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.
