What the probe found

No CORS headers for browser-based clients

A cross-origin preflight came back without Access-Control-Allow-Origin, so the endpoint is reachable from native clients only — code running in a web page is stopped by the browser before a request is ever sent.

12 tools usable without signing in

The server exposes a public surface before authorization: quizbase_random, quizbase_list, quizbase_question_by_id, quizbase_stats, quizbase_topics, quizbase_topic_by_slug, quizbase_tags, quizbase_subcategories, quizbase_categories, quizbase_languages, quizbase_regions, quizbase_report.

Depend on this server? Leave an email and get a message when a probe records a change — a tool removed, an argument newly required, an enum narrowed. Alerts are being built; signing up is what tells us to hurry.
