In DataScope, after I search on Cusip and get a list of items, clicking open one of the items will open the attached screen. Is any of the data in Cross Reference tab exposed via DataScope REST API? I am primarily trying to get the values for Original Place of Listing -> Price Source under Symbols section and the Identifier Type/Identifier under Cross Reference section. Thanks!
Hi @cabissi
Yes the API can do this, and provide much more data via View & Extract.
In the .NET Example Application the 'On Demand' Direct HTTP example is:
POST https://hosted.datascopeapi.reuters.com/RestApi/v1/Extractions/ExtractWithNotes HTTP/1.1
Authorization: Token <your_auth_token_goes_here>
Prefer: respond-async
Content-Type: application/json; odata=minimalmetadata
{
"ExtractionRequest": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.SymbolCrossReferenceExtractionRequest",
"ContentFieldNames": [
"Quote ID",
"Asset Type",
"Asset Type Description",
"Security Description",
"Instrument ID",
"Instrument ID Type",
"Reuters Editorial RIC"
],
"IdentifierList": {
"@odata.type": "#ThomsonReuters.Dss.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
"InstrumentIdentifiers": [
{
"Identifier": "IBM.N",
"IdentifierType": "Ric"
}
],
"ValidationOptions": null,
"UseUserPreferencesForValidationOptions": false
},
"Condition": {
"IdentifierTypes": [
"Ric",
"Sedol",
"Cusip",
"Wertpapier",
"Valoren"
],
"DaysAgo": 14,
"AllXRefIdentifierTypes": true
}
}
}
The full model for this On Demand example can be viewed via the API Reference Tree: https://hosted.datascopeapi.reuters.com/RestApi.Help/Context/Operation?ctx=Extractions&opn=ExtractWithNotes&grp=On%20Demand%20Extraction (select ExtractionRequestBase = SymbolCrossReferenceExtractionRequest)
The .NET Example Application as well as other key resources can be found here (GUI : Help > REST API Help): https://hosted.datascopeapi.reuters.com/RestApi.Help/Home/Index , I'd recommend some of the pages such as 'Key Mechanisms' and 'Extraction Limits' in the 'SDK' menu, as well as the 'Best Practices' guide located in the Developer Community: https://developers.refinitiv.com/en/api-catalog/datascope-select/datascope-select-rest-api/documentation#best-practices-and-limits-for-data-scope-select, one of the key parts of the API is to get the bearer Token (valid for 24 hours) from the response to re-use the Token in any requests the the DSS API in the 24 hour period:
POST https://hosted.datascopeapi.reuters.com/RestApi/v1/Authentication/RequestToken HTTP/1.1
Prefer: respond-async
Content-Type: application/json; odata=minimalmetadata
{
"Credentials": {
"Username": "<Your Username>",
"Password": "<Your Password>"
}
}
Best regards,
Gareth
