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" \
  -d '{
    "prompt": "your description",
    "aspect_ratio": "16:9"
  }'

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

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" \
  -d '{"image": "https://..."}'

Returns PNG with transparency.

Edit Image (FIBO-Edit) - No Mask Required

Edit any image with natural language instructions:

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

Python example:

from bria_client import BriaClient
client = BriaClient()
result = client.edit_image(image_url, "change the mug to red")
print(result['result']['image_url'])

Edit Image Region with Mask (FIBO-Edit)

For precise control over which region to edit:

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" \
  -d '{
    "image": "https://...",
    "mask": "https://...",
    "prompt": "what to generate in masked area"
  }'

Expand Image (Outpainting)

Extend image boundaries to new aspect ratio:

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

Upscale Image

Increase image resolution 2x or 4x:

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" \
  -d '{"image": "https://...", "scale": 2}'

Product Lifestyle Shot

Place a product in a lifestyle scene:

curl -X POST "https://engine.prod.bria-api.com/v2/image/edit/lifestyle_shot_by_text" \
  -H "api_token: $BRIA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image": "https://product-with-transparent-bg.png",
    "prompt": "modern kitchen countertop, natural morning light"
  }'

Asset Generation Workflows

Website Hero Images

Generate wide banner images for landing pages:

{
  "prompt": "Modern tech startup workspace with developers collaborating, bright natural lighting, clean minimal aesthetic",
  "aspect_ratio": "16:9",
  "negative_prompt": "cluttered, dark, low quality"
}

Tips for hero images:

• Use 16:9 for full-width banners
• Describe lighting and mood explicitly
• Include "professional", "high quality", "commercial" for polished results
• Specify "clean background" or "minimal" for text overlay space

Product Photography

Generate e-commerce style product shots:

{
  "prompt": "Professional product photo of [item] on white studio background, soft shadows, commercial photography lighting",
  "aspect_ratio": "1:1"
}

Then remove background for transparent PNG to composite anywhere:

{"image": "generated_image_url"}

Presentation Visuals

Generate slides-ready images:

{
  "prompt": "Abstract visualization of data analytics, blue and purple gradient, modern corporate style, clean composition with space for text",
  "aspect_ratio": "16:9"
}

Common presentation themes:

• "Abstract technology background" - tech slides
• "Business team collaboration" - culture slides
• "Growth chart visualization" - metrics slides
• "Minimalist geometric patterns" - section dividers

Document Graphics

Generate report or article images:

{
  "prompt": "Isometric illustration of cloud computing infrastructure, flat design, vibrant colors, white background",
  "aspect_ratio": "4:3"
}

Icons and Illustrations

For icons, generate then remove background:

{
  "prompt": "3D icon of a shield with checkmark, glossy material, soft gradient background, app icon style",
  "aspect_ratio": "1:1"
}

Then use RMBG-2.0 to get transparent PNG.

Social Media Assets

Instagram post (1:1):

{
  "prompt": "Lifestyle photo of coffee and laptop on wooden desk, morning light, cozy atmosphere",
  "aspect_ratio": "1:1"
}

Story/Reel (9:16):

{
  "prompt": "Vertical product showcase of smartphone, floating in gradient background, tech aesthetic",
  "aspect_ratio": "9:16"
}

---

Prompt Engineering Tips

Be Specific About Style

• "professional product photography" vs "casual snapshot"
• "flat design illustration" vs "3D rendered"
• "corporate modern" vs "playful colorful"

Specify Technical Details

• 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

Add these for polished results:

• "high quality", "professional", "commercial grade"
• "4K", "detailed", "sharp focus"
• "award-winning photography" (for photos)

Negative Prompts

Exclude unwanted elements:

• "blurry, low quality, pixelated"
• "text, watermark, logo"
• "cluttered, busy, messy"

---

Async Response Handling

All endpoints return async responses:

{
  "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})
        data = r.json()
        if data["status"] == "COMPLETED":
            return data["result"]["image_url"]
        if data["status"] == "FAILED":
            raise Exception(data.get("error"))
        time.sleep(2)

---

Batch & Parallel Image Generation

Generating Multiple Images Concurrently

For generating many images efficiently, launch requests in parallel and poll concurrently:

import asyncio
import aiohttp

async def generate_image(session, api_key, prompt, aspect_ratio="1:1"):
    """Launch a single generation request."""
    async with session.post(
        "https://engine.prod.bria-api.com/v2/image/generate",
        headers={"api_token": api_key, "Content-Type": "application/json"},
        json={"prompt": prompt, "aspect_ratio": aspect_ratio}
    ) as resp:
        return await resp.json()

async def poll_status(session, api_key, status_url, timeout=120):
    """Poll until complete or failed."""
    for _ in range(timeout // 2):
        async with session.get(status_url, headers={"api_token": api_key}) as resp:
            data = await resp.json()
            if data["status"] == "COMPLETED":
                return data["result"]["image_url"]
            if data["status"] == "FAILED":
                raise Exception(data.get("error", "Generation failed"))
        await asyncio.sleep()
     TimeoutError()

  ():
    
    semaphore = asyncio.Semaphore(max_concurrent)  

      ():
          semaphore:
              aiohttp.ClientSession()  session:
                
                result =  generate_image(session, api_key, prompt, aspect_ratio)
                
                  poll_status(session, api_key, result[])

    
    results =  asyncio.gather(*[generate_one(p)  p  prompts], return_exceptions=)
     results


prompts = [
    ,
    ,
    ,
    ,
]
image_urls = asyncio.run(generate_batch(, prompts, max_concurrent=))

