*  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-5.6-terra"

*  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.
