  Marketing/docs hosts (abstractapi.com, www.abstractapi.com) sit behind
  Cloudflare on TLSv1.3 with HSTS. The API host
  (phonevalidation.abstractapi.com) is served directly by nginx/1.18.0 on
  TLSv1.2 with HSTS (includeSubDomains), X-Frame-Options DENY,
  X-Content-Type-Options nosniff, and a restrictive Allow of GET, HEAD, OPTIONS.
  No CAA records, no SPF record, and DMARC is present only at p=none; DNSSEC is
  not enabled on abstractapi.com. Probed live 2026-07-12.
