## Pricing

Price: **from $0.113 / second (4 s ≈ $0.452)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

The full example input below costs $0.565 = 565 API credits (5 s × 113 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/seedance-2.0/fast/image-to-video` 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 |  |  | تعليمات حركة الفيديو والفعل المقدمة كموجّه نصي. |
| `image_url` | `image` | string (image URL) | yes |  |  | عنوان URL للصورة الأولية التي ستُحرّك. التنسيقات المقبولة هي JPEG وPNG وWebP؛ وحد الحجم هو 30 MB. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | عنوان URL يشير إلى صورة JPEG أو PNG أو WebP لا يتجاوز حجمها 30 MB، وتحدد إطار الفيديو الأخير. يؤدي توفير هذه الصورة إلى جعلها وجهة الانتقال في الفيديو المُولّد، بدءًا من الصورة الابتدائية. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | دقة المخرج: تفضّل 480p سرعة التوليد، بينما توفّر 720p خيارًا متوازنًا. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | اختيار طول الفيديو: يفوّض `auto` الاختيار إلى النموذج باستخدام الموجّه، بينما يجب أن تتراوح المدة الصريحة من 4 إلى 15 ثانية. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | نسبة أبعاد المخرج: تمنح 16:9 تنسيقًا أفقيًا، و9:16 تنسيقًا عموديًا، و1:1 تنسيقًا مربعًا، و21:9 تنسيقًا سينمائيًا عريضًا جدًا. اختر `auto` لاشتقاق النسبة من الصورة المدخلة. |
| `generate_audio` |  | boolean | no | `true` |  | فعّل هذا لإرفاق صوت متزامن بالفيديو. يتضمن الصوت المُولّد كلامًا متوافقًا مع حركات الشفاه، وأجواءً محيطة، ومؤثرات صوتية. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | اختر معدل بت ترميز المخرج: يحتفظ 'standard' بالقيمة الافتراضية، بينما يطلب 'high' من النموذج تحسين جودة الترميز مقابل ملف أكبر. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | اختيار برنامج ترميز الفيديو: يترك `auto` سلوك برنامج الترميز الافتراضي دون تغيير، ويختار `H264` ‏H.264، ويختار `H265` ‏H.265. |

File parameters (`image`, `end_image`) 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": "The fox stops, looks up at the fireflies and leaps to catch one, playful mood",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "prompt": "The fox stops, looks up at the fireflies and leaps to catch one, playful mood",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "duration": 5,
  "resolution": "480p"
}
```

## 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/seedance-2.0/fast/image-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "The fox stops, looks up at the fireflies and leaps to catch one, playful mood",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 5,
    "resolution": "480p"
  }'

# 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/seedance-2.0/fast/image-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({

    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 5,
    "resolution": "480p"
  }),
});
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": "The fox stops, looks up at the fireflies and leaps to catch one, playful mood",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 5,
    "resolution": "480p",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/bytedance/seedance-2.0/fast/image-to-video", 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/seedance-2.0/fast/image-to-video",
      "input": {
        "prompt": "The fox stops, looks up at the fireflies and leaps to catch one, playful mood",
        "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "duration": 5,
        "resolution": "480p"
      },
      "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.
