The Monarch Initiative provides a biomedical knowledge graph and related tools for exploring relationships among diseases, genes, phenotypes, cases, and other biological entities. Its website and APIs support retrieval, search, semantic similarity, and annotation over integrated life-science data.
Monarch Initiative exposes two public HTTP APIs: the current Monarch API v3 and the legacy BioLink API; both appear publicly accessible without authentication.
