## 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 on-chain-wallet-overview-7aed2f30
```

Example prompt: Can you pull up a wallet overview for 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to see the native ETH balance, its USD value, and how many transactions and token transfers it's made?

## When to prefer this

Use this endpoint when you need a quick, high-level on-chain wallet summary — native balance, USD value, tx count, and token-transfer count — for any EVM-compatible address. It is ideal for lightweight due diligence, portfolio snapshots, or activity checks without needing a full blockchain explorer. Prefer this over heavier analytics APIs when you only need aggregate wallet stats rather than full transaction history or token holdings breakdown.

## Known failure modes

- Missing or malformed address parameter returns an error
- Non-checksummed or invalid 0x address may return an error or empty data
- Address with zero activity may return zeroed fields
- Rate limiting or upstream RPC node failures may cause timeouts
- Network unavailability of the Tailscale-hosted endpoint

## How this service works
