# Seedance 2.0 Mini API

> Mini Seedance 2.0-videogeneratie gestuurd door maximaal 9 afbeeldingen, 3 video's en 3 audioverwijzingen

Genereert video vanuit een prompt plus referentiemedia: maximaal 9 `image_urls`, 3 `video_urls` en 3 `audio_urls`, in de prompt aangeduid als @Image1, @Video1, @Audio1 enzovoort. De uitvoer is 480p of 720p, auto of 4 tot 15 seconden, met beeldverhoudingen van 21:9 tot 9:16. Gesynchroniseerde audio wordt standaard gegenereerd.

- 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 |  |  | Tekstprompt die de videogeneratie aanstuurt. |
| `image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Afbeeldingsreferenties voor videogeleiding, beperkt tot 9 afbeeldingen en onderworpen aan een maximum van 12 bestanden voor alle modaliteiten samen. Elke afbeelding mag maximaal 30 MB groot zijn en moet JPEG, PNG of WebP gebruiken. Gebruik @Image1, @Image2 en volgende genummerde labels om deze referenties in de prompt te identificeren. |
| `video_urls` | `videos` | array of video URL | no |  | ≤ 3 items | Videoreferenties voor generatie, aangeleverd als MP4- of MOV-bestanden en in de prompt geïdentificeerd met @Video1, @Video2 en volgende genummerde labels. Elk bestand moet een resolutie hebben van ongeveer 480p (640x640) tot ongeveer 720p (834x1112). De set is beperkt tot 3 video's van samen minder dan 50 MB, met een totale duur van 2 tot 15 seconden. |
| `audio_urls` | `audios` | array of audio URL | no |  | ≤ 3 items | Audioreferenties voor videogeleiding vereisen ten minste één begeleidende afbeeldings- of videoreferentie. Lever MP3- of WAV-bestanden aan van maximaal 15 MB per stuk, met maximaal 3 bestanden en een totale duur van maximaal 15 seconden. Identificeer ze in de prompt met @Audio1, @Audio2 en volgende genummerde labels. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Uitvoerresolutie: 480p geeft prioriteit aan generatiesnelheid, terwijl 720p een evenwichtige keuze biedt. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Selectie van videolengte: `auto` laat de keuze op basis van de prompt aan het model over, terwijl een expliciete duur tussen 4 en 15 seconden moet liggen. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Beeldverhouding van de uitvoer: 16:9 geeft liggend, 9:16 geeft staand/verticaal, 1:1 geeft vierkant en 21:9 geeft cinematografisch ultrabreed. Selecteer `auto` om het model de verhouding te laten kiezen. |
| `generate_audio` |  | boolean | no | `true` |  | Schakel dit in om de video van gesynchroniseerde audio te voorzien. Gegenereerde audio bevat spraak die op lipbewegingen is afgestemd, omgevingsgeluid en geluidseffecten. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Selectie van videocodec: `auto` laat het standaardcodecgedrag ongewijzigd, `H264` selecteert H.264 en `H265` selecteert H.265. |
| `end_user_id` |  | string \| null | no |  |  | Unieke identificatie die aan de eindgebruiker is toegewezen. |

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.
