CertBeforePay is a pay-per-check API for AI agents. Before an agent pays a wallet, loads a skill or MCP server, or trusts a peer, it can call CertBeforePay over x402 (USDC on Base, no account). Routes include a wallet check against the ScamSniffer scam/phishing list, an OWASP-mapped self-check, a skill/MCP gate, and a short-lived signed Agent Trust Certificate of the scan result. The certificate is not a legal CA or PKI. The wallet check is a scam/phishing signal, not an OFAC/sanctions screen.
