How to Use This API

1. Basic Detection

https://api.languagelayer.com/detect?access_key=YOUR_KEY&query=Bonjour%20tout%20le%20monde

Returns: {"success":true,"results":[{"language_code":"fr","language_name":"French","probability":99.8,"percentage":99.8}]}

2. Bulk Detection (Multiple Texts)

https://api.languagelayer.com/detect?access_key=YOUR_KEY&query[]=Hola%20mundo&query[]=Hello%20world

Submit up to 10 texts in a single request using array syntax.

3. JavaScript — Auto-Detect Page Content

async function detectLanguage(text) {
  const apiKey = 'YOUR_API_KEY';
  const resp = await fetch(
    `https://api.languagelayer.com/detect` +
    `?access_key=${apiKey}&query=${encodeURIComponent(text)}`
  );
  const data = await resp.json();
  
  if (data.success && data.results.length) {
    const result = data.results[0];
    return {
      code: result.language_code,
      name: result.language_name,
      confidence: result.percentage
    };
  }
  return null;
}

detectLanguage('¿Cómo estás?').then(lang => {
  if (lang) {
    console.log(`Detected: ${lang.name} (${lang.code})`);
    console.log(`Confidence: ${lang.confidence}%`);
  }
});

4. Python — Language Classifier for Text

import requests

def detect_text_language(text, api_key):
    resp = requests.get(
        'https://api.languagelayer.com/detect',
        params={
            'access_key': api_key,
            'query': text
        }
    )
    data = resp.json()
    
    if data.get('success') and data.get('results'):
        result = data['results'][0]
        return {
            'language': result['language_name'],
            'code': result['language_code'],
            'confidence': result['percentage']
        }
    return None

api_key = 'YOUR_KEY_HERE'
samples = [
    'The quick brown fox jumps over the lazy dog',
    'Je ne parle pas français',
    'Hallo, wie geht es dir?',
    'Ciao, come stai?',
    '今日はいい天気ですね'
]

for text in samples:
    result = detect_text_language(text, api_key)
    if result:
        print(f"\"{text[:30]}...\" -> {result['language']} ({result['confidence']}%)")
