TypeScript AI Detector

Node.js 18+ includes fetch. This example keeps the API key in an environment variable and sends it as a bearer token.

interface DetectorResponse {
  score: number;
  sentence_scores?: Array<{
    score: number;
    sentence: string;
  }>;
  text: string;
}

async function detectAi(text: string): Promise<DetectorResponse> {
  const apiKey = process.env.SAPLING_API_KEY;
  if (!apiKey) {
    throw new Error('Set SAPLING_API_KEY before running this example.');
  }

  const response = await fetch('https://api.sapling.ai/api/v1/aidetect', {
    method: 'POST',
    headers: {
      Authorization: `Bearer ${apiKey}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({text, sent_scores: true}),
  });

  if (!response.ok) {
    throw new Error(`Sapling API error ${response.status}: ${await response.text()}`);
  }

  return response.json() as Promise<DetectorResponse>;
}

detectAi(
  'I am an artificial intelligence system designed to help people solve complex problems. ' +
  'My capabilities include natural language processing, machine learning, and predictive analytics.',
)
  .then((result) => console.log(JSON.stringify(result, null, 2)))
  .catch(console.error);
