# Seedance 2.0 US Image to Video API

> Seedance 2.0 image-to-video، 4k تک، ابتدائی و آخری فریم اور 4 سے 15 سیکنڈ کی کلپس کے ساتھ

لازمی حرکت کے پرامپٹ سے ابتدائی تصویر (`image_url`) میں اینیمیشن شامل کرتا ہے اور `end_image_url` پر ختم ہو سکتا ہے۔ ریزولوشنز 480p، 720p، 1080p یا 4k ہیں، اور مدت auto یا 4 سے 15 سیکنڈ ہے۔ نسبتِ ابعاد تصویر سے اخذ کی جا سکتی ہے یا 21:9 سے 9:16 تک منتخب کی جا سکتی ہے۔ آڈیو ڈیفالٹ طور پر تخلیق ہوتی ہے، اور `bitrate_mode` کو high پر سیٹ کیا جا سکتا ہے۔

## Pricing

Price: **from $0.141 / second (4 s ≈ $0.564)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 720p: $0.3034 (303.4 API credits) / second
- When `resolution` = 1080p: $0.682 (682 API credits) / second
- When `resolution` = 4k: $1.5552 (1555.2 API credits) / second

The full example input below costs $4.551 = 4551 API credits (15 s × 303.4 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/us/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 |  |  | ویڈیو کی حرکت اور action کی ہدایات بطور متنی پرامپٹ۔ |
| `image_url` | `image` | string (image URL) | yes |  |  | ابتدائی تصویر کا URL جسے متحرک کیا جائے گا۔ منظور شدہ فارمیٹس JPEG، PNG، WebP ہیں؛ سائز کی حد 30 MB ہے۔ |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | JPEG، PNG یا WebP تصویر کا URL، جو 30 MB سے بڑی نہ ہو اور ویڈیو کے آخری فریم کی وضاحت کرے۔ یہ تصویر فراہم کرنے سے تخلیق شدہ ویڈیو کی transition کا destination یہی بن جاتا ہے، جو starting تصویر سے شروع ہوتی ہے۔ |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p`, `4k` | آؤٹ پٹ ریزولوشن: 480p رفتار، 720p توازن، 1080p اعلیٰ معیار اور 4k سب سے اعلیٰ معیار فراہم کرتا ہے۔ |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | ویڈیو کی لمبائی: `auto` پرامپٹ کے ذریعے ماڈل کو انتخاب سونپتا ہے، جبکہ واضح دورانیہ 4 سے 15 سیکنڈ کے درمیان ہونا چاہیے۔ |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | آؤٹ پٹ aspect ratio: 16:9 landscape، 9:16 portrait/vertical، 1:1 square اور 21:9 cinematic ultrawide فراہم کرتا ہے۔ ان پٹ تصویر سے ratio اخذ کرنے کے لیے `auto` منتخب کریں۔ |
| `generate_audio` |  | boolean | no | `true` |  | ویڈیو کے ساتھ synchronized آڈیو شامل کرنے کے لیے اسے فعال کریں۔ تخلیق شدہ آڈیو میں lip movements سے ہم آہنگ speech، ماحولیاتی ambience اور sound effects شامل ہیں۔ |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | آؤٹ پٹ encoding bitrate منتخب کریں: 'standard' ڈیفالٹ برقرار رکھتا ہے، جبکہ 'high' بڑی فائل کے بدلے ماڈل سے encoding quality بہتر کرنے کو کہتا ہے۔ |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | ویڈیو codec کا انتخاب: `auto` ڈیفالٹ codec behavior برقرار رکھتا ہے، `H264` H.264 اور `H265` H.265 منتخب کرتا ہے۔ |
| `end_user_id` |  | string \| null | no |  |  | آخری صارف کو تفویض کردہ منفرد شناخت کنندہ۔ |

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": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image": "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_url": "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.ru/v1/run/bytedance/seedance-2.0/us/image-to-video?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_url": "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.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/us/image-to-video?wait=20", {
  method: "POST",
  headers,

    "image_url": "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.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",
    "image_url": "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/seedance-2.0/us/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/us/image-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_url": "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.
