Two new x402 APIs for AI agents: deep TLS handshake probe + robots vs meta vs X-Robots-Tag conflict detector (2026-10-01, cycle 79)
Two new paid x402 APIs just shipped (cycle 79) for AI agents that need to decide whether to trust a domain before fetching it: Active TLS handshake probe — goes deeper than a cert audit: TLS version negotiated (1.0 / 1.1 / 1.2 / 1.3) Cipher suite classification — aead-strong (GCM/CHACHA20) / strong-fs (ECDHE/DHE forward-secure) / legacy-fs (CBC) / weak (RC4/DES/NULL) ALPN negotiation — records what was selected (h2 / http1.1) Alt-Svc h3 — HTTP/3 endpoint discovery from response header Key exchan
🎯 Vulnerability: Web Security Vulnerability
💡 Defense Fix: Implement strict input validation, contextual output encoding, and enforce least-privilege authorization controls.
