Are there any limits when downloading data using Eikon API

Hi,

I am trying to download ESG data using Eikon API.

I find that I can download the data successfully when I restrict the sample using the following code,

data3, err = ek.get_data("SCREEN(U(IN(Equity(active,public,primary))/*UNV:Public*/), IN(TR.ExchangeCountryCode,""US""),TR.TRESGScore(Period=FY0)>=0,CURN=USD)"

,["TR.CUSIP"])

The number of observations is 3553. I restrict the sample firms with ESG scores only.

But when I relax the restrictions using the following code,

data3, err = ek.get_data("SCREEN(U(IN(Equity(active,public,primary))/*UNV:Public*/), IN(TR.ExchangeCountryCode,""US""),CURN=USD)"

,["TR.CUSIP"])

The number of observations is 13452.

I get the error information:

rror code 413 | Client Error: {"code":413,"message":"request entity too large","stack":"PayloadTooLargeError: request entity too large\n at readStream

So, are there any limits for eikon API? What is the limit?

Thanks,

Hi @c.xue ,

Thanks for your question. Please be aware of the data limits of the APIs by looking at the Eikon Data API Usage and Limits Guideline. You can try chunking the list into smaller pieces and presenting each chunk to the API.

Please let me know in case you have any further questions.
