APIs/Domain

Domain API

GET /domain/{domain}

Check if a domain is available for registration. Core provides a simple domain availability flag.

On paid plans, deep adds A, AAAA, nameservers, MX, TXT, a mail provider guess, and registration details (created, expires, registrar). For MX alone, use /mx/{domain}.

SPEED

Fast from everywhere.

Median time for a /domain response to reach a real city, first byte back, measured live from 16 cities. Not a lab benchmark. The whole trip.
