I'm looking for a well documented, easy to use API that provides data on the majority of cryptocurrencies. That data should include the 1 hr, 24hr, and 7 day price changes, as well as the entire history of the volume, and price for each crypto. I've looked into some APIs but none have provided this sort of comprehensive information. There are many great sites that have access to this sort of data, so it must be out there. Any help is appreciated! Thanks!
Most exchanges offer API solutions for market data. Here are some examples:
CryptoCompare has an API that aggregates data from many exchanges, and they also offer many query parameters. Link: CryptoCompareAPI
Additionally, many block explorers provide APIs for blockchain account information.
This ZChain Playlist shows how to use PowerShell to query the ZChain ZCash block explorer API.

I think this one is best, they don't have restrictions https://www.coinlore.com/cryptocurrency-data-api
Almost each crytpo exchange has its own API, you can integrate it for free and get the data. The first challenge that they are too many (more than 200 exchanges so far), that means 200+ API integrations which cost a lot of time. The second challenge is that these exchanges provide a lot of data and after start collecting you will need to take care of many TBs which is an additional servers cost.
That's why there are such services like Coinmarketcapi professional API, coinapi and CryptoAPIs.io
I made a compare and i picked https://cryptoapis.io/ because they have more exchanges, more options and cheaper.
Founder & developer of https://tardis.dev here. It's an API I've built that provides high frequency cryptocurrency historical raw market data — tick-by-tick trades, full order book depth snapshots & delta updates, quotes, liquidations and more available via HTTP and WebSocket API. Based on that data you can build OHLC candles, volume bars, dolar bars etc.
