All API endpoints require authentication using an API key. You must include your API key in the Authorization header of each request using the Bearer token format.

​
Getting an API Key (takes under a minute)

  1. Create an account at openregister.de
  2. Go to the API Keys page
  3. Create a new API key

Each account has rate-limits depending on the plan you have chosen. Some endpoints are only available to paid subscribers. If you need higher rate limits, please contact us at founders@openregister.de.

Using the API Key
