Frequently Asked Questions

Q. Where can I get an API key?

You can generate API keys through the Members Area.

Q. Which domain extensions (TLDs) are supported?

The latest list can be downloaded at https://www.autowhois.com/tlds.txt

Q. Will I get Raw WHOIS in JSON/XML?

Yes! Raw WHOIS will be included along with the parsed WHOIS data in both JSON and XML response.
In case of .com and .net domain names, Raw WHOIS from both the domain registry and registrar will be included.

Q. What are cached WHOIS records?

The most recent WHOIS of a domain stored in our server can be provided through cache, at a speed 10 times faster than live WHOIS. Similar to live WHOIS, you will be charged a single API query per domain name. The maximum age of cache would be 7 days. We recommend using cached WHOIS for popular domain names, as their most recent WHOIS would be readily available in our cache.

Q. Am I charged for empty WHOIS or failed queries?

No! Your account balance will only be deducted for successful WHOIS lookups.
In case of cached WHOIS, you will be charged only if the domain's WHOIS record is present in our cache.

Q. What are the API usage limits?

Your application may query our API for a maximum of 25,000 times in an hour.
If your application exceeds the above limit, further requests will be dropped.
