Also triggers on cutout, inpainting, outpainting, object removal or addition, photo restoration, style transfer, image enhancement, relight, reseason, sketch-to-photo, or any visual content creation. Commercially safe, royalty-free. 20+ specialized endpoints for e-commerce, web design, and content pipelines. license: MIT metadata: author: Bria AI version: "1.2.7" --- # Bria — AI Image Generation, Editing & Background Removal Commercially safe, royalty-free image generation and editing through 20+ API endpoints. Generate from text, edit with natural language, remove backgrounds, create product shots, and build automated image pipelines. If you are stuck on request shapes, parameters, or endpoints not covered here, **fetch the full agent-oriented API reference** at [docs.bria.ai/llms.txt](https://docs.bria.ai/llms.txt) — it is the canonical LLM-ready documentation and the right place to look before guessing. ## When to Use This Skill Use this skill when the user wants to: - **Generate images** — "create an image of...", "make me a banner", "generate a hero image", "I need a product photo" - **Edit images** — "change the background", "make it look like winter", "add a vase to the table", "remove the person" - **Remove/replace backgrounds** — "make the background transparent", "cut out the product", "replace with a studio background" - **Product photography** — "create a lifestyle shot", "place this product in a kitchen scene", "e-commerce packshot" - **Enhance/transform** — "upscale this image", "make it higher resolution", "restyle as oil painting", "change the lighting" - **Batch/pipeline** — "generate 10 product images", "process all these images", "remove backgrounds in bulk" This skill handles the full spectrum of AI image operations. If the user mentions images, photos, visuals, or any visual content creation — use this skill. --- ## What You Can Build - **E-commerce product catalog** — Generate product photos, remove backgrounds for transparent PNGs, place products in lifestyle scenes (kitchen, office, outdoor), create packshots with consistent style - **Landing page visuals** — Generate hero images, abstract tech backgrounds, team photos, and section illustrations — all matching your brand aesthetic - **Social media content** — Instagram posts (1:1), Stories/Reels (9:16), LinkedIn banners (16:9), ad creatives — batch-generate variants for A/B testing - **Marketing campaign assets** — Seasonal transformations (summer→winter), restyle product shots for different markets, create localized visuals at scale - **Photo restoration pipeline** — Restore old damaged photos, colorize black & white images, upscale low-res photos to 4x, enhance quality automatically - **Brand asset toolkit** — Remove backgrounds from logos, blend artwork onto products (t-shirts, mugs), create consistent product photography across your entire catalog - **AI-powered design workflows** — Chain operations: generate→edit→remove background→place in scene→upscale — all automated through API pipelines --- ## Setup — Authentication Before making any API call, you need a valid Bria access token. ### Step 1: Check for existing credentials ```bash if [ -f ~/.bria/credentials ]; then BRIA_ACCESS_TOKEN=$(grep '^access_token=' "$HOME/.bria/credentials" | cut -d= -f2-) BRIA_API_KEY=$(grep '^api_token=' "$HOME/.bria/credentials" | cut -d= -f2-) fi if [ -z "$BRIA_ACCESS_TOKEN" ]; then echo "NO_CREDENTIALS" elif [ -n "$BRIA_API_KEY" ]; then echo "READY" else echo "CREDENTIALS_FOUND" fi ``` If the output is `READY`, skip straight to making API calls — no introspection needed. If the output is `CREDENTIALS_FOUND`, skip to Step 3. If the output is `NO_CREDENTIALS`, proceed to Step 2. ### Step 2: Authenticate via device authorization Start the device authorization flow: **2a. Request a device code:** ```bash DEVICE_RESPONSE=$(curl -s -X POST "https://engine.prod.bria-api.com/v2/auth/device/authorize" \ -H "Content-Type: application/json") echo "$DEVICE_RESPONSE" ``` Parse the response fields: - `device_code` — used to poll for the token (keep this, don't show to user) - `user_code` — the code the user must enter (e.g. `BRIA-XXXX`) - `interval` — seconds between poll attempts **2b. Show the user a single sign-in link.