# Seedance 2.0 Mini API

> Mini Seedance 2.0-myndbandagerð með allt að 9 myndum, 3 myndböndum og 3 hljóðviðmiðum sem leiðbeiningu

Býr til myndband úr prompti ásamt viðmiðunarmiðlum: allt að 9 `image_urls`, 3 `video_urls` og 3 `audio_urls`, sem vísað er í promptinu sem @Image1, @Video1, @Audio1 og svo framvegis. Úttak er 480p eða 720p, auto eða 4 til 15 sekúndur, með stærðarhlutföllum frá 21:9 til 9:16. Samstillt hljóð er sjálfgefið búið til.

## 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 |  |  | Textakvaðning sem stýrir efnisgerð myndbands. |
| `image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Myndtilvísanir fyrir leiðsögn myndbands, takmarkaðar við 9 myndir og háðar hámarki 12 skráa yfir allar miðlategundir. Hver mynd má mest vera 30 MB og verður að nota JPEG, PNG eða WebP. Notaðu @Image1, @Image2 og síðari númeruð merki til að auðkenna tilvísanirnar í kvaðningunni. |
| `video_urls` | `videos` | array of video URL | no |  | ≤ 3 items | Myndbandstilvísanir fyrir efnisgerð, gefnar upp sem MP4- eða MOV-skrár og auðkenndar í kvaðningunni með @Video1, @Video2 og síðari númeruðum merkjum. Hver þarf að hafa upplausn frá um það bil 480p (640x640) upp í um það bil 720p (834x1112). Mengi þeirra er takmarkað við 3 myndbönd sem eru samtals innan við 50 MB, með samanlagða lengd frá 2 til 15 sekúndum. |
| `audio_urls` | `audios` | array of audio URL | no |  | ≤ 3 items | Hljóðtilvísanir fyrir leiðsögn myndbands krefjast að minnsta kosti einnar meðfylgjandi mynda- eða myndbandstilvísunar. Gefðu upp MP3- eða WAV-skrár sem eru mest 15 MB hver, að hámarki 3 skrár og með samanlagða lengd að hámarki 15 sekúndur. Auðkenndu þær í kvaðningunni með @Audio1, @Audio2 og síðari númeruðum merkjum. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Úttaksupplausn: 480p leggur áherslu á hraða efnisgerðar en 720p býður upp á jafnvægi. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Val á lengd myndbands: `auto` felur líkaninu valið með kvaðningunni, en ákveðin lengd verður að vera frá 4 til 15 sekúndur. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Hlutfall úttaks: 16:9 gefur landslag, 9:16 andlitsmynd/lóðrétt, 1:1 ferning og 21:9 kvikmyndalegt ofurbreitt snið. Veldu `auto` til að láta líkanið velja hlutfallið. |
| `generate_audio` |  | boolean | no | `true` |  | Virkjaðu þetta til að fylgja myndbandinu eftir með samstilltu hljóði. Myndað hljóð inniheldur tal sem passar við varahreyfingar, umhverfishljóð og hljóðbrellur. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Val á myndbandskóðalykli: `auto` breytir sjálfgefinni hegðun ekki, `H264` velur H.264 og `H265` velur H.265. |
| `end_user_id` |  | string \| null | no |  |  | Einstakt auðkenni sem úthlutað er lokanotanda. |

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.
