This bit of code generated by chatgpt gives me: Request failed: BadRequest

API

Hi, I’m not a skilled programmer. I’m trying to make a C# app with visual studio and windows forms using chatgpt. I asked chatgpt to make me some basic code to try it out. I get an error: Request failed: BadRequest. How can I figure out what the problem is?

using System;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace YourNamespace
{
    public partial class Form1 : Form
    {
        private const string ApiKey = "your-api-key";
        private const string ApiUrl = "https://api.openai.com/v1/completions";

        public Form1()
        {
            InitializeComponent();
        }

        private async void generateButton_Click(object sender, EventArgs e)
        {
            string prompt = promptTextBox.Text;
            string response = await GenerateText(prompt);
            responseTextBox.Text = response;
        }

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

                var requestBody = new
                {
                    prompt = prompt,
                    max_tokens = 50 // Adjust as needed
                };

                var requestContent = new StringContent(Newtonsoft.Json.JsonConvert.SerializeObject(requestBody), Encoding.UTF8, "application/json");

                var response = await client.PostAsync(ApiUrl, requestContent);

                if (response.IsSuccessStatusCode)
                {
                    string responseContent = await response.Content.ReadAsStringAsync();
                    return responseContent;
                }
                else
                {
                    return $"Request failed: {response.StatusCode}";
                }
            }
        }
    }
}
