# Wan-2.1 Image-to-Video with LoRAs API

> המרת תמונה לווידאו Wan 2.1 עם תמיכה ב־LoRA מותאם אישית, נגינה הפוכה אופציונלית ומצב turbo

מנפיש תמונת קלט (`image_url`) לפי `prompt`, עם משקלי LoRA מותאמים אישית דרך `loras`. אפשרויות נוספות כוללות `reverse_video` לנגינה לאחור של הקטע ו־`turbo_mode` ליצירה מהירה יותר. הרזולוציה היא 480p או 720p, `num_frames` הוא 81-100, קצב הפריימים 5-24, ויחס התצוגה auto, 16:9, 9:16 או 1:1.

- Model id: `wan-i2v-lora`
- Made by: Alibaba
- Category: Image to Video
- Output: video
- Price: $0.75 / video (cheapest run $0.75 (750 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan-i2v-lora`
- Quote: `POST https://api.doitong.com/v1/quote/wan-i2v-lora`
- Docs page: https://doitong.com/he/developers/models/wan-i2v-lora

## Pricing

Price: **$0.75 / video**. Billed once per generated video.

The full example input below costs $0.75 = 750 API credits (1 video × 750 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/wan-i2v-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 |  |  | הוראות טקסטואליות המנחות את יצירת הווידאו. |
| `negative_prompt` |  | string | no | `bright colors, overexposed, static, blurred details, subtitles, style, artwork, painting, picture, still, overall gray, worst quality, low quality, JPEG compression residue, ugly, incomplete, extra fingers, poorly drawn hands, poorly drawn faces, deformed, disfigured, malformed limbs, fused fingers, still picture, cluttered background, three legs, many people in the background, walking backwards` |  | הנחיה שלילית שהוחלה בעת יצירת וידאו. |
| `image_url` | `image` | string (image URL) | yes |  |  | כתובת URL של תמונת המקור, כאשר יחס הגובה-רוחב שנבחר קובע אם נדרש עיבוד מקדים: אי-התאמה מפעילה שינוי גודל ולאחריו חיתוך מרכזי. |
| `num_frames` |  | integer \| null | no | `81` | 81 – 100 | מספר הפריימים ליצירה, בטווח 81 עד 100 כולל. |
| `frames_per_second` |  | integer \| null | no | `16` | 5 – 24 | קצב הפריימים של הווידאו שנוצר, בפריימים לשנייה, בטווח 5 עד 24. |
| `seed` |  | integer \| null | no |  |  | Seed שהופך את היצירה לניתנת לשחזור. הגדרתו ל-None בוחרת Seed באקראי. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | רזולוציית וידאו הפלט, 480p או 720p. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 40 | מספר צעדי הדגימה, המאזן בין זמן עיבוד ארוך יותר לאיכות טובה יותר ככל שהמספר גדל. |
| `guide_scale` |  | number | no | `5` | 1 – 10 | עוצמת הנחיה ללא מסווג, המאזנת בין אובדן איכות אפשרי להתאמה קרובה יותר להנחיה ככל שהקנה מידה גדל. |
| `shift` |  | number | no | `5` | 1 – 10 | הגדרת ההסטה המוחלת בעת יצירת וידאו. |
| `enable_safety_checker` |  | boolean | no | `false` |  | מתג בדיקת בטיחות, שמצב הכיבוי שלו דורש הרשאת חשבון. ללא הרשאה זו, כל בקשה נבדקת ללא קשר להגדרה; true מפעיל את הבודק. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | שולט אם הרחבת ההנחיה מופעלת. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `auto`, `16:9`, `9:16`, `1:1` | יחס הרוחב לגובה של פלט הווידאו. |
| `loras` |  | array of object {path, weight_name, scale} | no | `[]` |  | משקלי LoRA המוחלים במהלך ההסקה. |
| `loras[].path` |  | string | yes |  |  | מיקום משקלי ה־LoRA, המצוין ככתובת URL או כנתיב. |
| `loras[].weight_name` |  | string \| null | no |  |  | שם משקל LoRA, נדרש רק כאשר מאגר Hugging Face מכיל יותר מקובץ safetensors אחד. נעשה בשם זה שימוש רק כאשר `path` מזהה מאגר כזה. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | מכפיל המוחל על משקל ה־LoRA לפני מיזוגו במודל הבסיס. |
| `reverse_video` |  | boolean | no | `false` |  | מתג היפוך וידאו; true הופך את כיוון ההפעלה. |
| `turbo_mode` |  | boolean | no | `true` |  | מתג ליצירת וידאו מהירה יותר. הפעלתו מקצרת את זמן היצירה ללא אובדן מורגש באיכות החזותית. |

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",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/wan-i2v-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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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/wan-i2v-lora?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

  }),
});
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",
    "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
r = requests.post(API + "/run/wan-i2v-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":
    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": "wan-i2v-lora",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
