Display API value in MacOS App

I'm using the free Timeular app from [login to view URL] to track my time I work on projects. As a funfeature I'd like to see how much I've earned already on that project and the current session. The timetracking data, projectnames etc can be received via there API which is documented at [login to view URL] So you just need to pull data from the API and display them. I need a very simply MacOS app that sits right in the menubar at the top of the screen. It should autoupdate every minute and show me the amount I earned in this session for the project active as well as for the set periode of time. In the UI of the app I see all projects that I created in the timeular app (can be pulled via API). Then I set a hourly rate and a periode of time The periode of time needs to be set as I don't want to see how much I earned on this project since the beginning of time but in the current month, since the customer ordered the last time etc. So for this a free input is important. Use system colors and fonts for the interface. See enclosed screenshot for functions and UI. Projectbudget is $20. Use keyword 'timetracking' to show me that you read the description completely before bidding.
