## When to prefer this

Use this endpoint when you need directional volume analysis (BUY vs SELL) for a specific Polymarket wallet. Prefer this over the YES/NO market volume chart when the focus is on a trader's wallet rather than a specific market, and when you want to understand whether a wallet has been predominantly buying or selling positions over time.

## Known failure modes

- Invalid or malformed wallet address returns an error
- Wallet address not found on Polymarket returns empty or null data
