When to prefer

Use this endpoint when you need to programmatically query a user's onchain ERC-20 loyalty token balance on Base L2, especially within the Loyal Spark ecosystem. Prefer this over general blockchain explorers when you need a clean, structured JSON response ready for agent workflows or loyalty program automation.

Side effects

Invalid or malformed wallet address returns an error response
Contract address not found on Base L2 returns empty or error
Network congestion or RPC timeout causes delayed or failed response
Wallet with zero balance returns 0 rather than an error
Payment of $0.01 USDC via x402 fails due to insufficient funds
