# FLUX 2 Edit API

> עריכה בשפה טבעית של עד 4 תמונות קלט, עם אפשרויות להנחיה, מספר צעדים והרחבת הנחיה

עורך תמונות לפי הוראת טקסט ועד 4 תמונות ב-`image_urls` (נוספות מתעלמות). ניתן לכוונן את `guidance_scale` (0 עד 20), 4 עד 50 צעדי הסקה והרחבת הנחיה אופציונלית. ניתן לבחור פלט מגדלים מוגדרים מראש בין 512 ל-2048 פיקסלים, עד 4 תמונות, בפורמט jpeg, png או webp.

- Model id: `flux-2/edit`
- Made by: Black Forest Labs
- Category: Image Editing
- Output: image
- Price per megapixel: $0.012 / megapixel (cheapest run $0.012 (12 API credits))
- Run: `POST https://api.doitong.com/v1/run/flux-2/edit`
- Quote: `POST https://api.doitong.com/v1/quote/flux-2/edit`
- Docs page: https://doitong.com/he/developers/models/flux-2/edit

## Pricing

Price: **$0.012 / megapixel**. Price per megapixel: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.024 = 24 API credits (2 MP × $0.012).

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/flux-2/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 |  |  | הנחיה המתארת את עריכות התמונה. |
| `guidance_scale` |  | number | no | `2.5` | 0 – 20 | הגדרת ההיצמדות להנחיה בחיפוש המודל אחר תמונה קשורה להצגה, מבוטאת כסולם הנחיה. |
| `seed` |  | integer \| null | no |  |  | עקיפת Seed היצירה; השמטתו מאפשרת ליצירה לבחור Seed באקראי. |
| `num_inference_steps` |  | integer | no | `28` | 4 – 50 | מספר שלבי ההסקה לביצוע. |
| `image_size` |  | object {width, height} \| enum (string) \| null | no |  | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | גודל תמונת הפלט, מוגבל למינימום של 512 ולמקסימום של 2048 פיקסלים בכל ציר. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | מספר התמונות המבוקש ליצירה. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular`, `high` | הגדרת האצה ליצירת תמונות. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | שיפור אוטומטי של ההנחיה: true מפעיל הרחבה של ההנחיה לשיפור התוצאות. |
| `enable_safety_checker` |  | boolean | no | `true` |  | בדיקת בטיחות, שמחזירה תמונות שחורות במקום תמונות שסומנו כלא בטוחות. ערך true מאפשר את הבדיקה; false משבית אותה רק עבור חשבונות מורשים, בעוד שבקשות ללא הרשאה נבדקות בכל מקרה. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | פורמט הקובץ של התמונה שהתקבלה. |
| `image_urls` | `images` | array of image URL | yes |  |  | תמונות מקור לעריכה שסופקו ככתובות URL; העיבוד משתמש ב-4 רשומות לכל היותר ומתעלם מכל מה שאחרי ארבע הרשומות הראשונות. |

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/flux-2/edit?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/flux-2/edit?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/flux-2/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": "flux-2/edit",
      "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.
