## How to call it through Zero

```sh
zero fetch --capability polymarket-wallet-reputation-api-58c997b4
```

Example prompt: Can you pull the reputation profile for Polymarket wallet 0x1234abcd — I want to know their persona, realized PnL, and how concentrated their positions are to see if they're a sharp or an insider?

## When to prefer this

Use this endpoint when you need to assess the credibility or category of a specific Polymarket wallet — e.g. to determine if it's a sharp, insider, or noise trader before acting on its positions. Prefer this over general blockchain explorers when you need Polymarket-specific persona classification and PnL context rather than raw on-chain transaction data.

## Known failure modes

- Invalid or malformed wallet address returns a 400 or empty response
- Wallet with no Polymarket history may return minimal or null fields
- Payment failure via x402 (insufficient USDC balance on Base) blocks the call
- Rate limiting or quota exhaustion may return a 429
- Data freshness lag of ~24 hours means very recent trades may not be reflected
