We would ideally like to be able to call a chain RIC, see which RICs are returned so we can then do EOD/Intraday extractions, without doing an extraction on the entire chain which will consume our quota. sampleR RIC

Hello @jose.uy0,
Understood.
The way to do so without an Extraction request, would be via Search.
And the search that supports chain expansion is HistoricalChainResolution, so I believe if the customer is DSS, they will have to expand the chain as part of their required Extraction request.
If they extract the same chain repeatedly, they may wish to store the extracted instruments returned by their first request, and submit them separately as RICs into the next requests, as potential optional approach.

Hello @jose.uy0 ,
Absolutely. Would HistoricalChainResolution Search satisfy the requirement:
{
{protocol}}{
{host}}{
{api}}Search/HistoricalChainResolution
Request
{
"Request": {
"ChainRics": [
"0#HO:"
],
"Range": {
"Start": "2021-06-17T00:00:00.000Z",
"End": "2021-06-17T00:00:00.000Z"
}
}
}

Hi @zoya.farberov This is great but client does not have TIck history enabled. only DSS.
Is there any other way?
Thank you
