BaseClient#

class sunpy.net.base_client.BaseClient[source]#

Bases: ABC

This defines the Abstract Base Class for each download client.

The BaseClient has several abstract methods that ensure that any subclass enforces the bare minimum API. These are search, fetch and _can_handle_query. The last one ensures that each download client can be registered with Fido.

Most download clients should subclass GenericClient. If the structure of GenericClient is not useful you should use BaseClient. VSOClient and JSOCClient are examples of download clients that subclass BaseClient.
