# Seedream 5.0 Pro Edit API

> Multi-image editing with Seedream 5.0 Pro, combining up to ten references into one 2K picture.

Give Seedream 5.0 Pro up to ten reference images (products, logos, people, places) and describe how to combine or change them; it keeps materials and lettering faithful. Output between 1 and 4 megapixels, up to six images per request.

- 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/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 |  |  | Text instructions for editing the image. |
| `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` | Output image dimensions, requiring a total pixel count within 1024x1024–2048x2048 and an aspect ratio within 1/16–16. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 6 | Count of independent model generation runs using the prompt. |
| `output_format` |  | enum (string) | no | `jpeg` | `jpeg`, `png` | File format for the output image. |
| `enhance_prompt_mode` |  | enum (string) | no | `standard` | `standard`, `fast` | Prompt optimization setting: choose `standard` to favor image quality or `fast` for shorter generation time. |
| `image_urls` | `images` | array of image URL | yes |  |  | Reference image URLs, with processing restricted to the final 10 entries whenever the submitted list exceeds the supported maximum of 10 images. |

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

    ]

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 });

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"

payload = {
    "prompt": "Place the sneaker from image 1 on the desk of the office from image 2, natural lighting",

# 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()

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):

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.
