# Seedance 2.0 Image to Video API

> Binibigyang-buhay ang start larawan (at optional na end larawan) bilang 4 hanggang 15 segundong scene na may tunog, hanggang 4K

Ina-animate ng Seedance 2.0 ang iyong first frame bilang multi-shot scene na may naka-sync na dialogue at sound effect, habang pinapanatili ang hitsura ng larawan. Magdagdag ng end larawan upang kontrolin kung saan matatapos ang clip. 4 hanggang 15 segundo o awtomatikong haba, adaptive o fixed na aspect ratio, 480p hanggang 4K.

- 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 |  |  | Mga instruction para sa galaw at aksyon ng video na ibinibigay bilang text prompt. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL ng paunang larawan na ia-animate. Tinatanggap na format ang JPEG, PNG, WebP; 30 MB ang limitasyon sa laki. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL na tumuturo sa JPEG, PNG, o WebP na larawang hindi lalampas sa 30 MB at tumutukoy sa final frame ng video. Kapag ibinigay ang larawang ito, ito ang magiging destinasyon ng transition ng nabuong video, na magsisimula sa panimulang larawan. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p`, `4k` | Output resolution: inuuna ng 480p ang bilis, nag-aalok ang 720p ng balanse, nagbibigay ang 1080p ng mataas na kalidad, at nagbibigay ang 4k ng pinakamataas na kalidad. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Pagpili ng haba ng video: ipinauubaya ng `auto` sa modelo ang pagpili gamit ang prompt, habang ang tahasang duration ay dapat mula 4 hanggang 15 segundo. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Output aspect ratio: nagbibigay ang 16:9 ng landscape, ang 9:16 ng portrait/vertical, ang 1:1 ng square, at ang 21:9 ng cinematic ultrawide. Piliin ang `auto` upang kunin ang ratio mula sa input larawan. |
| `generate_audio` |  | boolean | no | `true` |  | I-enable ito upang samahan ang video ng naka-synchronize na audio. Kasama sa nabuong audio ang speech na tumutugma sa lip movements, environmental ambience, at sound effects. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Piliin ang bitrate ng output encoding: pinananatili ng 'standard' ang default, habang hinihiling ng 'high' sa modelo na pagandahin ang encoding quality kapalit ng mas malaking file. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Pagpili ng video codec: hindi binabago ng `auto` ang default na gawi ng codec, pinipili ng `H264` ang H.264, at pinipili ng `H265` ang 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, 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

### 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.
