# Sonilo V1.1 API

> Ka waihanga puoro mō tētahi ataata, ka whakahoki oro anake, me te kōwhiringa wāhanga

Ka tātari i te ataata kei `video_url`, ā, ka whakaputa waiata taurite hei ara ororongo motuhake. Ka taea e tētahi `prompt` te ārahi i te kāhua, me `prompt_influence` mai i te 0 ki te 1; ki te kore, ka hangaia he tohutohu mai i te ataata. Ka aromātai a `start_offset` me `duration` (tae atu ki te 600 hēkona) i tētahi wāhanga anake, ā, ka hoatu e `num_samples` ngā ara 1 ki te 3.

- Output: audio
- Price per second of your output audio: $0.009 / second of output audio (cheapest run $0.009 (9 API credits))
- Run: `POST https://api.doitong.ru/v1/run/sonilo/v1.1/video-to-music`

## 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-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 |  |  | URL HTTP, HTTPS rānei e wātea ana ki te katoa mō te ataata hei whiwhi puoro. |
| `num_samples` |  | integer | no | `1` | 1 – 3 | Te maha o ngā ara puoro motuhake hei whakaputa mō te ataata. |
| `prompt` |  | string \| null | no |  |  | He aratohu āhua-puoro hei whakakapi ā-ringa i te tohutohu i puta aunoa mai i te ataata. |
| `prompt_influence` |  | number | no | `0.5` | 0 – 1 | Te kaha o te whai i te tohutohu; whakanuia kia pātata ake ki te tohutohu ā-tuhi. |
| `start_offset` |  | number \| null | no |  | 0 – 600 | He nuku tīmata kōwhiringa mō te tohu, ka inehia ki te hēkona ki roto i te ataata; me uru te wāhanga ka tīmata ki reira ki roto i te ataata, nō reira kāore e taea e Start Offset me Duration te hipa i Video Duration. |
| `duration` |  | number \| null | no |  | 1 – 600 | Te roa kōwhiringa o te wāhanga ki te hēkona, ko None te taunoa hei tohu tae noa ki te mutunga o te ataata. Ka tīmata te tohu ki Start Offset mēnā ka tukuna, ki te tīmatanga kē, nō reira ka kapi e None te wāhanga e toe ana, te ataata katoa rānei. Mā te roanga kua tukuna e whakawhāiti te tohu ki taua roanga mai i taua wāhi tīmata. |

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-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-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-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-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.
