Exception: Resource cams-global-reanalysis-eac4 not found

[Rich2020]

Trying to retrieve data via API results in an exception (see title).
The code used was generated by the CAMS UI located here: https://ads.atmosphere.copernicus.eu/cdsapp#!/dataset/cams-global-reanalysis-eac4?tab=form

Code generated:

import cdsapi

c = cdsapi.Client()

c.retrieve(
    'cams-global-reanalysis-eac4',
    {
        'variable': 'temperature',
        'pressure_level': '1',
        'model_level': '1',
        'date': '2003-01-01/2020-12-31',
        'time': [
            '00:00', '03:00', '06:00',
            '09:00', '12:00', '15:00',
            '18:00', '21:00',
        ],
        'format': 'grib',
    },
    'download.grib')

All terms/conditions accepted and .cdsapirc set according to instructions laid out here (for Mac): https://ads.atmosphere.copernicus.eu/api-how-to

UPDATE: that error is very misleading. The issue was that I need to use the ADS URL and key (rather than the CDS version), as provided here: https://ads.atmosphere.copernicus.eu/api-how-to
It's also very confusing that the instructions on that ADS page explicitly refer to CDS...

Thanks so much. It solves my issues, too.

Thanks! This informataion is very helpful.
The ADS url and key are needed in .cdsapirc file to access the cams-global-reanalysis data.
I also have a test on downloading the ERA5 file. Then it is necessary to update the URL and key to ADS.
