# FLUX.2 [pro] API

> מודל FLUX.2 לייצור של Black Forest Labs, מותאם לתוצאות מלוטשות ופוטוריאליסטיות ללא פרמטרים לכוונון.

רמת ה־pro המנוהלת של FLUX.2: ללא ספירת שלבים או הנחיה לכוונון, רק הנחיה וגודל, עם פלט המיועד לצילום מסחרי, צילומי מוצר וחומרי קמפיין. תמונה אחת בכל בקשה בגודל מוגדר מראש או מותאם אישית, JPEG או PNG. גרעין מאפשר לקבלת תוצאות שניתן לשחזר.

- Price per megapixel of your output image: $0.015 / megapixel of output image (cheapest run $0.015 (15 API credits))
- Run: `POST https://api.doitong.com/v1/run/flux-2-pro`

## Pricing

Price: **$0.015 / megapixel of output image**. Price per megapixel of your output image: 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 $0.03 = 30 API credits (1 MP output image × $0.015 + $0.015).

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-pro` 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

## Example input

Required parameters only:

```json
{
  "prompt": "Studio product photo of a ceramic coffee cup on a linen napkin, morning window light, soft shadows"
}
```

A fuller example:

```json
{
  "prompt": "Studio product photo of a ceramic coffee cup on a linen napkin, morning window light, soft shadows",
  "image_size": "square_hd"
}
```

## 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-pro?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "Studio product photo of a ceramic coffee cup on a linen napkin, morning window light, soft shadows",
    "image_size": "square_hd"
  }'

# 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-pro?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "Studio product photo of a ceramic coffee cup on a linen napkin, morning window light, soft shadows",
    "image_size": "square_hd"
  }),
});
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": "Studio product photo of a ceramic coffee cup on a linen napkin, morning window light, soft shadows",
    "image_size": "square_hd",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/flux-2-pro", 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-pro",
      "input": {
        "prompt": "Studio product photo of a ceramic coffee cup on a linen napkin, morning window light, soft shadows",
        "image_size": "square_hd"
      },
      "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.
