404 error trying to follow the "Analyzing data from a Strapi API with Python" guide

I’m a data analyst & Strapi novice trying to extract some data from an established mobile App & Strapi setup. I’m using this guide “Analyzing data from a Strapi API with Python”. I cannot establish a connection with our server, instead I keep getting a 404 error. Has anyone successfully used this guide, or better yet able to put me in touch with the author? Thanks
