# Kling O3 Edit Video [Standard] API

> ویرایش ویدیوی O3 در سطح Standard از روی پرامپت، با ارجاع‌های تصویری و عنصری و حفظ صوت

ویدیوی ورودی را با promptی که منبع را با @Video1 مشخص می‌کند، تغییر می‌دهد. `video_url` باید .mp4 یا .mov، به طول 3-15 ثانیه، ابعاد 720-3840px و حداکثر 200MB باشد. برای هدایت ظاهر، `image_urls` یا `elements` را با حداکثر 4 مورد در مجموع اضافه کنید. `keep_audio` به‌صورت پیش‌فرض روشن است تا صدای اصلی حفظ شود.

- Model id: `kling-video/o3/standard/video-to-video/edit`
- Made by: Kling
- Category: Video to Video
- Output: video
- Price per second of your input video: $0.126 / second of input video (cheapest run $0.126 (126 API credits))
- Run: `POST https://api.doitong.ru/v1/run/kling-video/o3/standard/video-to-video/edit`
- Quote: `POST https://api.doitong.ru/v1/quote/kling-video/o3/standard/video-to-video/edit`
- Docs page: https://doitong.com/fa/developers/models/kling-video/o3/standard/video-to-video/edit

## Pricing

Price: **$0.126 / 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 $1.26 = 1260 API credits (10 s input video × $0.126).

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/kling-video/o3/standard/video-to-video/edit` 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 |
|---|---|---|---|---|---|---|
| `enable_safety_checker` |  | boolean | no | `true` |  | بررسی‌های ایمنی فقط با مجوز حساب قابل غیرفعال‌سازی هستند؛ درخواست‌های بدون مجوز همیشه بررسی می‌شوند. |
| `prompt` |  | string | yes |  | ≤ 2500 characters | دستورهای متنی برای تولید ویدیو. برای ارجاع به ویدیوی مرجع از @Video1 استفاده کنید. |
| `video_url` | `video` | string (video URL) | yes |  |  | URL اشاره‌کننده به ویدیوی مرجع با قالب .mp4 یا .mov و حداکثر اندازه 200MB. هر دو بُعد باید بین 720px و 3840px، نرخ فریم بین 23.0–60.0 FPS و مدت ویدیو بین 3–15 ثانیه (حداکثر 15.05 ثانیه) باشد. |
| `image_urls` | `images` | array of image URL \| null | no |  |  | تصاویر هدایت‌کننده سبک یا ظاهر که در پرامپت با @Image1، @Image2 و به همین ترتیب ارجاع داده می‌شوند. هنگام استفاده از ورودی ویدیو، مجموع عناصر و تصاویر مرجع نمی‌تواند بیشتر از 4 مورد باشد. اندازه هر فایل حداکثر 50 MB است؛ عرض و ارتفاع هرکدام باید حداقل 300 px و نسبت تصویر بین 0.40 و 2.50 باشد. |
| `keep_audio` |  | boolean | no | `true` |  | مشخص می‌کند صوت اصلی ویدیوی مرجع حفظ شود یا خیر. |
| `elements` |  | array of object {frontal_image_url, reference_image_urls} \| null | no |  |  | شخصیت‌ها یا اشیایی که باید گنجانده شوند و در پرامپت با @Element1 و @Element2 ارجاع داده می‌شوند. |
| `elements[].frontal_image_url` |  | string (image URL) \| null | no |  |  | تصویر روبه‌رو که نمای اصلی عنصر را نشان می‌دهد. اندازه فایل نباید بیشتر از 50 MB باشد؛ عرض و ارتفاع هرکدام باید حداقل 300px و نسبت تصویر بین 0.40 و 2.50 باشد. |
| `elements[].reference_image_urls` |  | array of image URL \| null | no |  |  | 1–3 تصویر مرجع اضافی از زوایای مختلف ارائه کنید. نسبت تصویر هر تصویر باید بین 0.40 و 2.50 باشد، هر دو بُعد آن حداقل 300px و اندازه فایل حداکثر 50.0MB باشد. |
| `shot_type` |  | string | no | `customize` |  | حالت استفاده‌شده برای تولید ویدیوهای چندنما. |

File parameters (`video`, `images`) 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/kling-video/o3/standard/video-to-video/edit?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/kling-video/o3/standard/video-to-video/edit?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/kling-video/o3/standard/video-to-video/edit", 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": "kling-video/o3/standard/video-to-video/edit",
      "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.
