create a program that uses openai codex to generate code from text in csharp

main.cs
using System;
using System.Net.Http;
using System.Text.Json;
using System.Threading.Tasks;

public class CodexClient
{
    private readonly string apiKey;
    private readonly string codexEndpoint = "https://api.openai.com/v1/codex:generate";

    public CodexClient(string apiKey)
    {
        this.apiKey = apiKey;
    }

    public async Task<string> GenerateCode(string prompt)
    {
        using (var client = new HttpClient())
        {
            client.DefaultRequestHeaders.Add("Authorization", $"Bearer {apiKey}");

            var requestBody = new
            {
                prompt = $"language=csharp\n{prompt}",
            };

            var response = await client.PostAsync(codexEndpoint, new StringContent(JsonSerializer.Serialize(requestBody)));
            var content = await response.Content.ReadAsStringAsync();

            if (!response.IsSuccessStatusCode)
            {
                // handle error
            }
            else
            {
                // parse content for generated code
                return content;
            }
        }
