My First Playground

/** * Welcome to the AppliedBlockchain test! * Clone this notebook before writing anything * * The script should be able to: * - Receive an ethereum address from the query (eg: ?address=0xc96b5bf11d1bceaff8646b37a7f83d1be878bae5) * - Validate if the address is valid, otherwise return this json { "error:": "Invalid ETH address." } * - If valid * - Check its balance via etherscan api * - Convert from wei to eth * - Return the balance in json format * * Infos: * An ETH address always begins with `0x` and has 42 characters * You can use the apiKey "testKey" for Etherscan * * Constraints: * - The node version used should be v6.12.2 * - The `endpoint` function will be the main function called * - JSON response expected * * Response expected: * { * "author": { * "name": "Your name", * "email": "Your e-mail" * }, * "address": "Address sent to the script", * "valid": "boolean expected", * // The below part is only visible if the address is valid * "balance": { * "wei": "balance in wei", * "eth": "balance in eth" * } * } * * When the test is finish, please send us the endpoint url by email to: blockchainweek2018@appliedblockchain.com * eg: https://runkit.io/oktapodia/5a5f67829fbc9a001258e093/branches/master * */ require("fast-json-stable-stringify"); var endpoint = require("@runkit/runkit/json-endpoint/1.0.0"); var etherscan = require("etherscan-api"); endpoint(module.exports, function(req, done) { // The ethereum address provided const ethAddress = req.query.address; // Your code should be written here return done({ hello: 'world!' }); })
