Retrive variable and paramter list with cdsapi or ecmwf.datastores?

Following instructions on ‘ ecmwf-datastores-client — ecmwf.datastores 0.4.0 documentation , I managed to retrieve meta-data concerning datasets (characyerised by their ID) in CDS.

I am now wondering whether there is a function in the ‘cdsapi’ or ‘earthkit/ecmwf.datastores’ modules to retrieve the list of available variables (with variable ID = Name in the API request), as well as parameters used in the ‘request‘ dictionary (e.g. ‘statistics‘, ‘area‘, ‘product_type‘, ‘data_type‘, ‘data_format‘).

Thanks for your help, Christophe
