Email Company Intelligence

This API validates an email address and enriches it with domain intelligence and official company data. It checks whether the email is usable, flags risk indicators (free, generic, disposable, or gibberish), and analyzes the domain for legitimacy through MX validation, age, and stability signals. It then derives the likely associated company, fetches CIN-based records, and performs a name match between the declared and derived company to produce a confidence score and reasoning.

It solves the problem of unreliable email-based identity by bridging the gap between an email and a verified organization. Instead of relying on emails as a weak proxy, it provides standardized credibility signals, links domains to official company records, and reduces manual verification effort. This helps organizations prevent misrepresentation, detect fraud early, and make more confident onboarding and compliance decisions.
