AI: Diagnosing an Ask Failure

See more AI Examples

Demonstrates how to get information about why a request to the AI provider failed. Ruby

require 'chilkat'

success = false

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

ai = Chilkat::CkAi.new()

#  The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
#  Support for additional providers will be added in future versions of Chilkat.
ai.put_Provider("openai")

#  In this case, we're going to cause an intentional failure by using an invalid API key.
ai.put_ApiKey("sk-11111111111111111111111111111111111111111111111k")

#  Choose a model.
ai.put_Model("gpt-5.6-terra")

#  Add a text input.
ai.InputAddText("Say Hello.")

#  Ask the AI for text output.
success = ai.Ask("text")
if (success == false)
    #  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 (ai.get_ResponseStatusCode() == 0)
        print ai.lastErrorText() + "\n";
    else
        #  If we received an error response, the status code will be >= 400.
        #  (Ask would've returned true if the response status code was 200.)
        print "Response status code: " + ai.get_ResponseStatusCode().to_s() + "\n";

        #  The error response (JSON) is available in the LastJsonData.
        json = Chilkat::CkJsonObject.new()
        json.put_EmitCompact(false)
        ai.GetLastJsonData(json)
        print json.emit() + "\n";

        #  Sample output:
        #  {
        #    "error": {
        #      "message": "Incorrect API key provided: sk-11111***************************************111k. You can find your API key at https://platform.openai.com/account/api-keys.",
        #      "type": "invalid_request_error",
        #      "param": null,
        #      "code": "invalid_api_key"
        #    }
        #  }
    end

    exit
end

#  Get the text response.
sbResponse = Chilkat::CkStringBuilder.new()
ai.GetOutputTextSb(sbResponse)
print sbResponse.getAsString() + "\n";
