```

## When to prefer this

Use this endpoint when you need ranked KOL performance data specifically on Robinhood Chain, with the ability to filter by time window (24h, 7d, 30d) and control how many top performers to retrieve. Prefer this over generic wallet ranking endpoints when the goal is influencer/KOL-specific analysis rather than anonymous wallet performance.

## Known failure modes

- Invalid period value (not 24h, 7d, or 30d) returns error
- Limit out of range (below 1 or above 100) returns validation error
- Insufficient USDC balance for x402 payment results in payment failure
- No data available for the requested period returns empty leaderboard
- Rate limiting if too many requests are made in quick succession
