Recommendation for EOD data

K

I'm wondering if anyone can recommend an end-of-day data service that might meet my needs. I primarily want historical end-of-day data for stocks on the NYSE and NASDAQ that go back as many years as possible. Also I want to be able to have it in .csv format. A lot of the companies I looked at seem to provide there data using a proprietary software that downloads it, but I was more interested in writing my own code with c++ and fetching the data using the curl library. It would be easiest if there was an end-of-day service that makes their data available as does yahoo finance that uses an API where you simply can type in the url with the necessary information related to the stock you want and it returns a .csv file. Can anyone recommend a service that can be used in that fashion that provides accurate data and that is available in a timely manner after the close of the stock exchanges? All I mainly want is the opening and closing prices for the stock each day and perhaps even the total number of outstanding shares although this latter information isn't critical.

Best to keep you own data;
citigroup[c] has reverse stock split, 10 to 1. Most charting services dont[some do] mention that; C @ $50 ,$49is really $5, $4.90 , a penny stock.
 
To keep your own data is silly. Do you really have the resources to maintain data like a professional data vendor and fix any variances between them? Do you know how many splits/spinoffs/special dividends/code changes/new listings/delistings you need to do each day?

I tried to do it and it's a fool's exercise.
