# Seedance 2.0 Mini API

> Mini Seedance 2.0 video pagbuo na ginagabayan ng hanggang 9 na larawan, 3 video at 3 audio reference

Gumagawa ng video mula sa prompt at reference media: hanggang 9 `image_urls`, 3 `video_urls` at 3 `audio_urls`, na binabanggit sa prompt bilang @Image1, @Video1, @Audio1 at iba pa. Ang output ay 480p o 720p, auto o 4 hanggang 15 segundo, na may aspect ratio mula 21:9 hanggang 9:16. Bilang default, gumagawa ito ng synchronized audio.

- Model id: `bytedance/seedance-2.0/mini/reference-to-video`

- 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 |  |  | Text prompt na gumagabay sa pagbuo ng video. |
| `image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Mga larawan reference para sa video guidance, limitado sa 9 na larawan at napapailalim sa maximum na 12 file sa lahat ng modality. Hindi maaaring lumampas sa 30 MB ang bawat larawan at dapat ay JPEG, PNG, o WebP. Gamitin ang @Image1, @Image2, at mga kasunod na numerong label upang tukuyin ang mga reference na ito sa prompt. |
| `video_urls` | `videos` | array of video URL | no |  | ≤ 3 items | Mga video reference para sa pagbuo, na ibinibigay bilang MP4 o MOV file at tinutukoy sa prompt gamit ang @Video1, @Video2, at mga kasunod na numerong label. Dapat ay may resolution na humigit-kumulang 480p (640x640) hanggang humigit-kumulang 720p (834x1112) ang bawat isa. Limitado ang set sa 3 video na may kabuuang laki na mas mababa sa 50 MB, at kabuuang tagal na 2 hanggang 15 segundo. |
| `audio_urls` | `audios` | array of audio URL | no |  | ≤ 3 items | Ang mga audio reference para sa video guidance ay nangangailangan ng kahit isang kasamang larawan o video reference. Magbigay ng MP3 o WAV file na hanggang 15 MB bawat isa, na hindi lalampas sa 3 file at may pinagsamang tagal na hanggang 15 segundo. Tukuyin ang mga ito sa prompt gamit ang @Audio1, @Audio2, at mga kasunod na numerong label. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Output resolution: inuuna ng 480p ang bilis ng pagbuo, habang nag-aalok ang 720p ng balanseng pagpipilian. |
| `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 ang modelo ang pumili ng ratio. |
| `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. |
| `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. |
| `end_user_id` |  | string \| null | no |  |  | Natatanging identifier na itinalaga sa end user. |

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.
