.NET Core API using ChatGPT completions

One of the latest technologies that are gaining popularity in this field is the ChatGPT API. In this tutorial, we will learn how to build a supercharged .NET Core Web API that leverages the power of ChatGPT.

We will be using .NET Core and Visual Studio to create our web API project. Once we have our development environment set up, we can proceed to the next step.

Accessing the ChatGPT API

The easiest way to access the ChatGPT Api right now using .NET is probably HttpClient. I’ve tried some of the existing libs, but they aren’t complete enough or don’t yet offer the whole functionality.

Getting API Key: To use the ChatGPT API, we need to register for an API key. Go to the ChatGPT website and follow the instructions to register for an account. Once you have registered, you will receive an API key that you can use to access the API.

Adding Dependencies: To use HttpClient, you need to add the following package to your project:

<PackageReference Include="Microsoft.AspNet.WebApi.Client" Version="5.2.9" />

Now we can use HttpClient to send a POST request to the API with the necessary data. Here’s an example:

using System.Net.Http;
using System.Net.Http.Headers;
using System.Text.Json;
using System.Threading.Tasks;

namespace YourNamespace
{
    public class ChatGPTClient
    {
        private readonly HttpClient _httpClient;
        private readonly string…
