# Krea Wan 14B API

> ٹیکسٹ پرامپٹ اور طاقت کے کنٹرول کے ذریعے ان پٹ ویڈیو کا انداز تبدیل کرتا ہے؛ صرف 16:9 اور 480p سورس

ٹیکسٹ `prompt` اور سورس `video_url` کے ذریعے موجودہ کلپ میں ترمیم کرتا ہے۔ ان پٹ 480p میں 16:9 اور 16fps پر 1000 فریم سے کم ہونا چاہیے۔ `strength` کی حد 0.01 سے 1 ہے: کم قدریں اصل کے قریب رہتی ہیں، جبکہ 1 ویڈیو کو مکمل طور پر دوبارہ بناتا ہے۔ اختیاری `enable_prompt_expansion` زبان کے ماڈل سے پرامپٹ کو بہتر بناتا ہے، اور `seed` نتیجہ مقرر کرتا ہے۔

- Model id: `krea-wan-14b/video-to-video`
- Made by: Krea
- Category: Video to Video
- Output: video
- Price per second of your input video: $0.025 / second of input video (cheapest run $0.025 (25 API credits))
- Run: `POST https://api.doitong.ru/v1/run/krea-wan-14b/video-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/krea-wan-14b/video-to-video`
- Docs page: https://doitong.com/ur/developers/models/krea-wan-14b/video-to-video

## Pricing

Price: **$0.025 / second of input video**. Price per second of your input video: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.469 = 469 API credits (18.75 s input video × $0.025).

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/krea-wan-14b/video-to-video` 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 |  |  | ویڈیو سے ویڈیو تخلیق کی رہنمائی کرنے والا پرامپٹ۔ |
| `strength` |  | number | no | `0.85` | 0.01 – 1 | ویڈیو سے ویڈیو denoising کی طاقت؛ 1.0 پر مکمل تخلیق نو اور 0.0 پر ماخذ میں کوئی تبدیلی نہیں ہوتی۔ |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | بڑے ماڈل کو تفصیلات کے ساتھ پرامپٹ بہتر بنانے کی اجازت دیں۔ یہ توسیع فعال کرنے سے پرامپٹ کا مفہوم تبدیل نہیں ہوتا۔ |
| `video_url` | `video` | string (video URL) | yes |  |  | تخلیق کے لیے ماخذ ویڈیو URL، جو فی الحال 480p آؤٹ پٹ اور 16:9 aspect ratio تک محدود ہے۔ آؤٹ پٹ فریم کی تعداد 6 جمع 12 کے صحیح عددی مضرب کے مطابق ہوتی ہے، مثلاً 18، 30 یا 42؛ ان پٹ 16 fps پر 1000 فریم سے کم رہنا چاہیے۔ |
| `seed` |  | integer \| null | no |  |  | ویڈیو سے ویڈیو تخلیق میں استعمال ہونے والی seed ویلیو۔ |
| `enable_safety_checker` |  | boolean | no | `true` |  | false سیٹ کر کے اسکریننگ نرم کی جا سکتی ہے، بشرطیکہ کال کرنے والا مجاز ہو۔ |

File parameters (`video`) 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",
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

## 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/krea-wan-14b/video-to-video?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",
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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

```javascript
const API = "https://api.doitong.ru/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/krea-wan-14b/video-to-video?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",
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }),
});
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.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",
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/krea-wan-14b/video-to-video", 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.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": "krea-wan-14b/video-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
