How can I get stock quotes using Google Finance API?

Question

The Google Finance Gadget API has been officially deprecated since October 2012, but as of April 2014, it's still active:

http://www.google.com/finance/info?q=NASDAQ:GOOG
http://www.google.com/finance/info?q=CURRENCY:GBPUSD
http://finance.google.com/finance/info?client=ig&q=AAPL,YHOO

You can also get charts: https://www.google.com/finance/getchart?q=YELP

Note that if your application is for public consumption, using the Google Finance API is against Google's terms of service.

Check google-finance-get-stock-quote-realtime for the complete code in python

There's a whole API for managing portfolios. *Link removed. Google no longer provides a developer API for this.

Getting stock quotes is a little harder. I found one article where someone got stock quotes using Google Spreadsheets.

You can also use the gadgets but I guess that's not what you're after.

The API you mention is interesting but doesn't seem to be documented (as far as I've been able to find anyway).

Here is some information on historical prices, just for reference sake.

I found this site helpful.

It links to an API yahoo seems to offer that is very simple and useful.

For instance:

http://finance.yahoo.com/d/quotes.csv?s=GOOG+AAPL&f=snl1

Edit: the api call has been removed by google. so it is no longer functioning.

Agree with Pareshkumar's answer. Now there is a python wrapper googlefinance for the url call.

Install googlefinance

$pip install googlefinance

It is easy to get current stock price:

>>> from googlefinance import getQuotes
>>> import json
>>> print json.dumps(getQuotes('AAPL'), indent=2)
[
  {
    "Index": "NASDAQ", 
    "LastTradeWithCurrency": "129.09", 
    "LastTradeDateTime": "2015-03-02T16:04:29Z", 
    "LastTradePrice": "129.09", 
    "Yield": "1.46", 
    "LastTradeTime": "4:04PM EST", 
    "LastTradeDateTimeLong": "Mar 2, 4:04PM EST", 
    "Dividend": "0.47", 
    "StockSymbol": "AAPL", 
    "ID": "22144"
  }
]

Google finance is a source that provides real-time stock data. There are also other APIs from yahoo, such as yahoo-finance, but they are delayed by 15min for NYSE and NASDAQ stocks.
