```

Example prompt: Show me the top 10 whale wallets placing bets of at least $500 on the Polymarket market for 'US election 2024' — I want to see their wallet age and whether they're betting yes or no.

## When to prefer this

Use this endpoint when you need to identify large, high-conviction traders on a specific Polymarket prediction market — especially when researching smart money signals, detecting insider-like positioning, or analyzing which wallets are driving price movement on a given question.

## Known failure modes

- Market slug not found — returns empty data or error if the keyword doesn't match any active Polymarket market
- No whales found — market exists but no wallets meet the min_usd threshold
- Invalid query parameters — non-numeric limit or min_usd values return validation errors
- Rate limiting or payment failure — 402 response if USDC payment is not properly attached
- Stale data — real-time tracker may have brief lag during high-volume market events
