This is the simplest example of using Chilkat with Azure AI Foundry.

Note: This example requires Chilkat v11.3.0 or greater.

BOOL success = NO;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

CkoAi *ai = [[CkoAi alloc] init];

// Before running the code, ensure the following prerequisites for App Registration in Microsoft Entra ID for Azure AI Foundry:
// 1. Register an app for Azure AI Foundry.
// 2. Assign an IAM Role to the resource to enable OAuth2 Client-Credentials for calling Azure AI Foundry.

// For Azure AI Foundry we use "custom".
ai.Provider = @"custom";

// The base URL format for the Chat Completions API when using the cognitiveservices.azure.com domain is:
// https://{resource-name}.cognitiveservices.azure.com/openai/deployments/{deployment-id}/chat/completions?api-version={api-version}

// The string "{deployment}" in the base URL is dynamically replaced with the selected AI model each time a request is sent.
// In this case, the chosen model (below) is "gpt-4o".  After substitution the base URL becomes: 
// https://chilkat.cognitiveservices.azure.com/openai/deployments/gpt-4o/chat/completions?api-version=2025-01-01-preview

// In this example, our resource name is "chilkat", and the api-version is "2025-01-01-preview"
ai.BaseUrl = @"https://chilkat.cognitiveservices.azure.com/openai/deployments/{deployment}/chat/completions?api-version=2025-01-01-preview";
ai.ApiSpec = @"ChatCompletions";

// Use your provider's API key.
ai.ApiKey = @"MY_API_KEY";

// Set Azure Foundry specific params.
CkoJsonObject *azureParams = [[CkoJsonObject alloc] init];

// The tenant ID is a GUID such as 17280f2d-f709-4a7b-af1d-9928190e13cf
[azureParams UpdateString: @"azure.tenantId" value: @"TENANT_ID"];

// The client ID is a GUID such as 4abd4bf6-5260-4795-90f6-1e91ce4f582c
[azureParams UpdateString: @"azure.clientId" value: @"CLIENT_ID"];

// Such as UZc8Q~YBrRIgfe_zbAOwWV.8ikuHa3JJF7LvCdt.  (this is not a GUID)
[azureParams UpdateString: @"azure.clientSecret" value: @"CLIENT_SECRET"];

// The subscription ID is a GUID such as 4abd4bf6-5260-4795-90f6-1e91ce4f582c
[azureParams UpdateString: @"azure.subscription" value: @"SUBSCRIPTION_ID"];

// Such as eastus
[azureParams UpdateString: @"azure.location" value: @"LOCATION"];

// With the Azure-specific provider params specified,
// Chilkat will internally fetch the OAuth2 access token using client credentials as needed.
[ai SetProviderParams: azureParams];

// Choose a model.
ai.Model = @"gpt-4o";

// Add a text input.
[ai InputAddText: @"Say Hello."];

// Ask the AI for text output.
success = [ai Ask: @"text"];
if (success == NO) {
    NSLog(@"%@",ai.LastErrorText);
    return;
}

// Get the text response.
CkoStringBuilder *sbResponse = [[CkoStringBuilder alloc] init];
[ai GetOutputTextSb: sbResponse];
NSLog(@"%@",[sbResponse GetAsString]);

// Sample output:
// Hello! How can I assist you today?
