Etherscan API

Development of a NEXTGEN Version has started - please stand by


A way to access the etherscan.io api using promises. Fetch a diverse set of information about the blockchain.

Mainnet

``javascript
var api = require('etherscan-api').init('YourApiKey');
var balance = api.account.balance('0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae');
balance.then(function(balanceData){
console.log(balanceData);
});
`

Example in the wild

* Polymer3 based example

use a own instance of axios

`js
const axios = require('axios');
const {
init,
pickChainUrl
} = require('..');


const chain = pickChainUrl(null);
const client = axios.create({
baseURL: chain,
timeout: 10000
});

var api = init('apikey', null, 10000, client);
`
