Taxonomy lookup for resolving a common or scientific organism name into its NCBI TaxID, rank, and full ancestor lineage. Backed by NCBI E-utilities against the taxonomy database, so results match what researchers get from NCBI directly: species classification, genus/family/order chain, and each ancestor's own rank and TaxID. Organism lineage, species classification, ncbi taxid resolver, taxonomic hierarchy search. Use it as a taxonomy lookup API, an organism lineage resolver, or a species classification tool for biology, bioinformatics, and research agents.
