## When to prefer this

Use this endpoint when you need to identify which x402 services are genuinely earning the most, with wash trading removed — ideal for competitive research, market analysis, or deciding where to list or invest. Prefer this over raw volume rankings when you need organic-traffic assurance. Use the category filter when you want leaderboard data for a specific vertical like AI, Finance, or Data.

## Known failure modes

- Invalid n value (must be 1–25): returns validation error
- Unknown category string: may return empty result set or error
- Upstream data source unavailable: degraded flag set to true with partial or stale data
- Wash filter removes all results for narrow category: empty top array returned
- Network timeout or provider outage: HTTP error with no data
