# Wan v2.6 Image to Image API

> Επεξεργάζεται ή αλλάζει το στυλ χρησιμοποιώντας 1-3 εικόνες αναφοράς και prompt, με έως 4 εξόδους ανά αίτημα

Μοντέλο image-to-image που δέχεται `prompt` έως 2000 χαρακτήρων στα κινεζικά ή στα αγγλικά και 1 έως 3 εικόνες αναφοράς στο `image_urls`. Αναφερθείτε σε αυτές ως image 1, image 2 και image 3 στο prompt, για παράδειγμα για συνδυασμό ενός στυλ με διαφορετικό φόντο. Διατίθενται έξι προεπιλογές `image_size` και το `num_images` είναι 1-4. Προαιρετικά `negative_prompt` και επέκταση prompt.

- Model id: `wan/v2.6/image-to-image`
- Made by: Alibaba
- Category: Image Editing
- Output: image
- Price: $0.03 / image (cheapest run $0.03 (30 API credits))
- Run: `POST https://api.doitong.com/v1/run/wan/v2.6/image-to-image`
- Quote: `POST https://api.doitong.com/v1/quote/wan/v2.6/image-to-image`
- Docs page: https://doitong.com/el/developers/models/wan/v2.6/image-to-image

## Pricing

Price: **$0.03 / image**. Billed per generated image (`num_images`, default 1).

The full example input below costs $0.03 = 30 API credits (1 image × 30 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/v2.6/image-to-image` 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 | Οδηγίες παραγωγής εικόνας στα κινεζικά ή αγγλικά, έως 2000 χαρακτήρες. Παράδειγμα: 'Generate an image using the style of image 1 and background of image 2'. |
| `image_urls` | `images` | array of image URL | yes |  |  | Παρέχετε 1–3 εικόνες αναφοράς επεξεργασίας σε μορφή JPEG, JPG, PNG (χωρίς alpha), BMP ή WEBP. Κάθε αρχείο πρέπει να είναι έως 10MB, με πλάτος και ύψος από 384–5000px. Αναφερθείτε σε αυτές στο prompt ως 'image 1', 'image 2' και 'image 3', σύμφωνα με τη σειρά παροχής τους. |
| `negative_prompt` |  | string \| null | no | `` |  | Περιεχόμενο προς αποκλεισμό από την τελική εικόνα, έως 500 χαρακτήρες. |
| `image_size` |  | object {width, height} \| enum (string) | no | `square_hd` | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Ορίστε τις διαστάσεις εξόδου με συνολικό πλήθος pixel από 768*768 έως 1280*1280. Επιλέξτε προεπιλογή όπως 'square_hd', 'landscape_16_9' ή 'portrait_9_16', ή δώστε ακριβείς διαστάσεις με ImageSize(width=1280, height=720). |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Πλήθος εικόνων για παραγωγή, από 1 έως 4. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Ενεργοποίηση βελτιστοποίησης prompt από LLM με κόστος επιπλέον 3–4 δευτερολέπτων επεξεργασίας. Τα απλά prompt ωφελούνται από σημαντικά βελτιωμένα αποτελέσματα. |
| `seed` |  | integer \| null | no |  |  | Τυχαίο seed που βελτιώνει τη συνέπεια όταν επαναχρησιμοποιείται και υποστηρίζει την αναπαραγωγιμότητα με τιμές από 0 έως 2147483647. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Εποπτεία τόσο της εισόδου όσο και της εξόδου, που επιβάλλεται σε κάθε αίτημα εκτός αν ο λογαριασμός είναι εξουσιοδοτημένος να την απενεργοποιήσει και η επιλογή είναι απενεργοποιημένη. |

File parameters (`images`) 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",
  "images": [
    "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_urls": [
    "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/v2.6/image-to-image?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_urls": [
      "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/v2.6/image-to-image?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_urls": [
      "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_urls": [
        "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/v2.6/image-to-image", 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/v2.6/image-to-image",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "image_urls": [
          "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.
