Notably absent are the X-RateLimit-Max and X-RateLimit-Current headers that show up in API queries to the sites themselves.

For the time being, as everything on Stack Auth is "query when needed (which is rarely), cache for a day", the inclusion of rate limit headers is kind of pointless.

Basically, if you ever need to check that you aren't hitting your quota... you're probably doing something wrong. There are naturally exceptions, but still in 99% of all cases the headers are pointless.

If Stack Auth ever grows methods that merit more aggressive calling, it'll gain some indication of rate limiting.

  • Well, one of my example scripts is designed to pull the rate limit from the last request's headers. When that happens to be a request with StackAuth, I am without that information... which is unfortunate. Commented Feb 13, 2011 at 3:12
