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

loAi = CreateObject('Chilkat.Ai')

* The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
* Support for additional providers will be added in future versions of Chilkat.
loAi.Provider = "openai"

* In this case, we're going to cause an intentional failure by using an invalid API key.
loAi.ApiKey = "sk-11111111111111111111111111111111111111111111111k"

* Choose a model.
loAi.Model = "gpt-4o"

* Add a text input.
loAi.InputAddText("Say Hello.")

* Ask the AI for text output.
lnSuccess = loAi.Ask("text")
IF (lnSuccess = 0) THEN
    * If the response status code equals 0, it means the error occurred before receiving the HTTP response.
    * For this case look at the LastErrorText.
    IF (loAi.ResponseStatusCode = 0) THEN
        ? loAi.LastErrorText
    ELSE
        * If we received an error response, the status code will be >= 400.
        * (Ask would've returned 1 if the response status code was 200.)
        ? "Response status code: " + STR(loAi.ResponseStatusCode)

        * The error response (JSON) is available in the LastJsonData.

        * {
        *   "error": {
        *     "message": "Incorrect API key provided: sk-11111***************************************111k. You can find your API key at https://platform.openai.com/account/api-keys.",
