Example prompt: What are the top 10 largest whale trades on Polymarket right now — I want to see where the big money is moving across tracked whale wallets.

## When to prefer this

Use this endpoint when you need a quick, agent-ready snapshot of where large Polymarket participants are placing significant bets — ideal for front-running analysis, sentiment gauging, or augmenting prediction market trading decisions with smart-money flow. Prefer this over generic Polymarket scans when the specific focus is on whale wallet behavior and size-ranked trade history.

## Known failure modes

- No recent whale activity detected — returns empty or minimal list if tracked wallets have been inactive
- Payment failure (402) if the x402 USDC micropayment of $0.003 is not properly submitted
- Upstream Polymarket data unavailability causing stale or incomplete results
- Rate limiting or authentication errors if called too frequently without valid credentials

## How this service works

## Output
