/**
 * InsumerAPI — XRPL verification examples
 *
 * Demonstrates every XRPL verification scenario:
 * 1. Native XRP balance check
 * 2. RLUSD trust line token verification
 * 3. USDC trust line token verification
 * 4. Multi-condition (XRP + RLUSD in one call)
 * 5. NFT ownership on XRPL
 * 6. Trust profile with XRPL dimensions (requires EVM wallet + xrplWallet)
 *
 * Usage:
 *   INSUMER_API_KEY=insr_live_... node verify-xrpl.js
 *
 * Get a free key:
 *   curl -X POST https://api.insumermodel.com/v1/keys/create \
