# Seedance 2.0 Image to Video API

> शुरुआत की इमेज (और वैकल्पिक अंतिम इमेज) को ध्वनि वाले 4 से 15 सेकंड के दृश्य में बदलता है, अधिकतम 4K तक

Seedance 2.0 आपकी पहली फ़्रेम को समकालिक संवाद और ध्वनि प्रभावों वाले मल्टी-शॉट दृश्य में एनिमेट करता है और इमेज का रूप बनाए रखता है। क्लिप कहाँ समाप्त हो, इसे नियंत्रित करने के लिए अंतिम इमेज जोड़ें। 4 से 15 सेकंड या स्वचालित लंबाई, अनुकूली या निश्चित आस्पेक्ट रेशियो, 480p से 4K।

- Price: from $0.141 / second (4 s ≈ $0.564) (cheapest run $0.564 (564 API credits))
- Run: `POST https://api.doitong.ru/v1/run/bytedance/seedance-2.0/image-to-video`

## 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).

The full example input below costs $1.52 = 1520 API credits (5 s × 304 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/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 |  |  | टेक्स्ट प्रॉम्प्ट के रूप में दिए गए वीडियो गति और क्रिया निर्देश। |
| `image_url` | `image` | string (image URL) | yes |  |  | एनिमेट की जाने वाली शुरुआती इमेज का URL। स्वीकृत फ़ॉर्मैट JPEG, PNG, WebP हैं; आकार सीमा 30 MB है। |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | 30 MB से बड़ी न होने वाली JPEG, PNG या WebP इमेज की ओर संकेत करने वाला URL, जो वीडियो के अंतिम फ़्रेम को परिभाषित करता है। यह इमेज देने पर शुरुआती इमेज से शुरू होने वाले निर्मित वीडियो के ट्रांज़िशन का गंतव्य यही बनती है। |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p`, `4k` | आउटपुट रिज़ॉल्यूशन: 480p गति को प्राथमिकता देता है, 720p संतुलन देता है, 1080p उच्च गुणवत्ता देता है और 4k सर्वोच्च गुणवत्ता देता है। |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | वीडियो लंबाई चयन: `auto` प्रॉम्प्ट के आधार पर विकल्प मॉडल को सौंपता है, जबकि स्पष्ट अवधि 4 से 15 सेकंड के बीच होनी चाहिए। |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | आउटपुट आस्पेक्ट रेशियो: 16:9 लैंडस्केप, 9:16 पोर्ट्रेट/वर्टिकल, 1:1 वर्गाकार और 21:9 सिनेमैटिक अल्ट्रावाइड देता है। इनपुट इमेज से अनुपात निकालने के लिए `auto` चुनें। |
| `generate_audio` |  | boolean | no | `true` |  | वीडियो के साथ सिंक्रोनाइज़्ड ऑडियो जोड़ने के लिए इसे सक्षम करें। निर्मित ऑडियो में होंठों की गतिविधियों से मेल खाता भाषण, परिवेशी माहौल और ध्वनि प्रभाव शामिल होते हैं। |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | आउटपुट एन्कोडिंग बिटरेट चुनें: 'standard' डिफ़ॉल्ट बनाए रखता है, जबकि 'high' बड़ी फ़ाइल की कीमत पर एन्कोडिंग गुणवत्ता सुधारने के लिए मॉडल से कहता है। |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | वीडियो कोडेक चयन: `auto` डिफ़ॉल्ट कोडेक व्यवहार को अपरिवर्तित रखता है, `H264` H.264 चुनता है और `H265` H.265 चुनता है। |

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, gentle music",
  "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, gentle music",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
  "duration": 5,
  "resolution": "720p"
}
```

## 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/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, gentle music",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 5,
    "resolution": "720p"
  }'

# 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

const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

  }),
});
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") {

### 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, gentle music",
    "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
    "duration": 5,
    "resolution": "720p",
}

# 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/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":

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/image-to-video",
      "input": {
        "prompt": "The fox stops, looks up at the fireflies and leaps to catch one, playful mood, gentle music",
        "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
        "duration": 5,
        "resolution": "720p"
      },
      "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.
