taxize-package: Taxonomic Information from Around the Web

Description About Currently supported APIs Catalogue of Life (COL) Author(s)


This package interacts with a suite of web 'APIs' for taxonomic tasks, such as verifying species names, getting taxonomic hierarchies, and verifying name spelling.


Allows users to search over many websites for species names (scientific and common) and download up- and downstream taxonomic hierarchical information - and many other things.

The functions in the package that hit a specific API have a prefix and suffix separated by an underscore. They follow the format of service_whatitdoes. For example, gnr_resolve uses the Global Names Resolver API to resolve species names.

General functions in the package that don't hit a specific API don't have two words separated by an underscore, e.g., classification

You need API keys for some data sources. See taxize-authentication for more information.

Catalogue of Life (COL)

COL introduced rate limiting recently in 2019 - which has made the API essentially unusable - CoL+ is coming soon and we'll incorporate it here when it's stable. See for the R implementation for CoL+
