# Query platform data with filters

Retrieves platform-level data entries based on filter criteria. Can filter by type, tags (multiple tags are AND-ed), and owner. When filtering by owner, requires Data.Manage permission for that owner. Returns all matching entries not tied to any specific application. Without filters, returns all platform data the user has permission to access.
