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)

Solution

See the Yahoo Query Language Usage Information and Limits page. This is for all of the YQL APIs, not just the Finance API.

YQL Rate Limits:

What this means:

Using the Public API (without authentication), you are limited to 2,000 requests per hour per IP (or up to a total of 48,000 requests a day).
Using the Private API (with OAuth authentication using an API Key), you are limited to 20,000 requests per hour per IP and you are limited to 100,000 requests per day per API Key.

The above answer was originally posted here by me.
