# Wan 2.5 Image to Video API

> Wan 2.5 image-to-video mit 480p bis 1080p, 5 oder 10 Sekunden und optionalem Hintergrundaudio

Animiert ein über `image_url` angegebenes Standbild, das als erstes Bild verwendet wird, anhand eines Bewegungs-`prompt` mit bis zu 1500 Zeichen. Wähle 480p, 720p oder 1080p sowie eine `duration` von 5 oder 10 Sekunden. Ein optionales `audio_url` liefert den Soundtrack und wird abgeschnitten, wenn er länger als der Clip ist. Prompt-Erweiterung, negativer Prompt und Seed werden unterstützt.

- Model id: `wan-25-preview/image-to-video`
- Made by: Alibaba
- Category: Image to Video
- Output: video
- Price: from $0.05 / second (5 s ≈ $0.25) (cheapest run $0.25 (250 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan-25-preview/image-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/wan-25-preview/image-to-video`
- Docs page: https://doitong.com/de/developers/models/wan-25-preview/image-to-video

## Pricing

Price: **from $0.05 / second (5 s ≈ $0.25)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 10).

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

- When `resolution` = 720p: $0.10 (100 API credits) / second
- When `resolution` = 1080p: $0.15 (150 API credits) / second

The full example input below costs $0.75 = 750 API credits (5 s × 150 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.com/v1/quote/wan-25-preview/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 |  | ≥ 1 characters | Textanweisungen zur gewünschten Bewegung im Video, auf 1500 Zeichen begrenzt. |
| `image_url` | `image` | string (image URL) | yes |  |  | Stellt eine öffentlich erreichbare Bild-URL oder eine Base64-Daten-URI bereit, um das erste Frame des Videos zu liefern. |
| `audio_url` | `audio` | string (audio URL) \| null | no |  |  | Hintergrundmusik über eine öffentlich zugängliche Audio-URL im WAV- oder MP3-Format, mit einer Länge von 3 bis 30 s und einer Größe von höchstens 15 MB. Die ausgewählte Dauer von 5 oder 10 Sekunden bestimmt den Schnittpunkt: Überschüssiges Audio wird verworfen, während bei einem kürzeren Titel der restliche Teil des Videos stumm bleibt. Beispiel: Bei 3 Sekunden Audio und einem 5 Sekunden langen Video ist während der ersten 3 Sekunden Ton zu hören, die letzten 2 Sekunden sind stumm. |
| `resolution` |  | enum (string) | no | `1080p` | `480p`, `720p`, `1080p` | Ausgabevideoauflösung: Wähle 480p, 720p oder 1080p. |
| `duration` |  | enum (string) | no | `5` | `5`, `10` | Länge des Ausgabevideos, wählbar mit 5 oder 10 Sekunden. |
| `negative_prompt` |  | string \| null | no |  |  | Negativer Prompt zur Angabe unerwünschter Inhalte, auf 500 Zeichen begrenzt. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Steuert, ob ein LLM den Prompt umschreibt. |
| `seed` |  | integer \| null | no |  |  | Seed für reproduzierbare Generierung. Bei None wird ein Seed zufällig ausgewählt. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Schalter für die Sicherheitsprüfung, dessen Deaktivierung eine Kontoberechtigung erfordert. Ohne diese Berechtigung wird jede Anfrage unabhängig von der Einstellung geprüft; true aktiviert die Prüfung. |

File parameters (`image`, `audio`) 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.com/v1/run/wan-25-preview/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.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/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/wan-25-preview/image-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",
    "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.com/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/wan-25-preview/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.com/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": "wan-25-preview/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.
