# Flashvsr API

> Povećavač razlučivosti videozapisa koji povećava snimku faktorom od 1 do 4, uz neobavezno prosljeđivanje zvuka

Povećava razlučivost videa iz `video_url` pomoću `upscale_factor` između 1 i 4 (zadano 2). Mogućnosti uključuju `color_fix`, `preserve_audio` za kopiranje izvornih zvučnih zapisa i `acceleration` vrijednosti regular, high ili full. Izlaz može biti X264 mp4, VP9 webm, ProRes 4444 mov ili GIF, uz `output_quality` od low do 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.com/v1/run/flashvsr/upscale/video`
- Quote: `POST https://api.doitong.com/v1/quote/flashvsr/upscale/video`
- Docs page: https://doitong.com/hr/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.com/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 | Množitelj skaliranja za povećanje razlučivosti. |
| `seed` |  | integer \| null | no |  |  | Nasumični seed korišten tijekom generiranja. |
| `video_url` | `video` | string (video URL) | yes |  |  | Izvorni video za povećanje razlučivosti. |
| `acceleration` |  | enum (string) | no | `regular` | `regular`, `high`, `full` | Odaberite koliko ubrzati dekodiranje VAE-a; veće ubrzanje podržava i dulje videozapise. Načini predstavljaju kompromis između kvalitete i brzine: regular daje najbolju kvalitetu, full je najbrži, a high pruža ravnotežu. |
| `color_fix` |  | boolean | no | `true` |  | Omogućuje ispravljanje boja. |
| `quality` |  | integer | no | `70` | 0 – 100 | Postavka preklapanja pločica za stapanje, u rasponu od 0 do 100, radi sprječavanja artefakata mreže. Za videozapise visoke razlučivosti preporučuje se 70–85; za bržu obradu upotrijebite 50–70. Povećanjem postavke kvaliteta se poboljšava dodavanjem preklapanja. |
| `preserve_audio` |  | boolean | no | `false` |  | Opcija zadržavanja zvuka koja, gdje je moguće, upotrebljava FFmpeg za uključivanje izvornih zvučnih zapisa u video povećane razlučivosti. |
| `output_format` |  | enum (string) | no | `X264 (.mp4)` | `X264 (.mp4)`, `VP9 (.webm)`, `PRORES4444 (.mov)`, `GIF (.gif)` | Format rezultirajućeg videa. |
| `output_quality` |  | enum (string) | no | `high` | `low`, `medium`, `high`, `maximum` | Postavka kvalitete rezultirajućeg videa. |
| `output_write_mode` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `small` | Način upotrijebljen za zapisivanje dobivenog videa. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Provjera se može ublažiti postavljanjem na false, ako je pozivatelj ovlašten. |

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.com/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.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/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.com/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.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": "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.
