Is there a limit on number of instruments for Eikon Data API

Hi, I am trying to use the following get symbol API call of Eikon Data API. Is there a limit on number of instruments I can pass to this API ? Where is this documented ?

out = ek.get_symbology(["00287Y109"], from_symbol_type="CUSIP", to_symbol_type="ISIN")

I don't think there's any hardcoded limit, but I also doubt it was ever tested with more than a few thousand symbols in the input. I just tried it with 2,364 Cusips. It worked like a charm.
