EikonError: Error code 413 | Client Error: Payload Too Large get symbology

Hi I am converting around 13000 cusip, isin, and sedol to ric using eikon API and I am feeding into get_symbology a list of identifiers. I got the error 413: client error: payload too large even I try to shrink the list to as small as 5 entries. Does any one know what is the restriction eikon has on the size of list input? Thanks!

I split my list into 100 blocks. Even 1000 does not work for me.

@yiliu.lu symbology api can be safely used on large datasets (think index constituents code conversion for a large index), so it is difficult to say what causes this behavior without looking at your code.

I may only assume that something went wrong after you attempted to execute the initial 13000 symbols as one request, however, it is something that I failed to replicate.

If this problem persists, please let us know.

Thanks! @Zhenya Kovalyov I am merging factset(that uses cusip) with eikon to fill in some missing entries. running the following line of code:

cric=ek.get_symbology(cusip,from_symbol_type='CUSIP',to_symbol_type='RIC')['RIC']

Where cusip is a list of 13000 cusips that I need to convert to ric.

The complete error message I got is:

I think it might be a restriction on the server side. Any thoughts? Thanks a lot!

I suggest you split your list into several smaller ones. Rather than using a single list of 13K Cusips try doing your Cusip to RIC conversion in a loop with 13 lists of 1K Cusips each.

I split my list into 100 blocks. Even 1000 does not work for me.
