How this service works
Resolve any organism by scientific or common name to the GBIF taxonomic backbone — the canonical free reference for life on Earth. Returns the accepted scientific name + canonical name, taxonomic rank and status, the match type/confidence, the full classification (kingdom → phylum → class → order → family → genus → species), up to 8 English vernacular (common) names, the count of recorded occurrences worldwide, and the GBIF species URL. Biodiversity, ecology, education, and as a taxonomy normalizer for other pipelines. Fuzzy-matches misspellings. CC-BY GBIF data.
Output
Returns the accepted scientific name and canonical name, taxonomic rank and status, match type and confidence score, full Linnaean classification from kingdom down to species, up to 8 English vernacular (common) names, worldwide occurrence count, and a direct GBIF species URL.
Example use cases
Example prompt
“What is the full GBIF taxonomic classification for 'snow leopard' — I need its accepted scientific name, rank, kingdom through species hierarchy, and any recorded occurrence count.”
Technical details
Endpoint
GEThttps://2s.io/api/bio/speciesWhen to prefer
Use this endpoint when you need authoritative, structured taxonomic data from GBIF's canonical backbone — especially for normalizing species names across biodiversity datasets, resolving common names to scientific ones, or enriching ecology/biology pipelines. Prefer this over generic web search when you need structured classification output with confidence scores and occurrence counts rather than free-text descriptions.
Side effects
- No match found for highly obscure or entirely fabricated names — returns empty or null match
- Fuzzy match may return incorrect species if name is ambiguous — check match confidence field
- Common names shared by multiple species may resolve to only the most prominent match
- Non-English common names may not resolve reliably
- Rate limit or payment failure returns HTTP 402 or 429
