Looking for free API’s with historic price data

hey there! Been working on a small back test tool, mainly for my crypto investments. Currently I'm Iooking for a free crypto API to fetch prices, also historical prices. Until now I have been using yfinance, but some tickers like PEPE-USDT are not working, just as an example.

So far I have looked into the big ones like CoinMarketCap or CoinGecko, but all of them do not include historic price data and require premium subscriptions.

Maybe somebody ran into this before, any help would be appreciated 👍
