Use this endpoint when you need to identify the largest position holders in a specific Polymarket prediction market by its contract address. Ideal for whale-watching, market sentiment analysis, or understanding concentration risk in a specific prediction market. Prefer this over general wallet analytics endpoints when the goal is market-specific holder ranking rather than per-wallet portfolio analysis.

- Invalid or non-existent market address returns empty or error response
- Market has no holders yet — returns empty data set
- Payment failure (x402) if USDC not provided — returns 402 Payment Required
- Network timeout or upstream Polymarket data unavailability
