I don't think third parties even really try to organize and do the boring work of proving themselves in local/state office.
They are just spoilers; you don't see the Libertarians or Greens saying "you know what, forget the presidency, obviously we aren't going to win--let's field candidates for like mayor, city council, DA, state legislature, etc. in really swingy/purple districts and show people what we can do"
Yep, the pure delusional thinking required to seriously run for the presidency when they don't have a single elected federal position anywhere. It's beyond absurd.
Came here to post this. We use Django Ninja at work (basically FastAPI style endpoints for Django), and it automatically does OpenAPI and Swagger docs for us. Whatever web framework one chooses in whichver language should def have this built-in by now, IMO, seems like tablestakes for anything larger than a "micro-framework"
