# H3 Max Camera Controls API

> Ka hākoritanga i tētahi atahanga mā te ara kāmera anga matua, me te whakahaere i te hurihanga, te teitei me te tawhiti

Ka whakamahi `image_url` hei anga tuatahi, ka neke i te kāmera mā `camera_trajectory`, he rārangi 2 ki te 12 ngā anga matua kua whakaraupapatia. Mā te taunoa, ka pūmau te whakaaturanga, nō reira ko te kāmera anake ka panoni. Ko te roa 0.92 ki te 15 hēkona, me te taumira 480P, 768P, 1080P rānei. Ka taea te whakatika i te whakawhānui tohutohu.

- 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`

## 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 | He tohutohu whakaputa-ataata ka whakakapi i te whanonga taunoa o te whakaari whakatio. Ki te waiho kia wātea, ki te kore rānei e tukuna, ka mau tonu te whakaari tohutoro, ā, ko te nekehanga kāmera anake ka whakaaetia. |
| `duration` |  | number | no | `5` | 0.92 – 15 | Te roanga tono i ngā hēkona, ka taea ai he roanga ataata tūturu kia 0.7 s pea te nui atu i taua tono. |
| `resolution` |  | enum (string) | no | `480P` | `480P`, `768P`, `1080P` | Kōwhiringa taumira whakaputanga: me whakamahine ā-ngohe te 1080P i ngā rawa i whakaputaina taketake ki te 768P, kaua ko te whakaputanga taketake ki te taumira kua kōwhiria. |
| `seed` |  | integer \| null | no |  |  | Kākano mō te whakaputanga matapōkere; ki te waiho, ka kōwhiria matapōkeretia. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Whakahohe kaitaki haumaru; mā true e whakahohe te tirotiro. |
| `prompt_expansion_mode` |  | string | yes | `balanced` |  | Ngā kaha ki te tuhi anō i te tohutohu i mua i te whakaputanga: ka whakawhanake a 'quality' i tētahi tohutohu whai kiko ake mō te 30s pea, engari ka whakahoki a 'balanced' i roto i te hēkona kotahi pea. Kōwhiria 'disabled' kia kore ai e whakawhānuitia te tohutohu. |
| `image_url` | `image` | string (image URL) | yes |  | ≥ 1 characters | He URL atahanga e tautuhi ana i te anga tīmatanga o te ataata. |
| `camera_trajectory` |  | array of object {time, azimuth, elevation, distance} | no |  | 2 – 12 items | Ngā keyframe kāmera kua raupapatia, me ngā hurihanga katoa whai-tohu kua puritia, ā, kua herea te haerenga azimuth katoa ki te 32 hurihanga. Kei waho atu i te awhe wā o ngā keyframe, ka pupuri te kāmera i te tūnga tuatahi i mua i tōna tohu wā, ā, i te tūnga whakamutunga tae noa ki te mutunga o te ataata. |
| `camera_trajectory[].time` |  | number | yes |  | 0 – 1 | Wā kua whakatauritea i roto i te ataata, mā te wāhanga [0, 1] e tohu ai i tōna tīmatanga me tōna mutunga. |
| `camera_trajectory[].azimuth` |  | number | yes |  |  | Te koki whakapae o te kāmera huri noa i te kaupapa, ka inea ki ngā nekehanga. |
| `camera_trajectory[].elevation` |  | number | yes |  | -90 – 90 | Te koki poutū o te kāmera huri noa i te kaupapa, ka inea ki ngā nekehanga. |
| `camera_trajectory[].distance` |  | number | yes |  | > 0 | Te tawhiti i waenganui i te kāmera me te kaupapa, ka inea ki ngā waeine whakaari kua whakatauritea. |

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

```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

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",

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} | Te ataata i hangaia e te tauira. |
| `expanded_prompt` | string \| null | He tohutohu kua whakawhānuitia, kua rite mō te tauira, he null rānei mēnā kāore he kuputuhi whakawhānui. Ko ngā take null ko te whakawhānui kua mono, te whakawhānui kāore i panoni, me te whakawhānui i whakahaere ā-roto e te API manaaki a te tauira. |
| `timings` | object \| null | Ngā inenga wā i whakaaturia ki ngā hēkona, ka wātea anake ki ngā ara e tuku ana i ngā wā backend; ki te kore, he null. Mā te urunga 'inference' e ine te roa o te denoising DiT i runga i te backend GPU. |
