Core10 Domain Security

generated: '2026-08-11'
method: probed
source: live DNS/TLS/HTTP probes of every Core10-lineage host
note: >-
  Core10's own domain, core10.io, still holds a valid certificate and 301-redirects to
  monarchfts.com. api.getaccrue.com is the only live API host in the lineage; it is the
  weakest posture here — TLSv1.2 and no HSTS header at all — and it serves a bare nginx 404
  on every path, so nothing about the contract behind it is public.
