Yahoo Finance API Replacement. Google also offers a free finance API but, now that data providers are aware of Yahoo's redistribution redistribution, it seems likely that Google's service will be next. Google doesn't support the API, meaning developers can't get help when a call doesn't work or historical prices are un-adjusted.

I wanted to use Google Finance API to get stock data about the company but this API is deprecated since 2011/26/05.

What do you use as free API to get stock data in real time?

Updating answer a bit

1. Try Alpha Vantage API

For beginners you can try to get a JSON output from query such as

DONT Try Yahoo Finance API (it is DEPRICATED or UNAVAILABLE NOW).

• Here is a link to previous Yahoo Finance API discussion on StackOverflow.
• Here's an alternate link to Yahoo Finance API posted onGoogle Code.

For beginners, you can generate a CSV with a simple API call:

(This will generate and save a CSV for AAPL, GOOG and MSFT)

Note that you must append the format to the query string (f=..). For an overview of all of the formats see this page.

For more examples, visit this page.

For XML and JSON-based data, you can do the following:

Don't use YQL (Yahoo Query Language)**

For example:

2. Use the webservice

For example, to get all stock quotes in XML:

To get all stock quotes in JSON, just add format=JSON to the end of the URL:

Alternatives:

1. 1Forge Financial APIs

• Real-time rates for about 40 currency pairs are available here.

2. Financial Content API

• The documentation for this API is very good.

3. Open Exchange Rates

4. Oanda API

5. XE API

6. Xignite API

7. currencylayer API

8. Other API discussed at programmableWeb

I'm way late, but check out Quandl. They have an API for stock prices and fundamentals.

Yahoo Finance Rest Api

Yahoo Finance Api Documentation

Here's an example call, using Quandl-api download in csv

example:

They support these languages. Their source data comes from Yahoo Finance, Google Finance, NSE, BSE, FSE, HKEX, LSE, SSE, TSE and more (see here).

I'd suggest using TradeKing's developer API. It is very good and free to use. All that is required is that you have an account with them and to my knowledge you don't have to carry a balance ... only to be registered.

If you are still looking to use Google Finance for your data you can check this out.

I recently needed to test if SGX data is indeed retrievable via google finance (and of course i met with the same problem as you)

I followed the top answer and started looking at yahoo finance. Their API can be accessed a number of different ways, but I found a nice reference for getting stock info as a CSV here: http://www.jarloo.com/

Using that I wrote this script. I'm not really a ruby guy but this might help you hack something together. I haven't come up with variable names for all the fields yahoo offers yet, so you can fill those in if you need them.

Here's the usage

Download Finance Yahoo Com Api Search

loadStockInfo returns a hash, such that SpecificData['GOOG']['name'] is 'Google Inc.'

Finally, the actual code to run that...

How to call the API

All requests begin with a base url of http://finance.yahoo.com/d/quotes.csv and have arguments added onto the end.

The name of the requested stock is added through ?s=%40%5Eindex,stock. eg. ?s=%40%5EDJI,GOOG for Google stock.

Data to download

You then need to choose the data to request. This is done by appending a &f= followed by the different arguments. The list of arguments is available at the bottom of this file.

There are a huge number of data pieces you can download. Many of these were ambigous in the original documentation, and I haven't figured out exactly what they refer to e.g. the difference between ask and ask (realtime), so I've left them how they appear in the original docs.

These can be concatenated eg. if you wanted to download the ask, bid and change in percent you would use &f=abp2

Ratelimit

According to the Yahoo general API documentation, usage is capped at 2,000 requests/hour. This doesn't seem to apply to the finance API however, as I've performed 8,000 requests in 15 minutes before returning HTTP error 999. No true figure is known.

Examples

http://download.finance.yahoo.com/d/quotes.csv?s=%40%5EFTSE,ARM.L&f=sl1vop

This will return the stock ticker, current price, volume, opening price and closing price for the stock FTSEARM.L
