Hi,
I recently tried using the new beta version of the API and encountered an issue that I thought might interest you. Even when following the official example provided, I’m faced with an error. Here’s the code I used:

import cdsapi
client = cdsapi.Client()
dataset = 'reanalysis-era5-pressure-levels'
request = {
  'product_type': ['reanalysis'],
  'variable': ['geopotential'],
  'year': ['2024'],
  'month': ['03'],
  'day': ['01'],
  'time': ['13:00'],
  'pressure_level': ['1000'],
  'data_format': 'grib',
}
target = 'download.grib'
client.retrieve(dataset, request, target)

However, I’m getting the following error:

HTTPError: 404 Client Error: Not Found for url: https://cds-beta.climate.copernicus.eu/api/resources/reanalysis-era5-pressure-levels
During handling of the above exception, another exception occurred:

I’m puzzled as to why this is happening. Is it possible that the new version of the API is not ready for data downloads yet? I would appreciate any insights you might have on this issue.
Best regards,
Wang

hi Wang, i just tried your request and it ran ok:

% more forum.py  
import cdsapi
client = cdsapi.Client()

dataset = 'reanalysis-era5-pressure-levels'
request = {
  'product_type': ['reanalysis'],
  'variable': ['geopotential'],
  'year': ['2024'],
  'month': ['03'],
  'day': ['01'],
  'time': ['13:00'],
  'pressure_level': ['1000'],
  'data_format': 'grib',
}
target = 'download.grib'
client.retrieve(dataset, request, target)
 % python3 forum.py

So it may have been a temporary issue on cds-beta

Hi Kevin,
Thanks for your reply. I suspect there might be an issue with my .cdsapirc file configuration. I’ve set it up as follows:

url: https://cds-beta.climate.copernicus.eu/api
key: UID (formatted as ********-****-****-****-************):Personal Access Token (tried both uppercase and lowercase, but no success)

Unfortunately, it didn’t work. Any new suggestions?

Best regards,
Wang

Maybe set your file as follows:

url: https://cds-beta.climate.copernicus.eu/api
key: [key here]

The inclusion of your UID within the .cdsapirc file is gone for the CDS-beta system. In the past you indeed needed to list both user id & key, now just the key.

The old one looked like:

But the new one looks like:

The other topic post on this.

also, if you logon to the CDS-beta and go to
https://cds-beta.climate.copernicus.eu/how-to-api
you should see your details for what should be included in your .cdsapirc file
