Awesome service, very helpful and understanding support I needed VPN information access for a VPN blocker, but we’re just a startup. I thought this service provided that, well it does but I thought that it was free. I got an email asking if I wanted to share the reason I wasn’t using their service, about a week after I signed up. I explained the issue, and they were VERY helpful and understanding. After a few more email exchanges, I had to fill out a form, and they gave me access to 10k ‘privacy’ (vpn checks etc) API requests a month! Thank you so so much, and I really like the service and will keep using it for my VPN blocker :)

Clean, Accurate, and Easy Domain Data The API was easy to use, and the data has been clean and reliable. We use the domain data from Host.io to help populate our private company database. We've found it to contain less "noisy internet" data and a higher number of real businesses/websites than other sources we've reviewed. No dislikes come to mind, everything is working as expected.
