# 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.

For additional endpoint details beyond what is documented here, see the [Bria API reference for agents](https://docs.bria.ai/llms.txt).

## 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=$(curl -s -X POST "https://engine.prod.bria-api.com/v2/auth/token/introspect" \
  -d "token=$BRIA_ACCESS_TOKEN")
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 [ "$ACTIVE" = "false" ]; then
  # Clear stale tokens so re-auth starts fresh (credentials file is re-created in Step 2c)
  printf '' > "$HOME/.bria/credentials"
