# Seedance 2.0 Reference to Video API

> Атымен көрсетілген ең көбі 9 суреттен, 3 бейнеден және 3 аудиоклиптен дыбысы бар 4–15 секундтық клип жасайды.

ByteDance компаниясының бірнеше сілтемені пайдаланатын бейне моделі: кейіпкерлерді, өнімдерді, орындарды, қозғалыс немесе камера сілтемесін және дауыс не музыка клипін жүктеп, оларды промптта @Image1, @Video1, @Audio1 және тағы сол сияқты көрсетуге болады. Ол кадрлар арасындағы нысандардың сәйкестігін сақтап, дыбысты бейнемен синхронды түрде жасайды. Кемінде бір сурет немесе бейне сілтемесі қажет, ал барлық сілтемелер бірге 12 файлдан аспауы керек. Нәтиже 480p-ден 4K-ға дейін.

## 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):

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/reference-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 |

Әрқайсысы 15 MB-тан аспайтын MP3 немесе WAV файл болуы керек; ең көбі 3 файл, жиынтық ұзақтығы 15 секунд. Нұсқауда оларды @Audio1, @Audio2 және кейінгі нөмірленген белгілермен көрсетіңіз. |

## 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/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \

    ],
    "resolution": "720p",
    "duration": 5
  }'

# 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"

### 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/reference-to-video",
      "input": {
        "prompt": "@Image1 The banana manager walks through the office and high-fives the carrot, upbeat comedy tone",
        "images": [
          "https://content.doitong.com/images/gp/image_20260610003801_541d9719_316882.png"
        ],
        "resolution": "720p",
        "duration": 5
      },
      "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.
