rredlist is an R client for the IUCN Red List (http://apiv3.iucnredlist.org/api/v3/docs).
The IUCN Red List is a global list of threatened and endangered species.
important note: redlistr is a different package - not working with the IUCN Red List API
See http://apiv3.iucnredlist.org/about
IUCN requires you to get your own API key, an alphanumeric string that you need to send in every request. There's an helper function in the package helping you getting it at http://apiv3.iucnredlist.org/api/v3/token and storing it.
rredlist::rl_use_iucn()Keep this key private. You can pass the key in to each function via the key parameter, but it's better to store the key either as a environment variable (IUCN_REDLIST_KEY) or an R option (iucn_redlist_key) - we recommend using the former option.
High level API
High level functions do the HTTP request and parse data to a data.frame for
ease of downstream use. The high level functions have no underscore on the end
of the function name, e.g., rl_search
Low level API
The parsing to data.frame in the high level API does take extra time. The low
level API only does the HTTP request, and gives back JSON without doing any
more parsing. The low level functions DO have an underscore on the end
of the function name, e.g., rl_search_
This package does not include support for the spatial API, described at http://apiv3.iucnredlist.org/spatial.
From the IUCN folks: "Too many frequent calls, or too many calls per day might get your access blocked temporarily. If you're a heavy API user, the Red List Unit asked that you contact them, as there might be better options. They suggest a 2-second delay between your calls if you plan to make a lot of calls."
