Check out our sister site NsJson! DNS Lookup and reverse IP API in JSON.

What is WHOIS JSON API?

In essence, WHOIS JSON API is a specially-designed model that collects data points related to domain ownership and registration from an extensive WHOIS database. Whois API, a hosted web service, returns parsed fields to your application in JSON and XML formats based on the HTTP requests. That said, you are relieved of the worries relating to query limits and registrations that domain registrars fix.

Whois API service offers details on WHOIS record data, domain name, IP address, etc. And all this information is parsed and presented in a way your business can easily consume.

Origin Whois servers in real time

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.

Low prices

Our competitors have extremely high prices. We are a small structure so we have lower costs. The satisfaction of our customers is also one of our priorities.
