Match scientific or common species names to the GBIF taxonomic backbone (kingdom to species), search the global species catalogue, fetch full taxon records with vernacular names, and retrieve geo-located occurrence observations. Ideal for nature, education, research, conservation and citizen-science apps.

IUCN Red List API

The conservation status of assessed species from the IUCN Red List as an API — the reference a wildlife, conservation, education or research application needs. For each of 150,000+ assessed species the API returns its scientific name, common name, taxonomy (kingdom, class, family), the IUCN Red List category (CR critically endangered, EN endangered, VU vulnerable, NT near threatened, LC least concern, DD data deficient, EW extinct in the wild, EX extinct) and the IUCN taxon id. Look a species up by scientific name, search by scientific or common name, list every species in a Red List category (e.g. all critically endangered) or in a taxonomic class (e.g. all assessed mammals), and read a full category breakdown. Distinct from worms-api (the marine-species taxonomy register) — this is the conservation-status reference. Served from memory — always fast.

iNaturalist API

iNaturalist as an API — the world's largest citizen-science nature platform, returned as clean JSON, no key. Search hundreds of millions of wildlife observations by species name, place or quality grade and get each one with its photos, identified species, location, date and observer. Open a single observation, search taxa (species) and open a taxon for its common name, rank, full ancestry, photos, Wikipedia link, conservation status and observation count. Discover the most-observed species in any place (by place id or latitude/longitude), autocomplete places, and rank the top observers. Live data straight from iNaturalist. Distinct from taxonomic registries: this is real community observations with photos and locations — ideal for nature, birding and species-identification apps, biodiversity dashboards and education. 7 data endpoints. Authenticated with an x-oanor-key; fair-use rate limits per plan.

WoRMS Marine Species API

The World Register of Marine Species (WoRMS) as an API — the authoritative, expert-curated taxonomic register of the world's marine life, maintained by a global network of taxonomists. WoRMS provides the accepted scientific names, naming authorities, taxonomic status and synonymy, full classification and vernacular (common) names for marine species. /v1/search?name=Orcinus orca searches species by scientific name (set fuzzy=true for partial matching, marine_only=true to restrict to marine taxa), returning each match's AphiaID (WoRMS' stable identifier), accepted name, authority, rank, taxonomic status, valid name and higher classification. /v1/species?id=137102 returns a species' full record by AphiaID — name and authority, status, the kingdom-to-genus classification, marine and brackish flags, and citation. /v1/classification?id=137102 returns the complete taxonomic tree from Biota down to the taxon, rank by rank. /v1/vernaculars?id=137102 returns the common names with their language. Get an AphiaID from /v1/search, then look up its details, tree or common names. Ideal for marine biology, fisheries science, ecology, aquaculture and biodiversity-data harmonisation. Data from WoRMS (CC BY). This is authoritative marine taxonomy and nomenclature — distinct from species-occurrence/biodiversity databases (such as GBIF) and from sequence or genome databases.

Open Tree of Life API

The tree of life as an API — powered by the Open Tree of Life, the project that unifies published phylogenetic trees and taxonomies into a single synthetic tree spanning about 2.3 million named species. Resolve any scientific name to its canonical taxon and Open Tree Taxonomy (OTT) id (cross-referenced to NCBI, GBIF and other sources); read a taxon's classification and full lineage of ancestors up the tree (genus, family, order, class, …); and compute the most recent common ancestor (MRCA) of any set of species — the heart of comparative biology and "how related are these organisms?" questions. From Homo sapiens and the great apes to any branch of plants, fungi, animals and microbes, it is ideal for biology, evolution, ecology, education and bioinformatics tools. An evolutionary-tree / phylogenetics reference — distinct from species-occurrence data (biodiversity / GBIF), marine taxonomy (WoRMS) and sequence databases. Open data from the Open Tree of Life project (CC0).
