I am using 0x API for my dex and I am expecting at least 4k users on my app. But I don't see any subscription plan or anything on 0x documentation to increase or at least know my API rate limits. Is it that possible 0x API can handle 4k users or maybe higher. I want to know what is the capacity of the 0x API?
I got one link there no description related to my query, and it is not working also.
