# Flashvsr API

> مكبّر للفيديو يوسّع اللقطات بعامل من 1 إلى 4، مع تمرير صوتي اختياري

يكبّر فيديو من `video_url` باستخدام `upscale_factor` بين 1 و4 (الافتراضي 2). تشمل الخيارات `color_fix` و`preserve_audio` لنسخ المسارات الصوتية الأصلية، و`acceleration` بقيم regular أو high أو full. يمكن أن يكون الإخراج X264 mp4 أو VP9 webm أو ProRes 4444 mov أو GIF، مع `output_quality` من low إلى maximum.

- Model id: `flashvsr/upscale/video`
- Made by: Open model
- Category: Upscale
- Output: video
- Price per megapixel of your output video: $0.0005 / megapixel of output video (cheapest run $0.001 (1 API credit))
- Run: `POST https://api.doitong.ru/v1/run/flashvsr/upscale/video`
- Quote: `POST https://api.doitong.ru/v1/quote/flashvsr/upscale/video`
- Docs page: https://doitong.com/ar/developers/models/flashvsr/upscale/video

## Pricing

Price: **$0.0005 / megapixel of output video**. Price per megapixel of your output 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 $0.553 = 553 API credits (1105.92 MP output video × $0.0005).

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/flashvsr/upscale/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 |
|---|---|---|---|---|---|---|
| `upscale_factor` |  | number | no | `2` | 1 – 4 | معامل القياس لتكبير الدقة. |
| `seed` |  | integer \| null | no |  |  | البذرة العشوائية المستخدمة أثناء التوليد. |
| `video_url` | `video` | string (video URL) | yes |  |  | فيديو المصدر المراد تكبير دقته. |
| `acceleration` |  | enum (string) | no | `regular` | `regular`, `high`, `full` | اختر مقدار تسريع فك ترميز VAE، إذ يتيح التسريع الأكبر أيضًا دعم فيديوهات أطول. توازن الأوضاع بين الجودة والسرعة: يوفّر regular أفضل جودة، بينما يُعد full الأسرع، ويقدم high توازنًا. |
| `color_fix` |  | boolean | no | `true` |  | يمكّن تصحيح الألوان. |
| `quality` |  | integer | no | `70` | 0 – 100 | إعداد تداخل البلاطات للمزج، ويتراوح من 0 إلى 100 لمنع تشوهات الشبكة. لفيديوهات الدقة العالية، يوصى بالقيمة 70–85؛ وللمعالجة الأسرع، استخدم 50–70. تؤدي زيادة الإعداد إلى تحسين الجودة بإضافة مزيد من التداخل. |
| `preserve_audio` |  | boolean | no | `false` |  | خيار الاحتفاظ بالصوت الذي يستخدم FFmpeg، حيثما أمكن، لتضمين مسارات الصوت المصدر في الفيديو ذي الدقة المكبرة. |
| `output_format` |  | enum (string) | no | `X264 (.mp4)` | `X264 (.mp4)`, `VP9 (.webm)`, `PRORES4444 (.mov)`, `GIF (.gif)` | تنسيق الفيديو الناتج. |
| `output_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | إعداد جودة الفيديو الناتج. |
| `output_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | الوضع المستخدم لكتابة الفيديو الناتج. |
| `enable_safety_checker` |  | boolean | no | `true` |  | يمكن تخفيف الفحص بضبط القيمة على false، شريطة أن يكون المستدعي مخولًا بذلك. |

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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "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/flashvsr/upscale/video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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/flashvsr/upscale/video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "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 = {
    "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/flashvsr/upscale/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": "flashvsr/upscale/video",
      "input": {
        "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.
