Hello everyone, new guy here. I noticed when fetching a large amount of blocks (over 1k) that I was getting the error “Response closed without headers”, I wanted to know if there was some throttling involved, and if so: - what is the current limit?. - Is there a way to go over it, like a payed version or something?. thanks in advance. ---

hi @daniel1 ! The current limit rate is 500 requests per second per API for each unique client. What is your use case? I believe it is possible to increase the limit depending on your use case, but you may have to connect w/ someone from the team (: ---
