Get Transactions from wallet address in polkadot.js/api

Question

I want to know how I can get list of transactions and transactions info for specific wallet address in polkadot.js/api, especially for kusama.

const provider = new WsProvider("wss://kusama-rpc.polkadot.io");
const api = await ApiPromise.create({ provider });
const response = await api.rpc.eth.getTransactionByHash(hash);

I am not sure if above code is for transactions, however it is not running and cause error.

UnhandledPromiseRejectionWarning: TypeError: api.rpc.eth.getTransactionByHash is not a function

How can I get transactions from wallet address in polkadot.js/api?

To answer your comment around block-by-hash (there are no account -> transaction mappings on the RPCs, as per the linked answers in the comments above) -

You can use the getBlock RPC call. Since you are using the JS API based on your example -

// retrieve the block by hash, API decodes extrinsics
const signedBlock = await api.rpc.chain.getBlock("0x...blockHash here...")

// loop through extrinsics
for (let i = 0; i < signedBlock.block.extrinsics.length; i++) {
  const x = signedBlock.block.extrinsics[i];

  console.log(`
    isSigned=${x.isSigned},
    pallet=${x.method.section},
    method=${x.method.method}
  `)
}
