Everything in one call

Five intelligence layers in a single, unified API response.

WHOIS / RDAP

Registrar, creation date, expiration, nameservers, DNSSEC status. No paid data sources.

DNS Records

A, AAAA, MX, NS, TXT. Mail provider detection (Google Workspace, Microsoft 365).

SSL Inspection

Issuer, validity, protocol, days remaining. Catch expiring certificates before your users do.

Tech Stack Detection

200+ fingerprints. Identify frameworks, CDNs, analytics, and CMS from HTTP headers and HTML.

Reputation Score

0-100 score based on domain age, SSL, email security, and DNS configuration.

How it works

From signup to production in minutes.
