I would like to use the Eikon API to import market data via Python.

Uday_PK

I followed the procedure by generating an Eikon Data key and installing the Python Eikon package. However, when I run my Python code:
python

import eikon as ek
ek.set_app_key('MY_KEY')
I get the following message in my terminal:

2026-04-20 10:22:02,133 P[21940] [MainThread 22052] Error: no proxy address identified.
Check if Eikon Desktop or Eikon API Proxy is running.
2026-04-20 10:22:02,138 P[21940] [MainThread 22052] Error on handshake url http://127.0.0.1:9005/api/handshake : TypeError("cannot create weak reference to 'NoneType' object")
2026-04-20 10:22:02,139 P[21940] [MainThread 22052] Error on handshake url http://127.0.0.1:9005/api/handshake : TypeError("cannot create weak reference to 'NoneType' object")
2026-04-20 10:22:02,140 P[21940] [MainThread 22052] Port number was not identified, cannot send any request

Yet, my key is activated (status "enabled"), and in the settings -> Data API Proxy, the status indicated is "ready".

Would you be able to help me resolve this issue?
Thank you in advance for your assistance.

Thank you for reaching out to us.

The Eikon Data API is relatively old and has not received updates since October 2023.

Please use the new LSEG Data Library for Python. To migrate the code, please refer to this Essential Guide to the Data Libraries - Generations of Python library (EDAPI, RDP, RD, LD) article.
