Implement Voiceflow Conversational Interface

Design and implement a basic Voiceflow project that allows a user to query the status of the brand sentiment analysis system. This interface should be able to ask for the current sentiment of a specific brand (e.g., 'What is the sentiment for Product X?'). The Voiceflow agent will need to communicate with your CrewAI system to retrieve real-time data. Outline the necessary API endpoints or data structures your CrewAI system will expose to facilitate this interaction. Provide example Voiceflow intents and responses.
