# Bytedance Seedream V4.5 Text To Image API

> 2K سے 4K سائز میں ٹیکسٹ ٹو امیج جنریشن، ہر ریکویسٹ میں اختیاری کثیر التصویر آؤٹ پٹ کے ساتھ

Seedream 4.5 کا صرف متنی تخلیق ویرینٹ، جس کے لیے ان پٹ تصویر درکار نہیں۔ `prompt` سیٹ کریں اور `image_size` پری سیٹ مثلاً landscape_16_9، auto_2K یا auto_4K منتخب کریں، یا حسبِ ضرورت ابعاد دیں۔ `num_images` اور `max_images` دونوں زیادہ سے زیادہ 6 کی اجازت دیتے ہیں، اور `seed` نتائج کو قابلِ تکرار بناتا ہے۔ جواب میں استعمال شدہ سیڈ شامل ہوتا ہے۔

- Model id: `bytedance/seedream/v4.5/text-to-image`
- Made by: ByteDance
- Category: Text to Image
- Output: image
- Price: $0.04 / image (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.ru/v1/run/bytedance/seedream/v4.5/text-to-image`
- Quote: `POST https://api.doitong.ru/v1/quote/bytedance/seedream/v4.5/text-to-image`
- Docs page: https://doitong.com/ur/developers/models/bytedance/seedream/v4.5/text-to-image

## Pricing

Price: **$0.04 / image**. Billed per generated image (`num_images` × `max_images`, default 1).

The full example input below costs $0.04 = 40 API credits (1 image × 40 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.ru/v1/quote/bytedance/seedream/v4.5/text-to-image` 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 تخلیق کرنے کی 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_2K`, `auto_4K` | تخلیق شدہ تصویر کا سائز دو میں سے کسی ایک شرط کو پورا کرے: کل pixel count 2560*1440 سے 4096*4096 تک، یا width اور height دونوں 1920–4096 کے اندر۔ |
| `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۔ |
| `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۔ |

## Example input

Required parameters only:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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.ru/v1/run/bytedance/seedream/v4.5/text-to-image?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"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/v4.5/text-to-image?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"
  }),
});
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.ru/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",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/bytedance/seedream/v4.5/text-to-image", 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.ru/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/v4.5/text-to-image",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
