# H3 Max Camera Controls API

> Yörünge, yükselme ve mesafe denetimiyle tek bir görüntüyü ana kareli kamera yolu boyunca canlandırır

`image_url` değerini ilk kare olarak kullanır ve kamerayı 2 ile 12 arasında sıralı ana kareden oluşan `camera_trajectory` boyunca hareket ettirir. Varsayılan olarak sahne sabit kalır ve yalnızca kamera değişir. Süre 0.92 ile 15 saniye arasındadır; çözünürlük 480P, 768P veya 1080P'dir. İstem genişletme ayarlanabilir.

- Model id: `minimax/h3-max/camera-controls`

- 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`

## 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 | Varsayılan donmuş sahne davranışını geçersiz kılan video üretim istemi. Boş bırakmak veya belirtmemek referans sahnesini sabit tutar ve yalnızca kamera hareketine izin verir. |
| `duration` |  | number | no | `5` | 0.92 – 15 | Saniye cinsinden istenen süre; gerçek video uzunluğunun bu isteğin yaklaşık 0.7 saniye üzerine çıkmasına izin verir. |
| `resolution` |  | enum (string) | no | `480P` | `480P`, `768P`, `1080P` | Üretim çözünürlüğü seçimi: 1080P, seçilen çözünürlükte yerel üretim yerine 768P'de yerel olarak üretilen materyalin gizil iyileştirilmesini gerektirir. |
| `seed` |  | integer \| null | no |  |  | Rastgele üretim için tohum; belirtilmezse rastgele bir tane seçilir. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Güvenlik denetleyicisi etkinleştirme; true denetimi etkinleştirir. |
| `prompt_expansion_mode` |  | string | yes | `balanced` |  | Üretim öncesi istem yeniden yazma çabası: 'quality', yaklaşık 30 saniyeye kadar daha zengin bir istem geliştirirken 'balanced' yaklaşık bir saniyede sonuç döndürür. İstem genişletmeyi atlamak için 'disabled' seçin. |
| `image_url` | `image` | string (image URL) | yes |  | ≥ 1 characters | Videonun açılış karesini tanımlayan görsel URL'si. |
| `camera_trajectory` |  | array of object {time, azimuth, elevation, distance} | no |  | 2 – 12 items | İmzalı tam dönüşleri korunan ve toplam azimut hareketi 32 dönüşle sınırlanan sıralı kamera anahtar kareleri. Ana karelerin zaman aralığının dışında kamera, zaman damgasından önce ilk pozu ve videonun sonuna kadar son pozu korur. |
| `camera_trajectory[].time` |  | number | yes |  | 0 – 1 | Video içindeki normalize edilmiş zaman; [0, 1] aralığı sırasıyla başlangıç ve sonu temsil eder. |
| `camera_trajectory[].azimuth` |  | number | yes |  |  | Kameranın konu etrafındaki yatay açısı, derece cinsinden ölçülür. |
| `camera_trajectory[].elevation` |  | number | yes |  | -90 – 90 | Kameranın konu etrafındaki dikey açısı, derece cinsinden ölçülür. |
| `camera_trajectory[].distance` |  | number | yes |  | > 0 | Kamera ile konu arasındaki mesafe, normalize edilmiş sahne birimleriyle ölçülür. |

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

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

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

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} | Model tarafından üretilen video. |
| `expanded_prompt` | string \| null | Model için hazır genişletilmiş istem veya genişletilmiş metin yoksa null. null durumları genişletmenin devre dışı olması, genişletmenin değişiklik yapmaması ve genişletmenin modelin barındırılan API'si tarafından dahili olarak işlenmesidir. |
| `timings` | object \| null | Saniye cinsinden ifade edilen zamanlama ölçümleri; yalnızca arka uç zamanlamalarını raporlayan rotalarda kullanılabilir, aksi halde null. 'inference' girdisi, DiT gürültü giderme işleminin GPU arka ucunda ne kadar sürdüğünü ölçer. |
