# Seedance 2.0 US Image to Video API

> Seedance 2.0 attēla pārveide video līdz 4k ar sākuma un beigu kadriem un 4 līdz 15 sekunžu klipiem

Animē sākuma attēlu (`image_url`) pēc obligātas kustības uzvednes un var noslēgties ar `end_image_url`. Izšķirtspēja ir 480p, 720p, 1080p vai 4k, ilgums — auto vai 4 līdz 15 sekundes. Malu attiecību var noteikt pēc attēla vai izvēlēties no 21:9 līdz 9:16. Audio pēc noklusējuma tiek ģenerēts, bet `bitrate_mode` var iestatīt uz high.

## Pricing

Price: **from $0.141 / second (4 s ≈ $0.564)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 720p: $0.3034 (303.4 API credits) / second
- When `resolution` = 1080p: $0.682 (682 API credits) / second
- When `resolution` = 4k: $1.5552 (1555.2 API credits) / second

The full example input below costs $4.551 = 4551 API credits (15 s × 303.4 API credits).

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/us/image-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 |  |  | Video kustības un darbību instrukcijas, kas norādītas kā teksta uzvedne. |
| `image_url` | `image` | string (image URL) | yes |  |  | Sākotnējā animējamā attēla URL. Atbalstītie formāti ir JPEG, PNG, WebP; izmēra ierobežojums ir 30 MB. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL, kas norāda uz JPEG, PNG vai WebP attēlu, kura izmērs nepārsniedz 30 MB un kas nosaka video beigu kadru. Šī attēla norādīšana padara to par ģenerētās video pārejas galamērķi, sākot no sākuma attēla. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p`, `4k` | Izvades izšķirtspēja: 480p prioritizē ātrumu, 720p nodrošina līdzsvaru, 1080p — augstu kvalitāti, bet 4k — visaugstāko kvalitāti. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Video ilguma izvēle: `auto` ļauj modelim izvēlēties, izmantojot uzvedni, bet tieši norādītam ilgumam jābūt no 4 līdz 15 sekundēm. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Izvades malu attiecība: 16:9 nodrošina ainavas orientāciju, 9:16 — portreta/vertikālo, 1:1 — kvadrātveida, bet 21:9 — kinematogrāfisku īpaši plato. Izvēlieties `auto`, lai attiecību noteiktu pēc ievades attēla. |
| `generate_audio` |  | boolean | no | `true` |  | Iespējojiet šo opciju, lai video papildinātu ar sinhronizētu audio. Ģenerētais audio ietver runu, kas saskaņota ar lūpu kustībām, vides atmosfēru un skaņas efektus. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Izvēlieties izvades kodējuma bitreitu: 'standard' saglabā noklusējumu, bet 'high' pieprasa uzlabot kodējuma kvalitāti, palielinot faila izmēru. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Video kodeka izvēle: `auto` nemaina noklusējuma kodeka darbību, `H264` izvēlas H.264, bet `H265` — H.265. |
| `end_user_id` |  | string \| null | no |  |  | Gala lietotājam piešķirts unikāls identifikators. |

File parameters (`image`, `end_image`) 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",
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## 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/us/image-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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# 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

  "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/us/image-to-video?wait=20", {

  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();

### 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",
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# 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/us/image-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/us/image-to-video",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "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.
