WHOIS API

WhoisJson API usually pulls records from origin Whois servers in real time, so you get up-to-the minute results. We cache some records for performance, but you can bypass the cache as needed.

WELL-DEFINED FIELDS

Cleans up the records and pulls them apart into well-defined fields. Our system normalizes character sets and line endings, pulls the various fields from the raw text, and puts the fields in a consistent, automation-friendly format (XML or JSON).

AVOIDS QUERY RATE LIMITS

Avoids query rate limits that you would encounter when doing Whois queries from your own IP address. Our system uses caching and a large pool of diverse IP addresses to minimize blockages and ensure that you get the records you need.
