# Seedance 2.0 Fast Image to Video API

> Seedance 2.0 image-to-video yang lebih cepat dan murah, pada 480p atau 720p dengan suara.

Tier cepat Seedance 2.0 menganimasikan gambar awal, secara opsional menuju gambar akhir, dengan audio tersinkronisasi, pada 480p atau 720p. Durasi 4 hingga 15 detik atau otomatis. Gunakan untuk mencoba ide gerakan dengan biaya rendah sebelum render berkualitas penuh.

- Model id: `bytedance/seedance-2.0/fast/image-to-video`

- Category: Image to Video
- Output: video
- Price: from $0.113 / second (4 s ≈ $0.452) (cheapest run $0.452 (452 API credits))
- Run: `POST https://api.doitong.ru/v1/run/bytedance/seedance-2.0/fast/image-to-video`

## 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 |  |  | Instruksi gerakan dan aksi video yang diberikan sebagai prompt teks. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL gambar awal yang akan dianimasikan. Format yang diterima adalah JPEG, PNG, WebP; batas ukurannya 30 MB. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL gambar JPEG, PNG, atau WebP berukuran maksimal 30 MB yang menentukan bingkai terakhir video. Gambar ini menjadi tujuan transisi video yang dihasilkan, dimulai dari gambar awal. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Resolusi output: 480p mengutamakan kecepatan pembuatan, sedangkan 720p menawarkan pilihan seimbang. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Pemilihan durasi video: `auto` menyerahkan pilihan kepada model menggunakan prompt, sedangkan durasi eksplisit harus berada dalam 4 hingga 15 detik. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Rasio aspek output: 16:9 menghasilkan lanskap, 9:16 potret/vertikal, 1:1 persegi, dan 21:9 ultrawide sinematik. Pilih `auto` untuk menentukan rasio dari gambar input. |
| `generate_audio` |  | boolean | no | `true` |  | Aktifkan ini untuk menyertakan audio tersinkronisasi pada video. Audio yang dihasilkan mencakup ucapan yang disesuaikan dengan gerakan bibir, suasana lingkungan, dan efek suara. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Pilih bitrate encoding output: 'standard' mempertahankan bawaan, sedangkan 'high' meminta model meningkatkan kualitas encoding dengan konsekuensi ukuran file lebih besar. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Pemilihan codec video: `auto` mempertahankan perilaku codec bawaan, `H264` memilih H.264, dan `H265` memilih 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,

    "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.
