# Sonilo V1.1 Video to Video Music API

> Returnerer inputvideoen med et genereret musikspor mixet ind og med valgfri bevarelse af tale

Behandler en video og leverer færdige mp4-filer med tilføjet musik. Valgfri `prompt` og `prompt_influence` (0 til 1) styrer stilen. `keep_speech_vocal` bevarer den oprindelige tale over musikken, som dæmpes under talen. `start_offset` og `duration` begrænser behandlingen til et segment på op til 600 sekunder, og `num_samples` giver 1 til 3 videoer.

## Pricing

Price: **$0.009 / second of output audio**. Price per second of your output audio: 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 output audio × $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-music` 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 |  |  | Offentligt tilgængelig HTTP- eller HTTPS-URL til videoen, der skal modtage et musikalsk score. |
| `keep_speech_vocal` |  | boolean | no | `false` |  | Bevarelse af tale/stemme i outputvideoen, som standard deaktiveret, så genereret musik erstatter det oprindelige soundtrack helt. Når den aktiveres, bruges musikkildeseparation til kun at udtrække vokalen og blande den over den genererede musik; automatisk ducking sænker musikken under tale. |
| `num_samples` |  | integer | no | `1` | 1 – 3 | Antal forskellige videoer med genererede scores, der skal produceres. |
| `prompt` |  | string \| null | no |  |  | Musikalsk stilvejledning, der valgfrit erstatter den prompt, som automatisk udledes af videoen. |
| `prompt_influence` |  | number | no | `0.5` | 0 – 1 | Styrke for prompt-overholdelse; øg den for et tættere match med tekstinstruktionen. |
| `start_offset` |  | number \| null | no |  | 0 – 600 | Valgfri scoreforskydning målt i sekunder inde i videoen; delen, der begynder dér, skal kunne rummes i videoen, så Start Offset plus Duration ikke kan overstige Video Duration. |
| `duration` |  | number \| null | no |  | 1 – 600 | Valgfri scorevarighed i sekunder; standarden None fortsætter scoringen gennem den resterende video. Uanset om en varighed angives eller udelades, begynder scoringen ved Start Offset, når den er angivet, ellers i begyndelsen. |

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-music?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-music?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-music", 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-music",
      "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.
