The API worhs for weather_at_place() but not for forecast_at_place()

The API works with:

owm = pyowm.OWM(owm_token)
mgr = owm.weather_manager()
obs = mgr.weather_at_place('Roma')

But if I use:

daily_forecast = mgr.forecast_at_place('Roma', 'daily').forecast

It give me this error:

raise exceptions.UnauthorizedError('Invalid API Key provided')
pyowm.commons.exceptions.UnauthorizedError: Invalid API Key provided

With only the weather_at_place() code it works but if I add at the same program the forecast_at_place() it gives me this error.

reg = owm.city_id_registry()
list_of_locations = reg.locations_for('Mumbai', country='IN')
Mumbai = list_of_locations[0]
lat = Mumbai.lat
lon = Mumbai.lon

one_call = mgr.one_call(lat, lon)

One_call = one_call.forecast_daily[0].temperature('celsius')

print(One_call) 

Does it return temperature for the next day?

@EightFawn I’ve tested your exact code again on my side and it works like a charm

Now, I think here the issue is not with PyOWM but with the API key itself In your very first code snippet you said that querying for observed weather worked but querying for daily forecasted weather didn’t: both queries were working fine on my side.

So here my conjecture is: as my free API key was issued years ago and it seems that it calls OWM API endpoints that are now unaccessible to newer API keys.

I’ve checked out on the OWM API website: it seems that as of today, only calls to the “OneCall” endpoint are enabled for free API key - this might explain why calls work on my side (because I have a kind of “legacy” API key) and don’t work on yours.

This behaviour was completely unexpeted to me 😒

Luckily, you’ll hopefylly be able to retrieve both observed and daily forecasted data using the OneCall methods
