# Transaction API

This class is util to fetch transaction related information from the blockchain. All operations go by default through the public official NULS explorer API. But it is up to you to configure your own NULS node host as API provider

class TransactionApi {
  constructor(config?: ApiServiceConfig)
  async getTransactions(type: TransactionType, pageNumber?: number, pageSize?: number): Promise<TransactionListResponse>
  async getTransaction(txHash: string): Promise<TransactionResponse>
  async validateTransaction(txHex: string): Promise<ValidateTxResponse>
  async broadcast(txHex: string): Promise<BroadcastTxResponse>
}

# Fetch transaction info by hash

import {TransactionApi} from '@nuls.io/transaction'

const transactionApi = new TransactionApi({
  url: 'https://nulscan.io',
  chainId: 1,
})

const tx = await transactionApi.getTransaction('ad2ad7bc2f5f002bf58a607f1ba3cb4cbb951d1df9a882ad9b68d76618838e7d')

console.log(tx)
// {
//   hash: "ad2ad7bc2f5f002bf58a607f1ba3cb4cbb951d1df9a882ad9b68d76618838e7d",
//   type: 4,
//   height: 5575,
//   size: 357,
//   ...
// }
