Customer Reviews
Good API, easy setup
I used the Phone Validation API for a quick project. Documentation was clear. Integration took less than an hour. It handled all the numbers fine.
Real-time verification worked
I needed the Real-time Phone Verification for a new signup flow. It caught a few suspicious numbers right away, which was good. The API responded fast, no noticeable lag for users. I tested it with international numbers too, and that worked as expected. Support got back to me quickly when I had a question about batch processing.
