# H3 Max Camera Controls API

> Bheothaichidh e aon ìomhaigh air slighe chamara le prìomh-fhrèaman, le smachd air orbit, àrdachadh agus astar

Cleachdaidh e `image_url` mar a’ chiad fhrèam agus gluaisidh e an camara air `camera_trajectory`, liosta de 2 gu 12 prìomh-fhrèaman ann an òrdugh. Gu bunaiteach, fuirichidh an sealladh cruaidh gus nach atharraich ach an camara. Tha an ùine 0.92 gu 15 diog, le rùn 480P, 768P no 1080P. Faodar leudachadh a’ phrompt atharrachadh.

- 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 $0.25 = 250 API credits (5 s × 50 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 gineadh bhidio a’ dol thairis air giùlan bun-roghainn an t-seallaidh reòta. Ma dh’fhàgas tu bàn e no ma dh’fhàgas tu às e, cumaidh e an sealladh iomraidh stèidhichte agus leigidh e gluasad camara a-mhàin. |
| `duration` |  | number | no | `5` | 0.92 – 15 | Ùine iarrte ann an diogan, a’ ceadachadh fad bhidio fhèin suas ri mu 0.7 s nas fhaide na an t-iarrtas sin. |
| `resolution` |  | enum (string) | no | `480P` | `480P`, `768P`, `1080P` | Roghainn dùmhlachd-bhreacaidh gineadh: feumaidh 1080P ùrachadh latent de stuth a chaidh a ghineadh gu dùthchasach aig 768P, seach gineadh dùthchasach aig an dùmhlachd-bhreacaidh a chaidh a thaghadh. |
| `seed` |  | integer \| null | no |  |  | Sìol airson gineadh air thuaiream; mura tèid a shònrachadh, thèid fear a thaghadh air thuaiream. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Gnìomhachadh an t-sgrùdaiche sàbhailteachd; tha true a’ comasachadh sgrùdaidh. |
| `prompt_expansion_mode` |  | string | yes | `balanced` |  | Oidhirp ath-sgrìobhaidh a’ prompt ro ghineadh: bidh 'quality' a’ leasachadh prompt nas beartaiche ann an suas ri mu 30s, agus tillidh 'balanced' ann an timcheall air diog. Tagh 'disabled' gus leudachadh a sheachnadh. |
| `image_url` | `image` | string (image URL) | yes |  | ≥ 1 characters | URL ìomhaigh a’ mìneachadh a’ chiad fhrèam den bhidio. |
| `camera_trajectory` |  | array of object {time, azimuth, elevation, distance} | no |  | 2 – 12 items | Keyframes camara òrdaichte le cuairteachadh slàn soidhnichte air a chumail agus siubhal azimuth iomlan air a chuingealachadh gu 32 tionndadh. Taobh a-muigh raon-ùine nan keyframes, cumaidh an camara a’ chiad shuidheachadh ron stampa-ùine aige agus an suidheachadh mu dheireadh gu deireadh a’ bhidio. |
| `camera_trajectory[].time` |  | number | yes |  | 0 – 1 | Ùine àbhaisteach taobh a-staigh a’ bhidio, a’ cleachdadh an eadar-ama [0, 1] gus a thoiseach agus a cheann a riochdachadh, fa leth. |
| `camera_trajectory[].azimuth` |  | number | yes |  |  | Ceàrn chòmhnard a’ chamara mun cuairt air a’ chuspair, air a thomhas ann an ceuman. |
| `camera_trajectory[].elevation` |  | number | yes |  | -90 – 90 | Ceàrn dhìreach a’ chamara mun cuairt air a’ chuspair, air a thomhas ann an ceuman. |
| `camera_trajectory[].distance` |  | number | yes |  | > 0 | Astar eadar an camara agus an cuspair, air a thomhas ann an aonadan seallaidh àbhaisteach. |

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

## 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

### 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} | Bhidio a chaidh a chruthachadh leis a’ mhodail. |
| `expanded_prompt` | string \| null | Prompt leudaichte deiseil airson a’ mhodail, no null mura bheil teacsa leudaichte ri fhaighinn. Is iad na cùisean null leudachadh ciorramach, leudachadh nach do rinn atharrachadh, agus leudachadh air a làimhseachadh a-staigh le API aoigheachd a’ mhodail. |
| `timings` | object \| null | Tomhasan tìmeachaidh air an cur an cèill ann an diogan, rim faighinn a-mhàin air puingean-crìche a bhios ag aithris tìmeachadh backend; air neo null. Bidh an inntrigeadh 'inference' a’ tomhas dè cho fada ’s a thug dì-noising DiT air backend GPU. |
