## When to prefer this

Use this endpoint when you want to test or demonstrate the x402 pay-per-call protocol with a real $0.01 USDC micropayment on Base. Ideal for verifying x402 client implementations, showcasing HTTP monetization to developers, or confirming that a payment-gated API flow works end-to-end.

## Known failure modes

- Payment not included or invalid — server returns HTTP 402 with payment requirements
- Insufficient USDC balance on Base — payment fails before request completes
- Wrong network used (not Base) — payment rejected
- Malformed x402 payment header — request rejected with 400 or 402
