ApiKey usage #2: many users with different apiKey

This example demonstrates, how to use the Forge.OpenAI without dependency injection and create service instances for individual users which have different OpenAI API key.

static async Task Main(string[] args)
{
    // This example demonstrates, how to use the Forge.OpenAI without dependency injection
    // and create service instances for individual users which have different OpenAI API key.

    // The very first step to create an account at OpenAI: https://platform.openai.com/
    // Using the loggedIn account, navigate to https://platform.openai.com/account/api-keys
    // Here you can create apiKey(s), for example let's create two for this demo.

    // Add the created API keys here
    const string apiKeyForUserA = "";
    const string apiKeyForUserB = "";

    OpenAIOptions optionsForUserA = new OpenAIOptions();
    optionsForUserA.AuthenticationInfo = new AuthenticationInfo(apiKeyForUserA);

    OpenAIOptions optionsForUserB = new OpenAIOptions();
    optionsForUserB.AuthenticationInfo = new AuthenticationInfo(apiKeyForUserB);

    IOpenAIService openAiInstanceForUserA = OpenAIService.CreateService(optionsForUserA);
    IOpenAIService openAiInstanceForUserB = OpenAIService.CreateService(optionsForUserB);

    await TextEditExampleAsync(openAiInstanceForUserA);
    await TextEditExampleAsync(openAiInstanceForUserB);

    // NOTE: there is an other example in the Playgrouns here, which demonstrates
    // how you can use the OpenAPI with multiple users, but with only one ApiKey
    // This is useful, if you have multiple users, becuase it is highly recommended
    // to differentiate them. If a user against the OpenAPI rules, this user will be
    // denied and not your whole apiKey and your other users.
}

static async Task TextEditExampleAsync(IOpenAIService openAIService)
{
    TextEditRequest request = new TextEditRequest();
    request.InputTextForEditing = "Do you happy with your order?";
    request.Instruction = "Fix the grammar";

    Console.WriteLine(request.InputTextForEditing);
    Console.WriteLine(request.Instruction);

    HttpOperationResult<TextEditResponse> response = 
        await openAIService.TextEditService
            .GetAsync(request, CancellationToken.None)
                .ConfigureAwait(false);
            
    if (response.IsSuccess)
    {
        // output: Are you happy with your order?
        response.Result!.Choices.ForEach(c => Console.WriteLine(c.Text));
    }
    else
    {
        Console.WriteLine(response);
    }
