Error code 429 with LSEG-data Python API

lucamingarelli · 2025-03-28T16:22:25+00:00

There was an error rendering this rich post.

I am getting this error when calling ld.news.get_headline

lseg.data._errors.LDError: Error code 429 | Too many requests, please try again later.

although this was working fine up until yesterday. I have already been waiting for about a day.

Could you kindly help me understand what's going on?

Hello @lucabacciarelli

As explained to Kunal, your application has breached the maximum data limits enforced for the Desktop Session. You can read about these limits in this document. Desktop (LSEG Workspace) is not designated for heavy API usage. We have enterprise grade API like Data Platform which do not enforce the rate limits.

There is no workaround these limits, besides pacing down your application code - i.e. add a wait time in between back to back API calls.

Thanks @Gurpreet . How do I unlock it now? I have not submitted a query all day long really…
By the way my understanding was that the limit was 10 million data points a month: I have certainly queried much less than that. Or how is a datapoint defined? How many "data points" is the body of a news worth?

Aside from that, could you have some representative contacting me related to the enterprise grade API Data Platform?

@Gurpreet Also this link: this document does not work for me: the website gets stuck in a loop as shown below

Do you know your LSEG account manager - they would be the best resource to reach out to. Otherwise I can ask Patrick to get in touch with you.

Also, try to signin from the homepage link - https://developers.lseg.com/en

I get the same loop issue there as well - I have a pop up saying Welcom, Help us personalise your experience and it loops there.

I don't know my account manager no - how can I figure that out?
