Code Examples

cURL

curl -X GET "https://codequiry.com/api/v1/languages" \
  -H "apikey: YOUR_API_KEY_HERE"
        
            cURL

JavaScript

const response = await fetch('https://codequiry.com/api/v1/languages', {
    headers: { 'apikey': 'YOUR_API_KEY_HERE' }
});

const data = await response.json();

if (data.success) {
    console.log(`Supported languages: ${data.count}`);
    data.languages.forEach(lang => {
        console.log(`${lang.language} (ID: ${lang.id}) - ${lang.extensions}`);
    });
}
        
            JavaScript

Python

import requests

response = requests.get(
    'https://codequiry.com/api/v1/languages',
    headers={'apikey': 'YOUR_API_KEY_HERE'}
)

data = response.json()
if data['success']:
    print(f"Supported languages: {data['count']}")
    for lang in data['languages']:
        print(f"  {lang['language']} (ID: {lang['id']}) - {lang['extensions']}")
        
            Python

Best Practices

Cache the Response: The language list changes infrequently. Cache this response locally and refresh it periodically (e.g., once per day) to reduce API calls.

Language Selection: Use the id field when creating checks. The language ID determines which parser and syntax rules are used for plagiarism detection.

Auto Detect (ID 999): Not sure which language to pick, or handling mixed submissions? Pass language ID 999 ("Auto Detect Language") and the engine detects the source language from the files. If you pass an ID that isn't in this list, the API automatically falls back to Auto Detect instead of returning an error.
