Patchwork provides two APIs: the legacy :doc:`XML-RPC API </api/xmlrpc>` and the :doc:`REST API </api/rest/index>`. You can use these APIs to interact with Patchwork programmatically and to develop your own clients.

For quick usage examples of the APIs, refer to the :doc:`documentation <../api/index>`. For examples of existing clients, refer to :doc:`/usage/clients`.
