How this service works
NCBI Taxonomy lookup by tax id or scientific name - rank, common name, named lineage, genome assembly count, gene counts and child taxa
Output
Returns the taxonomic rank (e.g. species, genus, family), common name, full named lineage array, number of genome assemblies, gene counts, and list of child taxa for the queried organism — sourced from NCBI Taxonomy.
Example use cases
Species classification for research pipeline
“I need full taxonomy info for Canis lupus familiaris — give me its rank, named lineage, common name, gene counts, and genome assembly count from NCBI.”
Identifying child taxa of a genus
“What are the child taxa of the genus Panthera according to NCBI taxonomy? I also want the lineage and rank info.”
Taxon ID resolution for database integration
“I have NCBI taxon ID 9606 — can you resolve it to its scientific name, common name, taxonomic rank, and lineage so I can enrich my species database?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/species/taxonomy/:taxon?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative NCBI-sourced taxonomic classification data including lineage, genome assembly counts, and gene counts for a specific organism identified by scientific name or NCBI taxon ID. Prefer this over general web searches when structured, machine-readable taxonomy data is required for bioinformatics pipelines, database enrichment, or research workflows.
Side effects
- Unknown or misspelled taxon name returns 404 or empty result
- Ambiguous scientific name with multiple matches may return unexpected taxon
- Taxon IDs that are deprecated or merged in NCBI may return no result
- Network timeout or upstream NCBI service unavailability
