Dart AI detector quickstart

Send at least 150 characters for a more reliable signal. The response score ranges from 0 (more likely human-written) to 1 (more likely AI-generated); use it as evidence, not proof.

No language-specific SDK is required. The example uses a standard or commonly used HTTP client to call Sapling's JSON API.
Dart /api/v1/aidetect

Add the http package to pubspec.yaml before running this example.

import 'dart:convert';
import 'dart:io';

import 'package:http/http.dart' as http;

Future<void> main() async {
  final apiKey = Platform.environment['SAPLING_API_KEY'];
  if (apiKey == null || apiKey.isEmpty) {
    throw StateError('Set SAPLING_API_KEY first.');
  }

  final response = await http.post(
    Uri.parse('https://api.sapling.ai/api/v1/aidetect'),
    headers: {
      HttpHeaders.authorizationHeader: 'Bearer $apiKey',
      HttpHeaders.contentTypeHeader: 'application/json',
    },
    body: jsonEncode({
      'text':
          'I am an artificial intelligence system designed to help people solve complex problems. '
          'My capabilities include natural language processing, machine learning, and predictive analytics.',
      'sent_scores': true,
    }),
  );

  if (response.statusCode < 200 || response.statusCode >= 300) {
    throw HttpException(
      'Sapling API error ${response.statusCode}: ${response.body}',
    );
  }

  print(const JsonEncoder.withIndent('  ').convert(jsonDecode(response.body)));
}
Example response application/json
{
  "score": 0.9989,
  "sentence_scores": [
    {
      "score": 0.9764,
      "sentence": "I am an artificial intelligence system designed to help people solve complex problems."
    },
    {
      "score": 0.9812,
      "sentence": "My capabilities include natural language processing, machine learning, and predictive analytics."
    }
  ],
  "text": "I am an artificial intelligence system designed to help people solve complex problems. My capabilities include natural language processing, machine learning, and predictive analytics."
}

The overall score and sentence scores use different methods and may not match exactly. Choose thresholds based on the false-positive and false-negative costs of your use case.
