Story

In the future, and that's why this story has a lower priority, we want to add filters to our Marketplace UI.

For that, the MarketplaceAPI should support pagination, sorting, and filters.

Of course, all implementations should be updated.

MarketplaceClient if RHIDP-5321 isn't done yet, or MarketplaceBackendClient and MarketplaceCatalogClient if it's done. Whatever is done first is fine.

The default pagination (50?) and sorting (name?) should be documented.

Background
