source: live DNS/TLS/HTTP probes of apis.yml + discovery hosts
tooling: 0-working/probe-domain-security.py, plus a manual per-host HSTS re-probe —
  the script's default user agent is refused by the Cloudflare and AWS ELB edges in
  front of www.crexi.com and api-docs.crexi.com, which suppressed their response headers
  and left hsts null
hosts:
- host: www.crexi.com
  https: true
  tls_version: TLSv1.3
  cert_expires: Sep  6 18:50:38 2026 GMT
  hsts: false
  note: Every request is answered with an HTTP 403 Cloudflare bot-management interstitial
    unless the client solves the challenge; no Strict-Transport-Security header is
    returned on that response.
- host: api.crexi.com
  https: true
  tls_version: TLSv1.3
  cert_expires: Sep  6 18:50:38 2026 GMT
  hsts: false
  note: 301 to index.html then 200; no Strict-Transport-Security header on either response.
    /health also returns 200 without HSTS.

  hsts_note: Neither the marketplace host (www.crexi.com) nor either API host (api.crexi.com,
    exchange.crexi.com) sets Strict-Transport-Security. HSTS is present only on the
    three third-party-hosted properties — the Theneo docs portal, the HubSpot help
    centre and the Atlassian status page.
