I wasn’t able to find any info about this. What is the rate limit on calling the API?

Maybe there needs to be an FAQ sticky for general information like this?

There is currently no limit on calls. Although it is always best to cache your data to reduce stress on their API servers.

I have my script set to 12 second intervals, with it running in the background during a boss fight, it add some lag. I think 30-60 seconds is plenty, 40-45 second might be a good sweet spot (this is probably what I’ll set my script to).
