Tree of Life Web Services

The Tree of Life offers the following web services for developers:

 ToL Group ID Service
This service returns information about taxon names and ToL identifiers. You will need ToL ids in order to specify the branches of the tree for which you want to download data.
 ToL Tree Structure Services
This service returns the tree structure for a given branch of the tree, along with group names and properties of groups.
 ToL Page Content Services
This service returns the content (text) of ToL branch and leaf pages.
 ToL Media Services
This service returns media files from the ToL collection.

In order to use the ToL web services, you will need a User Key. Please also see the Terms of Use.

Please note that the Tree of Life web services are still very much under construction. The current implementation is preliminary, and you should not rely on the services being available in perpetuity in their current form. We expect to add new features and to modify the format of the response documents over the next few months. If you have ideas on how the services could be improved, please send us your feedback!
