# Sam Audio · Visual Separate API

> Jifred ħoss mill-binarju awdjo ta’ vidjo, iggwidat minn vidjo b’maskra fakultattiv u prompt tat-test

Jieħu `video_url` u joħroġ ħoss fil-mira mill-awdjo tiegħu. `mask_video_url` fakultattiv jimmarka l-oġġett fil-mira (iswed għall-mira, abjad għall-isfond), u `prompt` jista' jżid indikazzjoni testwali. Jistgħu jiġu kklassifikati sa 4 `reranking_candidates`, u awdjo twil jinqasam f'biċċiet. L-output għandu awdjo `target` u `residual` f'wav jew mp3.

- Model id: `sam-audio/visual-separate`
- Made by: Meta
- Category: Video to Audio
- Output: json
- Price per 30 seconds of your input video: from $0.05 / 30 seconds of input video (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.com/v1/run/sam-audio/visual-separate`
- Quote: `POST https://api.doitong.com/v1/quote/sam-audio/visual-separate`
- Docs page: https://doitong.com/mt/developers/models/sam-audio/visual-separate

## Pricing

Price: **from $0.05 / 30 seconds of input video** (the lowest tier; the quote prices your exact input). Price per 30 seconds 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 $0.05 = 50 API credits (1 × 30 s input video × $0.05).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/sam-audio/visual-separate` 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 tal-fajl tal-vidjo għall-ipproċessar, f'formati bħal MP4 jew MOV. |
| `mask_video_url` |  | string (video URL) \| null | no |  |  | URL tal-vidjo tal-maskra li juża kodifikazzjoni binarja fejn l-oġġett immirat jidher iswed fuq sfond abjad. |
| `prompt` |  | string | no | `` |  | Deskrizzjoni bil-lingwa naturali tal-ħoss immirat biex tgħin fis-separazzjoni. |
| `reranking_candidates` |  | integer | no | `1` | 1 – 4 | Għadd ta' kandidati ġġenerati għall-klassifikazzjoni. |
| `acceleration` |  | enum (string) | no | `balanced` | `fast`, `balanced`, `quality` | Livell ta’ aċċelerazzjoni applikat għall-ipproċessar. |
| `max_chunk_duration` |  | number | no | `60` | 10 – 60 | Limitu tal-awdjo għal kull pass, imkejjel f'sekondi, li lil hinn minnu l-ipproċessar juża biċċiet li jikkoinċidu u jitħalltu flimkien. |
| `chunk_overlap` |  | number | no | `5` | 0 – 30 | Tul tal-koinċidenza bejn il-biċċiet, imkejjel f'sekondi, użat għat-taħlit crossfade. |
| `output_format` |  | enum (string) | no | `wav` | `wav`, `mp3` | Format għall-awdjo ġġenerat. |

File parameters (`video`, `mask_video_url`) 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.com/v1/run/sam-audio/visual-separate?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.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/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/sam-audio/visual-separate?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.com/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/sam-audio/visual-separate", 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.com/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": "sam-audio/visual-separate",
      "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.
