# Topaz Denoise Video API

> Αφαίρεση θορύβου από βίντεο με τέσσερα μοντέλα Nyx, ρυθμιζόμενα επίπεδα θορύβου, συμπίεσης και halos, με προαιρετική αναβάθμιση

Καθαρίζει τον θόρυβο από το βίντεο στο `video_url`. Το `model` μπορεί να είναι Nyx, Nyx Fast, Nyx XL ή Nyx HF. Οι προαιρετικές τιμές `noise`, `compression` και `halo` (0 έως 1) ρυθμίζουν λεπτομερώς τη μείωση και το `upscale_factor` (1 έως 4) μπορεί να μεγεθύνει την έξοδο· το 1 διατηρεί την ανάλυση της πηγής. Το `H264_output` αντικαθιστά τον προεπιλεγμένο κωδικοποιητή H265.

## 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 βίντεο πηγής για αφαίρεση θορύβου. |
| `model` |  | enum (string) | no | `Nyx` | `Nyx`, `Nyx Fast`, `Nyx XL`, `Nyx HF` | Επιλογή μοντέλου αποθορυβοποίησης: για ακραίο θόρυβο χρησιμοποιήστε το Nyx XL, για ακριβή αποθορυβοποίηση έτοιμη για pipeline χωρίς αναβάθμιση ανάλυσης χρησιμοποιήστε το Nyx HF. Το Nyx δίνει προτεραιότητα στην ποιότητα και τη διατήρηση υφής, ενώ το Nyx Fast προτιμά την ταχύτητα έναντι της ποιότητας για επεξεργασία μεγάλου όγκου. |
| `upscale_factor` |  | number | no | `1` | 1 – 4 | Προαιρετικός πολλαπλασιαστής ανάλυσης μαζί με την αποθορυβοποίηση, όπου το 1.0 αφήνει αμετάβλητες τις διαστάσεις της πηγής αντί να κάνει αναβάθμιση. |
| `noise` |  | number \| null | no |  | 0 – 1 | Ισχύς μείωσης θορύβου, από 0.0 έως 1.0. Το μοντέλο καθορίζει την προεπιλογή. |
| `compression` |  | number \| null | no |  | 0 – 1 | Ισχύς αφαίρεσης τεχνουργημάτων συμπίεσης, από 0.0 έως 1.0. Το μοντέλο καθορίζει την προεπιλογή. |
| `halo` |  | number \| null | no |  | 0 – 1 | Ισχύς μείωσης φωτοστέφανων, από 0.0 έως 1.0. Το μοντέλο καθορίζει την προεπιλογή. |
| `H264_output` |  | boolean | no | `false` |  | Καθορίζει αν το βίντεο εξόδου χρησιμοποιεί κωδικοποίηση H264 αντί για την προεπιλεγμένη H265. |

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.
