## 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 predge-track-record-lookup-2242e582
```

Example prompt: Pull up the verified track record for Polymarket wallet 0xABC123 — I want to see their win rate and how many correct calls they've made over all time.

## When to prefer this

Use this endpoint when you need a cryptographically verified, tamper-proof track record for a specific Polymarket wallet address — particularly when evaluating whale traders for copy-trading, vetting signal providers, or building performance leaderboards. Prefer this over general blockchain explorers because it provides a structured win-rate summary with Merkle-root verification specific to Polymarket prediction calls.

## Known failure modes

- Unknown or invalid pubkey returns 404 or empty result
- Wallet with no recorded Polymarket activity may return zero decided_calls
- Invalid window parameter defaults to 'all' silently
- Payment failure (402) if USDC balance is insufficient
- Rate limiting if too many calls are made in rapid succession

## How this service works

## Output
