method: probed
source: live probes of mediacaption.io, www.mediacaption.io, api.mediacaption.io and clerk.mediacaption.io
note: The bare domain 307-redirects every path to www; www and api 404 every /.well-known/ document and
  /llms.txt (the 404s return the site's HTML shell). The one real hit is the OpenID Connect discovery
  document served by the provider's Clerk tenant at clerk.mediacaption.io — it governs web-app sign-in,
  not the public API, which authenticates with mc_live_ API keys (see authentication/). No security.txt,
  api-catalog, ai-plugin, agent card, or llms.txt is served on any host.
