# Sonilo V1.1 Video to Sound Effects API

> Býr til tímasett hljóðbrellur fyrir myndband og skilar þeim eingöngu sem hljóðskrá

Bætir við samstilltum hljóðbrellum út frá því sem gerist í myndbandinu á `video_url`. Valkvæður `prompt` stýrir hljóðinu og `segments` úthlutar aðskildum lýsingum á tímasvið. `audio_format` getur verið wav, mp3, aac eða flac. Þegar `keep_speech_vocal` er virkt er upprunalegt tal einangrað og haldið í blöndunni.

- Run: `POST https://api.doitong.ru/v1/run/sonilo/v1.1/video-to-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-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 |  |  | Myndband sem er gefið upp með skráarupphleðslu eða opinberri slóð til hljóðgerðar, þar sem lengd þess ákvarðar lengd myndaða hljóðsins. |
| `prompt` |  | string \| null | no |  |  | Valfrjálsar hljóðleiðbeiningar sem eru notaðar í öllum senum í stað sjálfvirkrar myndbandstextunar. Lýstu hljóðinu sem þú vilt eða skildu gildið eftir autt til að nota sjálfvirka textun. |
| `segments` |  | array of object {start, end, prompt} \| null | no |  |  | Valfrjáls handvirk senuskipting, tilgreind sem tímasvið með einstökum hljóðlýsingum; autt gildi notar sjálfvirka senugreiningu í staðinn. |
| `segments[].start` |  | number | no | `0` | ≥ 0 | Upphaf fyrsta hluta verður að vera 0. Allar upphafstímasetningar eru mældar í sekúndum frá byrjun myndbandsins. |
| `segments[].end` |  | number | no | `0` | ≥ 0 | Endastaða hluta í sekúndum, takmörkuð af lengd myndbandsins fyrir síðasta hlutann. Fyrir alla fyrri hluta verður hún að falla saman við upphafsstöðu næsta hluta svo engin bil eða skörun myndist. |
| `segments[].prompt` |  | string | no | `` |  | Lýsing á hljóðbrellum eða foley í hlutanum. |
| `audio_format` |  | enum (string) | no | `aac` | `wav`, `mp3`, `aac`, `flac` | Sjálfstætt hljóðsnið, sem hægt er að velja sem wav, mp3, aac eða flac, þar sem aac er sjálfgefið. Þetta val breytir ekki hljóðkóðun myndbandsins, sem er alltaf AAC. |
| `keep_speech_vocal` |  | boolean | no | `false` |  | Rofi fyrir varðveislu tals eða söngs sem hefur áhrif á bæði hljóð- og myndbandsúttak; sjálfgefið óvirkur, þannig að aðeins myndað hljóð verður eftir í niðurstöðunni. Þegar hann er virkjaður er aðgreining tónlistarheimilda notuð til að einangra upprunalega sönginn, upprunalegri tónlist og umhverfishljóði er fargað og myndað hljóð blandað við óbreytta upptöku raddarinnar með hljóðstyrk sem passar við röddina. |

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-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-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-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-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.
