Stock quotes API? [closed]

Question

I'm trying to put together a simple RSS widget (for my wordpress blog) that will show a list of stocks, or markets, and their current prices.

I cant seem to find an API for this data anywhere - can anyone suggest such a thing (perhaps as an RSS feed?)

Answer 1

Yahoo have an (undocumented) Stock Quotes API as part of their Finance API

Basically, http://download.finance.yahoo.com/d/quotes.csv?s=GOOG&f=ll will return the price for GOOG stock in CVS format

The s parameter is the stock symbol. You can specify multiple by separating them with +

quotes.csv?s=GOOG+YHOO‎ 

The f parameter is the data format code, which I found documented from this Python script (which is also how I discovered the API..):

code   description  l1     price c1     change v      volume a2     avg_daily_volume x      stock_exchange j1     market_cap b4     book_value j4     ebitda d      dividend_per_share y      dividend_yield e      earnings_per_share k      52_week_high j      52_week_low m3     50day_moving_avg m4     200day_moving_avg r      price_earnings_ratio r5     price_earnings_growth_ratio p5     price_sales_ratio p6     price_book_ratio s7     short_ratio 

They are all documented on this page

The data is returned as a comma separated file, which should be utterly trivial to parse in any language

You can also use Google's Finance API to get Stock Quotes in a slightly round-a-bout way

Basically you create a Google Spreadsheet, and use the GoogleFinance function:

=GoogleFinance("GOOG"; "price") 

..then use the Spreadsheet API to access that value

I found this via ["Introducing the Google Finance API"](http://googlified.com/introducing-the-google-finance-api/ ), and "How to get a real-time stock quote using Google API" describes this is more detail, including a simple bash shell-script to access the data (I think it could be simplified by making the spreadsheet publicly accessible)

There are already a few Wordpress plugins; among others:
