We have been using this URL for years to retrieve some ERA5 single levels data in our Python code:

CDS\_API\_ERA\_URL = “[https://cds.climate.copernicus.eu/api/resources/reanalysis-era5-single-levels](https://cds.climate.copernicus.eu/api/resources/reanalysis-era5-single-levels)”

With the new API, this path is no longer working, receiving this error:  
**HttpProcessingError: 404, message:\n {"message":"Not Found"}",“exception\_name”:“HttpProcessingError”}**

Any ideas to what we should change the URL to? Any help highly appreciated.
