How do I get my API data without having a domain?

Hi Everyone,

How do I get my API data so that I can integrate it into a Python script?

These are available easily on Spotify in my account. But here you seem to have to create an app and add a web domain? I don't have a web domain and I don't want to integrate the API data into a web domain, I just want to use it for myself for a little Python Script.

Best regards, Robert
