I'll upload a video in this lesson within a few days with a full analysis of the PyJobs API. For now, please use this specification as a reference for the lessons and the exercises. The YAML version is available here, and if you want to get the Swagger visualisation I use in the upcoming lessons, paste the YAML spec on the left-side panel of this editor (you'll get the view below). In the meantime, any questions about this please let me know!
