`javascript
import GeminiAPI from 'gemini-api';

const restClient = new GeminiAPI({ key, secret, sandbox: false });
const websocketClient =
new GeminiAPI.WebsocketClient({ key, secret, sandbox: false });

restClient.getOrderBook('btcusd', { limit_asks: 10, limit_bids: 10 })
.then(console.log)
.catch(console.error);

websocketClient.openMarketSocket('btcusd', () => {
websocketClient.addMarketMessageListener(data =>
doSomethingCool(data)
);
});

// The methods are bound properly, so feel free to destructure them:
const { getTicker } = restClient;
getTicker('btcusd')
.then(data =>
console.log(Last trade: $${data.last} / BTC)
)
