# Seedance 2.5 US Image to Video API

> Ina-animate ang still larawan bilang clip na may nabuong audio, optional na end frame, at 480p hanggang 1080p na output

Tumatanggap ng panimulang frame sa `image_url` at ina-animate ito gamit ang opsyonal na teksto prompt na naglalarawan ng galaw. Kapag ibinigay ang `end_image_url`, lilipat ang clip patungo sa huling frame. Maaaring 480p, 720p o 1080p ang resolution, at ang `duration` ay auto o bilang ng segundo. Naka-on bilang default ang pagbuo ng audio, kabilang ang speech na may lip sync, at kinokontrol ng `codec` at `bitrate_mode` ang encode.

- Model id: `bytedance/seedance-2.5/us/image-to-video`
- Made by: ByteDance
- Category: Image to Video
- Output: video
- Charged by usage (up to $6.944 per run; the rest of the hold is refunded): $0.0107 / 1000 tokens (cheapest run $0.416 (416 API credits))
- Run: `POST https://api.doitong.ru/v1/run/bytedance/seedance-2.5/us/image-to-video`

- Docs page: https://doitong.com/fil/developers/models/bytedance/seedance-2.5/us/image-to-video

## Pricing

Price: **$0.0107 / 1000 tokens**. Charged by actual usage at $0.0107 / 1000 tokens: up to $6.944 per run (the quote gives the maximum for your input), the rest is refunded automatically after the run.

The full example input below holds up to $6.944 = 6944 API credits (up to 648.9 × 1000 tokens × $0.0107) when it starts.

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). This model is charged by usage: `POST https://api.doitong.ru/v1/quote/bytedance/seedance-2.5/us/image-to-video` with the same JSON body returns the most the run can cost for that input (`credits`, debited when the run starts); after the run you pay the usage the model reports and the rest is refunded automatically. An input whose maximum would exceed the per-run limit is refused with 422. 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 \| null | no |  |  | Mga instruction para sa galaw at aksyon ng video na ibinibigay bilang text prompt. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL ng paunang larawan na ia-animate. Tinatanggap na format ang JPEG, PNG, WebP; 30 MB ang limitasyon sa laki. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL na tumuturo sa JPEG, PNG, o WebP na larawang hindi lalampas sa 30 MB at tumutukoy sa final frame ng video. Kapag ibinigay ang larawang ito, ito ang magiging destinasyon ng transition ng nabuong video, na magsisimula sa panimulang larawan. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p` | Output resolution: inuuna ng 480p ang bilis, nag-aalok ang 720p ng balanse, at nagbibigay ang 1080p ng mataas na kalidad. |
| `duration` |  | enum (string) | no | `auto` | `auto`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15`, `16`, `17`, `18`, `19`, `20`, `21`, `22`, `23`, `24`, `25`, `26`, `27`, `28`, `29`, `30` | Pagpili ng haba ng video: ipinauubaya ng `auto` sa modelo ang pagpili gamit ang prompt, habang ang tahasang duration ay dapat mula 4 hanggang 30 segundo. |
| `aspect_ratio` |  | string | no | `auto` |  | Setting ng aspect ratio ng video; kinakailangan ng larawan-to-video pagbuo ang value na "auto". |
| `generate_audio` |  | boolean | no | `true` |  | I-enable ito upang samahan ang video ng naka-synchronize na audio. Kasama sa nabuong audio ang speech na tumutugma sa lip movements, environmental ambience, at sound effects. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Piliin ang bitrate ng output encoding: pinananatili ng 'standard' ang default, habang hinihiling ng 'high' sa modelo na pagandahin ang encoding quality kapalit ng mas malaking file. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Pagpili ng video codec: hindi binabago ng `auto` ang default na gawi ng codec, pinipili ng `H264` ang H.264, at pinipili ng `H265` ang H.265. |
| `end_user_id` |  | string \| null | no |  |  | Natatanging identifier na itinalaga sa end user. |

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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "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-2.5/us/image-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "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

```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-2.5/us/image-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
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 = {
    "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-2.5/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-2.5/us/image-to-video",
      "input": {
        "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.
