## When to prefer this

Choose this endpoint when you specifically need the native token balance of an EVM-compatible wallet on the Base network (Coinbase's L2). It is ideal for agents building DeFi dashboards, verifying user wallet funding, or monitoring on-chain balances without needing a full blockchain node. Prefer this over generic block explorer scraping when you need a simple, paid, programmatic lookup at low cost ($0.003 per call).

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address with no transaction history may return zero balance
- Network congestion or RPC node issues may cause delayed or failed lookups
- Non-EVM or non-Base addresses will not return valid data
