etherscan api

import { etherscanPageData } from 'easyscan'

async function etherscanAPIDemo() {
    const etherscan = etherscanPageData('1', 'API_KEY')
    // page = 1 will scan from page1 to page end.
    const { resume, stop } = etherscan.logs.getLogs({ address: '0xdac17f958d2ee523a2206206994597c13d831ec7', page: 1, offset: 5000, startblock: 1, endblock: 'latest', topic0: '0xddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef' }, (pageData, pageIndex, accData, isFinish) => {
        // pageData : current page data
        // pageIndex : current page index (index from 0)
        // accData : accumulated data ,it is [...page1,...page2,...page3,...]
	// isFinish : request is finished or not.
    })
    setTimeout(()=>{
        // stop paging request
        stop()
        setTimeout(()=>{
            // resume paging request
            resume()
        },10000)
    },10000)
    // It provides a jsonrpc provider.
    const tx = await etherscan.provider.getTransaction('0xb84d6525eedce0e0dab1f94830db53e2b078d2e6c510affffe700113a7c68578')
}

tronscan api

async function tronscanAPIDemo() {
    const tronscan = tronscanPageData('TronGrid')
    // page = 1 will scan from page1 to page end.
    const { resume, stop } = tronscan.account.txList({ address: 'TDqMwZVTSPLTCZQC55Db3J69eXY7HLCmfs' }, (pageData, pageIndex, accData, isFinish) => {
        console.log(pageIndex, accData.length,isFinish)
    })
    // It provides a jsonrpc provider.
    const tx = await tronscan.provider.getTransaction('5e28141b3a2f94551ea3fecd363aadd85db3515b2a35388f0aefac7518bf3898')
