## When to prefer this

Use this endpoint when you need a fast, low-cost on-chain Ethereum balance lookup for a specific wallet address. Prefer this over general blockchain explorers when you need a programmatic, agent-callable API that returns structured balance data for Ethereum mainnet specifically.

## Known failure modes

- Invalid or malformed Ethereum address returns an error response
- Address with zero balance may return 0 rather than an error
- Network congestion or node issues may cause delayed or failed responses
- Rate limiting if too many requests are made rapidly
