# Sonilo V1.1 Video to Video Sound Effects API

> Mengembalikan video input dengan kesan bunyi yang dijana dicampurkan, serta kesan tersebut sebagai fail berasingan

Menambah kesan bunyi yang diselaraskan dengan aksi yang kelihatan dan mengembalikan mp4 dengan audio disertakan, bersama bunyi yang dijana sebagai fail berasingan. Gunakan `prompt` untuk arahan umum atau `segments` untuk perihalan setiap julat masa. `audio_format` menetapkan format fail berasingan (wav, mp3, aac atau flac), manakala `keep_speech_vocal` mengekalkan pertuturan asal.

- Model id: `sonilo/v1.1/video-to-video-sound-effects`

- Category: Video to Audio
- Output: video
- Price per second of your input video: $0.009 / second of input video (cheapest run $0.009 (9 API credits))
- Run: `POST https://api.doitong.ru/v1/run/sonilo/v1.1/video-to-video-sound-effects`
- Quote: `POST https://api.doitong.ru/v1/quote/sonilo/v1.1/video-to-video-sound-effects`
- Docs page: https://doitong.com/ms/developers/models/sonilo/v1.1/video-to-video-sound-effects

## Pricing

Price: **$0.009 / second of input video**. 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.

The full example input below costs $0.09 = 90 API credits (10 s input video × $0.009).

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/sonilo/v1.1/video-to-video-sound-effects` 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 |  |  | Video yang dibekalkan melalui muat naik fail atau URL awam untuk penjanaan bunyi, dengan tempohnya menentukan panjang audio yang dijana. |
| `prompt` |  | string \| null | no |  |  | Panduan bunyi pilihan yang digunakan merentas semua adegan dan bukannya kapsyenan video automatik. Huraikan audio yang dikehendaki, atau biarkan nilai kosong untuk menggunakan kapsyen automatik. |
| `segments` |  | array of object {start, end, prompt} \| null | no |  |  | Pembahagian adegan manual pilihan, dinyatakan sebagai julat masa dengan perihalan bunyi individu; nilai kosong sebaliknya menggunakan pengesanan adegan automatik. |
| `segments[].start` |  | number | no | `0` | ≥ 0 | Permulaan segmen mesti 0 untuk segmen pertama. Semua masa mula diukur dalam saat relatif kepada permulaan video. |
| `segments[].end` |  | number | no | `0` | ≥ 0 | Kedudukan akhir segmen dalam saat, dibatasi oleh tempoh video untuk segmen terakhir. Bagi setiap segmen terdahulu, kedudukan ini mesti bertepatan dengan kedudukan mula segmen berikutnya supaya tiada jurang atau pertindihan. |
| `segments[].prompt` |  | string | no | `` |  | Perihalan kesan bunyi atau foley segmen. |
| `audio_format` |  | enum (string) | no | `aac` | `wav`, `mp3`, `aac`, `flac` | Format audio kendiri, boleh dipilih sebagai wav, mp3, aac atau flac, dengan aac digunakan secara lalai. Pilihan ini tidak mengubah pengekodan audio video, yang sentiasa AAC. |
| `keep_speech_vocal` |  | boolean | no | `false` |  | Suis pengekalan pertuturan/vokal yang mempengaruhi kedua-dua output audio dan video; dilumpuhkan secara lalai, ia meninggalkan hanya bunyi yang dijana dalam hasil. Mendayakannya menggunakan pemisahan sumber muzik untuk mengasingkan vokal sumber, membuang muzik dan suasana asal, serta mencampurkan bunyi yang dijana dengan rakaman vokal yang tidak berubah, dengan arasnya dipadankan dengan suara. |

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/sonilo/v1.1/video-to-video-sound-effects?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/sonilo/v1.1/video-to-video-sound-effects?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/sonilo/v1.1/video-to-video-sound-effects", 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": "sonilo/v1.1/video-to-video-sound-effects",
      "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.
