# Bria Expand (FIBO-Edit-1.5) API

> Outpainting-Tool, dat e Bild op en neit Aspektverhältnis oder eng personaliséiert Canvas ënner 25 Megapixel erweidert

Erweidert e Bild iwwer seng Grenzen eraus. Wiel ee vun néng `aspect_ratio`-Wäerter oder definéier `canvas_size` als [width, height] mat enger Fläch ënner 25 Megapixel, zesumme mat `original_image_size` an `original_image_location`. En optionalen `prompt` beschreift den neie Beräich. `retain_original_quality` an `preserve_alpha` si par défaut aktiv, an `return_model_output` ass fir Diagnostik geduecht.

- Made by: Bria AI
- Category: Image Editing
- Output: image
- Price: $0.04 / image (cheapest run $0.04 (40 API credits))
- Run: `POST https://api.doitong.com/v1/run/bria/fibo-edit-1.5/expand`
- Quote: `POST https://api.doitong.com/v1/quote/bria/fibo-edit-1.5/expand`

## Pricing

Price: **$0.04 / image**. Billed per generated image.

The full example input below costs $0.04 = 40 API credits (1 image × 40 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/bria/fibo-edit-1.5/expand` 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 |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | Bild fir d'Ausdehnung, als Datei oder URL geliwwert. |
| `canvas_size` |  | array of integer \| null | no |  | 2 – 2 items | Dimensioune vum erweiderten Bild, gekoppelt mat 'original_image_location'. Gitt [width, height] fir de Schlusscanvas un, mat enger Fläch ënner 25 Megapixel. |
| `aspect_ratio` |  | enum (string) \| null | no |  | `1:1`, `2:3`, `3:2`, `3:4`, `4:3`, `4:5`, `5:4`, `9:16`, `16:9` | Astellung vum Schlussbildverhältnis, déi d'Original zentréiert an de Canvas ronderëm erweidert. Hir Ugi huet Virrang virun 'original_image_size' an 'original_image_location'. |
| `original_image_size` |  | array of integer \| null | no |  | 2 – 2 items | Zil [width, height] fir d'Originalbild am Canvas. 'aspect_ratio' iwwerschreift dës Astellung; soss gëtt d'Bild virun der Plazéierung op dës Dimensioune vergréissert oder verkleinert. |
| `original_image_location` |  | array of integer \| null | no |  | 2 – 2 items | Plazéierungskoordinaten [x, y] vun der ieweschter lénkser Ecke vum Originalbild, ignoréiert, wann 'aspect_ratio' geliwwert gëtt. Plazéierung iwwer d'Canvasgrenze eraus ass erlaabt a beschneit d'Original. |
| `prompt` |  | string \| null | no |  |  | Optional Beschreiwung vum Inhalt fir de bäigefüügte Beräich. Eng einfach Canvas-Upassung brauch normalerweis keng Beschreiwung: d'Wegloossen freet de Modell einfach, dat bestoend Bild ze verlängeren. |
| `seed` |  | integer \| null | no |  | 0 – 2,147,483,647 | Seed fir zoufälleg Generatioun, ëmmer an der Äntwert abegraff, egal ob en hei geliwwert oder beim Wegloossen zoufälleg gewielt gouf. E Wäert aus enger fréierer Äntwert kann d'Resultat nei erstellen. |
| `negative_prompt` |  | string \| null | no |  |  | Kompatibilitéitscheck fir Ufroen, déi fir d'SDXL-Ausdehnungs-API-Route geschriwwe goufen: dësen net ënnerstëtzten Input auszufëllen léist eng explizit Oflehnung aus, sou datt säi Wäert net onbemierkt verluer geet. Benotzt amplaz 'prompt'. |
| `retain_original_quality` |  | boolean | no | `true` |  | Aktivéiert dëst, fir déi maskegeschützte Originalpixel a voller Opléisung ouni Neiskaléierung ze behalen. De Modell generéiert bei ongeféier engem Megapixel a skaléiert duerno fir méi grouss Canvassen erop. Beim Desaktivéiere gëtt d'Resultat iwwerall mëll, wat eng Fuge géint en texturéierten Hannergrond verstoppe kann. |
| `preserve_alpha` |  | boolean | no | `true` |  | Behält d'Transparenz vum Input, andeems den originale Alpha-Kanal duerch Kantenreplikatioun verlängert gëtt, wann néideg fir e Cutout auszebauen. Well d'Generatioun a RGB funktionéiert, produzéiert de Modell keen Alpha. Desaktivéiert dëst, fir e flaache RGB-Output ze kréien. |
| `return_model_output` |  | boolean | no | `false` |  | Gëtt en zousätzleche diagnostesche Frame zeréck, fir Modellfeeler vu Kompositiounsfeeler z'ënnerscheeden, ouni d'Schlussbild z'änneren. E weist d'Resultat vum Modell, ier d'Original nees agesat an d'Fuge verglach gëtt; e Grenzdefekt, dee schonn an dësem Frame sichtbar ass, ass e Generatiounsfeeler an net e Post-Processing-Feeler. |

File parameters (`image`) 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
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "image_url": "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/bria/fibo-edit-1.5/expand?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "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/bria/fibo-edit-1.5/expand?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "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 = {
    "image_url": "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/bria/fibo-edit-1.5/expand", 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": "bria/fibo-edit-1.5/expand",
      "input": {
        "image_url": "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.
