How can I design a chatbot agent that decides when to use external APIs versus generating responses itself?

Example Concept: Implement a decision tree within your chatbot's logic to evaluate user input and determine the appropriate response path. For instance, if the input requires real-time data (e.g., weather updates), the chatbot should call an external API. Conversely, for general inquiries or conversational responses, the chatbot can generate replies using its internal NLP capabilities. This decision-making process can be managed through conditional statements or a rule-based system integrated into the chatbot's framework.
