Some of the following Parliamentary APIs are versioned. Versioned APIs can be distinguished from others by the "/api/v{x}" portion of the URL, x being the version number. A version of an API endpoint can have parts of its inputs or outputs extended, but not removed or modified. If an endpoint requires input or output modifications or removal, this would result in a new version.
