Checker.soax.com appears to be a subdomain that doesn't actually serve a working website. Instead of a functional tool or service, visitors see a plain 404 error page. For a legitimate SaaS provider, this is a glaring red flag: even a minimal landing page or a maintenance notice would be expected. Most credible software-as-a-service companies have at least a company name, a contact email, and some form of legal documentation. Here, there is none of that. The domain has no presence in web archives, no social media accounts, and no identifiable owner. While the SSL certificate is technically valid, it doesn't matter when the site itself is broken. If you're considering using checker.soax.com for any purpose, there is simply not enough evidence to suggest it's a real, operating business. The safest move is to avoid it entirely.
