I found out, that when you make an account, you can make the token,
Like I said in the question, you can make a token, when you sign up here: https://openrouteservice.org/
Sign Up is at the top right corner ish.
after signing up, you will receive an activation email (also check your spam folder)
- click the activation link in the email which takes you to the ors dashboard login page
- log in to your ors dashboard which brings you to the home view which contains no token yet.
- choose the token type and give the token a name and click the
create tokenbutton to get your free API key
When you are logged in your valid API key is automatically added in requests generated with the API Playground which you can use to test out and get used to the API.
