Authentication & Your First API Request

Learn how to authenticate with the Codequiry API and make your first successful request. All API requests require proper authentication using your API key.

Base API Endpoint

🔐 Authentication Overview

The Codequiry API uses API key authentication. You must include your API key in the apikey header with every request. This ensures secure access to your account and maintains proper usage tracking.

Note: Keep your API key secure and never expose it in client-side code. Treat it like a password.
Required Headers
  • apikey: YOUR_API_KEY - Your authentication token
  • Accept: application/json - Specify response format
  • Content-Type: application/json - For POST/PUT requests with JSON data

🚀 Test Authentication: Get Account Information

The /account endpoint is perfect for testing your authentication setup. It returns your account details and current usage statistics without consuming any API credits.
