Api Endpoint

Factline

Domain and website risk check: registration age, registrar, email setup, disposable domains. Use when you need to judge whether a website or email domain is trustworthy: registration date and domain age (RDAP), expiry, registrar, nameservers, email setup (MX, SPF, DMARC), disposable-email domains, and a low/medium/high risk with flags such as 'registered 4 days ago', a common sign of scam shops. Accepts a domain, URL or email.
