Package Exports

etherscna-api
etherscna-api/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (etherscna-api) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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

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

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);

For testnet and L2s usage
