API throttling limits? http response 429

Thanks for your answer - but yes, I know what I means and thats why i'm asking here. "Too many requests" is kind of useless as I need to know which limitations exists so I can adjust everything. According to the public information the script should run fine but it doesnt.

This is from last night:

22:59: 8 calls

23:00: 9 calls

23:01: 18 calls

23:02: 5 calls

23:03: 7 calls

23:04: 6 calls

23:05: 10 calls

(same pattern until)

23:35: 3 calls

23:36: 6 calls

23:37: 4 calls and then fail

Any other requests are not running, except a very few for triggering refreshes. But nothing that would end up in the documented limitations. Invoked multiple times etc. is also not possible as its a simple batch script. Which also waits untail the file is completely downloaded and then take the next one.
