In order to use our API you need to get your xi-api-key first. Create an account, log in and in the upper right corner click on your profile picture -> profile.
Next click on the eye icon on your profile to access your xi-api-key. Do not show your account to anyone else. If someone gains access to your xi-api-key he can use your account as he could if he knew your password.
You can generate a new xi-api-key at any time by clicking on the spinning arrows next to the text field. This will invalidate your old xi-api-key.
