# H3 Max Low Poly API

> No teksta ģenerēts video retro zema poligonu skaita 3D stilā ar neobligātu pirmā kadra attēlu

Izveido īsus klipus ar audio, kas izskatās kā retro zema poligonu skaita 3D animācija, automātiski pievienojot šo stilu. Aprakstiet ainu, darbību, kameru un skaņu laukā `prompt`. Neobligāts `image_url` kalpo kā pirmais kadrs; vēlams izmantot zema poligonu skaita vai retro 3D mākslu, un tas ignorē `aspect_ratio`. Ilgums ir no 5 līdz 15 sekundēm, bet rezultāts ir 768P.

- Model id: `minimax/h3-max/styles/low-poly`
- Made by: MiniMax
- Category: Text to Video
- Output: video
- Price: $0.08 / second (5 s ≈ $0.40) (cheapest run $0.40 (400 API credits))
- Run: `POST https://api.doitong.com/v1/run/minimax/h3-max/styles/low-poly`
- Quote: `POST https://api.doitong.com/v1/quote/minimax/h3-max/styles/low-poly`
- Docs page: https://doitong.com/lv/developers/models/minimax/h3-max/styles/low-poly

## Pricing

Price: **$0.08 / second (5 s ≈ $0.40)**. Billed per second of output (`duration`, default 15).

The full example input below costs $0.40 = 400 API credits (5 s × 80 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/styles/low-poly` 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 | yes |  | 1 – 49914 characters | Uzvedne video, kas automātiski renderēts retro zemas poligonalitātes 3D stilā; norādiet vidi, darbību, kameras uzvedību un audio. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | Neobligāts sākuma kadra attēls, kura malu attiecība nosaka izvades kanvas proporcijas. Maksimālai vizuālajai konsekvencei izmantojiet retro 3D vai zemas poligonalitātes stila mākslas darbu. |
| `duration` |  | integer | no | `5` | 5 – 15 | Vēlamais video garums sekundēs. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Malu attiecība, kas tiek izmantota, ģenerējot tikai no teksta. Neietekmē rezultātu, ja ir padots image_url. |
| `seed` |  | integer \| null | no |  |  | Nejaušības sākumvērtība; ja tā nav norādīta, sākumvērtība tiek izvēlēta automātiski. |

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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/styles/low-poly?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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
let res = await fetch(API + "/run/minimax/h3-max/styles/low-poly?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3-max/styles/low-poly", 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/styles/low-poly",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
