Connect OpenAI API to Existing Next.js Project

I have a basic Next.js project and need help connecting the OpenAI API to an existing page. The API key is already available. I just need a simple implementation that sends a prompt and displays the AI response. Requirements: Next.js OpenAI API Basic API integration This is a small task and should take less than an hour for an experienced developer. If everything goes well, I'll have more work available afterward.
