## When to prefer this

Use this endpoint when you need to identify the highest-spending participants in the x402 micropayment ecosystem, such as for competitive intelligence, partnership targeting, or ecosystem health monitoring. Prefer this over generic blockchain analytics when you specifically want x402 marketplace buyer behavior.

- 402 Payment Required if USDC payment of $0.05 is not included in the request
