Hi devs !

I’m trying to run a backtest on the confidence interval for a handfull of feeds.  
This is a key input for a protocol we are testing.

Is there a way to download a batch of historical data with the confidence interval ?  
In the API, in only found endpoints to get one datapoint at a time, which is inefficient and cumbersome, or for price only feed. ([Benchmarks - Swagger UI](https://benchmarks.pyth.network/docs#/TradingView/tradingview_history_route_v1_shims_tradingview_history_get))

Do you have any pointer or suggestion ?

Thank you for any help!
