## How to call it through Zero

```sh
zero fetch --capability agenttools-ethereum-base-wallet-snapshot-07afd0b0
```

Example prompt: Can you pull the on-chain profile for Ethereum wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to see its balance, recent activity, top tokens, and who it transacts with most often?

## When to prefer this

Choose this endpoint when you need a high-level, interpreted on-chain identity summary for an Ethereum or Base wallet in a single call — rather than stitching together raw RPC calls for balance, transactions, and token data separately. It is ideal for due diligence, fraud screening, counterparty research, or any scenario where the question is 'who is this address?' rather than requiring raw block-level data. Prefer this over generic block explorers when you need structured, agent-consumable output with derived signals like fresh-wallet and high-volume flags.

## Known failure modes

- Invalid or malformed wallet address returns an error or empty result
- Unsupported chain value (not 'ethereum' or 'base') returns a validation error
- Address with zero on-chain activity may return minimal data with empty token/counterparty arrays
- Blockscout API downtime or rate limiting may cause timeouts or 5xx errors
- ENS names or non-checksummed addresses may not resolve correctly

## How this service works

One-call on-chain profile of any Ethereum or Base wallet via Blockscout: native balance, transaction and transfer counts, activity recency, top token holdings, and most frequent recent counterparties — with fresh-wallet and high-volume flags. The 'who is this address?' conclusion, not raw RPC data. Use this when an agent needs to on-chain wallet profile: balance, activity, tokens, counterparties.

## Output

A structured on-chain summary including native token balance, total transaction and transfer counts, timestamp of most recent activity, top token holdings with amounts, the most frequent recent counterparty addresses, and boolean flags indicating whether the wallet is newly created (fresh-wallet) or unusually high-volume.