** Tell them exactly this — nothing more: > **Connect your Bria account:** [Click here to sign in](https://platform.bria.ai/device/verify?user_code={user_code}) > Your code is **{user_code}** — it's already filled in. Do NOT show two links. Do NOT show the raw URL separately. Do NOT use `verification_uri` from the API response. Keep it to one clickable link. **2c. Poll for the token.** After showing the user the code, immediately start polling. Try up to 60 times with the given interval (default 5 seconds): ```bash for i in $(seq 1 60); do TOKEN_RESPONSE=$(curl -s -X POST "https://engine.prod.bria-api.com/v2/auth/token" \ -d "grant_type=urn:ietf:params:oauth:grant-type:device_code" \ -d "device_code=$DEVICE_CODE") ACCESS_TOKEN=$(printf '%s' "$TOKEN_RESPONSE" | sed -n 's/.*"access_token" *: *"\([^"]*\)".*/\1/p') if [ -n "$ACCESS_TOKEN" ]; then BRIA_ACCESS_TOKEN="$ACCESS_TOKEN" REFRESH_TOKEN=$(printf '%s' "$TOKEN_RESPONSE" | sed -n 's/.*"refresh_token" *: *"\([^"]*\)".*/\1/p') mkdir -p ~/.bria printf 'access_token=%s\nrefresh_token=%s\n' "$BRIA_ACCESS_TOKEN" "$REFRESH_TOKEN" > "$HOME/.bria/credentials" echo "AUTHENTICATED" break fi sleep 5 done ``` If the output contains `AUTHENTICATED`, proceed to Step 3. Otherwise the code expired — start over from Step 2a. **Do not proceed with any API call until authentication is confirmed.** ### Step 3: Verify billing status and resolve API key Introspect the bearer token to check billing status and obtain the real API key for Bria API calls: ```bash INTROSPECT=$(curl -s -X POST "https://engine.prod.bria-api.com/v2/auth/token/introspect" \ -d "[REDACTED_SECRET]") BILLING_STATUS=$(printf '%s' "$INTROSPECT" | sed -n 's/.*"billing_status" *: *"\([^"]*\)".*/\1/p') if [ "$BILLING_STATUS" = "blocked" ]; then BILLING_MSG=$(printf '%s' "$INTROSPECT" | sed -n 's/.*"billing_message" *: *"\([^"]*\)".*/\1/p') echo "BILLING_ERROR: $BILLING_MSG" fi ACTIVE=$(printf '%s' "$INTROSPECT" | sed -n 's/.*"active" *: *\([^,}]*\).*/\1/p' | tr -d ' ') if [ "$ACTIVE" = "false" ]; then rm -f ~/.bria/credentials echo "TOKEN_EXPIRED" fi BRIA_API_KEY=$(printf '%s' "$INTROSPECT" | sed -n 's/.*"api_token" *: *"\([^"]*\)".*/\1/p') if [ -n "$BRIA_API_KEY" ]; then grep -v '^api_token=' "$HOME/.bria/credentials" > "$HOME/.bria/credentials.tmp" 2>/dev/null || true printf 'api_token=%s\n' "$BRIA_API_KEY" >> "$HOME/.bria/credentials.tmp" mv "$HOME/.bria/credentials.tmp" "$HOME/.bria/credentials" fi ``` Interpret the output: - If it prints `BILLING_ERROR: ...` — relay the message to the user exactly as shown and **stop**. Do not make any API calls. - If it prints `TOKEN_EXPIRED` — the session is no longer valid. Tell the user their session expired and restart from Step 2. - Otherwise, `BRIA_API_KEY` now contains the real API key and is cached for future calls. Proceed to the next section. --- ## Core Capabilities | Need | Capability | Use Case | |------|------------|----------| | Generate images from text | FIBO Generate | Hero images, product shots, illustrations, social media images, banners | | Edit images by text instruction | FIBO-Edit | Change colors, modify objects, transform scenes | | Edit image region with mask | GenFill/Erase | Precise inpainting, add/replace specific regions | | Add/Replace/Remove objects | Text-based editing | Add vase, replace apple with pear, remove table | | Remove background (transparent PNG) | RMBG-2.0 | Extract subjects for overlays, logos, cutouts | | Replace/blur/erase background | Background ops | Change, blur, or remove backgrounds | | Expand/outpaint images | Outpainting | Extend boundaries, change aspect ratios | | Upscale image resolution | Super Resolution | Increase resolution 2x or 4x | | Enhance image quality | Enhancement | Improve lighting, colors, details | | Restyle images | Restyle | Oil painting, anime, cartoon, 3D render | | Change lighting | Relight | Golden hour, spotlight, dramatic lighting | | Change season | Reseason | Spring, summer, autumn, winter | | Composite/blend images | Image Blending | Apply textures, logos, merge images | | Restore old photos | Restoration | Fix old/damaged photos | | Colorize images | Colorization | Add color to B&W, or convert to B&W | | Sketch to photo | Sketch2Image | Convert drawings to realistic photos | | Create product lifestyle shots | Lifestyle Shot | Place products in scenes for e-commerce | | Integrate products into scenes | Product Integrate | Embed products at exact coordinates | ## How to Call Any Endpoint Use `bria_call` for all API calls. It handles URL passthrough, local file base64 encoding, JSON construction, API call, and async polling in a single function call. The API key is auto-loaded from `~/.bria/credentials`. ```bash source ~/.agents/skills/bria-ai/references/code-examples/bria_client.sh # Generate (no image input — pass empty string) RESULT=$(bria_call /v2/image/generate "" '"prompt": "your description", "aspect_ratio": "16:9", "sync": true') # Remove background RESULT=$(bria_call /v2/image/edit/remove_background "/path/to/local/image.png") # Replace background RESULT=$(bria_call /v2/image/edit/replace_background "https://example.com/img.jpg" '"prompt": "sunset beach"') # Edit image (uses images array — pass --key images) RESULT=$(bria_call /v2/image/edit "/path/to/image.png" --key images '"instruction": "make it look warmer"') # Upscale RESULT=$(bria_call /v2/image/edit/increase_resolution "https://example.com/img.jpg" '"scale": 4') # Lifestyle shot RESULT=$(bria_call /v1/product/lifestyle_shot_by_text "/path/to/product.png" '"prompt": "modern kitchen countertop"') echo "$RESULT" ``` **Calling convention:** `bria_call <endpoint> <image_or_empty> [--key <json_key>] [extra JSON fields...]` - Pass a URL, local file path, or `""` (empty) for endpoints without image input - Use `--key images` when the endpoint expects an `images` array instead of `image` - Extra JSON fields are appended as key-value pairs: `'"key": "value"'` - Returns the result image URL on success, or prints an error to stderr **Generation options:** Aspect ratios `1:1`, `16:9`, `4:3`, `9:16`, `3:4`. Resolution `1MP` (default) or `4MP` (more detail, +30s). Pass `"sync": true` for single images. > **Advanced**: For precise control over generation, use **[VGL structured prompts](../vgl/SKILL.md)** instead of natural language. See **[API Endpoints Reference](references/api-endpoints.md)** for full parameter documentation on all 20+ endpoints. --- ## 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" ### Recipes by Use Case **Hero banner (16:9):** `"Modern tech startup workspace with developers collaborating, bright natural lighting, clean minimal aesthetic"` — include "clean background" or "minimal" for text overlay space **Product photo (1:1):** `"Professional product photo of [item] on white studio background, soft shadows, commercial photography lighting"` — then remove background for transparent PNG **Presentation visual (16:9):** `"Abstract visualization of data analytics, blue and purple gradient, modern corporate style, clean composition with space for text"` — common themes: "abstract technology", "business collaboration", "minimalist geometric patterns" **Instagram post (1:1):** `"Lifestyle photo of coffee and laptop on wooden desk, morning light, cozy atmosphere"` **Story/Reel (9:16):** `"Vertical product showcase of smartphone, floating in gradient background, tech aesthetic"` --- ## Additional Resources - **[API Endpoints Reference](references/api-endpoints.md)** — Complete endpoint documentation with request/response formats for all 20+ endpoints - **[Shell Client (bria_client.sh)](references/code-examples/bria_client.sh)** — Single-function helper: `bria_call` handles auth, base64, JSON, polling - **[Full API docs for agents (llms.txt)](https://docs.bria.ai/llms.txt)** — Agent-ready Bria API reference; use when this skill's summary is not enough ## Related Skills - **[vgl](../vgl/SKILL.md)** — Write structured VGL JSON prompts for precise, deterministic control over FIBO image generation - **[image-utils](../image-utils/SKILL.md)** — Classic image manipulation (resize, crop, composite, watermarks) for post-processing
