API for proccessing question and give answer with AI Avatar

so I want to input questions to my AI Avatar via API. However, when I read the documentation I didn't find an API to enter my question which was then processed by LLM and then answered using voice by AI Avatar sata. I only found an API to create my AI avatar for drive to speak not one that manages and answers questions.

Question: Does Heygen provide users with questions via API? because the source of my question will come from third party live streaming (Tiktok) and not from user input to Heygen.
