GleanMark Trademark Search

1 of the 61 tools listed anonymously say in their own descriptions that they need an account or a key (resolve_trademark_subject), 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: analyze_prosecution_history, analyze_ttab_proceeding, check_brand_availability, check_domain_availability, compare_marks, count_trademarks_by_attributes, get_class_relationships, get_cohort_event_intervals, get_correspondent_marks, get_correspondent_specialization, get_deadline_satisfaction_mapping, get_event_code_reference, get_event_status_mapping, get_fame_profile, get_firm_correspondent_tasks, get_firm_deadlines, get_firm_oa_outcomes, get_firm_top_correspondents, get_latest_office_action, get_mark_ai_summary, get_mark_deadlines, get_mark_international_profile, get_mark_owner_landscape, get_mark_prosecution_summary, get_nice_classes, get_owner_ai_summary, get_owner_deadlines, get_owner_filing_trends, get_owner_goods_keywords, get_owner_related_parties, get_owner_ttab_enforcement, get_owner_ttab_stats, get_prosecution_document, get_prosecution_timeline, get_reference_lookup, get_similar_marks, get_top_filers, get_trademark_analytics, get_ttab_document, get_ttab_proceeding_details, is_mark_famous, list_prosecution_documents, lookup_trademark, phonetic_search, recommend_nice_classes, research_office_action, resolve_trademark_subject, run_dupont_analysis, run_knockout_search, run_safe_analytics, search_attorneys, search_by_owner, search_claimed_colors, search_design_codes, search_goods_services, search_mark_statements, search_trademarks, search_ttab_proceedings, suggest_gs_descriptions, validate_gs_description, web_research.
