Realtime currency webservice

Question

Anyone know of a real-time currency rate webservice with frequent update (multiple pr. min.). Needed for a small android app I'm building, so needs to be free.

Answer 1

You can try Yahoo. It is free and easy to use.

For example, to convert from GBP to EUR: http://download.finance.yahoo.com/d/quotes.csv?s=GBPEUR=X&f=sl1d1t1ba&e=.csv

gives you data in csv format which can easily be parsed.

Answer 2

Real time financial services are usually not available for free. You will find a lot of delayed services ( tipically 15 min ) for free, but you have to make sure licensing allow you to use it in your own application as well.

Answer 3

you have some webs where you can take this information. The problem... usually you need pay for this service. Same examples :

• http://www.xignite.com
• http://fxtrade.oanda.co.uk/trade-forex/api/
• http://forex-automatic-trading-systems.com/developers/api.htm
• http://forexfeed.net/developer/php-forex-data-feed-api

Answer 4

Have you tried with http://openexchangerates.org ?

You can use it's The Forever Free Plan with following features provided.

• Hourly rate updates

• Daily historical data

• 1,000 API requests per month

Answer 5

I would recommend European Central Bank. They provide a daily xml feed, nice and simple.

Answer 6

I would suggest Mondor's web service, especially the WebAPI one. Not free, but could be about 5$ per year, depending from your architecture. Anyway, here's the link: http://mondor.org

Edit: apparently, they have free keys now, or I missed them previously.
