IUCN Red List API

The Red List API has been recently upgraded to offer more methods for querying the Red List data. Please make sure to use the correct methods for what you need.

The IUCN Red List version is 2021-3.

You will also need a token before being able to use the API.

Please note that there will be a longer than normal delay in processing API requests during this end of year period, until first weeks of January 2022
