Good tool, no fluff
Been using 1Lookup for a couple months now. We verify leads before pushing them into Pipedrive. Honestly it just works. Not fancy, not buggy, and the support actually answers when you write them. Can't really ask for more.
Brian LetzterUnited States · October 2025The most practical data tool I've used
I've seen hundreds of validation APIs come and go. 1Lookup stands out because they don't oversell. Their data is solid, support is honest, and they're transparent about limitations, which is rare in this industry. I've replaced three tools with this one. They listen, they iterate, and they keep improving. You can feel there are actual engineers behind it, not just salespeople.
Bùi Thị Thanh NgọcVietnam · October 2025Solid phone validation API
We use 1Lookup inside our telemarketing app to verify numbers before they go to the dialer. Setup was simple and the results have been consistent. It's not overloaded with features, just fast, accurate, and reliable. Docs could be a bit deeper, but honestly, it works out of the box.
Dirk van MeerUnited States · December 2025Saved us from hundreds of spam signups
We run a SaaS product with free trials and were getting flooded with bots and fake users. After integrating 1Lookup, the difference was night and day. It quietly filters out junk signups without blocking legitimate customers. The support team even helped us fine-tune our risk thresholds on a quick Zoom call. Being honest, we couldn't ask for more.
Ido ShachamUnited States · January 2026A good addition to our workflow
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.
