# Topaz Denoise Video API

> Khử nhiễu video với bốn mô hình Nyx, điều chỉnh nhiễu, nén và quầng sáng, kèm tùy chọn nâng cấp

Khử nhiễu cho video tại `video_url`. `model` có thể là Nyx, Nyx Fast, Nyx XL hoặc Nyx HF. Các giá trị `noise`, `compression` và `halo` tùy chọn (0 đến 1) tinh chỉnh mức giảm nhiễu, còn `upscale_factor` (1 đến 4) có thể phóng lớn đầu ra; 1 giữ nguyên độ phân giải nguồn. `H264_output` thay codec H265 mặc định.

- Model id: `topaz/denoise/video`
- Made by: Topaz Labs
- Category: Video to Video
- Output: video
- Price per second of your input video: from $0.00333 / second of input video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/topaz/denoise/video`
- Quote: `POST https://api.doitong.com/v1/quote/topaz/denoise/video`
- Docs page: https://doitong.com/vi/developers/models/topaz/denoise/video

## Pricing

Price: **from $0.00333 / 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:

- Nyx Fast, 720p: $0.00333 / second of input video
- 720p: $0.00667 / second of input video
- Nyx Fast, 720p, frame rate: $0.00667 / second of input video
- Nyx Fast, 1080p: $0.00667 / second of input video
- 720p, frame rate: $0.0133 / second of input video
- 1080p: $0.0133 / second of input video
- Nyx Fast, 1080p, frame rate: $0.0133 / second of input video
- Nyx Fast, 4K: $0.0258 / second of input video
- 1080p, frame rate: $0.0267 / second of input video
- Nyx Fast, above 4K: $0.0459 / second of input video
- 4K: $0.0517 / second of input video
- Nyx Fast, 4K, frame rate: $0.0517 / second of input video
- above 4K: $0.0919 / second of input video
- Nyx Fast, above 4K, frame rate: $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 $0.10 = 100 API credits (10 s input video × $0.006667 (720p), 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/denoise/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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | URL video nguồn để loại bỏ nhiễu. |
| `model` |  | enum (string) | no | `Nyx` | `Nyx`, `Nyx Fast`, `Nyx XL`, `Nyx HF` | Lựa chọn mô hình khử nhiễu: với nhiễu cực mạnh, dùng Nyx XL; để khử nhiễu chính xác, sẵn sàng cho pipeline mà không nâng độ phân giải, dùng Nyx HF. Nyx ưu tiên chất lượng và giữ lại kết cấu, còn Nyx Fast ưu tiên tốc độ hơn chất lượng khi xử lý khối lượng lớn. |
| `upscale_factor` |  | number | no | `1` | 1 – 4 | Hệ số độ phân giải tùy chọn đi kèm khử nhiễu; 1.0 giữ nguyên kích thước nguồn thay vì nâng độ phân giải. |
| `noise` |  | number \| null | no |  | 0 – 1 | Cường độ giảm nhiễu, từ 0.0 đến 1.0. Mô hình xác định giá trị mặc định. |
| `compression` |  | number \| null | no |  | 0 – 1 | Cường độ loại bỏ hiện tượng nén, từ 0.0 đến 1.0. Mô hình xác định giá trị mặc định. |
| `halo` |  | number \| null | no |  | 0 – 1 | Cường độ giảm quầng sáng, từ 0.0 đến 1.0. Mô hình xác định giá trị mặc định. |
| `H264_output` |  | boolean | no | `false` |  | Kiểm soát việc video đầu ra sử dụng mã hóa H264 thay vì H265 mặc định. |

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/topaz/denoise/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/topaz/denoise/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/topaz/denoise/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": "topaz/denoise/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.
