What is the maximum flickr API limit available and how do you go about getting it?

Question

According to the Flickr API documentation:

If your application stays under 3600 queries per hour ... you'll be fine.

According to Yahoo Developer documentation:

Access through YQL is limited to 10,000 signed calls per hour

I am currently using Flickr's direct API and I am unfamiliar with YQL. Is it necessary for me to rewrite using YQL to obtain the 10,000 call limit or is there a way to increase my limit while using the direct flickr API?

Why do the two APIs to the same service have different limits?

Answer 1

According to Yahoo the lower limit applies. They also state that commercial licenses with higher limits are available.
