Overall looks good! I tested this and it seems to work for basic use cases.

I didn't see any tests included in this PR, please add that when you get a chance!

Hi Caellum, I fixed the key issue in the backend CI and merged it into your branch for you. Please take a look and let me know if there's any questions. The pipeline is passing for you now!

Thank you Ethan and Vivian,

I've added some additional tests in the tests.py file and swapped the made up key so that it uses the server .env files. If I missed anything, please let me know!
