# Web Data

> The OpenRegister API provides access to contact information and social media data extracted from company websites.

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
* **Tax identifiers** - VAT ID and Tax ID from company websites
* **Social media profiles** - LinkedIn, Instagram, GitHub, Twitter, Facebook, YouTube, Xing, TikTok
* **Website verification** - Link websites to official company entities
* **Source tracking** - See where each piece of information was found

This data is particularly valuable for sales, marketing, and due diligence when you need current contact details beyond what's in official registers.

## Use Cases

**Sales & Marketing** - Enrich CRM data with contact information and social media profiles for targeted outreach campaigns. Build prospect lists with verified email addresses and phone numbers.

**Due Diligence** - Verify company legitimacy by matching websites to official register entries and checking online presence. Identify inconsistencies between registered information and current web presence.

**Lead Enrichment** - Start with a website URL and discover the company's full profile including ownership structures, financial reports, and contact details. Perfect for lead scoring and qualification workflows.

**Competitive Intelligence** - Track competitors' social media presence and online activities. Monitor changes in contact information and web presence over time.
