# FLUX 2 Edit API

> Legfeljebb 4 bemeneti kép természetes nyelvű szerkesztése útmutatással, lépésszámmal és promptbővítési lehetőséggel

Szöveges utasítás és a `image_urls` paraméterben megadott legfeljebb 4 kép alapján szerkeszt képeket (a továbbiakat figyelmen kívül hagyja). Beállítható a `guidance_scale` (0–20), a 4–50 inferencialépés és az opcionális promptbővítés. A kimenet mérete 512 és 2048 pixel közötti előbeállításokból választható, legfeljebb 4 kép készülhet jpeg, png vagy webp formátumban.

- 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/hu/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 |  |  | A képszerkesztéseket leíró prompt. |
| `guidance_scale` |  | number | no | `2.5` | 0 – 20 | A promptkövetés beállítása a modell kapcsolódó megjelenítendő kép kereséséhez, guidance scale formájában. |
| `seed` |  | integer \| null | no |  |  | A generálási seed felülírása; kihagyásakor a generálás véletlenszerűen választ seedet. |
| `num_inference_steps` |  | integer | no | `28` | 4 – 50 | A végrehajtandó inferencialépések száma. |
| `image_size` |  | object {width, height} \| enum (string) \| null | no |  | `square_hd`, `square`, `portrait_4_3`, `portrait_16_9`, `landscape_4_3`, `landscape_16_9` | A kimeneti kép mérete, tengelyenként legalább 512, legfeljebb 2048 pixelre korlátozva. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | A generáláshoz kért képek száma. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular`, `high` | A képgenerálás gyorsítási beállítása. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Automatikus promptbővítés: a true engedélyezi a prompt kibővítését az eredmények javításához. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Biztonsági ellenőrzés, amely nem biztonságosnak jelölt képek helyett fekete képeket ad vissza. A true érték engedélyezi az ellenőrzést; a false csak jogosult fiókoknál kapcsolja ki, a jogosulatlan kéréseket pedig mindig ellenőrzi a rendszer. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | A létrejövő kép fájlformátuma. |
| `image_urls` | `images` | array of image URL | yes |  |  | URL-ként megadott szerkesztési forrásképek; a feldolgozás legfeljebb 4 bejegyzést használ, az első 4 utániakat figyelmen kívül hagyja. |

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.
