You can register on our Dashboard. After you have verified your account, you can log in. We have already created an initial API key for you, which you can use to get started directly in the Paper Trading API.

Find out more about opening a securities account and all the special features of the Trading API in the section "Securities Account & Partner Bank".

Currently, the Trading API is still in closed beta. Stay up-to-date with the latest news by joining our Slack Community or following us on LinkedIn. For now, you can already register for the Paper Trading API and test diligently with it as you will need to meet certain criteria there (create 2 Spaces, execute 20 transactions) to upgrade your account from Paper Trading environment to Trading environment. 

In the Dashboard you will find an overview of your Spaces, Orders, and Transactions. You can also create new API keys and spaces in the dashboard.
