Hello @modaresi,

You could do this in two seps:

1. First, identify the RIC, that is specific to exchange, via Search
2. Second request an Extraction of that RIC, request EOD

Identify the RIC:

You can run a generic InstrumentSearch for your Isin and from the results, select the RIC that you require, for example:

{ {protocol}}{ {host}}{ {api}}Search/InstrumentSearch

{
  "SearchRequest": {
    "InstrumentTypeGroups": [
      "CollatetizedMortgageObligations",
      "Commodities",
      "Equities",
      "FuturesAndOptions",
      "GovCorp",
      "MortgageBackedSecurities",
      "Money",
      "Municipals",
      "Funds"
    ],
    "IdentifierType": "Isin",
    "Identifier": "US4592001014",
    "PreferredIdentifierType": "Ric"
  }
}

Yields various RICs that can be used to extract:

...
{
            "Identifier": "IBM.TH",
            "IdentifierType": "Ric",
            "Source": "THM",
            "Key": "VjF8MHgwMDAzZGQwMDEzNzlkNDYwfDB4MDAwM2RjMDA0ODNmMDRhY3xUSE18RVFRVXxFUVRZfE9EU0h8RXx8SUJNLlRIfDAxNzQ",
            "Description": "INTERNATIONAL BUSINESS MACHINES ORD",
            "InstrumentType": "EquityQuote",
            "Status": "Valid"
        },
        {
            "Identifier": "IBM.D",
            "IdentifierType": "Ric",
            "Source": "DUS",
            "Key": "VjF8MHgwMDAzZGQwMDEzNzlkNDYwfDB4MDAwM2RjMDA0ODY3MWNlY3xEVVN8RVFRVXxFUVRZfE9EU0h8RXx8SUJNLkR8MDEwMw",
            "Description": "INTERNATIONAL BUSINESS MACHINES ORD",
            "InstrumentType": "EquityQuote",
            "Status": "Valid"
        },
        {
            "Identifier": "IBM.P",
            "IdentifierType": "Ric",
            "Source": "PSE",
            "Key": "VjF8MHgwMDAzZGQwMDEzNzlkNDYwfDB4MDAwM2RjMDA0OGEzMzgwY3xQU0V8RVFRVXxFUVRZfE9EU0h8RXx8SUJNLlB8MDExNg",
            "Description": "INTERNATIONAL BUSINESS MACHINES ORD",
            "InstrumentType": "EquityQuote",
            "Status": "Valid"
        },
    ...

If you know the instrument type of your instrument, you can run a type-specific search, see

REST API Reference Tree for the spec on all available. If, for example, you know that the instrument is Equity, you can run Equity Search and pass Exchange identifier in:

{ {protocol}}{ {host}}{ {api}}Search/EquitySearch

{
    "SearchRequest": {
        "AssetStatus": "Active",
        "AssetCategoryCodes": null,
        "SubTypeCodes": null,
        "CurrencyCodes": null,
        "CompanyName": null,
        "Description": null,
        "DomicileCodes": null,
        "ExchangeCodes": [ "PAR", "SWX" ],
        "FairValueIndicator": null,
        "FileCodes": null,
        "GicsCodes": null,
        "OrgId": null,
        "Ticker": "IBM",
        "Identifier": null,
        "IdentifierType": null,
        "PreferredIdentifierType": null
    }
}

Once you have the RIC for the exchange at hand, you can request EOD for the required exchange:

{ {protocol}}{ {host}}{ {api}}Extractions/ExtractWithNotes

{
  "ExtractionRequest": {
    "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.EndOfDayPricingExtractionRequest",
    "ContentFieldNames": [
      "Ask Price",
      "Asset Category",
      "Asset Category Description",
      "Asset ID",
      "Asset Status",
      "Asset Status Description",
      "Asset SubType",
      "Asset SubType Description",
      "Asset Type",
      "Asset Type Description",
      "Bid Price",
      "RIC"
    ],
    "IdentifierList": {
      "@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
      "InstrumentIdentifiers": [
        { "Identifier": "IBM.N", "IdentifierType": "Ric" }
       
      ]
    }
  }
}

Hi @modaresi,

The suffix part of RIC indicates the exchange where that price information comes from. So, if you use RIC as an identifier, in your DSS queries, then that price information will be from the exchange specified in the RIC.

E.g. IBM.N implies that get the quote for IBM on NYSE, AAPL.O means get Apple quote from NASDAQ.

There are many DSS endpoints that can provide end of day pricing information. Please see the REST API help or use the DSS.NET sample application.
