# Topaz Video Upscale API

> 最大4倍に対応し、任意でフレームレート変換も行えるTopaz Labsの動画アップスケーラー兼復元ツール。

TopazのProteus、Iris、Dione、Artemis、Gaia、Rhea、Theiaモデルで動画をアップスケール・復元します。 古いDVやテレビ映像からアニメーションまで対応します。ディテール復元、ノイズ、ハロー、圧縮、粒子を制御でき、 16〜60 fpsの目標フレームレートも任意で指定できます。

- Model id: `topaz/upscale/video/precision`
- Made by: Topaz Labs
- Category: Upscale
- Output: video
- Price per second of your input video: from $0.00667 / second of input video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/topaz/upscale/video/precision`
- Quote: `POST https://api.doitong.com/v1/quote/topaz/upscale/video/precision`
- Docs page: https://doitong.com/ja/developers/models/topaz/upscale/video/precision

## Pricing

Price: **from $0.00667 / 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:

- 720p: $0.00667 / second of input video
- 1080p: $0.0133 / second of input video
- 720p, frame rate: $0.0133 / second of input video
- 1080p, frame rate: $0.0267 / second of input video
- 4K: $0.0517 / second of input video
- above 4K: $0.0919 / second of input video
- 4K, frame rate: $0.1033 / second of input video
- above 4K, frame rate: $0.1837 / second of input video

The full example input below costs $0.60 = 600 API credits (10 s input video × $0.051667 (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.com/v1/quote/topaz/upscale/video/precision` 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 |  |  | アップスケール対象のソース動画 URL。 |
| `model` |  | enum (string) | no | `Proteus` | `Proteus`, `Proteus Natural`, `Iris`, `Iris Low Quality`, `Dione DV`, `Dione TV`, `Dione Robust`, `Dione Dehalo`, `Dione Robust Dehalo`, `Artemis High Quality`, `Artemis Medium Quality`, `Artemis Low Quality`, `Artemis Strong Halo`, `Artemis Medium Halo`, `Artemis Aliasing & Moire`, `Gaia HQ`, `Gaia CG`, `Gaia 2`, `Rhea`, `Theia Fine Tune Detail`, `Theia Fine Tune Fidelity` | 生成を行わない精密補正モデル。Theia は忠実度とディテールを手動制御し、Rhea は内部 4x パスで細部を最大化します。復元には、劣化映像のシャープ化とノイズ除去に Artemis、古い映像やインターレース素材のデインターレースに Dione、顔の復元に Iris を使用します。現実世界の映像の多くには Proteus が適し、Proteus Natural はより柔らかな代替です。Gaia は高品質映像と CG を改善し、Gaia 2 はアニメーションを 2x アップスケールします。 |
| `upscale_factor` |  | number | no | `2` | 1 – 4 | 動画の拡大倍率。2.0 は両方のフレーム寸法を 2 倍にします。 |
| `target_fps` |  | integer \| null | no |  | 16 – 60 | 目標とする出力フレームレート。ソース FPS と一致すると補間は無効になり、異なる FPS の場合のみ有効になります。 |
| `compression` |  | number \| null | no |  | 0 – 1 | 0.0〜1.0 の圧縮アーティファクト除去強度。デフォルトはモデルによって決まります。 |
| `noise` |  | number \| null | no |  | 0 – 1 | 0.0〜1.0 のノイズ低減強度。デフォルトはモデルによって決まります。 |
| `halo` |  | number \| null | no |  | 0 – 1 | 0.0〜1.0 のハロー低減強度。デフォルトはモデルによって決まります。 |
| `grain` |  | number \| null | no |  | 0 – 0.1 | 0.0〜0.1 のフィルムグレイン量。デフォルトはモデルによって異なります。 |
| `recover_detail` |  | number \| null | no |  | 0 – 1 | 0.0〜1.0 の元ディテール復元強度。値を上げるとソースのディテールをより多く保持します。 |
| `H264_output` |  | boolean | no | `false` |  | 出力動画でデフォルトの H265 ではなく H264 エンコードを使用するかどうかを制御します。 |

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": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "upscale_factor": 2
}
```

## 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/topaz/upscale/video/precision?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "upscale_factor": 2
  }'

# 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/topaz/upscale/video/precision?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "upscale_factor": 2
  }),
});
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": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "upscale_factor": 2,
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/topaz/upscale/video/precision", 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": "topaz/upscale/video/precision",
      "input": {
        "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "upscale_factor": 2
      },
      "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.
