Error 403 (eth_getTransactionCount)

I need to send ~130 transactions in about 1-2 seconds to the ropsten network. Using Web3 and the eth_getTransactionCount method, I get a 403 error. What is the maximum sending rate allowed? When sending test payments with a 1s delay all is fine

Hi @httsmvkcom, and welcome to the Infura community!
This probably has to do with rate-limiting - what kind of account do you currently have? It also may be due to network congestion - have you been able to try again and successfully send the txns?
