@Venkata satyanarayana Machari veera (CIS) Thank you for reaching out to us!
I understand your requirement to get the Reserved Instance (RI) Price list by series name using APIs. We do not surface RI prices yet except in our public API https://prices.azure.com/api/retail/prices.
Here is the public documentation on how to use filtering https://learn.microsoft.com/en-us/rest/api/cost-management/retail-prices/azure-retail-prices.
I'm checking for an alternative to get Meter Names RI price list. I shall get back to you once I come up with something that can be of some help.
Update:
Can find the details using the azure pricing calculator.
