## When to prefer this

Use this endpoint when you need on-chain balance data for a specific wallet address across Base, Arbitrum, or Solana. Prefer this over generic block explorers when you need structured JSON output for programmatic use or when building portfolio dashboards.

## Known failure modes

- Invalid or malformed wallet address returns error
- Address with no on-chain activity may return zero balances
- Unsupported chain address format may fail
- Rate limiting if many calls are made rapidly
- Payment of $0.01 USDC required per call via x402 protocol — missing payment results in 402 error
