# Bytedance Seedream V4 Edit API

> زیادہ سے زیادہ 10 ان پٹ تصاویر کی پرامپٹ پر مبنی ایڈیٹنگ، کثیر التصویر آؤٹ پٹ اور تیز یا معیاری پرامپٹ افزائش کے ساتھ

ٹیکسٹ پرامپٹ سے موجودہ تصاویر میں ترمیم کرتا ہے۔ `image_urls` زیادہ سے زیادہ 10 تصاویر قبول کرتا ہے؛ زیادہ تصاویر بھیجی جائیں تو صرف آخری 10 استعمال ہوتی ہیں۔ آؤٹ پٹ سائز square_hd، portrait_16_9، auto_2K یا auto_4K جیسے پری سیٹ یا حسبِ ضرورت چوڑائی اور اونچائی ہو سکتا ہے۔ متعدد نتائج کے لیے `num_images` اور `max_images` دونوں کی زیادہ سے زیادہ قدر 6 ہے، جبکہ `enhance_prompt_mode` standard اور fast کے درمیان انتخاب کرتا ہے۔

- Model id: `bytedance/seedream/v4/edit`
- Made by: ByteDance
- Category: Image Editing
- Output: image
- Price: $0.03 / image (cheapest run $0.03 (30 API credits))
- Run: `POST https://api.doitong.com/v1/run/bytedance/seedream/v4/edit`
- Quote: `POST https://api.doitong.com/v1/quote/bytedance/seedream/v4/edit`
- Docs page: https://doitong.com/ur/developers/models/bytedance/seedream/v4/edit

## Pricing

Price: **$0.03 / image**. Billed per generated image (`num_images` × `max_images`, default 1).

The full example input below costs $0.03 = 30 API credits (1 image × 30 API credits).

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/v4/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 |  |  | تصویر editing کے لیے متنی ہدایات۔ |
| `image_size` |  | object {width, height} \| enum (string) | no | `{"height":2048,"width":2048}` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9`, `auto`, `auto_2K`, `auto_4K` | تخلیق شدہ تصویر کی dimensions منتخب کریں۔ اگر area 921600 pixels سے کم ہو تو aspect ratio بدلے بغیر minimum پورا کرنے کے لیے انہیں متناسب طور پر بڑھایا جاتا ہے۔ |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 6 | پرامپٹ استعمال کرنے والی آزادانہ ماڈل تخلیق runs کی تعداد۔ |
| `max_images` |  | integer | no | `1` | 1 – 6 | `max_images` کے ذریعے ہر تخلیق کی تصویر ceiling مقرر کریں؛ one سے زیادہ values multi-image تخلیق فعال کرتی ہیں۔ `num_images` تخلیقات میں ہر ایک `max_images` تک تصاویر واپس کر سکتی ہے، اس لیے کل آؤٹ پٹ count `num_images` سے `max_images*num_images` تک ہو گا۔ ان پٹ اور آؤٹ پٹ ملا کر 15 سے زیادہ تصاویر استعمال نہیں کی جا سکتیں۔ |
| `seed` |  | integer \| null | no |  |  | تصویر تخلیق کے دوران randomness کو کنٹرول کرنے والا random seed۔ |
| `enable_safety_checker` |  | boolean | no | `true` |  | Safety-checking switch؛ off setting کے لیے account authorization ضروری ہے۔ authorization کے بغیر setting سے قطع نظر ہر درخواست check کی جاتی ہے؛ true checker فعال کرتا ہے۔ |
| `enhance_prompt_mode` |  | enum (string) | no | `standard` | `standard`, `fast` | quality/time trade-off کے مطابق پرامپٹ enhancement mode منتخب کریں: Fast کم وقت لیتا ہے مگر اوسط quality دیتا ہے؛ Standard زیادہ وقت لیتا ہے مگر بہتر quality دیتا ہے۔ |
| `image_urls` | `images` | array of image URL | yes |  |  | Editing تصویر URLs؛ فہرست طویل ہونے پر آخری 10 entries process کی جاتی ہیں، موجودہ ان پٹ limit 10 تصاویر ہے۔ |

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": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image_urls": [
    "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  ]
}
```

## 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/v4/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "image_urls": [
      "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    ]
  }'

# 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/bytedance/seedream/v4/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "image_urls": [
      "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
    ]
  }),
});
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": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "image_urls": [
        "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    ],
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/bytedance/seedream/v4/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/v4/edit",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_urls": [
          "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
        ]
      },
      "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.
