepanjang `camera_trajectory`, yaitu daftar 2 hingga 12 bingkai kunci berurutan. Secara bawaan, adegan tetap kaku sehingga hanya kamera yang berubah. Durasi adalah 0.92 hingga 15 detik, dengan resolusi 480P, 768P, atau 1080P. Perluasan prompt dapat disesuaikan.

- Model id: `minimax/h3-max/camera-controls`
- Made by: MiniMax
- Category: Image to Video
- Output: video
- Price: from $0.0325 / second (5 s ≈ $0.163) (cheapest run $0.163 (163 API credits))
- Run: `POST https://api.doitong.com/v1/run/minimax/h3-max/camera-controls`
- Quote: `POST https://api.doitong.com/v1/quote/minimax/h3-max/camera-controls`
- Docs page: https://doitong.com/id/developers/models/minimax/h3-max/camera-controls

## Pricing

Price: **from $0.0325 / second (5 s ≈ $0.163)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 768P: $0.052 (52 API credits) / second
- When `resolution` = 1080P: $0.104 (104 API credits) / second

The full example input below costs $0.163 = 163 API credits (5 s × 32.5 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.com/v1/quote/minimax/h3-max/camera-controls` 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 | no | `The same elements in the reference are rigid. Preserve every element exactly. The entire scene is frozen. Only the camera moves. no scene motion only camera motion` | ≤ 50000 characters | Prompt pembuatan video yang menimpa perilaku adegan-beku bawaan. Membiarkannya kosong atau tidak menyertakannya akan mempertahankan adegan referensi tetap dan hanya mengizinkan pergerakan kamera. |
| `duration` |  | number | no | `5` | 0.92 – 15 | Durasi yang diminta dalam detik, dengan panjang video aktual hingga sekitar 0.7 detik lebih lama dari permintaan tersebut. |
| `resolution` |  | enum (string) | no | `480P` | `480P`, `768P`, `1080P` | Pilihan resolusi pembuatan: 1080P memerlukan penyempurnaan laten dari materi yang dibuat secara native pada 768P, bukan pembuatan native pada resolusi yang dipilih. |
| `seed` |  | integer \| null | no |  |  | Seed untuk pembuatan acak; jika tidak diberikan, seed dipilih secara acak. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Aktivasi pemeriksa keamanan; true mengaktifkan pemeriksaan. |
| `prompt_expansion_mode` |  | string | yes | `balanced` |  | Upaya penulisan ulang prompt sebelum pembuatan: 'quality' mengembangkan prompt yang lebih kaya selama sekitar 30 detik, sedangkan 'balanced' mengembalikan hasil dalam kira-kira satu detik. Pilih 'disabled' untuk menghilangkan perluasan prompt. |
| `image_url` | `image` | string (image URL) | yes |  | ≥ 1 characters | URL gambar yang menentukan bingkai pembuka video. |
| `camera_trajectory` |  | array of object {time, azimuth, elevation, distance} | no |  | 2 – 12 items | Keyframe kamera berurutan dengan rotasi penuh bertanda tetap dipertahankan dan total perpindahan azimut dibatasi hingga 32 putaran. Di luar rentang waktu keyframe, kamera mempertahankan pose pertama sebelum timestamp-nya dan pose terakhir hingga akhir video. |
| `camera_trajectory[].time` |  | number | yes |  | 0 – 1 | Waktu yang dinormalisasi dalam video, menggunakan interval [0, 1] untuk masing-masing merepresentasikan awal dan akhir video. |
| `camera_trajectory[].azimuth` |  | number | yes |  |  | Sudut horizontal kamera terhadap subjek, diukur dalam derajat. |
| `camera_trajectory[].elevation` |  | number | yes |  | -90 – 90 | Sudut vertikal kamera terhadap subjek, diukur dalam derajat. |
| `camera_trajectory[].distance` |  | number | yes |  | > 0 | Jarak antara kamera dan subjek, diukur dalam unit adegan yang dinormalisasi. |

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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "prompt_expansion_mode": "balanced"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "prompt_expansion_mode": "balanced"
}
```

## 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-max/camera-controls?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "prompt_expansion_mode": "balanced"
  }'

# 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

  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 = {
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3-max/camera-controls", 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-max/camera-controls",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "prompt_expansion_mode": "balanced"
      },
      "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} | Video yang dihasilkan oleh model. |
| `expanded_prompt` | string \| null | Prompt yang diperluas dan siap digunakan model, atau null jika teks yang diperluas tidak tersedia. Kasus null mencakup perluasan yang dinonaktifkan, perluasan yang tidak mengubah apa pun, dan perluasan yang ditangani secara internal oleh API yang di-host model. |
| `timings` | object \| null | Pengukuran waktu yang dinyatakan dalam detik, hanya tersedia pada rute yang melaporkan waktu backend; jika tidak, null. Entri 'inference' mengukur durasi denoising DiT pada backend GPU. |
