## How to call it through Zero

```sh
zero fetch --capability predge-wallet-attestation-e325d653
```

Example prompt: Can you get me Predge's signed smart-money attestation for Polymarket wallet 0x8dab6cf42d7e4d1cd6cca897b9e12a8cbe6d69e8 using the 30-day window — I want to see their win rate, rank, and whether they clear the smart money bar?

## When to prefer this

Use this endpoint when you need a verifiable, cryptographically signed credential proving a Polymarket wallet's trading track record — specifically for copy-trading vetting, on-chain reputation proofs, or smart-money signal filtering. Prefer this over generic wallet analytics when you need an offline-verifiable attestation (ed25519 signature) rather than a raw data lookup, or when you need a standardized verdict label like 'verified_smart_money' to gate access or rank traders programmatically.

## Known failure modes

- Wallet address not found or has no resolved Polymarket trades — returns found:false with no attestation payload
- Invalid wallet address format returns a 4xx error
- Window parameter value outside allowed enum (7d/30d) returns a validation error
- Wallet has insufficient trade history to score reliably — may return low conviction score or partial data
- Payment not received or underpaid (x402 protocol) — returns 402 Payment Required

## How this service works

Real-time alerts on whale traders on Polymarket. Heuristic Insider Watch, wallet scoring 0–100, Bloomberg-style web terminal. Free plan included.

## Output

A JSON object containing the wallet's Predge score (0–100), rank among all scored wallets, win rate, verdict label (e.g. 'verified_smart_money'), conviction score, edge lower bound, average entry price, total volume in USD, trade counts, and a fully signed ed25519 attestation payload that can be verified offline using the provided public key and canonical JSON string. Also includes a boolean 'clears_bar' indicating if the wallet meets smart-money thresholds.
