What is the query limit on Yahoo's Finance API?
What is the query limit for Yahoo's Finance API? Or where is the documentation that describes the limit?
For all of Yahoo's API's I've only been able to find general documentation for all API's. If you know where the documentation is for Yahoo's Finance API that'd also be appreciated. (I've been searching for a few days on Google, and on Yahoo's API sites, finally turned to friends at SO)
Thanks!

UPDATE:
Rate limits in YQL are based on your authentication. If you use IP-based authentication, then you are limited to 2,000 calls/hour/IP to the public YQL Web service URL (/v1/public/) or 20,000 calls/hour/IP to the private YQL Web service URL (/v1/yql/) that requires OAuth authorization. See the YQL Web Service URLs for the public and private URLs. Applications (identified by an Access Key) are limited to 100,000 calls/day/key*.
However, in order to make sure the service is available for everyone we ask that you don't call YQL more than 0.2 times/second or 1,000 times/hour for IP authenticated users and 2.7 times/second or 10,000 times/hour.
