Agiunta effects da tun sincronisads cun l'acziun visibla e returna in mp4 cun l'audio inclus, ensemen cun il tun generà sco datoteca separada. Utilisescha `prompt` per ina direcziun generala u `segments` per descripziuns per intervall temporal. `audio_format` fixescha il format da la datoteca separada (wav, mp3, aac u flac), e `keep_speech_vocal` mantegna la tschantscha originala.

- 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`

## 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 furnì cun upload da datoteca u URL public per la generaziun da tuns, cun sia durada che determinescha la lunghezza da l'audio generà. |
| `prompt` |  | string \| null | no |  |  | Indicaziun opziunala dal tun utilisada en tut las scenas enstagl da la titulaziun automatica dal video. Descrivai l'audio giavischà, u laschai la valur vida per utilisar las titulaziuns automaticas. |
| `segments` |  | array of object {start, end, prompt} \| null | no |  |  | Divisiuns manualas opziunalas da las scenas, spezifitgadas sco intervals da temp cun descripziuns individualas dals tuns; ina valur vida utilisescha enstagl la detecziun automatica da scenas. |
| `segments[].start` |  | number | no | `0` | ≥ 0 | L'inizialisaziun dal segment sto esser 0 per l'emprim segment. Tut ils temps d'inizialisaziun èn mesirads en secunda relativamain al cumenzament dal video. |
| `segments[].end` |  | number | no | `0` | ≥ 0 | Posiziun finala dal segment en secunda, limitada da la durada dal video per l'ultim segment. Per mintga segment precedent sto ella coincidir cun la posiziun d'inizialisaziun dal segment suandant, uschia ch'i na dat nagins spazis vids u surposiziuns. |
| `segments[].prompt` |  | string | no | `` |  | Descripziun dals effects da tun u da la foley dal segment. |
| `audio_format` |  | enum (string) | no | `aac` | `wav`, `mp3`, `aac`, `flac` | Format d'audio independent, selecziunabel sco wav, mp3, aac u flac, cun aac sco standard. Questa selecziun na mida betg la codaziun d'audio dal video, che è adina AAC. |
| `keep_speech_vocal` |  | boolean | no | `false` |  | Interrupter per mantegnair pleds/vusch che influenzescha ils outputs d'audio e video; dischavà per standard, lascha el en il resultat mo il tun generà. L'activaziun utilisescha la separaziun da funtaunas musicalas per isoltar la vusch originala, stizza la musica e l'atmosfera originalas e maschaida il tun generà cun la registraziun da vusch invariada, adattond il livel a la vusch. |

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.
