/*
 * FCS API - Authentication Example
 * Get your API key at: https://fcsapi.com
 *
 * This example shows different authentication methods:
 * 1. Default config (from FcsConfig.java)
 * 2. Direct API key
 * 3. IP Whitelist (no key needed)
 * 4. Token-based (for frontend security)
 *
 * Run: javac -cp ".:../../lib/*" AuthExample.java && java -cp ".:../../lib/*" AuthExample
