## How Auto-Routing Works

```bash
"iPhone 16 price"              → Serper (shopping keywords)
"how does quantum computing work" → Tavily (research question)
"latest AI policy updates in Germany" → Querit (multilingual + recency)
"companies like stripe.com"    → Exa (URL detected, similarity)
"events in Graz this weekend"  → Perplexity (local + direct answer)
"latest news on AI"            → You.com (real-time intent)
"search privately"             → SearXNG (privacy keywords)
```

## Security

**SearXNG SSRF Protection:** The SearXNG instance URL is validated with defense-in-depth:
- Enforces `http`/`https` schemes only
- Blocks cloud metadata endpoints (169.254.169.254, metadata.google.internal)
- Resolves hostnames and blocks private/internal IPs (loopback, RFC1918, link-local, reserved)
- Operators who intentionally self-host on private networks can set `SEARXNG_ALLOW_PRIVATE=1`
