Hello @Lynn.chen

There are many endpoints that can provide data for chains. You can try Historical Chain Resolution (TickHistory) to expand a chain.

Other extraction endpoints like Terms And Conditions Extraction (DSS) and Tick History Extraction (TickHistory) can also work with chains - where the identifier is passed in as a chain RIC.

For exact scope of what you need to do - I would advise to raise a content query at LSEG MyAccount. We can help with technical/API related questions.

e.g. -

{
  "ExtractionRequest": {
    "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.TermsAndConditionsExtractionRequest",
    "ContentFieldNames": ["RIC"],
    "IdentifierList": {
      "@odata.type": "#DataScope.Select.Api.Extractions.ExtractionRequests.InstrumentIdentifierList",
      "InstrumentIdentifiers": [{
          "IdentifierType": "ChainRIC",
          "Identifier": "0#HO:"
        }
      ],
      "ValidationOptions": {
        "AllowHistoricalInstruments": True,
        "AllowInactiveInstruments": True,
        "AllowOpenAccessInstruments": False
      },
      "UseUserPreferencesForValidationOptions": False
    }
  }
}
