Building with Amberdata.io is as simple as a few a few lines of code:

For Historical OHLCV -

let config = {headers: {"x-api-key": "YOUR_API_KEY_HERE"}};
const getHistoricalOHLCV = (pair) => axios.get(`https://web3api.io/api/v1/market/ohlcv/${pair}/historical`, config);

See source here.

For live order book updates -

// Create WebSocket connection.
const socket = new WebSocket('wss://ws.web3api.io?x-api-key=YOUR_API_KEY_HERE');

// Connection opened
socket.addEventListener('open', function (event) {
    console.log('Connection opened - ', event);
    socket.send(`{"jsonrpc":"2.0","id":0,"method":"subscribe","params":["market:orders",{"pair":"eth_btc","exchange":"gdax"}]}`);
});

// Listen for messages
socket.addEventListener('message', responseHandler);
