# WebLens, pay as you go: Domain WHOIS API

> Domain intelligence in one call: RDAP registration (registrar, age, expiry, status), live DNS (A/AAAA/MX/NS/TXT), the mail and DNS providers behind them, the SaaS vendors the domain's TXT verification tokens reveal, SPF/DMARC posture, and risk signals like newly-registered or no-registrar-lock.
