IEX has an official, documented, supported, relatively clean, and entirely free API for their market data: https://iextrading.com/developer/docs/ It's just US stocks, and quote data is just for their exchange (and you can get the deep book if you're interested in that stuff). But they have basic company info: earnings estimates, split info, dividend info, etc. as well.
Earlier quoted context omitted.
Downloading a csv isn’t scraping.
I don't know if the csv was meant to be an api or just giving the option to someone visiting yahoo finance (and therefore viewing ads) the ability to download data they viewed. If you go straight to the data and bypass the ads, you are sort of scraping.

Yeah. It's been on & off for a while but yesterday looks like it went for good. I had to fix my script switching to: http://www.bloomberg.com/markets/api/quote-page/{CURRENCY_PA...
https://polygon.io - real-time stock data APIs
They broke functionality on their own pages, yikes. E.g. the export button on the desktop version of https://finance.yahoo.com/quotes/MMM,IBM/view/v1?ql=1
You'd think after you take down an API you've be furiously checking the server logs for any referrers coming from inside the house.

Yes, IEX only. But still great service, great tools. All for free. I mean how often do you see websocket support? If you want or need high res quotes from all exchanges including options data, you can also take a look at Nanex http://www.nanex.net/ And thanks to everyone for posting great links ;)
