Use LLM to create entities via the API

Hi, community. I’m a newbie in all these LLM things and need your advice. Is it suitable to use chat GPT function calling functionality to create entities via REST API?

The flow:
I have an API that creates some entities, I want to move this functionality into the chat. The LLM’s responsibility will be to collect information from the user and provide JSON as the input to the function. The function will call REST API POST request to create an entity. Is this a good case for LLM, cause all examples I saw before use API or database as source of data and don’t create anything?

Thank you and happy learning)
