## When to prefer this

Use this endpoint when you need granular, market-level performance data for a specific Polymarket wallet — particularly for analyzing smart money behavior, auditing a trader's track record, or comparing performance across different prediction markets. Prefer this over the general wallet analytics endpoint when you need per-market detail rather than aggregate statistics.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet address not found on Polymarket returns empty or null data
- Network or upstream data provider failure returns 5xx error
- Rate limiting or insufficient USDC payment triggers 402 response
- Address with no Polymarket activity returns empty markets array
