# AMNOG Knowledge Graph > 2186 assessments, 1415 subgroup ratings (Fragestellungen), structured and searchable. ## About This site provides structured access to IQWiG (Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen) benefit assessments under §35a SGB V (AMNOG). IQWiG assesses the added benefit of new drugs compared to an appropriate comparator therapy (Zweckmäßige Vergleichstherapie / ZVT). The G-BA (Gemeinsamer Bundesausschuss) then makes the final benefit decision. ## Base URL https://iqwig.shoulde.rs ## Machine-readable endpoints GET /api/stats Returns: assessment_count, rated_count, endpoint_count, dispute_count, study_count, rejected_count, rating_distribution (by ausmaß), by_area, by_year, recent GET /api/assessments?area=&ausmaß=&year=&type=&search=&page= Returns: paginated list of assessments with benefit rating summaries Filters: area (therapeutic area), ausmaß (major|considerable|minor|non_quantifiable|none|less), year (YYYY), type (initial|addendum|reassessment) GET /api/assessments/{id} Returns: full assessment with fragestellungen[], endpoint_assessments[], methodological_disputes[], included_studies[], rejected_evidence[], documents[], related[] Example: /api/assessments/A25-160 GET /api/search?q={query}&limit={n} Full-text search across assessment corpus.
