## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability base-defi-snapshot-balance-protocol-data-78c2c25a
```

Example prompt: Can you pull the current token balances, gas price, and DeFi protocol TVL and APY for my Base wallet 0xAbC123...?

## When to prefer this

Use this endpoint when you need a quick, paid on-demand snapshot of a Base network EVM address's token balances and DeFi protocol metrics (TVL/APY) without running your own RPC node. Prefer this over generic Ethereum endpoints specifically for Base L2 chain data.

## Known failure modes

- Invalid or malformed EVM address returns an error response
- Address with no activity may return empty balances
- Base network RPC outage may cause stale or missing data
- Missing required 'address' parameter returns 400-level error
- Unrecognized contract addresses may not resolve protocol metadata
