Fetch native network balance (aka ETH on Ethereum, MATIC on Polygon, AVAX on Avalanche, BNB on BSC, etc.)

Sequence Indexer GetEtherBalance Method:
  • Request: POST /rpc/Indexer/GetEtherBalance
  • Content-Type: application/json
  • Body (in JSON):
    • accountAddress (string) — the wallet account address
Example: GetEtherBalance MATIC balance of a wallet account address on Polygon using an API_Access_Key 
curl -X POST -H "Content-Type: application/json" -H "X-Access-Key: AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY" https://polygon-indexer.sequence.app/rpc/Indexer/GetEtherBalance -d '{ "accountAddress": "0x8e3E38fe7367dd3b52D1e281E4e8400447C8d8B9" }'

// Works in both a Webapp (browser) or Node.js:
import { SequenceIndexer } from '@0xsequence/indexer'

const indexer = new SequenceIndexer('https://polygon-indexer.sequence.app', 'AQAAAAAAAF_JvPALhBthL7VGn6jV0YDqaFY')

// try any account address you'd like :)
const accountAddress = '0xabc...'

// query Sequence Indexer for the MATIC balance on Polygon
const balance = await indexer.getEtherBalance({
	accountAddress: accountAddress,
})
	
console.log('tokens in your account:', tokenBalances)
