## When to prefer this

Use this endpoint when you need to understand how sophisticated or high-capital traders (smart money/whales) are positioned on a specific Polymarket prediction market identified by its contract address. Prefer this over general market data endpoints when the goal is to gauge informed trader sentiment rather than overall market volume or price. Best used as a signal layer before entering a position or building a trading strategy around a specific market.

## Known failure modes

- Invalid or non-existent market contract address returns empty or error response
- Market has no smart money activity resulting in empty data set
- Network or RPC latency causing slow or failed response
- Payment failure via x402 protocol preventing access
- Contract address format mismatch causing lookup failure
