# Qwen Image 3 Edit API

> Mengedit dengan satu hingga tiga gambar referensi, unggul dalam mengubah atau menambahkan teks pada gambar.

Mode pengeditan Qwen Image 3 menerima satu hingga tiga gambar referensi (384 hingga 2048 px per sisi) dan instruksi yang dapat merujuknya sebagai image 1, image 2, dan image 3. Mode ini sangat baik untuk mengganti atau menambahkan tulisan. Biarkan ukuran kosong agar model memilihnya, atau tetapkan ukuran prasetel atau kustom hingga 2K; hingga enam hasil per permintaan.

- Model id: `alibaba/qwen-image-3/edit`

## Pricing

Price: **from $0.04 / image** (the lowest tier; the quote prices your exact input). Billed per generated image (`num_images`, default 1).

The full example input below costs $0.075 = 75 API credits (1 image × 75 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/alibaba/qwen-image-3/edit` 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 – 5000 characters | Teks yang menjelaskan pengeditan yang akan dilakukan, dalam bahasa Mandarin atau Inggris, dibatasi hingga 5000 karakter. |
| `negative_prompt` |  | string \| null | no | `` | ≤ 500 characters | Konten yang harus dikecualikan dari gambar hasil, dibatasi hingga 500 karakter. |
| `image_size` |  | object {width, height} \| enum (string) \| null | no |  | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | Dimensi gambar output, dibatasi oleh jumlah piksel total dari 512 × 512 hingga 2048 × 2048. Jika ukuran dihilangkan, model memilih resolusi secara otomatis. |
| `enable_prompt_expansion` |  | boolean | no | `true` |  | Mengontrol penulisan ulang prompt secara otomatis oleh LLM untuk meningkatkan hasil. |
| `seed` |  | integer \| null | no |  |  | Seed acak untuk memungkinkan hasil yang dapat direproduksi, dari 0 hingga 2147483647. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 6 | Jumlah gambar yang diminta untuk dibuat. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Format file untuk gambar hasil. |
| `image_urls` | `images` | array of image URL | yes |  |  | Berikan 1–3 referensi pengeditan dalam format JPEG, JPG, PNG (tanpa alpha), atau WEBP, dengan ukuran maksimal 10MB per file dan dimensi 384–2048px pada setiap sumbu. Rujuk dalam prompt sebagai 'image 1', 'image 2', dan 'image 3', sesuai urutan pemberiannya. |

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": "Change the text on the sneaker's side to read \"RUN\" in bold letters",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg"
  ]
}
```

A fuller example:

```json
{
  "prompt": "Change the text on the sneaker's side to read \"RUN\" in bold letters",
  "images": [
    "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.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/alibaba/qwen-image-3/edit?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Change the text on the sneaker'\''s side to read \"RUN\" in bold letters",
    "images": [
      "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.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/alibaba/qwen-image-3/edit?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "Change the text on the sneaker's side to read \"RUN\" in bold letters",
    "images": [
      "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.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": "Change the text on the sneaker's side to read \"RUN\" in bold letters",
    "images": [
        "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.jpg",
    ],
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/alibaba/qwen-image-3/edit", 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": "alibaba/qwen-image-3/edit",
      "input": {
        "prompt": "Change the text on the sneaker's side to read \"RUN\" in bold letters",
        "images": [
          "https://content.doitong.com/images/showcase/v3/gen_sneaker_ad.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.
