Unable to download data using DSWS API in Python

lucadamico

Hi, I am no anymore able to download data via DSWS API in Python. A few days ago everything worked properly, but suddenly is not working anymore. Please see below my request and the error that I got. I have already checked my credentials here and everything seems okay.

import DatastreamDSWS as DSWS

# set datastream username and password
ds = DSWS.Datastream(username = 'XXXXXXX', password = 'XXXXXX', proxy="PROXYXXX")

# get data from Datastream
dat = ds.get_data(tickers='S&PCOMP', fields=['RI'],start='2018-01-01', end='', freq='D', kind=1)
dat

get_data : Exception Occured
(<class 'TypeError'>, TypeError("argument of type 'NoneType' is not iterable"), <traceback object at 0x000002B39B676C88>)
None

I am wondering if it may be that I reached the limit of download. Is it possible to check it?

Many thanks

Hi @lucadamico, Since you are still having the same issue with DatastreamPy, it is indeed possible that you reached your data limit. Info on the data limit on 'DSWS user stats and limits', specifically how to check if you reached the limit under 'Usage review for Desktop service'.

Hi @lucadamico, The Datastream library for python was updated to DatastreamPy. Would you mind trying your script with it and letting us know if you are still having issues?

Hi @jonathan.legrand, I have checked and my access is temporarily suspended because I have reached the limit for this month.

Many thanks for your prompt support.

Have a great weekend.
