Integrates with the Ontology Lookup Service API to search biomedical ontology terms, retrieve detailed ontology information, explore term hierarchies, and discover semantically similar terms across standardized ontologies like Gene Ontology and Human Phenotype Ontology.
Computed from public signals only — stars, package downloads and how many registries list it. It measures how established a project is, not whether it is safe or right for you.
