Is there any API limits

Hi Greg.

By dead space I mean the app appears to simply hang; it isn't hanging its waiting for dropbox to reply to all of its requests, replies that never it seems come back.  That said it does work, if I re-run the app, just moments later it retries the requests, and gets the response that the links already exist.

So the limit that is coming up seems to be linked to the number of links i request and get an almost immediate response too. It not an app killer as limitations go, I don't really see the problem unless I request 450+ links over a few seconds, but I am little worried since I don't know what is happening and if I do manage to get app live on the apps store I don't want to watch it go up in smoke as it becomes more successful and fires off more and more requests for links that get silently throttled on the dropbox end.

It would be better if I could monitor/throttle my app/give the user some feedback as oppose to guessing what the limits are.
