How to get historic Bitcoin Price Index using coinbase or any other open source API

Question

I would like to get a history of the bitcoin price. For example, I would like to be able to provide a start_date and end_date for a search/filter. Is there any open-source and trusted API with almost accurate prices for this?

I have noticed that coinbase only returns the spot/current price and I cannot pass more params to filter

curl https://api.coinbase.com/v2/prices/spot?currency=USD

I have also used the coin desk but the prices are not accurate.

https://api.coindesk.com/v1/bpi/historical/close.json?start=2019-08-10&end=2020-08-11&currency=zar

Answer 1

I would recommend you to use the CoinMarketCap API if what you want are historical prices.

There are also libraries like ccxt where you can probably find this information as well.

However, you have to keep in mind that due to the number of exchanges these prices are approximations, and there is no such a thing as a "unique" price for bitcoin.
