3 months ago I have the same issue when attempting to use USApplication.get too often. The USPTO API seems to lock up after some number of uses and then returns 403 for a while after.
I visited https://ped.uspto.gov/api/queries after getting locked up and it had this result in Firefox:
403 ERROR

I am getting the below exceptions regularly after fetching 115-120 applications in my django rest framework. Initial investigation pointed to peds rate limiter, but on restart I am able to fetch another 120 set. So something is wrong in USApplication.objects.get(application_number).
Below is the error stack trace:
