Resolve any organism by scientific or common name to the GBIF taxonomic backbone
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.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
