mirrored listing x402 eip155:8453base

Decodes YOUR signed EIP-3009 authorization and hands it back field by field — payer, value

Decodes YOUR signed EIP-3009 authorization and hands it back field by field — payer, value, recipient, validity window, nonce — so you can see exactly what the server received. Signing bugs are miserable to debug because the only feedback is usually "invalid"; this shows you which field is wrong. Free simulated failure cases live at https://soren.com/v1/conformance
