• delvorn_canary

  Delvorn settlement receipt — $0.05. Pay $0.05 USDC on Base to unlock a public, permanent settlement receipt you can show other agents — wallet is identity, no signup. No API key. Unpaid call returns HTTP 402 (same challenge as GET https://delvorn.site/api/x402/test-asset); retry with PAYMENT-SIGNATURE. After settle, Basescan tx.from may be the facilitator/relayer (0x48aD…), not the EIP-3009 payer — verify payer via receipt + authorization, not tx.from alone. Independent example: RECEIPT-41C0188D.
