1Lookup has been a good addition to our workflow over the last few months.
We use it to verify IPs, emails, and phone numbers, which has noticeably cut down the time we spend chasing dead-end applications.
It’s reasonably priced and their support team is actually helpful. It's a very practical tool for what we need.
We provide a software service with free trials and were overwhelmed by bots and fraudulent users. After implementing a new filtering solution, the results were impressive. It efficiently screens out invalid signups while allowing legitimate customers through. The support team was also extremely helpful, guiding us in adjusting our risk parameters during a brief video call. Honestly, we couldn't ask for anything better.
We manage a software service with free trials and were inundated with bots and fake accounts. After integrating a new solution, the change was astounding. It seamlessly filters out unwanted signups while letting real customers through. The support team even assisted us in fine-tuning our risk settings during a quick video call. To be frank, we couldn't ask for anything more.
I've experienced numerous validation APIs over time. This one stands out as they don't oversell their capabilities. Their data is robust, support is genuine, and they are open about their limitations—something rare in this field. I've replaced three other tools with this one. They listen, adapt, and continually enhance the service. You can tell there are real engineers behind it, not just salespeople.
We utilize a phone validation API within our telemarketing application to confirm numbers before dialing. The setup was straightforward and the results have been consistently reliable. It’s not cluttered with unnecessary features—just efficient, precise, and dependable. Documentation could be slightly more comprehensive, but it genuinely works right away.
As a backend developer managing a small telemarketing service, this solution has proven to be very dependable. It has identified many invalid or inactive numbers before agents made calls. I would appreciate more metadata like carrier information or last active date, but overall, I have no complaints.
I've been using this solution for a couple of months now. We verify leads before entering them into our CRM. Honestly, it just works. It's not elaborate, not buggy, and the support team responds promptly when contacted. Can't really ask for more.
