What is the best way to figure out the primary RIC when I have some other identifier - like ISIN, etc? I found this article https://developers.refinitiv.com/en/article-catalog/article/isin-to-ric-conversion-with-dss-datascope-select-rest-api
and was able to get what I need by doing a terms and conditions on demand extraction. But from what I understand, my firm will be charged for these requests and I'm not 100% clear on how much.
I also found, through a different API, that there is a search that can be done, using SearchContext and EquitySearch. This API returns back quicker than the extraction, but it gives me a list of all RICs for the company - i.e. every exchange it trades on, and I'm not clear if there is a way to distinguish which RIC is the primary.
Is there a way to get the primary RIC using SearchContext, and does this also incur a charge on my account?
Is there any other way to accomplish what I need? I thought I remember hearing about some sort of open symbology for TR customers to use, but wasn't able to find anything about this.
Thanks..
