Hello @n.khambu.swetha ,

Please see this previous discussion thread on obtaining exchange rates, in my understanding, the request for OAE (RIC = CMP) should be along the same lines:

{
                {protocol}}{
                {host}}{
                {api}}Extractions/ExtractRaw
{
    "ExtractionRequest": {
        "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.IntradayPricingExtractionRequest",
        "ContentFieldNames": [
            "Currency Code",
            "Base Currency Code",
            "Mid Price",
            "Price Decimals",
            "Trade Date",
            "Trade Time",
            "Last Update Time",
            "Instrument Snap Time",
            "Security Description"
        ],
        "IdentifierList": {
      "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",  
      "InstrumentIdentifiers": [{
        "Identifier": "CMP",
        "IdentifierType": "Ric"
      }],
      "ValidationOptions": null,
      "UseUserPreferencesForValidationOptions": false
    },
        "Condition": {
            "ScalableCurrency": "true"
        }
    }
}

Is this what you are looking for?

If this is not what you are looking for, I would suggest to first better identify the required content:

Are you able to request and obtain this information via DSS GUI? If yes, please share the details and we will try to help with the same request via API.

If you need help identifying content, suggest to consult with Refitnitiv content experts directly via Refinitiv Helpdesk Online -> Content -> DSS and once the content is identified, request it via API.
