Domain Verification: DNS, RDAP Age, TLS and Website Check

Is this business domain real and established? DNS (MX, SPF, DMARC, DNSSEC), RDAP registrar, creation date and age (never registrant contacts), TLS certificate and live website, plus risk flags like newly registered or invalid TLS. Pay per domain.

What you get

Given a domain, tells whether it is a real, live and established business domain: DNS (A, MX, NS, SPF, DMARC, DNSSEC), registration from RDAP (registrar, created and expiry dates, age, status; never registrant contacts), the TLS certificate (valid, issuer, expiry) and the website (final URL, status, HSTS), with risk flags such as newly registered, no MX or invalid TLS. 'Does not exist' is an answer. Not charged if lookups fail.

Input

• domains (Domains): Domains or URLs; up to 200 per run.
