OpenRegister crawls and analyzes company websites to extract publicly available contact information and social media profiles. Our API enriches official register data with real-world contact details and online presence, bridging the gap between official registrations and current business operations.

​
What You Get

  • Contact information - Email addresses and phone numbers

  • Social media profiles - LinkedIn, Instagram, GitHub, Twitter, Facebook, YouTube, Xing, TikTok
