#species

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 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.

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.
