+| WHOOGLE_CSE_ID       | Your Custom Search Engine ID (cx parameter)                                               |
+| WHOOGLE_USE_CSE      | Enable Custom Search API by default (set to '1' to enable)                                |
+
+## Google Custom Search (BYOK)
+
+If Google blocks traditional search scraping (captchas, IP bans), you can use your own Google Custom Search Engine credentials as a fallback. This uses Google's official API with your own quota.
+
+### Why Use This?
+
+- **Reliability**: Official API never gets blocked or rate-limited (within quota)
+- **Speed**: Direct JSON responses are faster than HTML scraping
+- **Fallback**: Works when all scraping workarounds fail
+- **Privacy**: Your searches still don't go through third parties—they go directly to Google with your own API key
+
+### Limitations vs Standard Whoogle
+
+| Feature          | Standard Scraping        | CSE API             |
+|------------------|--------------------------|---------------------|
+| Daily limit      | None (until blocked)     | 100 free, then paid |
+| Image search     | ✅ Full support          | ✅ Supported         |
+| News/Videos tabs | ✅                       | ❌ Web results only  |
+| Speed            | Slower (HTML parsing)    | Faster (JSON)       |
+| Reliability      | Can be blocked           | Always works        |
+
+### Setup Steps
+
+#### 1. Create a Custom Search Engine
+1. Go to [Programmable Search Engine](https://programmablesearchengine.google.com/controlpanel/all)
+2. Click **"Add"** to create a new search engine
+3. Under "What to search?", select **"Search the entire web"**
+4. Give it a name (e.g., "My Whoogle CSE")
+5. Click **"Create"**
+6. Copy your **Search Engine ID** 
+
+#### 2. Get an API Key
+1. Go to [Google Cloud Console](https://console.cloud.google.com/)
+2. Create a new project or select an existing one
+3. Go to **APIs & Services** → **Library**
+4. Search for **"Custom Search API"** and click **Enable**
+5. Go to **APIs & Services** → **Credentials**
+6. Click **"Create Credentials"** → **"API Key"**
+7. Copy your API key (looks like `AIza...`)
+
+#### 3. (Recommended) Restrict Your API Key
+To prevent misuse if your key is exposed:
+1. Click on your API key in Credentials
+2. Under **"API restrictions"**, select **"Restrict key"**
+3. Choose only **"Custom Search API"**
+4. Under **"Application restrictions"**, consider adding IP restrictions if using on a server
+5. Click **Save**
+
+#### 4. Configure Whoogle
+
+**Option A: Via Settings UI**
+1. Open your Whoogle instance
+2. Click the **Config** button
+3. Scroll to "Google Custom Search (BYOK)" section
+4. Enter your API Key and CSE ID
+5. Check "Use Custom Search API"
+6. Click **Apply**
+
+**Option B: Via Environment Variables**
+```bash
+WHOOGLE_CSE_API_KEY=AIza...
+WHOOGLE_CSE_ID=23f...
+WHOOGLE_USE_CSE=1
+```
+
+### Pricing & Avoiding Charges
+
+| Tier | Queries          | Cost                  |
+|------|------------------|-----------------------|
+| Free | 100/day          | $0                    |
+| Paid | Up to 10,000/day | $5 per 1,000 queries  |
+
+**⚠️ To avoid unexpected charges:**
+
+1. **Don't add a payment method** to Google Cloud (safest option—API stops at 100/day)
+2. **Set a billing budget alert**: [Billing → Budgets & Alerts](https://console.cloud.google.com/billing/budgets)
+3. **Cap API usage**: APIs & Services → Custom Search API → Quotas → Set "Queries per day" to 100
+4. **Monitor usage**: APIs & Services → Custom Search API → Metrics
+
+### Troubleshooting
+
+| Error               | Cause                     | Solution                                                        |
+|---------------------|---------------------------|-----------------------------------------------------------------|
+| "API key not valid" | Invalid or restricted key | Check key in Cloud Console, ensure Custom Search API is enabled |
+| "Quota exceeded"    | Hit 100/day limit         | Wait until midnight PT, or enable billing                       |
+| "Invalid CSE ID"    | Wrong cx parameter        | Copy ID from Programmable Search Engine control panel           |
+
 ## Usage
 Same as most search engines, with the exception of filtering by time range.
