Use this endpoint when an AI agent needs a lightweight, no-signup sample of x402 endpoint radar data and can pay $0.008 USDC via x402 micropayment on Solana or Base. Prefer this over full-tier downloads when you want a quick probe (up to 5 items) to evaluate dataset quality before committing to a larger purchase.
