Pay with Base USDC, paste the tx hash, get the audit JSON.

This is the non-x402 checkout for humans and wallet-native agents. Send 0.25 USDC on Base to Devryno, then use the transaction hash as your receipt for one Merchant Feed Audit.

1. Send payment

  3. Amount: 0.25 USDC
  4. Recipient: 0xdD1729943bf7C408456cef52886ad12B05B57dC2

One transaction hash unlocks one report. Do not overpay; extra USDC is not tracked as a credit yet.
