There are, somewhere in our Fantasy specific TOS, but I think that we still might not have that posted and I'm not sure how much detail they really go into. As of right now, I think we're employing the "reasonable person" standard, ie, please don't break our machines by spamming us with dozens of requests per minute. You should probably stay in the same vicinity as the limits for the YQL interface, so try to utilize the flexibility of services to minimize the number of requests you need to make. Help us help you. :PIf there are any use cases that you're unsure about, feel free to ask. I generally didn't see anything about Fantasy Sports as necessitating a high volume of service requests, but I'd be curious what you're trying to do that would prove me wrong.
