Example prompt: Who are the top wallets moving USDC on Base right now? I want to see the leaderboard ranked by net flow from the last 10 minutes, and flag which ones are smart wallets, accumulators, or just pass-through routers.

## When to prefer this

Use this endpoint when you need a real-time snapshot of which Base wallets are most actively moving USDC, especially to identify smart money, accumulation patterns, or routing behavior. Ideal for on-chain alpha research, bot detection, or tracking influential wallets on Base in near-real-time.

## Known failure modes

- Stale or unavailable on-chain data may result in empty or partial leaderboard
- Payment of 0.01 USDC required via x402 protocol — missing payment returns 402 error
- Rate limiting or worker timeout may return 5xx errors under high load
- No wallets returned if Base network activity is very low in the time window
