Current steam cooldowns on requests to price history, item listings and orders histogram

[botan]

Hi, I'm writing a parser and I need to make requests to  price history, item listings, and orders histogram,

and I'm always getting 429 after different amounts of requests and cooldowns also like random,

I was wondering if someone already faces this issue and knows roughly which request intervals I should set.

Also, I noticed that the cooldown system for each path is different, I can get 429 on listings but still can make requests to orders without problem.

 

Thank you all!
