Bria — Generate, Edit & Remove Background from Images with AI

Generate, edit, and create visual assets using Bria's commercially-safe AI models (FIBO, RMBG-2.0, GenFill, and more). Remove or replace backgrounds, create product lifestyle shots, generate transparent PNGs, batch generate images, and build pipeline workflows. Unlike black-box generators, Bria gives you fine-grained control: edit by text instruction, mask specific regions, add/replace/remove individual objects, change lighting or season independently.

Setup — API Key Check

Before making any Bria API call, check for the API key and help the user set it up if missing:

Step 1: Check if the key exists

echo $BRIA_API_KEY

If the output is not empty, skip to the next section.

Step 2: If the key is missing, guide the user

Tell the user exactly this:

To use image generation, you need a free Bria API key.

1. Go to https://platform.bria.ai/console/account/api-keys
2. Sign up or log in
3. Click Create API Key

Wait for the user to provide their API key. Do not proceed until they give you the key.

Do not proceed with any image generation or editing until the API key is confirmed set.

Quick Reference

Generate an Image (FIBO)

curl -X POST "https://engine.prod.bria-api.com/v2/image/generate" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{
    "prompt": "your description",
    "aspect_ratio": "16:9",
    "resolution": "1MP",
    "sync": true
  }'

Aspect ratios: 1:1 (square), 16:9 (hero/banner), 4:3 (presentation), 9:16 (mobile/story), 3:4 (portrait)

Resolution: 1MP (default) or 4MP (improved details for photorealism, adds ~30s latency)

Sync mode: Pass "sync": true in the request body for single image generation to get the result directly in the response. For batch/multiple image generation, omit sync (or set false) and use polling instead.

Advanced: For precise, deterministic control over generation, use VGL structured prompts instead of natural language. VGL defines every visual attribute (objects, lighting, composition) as explicit JSON.

Remove Background (RMBG-2.0)

curl -X POST "https://engine.prod.bria-api.com/v2/image/edit/remove_background" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{"image": "https://..."}'

Returns PNG with transparency.

Edit Image (FIBO-Edit) - No Mask Required

curl -X POST "https://engine.prod.bria-api.com/v2/image/edit" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{
    "images": ["https://..."],
    "instruction": "change the mug to red"
  }'

Edit Image Region with Mask (GenFill)

curl -X POST "https://engine.prod.bria-api.com/v2/image/edit/gen_fill" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{
    "image": "https://...",
    "mask": "https://...",
    "prompt": "what to generate in masked area"
  }'

Expand Image (Outpainting)

curl -X POST "https://engine.prod.bria-api.com/v2/image/edit/expand" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{
    "image": "base64-or-url",
    "aspect_ratio": "16:9",
    "prompt": "coffee shop background, wooden table"
  }'

Upscale Image

curl -X POST "https://engine.prod.bria-api.com/v2/image/edit/increase_resolution" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{"image": "https://...", "scale": 2}'

Create Product Lifestyle Shot

curl -X POST "https://engine.prod.bria-api.com/v1/product/lifestyle_shot_by_text" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{
    "image": "https://product-with-transparent-bg.png",
    "prompt": "modern kitchen countertop, natural morning light"
  }'

Integrate Products into Scene

Place one or more products at exact coordinates in a scene. Products are automatically cut out and matched to the scene's lighting and perspective.

curl -X POST "https://engine.prod.bria-api.com/image/edit/product/integrate" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -H "User-Agent: BriaSkills/1.2.5" \
  -d '{
    "scene": "https://scene-image-url",
    "products": [
      {
        "image": "https://product-image-url",
        "coordinates": {"x": 100, "y": 200, "width": 300, "height": 400}
      }
    ]
  }'

Response Handling

Sync (single image generation)

For single image requests, pass "sync": true in the request body. The response returns the result directly — no polling needed.

Async with polling (batch generation)

For batch or multiple image generation, omit sync (or set "sync": false). The response returns a status URL to poll:

{
  "request_id": "uuid",
  "status_url": "https://engine.prod.bria-api.com/v2/status/uuid"
}

Poll the status_url until status: "COMPLETED", then get result.image_url.

import requests, time

def get_result(status_url, api_key):
    while True:
        r = requests.get(status_url, headers={"api_token": api_key, "User-Agent": "BriaSkills/1.2.5"})
        data = r.json()
        if data["status"] == "COMPLETED":
            return data["result"]["image_url"]
        if data["status"] == "FAILED":
            raise Exception(data.get("error"))
        time.sleep(2)

Prompt Engineering Tips

• Style: "professional product photography" vs "casual snapshot", "flat design illustration" vs "3D rendered"
• Lighting: "soft natural light", "studio lighting", "dramatic shadows"
• Background: "white studio", "gradient", "blurred office", "transparent"
• Composition: "centered", "rule of thirds", "negative space on left for text"
• Quality keywords: "high quality", "professional", "commercial grade", "4K", "sharp focus"
• Negative prompts: "blurry, low quality, pixelated", "text, watermark, logo"
