Hi @vlad.dimanshteyn,

Please note that this forum is for technical questions related to LSEG technology (more specifically, LSEG APIs). For content questions such as yours, we suggest using myrefinitiv.

With that said, I had a quick look for you. I see that you taged your question with "eikon-data-api" (EDAPI), but I would suggest using its successor, RD Lib. If you have access to EDAPI, you will have access to RD Lib.
Looking on Workspace, I foudn the following RICs that may be of interest to you: "USDSOFR=", "SOFR1MAVG=", "USDSR3L10Y=".
Personally, I would suggerst looking for the SOFR SWAP for a specific horizon (e.g.: SOFR SWAP 10 year). This is how I found the above.
Assuming you are coding in Python, you can find data in ways similar to this:

                

                 
# !pip install refinitiv-data
                 
import refinitiv.data as rd
                

                

                 
rd.get_history(
                 
    universe=["USDSOFR=", "SOFR1MAVG=", "USDSR3L10Y="],
                 
    fields=["TR.CLOSEPRICE", "CF_CLOSE", "CLOSE", "BID", "CF_BID", "CF_ASK", "CF_LAST", "PRIMACT_1"], # , "TR.ACCUMULATEDVOLUME"
                 
    start="2023-01-01",
                 
    end="2023-07-01",
                 
    # interval='daily'
                 
    )
