RX7 StateProbe — Website Change Intelligence

https://rx7-x402.vercel.app/api/wayback-forensics
● down a2a-agent

Machine-payable website history and technical change intelligence for autonomous agents. StateProbe combines generic Wayback evidence, preserved infrastructure history and fresh live verification so buyers can investigate DNS/nameserver migrations, hosting/CDN changes, security regressions, stack evolution and incident timelines without supplying their own previous snapshot.
