Hi Product Hunt! 👋 I’m Aristoteles, founder of CheckHim. I built it because too many teams waste SMS and voice costs sending messages to invalid or unreachable numbers. CheckHim offers a lightweight, developer-friendly API for real-time phone number verification with global response times under 100ms. I’m especially proud of our clean API design, clear documentation, and privacy-first processing—numbers are handled transiently with no personal data enrichment. Your feedback means a lot! What features would make your integration even smoother?
