# Seedream 5.0 Pro Edit API

> Seedream 5.0 Proによる複数画像編集。最大10枚の参照画像を1枚の2K画像に合成。

Seedream 5.0 Proに最大10枚の参照画像（商品、ロゴ、人物、場所）を渡し、合成または変更方法を記述します。素材や文字を忠実に維持します。出力は1〜4メガピクセルで、1リクエストあたり最大6枚です。

- Model id: `bytedance/seedream/v5/pro/edit`
- Made by: ByteDance
- Category: Image Editing
- Output: image
- Price per run: from $0.0675 / run of output image (cheapest run $0.068 (68 API credits))
- Run: `POST https://api.doitong.com/v1/run/bytedance/seedream/v5/pro/edit`
- Quote: `POST https://api.doitong.com/v1/quote/bytedance/seedream/v5/pro/edit`
- Docs page: https://doitong.com/ja/developers/models/bytedance/seedream/v5/pro/edit

## Pricing

Price: **from $0.0675 / run of output image** (the lowest tier; the quote prices your exact input). Price per run: 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 $0.14 = 140 API credits (1 run × $0.1395).

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/bytedance/seedream/v5/pro/edit` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | 画像を編集するためのテキスト指示。 |
| `image_size` |  | object {width, height} \| enum (string) | no | `auto_2K` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9`, `auto_1K`, `auto_2K` | 出力画像の寸法。総ピクセル数は1024x1024–2048x2048、アスペクト比は1/16–16の範囲内である必要があります。 |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 6 | プロンプトを使用して独立したモデル生成を実行する回数。 |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | 出力画像のファイル形式。 |
| `enhance_prompt_mode` |  | enum (string) | no | `standard` | `standard`, `fast` | プロンプト最適化設定。画像品質を優先するには`standard`、生成時間を短くするには`fast`を選択します。 |
| `image_urls` | `images` | array of image URL | yes |  |  | 参照画像URL。指定リストが対応上限の10画像を超える場合、最後の10項目だけが処理されます。 |

File parameters (`images`) 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
{
  "prompt": "Place the sneaker from image 1 on the desk of the office from image 2, natural lighting",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
    "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
  ]
}
```

A fuller example:

```json
{
  "prompt": "Place the sneaker from image 1 on the desk of the office from image 2, natural lighting",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
    "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
  ]
}
```

## 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/bytedance/seedream/v5/pro/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Place the sneaker from image 1 on the desk of the office from image 2, natural lighting",
    "images": [
      "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
      "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
    ]
  }'

# 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 = {

  "Content-Type": "application/json",
};

    ]
  }),
});
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 = {
    "prompt": "Place the sneaker from image 1 on the desk of the office from image 2, natural lighting",
    "images": [
        "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
        "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png",
    ],
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/bytedance/seedream/v5/pro/edit", 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": "bytedance/seedream/v5/pro/edit",
      "input": {
        "prompt": "Place the sneaker from image 1 on the desk of the office from image 2, natural lighting",
        "images": [
          "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
          "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
        ]
      },
      "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.
