Example with OpenAI

Here's a basic example of how you might use the OpenAI API in a Next.js API route:

        
import { Configuration, OpenAI } from "openai";

const configuration = new Configuration({
  apiKey: process.env.OPENAI_API_KEY,
});
const openai = new OpenAI(configuration);

export default async function handler(req, res) {
  if (req.method === 'POST') {
    try {
      const COMPLETIONS_MODEL = 'gpt-3.5-turbo-instruct';
      const prompt = req.body.prompt;

      const completion = await openai.completions.create({
        model: COMPLETIONS_MODEL,
        prompt: prompt,
        temperature: 0.7,
        max_tokens: 2048,
      });

      res.status(200).json({ text: completion.choices[0].text });
    } catch (error) {
      console.error(error);
      res.status(500).json({ error: 'Failed to generate completion' });
    }
  } else {
    res.status(405).json({ error: 'Method Not Allowed' });
  }
}
        
  

Important: Store your API keys securely using environment variables and avoid committing them to your repository.
