I am doing some easy trials to access the API and I have errors everywhere, I would really appreciate some help.
This is my code and the error:
from pathlib import Path
import cdsapi, datetime as dt
1) Escribimos el .cdsapirc sin espacios extras ni BOM
rc = Path(r"C:\Users\Vicente Collado.cdsapirc")
rc.write_text(
“url: https://cds.climate.copernicus.eu/api\n”
“key: UID:TOKEN\n”,
encoding=“utf-8”,
)
2) Cliente - ahora debería salir “Using key authentication with URL …”
c = cdsapi.Client(quiet=False)
3) Solicitud mínima de prueba (solo 1 hora de un día)
c.retrieve(
“reanalysis-era5-land”,
{
“product_type”: “reanalysis”,
“variable”: “2m_temperature”,
“year”: “2024”,
“month”: “01”,
“day”: “01”,
“time”: “00:00”,
“format”: “netcdf”,
},
“test_era5.nc”,
)
print(“¡Petición lanzada!”, dt.datetime.now())

Exception: Climate Data Store API endpoint not found
It seems you are trying to access an API endpoint that does not exist.
It is possible that you are pointing to an outdated API endpoint which has been removed/renamed.
If you are using the standard cdsapi Python library, please ensure that:
- your cdsapi version is updated
- your .cdsapirc file is correctly configured (“url” should be set to CDSAPI setup<!-- --> - <!-- -->Climate Data Store and “key” should be set to your API key WITHOUT the
<UID>:prefix)
If you are trying to access a REST API endpoint directly, please refer to the documentation for more information on how to access REST API endpoints:
CDSAPI setup<!-- --> - <!-- -->Climate Data Store
