    def artifact_versions(self, type_name, name, per_page=50):
        """Deprecated, use artifacts(type_name, name) instead."""
        deprecate(

                "use Api.artifacts(type_name, name) instead."
            ),
        )
        return self.artifacts(type_name, name, per_page=per_page)
