Quick Start

Good to know: A quick start guide can be good to help folks get up and running with your API in a few steps. Some people prefer diving in with the basics rather than meticulously reading every page of documentation!

Create address

const crypto = require('crypto');
const axios = require('axios');

// testnet
var hostname = "https://testnetrest.metacoin.network:20923";
// mainnet
// hostname = "https://rest.metacoin.network:20923";

axios.post(hostname + '/address/bykey', {
    'publickey': public_key
}, {
    proxy: {
    host: '127.0.0.1',
    port: 8888
    }
})
    .then(function (response) {
    if (response.status != 200) {
        return Promise.reject("Metacoin server response error");
    } else {
        return Promise.resolve(response.data);

    console.log(mtc_address);
    })
    .catch(function (error) {

        console.log("Address not found");
    } else {

Good to know: Using tabs to separate out different languages is a great way to present technical examples or code documentation without cramming your docs with extra sections or pages per language.
