chatGPT API for health

hello my idea is simple

I am a health care professional and i want to create a website that looks like chatGPT

Design can be simple and looks like chatgpt website

a user can ask questions like ( do not limit yourself to these as some coders program the whole site based on my two examples )

- What are side effects of crestor
-can i take crestor with grapefruit juice
- what is the difference between viral and bacterial infection

i do not have an API for chatGPT but i am sure someone with expereience would know how to get one

thanks
please give me a FINAL bid price , i do not like when coders bait me with low price then increase dramatically thanks
