# Seedance 2.0 Mini API

> Generowanie filmów Mini Seedance 2.0 sterowane maksymalnie 9 obrazami, 3 filmami i 3 referencjami audio

Generuje film na podstawie promptu i multimediów referencyjnych: maksymalnie 9 `image_urls`, 3 `video_urls` i 3 `audio_urls`, wskazywanych w promptcie jako @Image1, @Video1, @Audio1 itd. Wynik ma 480p lub 720p, długość auto albo od 4 do 15 sekund oraz proporcje od 21:9 do 9:16. Domyślnie generowane jest zsynchronizowane audio.

- 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 tekstowy kierujący generowaniem wideo. |
| `image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Odwołania do obrazów używane do sterowania wideo, ograniczone do 9 obrazów i podlegające limitowi 12 plików łącznie we wszystkich modalnościach. Każdy obraz może mieć maksymalnie 30 MB i musi być w formacie JPEG, PNG lub WebP. Użyj @Image1, @Image2 i kolejnych numerowanych etykiet, aby identyfikować te odwołania w promptcie. |
| `video_urls` | `videos` | array of video URL | no |  | ≤ 3 items | Odwołania do wideo do generowania, podane jako pliki MP4 lub MOV i identyfikowane w promptcie za pomocą @Video1, @Video2 i kolejnych numerowanych etykiet. Każde musi mieć rozdzielczość od około 480p (640x640) do około 720p (834x1112). Zestaw jest ograniczony do 3 wideo o łącznym rozmiarze poniżej 50 MB i łącznym czasie trwania od 2 do 15 sekund. |
| `audio_urls` | `audios` | array of audio URL | no |  | ≤ 3 items | Odwołania do audio do sterowania wideo wymagają co najmniej jednego towarzyszącego odwołania do obrazu lub wideo. Podaj pliki MP3 lub WAV o rozmiarze maksymalnie 15 MB każdy, nie więcej niż 3 pliki i łącznym czasie trwania ograniczonym do 15 sekund. Zidentyfikuj je w promptcie za pomocą @Audio1, @Audio2 i kolejnych numerowanych etykiet. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Rozdzielczość wyniku: 480p zapewnia szybkość generowania, a 720p stanowi zrównoważony wybór. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Wybór długości wideo: `auto` przekazuje wybór modelowi na podstawie promptu, natomiast jawny czas trwania musi wynosić od 4 do 15 sekund. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Proporcje obrazu wyniku: 16:9 oznacza orientację poziomą, 9:16 pionową, 1:1 kwadrat, a 21:9 kinowy format ultrapanoramiczny. Wybierz `auto`, aby model wybrał proporcje. |
| `generate_audio` |  | boolean | no | `true` |  | Włącz, aby dołączyć do wideo zsynchronizowane audio. Generowane audio zawiera mowę dopasowaną do ruchu ust, atmosferę otoczenia i efekty dźwiękowe. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Wybór kodeka wideo: `auto` pozostawia domyślne działanie kodeka bez zmian, `H264` wybiera H.264, a `H265` wybiera H.265. |
| `end_user_id` |  | string \| null | no |  |  | Unikalny identyfikator przypisany użytkownikowi końcowemu. |

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.
