GoURL.io is a service that allows users to shorten and monetize their URLs. Users can input a raw URL, and GoURL.io will create a shortened URL with a Speedcoin captcha box. Speedcoin is a cryptocurrency similar to Bitcoin. Visitors must make the Speedcoin captcha validation in order to follow the URL. The GoURL.io URL Shortener API enables developers to create, inspect, and manage shortened and monetized URLs from within their own websites or applications.
