Where can I get historical quote data?

[DaveSkender]

There are many places to get stock market data. Check with your brokerage or other commercial sites.
If you're looking for a free developer API source, here's a few:

• Polygon.io
• Alpaca Markets
• TwelveData
• FinnHub.io
• Alpha Vantage
• iexcloud.io

If you're looking for some C# packaged APIs for the cryptocurrency world, some of which may provide historical data, @JKorf has been building a bunch here: https://github.com/JKorf/

I would like to add iexcloud.io , certainly if you are interested in European market.

Another potential source of data is the MetaTrader 5 terminal itself through their Python package MetaTrader5, for those using that platform anyway. The major advantage is that you'll be working with the brokers' data that you'll potentially be trading on.

See the above list of professionally managed data sources. Most have a freemium model to support developers and hobbyists.
Feel free to add your favorites or other API helpers in the discussion area below.

There is another good and free web site to download historical data (US, World, ...). No API, but there are .CSV file easily to read and load => https://stooq.com/db/h/

@DaveSkender I would like to suggest my newest API library to be added to this list. I created a wrapper API for Yahoo Finance that can get you any information you are looking for. I currently support getting top trending stocks, historical price data, dividends, stock splits, capital gains, recommended stocks, and I have many other items I will be adding in the next few days.

For anyone interested in Crypto data, I used this: https://www.cryptodatadownload.com/data
Lately, it needs a free account signup, to download, though...

Anybody have any success using the Robinhood API lately?
