Assets are the individual marketing materials (ad copy, images, videos, landing page content, headlines, descriptions) that can be tested and evaluated by AI. This endpoint provides an overview of all creative content in the workspace, enabling users to discover available materials, compare assets across different evaluations, track asset usage, and identify which creative has been tested. Essential for cross-evaluation asset comparison and understanding the complete creative inventory. **When to use:** User wants to see all available creative assets, discover what marketing materials exist, compare the same asset across multiple evaluations, track which creative has been tested, find specific assets by name or type, or get an overview of the workspace's creative inventory. **Common user queries:** - "What assets do we have in the workspace?" - "List all marketing creative materials" - "Show me available ads and copy" - "Which assets have been created?" - "Get all creative assets for comparison" - "List assets by type (images, video, text)" - "Show me the asset inventory" - "What creative materials can I evaluate?" **Returns:** Array of asset objects with metadata (id, name, type, content preview, creation date).
