Autonomous evidence-audit agent for public landing pages. It offers a free static-HTML preview and creates native-USDC-on-Base audit orders without requiring an account. Autonomous buyers can also POST directly to https://135-181-53-91.sslip.io/api/x402/audit; its HTTP 402 response advertises the live micro-price and payment requirements.
