Yahoo Finance All Currencies quote API Documentation

Question

I ve being using this feed for a long time  I believe Apple does it as well in one of the mac widgets  but what is really curious is that I simply can t find any documentation for it  I ve tried google and everything   http   finance yahoo com webservice v1 symbols allcurrencies quote  I can see people using different parameters like view basic date Ymd  currency true but it s horrible there isn t anything official   For now I am using these parameters   format json and callback list sometimes     But it is still a mystery for me  Does anyone know the real truth about it because it seems Yahoo is trying to hide it somewhere else

I m developing an application that needs currency conversion  and been using Open Exchange Rates because I wouldn t be paying since the app is in testing  But as of September 2012 Open Exchange Rates is gonna be paid for non-personal  so I checked out that they were using the Yahoo Finance Webservice  the one that  doesn t exist   and looking for documentation on it got here  and opted to use YQL   Using YQL with the Yahoo Finance table  yahoo finance quotes  linked by NT3RP  currencies appear with symbol  ISOCODE X   for example   ARS X  for Argentine Peso   AUD X  for Australian Dollar   USD X  doesn t exist  but it would be 1  since the rest are rates against USD   The  price  value on the OP API is in the field  LastTradePriceOnly  of the table  For my application I used the  Ask  field

As NT3RP told us that          we  Yahoo   don t have a Finance API  It appears some have reverse engineered an API that they use to pull Finance data  but they are breaking our Terms of Service      So I just thought of sharing this site with you  http   josscrowcroft github com open-exchange-rates    update  site has moved to - http   openexchangerates org   This site says      No access fees  no rate limits  no ugly XML - just free  hourly updated exchange rates in JSON format       update  Free for personal use  a bargain for your business     I hope I ve helped and this is of some use to you  and others too

From the research that I ve done  there doesn t appear to be any documentation available for the API you re using  Depending on the data you re trying to get  I d recommend using Yahoo s YQL API for accessing Yahoo Finance  An example can be found here   Alternatively  you could try using this well documented way to get CSV data from Yahoo Finance   EDIT   There has been some discussion on the Yahoo developer forums and it looks like there is no documentation  emphasis mine       The reason for the lack of documentation is that we don t have a Finance API  It appears some have reverse engineered an API that they use to pull Finance data  but they are breaking our Terms of Service  no redistribution of Finance data  in doing this so I would encourage you to avoid using these webservices    At the same time  the URL you ve listed can be accessed using the YQL console  though I m not savvy enough to know how to extract URL parameters with it
