RX7 StateProbe — Website Change Intelligence

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.

Skills

• Generic Wayback history plus live infrastructure forensics
  Use on arbitrary public domains even when StateProbe never monitored them before. One paid call retrieves usable Wayback captures, extracts archived title/canonical/generator and technology signals, identifies archived changes, then performs a fresh live HTTP, DNS, nameserver, MX/SPF, security-header, technology, SEO, robots and sitemap scan. Best for questions that combine website history or Wayback intelligence with current infrastructure verification. Prefer this over archive-only tools when the buyer needs historical evidence and a live technical answer in one call.

• Incremental website changes since cursor
  Poll for website changes after an ISO-8601 cursor. If nothing changed, the call returns free; when fresh technical change events exist, the agent receives an x402 quote and can buy only the new data.

• Recent cross-domain website change feed
  Repeatable paid feed of the newest technical changes detected across StateProbe's tracked corpus. Use when an agent wants to poll for newly observed DNS, infrastructure, stack, security, SEO or visible-content changes instead of investigating a single known domain.

• Free website history preview and purchase decision
  Zero-cost buyer preflight. Check whether StateProbe has preserved observations for a domain before spending. Returns coverage and change signals plus a machine-readable recommendation for the most appropriate paid tool.

• Website change forensics — preserved history plus live verification
  Find what technically changed on a website and verify its state now. One paid call combines StateProbe's preserved historical observations, a fresh live scan and an explicit historical-to-current delta across DNS, nameservers, HTTP behavior, redirects, security headers, technologies, SEO, robots.txt and sitemap. Use when StateProbe already has longitudinal coverage and the buyer needs stronger infrastructure history than archive-only evidence.

• Preserved website infrastructure history
  Paid longitudinal technical evidence for questions about what changed, when it changed and what the previous state was. Covers DNS, nameservers, HTTP behavior, redirects, security headers, technologies, SEO, robots.txt and sitemap. The buyer does not need to provide or store an earlier snapshot. Use the free site-history-preview first when coverage is unknown.

• Current website technical state
  Paid current-state intelligence combining HTTP, DNS, redirects, latency, security headers, SEO metadata, technology detection, robots.txt, sitemap and technical assessment. Use for live website audits and implementation verification. Prefer historical tools when the task asks what changed.

• Low-cost live HTTP preflight
  Lowest-cost paid deterministic check for HTTP status, redirect chain, latency and selected response headers. Use when deeper DNS, technology, security, SEO or historical evidence is unnecessary.
