Review the API Documentation

Visit the official Gutendex documentation to understand available endpoints, request formats, and response structures. Familiarize yourself with the API's rate limits and usage policies before integration.

2

No Authentication Required

Good news — Gutendex does not require any authentication. You can start making API requests directly without registering for an API key or setting up OAuth credentials.

3

Use HTTPS for Secure Requests

Gutendex supports HTTPS, ensuring encrypted communication. Always use HTTPS endpoints in production to protect data in transit and comply with modern web security standards.

4

CORS Status Unknown — Test Before Use

The CORS status for Gutendex is unknown. Test with a simple browser-based request to verify. If CORS is not supported, set up a backend proxy to handle requests server-side.

    }
    return response.json();
  })
  .then(data => {
    console.log("API response:", data);
