## 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 x402-wallet-copy-trade-tracker-base-d3abdd86 -d '<json body>'
```

Example prompt: Show me the last 20 token transfers for wallet 0xAbC123...def on Base, labeled as buys or sells, so I can see what this smart-money wallet has been accumulating.

## When to prefer this

Use this endpoint when you need to track and copy-trade a specific wallet on the Base network — it provides labeled buy/sell classification and acquired-token summaries not typically available from raw transaction APIs. Prefer this over generic block explorer APIs when you want pre-labeled, copy-trade-ready output for smart-money following strategies.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Limit exceeds maximum of 40 and is rejected or clamped
- Wallet has no recent activity on Base resulting in an empty list
- Network or RPC issues cause a timeout or partial response
- Non-Base (e.g. Ethereum mainnet) address returns no results

## How this service works

Copy-trade tracker: a wallet's recent token transfers on Base, labeled buy/sell, plus the tokens it just acquired. Send { address, limit? }. Follow smart-money wallets and mirror what they're buying.

## Output

A list of the wallet's recent token transfers on the Base network, each labeled as a buy or sell, along with a summary of the tokens the wallet has recently acquired — useful for copying a smart-money trader's positions.
