Python: search directly by ISIN

julie.osial

I want to be able to search directly by ISIN, as I will start out with only the ISIN available in python and not the Equity RIC. Is there a way via python to figure out the RIC and other features based on solely the ISIN?

Thank you for reaching out to us.

You can use the LSEG Data Library for Python to retrieve RICs from ISINs.

There are several methods.

1.Use the get_data method

ld.get_data(
    universe = ["US4592001014","US30303M1027","US0231351067"],
    fields = ["TR.RIC"])

2. Use the symbol_conversion endpoint

response = symbol_conversion.Definition(
    symbols = ["US4592001014","US30303M1027","US0231351067"],
    from_symbol_type = symbol_conversion.SymbolTypes.ISIN,
    to_symbol_types = [symbol_conversion.SymbolTypes.RIC]).get_data()
response.data.df

3. Use the search.lookup endpoint

symbols = ["US4592001014","US30303M1027","US0231351067"]
response1 = search.lookup.Definition(
    view=search.Views.SEARCH_ALL,                              
    scope="ISIN",                                                  
    terms=",".join(symbols),
    select="RIC",               
).get_data()

response1.data.df

You can refer to the example code on GitHub.

Hello @julie.osial

You can use a Search feature on the https://developers.lseg.com/en/api-catalog/lseg-data-platform/lseg-data-library-for-python to find information you need.

Example code:

import lseg.data as ld

from lseg.data.content import search



ld.open_session()


response = search.Definition(

    view=search.Views.SEARCH_ALL,

    select="ISIN,RIC,....", 

    filter="ISIN eq '<ISIN Code>'" ←- Set your ISIN here

).get_data()

response.data.df

You can find a full example here.
