```sh
zero fetch --capability geld-machen-base-balance-lookup-0657aa68
```

Example prompt: Can you pull a DeFi snapshot for the Base address 0xAbC123...def456 — I want to see the token balances, current gas, and any protocol TVL or APY data?

## When to prefer this

Use this endpoint when you need a combined on-chain snapshot of balances plus DeFi protocol metrics (TVL/APY) for a Base network address in a single call, and are willing to pay $0.01 USDC per lookup via x402 micropayment.

## Known failure modes

- Invalid or malformed EVM address returns an error
- Address with no activity may return empty balances
- Network connectivity issues to Base RPC may cause timeouts
- Payment not fulfilled (x402) results in 402 response before data is returned
