# MiniMax H3 Image to Video LoRA API

> Özne tutarlılığı için 1 ila 3 LoRA adaptörü ve isteğe bağlı son kareyle sabit görüntüyü ilk kare olarak canlandırır

Bir ila üç LoRA adaptörü kullanarak eğitilmiş bir öznenin veya tarzın tutarlılığını koruyarak sabit görüntüyü sesli video klibine dönüştürür. `image_url` değerini açılış karesi olarak, isteğe bağlı olarak `end_image_url` değerini kapanış karesi olarak gönderin. Uzunluk 5 ile 15 saniye arasındadır; `resolution` 480P, 768P, 2K veya 4K olabilir; 2K ve 4K, 768P tabanını yükseltir. `target_audio_url` üzerinden bir ses klibi sağlanabilir.

## Pricing

Price: **from $0.0625 / second (5 s ≈ $0.313)** (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: $0.075 (75 API credits) / second
- When `resolution` = 2K: $0.1625 (162.5 API credits) / second
- When `resolution` = 4K: $0.20 (200 API credits) / second

The full example input below costs $0.813 = 813 API credits (5 s × 162.5 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.ru/v1/quote/minimax/h3/image-to-video/lora` 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 – 50000 characters | Video üretimi için metin talimatları. |
| `duration` |  | integer | no | `5` | 5 – 15 | Video uzunluğu, saniye cinsinden ölçülür. |
| `resolution` |  | enum (string) | no | `2K` | `480P`, `768P`, `2K`, `4K` | Üretilen videonun çözünürlüğünü seçin; 2K ve 4K, 768P tabanının yükseltilmesiyle elde edilir. Bunun yerine 480P veya 768P seçmek yerel üretim kullanır. |
| `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 \| null | no | `balanced` |  | Üretim öncesi istem yeniden yazma çabası: yaklaşık 30 saniyeye kadar süren daha zengin bir istem için 'quality', yaklaşık bir saniyede sonuç için 'fast' seçin. 'balanced' ile seçim istek başına yapılır; 'disabled' genişletmeyi kapatır. |
| `target_audio_url` |  | string (audio URL) \| null | no |  | ≥ 1 characters | HTTP(S) URL'si veya base64 veri URI'si üzerinden sağlanan isteğe bağlı alternatif film müziği; klip en az 2 saniye sürmeli ve 15 MB'tan büyük olmamalıdır. Sağlanan ses, değişmemiş oynatma hızıyla üretilen film müziğinin yerini alır: fazla süre sondan kaldırılır, daha kısa kliplere videoyla eşleşmesi için sessizlik dolgusu eklenir. Olağandışı yüksek örnekleme hızlarında 96 kHz'e yeniden örnekleme yapılabilir. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | Açılış karesini ve çıktı tuvalini tanımlayan isteğe bağlı görsel URL'si. Yalnızca end_image_url sağlanırsa tuvali bunun kapanış karesi belirler. Her iki görsel de yoksa üretim, varsayılan 16:9 en-boy oranıyla metinden videoya kullanır. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | Başlangıç görseli olmadan da kullanılabilen isteğe bağlı son-kare görsel URL'si. Yalnızca son kare anahtar karesi modunda çıktı tuvalini bu görsel belirler. |
| `loras` |  | array of object {path, weight_name, scale} | yes |  | 1 – 3 items | Dönüştürücüye uygulanacak LoRA bağdaştırıcı listesi. |
| `loras[].path` |  | string | yes |  |  | LoRA ağırlıklarının konumu; URL veya owner/repo biçiminde HuggingFace depo ID'si olarak verilir. |
| `loras[].weight_name` |  | string \| null | no |  |  | `path` ile tanımlanan bir HuggingFace deposundaki birden fazla LoRA arasından seçim yapmak için yalnızca LoRA ağırlık dosya adını belirtin. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | LoRA etki gücü, 0.0 ile 4.0 arasında değişir. |

File parameters (`target_audio_url`, `image`, `end_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",
  "loras": [
    {
      "path": "https://example.com/your-file.safetensors"

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "loras": [
    {
      "path": "https://example.com/your-file.safetensors"
    }

```

## 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.ru/v1/run/minimax/h3/image-to-video/lora?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",
    "loras": [
      {
        "path": "https://example.com/your-file.safetensors"
      }
    ]
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

### Python

```python
import os
import requests

API = "https://api.doitong.ru/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",
    "loras": [
        {
            "path": "https://example.com/your-file.safetensors",
        },
    ],

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3/image-to-video/lora", 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":

print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.ru/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/image-to-video/lora",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "loras": [
          {
            "path": "https://example.com/your-file.safetensors"
          }
        ]
      },
      "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. |
