# Pixelcut Video Background Removal API

> 動画から背景を除去し、透明または単色背景で多様な形式に書き出し

`video_url`の動画からフレーム単位で背景を除去します。`background`はtransparent、black、white、green、blue、magenta、または`background_color`を使ったcustomから選択できます。`output_format`はwebm、mp4、mov、mkv、gifの各バリアントに対応し、透明背景の場合のデフォルトはwebm_vp9です。

- Model id: `pixelcut/video-background-removal`
- Made by: Pixelcut
- Category: Background Removal
- Output: video
- Price per 30 frames of your input video: $0.022 / 30 frames of input video (cheapest run $0.022 (22 API credits))
- Run: `POST https://api.doitong.com/v1/run/pixelcut/video-background-removal`
- Quote: `POST https://api.doitong.com/v1/quote/pixelcut/video-background-removal`
- Docs page: https://doitong.com/ja/developers/models/pixelcut/video-background-removal

## Pricing

Price: **$0.022 / 30 frames of input video**. Price per 30 frames 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 $0.22 = 220 API credits (10 × 30 frames input video × $0.022).

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/pixelcut/video-background-removal` 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 |  |  | 入力動画を指すURL。 |
| `background` |  | enum (string) | no | `transparent` | `transparent`, `black`, `white`, `green`, `blue`, `magenta`, `custom` | 出力の背景。'transparent'、プリセットの色名、またはbackground_colorピッカーで選択した色に対する'custom'。 |
| `background_color` |  | object {r, g, b} | no |  |  | カスタム背景の単色。背景の選択が'custom'の場合のみ適用されます。 |
| `background_color.r` |  | integer | no | `0` | 0 – 255 |  |
| `background_color.g` |  | integer | no | `0` | 0 – 255 |  |
| `background_color.b` |  | integer | no | `0` | 0 – 255 |  |
| `output_format` |  | enum (string) \| null | no |  | `webm_vp9`, `mp4_h264`, `mp4_h265`, `mov_proresks`, `mov_h265`, `mkv_h264`, `mkv_h265`, `mkv_vp9`, `gif` | 出力動画形式の上書き。明示的に選択しない場合は自動検出が適用され、透明性にはデフォルトでwebm_vp9が使用されます。 |

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.com/v1/run/pixelcut/video-background-removal?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/pixelcut/video-background-removal?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/pixelcut/video-background-removal", 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": "pixelcut/video-background-removal",
      "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.
