NOAA Weather REST API throws error when requested with curl

I am trying to write a python program using NOAA Climate Data Online REST Web Services ( http://www.ncdc.noaa.gov/cdo-web/webservices/v2#data ). But I am running into errors in my request for answers. When trying to request with curl from the command line, I enter:

curl -H "token:<MYTOKEN>" http://www.ncdc.noaa.gov/cdo-web/api/v2/data?datasetid=GHCND&locationid=ZIP:22405&startdate=1999-10-05&enddate=1999-10-25

      

        
        
        
      

    

It returns this response:

[1] 24322
[2] 24323
[3] 24324

[1]   Done                    curl -H "token:..." http://www.ncdc.noaa.gov/cdo-web/api/v2/data?datasetid=GHCND
[2]-  Done                    locationid=ZIP:22405
[3]+  Done                    startdate=1999-10-05

      

        
        
        
      

    

For some reason, it thinks I am missing a start date, but I included it and it matches the format as per the documentation. Does anyone have any ideas on what the problem might be?
