# API reference

Where you look things up. The Python API pages are generated from the API's source at v0.9.1: the
signature and the docstring of every public method of `RobotClient`, the tool methods, the registered tools, the
error codes, the environment variables and the controller's options, with notes written around them. The build
fails when a page names a method the API no longer has, and the tests fail when a method is on no page.
