Weatherkit API Historical 404 Errors Starting 3/5/25

We've been using the WeatherKit API for a few years now. Everything has been pretty stable. We'll periodically get 404 errors, but they usually disappear within a couple days.

Starting March 5th we've again been getting 404 errors that slowly ramped up to March 20th and continued. We have had no code changes on our end, so something seems to have changed / broken on the server side of things.

Here are some example API calls that are giving us a 404 error now

https://weatherkit.apple.com/api/v1/weather/en/35.9981205/-78.8920444?dataSets=forecastDaily&dailyStart=2025-03-21T05:00:00Z&timezone=America/New_York&countryCode=US

Does anyone have any insights or information on this?

Also if Apple is listening, an error more meaningful than 404 would be much much appreciated.
