# Seedance 2.5 US Image to Video API

> Anima una imagen fija para crear un clip con audio generado, fotograma final opcional y salida de 480p a 1080p

Recibe un fotograma inicial en `image_url` y lo anima mediante un prompt de texto opcional que describe el movimiento. Proporcionar `end_image_url` hace que el clip transicione hacia un fotograma final. La resolución puede ser 480p, 720p o 1080p, y `duration` se establece en auto o en un número de segundos. La generación de audio, incluido el habla sincronizada con los labios, está activada de forma predeterminada, y `codec` y `bitrate_mode` controlan la codificación.

- 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`

## 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 |  |  | Instrucciones de movimiento y acción del video proporcionadas como prompt de texto. |
| `image_url` | `image` | string (image URL) | yes |  |  | URL de la imagen inicial que se animará. Los formatos aceptados son JPEG, PNG y WebP; el límite de tamaño es 30 MB. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL que apunta a una imagen JPEG, PNG o WebP de no más de 30 MB que define el fotograma final del video. Proporcionar esta imagen la convierte en el destino de la transición del video generado, que comienza con la imagen inicial. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p`, `1080p` | Resolución de salida: 480p prioriza la velocidad, 720p ofrece equilibrio y 1080p proporciona alta calidad. |
| `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` | Selección de duración del video: `auto` delega la elección al modelo mediante el prompt, mientras que una duración explícita debe ser de 4 a 30 segundos. |
| `aspect_ratio` |  | string | no | `auto` |  | Configuración de la relación de aspecto del video; la generación de imagen a video requiere el valor "auto". |
| `generate_audio` |  | boolean | no | `true` |  | Activa esta opción para acompañar el video con audio sincronizado. El audio generado incluye habla sincronizada con los movimientos de los labios, ambiente y efectos de sonido. |
| `bitrate_mode` |  | enum (string) | no | `standard` | `standard`, `high` | Elige la tasa de bits de codificación de salida: 'standard' conserva el valor predeterminado, mientras que 'high' solicita al modelo mejorar la calidad de codificación a costa de un archivo más grande. |
| `codec` |  | enum (string) | no | `auto` | `auto`, `H264`, `H265` | Selección del códec de video: `auto` mantiene sin cambios el comportamiento predeterminado del códec, `H264` selecciona H.264 y `H265` selecciona H.265. |
| `end_user_id` |  | string \| null | no |  |  | Identificador único asignado al usuario final. |

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.
