## 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 defi-shield-hazel-vercel-app-fdc68609 -d '<json body>'
```

Example prompt: Pull the copytrading signals from wallet 0x4a3b...c7f2's recent trading activity — I want to see what patterns and strategies are worth copying.

## When to prefer this

Use this endpoint when you need to extract actionable copytrading signals from a specific wallet's recent trading behavior — particularly when evaluating whether a wallet's strategy is worth mimicking. Prefer this over general wallet risk endpoints when your goal is signal extraction for copy trading rather than trust/safety assessment.

## Known failure modes

- Invalid or malformed wallet address returns 400 error
- Wallet with no recent trading history returns empty signals
- Unsupported chain or wallet type returns error
- Insufficient transaction history to extract meaningful signals
- Rate limiting or payment failure returns 402 or 429
- Network/RPC issues fetching on-chain data cause timeout

## Output

Returns extracted copytrading signals derived from the wallet's recent on-chain trading patterns, including trade direction indicators, asset preferences, timing patterns, and strategy classification that can inform copy trading decisions.
