Quickstart

OpenRegister provides multiple integration options to fit your technical setup and use case. Whether you’re building a custom application, automating workflows, or adding AI capabilities, we have you covered.

​

Choosing the Right Integration

​

For Developers

Use our SDKs if you’re building a custom application and want:

• Full type safety and autocompletion
• Native language integration
• Complete control over API calls

Available in Python, TypeScript/JavaScript, and Go. View SDK Documentation →

​

For No-Code Automation

Use n8n or Zapier if you want to:

• Automate workflows without writing code
• Connect OpenRegister with other tools (CRMs, databases, spreadsheets)
• Build data enrichment pipelines

Both platforms offer visual workflow builders with pre-built OpenRegister actions. n8n Documentation → | Zapier Documentation →

​

For AI Assistants

Use the MCP Server if you want to:

• Enable AI assistants like Claude to query company data
• Build AI-powered tools with access to German company information
• Integrate with Model Context Protocol-compatible clients

​

Direct REST API

Use the REST API directly if you:

• Need maximum flexibility
• Work in a language without an official SDK
• Prefer making raw HTTP requests

All SDKs and integrations are built on top of our REST API. API Reference →

​

Authentication

All integration methods require an API key. Get yours in under a minute:

1. Create an account at openregister.de
2. Go to API Keys
3. Generate your key

The free plan includes 50 requests per month - perfect for testing. Authentication Guide →
