## 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 wallet-head-to-head-comparison-smart-money-profile-7c1461fd
```

Example prompt: Compare these two wallets for copy trading — 0x1234abcd... vs 0x5678efgh... on Base — and tell me which one has better realized profit, ROI, and overall smart-money score so I know which to follow.

## When to prefer this

Use this endpoint when you have exactly two wallet candidates and need a direct, computed judgment on which is the smarter trader — ideal for copy-trading decisions, trust scoring, or vetting referrals. Prefer this over single-wallet analysis endpoints when a relative ranking between two addresses is the goal.

## Known failure modes

- Invalid or malformed wallet addresses return an error
- Wallets with no on-chain trading history may produce null or zero scores
- Unsupported chain identifiers result in an error response
- Rate limiting or payment failure returns a 402 or 429 error
- Network timeouts if on-chain data indexing is slow

## How this service works

Head-to-head comparison of two wallets' smart-money profiles - realized profit, ROI, trading volume and a composite score each, with a clear winner - lets agents decide which wallet to copy-trade or trust when choosing between candidates, a computed judgment across both. wallet compare, compare wallets, which wallet is better, copy trade comparison, smart money compare, better trader, wallet vs wallet

## Output

A structured head-to-head report for both wallets including each one's realized profit, ROI, trading volume, and a composite smart-money score, plus an explicit winner declaration indicating which wallet is the stronger copy-trade or trust candidate.
