# FLUX 2 Edit API

> Deasachadh ann an cànan nàdarra de suas ri 4 ìomhaighean cuir a-steach, le roghainnean stiùiridh, àireamh cheuman agus leudachaidh prompt

Deasaichidh e ìomhaighean bho stiùireadh teacsa agus suas ri 4 ìomhaighean ann an `image_urls` (thèid na bharrachd a leigeil seachad). Atharraich `guidance_scale` (0 gu 20), 4 gu 50 ceum co-dhùnaidh agus leudachadh prompt roghainneil. Faodar meud an às-chuir a thaghadh bho ro-shuidheachaidhean eadar 512 agus 2048 piogsail, suas ri 4 ìomhaighean, mar jpeg, png no 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.ru/v1/run/flux-2/edit`
- Quote: `POST https://api.doitong.ru/v1/quote/flux-2/edit`
- Docs page: https://doitong.com/gd/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.ru/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 |  |  | Prompt a’ mìneachadh nan deasachaidhean ìomhaigh. |
| `guidance_scale` |  | number | no | `2.5` | 0 – 20 | Suidheachadh gèillidh a’ mhodail don prompt ann a bhith a’ lorg ìomhaigh cheangailte ri nochdadh, air a chur an cèill mar sgèile stiùiridh. |
| `seed` |  | integer \| null | no |  |  | Sgrìobhadh thairis air seed gineadh; ma thèid fhàgail às, taghaidh gineadh seed air thuaiream. |
| `num_inference_steps` |  | integer | no | `28` | 4 – 50 | Àireamh nan ceumannan co-dhùnaidh ri ruith. |

| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Àireamh nan ìomhaighean a chaidh iarraidh airson gineadh. |
| `acceleration` |  | enum (string) | no | `regular` | `none`, `regular`, `high` | Suidheachadh luathachaidh airson ìomhaighean a ghineadh. |
| `enable_prompt_expansion` |  | boolean | no | `false` |  | Leasachadh fèin-obrachail air prompt: bidh true a’ comasachadh leudachadh a’ prompt gus toraidhean a leasachadh. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Sgrùdadh sàbhailteachd, a thilleas ìomhaighean dubha an àite ìomhaighean sam bith a chaidh an comharrachadh mar mhì-shàbhailte. Bidh true a’ comasachadh sgrùdaidh; cuiridh false à comas e dìreach airson chunntasan ùghdarraichte, agus thèid iarrtasan gun ùghdarras a sgrùdadh co-dhiù. |
| `output_format` |  | enum (string) | no | `png` | `jpeg`, `png`, `webp` | Cruth faidhle na h-ìomhaigh a thig às. |
| `image_urls` | `images` | array of image URL | yes |  |  | Ìomhaighean tùsail deasachaidh air an solarachadh mar URLan; bidh giullachd a’ cleachdadh 4 inntrigidhean aig a’ char as motha, agus a’ leigeil seachad rud sam bith às dèidh a’ chiad 4. |

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.ru/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.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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.ru/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.ru/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.
