How to set up the Python API?

How do I set up the Python access? I have a Refinitiv Workspace, is there a page describing the configuration necessary?

want to accept the answer with the proposal to check and upgrade the version of the anyio package but I can't see it, did you delete by mistake?

I think it requires anyio version 3.x or 4.x.

I am using anyio 3.3.4.

Thanks. I see 2 alternative packages documented: eikon and refinitiv-data. Are there advantages/disadvantages of working with either?

Follow-on question, maybe you can point to the source of the error I receive after trying to set the app key:

ek.set_app_key(XXXX)

[MainThread 16232] Error: no proxy address identified.
[MainThread 16232] Error on handshake url http://127.0.0.1:None/api/handshake : InvalidURL("Invalid port: 'None'")

Regards,

Hello @claudiu.schiller

The Eikon Data API is a feature-completed API, the Data Library for Python is the strategic API currently. The new API features will be added to the Data Library only. You can find more detail about Pros and Cons from this Upgrade from using Eikon Data API to the Data library article.

About the issue that you are facing. The Eikon Data API (or Data Library - Desktop session) needs to connect to the Workspace/Eikon desktop application in the same machine (localhost/127.0.0.1 ports 9060 and 9000) as a proxy between the API and the platform. Did you run the Workspace/Eikon desktop application in the same machine as the Python script?

Please try the steps on the following resources:

Eikon Data API and Refinitiv Data Library - Troubleshooting article.

Thanks for the pointer. I did check the workspace is running and followed the troubleshooting article to show the DATA API PROXY is Ready. The older posts seem to indicate a library version incompatibility which I'm not sure is still relevant. Any pointers? Let me know if a new post would be better that continuing in this thread.

Hello @claudiu.schiller

I did a quick test. The Eikon Data API version 1.1.18 works fine with httpx version 0.27.0 on my end.

Based on this What version of Eikon (Core, Research and Advisory, Premium) do you need to use the Python Data APIs? old post, the Eikon Data API (and Data Library - Desktop session) supports the Workspace/Eikon premium user only. Please confirm if your Workspace is premium account (you can contact your LSEG representative for more detail).

If you are already on the premium account, please follows the following instructions.

Please confirm version of your eikon, httpx and nest-asynco library (you can use pip show command)
Does your environment have a firewall or proxy policy that block connect to localhost? You need to contact your local IT team for this.
Enable the API logging, please see section "2.1.2) Enable logging" of the troubleshooting article for more detail. Then share a full log messages when the problem occurs here.

Please check the version of anyio used in the application.

anyio at 2.2.0

I can install newer and check tomorrow if this is the cause (installing new packages in our env is a bit complex)

Hello @claudiu.schiller

I am using anyio version 3.4.0. Please try to upgrade the anyio as suggest by my colleague above.

pip install anyio --upgrade

or

pip install anyio==<version> --upgrade

You can check the versions of anyio from the PyPI history page.

Upgrading anyio to v3.4 helped. Now I get data. Thanks a lot for the help.

Hello @claudiu.schiller

I am glad to hear that the issue is resolved on you end.

I strongly suggest you keep this environment setting for later use. You can use the pip freeze command to generate a requirements file and then install from it in another environment.

python -m pip freeze > requirements.txt

To install the same set of libraries versions:

python -m pip install -r requirements.txt
