# Seedance 2.0 US Image to Video API

> Seedance 2.0 ya picha-hadi-video inayofikia 4k, ikiwa na fremu za mwanzo na mwisho na klipu za sekunde 4 hadi 15

Huamsha picha ya mwanzo (`image_url`) kwa kidokezo cha mwendo kinachohitajika na inaweza kumalizia kwenye `end_image_url`. Mwonekano ni 480p, 720p, 1080p au 4k, na muda ni auto au sekunde 4 hadi 15. Uwiano wa picha unaweza kukadiriwa kutoka kwenye picha au kuchaguliwa kutoka 21:9 hadi 9:16. Sauti huzalishwa kwa chaguomsingi, na `bitrate_mode` inaweza kuwekwa kuwa 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 |  |  | Maelekezo ya miondoko na vitendo vya video yanayotolewa kama kidokezo cha maandishi. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL ya picha ya mwanzo itakayopewa uhuishaji. Miundo inayokubalika ni JPEG, PNG, WebP; kikomo cha ukubwa ni 30 MB. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL inayoelekeza kwenye picha ya JPEG, PNG, au WebP isiyozidi 30 MB inayofafanua fremu ya mwisho ya video. Kutoa picha hii huifanya kuwa mwisho wa mpito wa video iliyozalishwa, ukianza na picha ya mwanzo. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p`, `4k` | Mwonekano wa tokeo: 480p hupendelea kasi, 720p hutoa uwiano, 1080p hutoa ubora wa juu, na 4k hutoa ubora wa juu zaidi. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15` | Uteuzi wa urefu wa video: `auto` hukabidhi chaguo kwa modeli kwa kutumia kidokezo, huku muda ulioainishwa lazima uwe kati ya sekunde 4 hadi 15. |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Uwiano wa picha wa tokeo: 16:9 hutoa mlalo, 9:16 hutoa picha wima, 1:1 hutoa mraba, na 21:9 hutoa mwonekano mpana wa sinema. Chagua `auto` ili kupata uwiano kutoka kwa picha ya ingizo. |
| `generate_audio` |  | boolean | no | `true` |  | Washa hii ili video iambatane na sauti iliyosawazishwa. Sauti iliyozalishwa inajumuisha usemi unaolingana na miondoko ya midomo, mandhari ya mazingira na athari za sauti. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Chagua kiwango cha biti cha usimbaji wa tokeo: 'standard' huhifadhi chaguo chaguomsingi, ilhali 'high' huiomba modeli kuboresha ubora wa usimbaji kwa gharama ya faili kubwa zaidi. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Uteuzi wa kodeki ya video: `auto` huacha tabia ya kodeki chaguomsingi bila kubadilika, `H264` huchagua H.264, na `H265` huchagua H.265. |
| `end_user_id` |  | string \| null | no |  |  | Kitambulisho cha kipekee alichopewa mtumiaji wa mwisho. |

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

### Python

```python
import os

headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {

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.
