# Quickstart

> Get started with the OpenRegister API in minutes

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.

## Set Up with an AI Agent

The fastest way to integrate: paste this prompt into Claude Code, Cursor, or any coding agent, and it will handle the setup for you — API key configuration, SDK installation, and a verified first request.

Add OpenRegister to my app: openregister.de/skill.md

## 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 →](/integration/sdks)

### 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.

### 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

[MCP Documentation →](/integration/mcp)

### 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.
