What the probe found
1 of the 26 tools listed anonymously say in their own descriptions that they need an account or a key (run_research), but the endpoint issued no WWW-Authenticate challenge. The requirement is stated only in prose, so a call reaches the tool and comes back as a tool error instead of an authorization step.
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.
The server exposes a public surface before authorization: search_products, create_product, check_balance, credit_history, boost_post, suggest_content_campaign, create_content_campaign, list_content_spaces, write_content_candidates, create_campaign, list_campaigns, get_campaign, run_research, get_research, generate_posts, get_posts, review_posts, regenerate_replies, add_delegate, find_opportunities, submit_participation, find_open_campaigns, get_campaign_brief, submit_campaign_work, get_my_submissions, get_earnings.
