I am currently doing a script to retrieve data, I have a personal RPC that accepts 600 calls/second, but my script is making more than 600 calls/second using the getParsedTransactions() method via the web3.js library, so my question is: Is there a way to limit the number of calls/second?

    are you using getParsedTransactions() to process 600 signatures, or are you running it 600 times once-per-signature? You should just give it less signatures to process at a time, it's not web3.js's responsibility to go slower for you. If you are processing batches of signatures just make them smaller. Almost always web3 will let you limit a large result set

Yes there is a way to do this by using the batchSize parameter in the provider.send function to reduce the number of requests made in a single batch, this will assist the number of request by second made.

const setProvider = new SolanaWeb3Provider('https://testnet.solana.com',{batchSize = 1});

const makeRequests = [
   //Your Request

setProvider.send(makeRequests, (err, res) => {

  // Deal with any response
