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.
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 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.
