I was wondering if anyone here knows of a whois lookup service that allows unlimited automated lookups? I have tried searching Google, but have had no luck finding one, Does anyone here know of either a free or paid service that I would be able to use for this purpose? Thanks for any suggestions
i had created a similar service for one of my clients some time ago it allows unlimited lookups msg me if interested.
You could create your own. Here is a PHP Script I wrote that queries WHOIS servers to fetch domain availability, With some minor modification it could be used to show you the WHOIS info instead of parsing it to check if the domain is registered. The thing about "unlimited automated lookups" is that the WHOIS servers themselves has rate limiting on the requests that you can poll from it, so you would have to implement some sort of proxy rotation feature, although not very hard to do it would become expensive and/or inconvenient.
There aren't many good solutions to this unfortunately. The only ones I found worthwhile are paid API's that handle the processing for you.
