Q:
Is there a limit on number of calls?
A:
There was a post about rate limiting being introduced a while back, so yes, there are now limits. (…or soon will be, IDK.)
Lawton, perhaps that should get a sticky with details?

Ah yeah that’s a good point, I’ll see if I can figure out how to make a sticky post.
The rate limit is currently 600 requests/minute and is exposed in the X-Rate-Limit-Limit response header. It’s per-IP address.
