Side effects
- 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
