## 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 402-com-tr-wallet-summary-186e28f5
```

Example prompt: Can you pull the wallet summary for Base address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e — I want to know how old it is, how many transactions it's made, and when it was last active so I can decide whether to trust it?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.03) summary of a Base wallet's transaction history and age for sybil detection, rug screening, or counterparty trust checks — without needing full transaction details. Prefer this over full on-chain lookups when a lightweight activity profile is sufficient.

## Known failure modes

- Invalid or malformed wallet address returns an error response
- Address not found on Base (zero activity) may return empty or null fields
- Network timeout if Base RPC is slow
- Payment failure (insufficient USDC balance) returns 402 Payment Required
- Rate limiting may occur under high call volume

## How this service works

Wallet age in days, first & last activity timestamps, and outgoing transaction count for any Base address — read straight from the Base archive, not a 30-day feed, so it dates wallets of any age. Counts and last-activity cover what the wallet SENT; inbound transfers don't raise the nonce and aren't counted. Built for sybil screening and counterparty trust checks.

## Output

Returns an object containing the wallet's total transaction count on Base, the timestamp of its first recorded activity, the timestamp of its most recent activity, and the wallet age expressed in days — enabling quick sybil/rug screening or counterparty trust evaluation.
