testpayment?price=0.50&scenario=settle_fail

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.
