Returns every workspace the authenticated user belongs to, including member workspaces, in one response without pagination, filters, or a specified order. An empty array means the user belongs to no workspaces.

Use a workspace's id to list or retrieve contacts. The role is the API key owner's role in that workspace. Membership alone does not grant contact-list access; the contact endpoints enforce their own permissions, and workspace discovery is only needed when the workspace ID is not already known.

Requires the blinq:identity:read scope.