Key points:

• Use asyncio.Semaphore to limit concurrent requests (recommended: 3-5)
• return_exceptions=True prevents one failure from canceling all requests
• Each result is either a URL string or an Exception object

TypeScript/Node.js Parallel Generation

type AspectRatio = "1:1" | "4:3" | "16:9" | "3:4" | "9:16";

interface BriaResponse {
  request_id: string;
  status_url: string;
}

interface BriaStatusResponse {
  status: "IN_PROGRESS" | "COMPLETED" | "FAILED";
  result?: { image_url: string };
  error?: string;
}

interface GenerateBatchResult {
  prompt: string;
  imageUrl: string | null;
  error: string | null;
}

async function generateBatch(
  apiKey: string,
  prompts: string[],
  aspectRatio: AspectRatio = "1:1",
  maxConcurrent = 5
): Promise<GenerateBatchResult[]> {
  const semaphore = { count: 0, max: maxConcurrent };

  async function withLimit<T>(:  <T>): <T> {
     (semaphore. >= semaphore.) {
        ( (r, ));
    }
    semaphore.++;
     {
        ();
    }  {
      semaphore.--;
    }
  }

    (): <> {
     ( () => {
      
       res =  (, {
        : ,
        : { : apiKey, :  },
        : .({ prompt, : aspectRatio })
      });
       { status_url } = ( res.())  ;

      
       ( i = ; i < ; i++) {
         statusRes =  (status_url, { : { : apiKey } });
         data = ( statusRes.())  ;
         (data. === )  data.!.;
         (data. === )   (data. || );
          ( (r, ));
      }
        ();
    });
  }

   results =  .(prompts.(generateOne));

   results.( ({
    : prompts[i],
    : result. ===  ? result. : ,
    : result. ===  ? result.. : 
  }));
}


 results =  (process..!, [
  ,
  ,
  
], , );

results.( {
   (r.) .();
   .();
});

## Pipeline Workflows

Chain multiple operations on images (generate → edit → remove background).

### Complete Pipeline Example

```python
async def product_pipeline(api_key, product_descriptions, scene_prompt):
    """
    Pipeline: Generate product → Remove background → Place in lifestyle scene
    """
    async with aiohttp.ClientSession() as session:
        results = []

        for desc in product_descriptions:
            # Step 1: Generate product image
            gen_result = await generate_image(session, api_key,
                f"Professional product photo of {desc} on white background, studio lighting",
                aspect_ratio="1:1")
            product_url = await poll_status(session, api_key, gen_result["status_url"])

            # Step 2: Remove background
            async with session.post(
                "https://engine.prod.bria-api.com/v2/image/edit/remove_background",
                headers={"api_token": api_key, "Content-Type": "application/json"},
                json={"image": product_url}
            ) as resp:
                rmbg_result = await resp.json()
            transparent_url = await poll_status(session, api_key, rmbg_result["status_url"])

            # Step 3: Place in lifestyle scene
            async with session.post(
                "https://engine.prod.bria-api.com/v2/image/edit/lifestyle_shot_by_text",
                headers={"api_token": api_key, "Content-Type": "application/json"},
                json={"image": transparent_url, "prompt": scene_prompt}
            ) as resp:
                lifestyle_result = await resp.json()
            final_url = await poll_status(session, api_key, lifestyle_result["status_url"])

            results.append({
                "product": desc,
                "original": product_url,
                "transparent": transparent_url,
                "lifestyle": final_url
            })

        return results

# Usage
products = ["coffee mug", "water bottle", "notebook"]
scene = "modern minimalist desk, natural morning light, plants in background"
results = asyncio.run(product_pipeline("YOUR_API_KEY", products, scene))

Parallel Pipeline (Advanced)

Process multiple products through the pipeline concurrently:

async def parallel_pipeline(api_key, products, scene_prompt, max_concurrent=3):
    """Run full pipeline for multiple products in parallel."""
    semaphore = asyncio.Semaphore(max_concurrent)

    async def process_one(product):
        async with semaphore:
            return await single_product_pipeline(api_key, product, scene_prompt)

    return await asyncio.gather(*[process_one(p) for p in products], return_exceptions=True)

Common Pipeline Patterns

Pipeline	Steps	Use Case
Product → Transparent	generate → remove_background	E-commerce cutouts
Product → Lifestyle	generate → remove_background → lifestyle_shot	Marketing photos
Edit → Upscale	edit → increase_resolution	High-res edited images
Generate → Restyle	generate → restyle	Artistic variations
Generate → Variations	generate (num_results=4)	A/B testing options

Integration Examples

React/Next.js Component

// Generate and display a hero image
const [imageUrl, setImageUrl] = useState(null);

async function generateHero(prompt) {
  const res = await fetch('/api/bria/generate', {
    method: 'POST',
    body: JSON.stringify({ prompt, aspect_ratio: '16:9' })
  });
  const { image_url } = await res.json();
  setImageUrl(image_url);
}

Python Script for Batch Generation

import asyncio

# See "Batch & Parallel Image Generation" section for generate_batch function

async def main():
    api_key = "YOUR_API_KEY"
    products = ["running shoes", "leather bag", "smart watch"]
    prompts = [f"Professional product photo of {p} on white background" for p in products]

    results = await generate_batch(api_key, prompts, aspect_ratio="1:1", max_concurrent=3)

    for product, result in zip(products, results):
        if isinstance(result, Exception):
            print(f"{product}: FAILED - {result}")
        else:
            print(f"{product}: {result}")

asyncio.run(main())
