In the BSC documentation, it says that we can make 10K/5mins RPC requests to their servers. Do you guys know if it's 10K per app or user?
Since these are public endpoints, they are probably monitoring your usage by your IP address. So you can only do 10K requests/5min from your IP. It doesn't matter if you have more applications or accounts (since you don't need an account to use these endpoints anyway)
If you're looking for a higher rate limit BSC node, you should check out my company moralis.io. You can get a free BSC node with 3600 reqs/1 min.
For transparency, there are also other free node providers that will give you BSC nodes, like getblock.io or quicknode.com, but their free tiers are not as generous as moralis. For example, getblock.io will give you 40K reqs/day, while moralis with it's 3600 RPS will give you 5 million reqs/day for free.
