# Topaz Upscale Video Generative API

> Generativen Video-Upscaler mat auswielbare Starlight-Modeller, geduecht fir kompriméiert oder archivéiert Footage

Verbessert a vergréissert Video mat diffusion-baséierte Starlight-Modeller, ausgewielt iwwer `model`: Precise 2.6, HQ, Mini, Sharp oder Fast 2. `upscale_factor` geet vun 1 bis 4, an `target_fps` (16-60) aktivéiert Frame-Interpolatioun, wann de Wäert vun der Quell ofwäicht. `softness` (1-5) gëllt nëmme fir Starlight Precise 2.6. Den Output-Codec ass H265 oder op Ufro H264.

- Model id: `topaz/upscale/video/generative`
- Made by: Topaz Labs
- Category: Upscale
- Output: video
- Price per second of your input video: from $0.06 / second of input video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.ru/v1/run/topaz/upscale/video/generative`
- Quote: `POST https://api.doitong.ru/v1/quote/topaz/upscale/video/generative`
- Docs page: https://doitong.com/lb/developers/models/topaz/upscale/video/generative

## Pricing

Price: **from $0.06 / second of input video** (the lowest tier; the quote prices your exact input). 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.

Price by tier:

- Starlight Fast 2, up to 1080p: $0.06 / second of input video
- up to 1080p: $0.12 / second of input video
- Starlight Fast 2, up to 1080p, frame rate: $0.12 / second of input video
- Starlight Fast 2, 4K: $0.13 / second of input video
- Starlight Fast 2, above 4K: $0.2311 / second of input video
- up to 1080p, frame rate: $0.24 / second of input video
- 4K: $0.255 / second of input video
- Starlight Fast 2, 4K, frame rate: $0.26 / second of input video
- above 4K: $0.4533 / second of input video
- Starlight Fast 2, above 4K, frame rate: $0.4622 / second of input video
- 4K, frame rate: $0.51 / second of input video
- above 4K, frame rate: $0.9067 / second of input video

The full example input below costs $2.60 = 2600 API credits (10 s input video × $0.255 (4K), rounded up to the next $0.10).

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/topaz/upscale/video/generative` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL vum Quellvideo fir Upscaling. |
| `model` |  | enum (string) | no | `Starlight Precise 2.6` | `Starlight Precise 2.6`, `Starlight HQ`, `Starlight Mini`, `Starlight Sharp`, `Starlight Fast 2` | Auswiel vum generativen Diffusiounsmodell fir d'Videoverbesserung. Fir Archivrestauratioun benotzt Starlight Mini; fir séier Restauratioun mat schaarfen Detailer Starlight Sharp; fir maximal Qualitéit aus héich opléistem Footage Starlight HQ; a fir méi realistesche AI-generéierte Video Starlight Precise 2.6. Ënnert den Diffusiouns-Upscaler ass Starlight Fast 2 dee séiersten a bëllegsten. |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | Video-Skaléierungsmultiplizéierer; 2.0 verduebelt béid Frame-Dimensiounen. |
| `target_fps` |  | integer \| null | no |  | 16 – 60 | Zil-Output-Frame-Rate; wann se der Quell-FPS entsprécht, bleift d'Interpolatioun ausgeschalt, an nëmmen eng aner FPS aktivéiert se. |
| `softness` |  | number \| null | no |  | 1 – 5 | Weichheetsastellung, nëmme fir Starlight Precise 2.6 verfügbar, mam Standard wann ewechgelooss. Wielt 1 fir de schäerfsten Output oder 5 fir de mëllsten. |
| `H264_output` |  | boolean | no | `false` |  | Steiert, ob den Output-Video H264-Encoding amplaz vum Standard-H265 benotzt. |

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/topaz/upscale/video/generative?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/topaz/upscale/video/generative?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/topaz/upscale/video/generative", 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": "topaz/upscale/video/generative",
      "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.
