The code shows you how to fetch a data from OpenAI

openai.ts

const fetchOpenAI = async (text: string) => {
  const response = await fetch('https://api.openai.com/v1/completions', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      Authorization: `Bearer ${Deno.env.get('OPENAI_KEY')}`,
    },
    body: JSON.stringify({
      model: 'text-davinci-003',
      prompt: text,
      max_tokens: 4000,
    }),
  });
  return response.json();
};

(async () => {
  const response = await fetchOpenAI('Who was the first president of Uzbekistan?');

  console.log(response.choices[0].text);
})();
