# Seedance 2.0 Mini API

> Penjanaan video Mini Seedance 2.0 yang dipandu oleh sehingga 9 imej, 3 video dan 3 rujukan audio

Menjana video daripada prompt serta media rujukan: sehingga 9 `image_urls`, 3 `video_urls` dan 3 `audio_urls`, yang disebut dalam prompt sebagai @Image1, @Video1, @Audio1 dan seterusnya. Output ialah 480p atau 720p, auto atau 4 hingga 15 saat, dengan nisbah aspek dari 21:9 hingga 9:16. Audio disegerakkan dijana secara lalai.

- Model id: `bytedance/seedance-2.0/mini/reference-to-video`
- Made by: ByteDance
- Category: Reference to Video
- Output: video
- Price per 1000 tokens: $0.007 / 1000 tokens (cheapest run $0.007 (7 API credits))
- Run: `POST https://api.doitong.ru/v1/run/bytedance/seedance-2.0/mini/reference-to-video`

## Pricing

Price: **$0.007 / 1000 tokens**. Price per 1000 tokens: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $2.321 = 2321 API credits (331.5586 × 1000 tokens × $0.007 (720p)).

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/mini/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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Prompt teks yang membimbing penjanaan video. |
| `image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Rujukan imej untuk panduan video, dihadkan kepada 9 imej dan tertakluk kepada maksimum 12 fail merentas semua modaliti. Setiap imej boleh berukuran maksimum 30 MB dan mesti menggunakan JPEG, PNG atau WebP. Gunakan @Image1, @Image2 dan label bernombor seterusnya untuk mengenal pasti rujukan ini dalam prompt. |
| `video_urls` | `videos` | array of video URL | no |  | ≤ 3 items | Rujukan video untuk penjanaan, dibekalkan sebagai fail MP4 atau MOV dan dikenal pasti dalam prompt melalui @Video1, @Video2 dan label bernombor seterusnya. Setiap satu mesti mempunyai resolusi kira-kira 480p (640x640) hingga kira-kira 720p (834x1112). Set ini dihadkan kepada 3 video dengan jumlah kurang daripada 50 MB, dan tempoh keseluruhan antara 2 hingga 15 saat. |
| `audio_urls` | `audios` | array of audio URL | no |  | ≤ 3 items | Rujukan audio untuk panduan video memerlukan sekurang-kurangnya satu rujukan imej atau video yang disertakan. Bekalkan fail MP3 atau WAV maksimum 15 MB setiap satu, tidak lebih daripada 3 fail dan jumlah tempoh dihadkan kepada 15 saat. Kenal pastinya dalam prompt menggunakan @Audio1, @Audio2 dan label bernombor seterusnya. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Resolusi output: 480p mengutamakan kelajuan penjanaan, manakala 720p menawarkan pilihan seimbang. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Pemilihan panjang video: `auto` menyerahkan pilihan kepada model menggunakan prompt, manakala tempoh nyata mestilah antara 4 hingga 15 saat. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Nisbah aspek output: 16:9 menghasilkan landskap, 9:16 potret/menegak, 1:1 segi empat sama dan 21:9 ultralebar sinematik. Pilih `auto` untuk membenarkan model memilih nisbah. |
| `generate_audio` |  | boolean | no | `true` |  | Dayakan ini untuk mengiringi video dengan audio yang disegerakkan. Audio yang dijana merangkumi pertuturan yang dipadankan dengan pergerakan bibir, suasana persekitaran dan kesan bunyi. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Pemilihan codec video: `auto` mengekalkan tingkah laku codec lalai, `H264` memilih H.264 dan `H265` memilih H.265. |
| `end_user_id` |  | string \| null | no |  |  | Pengecam unik yang diberikan kepada pengguna akhir. |

File parameters (`images`, `videos`, `audios`) 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"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/mini/reference-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"
  }'

# 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/mini/reference-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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",
}

# 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/mini/reference-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/mini/reference-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
