A paid sandbox for x402 clients
A paid sandbox for x402 clients. Pay $0.10 and receive your own settled payment back — payer address, amount, network and settlement transaction — so a test can assert your 402, sign, retry and settle loop works against a live facilitator. Scenario parameters exercise the failure paths for free: prove your max-price guard fires, that you abandon an expired quote, handle a rejected payment, and retry a failed settlement.

Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
