AI: Diagnosing an Ask Failure

See more AI Examples

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

import 'package:chilkat/chilkat.dart';

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

  final ai = CkAi();

  // The provider can be "openai", "google", "claude", "deepseek", "xai", or "perplexity".
  // Support for additional providers will be added in future versions of Chilkat.
  ai.provider = 'openai';

  // In this case, we're going to cause an intentional failure by using an invalid API key.
  ai.apiKey = 'sk-11111111111111111111111111111111111111111111111k';

  // Choose a model.
  ai.model = 'gpt-5.6-terra';

  // Add a text input.
  ai.inputAddText('Say Hello.');

  // Ask the AI for text output.
  try {
    ai.ask('text');
  } on ChilkatException catch (e) {
    // 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.responseStatusCode == 0) {
      print(e.lastErrorText);
    } 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.responseStatusCode}');

      // The error response (JSON) is available in the LastJsonData.
      final json = CkJsonObject();
      json.emitCompact = false;
      ai.getLastJsonData(json);
      print(json.emit());

      // 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"
      //   }
      // }
    }
