APIAPI for IUCN Red List of Threatened Species Data
Overview
The IUCN API provides access to the Red List of Threatened Species, offering endpoints for species threat status (e.g., Critically Endangered, Vulnerable), habitat details, distribution ranges, and population trends. Responses are in JSON format. Use cases include conservation research, building educational apps about endangered species, integrating wildlife data into environmental monitoring tools, and supporting biodiversity impact assessments for projects. It enables developers to retrieve up-to-date information on over 150,000 species to drive conservation-focused applications.
