Not at all! The api is available without an account at https://www.styvio.com/api/AAPL The docs are super well done and available on our homepage after you login!
this leads to a Django debug page because you linked incorrectly.
The bigger problem though is running debug=True in production. you should change that asap it's a security hole.
What docs? I made an account and haven't learned anything from the docs that I have not already reverse engineered in a minute from the two sentence comment I am replying to.
